JNDI lookup in Static initializer

Hi,
Is there a problem looking up home interfaces in a static initializer in
WL6.1?
I have a class X which runs in my application client. It has a static
initializer that looks up a home interface. The call to Context.lookup()
times out with weblogic.rjvm.PeerGoneException: No message was received for:
'240' seconds.
The strange thing is, if I force the static initializer to run myself (by
instantiating X directly), then it runs ok. I only get the above problem if
the VM causes it to run (by loading a class Y that references X).
Also, this behaviour is only apparent in the client. In the app server, X
behaves correctly. I'm passing in JNDI properties as system properties on
the command line to the client.
Any help appreciated.
Cheers,
Manish

Check the class loader and thread dump during the place where it works and
the one where it doesn't ... that could help track down why it works that
way.

    Okay "damorgan", you seem to have me confused with a newbie. All I'm posting is the info that I got from my Sys Admin on the fix to my problem I encountered when trying to install Oracle 11g (11.2.0.0) on Red Hat Linux Enterprise 5. Since we're mouting onto an NFS, these are the steps he took. I'm not trying to "hide" information or post as little as possible. What other info do you want? I don't know what you are referring to when you mention "Filer, make, model, software version"? Please elaborate. I was just trying to post to others that may have encountered this problem, and I get somewhat attacked by you. I don't assume anyone can read my mind (especially you).

  • EJB 3.0 and jndi lookup (simple question)

    hi all,
    i am newbie on Weblogic Application Server and i have some issues,
    i have weblogic application server 10.0, also i have oracle timesten in-memory database, i have configured datasource and deploy my ejb 3.0 application, but i could not done jndi lookup?
    here is my example:
    1. one stateless session bean :
    import javax.ejb.Remote;
    @Remote
    public interface InsertSubscriber {
         public void insertSubscriber(SubscriberT subscriberT);
    } 2. here is it's implementation :
    @Remote(InsertSubscriber.class)
    @Stateless
    public class InsertSubscriberBean implements InsertSubscriber {
         @PersistenceContext(unitName = "TimesTenDS")
         private EntityManager oracleManager;
         public void insertSubscriber(SubscriberT subscriber)
              try {
                   System.out.println("started");
                   oracleManager.persist(subscriber);
                   System.out.println("end");
              } catch (Exception e) {
                   e.printStackTrace();
    }3 and my test client :
    public class Client {
         public static void main(String[] args) {
              Context ctx = null;
              Hashtable ht = new Hashtable();
              ht.put(Context.INITIAL_CONTEXT_FACTORY,
                        "weblogic.jndi.WLInitialContextFactory");
              ht.put(Context.PROVIDER_URL, "t3://192.9.200.222:7001");
              try {
                   ctx = new InitialContext(ht);
                   InsertSubscriber usagefasade = (InsertSubscriber) ctx
                             .lookup("ejb.InsertSubscriberBean");               
              } catch (NamingException e) {
                   e.printStackTrace();
              } finally {
                   try {
                        ctx.close();
                   } catch (Exception e) {

    }what i did incorrect ???
    i got error like this : Name not fount exception
    when i tried to view jndi tree on weblogic server application console i found this :

    Hi All,
    I am using the weblogic cluster with session replication and EJB 2.0 with Local entity beans.
    for fail-over session should be replicated to another server so we can achive the same session if 1st server fails.
    Suppose i m using two managed server(server1,server2) in the cluster.I am storing the object of class ABC into session and object contains the instance of Local-EntityBean home but i put that as a transient.I have also override the readObject and write object method.
    when write object is called on 1st server,readObject method should be called on second server so we will be sure that session is replicating properly.
    pleaase find the code below : -
    public IssuerPageBean() {
    initEJB();
    private void readObject(java.io.ObjectInputStream stream) throws IOException, ClassNotFoundException {
    stream.defaultReadObject();
    initEJB();
    initializeCommonObject();
    private void writeObject(java.io.ObjectOutputStream stream) throws IOException {
    stream.defaultWriteObject();
    private void initEJB() {
    try {
    ic = new InitialContext();
    issuerHome = (LocalIssuerHome) ic.lookup("java:comp/env/Issuer");
    } catch (NamingException e) {
    e.printStackTrace();
    in my case if i am calling the constructor IssuerPageBean(),it calls the initEJB() method and lookeup the entity local home properly but when readObject method is called on another server only initEJB() method is called directly and getting the exception below :

