Post your exception, some code (at least some code around your exception), and tell us, which of OOo's JARs and which other JAR files you deploy where in Tomcat. Otherwise I can give no further advice.

Here's the code:
Code: Select all   Expand viewCollapse view
private void getContext() {
      try {
         String oooExeFolder = "/usr/lib/openoffice.org/program/";
         this.context = BootstrapSocketConnector.bootstrap(oooExeFolder);
          if(context == null) {
             System.err.println("ERROR: Could not bootstrap default Office.");
          }
      } catch(BootstrapException e) {
          e.printStackTrace();
          System.exit(1);
      }
    }

The error happens on this.context = BootstrapSocketConnector.bootstrap(oooExeFolder)
The error I get is:
Code: Select all   Expand viewCollapse view
com.sun.star.comp.helper.BootstrapException: no office executable found!

This is all part of a servlet that is going to use Impress, so this is part of code to do that. The code all runs perfectly in Eclipse, but still fails when the war file is deployed to Tomcat 6.

You still haven't told which JAR files you use and deploy.

Anyway, for whatever reason, something goes wrong. So the next step I would take is to debug the application. My bootstrapconnector.jar contains all the source code, too. So it should be possible to remote debug your application running in Tomcat from Eclipse. Doing this, you should take a closer look at the OOoServer.start() method. There you'll find the lines
Code: Select all   Expand viewCollapse view
if (fOffice == null)
    throw new BootstrapException("no office executable found!");
where your exception occurs.

Once you connect to OpenOffice to perform your conversions how do we disconnect when the server shuts down?

Sometimes my files get locked and I cannot delete them. I have to manually go into task maanger and shut down soffice.bin and then I can delete the files.

There is no disconnect available. And even if OOo should offer something like this, you might not be able to call it, after the server shut down.

zoharat wrote:Sometimes my files get locked and I cannot delete them. I have to manually go into task maanger and shut down soffice.bin and then I can delete the files.

If the soffice.bin process is still running, it didn't shut down. Although it happens from time to time, that soffice.bin stops processing function calls which you named here shutting down. But ok, this is just wording, and not very helpful for you ;-)

Anyway, you're totally right: OOo causes trouble from time to time. Sometimes it shuts down completely, so there is no longer a soffice.bin process running, and you should have no problems with deleting your files. And sometimes OOo stops responding and blocks every further function call. If this happens, I simply kill OOo the hard way. Some time ago I posted an OOo killer class here http://www.oooforum.org/forum/viewtopic.phtml?p=59186#59186. And for simplicity here is that code again:
Code: Select all   Expand viewCollapse view

import java.io.InputStreamReader;

public class KillOpenOffice
{
    /**

    * Perhaps it supports more OS, but it has been tested
    * only with this three.
    *
    * @throws IOException  Killing OpenOffice didn't work
    */
    public static void killOpenOffice() throws IOException
    {
       String osName = System.getProperty("os.name");
       if (osName.startsWith("Windows"))
       {
          windowsKillOpenOffice();
       }
       else if (osName.startsWith("SunOS") || osName.startsWith("Linux"))
       {
          unixKillOpenOffice();
       }
       else
       {
          throw new IOException("Unknown OS, killing impossible");
       }
    }

    /**
    * Kill OpenOffice on Windows XP.
    */
    private static void windowsKillOpenOffice() throws IOException
    {
       Runtime.getRuntime().exec("tskill soffice");
    }

    /**
    * Kill OpenOffice on Unix.
    */
    private static void unixKillOpenOffice() throws IOException
    {
       Runtime runtime = Runtime.getRuntime();

       String pid = getOpenOfficeProcessID();
       if (pid != null)
       {
          while (pid != null)
          {
             String[] killCmd = {"/bin/bash", "-c", "kill -9 "+pid};
             runtime.exec(killCmd);

             // Is another OpenOffice prozess running?
             pid = getOpenOfficeProcessID();
          }
       }
    }

