 Here is my code:
AS400 system = new AS400("MRCBOX");
QSYSObjectPathName path = new QSYSObjectPathName("QSYS.LIB", "BRUCELIB.LIB", 
"TESTARA.DTAARA");
CharacterDataArea dataArea = new CharacterDataArea(system, path.getPath());

 It produces this error:

com.ibm.as400.access.ExtendedIllegalArgumentException: object(BRUCELIB.LIB): 
Length is not valid.

com.ibm.as400.access.QSYSObjectPathName.<init>(QSYSObjectPathName.java:263)

Thanks.