  • Weblogic JNDI lookup in Applet

    Hi
    We are facing problem in JNDI lookup inside the applet
    here is the scenario
    We have two weblogic servers(port 7001)
    one server is main server where the Applet1 , weblogic.jar and app.htm
    are in C:\bea\wlserver6.0sp1\config\mydomain\applications\DefaultWebApp_myserver
    and another is proxy server where HTTPProxyServlet is running and one
    web.xml file ( wall these files are provided by weblogic and the port
    of proxy server is 448)
    Both the servers are running on different machines
    and when we run the client browser and put the folloing url
    http://proxyServer IP Address:448/app.htm
    we get the following exception

    It looks like the object that you have placed into the JNDO tree is not serializable or doesnt implement exernalizable!

    Hi
    We are facing problem in JNDI lookup inside the applet
    here is the scenario
    We have two weblogic servers(port 7001)
    one server is main server where the Applet1 , weblogic.jar and app.htm
    are in C:\bea\wlserver6.0sp1\config\mydomain\applications\DefaultWebApp_myserver
    and another is proxy server where HTTPProxyServlet is running and one
    web.xml file ( wall these files are provided by weblogic and the port
    of proxy server is 448)
    Both the servers are running on different machines
    and when we run the client browser and put the folloing url
    http://proxyServer IP Address:448/app.htm
    we get the following exception

  • JNDI lookup using a proxy server

    Hi,
    I'm trying to use a weblogic server as a proxy server for a cluster of
    weblogic servers. The static and dynamic content delivery works fine but
    when I try to do a JNDI lookup from an applet client, I get a name not
    resolved exception. I guess, it happens because the proxy server tries to
    resolve the name from it's JNDI tree, whereas I expect it to forward this
    request to one of the servers in the cluster. Is this possible? If it is, do
    I need to set up some parameters in the proxy server? If not, can I do this
    myself by writing a name resolution class which in turn will forward the
    request to one of the servers in the cluster?
    Any help would be greatly appreciated.
    thanks

    when u say "cluster of weblogic servers"..u mean the weblogic`s inbuilt
    cluster..
    the reason i ask is weblogic`s cluster do provide JNDI clustering too by using
    cluster-wide naming tree..

  • Stand-alone JNDI lookup of an EJB in an Enterprise Application (EAR) build

    Hi All,
    I am having some difficulty doing JNDI look up an EJB 3.0 Bean that is part of an Enterprise Application (EAR) build. Below are all the related codes:
    package ejb;
    import javax.ejb.Local;
    @Local
    public interface Hello1Local {
        public String getHello1();
    package ejb;
    import javax.ejb.Stateless;
    @Stateless
    public class Hello1Bean implements Hello1Local {
        public String getHello1() {
            return "I am Hello1 Bean!";
    package ejb;
    import javax.ejb.Remote;
    @Remote
    public interface Hello2Remote {
        public String getHello2();
    package ejb;
    import javax.ejb.Stateless;
    import javax.ejb.EJB;
    @Stateless
    @EJB(name="ejb/Hello1",
         beanInterface=Hello1Local.class,
         beanName="Hello1Bean")
    public class Hello2Bean implements Hello2Remote {
        @EJB private Hello1Local hello1bean;
        public String getHello2() {
            return hello1bean.getHello1();
    There is no problem looking up Hello2 Bean using an Application Client such as the following:
    public class LocalHelloApplicationClient {
        @EJB(name="Hello2")
        private static Hello2Remote hello2Bean;
        public static void main(String[] args) {
            System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
    }There is also no problem doing JNDI lookup (from a Stand-Alone Client the same bean if both Hello1 and Hello2 were created by themselves. ie not part of an Enterprise Application (EAR) build. However, I am wondering whether it is possible to do JNDI lookup of the same bean (Hello2) that is part of an Enterprise Application (EAR) built. Below are the type of JNDI lookup entries that I have tried without success:
    public class StandalonePojoCallHelloWorld {
        public static void main(String [] args)
            try
                InitialContext jndiContext = new InitialContext();
                Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("ejb.Hello2Remote");
                                                                     or
                Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2.remote");
                                                                     or
                Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.ejb.Hello2Remote");
                                                                     or
                Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2Remote");
                                                                     or
                Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote");
                System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
            catch (javax.naming.NamingException ne)
             ne.printStackTrace();
    They all came up with the same error message:
    javax.naming.NameNotFoundException: LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote not found

