All,
My web application uses Weblogic connection pool for database activities.
I am using Oracle database.


I have java class file which has the following piece of code, which my application uses

oracle.sql.CLOB clob = (oracle.sql.CLOB)rs.getClob(columnNumber);

and I don't want to change the above line. But when I run the application, it gives me below error...

   1. SEVERE: Standard exception info for exception of type: 'java.lang.ClassCastException' at level: 0 - Error Text: 'weblogic.jdbc.wrapper.Clob_oracle_sql_CLOB'  
   2. Apr 3, 2008 10:19:33 AM com.agencyport.menu.MenuController insert  
   3. SEVERE: java.lang.ClassCastException: weblogic.jdbc.wrapper.Clob_oracle_sql_CLOB  
   4.    
   5.         at com.agencyport.database.OracleDatabaseAgent.updateLOB(OracleDatabaseA  
   6. gent.java:111)  
   7.         at com.agencyport.menu.MenuController.insert(MenuController.java:815)  



It seems like Weblogic returns the object 'weblogic.jdbc.wrapper.Clob_oracle_sql_CLOB', rather than the 'oracle.sql.CLOB' which i am expecting.

Is there any way i can force the weblogic to return the object i am expecting,
since i can't modify the above piece of code, in which case, i can cast it to 'weblogic.jdbc.wrapper.Clob_oracle_sql_CLOB'.

Any help will be highly appreciated....

This is NOT a solution!  HOW did you change your code?
