eclipse 3.3M7, I am trying to build a RCP using birt engine. I tried birt
2.1.2 and 2.2RC1.
How is birt RunAndRenderTask gets the classloader? I am getting wierd
class def not found exception on springframework/AopConfigException when I
am trying to initialize a class through spring in OPEN javascript . (I am
using scripted data source) I am doing this way because this class
depends on many other classes and I don't want to initialize them all by
myself.
I am thinking this is a classloader issue because the classloader I set
for the RunAndRenderTask is able to get AopConfigException class. This is
what i did:
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
HashMap<String, ClassLoader> contextMap = new HashMap<String,
ClassLoader>();
contextMap.put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY,
ReportView.class.getClassLoader());
Class foo =
ReportView.class.getClassLoader().loadClass("org.springframework.aop.framework.AopConfigException ");
System.out.println("FOO: " + foo);
task.setAppContext(contextMap);
and console prints out this:
FOO: class org.springframework.aop.framework.AopConfigException
however in open method javascript this exception comes out when I am
trying to get the class through spring, any help would be great!!

Ian,
If the class is in the plugin registry you should be able to access it
from script like:
importPackage(Packages.org.eclipse.core.runtime);
mybundle = Platform.getBundle(“bundle-name”).
cl1 = bnd.newInstance();
xyz = cl1.getMyMethod();
