The move to a jar-based runtime makes it difficult to remove the built in emitters and replace them with alternatives.

In would say that either the report engine should dynamically detect emitters that replace the built in emitters, or it should provide an API for specifying the emitters to be used.

You can set default emitter for a format by API in engine config:
  setDefaultEmitter( String format, String emitterId )

There is no way to do this in the viewer though.

Jason,

Do you mean set a default emitter by URL parameter? Or you mean on GUI?

Comment 4 Jason Weathersby

I meant through the viewer export dialog.  I suppose if they are just using the URLs they could use the __emitterid parameter.  Any way to modify the .js files to point to the new emitter?

I am having issues with this as well. I have created a fresh install and tried the hack listed below but it is not working at all for me.

Below is the error I get when trying the hack listed below.

- Fatal error occurred when try to startup report engine.

Did you do this:

I then opened the META-INF folder and deleted everything but the MANIFEST.MF. I modified this file to look like:
Manifest-Version: 1.0
Bundle-Vendor: Eclipse.org
Bundle-Name: BIRT Runtime SDK
Bundle-SymbolicName: org.eclipse.birt.runtime
Bundle-Version: 3.7.0.v20110615-1818

Take a look at this blog:

the birtworld blog show how to include tribix emitter into web viewer.
Do you know the way to do the same with a the runtime engine ?

Comment 9 Jason Weathersby

You would use the same approach, except instead of copying to the web-inf/lib you would just add the jar(s) to the classpath like the reportengine/lib jars.

Julie - Can you clarify how you got this to work?

I have installed the BIRT Runtime 3.7 and I am using the genReport.bat file to help automate some monthly reports.

I would like to be able to replace the default xls emitter.
