Now you have a project created with an empty class so it’s time to complete the source code and we use the NX Journal Recording.

If we want to debug a single class only, we could use the compiled Java class file which can be found automatically after saving the Java source file in workspace\projectname\bin\packagename\class .& W: L: |$ e- F% D
Due to Java naming convention and limitations we don’t want to have multiple classes in one file so in that case we would use the final JAR archive file.9 [+ M) Y2 D) ?' Y
In order to connect to the NX session, NX needs to start the JVM (Java Virtual Machine) along with some debug settings, for example the communication port between NX and Eclipse.
- d& ` @6 x5 P, A2 V1 E) w" aFrom a NX8 command prompt, we enter the following commands:
5 b) \, U( I. u M) G$ g5 I* q( t: Z# y" b6 @2 r' D

Any simple class will do the job, for example a famous HelloWorld class.