    Hello
    I've somme problems to get access to ejb interface from remote stand-alone client.
    Here is my EJB code :
    package stateless;
    import javax.ejb.Stateless;
    @Stateless(name = "TestSB", mappedName = "ejb/stateless/TestSB")
    public class TestEJBBean implements TestEJBRemote {
        public String getMessage() {
           return "Hello EJB World";
    }And the remote interface :
    package stateless;
    import javax.ejb.Remote;
    @Remote
    public interface TestEJBRemote {
        String getMessage();
    } In client side, i just edit main.java like this :
    package testclient;
    import java.io.FileInputStream;
    import java.util.Properties;
    import javax.naming.InitialContext;
    import stateless.TestEJBRemote;
    public class Main {
        public static void main(String[] args) throws Exception {
            Properties props = new Properties();
            props.load(new FileInputStream("jndi.properties"));
            InitialContext ctx = new InitialContext(props);
            TestEJBRemote testEJB = (TestEJBRemote) ctx.lookup("ejb/stateless/TestSB");
            System.out.println(testEJB.getMessage());
    }here is my jndi.properties file (my glassfish server IP is 192.168.0.10) :
    java.naming.factory.initial = com.sun.enterprise.naming.SerialInitContextFactory
    java.naming.factory.url.pkgs = com.sun.enterprise.naming
    java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
    org.omg.CORBA.ORBInitialHost = 192.168.0.10
    org.omg.CORBA.ORBInitialPort = 3918when i run client on the same machine than the glassfish app server, it works fine.
    But i run it on the different machine than the glassfish app server (on the same LAN without firewall), it fails with this error message :

  • Doing a jndi lookup() for an EJB deployed on Glassfish v3

    Hello.
    I have deployed a Stateful Sesion EJB on a Glassfish v3 AppServer.
    It is running under 'localhost' on my laptop pc.
    I am also running a stand-alone java application on the same pc... it attempts to get a remote connection from the client-app to the Glassfish Server and then do a jndi lookup() to get a reference to my EJB.
    here is the client source code:
    public class LookupTest {
    static Properties props = null;
    public static void main(String[] args) {
    try {
    props = new Properties();
    props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
         props.put(Context.PROVIDER_URL, "iiop://localhost:3700");
         Context ctx = new InitialContext(props);
         System.out.println( "the context is: " + ctx);
         System.out.println( "the environment contains: " + ctx.getEnvironment() );
         System.out.println( " ");
         // do a lookup.
         Object elementObj = ctx.lookup("SerialContextProvider");
         System.out.println(elementObj);
    } catch (NamingException e) {
    e.printStackTrace();
    When I run this app, there are no Errors or Exceptions. It appears that the connection succeeds. But there are no EJB references in the context that is created. The only item that seems to be present in the context is an item named "SerialContextProvider", as noted in the return value from a list("") method invocation. Why can i not see the EJB within the context? Is my code wrong ??
    Thanks,
    Andy Jerpe

    Ok, but the communication seems to be OK over the wire because if I use netstat -a I can see the ESTABLISHED connection with the server in the right RMI port.
    TCP PORTAL35:1581 caapiranga:12405 ESTABLISHED
    and then when I stop the instance in the OAS, the client shows an exception telling that the connection was lost.
    An curious thing is that the ons.log doesn't log this connection ;/

  • JNDI Lookup Problem (General Problem)

    hi all,
    i am newbie on bea products, but i have some experience on java technologies, how i fount on bea documentations and forums many people has the same problem like this, can anybody help us (me)?
    problem: how is it possible to write simple client for j2ee server application? i found some posts about jndi lookup, and fount about j2ee client, but is there any doc or example how to write this j2ee client ???
    i worked with many application servers and i have no problem with them (JBoss, Sun App Server, IBM Websophere, Oracle AS etc.)
    some people told about jndi tree on Web Logic Server Administration console , i found this tree i my session beans looks like :
    Binding Name:
    TimestenExampleTimestenExample_jarInsertSubscriberBean_InsertSubscriber
    Class:     
    test.InsertSubscriberBean_o7jk9u_InsertSubscriberImpl_1000_WLStub
    why is so strange name for class or binding name ????
    my session bean name is : InsertSubscriber
    and it's implementation : InsertSubscriberBean
    how i can lookup from client ?????
    can anybody show me code snippet ???
    my client looks like :
    import java.util.Hashtable;
    import javax.naming.Context;
    import javax.naming.InitialContext;
    import javax.naming.NameClassPair;
    import javax.naming.NamingEnumeration;
    import javax.naming.NamingException;
    import org.hibernate.property.Dom4jAccessor.ElementGetter;

