  Simplify use of Java Platform Debugger Architecture to debug remote Java programs

Typically developers of RPG/COBOL programs familiar with use of green-screens face significant hurdles when moving to a web-based Java Development Platform.

The Eclipse Integrated Development Environment (IDE) provides a generic way to debug remote Java programs. However, IDE requires several cumbersome interrelated steps and there is a need to replace these with one step.

Java Platform Debugger Architecture (JPDA) is supported by the Eclipse based IDE.

Eclipse based IDE implements Java Debug Interface ( JDI ). Users can connect to, and debug any remote application running on a remote Java Virtual Machine Debugger Interface ( JVMDI ) which is compliant with VM through IDE. However the generic way to use JDI is cumbersome for typical iSeries legacy program developers. The typical scenario includes the steps of: Go to iSeries "green-screen" to start class in remote VM. Java Debug Wire Protocol (JDWP) port and tedious options must be specified. This causes execution of the program to halt until a connection is established with debug client on this port. IDE debugger client is then started which tries to connect to the above specified port.

Once a connection is sensed, the remote class starts to run until a breakpoint is hit, or the program terminates.

The disclosed idea effectively automates the whole process described above. The debugging of remote Java program on iSeries from IDE is...