    /**
    * Get OpenOffice prozess id.
    */
    private static String getOpenOfficeProcessID() throws IOException
    {
       Runtime runtime = Runtime.getRuntime();

       // Get prozess id
       String[] getPidCmd = {"/bin/bash", "-c", "ps -e|grep soffice|awk '{print $1}'"};
       Process getPidProcess = runtime.exec(getPidCmd);

       // Read prozess id
       InputStreamReader isr = new InputStreamReader(getPidProcess.getInputStream());
       BufferedReader br = new BufferedReader(isr);

       return br.readLine();
    }
}

You can find more about the Windows tskill command, that I used in the OOo killer class here http://technet.microsoft.com/en-us/library/bb490806.aspx for example.

If I use the boostrapConnector.disconnect method , it kills the soffice.exe. Not the soffice.bin process.

Besides killing it directly is there any other way to stop the soffice.bin process.

Re: [Java solution] "no office executable found!"

Hi,

I've recently used the BootstrapSocketConnector with success for a web app - I've tried it on both Windows XP and OpenSolaris 10 (101b) and it worked just fine. However, when I tried it on Linux I get an error.

I'm using OpenOffice 3.0 latest
CentOs 5.2 32 bit fully updated
Sun Java 6.0

This class is useful to me because I need to connect from a webapp. In my webapp I package all the OO jars supplied as normal in the SDK into my war and rely on none from the host platform.

I've set my UNO_PATH env variable. Unlike OpenSolaris 10 on Linux I seemed to have two path choices, but I've tried with both, with the same results. These being:

export UNO_PATH=/opt/openoffice.org/basis3.0/program/
export UNO_PATH=/opt/openoffice.org3/program/

I've bounced tomcat (in my case) whenever I've changed any env variables and I know the webapp is reading them ok and passing to the BootstrapSocketConnector constructor.

The error I get is an exception with the message "null" - as far as I can tell, the stack trace is:

com.sun.star.comp.helper.BootstrapException
at ooo.connector.BootstrapConnector.connect(BootstrapConnector.java:129)
at ooo.connector.BootstrapSocketConnector.connect(BootstrapSocketConnector.java:68)
at ooo.connector.BootstrapSocketConnector.connect(BootstrapSocketConnector.java:45)
at ooo.connector.BootstrapSocketConnector.bootstrap(BootstrapSocketConnector.java:82)
...

I realise the jar has source, so I will endeavour to add some more logging or debug if possible - but I'd really like to get this working asap so if anyone has any ideas then I'd really appreciate them. Failing that, if I manage to solve the problem I will report back with the details.

Any help much appreciated!

Hi,

quick update on this. I think it was a combination of things...

firstly, the correct default path for OO3 on Linux (RH etc) seems to be the second one, i.e.

export UNO_PATH=/opt/openoffice.org3/program/

I basically replicated the whole setup I'd tried to do over a terminal on a headless box, on a similar machine with a desktop/display manager so I could see what was going on.

I think what happens is the first time after installing, when soffice is started it launches the registration wizard - and thus hangs.

when I checked on the box where it wasn't working, I am getting a number of soffice processes being launched (so bootstrap is working) but they block when called from the api - I think they must be stuck at this first step - because this is the first time it's ever been launched, it would never be run as a regular user from the desktop.

