Calling RFC with webdynpro java (in NetWaver Dev.Studio)

Hi,

I have a RFC like below

FUNCTION ZSAP_X.

*"----

*""Local interface:*

*" IMPORTING

*" VALUE(USNAM) TYPE USERNAME

*" EXPORTING

*" VALUE(PWD) TYPE CHAR8

1-I want to write webdynpro java application to call RFC

2-Call RFC with USNAM parameter

3-Get PWD output parameter and write it's value into View TextInput field.

I wrote application but I did not get PWD (output parameter) value. I checked RFC running poreperly.I did not achieve to get PWD.

How can I do that?

Thanks.
