Hi,
 
I'm using birt to generate xml files.
In order to do that, i created a plugin : org.eclipse.birt.report.engine.emitter.xml.XMLReportEmitter..
From this plugin, i generate a jar that i'm using in a war to create the xml file.
 
So I have two projects : the emitter plugin and the web app using it.
 
While calling this plugin (jar) from the web app on the production server, i got this error :
(In the test server it's fine)

Both of my servers (prod and test) have the same config (windows servers/glassfish 3.1.2.2, java 7 (u67).
 
In order to call the emitter, i do :
 
final IRenderOption xmlOptions = new RenderOption(options); 
 xmlOptions.setOutputFormat("xml"); 
 xmlOptions.setOutputStream(response); 
 runAndRenderTask.setRenderOption(xmlOptions); 
 runAndRenderTask.setEmitterID("org.eclipse.birt.report.engine.emitter.xml.XMLReportEmitter");
 
My dependencies for the report in the war are :
 
<dependency> 
 <groupId>org.eclipse.birt.runtime</groupId> 
 <artifactId>org.eclipse.birt.runtime</artifactId> 
 <version>4.4.2</version> 
</dependency>
 
and the jar generated from the plugin using tycho.
<dependency> 
 <groupId> 
 org.eclipse.birt.report.engine.emitter.xml 
 </groupId> 
 <artifactId> 
 org.eclipse.birt.report.engine.emitter.xml.XMLReportEmitter 
 </artifactId> 
 <version>${plugin-emitter-xml}</version> 
 </dependency>
 
 
You we'll find the plugin project in attached files.
 
Do you have any clues? Do I need to register in an other way this plugin? (how does it work?), on glassfish?
 
 
Thanks in advance,
 
Caroline

The error indicates it's class path related in that it cannot load the org.eclipse.birt.report.engine.emitter.ContentEmitterAdapter.
This class located inside the org.eclipse.birt.eport.engine jar.
I would start by making sure this can be loaded through your class path properly. This should resolve the error you are current getting.

cmalnoe

Thanks for your response.
 
The point is this class is in the classpath, as it's in the org.eclipse.birt.runtime-4.3.1.jar (or 4.4.2 i tried both), which is included in the war web-INF/lib.
Maybe there is conflicts while invocing this class?
 
 
Moreover, it looks like it depends on the environnement as it's work fine in my test web server but not in my prod server.
I put my 2 environnement on debug mode FINEST : It looks like it doesn't execute the same way (not same logs)
In the prod server (error) i got :

Should I do something specific to add it to the classpath? (in glassfish)? I tried putting this jar(org.eclipse.birt.runtime-4.3.1.jar) in the lib/endorsed of glassfish which leads me to deployment errors...
 
 
Thanks,
Caroline

If you have it working in your test environment, I think the best action would be to investigate what is different between the test and prod environments.
 
There is a chance a conflict could be causing an issue that is preventing the class from loading properly.
Do you have anything that could be causing a conflict in prod that is not in test?
Do you have any other differences between the libraries deployed in prod vs your test environment?

cmalnoe

I did compare the 2 environments: glassfish version (domain.xml same), java used by jvm, environnment variables, OS... I don't know what to check more.
 
Between the prod and test this is the same war.
 
what do you means by "Do you have any other differences between the libraries deployed in prod vs your test environment". librairies (jar) in glassfish? Nothing different here.
 
Do you have an idea what should i look for? Can it be linked to osgi issues?