So, a different problem to solve - but it appears not to be related to this handy jar library - so sorry for any confusion! :)

So use the parameter -nofirststartwizard. Take a closer look into the bootstrapconnector JAR file. It contains the example class BootstrapSocketConnectorExample which demonstrates the usage of -nofirststartwizard to get around the problem you described:
Code: Select all   Expand viewCollapse view
...
    private static void convertWithConnector(String loadUrl, String storeUrl) throws Exception, IllegalArgumentException, IOException, BootstrapException {

        // Create OOo server with additional -nofirststartwizard option
        List oooOptions = OOoServer.getDefaultOOoOptions();
        oooOptions.add("-nofirststartwizard");
        OOoServer oooServer = new OOoServer(OOO_EXEC_FOLDER, oooOptions);

        // Connect to OOo
        BootstrapSocketConnector bootstrapSocketConnector = new BootstrapSocketConnector(oooServer);
        XComponentContext remoteContext = bootstrapSocketConnector.connect();

        // Convert text document to PDF
        convert(loadUrl, storeUrl, remoteContext);

        // Disconnect and terminate OOo server
        bootstrapSocketConnector.disconnect();
    }
...

The crucial line of code for you is oooOptions.add("-nofirststartwizard");

Fantastic, that looks like the exact solution to my exact problem! Thanks ever so much, I won't be able to try this properly on the machine in question until Monday now but I'm confident this was the cause of my problem and the solution you recommend will fix it.

Thanks very much for the help and the example code :)

(Very useful helper library by the way, really glad I found it!)

Hi, just to close the loop on this - I've tried this out on my headless box and it's now all working fine :)

so thanks very much for the assistance!

Just one question. Even after disconnecting, two office processes "soffice" and "soffice.bin" remain running - is this normal / expected?

I notice if I run many reports, I don't get any additional process instances, so I think it's stable (not leaking resources), just wanted to check that once soffice is started, it's meant to remain running (which would make sense to me).

Yes, it is normal. And if you don't like it, you can kill OOo. This thread contains a post covering killing OOo.

Hi hol.sten,

thanks for your work! Your utility works really nice when used on Windows Vista and helped me after hours of frustration. However the bootstrap fails on my Mac OS X machine. The office process gets started correctly but the connection attempts fail with "connection refused" and i get stuck in this loop of BootstrapConnector.java.

Code: Select all   Expand viewCollapse view

// wait until office is started
for (int i = 0;; ++i) {
  try {
    xContext = getRemoteContext(xUrlResolver);
    break;
  } catch ( com.sun.star.connection.NoConnectException ex ) {
    // Wait 500 ms, then try to connect again, but do not wait
    // longer than 5 min (= 600 * 500 ms) total:
    if (i == 600) {
      throw new BootstrapException(ex.toString());
    }
    Thread.sleep(500);
  }
}


Only difference in my setup of the two machines is the classpath, which of course respects the different locations of the java_uno.jar, juh.jar and so on. The integration is done using fairly exact your sample code.
I just wanted to ask if you (or someone else reading this) has faced the same problem and can provide some insights or hints.

Thank you in advance, Thomas

Sorry to read that. I cannot assist you here, because my system isn't running on Mac OS X. But if anyone is delivering such a system to my doorstep, I will look into it ;-)

Thomas, can you tell me, which version of OOo you're using on Windows Vista and which on Mac OS X. Is it the same? Did you try on Mac OS X OOo 3.0.0 or 2.4.x or both versions? If not both, can you try more than just one version of OOo on Mac OS X?

Can you post the stack trace, too? bootstrapconnector.jar was Created-By: 1.5.0_14 (Sun Microsystems Inc.). So it's unlikely that you get the exception from one of the class files of bootstrapconnector.jar whilst using Java 1.5.0_8 on Windows XP.

And which line of your source code w2p.java is line number 13? That's hard to guess from the program fragment you posted above.

Where are you developing your application? Do you use an IDE? If so, which one?
Do you have multiple JDKs and/or JREs on your computer installed? Which versions are you using for building and for running your application. They cannot be the same.

Googling you'll find a lot of links covering "java.lang.UnsupportedClassVersionError: Bad version number in .class file" errors. Examples:
- http://www.techienuggets.com/Comments?tx=606
- http://lkamal.blogspot.com/2008/04/java ... error.html

My guess is that your problem is not caused by using bootstrapconnector.jar, but from mixing different JDKs on your computer for building and running your application.

