Hi , 
 
I have run into the following error when trying to access the secured XML resource from the Report Web Viewer . 
 
Environment 
OS :Windows 2k3 SP2 
BIRT Report Engine Ver 2.6 
BIRT Report Designer Ver2.6 
Application Server : Websphere Application Server V7 
 
Following are the steps executed 
 
1. Imported the certificate from the secured resource using keytool utility. 
2. Was able to successfully access the secured XML resource (using <a class='bbc_url' href='https://<myserver:port>/<TestServlet>'>https://<myserver:port>/<TestServlet></a> from the BIRT Design Studio and was able to generate the report . 
3. Used the sample 'birt.war' supplied along with the BIRT ReportEngine to access the report 
4. In the 'birt.war' modified the following 
changed the web.xml BIRT_VIEWER_WORKING_FOLDER to point to the local directory where the report is stored 
5. Modified the config.ini in the WEB-INF/platform/configuration directory to include 'eclipse.security=true' entry and also modified the was.policy file to provide the permission for 'birt.war' 
 
When I access the report via the birt web app deployed on WAS I get the following error 
"Can not startup the OSGI framework 
org.eclipse.birt.core.exception.BirtException: Can not startup the OSGI framework

Hi Jason, 
Yes I did go over the bug and based on that made the following changes on Websphere Application Server 
a. Modified the was.policy file for birt to grant all permission for birt.war 
b. Changed the config.ini in WEB-INF/platform/configuration directory 
 
Hope that clarifies 
 
Thanks

Thanks for adding it.

Hi , 
 
On debugging the source the cause for the exception , the OSGILauncher.java seems to be the issue . 
 
Specifically the following line in the doStartup method is throwing InvocationException . 
bundleContext = runMethod.invoke( null, new Object[]{new String[]{}, null} ); 
 
I am not sure if this leads to configuration that needs to be done in WAS. 
 
Any ideas ? 
 
 
 
 
Enclosing the snippet of the doStartup method here 
 
OSGILauncher.java

Method initPropertiesMethod = clazz.getMethod("setInitialProperties", new Class[]{Map.class} ); //$NON-NLS-1$ 
 
if ( initPropertiesMethod != null ) 
{ 
System.setProperty( 
"osgi.framework.useSystemProperties", "false" ); //$NON-NLS-1$ //$NON-NLS-2$ 
properties.put( "osgi.framework.useSystemProperties", "false" ); 
initPropertiesMethod.invoke( null, new Object[]{properties} ); 
} 
else 
{ 
Iterator iter = properties.entrySet( ).iterator( ); 
while ( iter.hasNext( ) ) 
{ 
Map.Entry entry = (Map.Entry) iter.next( ); 
String key = (String) entry.getKey( ); 
String value = (String) entry.getValue( ); 
System.setProperty( key, value ); 
} 
System.setProperty( 
"osgi.framework.useSystemProperties", "true" ); //$NON-NLS-1$ //$NON-NLS-2$ 
} 
 
Method runMethod = clazz.getMethod( 
"startup", new Class[]{String[].class, Runnable.class} ); //$NON-NLS-1$ 
bundleContext = runMethod.invoke( null, new Object[]{new String[]{}, null} ); 
frameworkContextClassLoader = Thread.currentThread( ) 
.getContextClassLoader( ); 
} 
catch ( BirtException be ) 
{ 
throw be; 
} 
catch ( Exception e ) 
{ 
throw new FrameworkException( "Can not start up OSGI - {0}", 
new Object[]{e.getMessage( )}, e ); 
} 
finally 
{ 
Thread.currentThread( ).setContextClassLoader( original ); 
}

Another update ,

The cause for the above exception is the entry in the config.ini file 'eclipse.security=true' . On debugging I found that an attempt is made to load the class 'true' which corresponds to the value of the property eclipse.security . Since this class could not be loaded a classNotFoundException is being thrown and which gets manifested as BIRTException .

If anyone can clarify what should be the exact value of the property eclipse.security?
