我的代码是

XMLType poxml = null;
String dataElXml= null;

try{
Context ctx= new InitialContext();
DataSource ds=(DataSource)ctx.lookup(dsource);
Connection Conn=ds.getConnection();
Statement Stmt=Conn.createStatement(); 
String itemID=request.getParameter("cat");
ResultSet rs=Stmt.executeQuery("SELECT TA.COLUMNNAME.extract('/data-pac/data-e')  FROM Tablename TA WHERE ID = "+itemID+"");

Integer j=0;

while(rs.next()) {
ok = true;
poxml = (XMLType)rs.getObject(1);
