SQLException: After clearParameters() has been called, all parameters must be reset before executing

Question

Hi,
I am running: Weblogic 6.1, SP2
Driver : weblogic.jdbc.oci.Driver
Reason for not using the "thin" driver, which works, is limit
on size of Clob
Previous references to this problem in this newsgroup indicate driver problems
with older versions of WL.. I am using the latest..
The SQLException I get is "After clearParameters() has been called, all parameters
must be reset before executing". This happens the second time the code below is
excuted ( ok the first time )
"clearParameters()" is never called explicitly in my code.
The exception occurs on the "spFunc.execute();" statement at the very end of this
code:
// OBS:connection, conn_, is opened from a connection pool
before this code is called and cloesed afterwards.
conn_.setAutoCommit(false);
// ============== Initializing clob ==================
SerialStatement stmt = (SerialStatement)conn_.createStatement();
stmt.execute("INSERT INTO lc_clob_temp VALUES (1, EMPTY_CLOB())");
// OBS: using a prepared statement here will result in SerialClob
// exception when using setClob in the prepared statement
below
// This is probably a bug ( worked in WL 5.1 ). We had this
as a support case 270952 with WebLogic.
stmt.execute("SELECT * FROM lc_clob_temp WHERE id = 1");
ResultSet crs = stmt.getResultSet();
weblogic.jdbc.rmi.SerialClob xmlClob = null;
while ( crs.next() ) {
xmlClob=(weblogic.jdbc.rmi.SerialClob)crs.getClob("newclob");
// Call Oracle's stored procedure for calling Oracle XSU.
SerialCallableStatement spFunc =
(SerialCallableStatement)conn_.prepareCall(
"declare " +
"insCtx sys.DBMS_XMLSave.ctxType; " +
"begin " +
"insCtx := sys.DBMS_XMLSave.newContext(?); " +
     "sys.DBMS_XMLSave.setBatchSize(insCtx,0);" +      "sys.DBMS_XMLSave.setCommitBatch(insCtx,
0);" +
"? := sys.DBMS_XMLSave.insertXML(insCtx,?); " +
"sys.DBMS_XMLSave.closeContext(insCtx); " +
"end;"
spFunc.setString(1, viewName );
spFunc.registerOutParameter (2, Types.NUMERIC);
Writer outstream = xmlClob.getCharacterOutputStream();
outstream.write(xml.toString());
outstream.flush();
outstream.close();
spFunc.setClob( 3, xmlClob);
spFunc.execute();
spFunc.close();
