birt as a separate war and passing parameters

gebuh

We have the 2.6.1 birt viewer deployed to jboss 5.1 as a standalone WAR so that multiple applications(in other WARs on our server) can access it. Currently reports are fetched passing parameters via URL: 
<pre class='_prettyXprint _lang-auto _linenums:0'>http://our.awesome.app.com/warThatHoldsBirtViewer/preview?__report=reportName&__format=pdf&reportParam=1234</pre>
 
We must stop this. It looks as if we could do this via the Report Engine API using something like: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>IReportRunnable runnable = reportEngine.openReportDesign(reportPath);
...
IRunAndRenderTask task = reportEngine.createRunAndRenderTask(runnable);
...
task.setParameterValue(key, reportParams.get(key));
</pre>
So in an action class method I'd call create this instance to generate the report. 
But I'm assuming that means the report engine is bundled within your application. Is there a way I can do this remotely? 
We're using Seam 2.2.0. 
Any advice would be helpful.

I am not exactly sure what you are asking. Do you want to start the engine remotely?

I'm not sure, the Birt viewer war is deployed on the same app server as our other applications. I want to pass parameters to the viewer from our Seam app without using GET (params in the URL). 
I don't start the engine(I don't think) now, unless that is done by deploying it to the server.

Would using the tag libraries accross context be an option?

It looks like that's for creating actual reports embedded in html view. 
Is it possible to use these taglibs in jsf components?

I tried the eclipse taglib. Followed the directions, but these are jsp tags and apparently won't work with RichFaces. I'm running a Seam app. Seam has a birt plugin, but the set up looks like you'd have to include BIRT as a part of the Seam app. I'm trying to configure it to use BIRT from another context(it's in a separate war). I'll update with my progress.
