Hi all,
I'm writing to dev list instead of user list.
In my opinion, it doesn't seem to have null name parameter in getAttribute()
method.
According to Raman's stack trace and the related sources,
InformationProviderServiceImpl class
calls
ServletRequestImpl's getAttribute() with a literal parameter,
"org.apache.jetspeed.engine.core.DynamicInformationProvider".
Therefore, I think we can add a workaround code for WebSphere here in
InformationProviderServiceImpl.java to just ignore NullPointerException like
the following:
public DynamicInformationProvider
getDynamicProvider(javax.servlet.http.HttpServletRequest
request)
{
DynamicInformationProvider provider = null;
try
{
provider = (DynamicInformationProvider)
request.getAttribute("org.apache.jetspeed.engine.core.DynamicInformationProvider");
}
catch (Exception e)
{
// some problem in WebSphere??
}
if (provider == null)
{
provider = new DynamicInformationProviderImpl(request,
servletConfig);
request.setAttribute("org.apache.jetspeed.engine.core.DynamicInformationProvider",
provider);
}
return provider;
}
I think it would be possible to meet another exception after the try catch
block, but I cannot
test with WebSphere 6 now.
Raman, would you test if the try catch block could be a workaround? And please
let us know.
Thanks.
Regards,
Woonsan
