Cannot use jdk 6 function when using a blackberry project...

Question

I use Eclipse 3.4.2 to build my Blackberry project. I create a blackberry project...So inside, I have the "net rim" blackberry library, and inside this library I have a bunch of jdk function...like java.lang, or java.io...
Before installing Eclipse, I have installed JDK 6 to work with and I'm actually trying to use those library.
When I include JDK libraries in my blackberry project, I can import everything from the JDK, BUT I cannot use any class imported with the "import" tag...
NOTE: net_rim_api.jar contains "java.lang.String" and JDK 6 also. I want to use the split() and substring() function inside the String class contained inside JDK 6, but it seems that eclipse only see the String class contained inside net_rim_api.jar...
My question is:
Why can I import my jdk objects, and can't I use the class corresponding to them?
If I create a projet a standard Java Project, and I include my blackberry library it pop me an error...

All I want is to use java.lang.String with its split() and substring() function which are not inside the blackberry java.lang.String library...
any idea?

Answer 1

The function module has only one input parameter, which should be a string with length less than 256. (I tried many predefined data element like RPLM_STRING, but when I tried to add the function module as a method of BAPI, the SAP always gave me the error: data type xxxxx cannot be used for methods)
It only has one output parameter: RETURN (associated type: BAPIRETURN)
I am really not familiar with ABAP program, let alone BAPIs. Any suggestions would be very helpful to me. I sincerely appreciate your help.
