### Oracle stored procedure UDS

Due to the unique nature of Oracle stored procedures, you cannot add them directly into a JReport catalog. In this sense, the usage of JReport Designer is limited when you use an Oracle database. As a substitute, JReport has developed the user data source API which can use stored procedures in Oracle. The class is named OracleProcedureUDS, in the package jet.datasource.oracle.

Pick a task from the following:

- The UDS class
- Adding an Oracle stored procedure
- Troubleshooting
