Help please - Report Engine does not work in deployed Eclipse Application

Hello,

I have an eclipse based application that generates rptDocuments and lists them to end users so they can export to pdf, html, xls, etc.

Both work perfectly if I run my application from eclipse ide (3.4.2), when I try the deployed application nothing happens and only have a log in <birt_home>/ReportEngine/configuration

!MESSAGE Bundle initial@reference:file:plugins/org.eclipse.birt.core_2.3.2.r232_20090204a.jar/ was not resolved.

Already checked and org.eclipse.birt.core_2.3.2.r232_20090204a.jar is in reportengine/plugins. Also tried to have reportengine plugins in my application dropins folder but still have the same error.

The code i am using to get engine instance is:

EngineConfig dConfig = new EngineConfig();
dConfig.setEngineHome(birt_home);
dConfig.setLogConfig(null, Level.OFF);
dConfig.getAppContext().put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY, this.getClass().getClassLoader());
engine = new ReportEngine(dConfig);

Can you please help me?

Thanks in advance

Is this plugin in the plugins directory?
org.eclipse.core.runtime

Hello Jason,

Thanks for your help.

Yes it is. In <birt_home>/plugins i have org.eclipse.core.runtime_3.4.0.v20080512.jar. I had already checked that, sorry i didn't refer it.

I also have in <my_app_home>/eclipse/plugins same plugin. Do you think that osgi framework can be confused loading 2 environments?... It doesn't seem very likely ...

Don't know where else to turn to. Already tried a lot of solutions posted in the net, like java.policy, birt home as jvm environment variable, with platform, without platform ...

Any other information I can give you?

Do you have all the plugins from the report engine download included?
birt-runtime-2_3_2\ReportEngine\plugins

Also verify that you have all of these plugins.
Require-Bundle: org.eclipse.core.runtime;bundle-version="[3.2.0,4.0.0)
";visibility:=reexport,com.ibm.icu;bundle-version="[3.4.4,4.0.0)";vis
ibility:=reexport,org.mozilla.rhino;bundle-version="[1.6.0,2.0.0)";vi

I have com.ibm.icu_3.8.1.v20080530.jar both in in <report_egine>/plugins and <my_app>/eclipse/plugins and org.mozilla.rhino_1.6.7.v20080214 only in report_egine>/plugins. 
 
My report engine config.ini is 
 
#Product Runtime Configuration File 
eclipse.product=org.eclipse.birt.report.engine.ReportEngineSDK 
osgi.bundles=org.eclipse.equinox.common@2:start, org.eclipse.update.configurator@3:start, org.eclipse.birt.core@start 
osgi.framework.extensions=org.eclipse.birt.api 
osgi.bundles.defaultStartLevel=4

I am not certain why you have plugins in two places but the report engine should start up where ever you set birt home. In your case is it
<birt_home>/ReportEngine

Birt home should point to a directory that contains the plugins and configuration directory. The configuration directory should only contain a config.ini

It should be started like:

IReportEngine engine=null;
EngineConfig config = null;
try{

config = new EngineConfig( );
config.setBIRTHome("C:\\birt\\birt-runtime-2_3_1\\birt-runtime-2_3_1\\ReportEngine");
config.setLogConfig(null, Level.OFF);
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
}catch( Exception ex){
ex.printStackTrace();
}

I have two places because my application is an eclipse RCP application. Should I place report engine plugins in my eclipse application plugins folder and set it as report engine home?

I will try the code you wrote and let you know later.

Thanks a lot!
Teresa

JasonW

If you already have the plugins in your app, you should not have to do a startup and you should be able to set birt home to "";

eg
IReportEngine engine=null;
EngineConfig config = null;
try{

config = new EngineConfig( );
config.setBIRTHome("");
config.setLogConfig(null, Level.OFF);
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
}catch( Exception ex){
ex.printStackTrace();
}

Hello Jason,

I was obviously approaching the problem in a wrong way, always thought that I needed a "Report Engine Home".
Googling what jars I really needed to include I came across an article of yours, don't know how I never did, and it is exactly the directions I need. I will try it now and let you know later how it ended.

Thank you!

Sounds good let me know.

Hello Jason,

Just finnished testing generating rptdocument, with success. I followed your article that i refered before, did not include report.model dependency though, is that a problem? I started adding birt plugins to myapp/plugins by try, whenever there was a log launching eclipse i added the dependency plugin. Used the code you've posted here also.

Now generating pdf, html, xls is still not working... do i need to include the emitters plugins in my <myapp>/plugins folder?

Thanks!

qos

Done, the emitters were missing. Everything is working now! (minus the debug that stoped working but that is secondary, i'll find out a way)

Thanks again for your help, precious as always.

Have a nice weekend,
Teresa

Glad to hear (read). Have a good weekend.
