Hi,

I have no idea, but you may want to try both the portal and portlet
in one container and deploy OGSA-DAI to a separate container to be sure
there are no jar conflicts or something like that.

Dear all,
I'm trying to developm ogsa-dai portlet on Grisphere.
I have basic HelloWorld portlet and java program which accesses
OGSA-DAI data sources. They both are working but when I try to add
interaction with OGSA-DAI to portlet. It stops working without any
warnings, errors or messages. I have enabled logging but it did not help.
Can anyone suggest me the way to look for solution.
Here is my portlet source
Under portlet source just in case I'm posting java program source
which works perfectly well
I spent quite a lot of trying to figure out what is going on so ANY
HELP WOULD BE MUCH APPRECIATED.
THANK YOU.
