Hi, I'm new to BIRT,
I'm trying to generate the report and populate it in a jsp through servlets using struts framework.
I'm using the "birt-runtime-2_6_2".
I got the exception " org.eclipse.birt.report.engine.api.EngineException: Can't create data engine.
at org.eclipse.birt.report.engine.executor.ExecutionContext.openDataEngine(ExecutionContext.java:874)
Caused by: java.lang.SecurityException: class "org.mozilla.javascript.ContextFactory"'s signer information does not match signer information of other classes in the same package "
while I try to call the task.run();
Trace:
*****

// Check if the classloader is different from the one in use.
if (originalClassLoader != null && !originalClassLoader.equals(Platform.getContextClassLoader())) {

}
// Open report design

// Build the output options and set the response content type.

task.run();
task.close();
} catch (EngineException e) {
e.printStackTrace();
