I recently installed oracle 11g R2 on a windows 2003 server, I migrated a 10g ( database into 11g successfully. However when I tried to install the corresponding application, I get the following message:

"Could not find oracle jdbc library ( classes12.jar or nls_charset12.jar) in C:\oracle11\product\11.2.0\dbhome_1\jdbc\lib. Check whether the Oracle component is correctly installed".

Could someone please advise how tis matter can be solved?? Is there a possibility the application is not supported in oracle 11g??

Download the classes12.jar file and put it in the Java CLASSPATH of the application.

Whether "the application" is supported with Oracle 11 depends on "the application". I can't think of any reason why there should be a problem with the JDBC connection itself or with most standard SQL or PL/SQL, but it *might* be that somewhere in the SQL the application issues is a problem somewhere.