              Context ctx = null;
              Hashtable ht = new Hashtable();
              ht.put(Context.INITIAL_CONTEXT_FACTORY,
                        "weblogic.jndi.WLInitialContextFactory");
              ht.put(Context.PROVIDER_URL, "t3://192.9.200.222:7001");
              try {
                   ctx = new InitialContext(ht);
                   InsertSubscriber usagefasade = (InsertSubscriber) ctx
                             .lookup("java:comp/InsertSubscriber");
              } catch (NamingException e) {
                   e.printStackTrace();
              } finally {
                   try {
                        ctx.close();
                   } catch (Exception e) {
                        e.printStackTrace();
    }can anybody show me what is there incorrect ????
    oo yes and i have weblogic.jar file into my client classpath.

    Hi,
    Your EJB client looks fine.
    You should use the JNDI name of your ejb while doing the lookup. i.e :
    InsertSubscriber usagefasade = (InsertSubscriber) ctx.lookup("..use JNDI name of EJB...");
    You can use the JNDI name of the EJB that you see in the JNDI tree of weblogic. [don't use Binding Name or Class name]. you can also specify the JNDI name by "jndi-name" attribute in weblogic-ejb-jar.xml.
    for more info:

  • JNDI lookup for UserTransaction

              Hi all,
              in Weblogic, in a typical scenario, do a client provide exactly
              one JNDI lookup for the UserTransaction object (interface) or do
              the client have to provide a JNDI lookup for each transaction?
              In some EJB implementations, a JNDI lookup for UserTransaction
              returns always the same reference. For example, in JOnAS, you can
              have one static reference which is set when the client starts.
              Then, more threads can simultaneously use the same static
              UserTransaction reference without any conflict, since the
              implementation of UserTransaction recognizes, which thread invoked
              a particular method.
              In other words, can I make an assumption that two different JNDI
              lookups for UserTransaction returns different references or not?
              Thanks a lot,

    Actually, UserTransaction is a singleton and it's not a transaction. It's just
              very mis-named.
              It should be called UserTransactionManager or UserInterfaceToJTA.
              The actual transaction is javax.transaction.Transaction.

  • JWS - EJB JNDI Lookup problem

    Hi,
    I have a client Java application accessing a session EJB in a remote JBoss J2EE server. I'm using JWS 1.2 to deploy my application but when I do a JNDI lookup to get access the the remote's object home interface I get this error:
    "Need to specify class name in environment or system property, or as an applet parameter, or in an application resorce file: java.naming.factory.initial"
    All the jar files are signed and the JNPL file contains <all-permissions/>. This is the code that triggers the exception
    jndiContext = new InitialContext();
    homeRMIReference = jndiContext.lookup(C_SERVICE_NAME);
    Any help would be appreciated.
    Thanks in advance,
    Rafael

    Hi,
    I've finally found the origin of the problem.
    1. JNDI uses a minimum set of properties during initialization phase:
    java.naming.factory.initial
    java.naming.factory.url.pkgs
    java.naming.provider.url
    Therefore these properties must be set in the <resource> topic of the JNLP file. The value of these properties is defined in the jndi.properties file that you can find in jbossjmx.ant.jar (within the jboss/client directory)
    2. You have to add the JBoss files to your bundle. For doing so I've unjared all the .jar files within the jboss/client directory; afterwards I have jared them in a single file "jboss.jar" and I've signed the file. I've added jboss.jar to the <resource> tag within the JNLP file (Note that I've added all the jboss files just to do quick check but usually you will have to add only those files you need (it doesn't make sense to deploy all JBoss files in each client application)
    I hope this helps,
    Rafael

