How to update binary resource from java?

Question

Oracle 9i release 2 xmldb
What is the recommended way to update the contents of a binary resource via JDBC. Pointers to documentation would be very helpful. The XML DB User's Guide doesn't say much about binary resources, except for using WebDAV and FTP.
The following executed normally but the database isn't affected.
try
conn = _project.getConnectionManager().getConnection();
conn.setAutoCommit (false);
stmt = conn.prepareStatement (
"SELECT XDBUriType(?).getBlob() FROM PATH_VIEW WHERE PATH = ?"
stmt.setString(1, _path);
stmt.setString(2, _path);
rset = stmt.executeQuery();
rset.next();
BLOB blob = ((OracleResultSet)rset).getBLOB(1);
if (blob != null)
OutputStream out = blob.getBinaryOutputStream();
byte[] bytes = contents.getBytes();
out.write(bytes);
out.flush();
out.close();
else
System.out.println("blob = null");
conn.commit();
conn.close();
catch (java.sql.SQLException e)
e.printStackTrace();

Hi pooja123
We have the code to append resource name "WriteBack" to the waveset.resources property, we can actually read the value from <ref>accounts[WriteBack].something<ref>. But we just can't write anything back.
I heard from someone that there are not way to write back anything to resource from wrokflow. So I create an Java Clss to do the writeBack.
