    about com-bridge

    IPOz Newbie

      hi,friends
      Recently i evaluated sun's com-bridge which will be used to
      access EJB from windows.The com-bridge has supplied enterprise service dll for the following ejb container:
      .Planets IAS 6.0
      .Sun Microsystems J2EE 1.2.1+ RI
      .SilverStream 3.7
      .Weblogic 5.1,Weblogic 6.0
      .WebSphere 3.5

      but there is no such a dll for JBoss.Of course it is NOT very
      difficult for use to write one however we still want to know whether there already is any.


      Any suggestion is appreciated!

          By searching this forum,i get the the service dll from http://laurent.etiemble.free.fr/combridge/.
          In order to test it i have deployed a session bean named BankBean.Now i can get the home in delphi however i always can NOT create the sessin bean - java.lang.IllegalAccessExceptio.
          //*************** codesnippet ***************
          procedure TForm1.ejbClick(Sender: TObject);
          var
          home : com_kf_ejb_interfaces_BankHome;
          bean : com_kf_ejb_interfaces_Bank;
          begin
          JvmControl1.Classpath := 'd:\allen\jboss\client\jnp-client.jar;' +
          'd:\allen\jboss\client\jboss-client.jar;' +
          'd:\allen\jboss\client\jboss-j2ee.jar;' +
          'd:\allen\jboss\client\jaas.jar;' +
          'd:\allen\jboss\client\jbosssx-client.jar;' +
          'd:\allen\cas\test\stub\bank.jar' ;
          JvmControl1.StartJvm;
          JBossServices1.ProviderURL := 'jnp://192.168.1.118:1099';

          home := com_kf_ejb_interfaces_BankHome(
          JBossServices1.LookupEjbHome(
          'bank/BankBean',
          'com.kf.ejb.interfaces.BankHome')
          );
          showMessage('Found bank home'); <====ok

          bean := com_kf_ejb_interfaces_Bank(home.create()); <=== raise exception here.
          showMessage('Created Bank');

          showMessage(bean.getXml());
          bean.remove();
          end;

          please shed light on me !

              com-bridge is not a good product and it progresses slowly :(

              Up to now i cannot use it to call ejb on jboss.Moreover i even can not use it to call local class of my own !!!
              Here is a simple class named BankClient:

              package com.kf.ejb.test;

              public class BankClient
              {
              public static String getXml()
              {
              String xml = "Welcome you,dear CAS :)";
              return xml;
              }
              }
              it will be jared into bank.jar.

              procedure TForm1.staticMethodClick(Sender: TObject);
              var
              SystemStatics,bank : OleVariant;
              begin
              JvmControl1.Classpath :=
              'd:\allen\myProject\cas\ejb\build\bank.jar' ;

              JvmControl1.StartJvm;

              SystemStatics := JavaServices1.GetJavaStaticsFor('java.lang.System');
              showMessage(SystemStatics.currentTimeMillis); <===good

              bank := JavaServices1.GetJavaStaticsFor('com.kf.ejb.test.BankClient');
              showMessage(bank.getXml()); <= raise error:"Unsupported type : cannot convert to Jobject : VT_ERROR"
              end;


              I am so disappointed about com-bridge :(
