Hibernate and DB2 data fetching

I am using struts and hibernate application. I have a problem while fetching records from DB2 via hibernate.

I am getting this error

Error code 42704 means that tableName table does not exist. But it exists in the database.

Any idea what could be the problem? Problem with schema or anything else?

Problem is with database schema.

i was using

schema.tableName

when I use

schema1.tableName

it works. Because in DB schema was schema1.
