System hang after when try to run report from a form

Question

Hi all,
I was able to run the report by using the run_report command from form builder to call a report with any problem. However, when I attached in my application, the form is being call out but when try to click on the print button from the form, the screen is stuck or hung without showing anything.
Below is part of the code that will call the report to print within the form.
declare
     PL_ID PARAMLIST;
     printername VARCHAR2(50);
begin     
     PL_ID := GET_PARAMETER_LIST('WEIGHMENT');
IF NOT ID_NULL(PL_ID) THEN
DESTROY_PARAMETER_LIST(PL_ID);
END IF;
PL_ID := CREATE_PARAMETER_LIST('WEIGHMENT');
printername := '"'||'ZDesigner GK420d, USB001'||'"';
Add_Parameter(pl_id, 'DESNAME', TEXT_PARAMETER, printername);
Add_Parameter(pl_id, 'DESTYPE', TEXT_PARAMETER, 'PRINTER');
RUN_PRODUCT( REPORTS, 'ACT_INV_ITM_LBL.rep', SYNCHRONOUS, RUNTIME, FILESYSTEM, pl_id, NULL );
Thanks.

i got it
just make report out of SSO by the steps
If you don't want to use Single Sign-On:
Edit $ORACLE_HOME\reports\conf\rwservlet.properties
Change #SINGLESIGNON=YES to SINGLESIGNON=NO
Log in to the Enterprise Manager website at http://<server_name>:18100
Navigate to the Report server page. Click on the "Edit Configuration File" link.
Delete the section that reads
<security id="rwSec" class="oracle.reports.server.RWSecurity">
<!--property name="securityUserid" value="%PORTAL_DB_USERNAME%/%PORTAL_DB_PASSWORD%@%PORTAL_DB_TNSNAME%" confidential="yes" encrypted="no"/-->
<property name="oidEntity" value="reportsApp_apps10_85643151B9D911DCAF4E278FF4D47F77"/>
</security>
Press “OK” and let EMWebsite restart the reports server. or restart all
and it will work ...
