APEX to EBS(R12.1.3) integration, Error while validating ICX session

Question

Hi,
We have successfully integrated APEX page into EBS, i.e. we are able to invoke the APEX page from EBS Responsibility/Menu.
for APEX integration, we have installed APEX on separate OHS on the same server as EBS (and same domain) and in the Form Function HTML call we are using "GWY.jsp?targetAppType=APEX&p=160:10::" to invoke the APEX page.
Issue is, the APEX page displays error "ORA-06502: PL/SQL: numeric or value error: character string buffer too small", which we are not able to capture or supress.
but the page functions as expected and insert/update of tables working fine, in short everything is as expected except that error message.
In Before Header we are calling a custom procedure, which invokes "wfa_sec.getsession( l_username);" to validate the ICX session, this is raising the error.
when i try call "ICX_SEC.getsessioncookie" before the above procedure, it returns valid Session ID and call to "ICX_SEC.check_session" returns VALID; i am not sure why it is throwing error to validate an available Valid session?
All we want is to use the same ICX session in APEX page without need to pass the User name/password or re-login in APEX or set the User/Responsibility context again.
any help would be appriciated.
Rgds,

Try changing your target to:
GWY.jsp?targetAppType=APEX&p=160:10:::Yeswhich will enable debugging when launched.
Are you selecting information from icx_sessions into some variables (user_id, responsibility_id etc) for use in the VPD?
There isn't really any need to "wfa_sec.getsession( l_username);" - the following query should give you everything you need for an EBS context:
SELECT  s.user_id,
        s.responsibility_id,
        s.responsibility_application_id,
        s.security_group_id,
        u.user_name
  FROM  icx_sessions s,
        fnd_user u
WHERE  u.user_id = s.user_id
    AND s.session_id = icx_sec.getsessioncookie
    AND s.last_connect + NUMTODSINTERVAL( time_out, 'MINUTE') > SYSDATE;Select those into some protected application variables and then use fnd_global.apps_initialize() in the "initialization pl/sql code" section of APEX (VPD).
Then if you need anything in your application, you can use the variables in fnd_global (or the application items of course).
