XMLType and JPublisher

Question

Hi, I'm trying to use a table with a XMLType column in combination with Java classes generated by JPublisher.
Table:
CREATE TABLE TEST_XML_TAB (
     TESTID           NUMBER(10),
     FILENAME      CHAR(127) UNIQUE,
     TESTDOC      SYS.XMLTYPE,
CONSTRAINT TESTID_PK PRIMARY KEY(TESTID))
XMLTYPE COLUMN TESTDOC XMLSCHEMA "http://xxx/METADATA"
ELEMENT "Metadata";
There seems to be no problem materializing data into a generated class:
orset = (OracleResultSet)stmt.executeQuery("select x.FILENAME, x.TESTDOC.xmldata from TEST_XML_TAB x");
Metadata meta = (Metadata)orset.getORAData(2, Metadata.getORADataFactory());
But I can't find an easy way to make an insert or update!
Any Help?
Thanks!

Answer 1

OK, I tried building an object view around the table:
CREATE TYPE TEST_XML_TAB_TYPE AS OBJECT (
     TESTID           NUMBER(10),
     FILENAME      CHAR(127),
     TESTDOC DD."Metadata_T"
CREATE VIEW TEST_XML_TAB_VIEW OF TEST_XML_TAB_TYPE
WITH OBJECT IDENTIFIER (TESTID) AS
SELECT e.TESTID, e.FILENAME, e.TESTDOC.xmldata
FROM TEST_XML_TAB e;
Then the following works fine:
opstmt = (OraclePreparedStatement) conn.prepareStatement(
"insert into TEST_XML_TAB_VIEW (TESTID, FILENAME, TESTDOC) values(?,?,?)");
opstmt.setORAData(3, meta);
Using SQL*Plus Worksheet the statement
SELECT TESTDOC FROM TEST_XML_TAB;
shows all inserted data sets.
But selecting the data sets by using Java and XMLType the inserted data sets couldn't be streamed out.
Which information is lost when inserting as described above?
Any Help?
Thanks!
