Hi, I am Abhilash A newbee for FlexFramework and LiveCycle Data Services. I tried to connect to a java class Hello through RemoteObject.

I have compiled the Hello.java file with this version of java. If this is not the required version. Which version should I use?
You have compiled and deployed your destination source code (Hello class) with JDK 1.6, whereas your Tomcat server is running with JDK 1.5.0_14. Try compiling the destination source code with JDK 1.5 and then run the example.
