Crystal report passing string date parameter to a report from my jsp page


Problem Statement :

Just found out that passing a string attribute from my jsp page to a crystal report is not working and the report was asking for the date parameter again.

Solution :

Thanks to a thread on stackoverflow , the solution was to create date string as

#9/25/2014# and then pass it to crystal report from my page and now it's working fine.

Eclipse saving workbench state hangs

I followed the below instructions in the blog

  • Make a backup of your “.metadata“-folder (very important!!) (this folder inside teh eclipse workbench/workspace folder)
  • navigate into the “.plugins“-folder located inside “.metadata
  • delete the folder “org.eclipse.ui.workbench
  • startup eclipse again and check if there is still everything you need


  • http://blog.elitecoderz.net/repair-eclipse-workbencheclipse-workbench-reparieren/2009/06/comment-page-1/#comment-6693

    and the problem was resolved , now when I close my eclipse it doesn't hang at saving workbench state.

    infact I have noticed that the eclipse is starting a closing faster than before.

    Usefull Oracle Database Queries


    Get the details of important oracle parameters such as "PASSWORD_LOCK_TIME" and "SESSIONS_PER_USER" etc

    select * from dba_profiles order by profiles

    Get the Name of the oracle instance

    SELECT sys_context('USERENV','DB_NAME') AS Instance FROM dual;
    Get the name of the current oracle instance and user id

     select name,user from v$database


    Query to see who has access to your package


    select grantee, table_name, privilege
         from dba_tab_privs
         where
           table_name = 'YOUR_PACKAGE_NAME'

    I will keep adding other usefull queries here....
