couldn't instantiate DesignEngine running Tomcat with security enabled

Hi, 
 
i m running Tomcat with security settings enabled which means that i use a catalina.policy to restrict permissions of my webapp. My webapp uses the design engine API to open and modify reports which are then generated to PDF using the Report Engine API. 
I simply added following line to my catalina.policy: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
grant codeBase "file:${catalina.base}/webapps/MyApp/-" {
permission java.security.AllPermission;
};
</pre>
 
After adding this line the report engine runs just fine and i can generate reports without any problems. But instantiating the design engine causes massive problems. At first it failed cause the design engine API would like to access C:\Documents and Settings\<MyUsername>\My Documents\eclipse\workspace (???). After giving my webapp appropriate rights to read and write this folder code below causes engine to be null. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
DesignConfig config = new DesignConfig( );
config.setBIRTHome(pathToBIRT)
Platform.startup( config );
IDesignEngineFactory factory = (IDesignEngineFactory) Platform
.createFactoryObject( IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY );
engine = factory.createDesignEngine( config );
</pre>

Can you try setting a different tmp directory and applying permission to it? Try:

config.setProperty("tmpDir", "c:/temp");

Before creating design engine.
