Inserting CLOBs into Oracle 9i with JDBC

[fatcodeguy]

Hi,

I have a Java program that populates an Oracle 9i database with CLOBs. When I run the program with just one thread, the program works perfectly. If I try with more than one thread, I get an "Invalid empty lob operation" error for each thread

java.sql.SQLException: Invalid empty lob operation

	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)

	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269)

	at oracle.sql.CLOB.getDBAccess(CLOB.java:1442)

	at oracle.sql.CLOB.putChars(CLOB.java:542)

	at oracle.sql.CLOB.putString(CLOB.java:627)

	at ProcessorThread.addToDatabase(ProcessorThread.java:303)

	at ProcessorThread.processDocument(ProcessorThread.java:233)

	at ProcessorThread.run(ProcessorThread.java:73)

Can anyone help me with this?
Thanks!
