NameNotFound exception by using javax.jts.UserTransaction

Question

Hello:
          I am working on using jts for the transaction access to a Oracle 7.3
          database.
          In the property file of my application, I used
          weblogic.jdbc.connectionPool.oraclePool=\
          url=jdbc:oracle:thin:@10.10.0.201:1521:orcl,\
          driver=oracle.jdbc.driver.OracleDriver,\
          loginDelaySecs=1,\
          initialCapacity=4,\
          maxCapacity=10,\
          capacityIncrement=2,\
          allowShrinking=true,\
          shrinkPeriodMins=15,\
          refreshMinutes=10,\
          testTable=dual,\
          props=user=joe;password=tiger
          weblogic.allow.reserve.weblogic.jdbc.connectionPool.oraclePool=guest
          weblogic.jdbc.TXDataSource.weblogic.jdbc.jts.jtsPool=oraclePool
          In my servlet, I used
          Context ctx = null;
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
          env.put(Context.PROVIDER_URL, "t3://127.0.0.1:8080");
          env.put(Context.SECURITY_PRINCIPAL, "system");
          env.put(Context.SECURITY_CREDENTIALS, "Administrator");
          ctx = new InitialContext(env);
          UserTransaction tx = (UserTransaction)
          ctx.lookup("javax.jts.UserTransaction");
          When I access the servlet, the following exception were thrown.
          javax.naming.NameNotFoundException: 'javax.jts.UserTransaction';
          remaining name 'jts.UserTransaction' at
          weblogic.jndi.toolkit.BasicWLContext.resolveName(BasicWLContext.java,
          Compiled Code)at
          weblogic.jndi.toolkit.BasicWLContext.lookup(BasicWLContext.java:133)at
          weblogic.jndi.toolkit.BasicWLContext.lookup(BasicWLContext.java:574)at
          javax.naming.InitialContext.lookup(InitialContext.java:349) at
          jtsdemo.SelectAccessor.accessDatabase(SelectAccessor.java:20)at
          jtsdemo.SelectJTS.doPost(SelectJTS.java:29) at
          jtsdemo.SelectJTS.doGet(SelectJTS.java:12)
          When I open the weblogic console, in directory Naming, I could not find
          javax.jts.UserTransaction entry. However there is weblogic.jdbc.jts
          entry which is generated by the following line, which I put into the
          properties file.
          weblogic.jdbc.TXDataSource.weblogic.jdbc.jts.jtsPool=oraclePool
          Thank you for any thoughts.

Answer 1

Hello:
          Thank Kumar for a reply.
          I checked the document and able to follow it and use
          javax.sql.DataSource to get a jts connection and select from database.
          In the properties file of the weblogic application server,
          weblogic.jdbc.TXDataSource.jtsOraclePool=oraclePool
          Some questions follow.
          In this way, I could not get a handle to UserTransaction. I am
          wondering in case of database insertion, does this connection
          automatically commit for each execUpdate(), if I do not call
          conn.setAutoCommit(false)?
          If a programmer has to manage the transaction on the Connection,
          what is the advantage to use jts connection pool? Does this performed
          faster or internally it behaves the same?
          Look forward to any insight.
