Hola Roberto
many thank for your answer.
the oracle aplication is developed in Forms [32 bits] Versión 10.1.2.3.0 (Producción)
the server is
10g Release 2 (10.1.2) Patch Set 3 (10.1.2.3.0) for Solaris Operating System
the jsp is in a was server it is version 6 the java aplication is developes using jdk 1.4 but is running on a jre 1.6.0_11
bouth applications have the same ip differt ports
when oracle app calls the java app use the
http://999.999.999.9/dir/dir.do?parameters.....
the port is not especified but is different
when the java application calls the oracle aplication the url is something like
http://999.999.999.9:8888/forms/frmservlet?config=oracle_aplication&otherparams=
if the urls are call directily from a browser they work fine.
has it got something to do with the configuration of the single sing on ??
any help or idea will be very apreciated
many many thanks
