Technote (FAQ)


Question

What EJB converter should you use if you have a BLOB column?

Answer

You need to use the VapUnicodeStreamToStringConverter for a Binary Large Object (BLOB) column.

Here are the steps to add the converter to your EJB-RDB mapping:

  1. Go to the J2EE perspective and open the Map.mapxmi file that is located in the database backends folder; you will see the mapping editor.

  2. In the Overview view, choose the column with BLOB type in the Enterprise Beans Column.

  3. In the Properties View, go to Properties Tab.

  4. Change the Transformation value to VapUnicodeStreamToStringConverter.

  5. Save the file.