So you're using different JDKs on your computer and in your IDE. That can cause problems.

You already told us. What you still haven't told us, although I already asked explicitly, which line of your source code w2p.java is line number 13? That's hard to guess from the program fragment you posted above.

dasha311 wrote:and i change the jdk version,it aslo has the Exception.

Where ever you changed that. Did you recompile your project after changing the JDK?

dasha311 wrote:i see the bootstrapconnector Created-By: 1.5.0_14 (Sun Microsystems Inc.),do i have to use the jdk 1.5.0_14????

No. And I still think that you're not having problems only with bootstrapconnector.jar. If you want to be sure of that, remove the bootstrapconnector.jar from your projects build and run path, unzip the jar, copy the source code from the jar into your Java project and recompile everything. The bootstrapconnector.jar does not contain only the class files, it contains the complete source code, too. So if your problem is caused by bootstrapconnector.jar, use its source code instead.

I have been using this solution and it has been working great until I installed OpenOffice 3.0.1 (upgrade from 3.0.0).

After digging into this a bit, I discovered that the soffice executable in 3.0.1 can't be launched from outside of the /program directory.

If I attempt to launch it from outside of the program directory, the following error is displayed to the console (or thrown during runtime, in the case of trying to launch OOo from my program).

>> No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting

I posted a question here:
viewtopic.php?f=17&t=17547

but have yet to receive any response, so I am hoping someone on this thread might be able to help find a solution or report a bug to the OOo development team.

Thanks in advance,

John

Due to some complaints about bootstrapconnector.jar I gave it a try on my computer running Ubuntu 9.04, OOo 3.0.1 (1:3.0.1-9ubuntu3), NetBeans 6.5 (6.5-0ubuntu2.1) and Java 6 from Sun (6-14-0ubuntu1.9.04).

In NetBeans I created a new project and added one simple class file of Java code:

Next step was to download bootstrapconnector.jar from this thread and to put it into some folder (I used /home/holsten/dev/NetBeansProjects/lib). Now I had to locate juh.jar, jurt.jar, ridl.jar and unoil.jar. I found them in the folder /usr/share/java/openoffice and copied them into the same folder as bootstrapconnector.jar. Finally I added all five JAR files to the compile-time libraries in the NetBeans project properties.

After setting the main class oootest.DocumentToPdfWithFilterData in the NetBeans project properties I started debugging the class but didn't get any error like "No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting" or "java.lang.UnsupportedClassVersionError: Bad version number in .class file". So I'm still puzzled what causes these errors.

All I got was "** (soffice:7120): WARNING **: unable to get gail version number" at the line "XComponentContext xContext = BootstrapSocketConnector.bootstrap(oooExeFolder);". But it is only a warning and caused no problems creating the PDF files. Googling for this warning pointed to some threads describing this error as a font related problem with the OOo version of Ubuntu Jaunty.

Hi Hol.sten,

we use the bootstrapconnector.jar in our project and would now like to know under which license the library is made available since we want to distibute it with our LGPL project.
Could you be so kind an include the license in the jar and state it on the first page?

Best regards,
Markus

I never intended to use a license. I had the idea, wrote some code (mostly based on source code from OOo's source code, like I mentioned on the first page), put the source and class files in a JAR and made it available here. Is that a problem for you?

Well, if I include the jar file in a project without knowing the license for it, then it is a problem to distibute the project since you did not explicitly allow it (i.e. with using LGPL).

As you can read in the credits section in the first post of this thread, not everything of the source code was written by me. I named all the sources and as far as I know they are free of some sorts. Finally I put all the source files and the compiled class files in a JAR and added it to the post. If you don't want to use the JAR, extract the source code and take what you need and do with it what you want.

I'm not a lawyer and I don't have the slightest clue if or if not it might be possible to put the JAR under any license of some sorts. Sorry. If someday someone can tell me how I can put the JAR under a license, I'll do so. Up till then, do with the source what you want.
