How to reduce BIRT WEB app deploy time on Websphere?

Hello, I have developed a simple BIRT WEB application and successfully deployed on Websphere 7. I developed my WEB app as specified in the Eclipse website below. 
 
<a class='bbc_url' href='http://wiki.eclipse.org/Servlet_Example_(BIRT)_2.1'>Servlet Example (BIRT) 2.1 - Eclipsepedia</a> 
 
But the only problem is my WAR file size is 40MB! According to the above link I have to include BIRT Runtime Lib, Configuration and Plugins (jars) in the WAR file. Plugins jars are too many. Due to this it is taking me long time to deploy my WEB application on to Websphere. 
 
other option exploring -- 
I created shared lib on websphere and included this shared library to the deployed BIRT WAR but I am getting OSGI error. -- "Cant startup the OSGI framework". 
<a class='bbc_url' href='http://publib.boulder.ibm.com/infocenter/wasinfo/v5r1//index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/tcws_sharedlib.html'>http://publib.boulder.ibm.com/infocenter/wasinfo/v5r1//index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/tcws_sharedlib.html</a> 
 
I am guess BIRT expect the jars to be present in the WAR file in the same folder structure as specified in the above eclipse link. I am going to explore this option further. 
 
 
Can any one please let me know the better way to develop BIRT WEB application? Any suggestion will be really helpful. 
 
Thanks.

The error you are getting is because the plugins can not be found. You will notice in that example that it uses a PlatformServletContext. This class has one method getHome(). You can write your own to specify the location of the birt Plugins and configuration directory. The PlatformServletContext creates a plugins and configuration directory in the temp folder and explodes all the plugins there. You can also use the PlatformFileContext which just looks for a BIRT_HOME, which you can set in the env or on the EngineConfig.

Thanks Jason I was using PlatformServletContext, due to this I am including plugins in WEB-INF/Platform directory. thats why i have size problem with WAR file. 
 
May be i will try the following, as specified in the BIRT website.. 
<a class='bbc_url' href='http://74.125.95.132/search?q=cache:Z5gvpFGG44kJ:www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.php+PlatformServletContext&cd=1&hl=en&ct=clnk&gl=us'>Report Engine API</a> 
 
So if you are deploying an application to the Web that uses the BIRT API and it is not contained in a war you can use the default and set your engine home to something similar to: 
 
config.setEngineHome( servletContext.getRealPath("/WEB-INF")); 
 
But I have to hard code the path in servlet

You can always implement your own PlatformContext. It only has one method getHome, which you could make read an env variable etc.

I wrote one that actually unziped a zip file and placed the runtime in a folder of my choosing.

That is cool..:) may be I can do some thing similar to that. implement PlatformContext to read an env variable.
