Problem using OsgiBundleXmlWebApplicationContext with Websphere 7

[Deepak]

Hi,
I am trying to use Spring DM within hte new IBM Websphere 7 environment along with the featurepack for OSGi. I am able to deploy my spring based web application within the OSGi env using the SpringFW jar bundles along with the dependency bundles.
I want to use the spring DM based jar bundles also within my application and try to access the OSGi services using the declarative syntax. To do this I had include the spring dm bundles - minus the web extender bundle since its not required within thewebsphere environment. Also I made the change to the web xml to add the context param and listener.

<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.osgi.web.context.support .OsgiBundleXmlWebApplicationContext</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoade rListener</listener-class>
</listener>

But when I try to deply this web bundle, I get the error
"bundle context should be set before refreshing the application context"

Looks like the bundle context is not being set even when the WAR is a WEB bundle. When checked on the IBM forums they said that
"Access to the BundleContext from inside a WAB is as per section 128.6.1 of the OSGi 4.2 Enterprise Specification:

BundleContext ctxt = (BundleContext) servletContext.getAttribute("osgi-bundlecontext");
"

Can you let know why I am getting this error.
Thanks.

Below is the stack trace if it helps.

FYI
I am using the Spring DM 2.0.0.M1 release version.

I think I have found a problem in the Spring DM bundle
spring-osgi-web-2.0.0.M1.jar

class: OsgiBundleXmlWebApplicationContext.java

This class is gets the bundle context from the servlet context and is looking for the following attribute name
BUNDLE_CONTEXT_ATTRIBUTE = "org.springframework.osgi.web."
+ BundleContext.class.getName();

Since Spring DM version 2.0.0.M1 is supposed to also support blueprint standards, it should be additionally looking for the attribute name "osgi-bundlecontext" in the servlet context.

I have temporarily overcome this problem by creating a fragment bundle containing my own class thats extending the above OsgiBundleXmlWebApplicationContext class and using the same which uses the standard attribute name.

I think this needs to be fixed in the regular Spring DM release.
