    How to use jboss jndi from a java application

    peterdnight
    peterdnight Mar 5, 2003 10:40 PM

      Hi,

      I defined a mysql-service.xml file, and can access it from within the jboss servlet container via a JSP. Same code placed in an application program (classpath set to pick up jnet.jar and jbossall-client.jar) yields a naming exception every time. The pertinent code is shown below.

      Does ANYBODY know why I can get a JNDI reference inside of the JBOSS JVM, but not outside....I am very suspicious of the login-config code... what the heck is the principal attribute? I guessed that it was DB name, but I am thinking it has to do with security....

      Thanks,
      Peter

      ---> login-config.xml snip...
      <application-policy name = "MySqlDbRealm">

      <login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" flag = "required">
      <module-option name = "principal">SmalleB</module-option>
      <module-option name = "userName">myUser</module-option>
      <module-option name = "password">myPass</module-option>
      <module-option name = "managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=PeterSqlDS</module-option>
      </login-module>

      </application-policy>

      ====> Lookup code works in JSP, fails in APP...
      InitialContext ic = new InitialContext();
      System.out.println("Got an InitialContext");

      DataSource ds = (DataSource) ic.lookup("java:/jdbc/smallb") ;
      System.out.println("Got an datasource");

          if you are outside JBoss' JVM then ic = new InitialContext() will not do the job. Set a hashtable of properties, in particular the jndi provider when you construct your context. You can also provide a jndi.properties to your app. There are several examples throughout the forums or faqs.

            I not looked on the other parts, but regardless of
            how well they work the above will not work outside of the JBoss Server. Anything below the java: namespace is anly acceccible inside JBoss. (In particular, this means that you cannot access DataSources from outside since they always will be in the java: namespace, which differs from for example weblogic).

            If you are only testing JNDI access then you should try to look up an EJB or someting. If you want a DataSource I guess you are out of luck :-)

              Many thanks for the suggestion, I apologize for not mentioning that i do have a jndi.properties (Shown below)

              It is being read successfully because if I change the port to 1098, I get the expected exception thrown..

              Other guesses;) I did grab the 3.0.6 source last night and took a look at the test code in the jndi package..I copied the showTree code. I confirmed that NONE of the java: context is visible, including my datasource... the output is below the properties...
              Help;)
