[Pljava-dev] Passing custom java object to PL/Java

Is it possible to pass custom Java objects to PL/Java (the reverse of
passing from PL/Java to client programs? The error I get seems to
indicate that the custom data type I defined in the deployment
descriptor is not recognised when I do the setType on PGobject.

I tried to do so as shown in the following files:

http://www.rakeshv.org/tmp/test.java - wrapper program that does the
JDBC invocation from client code.

http://www.rakeshv.org/tmp/RecurrenceTest.java - The PL/Java utility
class

http://www.rakeshv.org/tmp/Recurrence.java - The custom data that is
passed from client to server.

http://www.rakeshv.org/tmp/DeploymentDescriptor.ddr - The deployment
descriptor

The following is the stack trace from the program:

org.postgresql.util.PSQLException: Unknown type testType.
