I'm migrating my Java EE application from Java 1.4 to Java 6 and moving from OC4J to WebLogic 10.3.3. I'm running into a problem with a stored procedure call that worked in Java 1.4 on OC4J, but is no longer working in Java 6 on WebLogic. The stored procedure definition looks like:
create or replace procedure sp_report
(
/* snip 68 parameters */
rs OUT pkg_recordset.rs_ref_cursor
)
AS ...
Where rs_ref_cursor is:
type rs_ref_cursor is Ref CURSOR;
My java code looks like this:
public final static String CALL_REPORT = "{call SP_REPORT"
+ "(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,"
+ "?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}";
...
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:thin:@[server]:[port]:[sid]", "[username]", "[password]");
cstmt = conn.prepareCall(CALL_ALPHA_REPORT);
/* set 68 other parameters */
cstmt.registerOutParameter("rs", OracleTypes.CURSOR);
...
This always results in this exception on the call to registerOutParameter:
SQL Exception: 17004: Invalid column type: 246

A few things I've tried that all result in the same error:
Thanks for any help.
I found the solution.
Short version: don't enable fast-swap in weblogic.xml
Longer version: enabling fast swap screws up how ints work, so instead of the value of OracleTypes.CURSOR being -10, it was actually 246.
I was having the exact same problem as this guy: https://forums.oracle.com/forums/thread.jspa?threadID=1104780
