Calling a static method when starting the server???

Hi,
i wanted to call a static method of a java class,
whenever i start the server.
plz give some input on this.
thanks and regards
siva

Siva -- Can you be more specific as to the problem you are trying to solve (why do you want to call this static method,.)
The reason I ask is that there are some ways to make this happen but they may have limitations
that won't work for you. For instance, you can create a servlet that calls your class' static method and then make the
servlet be loaded on startup.
Thanks -- Jeff

Looks like you cannot connect to LDAP. Are you configured correctly?

Can we call a static method without mentioning the class name

public class Stuff {
     public static final int MY_CONSTANT = 5;
     public static int doStuff(int x){ return (x++)*x;}
import xcom.Stuff.*;
import java.lang.System.out;
class User {
   public static void main(String[] args){
   new User().go();
   void go(){out.println(doStuff(MY_CONSTANT));}
}Will the above code compile?
can be call a static method without mentioning the class name?

Yes, why do it simply?

WLST problems when starting the server

Hi all,
I try to use WSLT (with ant) to start bea within an existing domain. The ant target is:
<target name="start-server">
<echo message="Starting bea weblogic..."/>
     <wlserver
     dir="${domain.home}"
     beahome="${weblogic.home}/.."
     weblogichome="${weblogic.home}"
     servername="${server.name}"
     domainname="${domain.name}"
     username="${weblogic.user.name}"
     password="${weblogic.user.password}"
     host="${server.host}"
     port="${server.port}"
     generateconfig="false"
     action="start"
     failonerror="true"
     configFile="/config/config.xml"
     classpath="${weblogic.home}/server/lib/weblogic.j ar"
     verbose="true"
     />
</target>
Unfortunately I got hundrets of NoClassDefFoundError when running this target. Serveral for each deployed component. Therefore I put classpath extensions to different files:
1. %BEA_HOME%\user_projects\domains\wcsdomain\bin\startWebLogic.cmd
2. %BEA_HOME%\user_projects\domains\wcsdomain\bin\setDomainEnv.cmd
3. %BEA_HOME%\weblogic91\common\bin\commEnv.cmd
4. %BEA_HOME%\weblogic91\server\binsetWLSEnv.cmd
But the classes are still missing.
Question:
Can anyone tell me where to put classpath extensions for the deployment jars?
Thanks

You are not using WLST any where, you are using the wlserver ant task. The wlserver ant task does not use the scripts to start the server. You should add the jars to the wlserver classpath element.

Messages when starting the server

Hi,
I am using OC4J 10.1.3.
When i start the server i am getting this message
May 5, 2005 10:09:14 AM com.evermind.server.ejb.EJBPackageDeployment isIIOPConfigured
INFO: Beans associated with application Twe will not be available via RMI/IIOP: GenerateIIOP system property=false, enableIIO
P application setting=false, server.xml configured for IIOP=true
May 5, 2005 10:09:14 AM com.evermind.server.ejb.EJBPackageDeployment isIIOPConfigured
Any idea why this is coming. Does this mean that my beans are not deployed or I will not be able to access them.
Thanks
Kiran
----

Kiran, there is no real problem here; the message, of type "INFO", is just to inform/warn you that your application is not properly configured for the purpose of accessing it through RMI/IIOP. Your beans are deployed and you will be able to access them as long as you are not using RMI/IIOP; otherwise, there should be other real error message printed out.
Furthermore, this message is in the process of moving to some log file instead of popping up when the server is started. So, you probably won't notice them the next time you install a newer oc4j.
Hope this helps.

Getting serailization exeception when starting the server

Hi All,
I succesfully got the "ComputeEngine" running from the basic RMI tutorial.
I then began reating my own classes based on the tutorial, which is still basically copied code from ComputeEngine.java.
For some reason when when I try to start my server class I get a "Not serializable" exception. This can be fixed by adding "implements Serializable" to my class. But what I'm confused about is that the ComputeEngine class from the tutorial does not require the "implements Serializable". Why does mine require it?
Anyone have any ideas?
Here is my code:
public class RemoteExecuteServer implements RemoteExecute, Serializable {
    public RemoteExecuteServer() throws RemoteException {
        super();
    public Object executeRunnable() throws RemoteException {
        System.out.println("Hello, this is the server.");
        return null;
    public static void main(String[] args) {
        if (System.getSecurityManager() == null) {
            System.setSecurityManager(new RMISecurityManager());
        // TODO: Get the server name from a config file
        String name = "//sunxxx/RemoteExecuteServer";
        try {
            RemoteExecute engine = new RemoteExecuteServer();
            Naming.rebind(name, engine);
            System.out.println("RemoteExecuteServer bound");
        } catch (Exception e) {
            System.err.println("RemoteExecuteServer exception: " +
                      e.getMessage());
            e.printStackTrace();
}

Never mind,
I wasn't extending UnicastRemoteObject. Thanks anyway.

