Encountered a Oracle exception due to unique constraint violation. Corrected the sequence to solve the problem but the server logs still keep showing the same exception and exception still keeps occuring. If I to insert records into the same table using sql prompt it works but via the application using the same sql it does not work. Is there a caching of sql exception in the server . Weblogic is using JDBC connection pool for connection pool. What could be the cause of this error and what is the solution?
