What is the CHKOBJ equivalent in Java?

[J.Pluta]

One way is to call the CHKOBJ command using an CommandCall object. Another is to try the ProgramCall object and write a CL wrapper around the CHKOBJ command. A third technique would be to use the fully qualified pathname of the object (MYFILE in MYLIB is /QSYS.LIB/MYLIB.LIB/MYFILE.FILE) and use the File.exists() method in Java. Joe

You could create an ILE procedure that executes the CHKOBJ command by using QCMDEXC. Then you could put the procedure in a service program and code it as a native method in java. Then you could call the java native method from where ever in you java application that you need to.

Philip, I'm trying to understand your approach as I am also writing other service programs in ILE RPG. Can you please provide me with some sample code so I can put things into perspective? I like the idea of using service programs as native methods in java. I just need some help on how to put this together. Thanks in advance.

I learned this from the book "Java for RPG Programmer's" which can be purchased at this site. Appendix B of the book discusses how to mix RPG with Java. It gives an example of the code you will need in the Appendix. I suggest purchasing or borrowing the book.

How do I check to see if a file exists on the iSeries from a java application? I'm using JT400.jar.

This is starting to look very exciting and powerful! Thanks for the link. For CHKOBJ I ended up using the CommandCall. It was simple and quick for what I was doing, but for other stuff I'll definitely keep this new technique in mind. Necqui