  • JNDI lookup through COMP_NAME

    Hello Frnds,
    I am using xdoclet 1.2 feature in my application to generate the stubs for ejb bean classes.
    and i am using the websphere application server to deploy my application.
    Please find the code below :
    In Home class
    public static final String COMP_NAME="java:comp/env/ejb/TestEJBLocal";
    public static final String JNDI_NAME="ejb/TestEJBLocal";
    In Bean Class
    @ejb.bean name="TestEJB" view-type="local"
    * local-jndi-name="ejb/TestEJBLocal"
    * type="CMP" reentrant="False" cmp-version="2.x" schema="Test"
    * primkey-field="testID"
    For lookup:
    public EJBHome lookUpHome(Class homeClass) throws HomeFactoryException {
              try {
                   EJBHome ejbHome = (EJBHome) _ejbHomes.get(homeClass);
                   if (ejbHome == null) {
                        ejbHome = (EJBHome) PortableRemoteObject.narrow(_context
                                  .lookup("*java:comp/env/ejb/TestEJBLocal*"), homeClass);
                        _ejbHomes.put(homeClass, ejbHome);
                   return ejbHome;
              } catch (ClassCastException e) {
                   throw new HomeFactoryException(e);
              } catch (NamingException e) {
                   throw new HomeFactoryException(e);
    When i pass the COMP_NAME for lookup, application is throwing an exception like Name Not Found exception.
    The problem i'm facing here is, JNDI lookup is not happening through COMP_NAME.
    Could someone help me on resloving this problem.
    Helping on othis highly appreciated :)
    Cheers,
    Cap

    Hi:I'm unable to get JNDI reference object from remote application client with "java:comp/env/ejb/<lookupName>".
    The exception says:
    Application threw an exception:javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE:   vmcid: SUN  minor code: 201 completed: No]
    The J2EE server and client are run on different machines, and needs to be like this. There isn't any problem with JSP/Servlet (cause they run/execute on the server itself). How will the client find out the JNDI refernce my mere specification of "java:comp/env/..."?
    Am I making a mistake anywhere?
    BEA Weblogic & IBM Websphere allows explicitly specifying the server name, while doing JNDI lookup. Is there anything similary for J2EE?
    I couldn't find reference for this anywhere in the J2EE tutorial or EJB books.

  • How to Lockup unauthorized JNDI Lookups

    Hello,
    I am running JNDI datasource from my Weblogic Server. I wrote an unauthorized
    client that makes a lookup on the JNDI "someJNDIName" and the program basically
    gets data from a table. See below....
    How do I lockup unauthorized clients? I want only the JSP pages to do the JNDI
    lookup and do the processing.
    Is there any setting I have to do, so that only authorized clients can access
    the JNDI?.
    Thanks.

    Hi,
    Take a look at the following:
    http://e-docs.bea.com/wls/docs70/secwlres/secroles.html#1208744
    That is for WLS 8.1. Other versions' docs will have a similar link. Also make
    sure that you disable user guest. This is done as the default in WLS 7.0 and
    higher. Prior to 7.0 you disable guest user through the console.
    Hope this helps,

         ... 38 moreCan any body tell me what's wrong with it? i have seen all the stubs generated it is looking for but not able to load/recognize it? And also i need to mention other problem is that everytime i compile, deploy and start the server i am getting open failure exception and server not recognizing the ejb jar and if i close and restart the RSA server starts well.
    Pls help me in solving this issue.

    Hi All
    Two separate webapps, have different names for
    Datasources, on the same host and port. Both
    application work fine independently.
    When we deploy both applications on the same app
    server(websphere), whichever we executes first gets
    its datasource from JNDI lookup and works fine, but
    when we try second application it have problem in
    finding its data source from JNDI lookup. If we start
    this second application first, it will work fine, but
    now another will have the same problem in its JNDI
    lookup.
    Any idea why.
    Thanks
    ....RanvirHi Ranvir,
    Do you mean you try to reach the same datasource with different names or do you try to reach different datasources over the same port?
    If you try the first issue you shouldn't get any trouble. At least it works fine with JBOSS for example.
    But if you try to do the latter in my oppinion you don't have a JNDI problem but a problem with socket binding: the two different databases must be contacted over different ports.
    What do WebSphere's logs tell?
    Best regards
    Andy

