 Posted: Mon Jun 11, 2007 5:52 am Post subject: NoClassDefFoundError Exception (Bootstrap) |
 |
|
When I try to run the Servlet Example coming from the OpenOffice.org_2.2_SDK, then I receive the following Exception:
| Code: |
javax.servlet.ServletException: Servlet execution threw an exception
root cause
java.lang.NoClassDefFoundError: com/sun/star/comp/helper/Bootstrap
ConverterServlet.convertDocument(ConverterServlet.java:225)
ConverterServlet.doPost(ConverterServlet.java:132)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
|
Line 225 in the ConverterServlet.java is the following one:
| Code: |
XComponentContext xcomponentcontext = com.sun.star.comp.helper.Bootstrap.createInitialComponentContext(null);
|
I am using the Makefile which comes with the java example.
Any ideas why?
Thanks! |

Thanks hol.sten for the reply,
I went through all your links a tried some of the test, which were described. I tried that one: http://www.oooforum.org/forum/viewtopic.phtml?t=19474&highlight=classpath and was surprised why it works only if you set the OOOLIBPATH while you are executing the .bat file???
My set's are as follow:

OK, never the less, I am desparated trying to run my Servlet and it still not working? I saw in this Post: http://www.oooforum.org/forum/viewtopic.phtml?t=50715&highlight=servlet that you have to tell Tomcat where it can find the OpenOffice.org classes? I don't know where??? Can you tell me how to setup Tomcat so I can run my OOo Servlets?
Thanks! |

I found this in the settings/std.mk file:
| Code: |
SDK_JAVA_UNO_BOOTSTRAP_FILES=\
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader$$CustomURLClassLoader.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/InstallationFinder.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/InstallationFinder$$StreamGobbler.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/WinRegKey.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/WinRegKeyException.class$(SQM) \
-C $(CLASSES_DIR) $(SQM)win/unowinreg.dll$(SQM)
|
Maybe all the loader classes are important for Tomcat??? |

Anyway, regarding my servlet problem, I did put the jar files in the Tomcat directory as you said and now I am getting at least a different Exception:
| Code: |

I put those jar files in the following directory: CATALINA_HOME/shared/lib.
Here is the test method I am trying to execute in my servlet for a better understanding:
| Code: |
public void runODF() throws IOException
{
com.sun.star.uno.XComponentContext xContext = null;
Runtime runtime = Runtime.getRuntime();
String path = "C:/Program Files/OpenOffice.org 2.0/program/soffice.exe";
runtime.exec( path );
try
{
xContext = com.sun.star.comp.helper.Bootstrap.bootstrap();
if( xContext != null )
{
System.out.println("Connected to a running office ...");
} else {
System.out.println("Not connected to a running office ...");
}
xContext = null;
System.exit(0);
}
catch( Exception e )
{
System.err.println( "Cause Exception: "+e.getCause() );
System.err.println( "Message Exception: "+e.getMessage() );
e.printStackTrace();
System.exit(1);
}
}

Maybe you should really look harder!

As I already told you, in my bat file one line defines OOOLIBPATH and uses that variable with %OOOLIBPATH% in the following line. I named that variable OOOLIBPATH with three O, three! Not two like OOLIBPATH as in your last post. And nothing with underscores like OO_LIB_PATH.
Ok, now again: OOOLIBPATH, OOLIBPATH, and OO_LIB_PATH are the names of three different variables! And you didn't set OOOLIBPATH in your environment so it has to be set in the bat file.
But anyway, even if you got it now, this doesn't solve your Tomcat problem!

Which has already been discussed in this forum. And has been the topic of the first link I posted in my first reply in this thread for you!
| bolekovnik wrote: | | I put those jar files in the following directory: CATALINA_HOME/shared/lib. |
Which is in vain, if you're using the bootstrap connection mechanism!

As far as I know this will not work in Tomcat.
So I repeat it for you for the last time in this thread: Use the older connection mechanism with Tomcat or use a Java application which is not running within Tomcat in conjunction with something like RMI. I don't provide any further links, because this thread already contains enough unread links... |

I messed something up and that's why nothing is running.
Sorry for bothering you with the CLASSPATH and OOLIBPATH. I was confused about the names, but figured out, that it has to be OOLIBPATH and not SOMETHING_ELSE.
I need to reinstall my server anyway and will try out everything from scratch.
Thanks for your help! |

Thank you for your clarification

If you still try Tomcat, try the older connection mechanism and not the bootstrap connection mechanism. Although it seams that the bootstrap connection mechanism is easier to handle, it has some disadvantages as you can read in the various threads I posted here.