Redirecting output when starting the server as Service

Hi,
I was wondering if there is any way to redirect the error to a log file if the
weblogic server has been started as Service. We are getting some crashes and we
are not sure what exactly the issue is. We have tried running it on the command
line and we have been able to capture some info but if there is a way to do the
same when starting it as service,it would be great
thanks
Sushil

wls8.1 sp3:
To redirect the output to log files you must redirsct standard out and standard error to a file.
This can be done by following steps:
1.     Create a backup copy of the WL_HOME\server\bin\installSvc.cmd master script.
2.     In a text editor, open the WL_HOME\server\bin\installSvc.cmd master script.
3.     In installSvc.cmd, the last command in the script invokes the beasvc utility. At the end of the beasvc command, append the following command option:
-log:"pathname "
where pathname is a fully qualified path and filename of the file that you want to store the server's standard out and standard error messages.
The modified beasvc command will resemble the following command:
"%WL_HOME%\server\bin\beasvc" -install
-svcname:"%DOMAIN_NAME%_%SERVER_NAME%"
-javahome:"%JAVA_HOME%" -execdir:"%USERDOMAIN_HOME%"
-extrapath:"%WL_HOME%\server\bin" -password:"%WLS_PW%"
-cmdline:%CMDLINE%
-log:"d:\bea\user_projects\domains\myWLSdomain\myWLSserver-stdout.txt"
4.     By default, every 24 hours the Windows service archives messages to a file named pathname-yyyy_mm_dd-hh_mm_ss. New messages collect in the file that you specified in the previous step.
For information on changing the default behavior, see Changing the Default Rotation Criteria <http://e-docs.bea.com/wls/docs81/adminguide/winservice.html>.
After you install the service and restart the Windows host, to view the messages that the server writes to standard out or standard error, do one of the following:
§     Make a copy of the file that you specified and view the copy. The Windows file system cannot write to files that are currently opened.
§     To view the messages as they are being printed to the file, open a command prompt and, using a DOS utility that supports the tail command, enter tail -f stdout-filename.

How to call a static method in a class if I have just the object?

Hello. I have an abstract class A where I have a static method blah(). I have 2 classes that extend class A called B and C. In both classes I override method blah(). I have an array with objects of type B and C.
For every instance object of the array, I'm trying to call the static method in the corresponding class. For objects of type B I want to call blah() method in B class and for objects of type C I want to call blah() method in C class. I know it's possible to call a static method with the name of the object, too, but for some reason (?) it calls blah() method in class A if I try this.
So my question is: how do I code this? I guess I need to cast to the class name and then call the method with the class name, but I couldn't do it. I tried to use getClass() method to get the class name and it works, but I didn't know what to do from here...
So any help would be appreciated. Thank you.

As somebody already said, to get the behavior you
want, make the methods non-static.You all asked me why I need that method to be
static... I'm not surprised to hear this question
because I asked all my friends before posting here,
and all of them asked me this... It's because some
complicated reasons, I doubt it.
the application I'm writing is
quite big...Irrelevant.
Umm... So what you're saying is there is no way to do
this with that method being static? The behavior you describe cannot be obtained with only static methods in Java. You'd have to explicitly determine the class and then explicitly call the correct class' method.

Memleak cannot work when start the management server by ctrlhandler.act

Hi, all
I use ctrlhandler.act to start a management server on running system. when start the memleak detector, i got the error message on server output:
[JRockit] ManagementServer started trend analysis
java.lang.NullPointerException
Continuing ...
java.lang.Exception: discarding statement XMLEncoder0.writeObject(HeapHistogram0);
Continuing ...
but when I started the management server with command line -Xmanagement. all is ok. What's the matter?
Thanks a lot!

Sorry, the jrocki version is 1.4.2_05 and 1.4.2_08.
And the os: windows XP professional and Redhat AD 7.2
And the weblogic server version is 'weblogic8.1 sp3'
any suggestion? Thank you!

Oracle Error when starting the WLI server (samples domain) on Windows XP

I've installed WLI (SP2) on Windows XP and after Starting the Server (from the
"Start Server and Launch Examples" commands on the start menu) I get the following
Oracle error in the console:
I'm using WLI 7.0 with SP2 and Oracle 9i on Windows XP Home.
ORA-12154: TNS:could not resolve service name
Any ideas?

Hi Peter,
Based on the error messages it looks like this might be a Windows 7 security issue, which would be why it doesn't occur on XP since security is handled differently in that OS. Have you gone into dcomcnfg.exe and checked the DCOM permissions as described in the error message?

Dynamically load the content without re-starting the server

Let me explain the scenario.........
I have a JSP in which I call a method written in a different class( java file).
Now, when I change the content of the method in the class and compile it, how can I get the updated stuff in the JSP without re-starting the server.
Even though I have to re-deploy the changed class, I need to re-start the server to get the updates effective.
The env set up is on Tomcat
fun_one

FUN_ONE, I am using Tomcat 5.0 (though not 5.5), and have a Test application that I do not use WARs to deply. The Context is set with reloadable="true".
I have this simple bean:
package jsp.beans;
public class ItemBean implements java.io.Serializable
     public String getjunk() { return "Hello"; }
} And this JSP
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
</head>
<body>
    
    <p><c:out value="${pageContext.session.id}"/></p>
    
    <p><jsp:useBean id="it" class="jsp.beans.ItemBean"/>
    <c:out value="${it.junk}"/></p>
</body>
</html> I run the JSP, then change the text returned by the bean, recompile it, then reload the JSP (force reload). The session id remains the same, and the text changes. Does this work on your system? (note, you do have to restart your server once after you set the Context to be reloadable="true")

Marco.
Sorry, this is not a solution to your problem but i am trying to solve the same
problem for a week now.
I have wl7.0 sp2, 1 admin server, 2 managed servers on the same box. I get the
same error. I know that the default certificate installed provides a hostname
verification of weblogic.com. I turned the hostname verification off, i put in
the Dweblogic.nodemanager.sslHostNameVerificationEnabled=false, i get the same
error when starting the managed server. I went ahead and created my own certificate
for machine called mallik, created my own passphrase, created a new keystore,
made the admin server view the keystore, used the same certificate for both the
admin server and the node manager. It still fails with the same error. I went
ahead and added the machine 'mallik' to nodeManager.hosts file. It fails. I am
totally confused now what needs to be done.
My nodeManger.hosts looks like this:
mallik 10.100.10.130
managedServer1 10.100.10.130
managedServer2 10.100.10.13