  • Could not access Local Session Bean using JNDI lookup

    Hi EJB Guru,
    I am quite new to EJB 3.0 but have had a good deal of success including using JNDI to lookup Remote Stateless Session Bean in EJB 3.0. However, looking up local Stateless Session Bean prove more challenging with I had anticipated.
    Here is my code
    as follows:
    public interface Calculator {
        public int add(int x, int y);
        public int subtract(int x, int y);
    import javax.ejb.Remote;
    @Remote
    public interface CalculatorRemote extends Calculator {
    import javax.ejb.Local;
    @Local
    public interface CalculatorLocal extends Calculator {
    import javax.ejb.Local;
    import javax.ejb.Remote;
    import javax.ejb.Stateless;
    import bean.CalculatorLocal;
    import bean.CalculatorRemote;
    @Stateless
    public class CalculatorBean implements CalculatorRemote, CalculatorLocal {
        public int add(int x, int y) {
            return x + y;
        public int subtract(int x, int y) {
            return x - y;
    import bean.*;
    import bean.Calculator;
    import bean.CalculatorLocal;
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    public class ClientAccessLocalCalculator {
        public static void main(String[] args) throws NamingException {
            InitialContext ctx = new InitialContext();
            CalculatorLocal calculator = (CalculatorLocal) ctx.lookup("CalculatorBean/local");
            System.out.println("1 + 1 = " + calculator.add(1, 1));
            System.out.println("1 - 1 = " + calculator.subtract(1, 1));    }
    import bean.Calculator;
    import bean.CalculatorRemote;
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    public class ClientAccessRemoteCalculator {
        public static void main(String[] args) throws NamingException {
            InitialContext ctx = new InitialContext();
            CalculatorRemote calculator = (CalculatorRemote) ctx.lookup("CalculatorBean/remote");
            System.out.println("1 + 1 = " + calculator.add(1, 1));
            System.out.println("1 - 1 = " + calculator.subtract(1, 1));    }
    }Output when running ClientAccessRemoteCalculator gives

    Hi Henry,
    Any direct global JNDI lookup is not portable. It works in some cases but not in others, which
    is why we recommend using the portable Java EE approach of declaring an ejb dependency
    and looking up that dependency via the bean's component environment (java:comp/env).
    This is true whether you're dealing with Remote or Local ejb dependencies.
    Local ejbs are not supported in the Application Client tier at all. In the server tier, there is no
    guarantee that a Local EJB even is assigned a global JNDI name since there's no requirement
    that it be available outside of the application in which the ejb is defined.
    You can find more information on these ejb access topics in our EJB FAQ :
    https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html

  • Cost of a local JNDI lookup

    5.1sp8
    I always thought that cost of a local JNDI lookup is pretty
    small, but just found that it is not:
    application JSP's extend common superclass which does(did!) JNDI
    lookup based on the URI and sets a threadlocal variable before
    invoking jspservice() method.
    During performance testing replacing JNDI with a static hashtable
    improved thoughput by ~25-30% (pages themselves are very fast -
    mostly jsp cache tags hits).
    Weird.

    First of all I am not caching the Initial Context. I am caching the results
    of the initial context lookup into a hashmap (I have changed this from
    hashtable, which I proposed originally in my posting - see my latest post).
    Second, if you have client running in seperate JVM, can not lookup the
    hashmap created by the server.
    Third, on the server side, you cannot get a reference of a startup class.
    The server simply instantiates the class and invoke startup() method (from
    T3StartupDef interface) and it does not keep reference after startup()
    method returns. But you could use another class that you want to get an
    instance of by creating it within the startup class and provide a static
    method to create/return that instance. I guess the proper way of saying it
    would be create the hashmap as a class variable in a singleton class
    (hopefully you get the idea)...

    Raja,
    We are also wrapping all the JNDI requirements in a startup class and WL
    loads it automatically. Now my problem is how to access the InitalContext
    (initialized by startup class) by a client and also on the server side. If
    you have any code that explains that, please pass it along.
    Thanks

    Mike,
    Thanks for the reply to the previous message. For the particularbenchmark,
    I knew all the JNDI lookup requirements at the design time (I think that
    would be the case in most applications), so I wrapped them into a startup
    class.

    In the code where you need the context ...
    static Hashtable h=new Hashtable();
    ctx=h.get(ctx_name);
    if(ctx == null){
    ctx=new InitialContext(... args ...);
    h.put(ctx_name, ctx);

    Can you explan what you mean by "use a static hash table"? We did some

    testing on 6.0 SP 1 and saw that
    creating an local initial context is fairly costly and I would like to
    understand your solution. Thanks.

    Dimitri,
    I was surprised to see that in WLS 5.1. I have seen this on 6.0 and
    understood that JNDI lookups need to be sereilized because of the newclass
    loader. In the recent benchmark, for 6.0 we found that the about
    15-20%
    of
    the (client's) application CPU time was spent on JNDI lookup
    (serealization). We changed it to a static hash table.
    Unfortunately, I am only seeing marginal gain in 5.1sp8.
    For all 6.0 applications we are going to use static hashtable. Mightas well
    do it now for 5.1 so that your migration to 6.0 will be easier :).

    This is irritating. If I remember correctly, until now the official
    statement was that it's not even worth caching an InitialContext ifit's
    a local one. Guess I'll have to review my application for this as
    well.
