REP-300 Error while running report using App Server

Question

Hi,
I am currently trying to run a report using the Application Server.
This report is being called from a form.
I am able to connect to the report server and all configurations seems to be correct.
But when I execute the report from the form, I am getting error "Unable to run report"
When I look at the error message in the Report Server queue, I find
"REP-300 Table or View does not exist.."
But that table does exist in the database.
What could be be the problem ?
Please help.
The code in the form that calls the report is
report_id := FIND_REPORT_OBJECT( report_name );
vc_user_name:=get_application_property(username);
vc_user_password:=get_application_property(password);
vc_user_connect:=get_application_property(connect_string);
vc_connect:=vc_user_name||'/'||vc_user_password||'@'||vc_user_connect;
SET_REPORT_OBJECT_PROPERTY(report_id ,REPORT_OTHER, 'paramform=yes     p_user_connect='||vc_connect ||' p_servername=repsrv'||' p_action=<host>/reports/rwservlet?' );
v_rep := RUN_REPORT_OBJECT(report_id, parmlist_id);

The report is working perfectly fine when I run it from the Report Builder. I get the correct output.
I am getting this error when I try to run the report through a Report server.
I run the form from the Forms 10g builder. This form has a button "Run Report". When I click on the button the report is run using the Report server.
This is when I get the error.
There are other forms that are also called via the same form. Those work fine. The only difference between those forms and this one is that this one has user parameters passed to it. This one also has an attached library attached to it.
The code in the Form to call the report is
report_id := FIND_REPORT_OBJECT( report_name );
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_COMM_MODE, SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_EXECUTION_MODE, BATCH);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_DESTYPE, FILE);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_DESFORMAT, 'pdf');
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_SERVER, 'rep-vena01-xp');
v_rep      := RUN_REPORT_OBJECT(report_id, parmlist_id );
v_jobid := substr( v_rep, length( v_reportserver) + 2, length(v_rep) );
v_repstatus := REPORT_OBJECT_STATUS( v_rep );
IF ( v_repstatus = 'FINISHED' ) THEN
v_url := '/reports/rwservlet/getjobid' || v_jobid || '?server=' || v_reportserver ;
web.show_document( v_url, '_BLANK' );
END IF;
