Loading reports from Classpath? [message #520004]

Is it possible to load report files from the Classpath? I would like to be able to package up my report files in my WAR for deployment. I am deploying to a shared hosting environment where I will not have easy access to the file system.

Craig,

Are you using the Viewer? What app server is it being deployed to? The
Viewer war comes with two test reports already in the war. Do they work?

Craig,

You can specify a url if you are using the viewer like:

http://localhost:8080/WebViewerExample/frameset?__report=htt p://localhost:8080/myreportcontext/myreport.rptdesign&sa mple=my+parameter

If the report designs are served up like this, I assume the library files must also be accessible. If my library includes database connection credentials, this creates a nasty security hole. Sure I can use the JNDI data source, but then I can not test from within the Eclipse report designer.

Being able to load reports off of a classpath location (ie, a package directory) would solve both of my problems (limited filesystem access, and security).

We are deploying to WebLogic. I have not tried the viewer war yet, but I will do that and get back to you. However, I assume the answer is in how the engine.openReportDesign("relative/path/to/file.rptdesign") behaves when setup as per the Servlet Integration example. Where does it look for that file?

Look at the web.xml for the working folder. You can also set the folder
for the resource directory for libraries.

Well, I tried deploying birt.war from the runtime distribution into my WebLogic instance. For some reason, when I try to access a report, I get ClassNotFoundException for Commons Logging LogFactory. It looks like the web app is not loading classes from its own WEB-INF/lib, which I find very odd.

Take a look at the Tomcat 6 note here:

OK, I am able to get this to deploy fine in Jetty (I have to include the commons logging lib just like for Tomcat), but on WebLogic I get the following error:

I have openned the birt.war and confirmed that the viewservlets.jar file is in WEB-INF/lib and contains the ViewerServlet class. As fate would have it, Google returns only 1 result for this specific error, a 2 year old post on Birt Exchange with no solutions. Ironic is the fact that the OP had the error with Jetty.

OK, here is some additional mystery. When I deploy with Jetty, if I go straight to the /birt/frameset?.... url for the report, I get this same NoClassDefFoundError on ViewerServlet. If I try to go to the index page at this point, it shows me a directory listing instead, with only WEB-INF and logs showing. Its like the deployment failed once the NoClassDefFoundError ocurred.

OK, so I shutdown Jetty, restart, go to the index page "/birt". Click on the link to the frameset URL....works perfectly. Am I crazy?

OK, so I have repackaged birt.war with commons-logging in its WEB-INF lib. The report viewer now shows up, but test.rptdesign is not working. I get the following error dialog:

"The viewing session is not available or has expired."

There is no stack trace.

This is really getting frustrating now. Restarting IE fixed the session problem, but the viewer now gets an error with the following stack trace:

Craig,

In the web.xml there is a setting to enable logging and a location. Can
you set the log level to FINE and post the log? Also what version of WL
are you using?

OK, I found the source of the problem, and when I am done I will check the 2.5.2 code and if this has not been fixed, I will submit a bug report.

The source of the problem is the following code in ScriptEngineFactoryManager.java (version 2.5.1):

	synchronized public IScriptEngineFactory getScriptEngineFactory(
			String language )
	{
		if ( factories.containsKey( language ) )
		{
			return factories.get( language );
		}
		IScriptEngineFactory factory = createFactory( language );
		factories.put( language, factory );
		return factory;
	}

The factories.get(language) call returns null for language = "javascript". Debugging this, the factories Map contains key "javascript", but its value is null. I am assuming this is a classloading issue. As it turns out, the weblogic.xml descriptor packaged in the birt.war is having no effect, so jars in the WEB-INF/lib are not being preferred over container jars. Sure enough, the rhino classes are in weblogic.jar. I used Eclipse webtools to generate a new weblogic.xml and test.rptdesign works great (test1.rptdesign gives an error, though...baby steps).

Now, the NPE is clearly a code path that should be handled. I'm going to file a bug report, but I'll go ahead and explain it here. The above code returns null to the following block in ScriptContext.getScriptEngine(String):

		IScriptEngineFactory factory = ScriptEngineFactoryManager.getInstance( )
				.getScriptEngineFactory( scriptName );
		if ( factory == null )
		{
			throw new BirtException( "No such script extension : " + scriptName );
		}

...but this exception is swallowed up the call stack in ExecutionContext.openDataEngine():

	public void openDataEngine( )
	{
		if ( dataEngine == null )
		{
			try
			{
				dataEngine = DataEngineFactory.getInstance( ).createDataEngine(
						this, needOutputResultSet );
			}
			catch ( BirtException bex )
			{
				addException( bex ); // Exception swallowed here!!!
			}
			catch ( Exception ex )
			{
				addException( new EngineException( ex.getLocalizedMessage( ),
						ex ) );
			}
		}
	}

This is being called from ExecutionContex.getDataEngine(), which returns null in this case. Line 123 in ReportExecutor.execute() is where it blows up:

context.getDataEngine( ).prepare( report, appContext );

For whoever may be having the same problem, here is the original weblogic.xml, followed by the one that is working for me:

<?xml version="1.0" encoding="UTF-8"?> 
  <!DOCTYPE weblogic-web-app 
    PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN" 
    "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd" >

<weblogic-web-app>
	<container-descriptor>
		<prefer-web-inf-classes>true</prefer-web-inf-classes>
	</container-descriptor>
</weblogic-web-app>

This works:

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app 
    xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd 
        http://xmlns.oracle.com/weblogic/weblogic-web-app
        http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
    <wls:container-descriptor>
        <wls:prefer-web-inf-classes>true</wls:prefer-web-inf-classes>
    </wls:container-descriptor>
</wls:weblogic-web-app>

I'm not sure why the DTD version doesn't work. Perhaps it has been deprecated (removed to be exact), or perhaps I have another bug to file with Oracle Wink

Craig,

Thanks for posting this. After you test 2.5.2 let me know and I will
put this on the wiki.

Thanks

Jason

I haven't tested on 2.5.2, but the offending code has not changed. Since the root cause was a WebLogic class loading issue, I'm going to assume the behavior will be the same.
