Hi, everyone.

Thank you for interesting in my question, I think you can help me out from this little problem.

I am using Flex builder 3, BlazeDS, and Java with Spring and Hibernate framework. I using the remote object to load a string from spring's configuration files. But in testing, I found this fault event like this:

RPC Fault faultString="java.lang.NullPointerException" faultCode="Server.Processing" faultDetail="null"

I have check the configuration in remote-config.xml and services-config.xml. But it looks good. There is some people talked about this problem around the internet and I think you can help me and them.

I am using these environment:

• Flex Builder 3
• BlazeDS 3.2.0
• JBoss server
