I am using Jboss 4.0.4 GA,JDK1.5.0_01. My database is informix.
When I use JTA in Tomcat,it always failed,please help me,Thanks!
My code is:
String ls_sql=null;
Context ctx=null;
UserTransaction ut=null;
Connection conn=null;
Connection conn1=null;
try{
ctx = new InitialContext();
ut=(UserTransaction)ctx.lookup("java:/comp/UserTransaction");
ut.begin();

DataSource ds = (DataSource) ctx.lookup"java:/comp/env/jdbc/szjdcdb");
ls_sql=" update y_user set username='yzs' where usercode='001'";
conn=ds.getConnection();
Statement stmt=conn.createStatement();
stmt.execute(ls_sql);
stmt.close();


DataSource ds1 = (DataSource) ctx.lookup("java:/comp/env/jdbc/szxmgl");
ls_sql=" update y_user set username='yzs' where usercode='001'";
conn1=ds.getConnection();
Statement stmt1=conn.createStatement();
stmt1.execute(ls_sql);
stmt1.close();

request.setAttribute("sql","ok");


ut.commit();


}catch(Exception e){
ut.rollback();
request.setAttribute("error",e.toString());
request.setAttribute("sql",ls_sql);
return mapping.findForward("failed");
}finally{

conn.close();
conn1.close();
}

Jboss didn't report errors,but table is locked,Why ?
