Hello everyone,

I have reports deployed on Tomcat 8 using the Webviewer and they all work perfectly. My version of the BIRT runtime is 4.5.0 and the application is deployed in the webapps/birt directory of Tomcat.

The problem is that now, I have a report that has an imbedded script in the beforeFactory that starts with these lines:

importPackage(Packages.org.eclipse.birt.report.item.crosstab.core.de);
importPackage( Packages.org.eclipse.birt.report.model.api );
importPackage( Packages.org.eclipse.birt.report.item.crosstab.core.util);
importPackage( Packages.org.eclipse.birt.report.item.crosstab.core);
importPackage( Packages.org.eclipse.birt.report.model.api.elements);


Now, the script itself works since if I run it through Eclipse, it works without problem. On the other hand, when I put it on the webviewer, I end up with the following error:

birt.core.JavascriptCommonError ( 1 time(s) )
detail : org.eclipse.birt.report.engine.api.EngineException: There are errors evaluating script "importPackage(Packages.org.eclipse.birt.report.item.crosstab.core.de);

importPackage( Packages.org.eclipse.birt.report.item.crosstab.core);
importPackage( Packages.org.eclipse.birt.report.model.api.elements);

var eF = reportContext.getDesignHandle().getElementFactory();
var srt = eF.newSortElement();

if(params["pOrderBy"].value == "SC")
	srt.setKey("data[\"Total_GRCertificat/Certificat\"]")
else
	srt.setKey("data[\"nbfois_GRCertificat/Age\"]")
	
srt.setDirection(DesignChoiceConstants.SORT_DIRECTION_DESC);

var xtab = reportContext.getDesignHandle().findElement("tab");
var xtabhandle = xtab.getReportItem();

var rws = xtabhandle.getCrosstabView(ICrosstabConstants.ROW_AXIS_TYPE);
var lvh = rws.getDimension("GRCertificat").getLevel(0);

lvh.getModelHandle( ).add( ILevelViewConstants.SORT_PROP, srt );":

I've tested and any of the import statement will generate this error. My best guess is that the webviewer can't load the BIRT packages, but I don't know how to fix this. Anyone has any idea?

We're having exactly the same problem. The BIRT Runtime 4.5.0 was previously served in Tomcat 8.0.28 and everything was fine. Since we upgraded Tomcat to 8.0.32, we've been having the same errors. It seems unhappy about the "importPackage" statements.

Thanks for the reply Eason. In my case, I was able to go around the problem since all my script really needed were a few constants defined in other packages. So I removed the "importPackages" and replaced the constants with their values and everything started working.

Now as to what Tomcat's problem actually IS, I have no idea.

Apparently, in Tomcat 8.0.32, they "fixed" the class loader. This might be what's causing this strange bug. Here's the changelog if anyone wants to see for themselves:

I can now confirm that this is actually a bug in Tomcat 8.0.32 but apparently they fixed it and the problem should not reoccur in 8.0.33 whenever they decide to release it. Here's the link to their bugtracker:

Thanks! We just upgraded our Tomcat to 8.0.33, which solved the problem!
