Debugging Java

When message flow processing has paused at a breakpoint that you have set in source code within a node that contains Java™ code, you can examine and modify the Java variables in the Flow Debugger.

1. To open the Command Console, click Start > All Programs > IBM App Connect Enterprise 13.0.n > IBM App Connect Enterprise Console 13.0.n.
2. Start the integration node by running the mqsistart command in the Command Console.
3. Check that the Java debug port is set by running the mqsireportproperties command (all on one line) in the Command Console:

   mqsireportproperties integrationNodeName -e integrationServerName -o ComIbmJVMManager -r

   For example:

   mqsireportproperties TEST -e default -o ComIbmJVMManager -r

4. Set the Java debug port by running the mqsichangeproperties command (all on one line) in the Command Console:

   mqsichangeproperties integrationNodeName -e integrationServerName 
   -o ComIbmJVMManager -n jvmDebugPort -v port_number

   For example:

   mqsichangeproperties TEST -e default 
   -o ComIbmJVMManager -n jvmDebugPort -v 3920

5. Stop and restart the integration node by running the mqsistop and mqsistart commands.
6. Open the message flow that you want to debug in the Message Flow editor by double-clicking its name in the Application Development view.
7. Add a breakpoint where the Java method is called, by following the instructions in Adding breakpoints in the flow debugger.
8. To step directly into the Java code during the debugging process, add a breakpoint in the Java code.
9. Deploy the BAR file that includes the JAR file that contains the Java code, by following the instructions in Deploying integration solutions to a production environment.
10. Click Run > Debug to open the Debug wizard.
11. Right-click Debug in the list of elements on the left and click New.
12. Set the Java Debug Port with the same value that you specified for the -v parameter on the mqsichangeproperties command, and click Apply to save your changes.
13. Click the Source tab, specify the source file location, and click Apply to save your changes.
14. Click Debug to start the debug process.
