Info on startup classes

Hi. I am trying to create one startup class. It is in mine classpath and I declared
it in console. I registated it with my server but in the start up the system returns
one java.lang.ClassNotFoundException. Is necessary to initiate some classpath specific
for the classes of startup?
Thanks in Advance

Startup classes is not described in J2EE specs, hence is handled independently by vendors and is
very awkward.
You can, however, create a startup servlet, that mimics a startup class and is J2EE-portable.
Search interest.ejb; info has been posted there about this.

Yes, it needs to be in the CLASSPATH of startWeblogic.sh.Is there perhaps the posibility to define startup classes in enterprise
applications? Or do you have to edit the config.xml by hand or by the
console for that?

Startup class question

Hi,
I haven't used startup classes but see a need for one now, to add a JMS
receiver of messages. We're not on WL 6.0 yet and that doesn't appear to be
an option. Anyway, my question relates to threading. Are startup classes
like EJB's
in that the server will instantiate > 1 if needed?
Thanks,
Bill

Bill,
Your threading needs depend on how you are using JMS. If you are using
asynchronous delivery then the thread is provided by the JMS runtime when it
makes the callback on to your listener.
If you hope to use synchronous delivery then you'll need a thread to receive
messages. A startup class could probably start a thread (or a pool of them)
and use them to handle synchronous messages. However I would strongly
recommend against this.
You might investigate Message Driven EJBs. I suspect that they will be a
better fit for your needs than a startup class.

Hi,
So if there is only one instance what happens if multiple requests come in
at the same time?
BTW, the startup class I am working on will be for a JMS client.
I suppose you could thread the startup class?
Where can I find detailed info on Startup classes beyonnd what have found
in the developers manual?
Thanks alot,
Bill

Failed to invoke startup class "MyStartup Class"

Hi,
I configured StartUpClass.java in Weblogic server through Admin Console . Also I set the required jar files in the classpath of the server in WL_HOME\server\bin\startWLS.cmd.
This StartUPClass is written to initialize and create the minimum number of objects in the pool, needed for URLConnection using ObjectPooling API.
I am getting Exceptions while starting the server after deployment of the application. I am pasting the full stack trace.

I should be more specific and have a bit more to add....
We have our app in an .ear file. I find that when I put the startup
classes in a seperate directory which is in the classpath specified in the
startWeblogic.cmd file they will be run on startup. I don't think I should
have to do this since these files exist in the ear file. I think this is
causing other problems too such as an illegalAccessError I get when an EJB
tries to load a class which was previously accessed by the startup classes.
Thanks,
Steve

Startup Class in WebLogic server 6.1

I Have a Java application as startup class in Weblogic server 6.1 . I need to stop
the application without restarting the Weblogi server (The startup class should
be removed and the change should be reflected in WebLogic server). Is it possible
to achieve this. I Know that we can remove the startup class from the console
but the change is getting reflected only if i restart the WebLogic Server. Can

Even if it is EJB-only, adding .war with startup logic will be more convinient
than startup classes.

Removing Startup classes on Iplanet 6.5

Hi,
I have deployed a startup class on the application server using the following command:
iasdeploy deploystartup
Can anyone please tell me how to safely remove the startup class please?
Thanks in advance

Hi Christian,
I think the restriction for development and deployment of custom services will remain in the future. About "startup classes" - I'm not sure if there are such plans but I'll try to find some info and tell you once I have it - hopefully chances are better here.
Meanwhile, could you delve a little bit more into the details of your scenario - what type of initialization and caching would you like to do? Maybe we could find some workaround in your situation.
Best regards,
Vladimir

In web.xml configuration I gave <load-on-startup></load-on-startup> .I created a war and an ear and deployed my application .The startup class is not called.
But when I configured the servlet in the default-web-app the startup class is running.
And furthur when I hot deploy my ear the startup class is running.
But when I restart my application server the startup class is not invoked.

Problems in startup class (MDB on Weblogic 7.0 / IBM MQ)

Hello friends,
          I am trying to communicate with IBM MQ through Weblogic 7.0 SP2 and
          using MDB.
          This is a bit strange but I had to reinstall Weblogic and I tried to
          deploy the Startup class . However I am getting this error:
          The WebLogic Server did not start up properly.
          Exception raised:
          java.lang.NoSuchMethodError
          at com.ibm.mq.jms.services.ConfigEnvironment.<clinit>(ConfigEnvironment.java:173)
          at java.lang.Class.forName0(Native Method)
          I am totally at loss to understand this as it was working before I
          reinstalled the Weblogic. (Maybe I am skipping something which I had
          earlier done :-().
          All help appreciated.
          Thanks in advance,
          Milan Doshi


Since your simply running an MQ client in a startup class, you should
          be able to reproduce the issue without WebLogic in the mix. Once
          that is done, contact IBM for support. I continue to suspect
          a command-line problem - IBM is expecting something on
          the java JVM command-line that is missing.

Class not found exception for the startup class defined.

iam using weblogic server 10 and bea jrockit 1.5.0.12.
i have created a startup class in the admin console for a web project and i have deployed the war file using the console in a user defined domains, user project directory.
when i start the server, iam getting class not found exception for the startup class.
But, the startup class is available in the web archive (war). how should we add the classes and jars in the war to the classpath in setDomainEnv.sh or is there any other setting available in the console to enable this.

Hello Julius,
yes sure, we can move this post to the NW admin forum. I have already posted similar thread on sun forums. I was hoping that someone from SAP SDN already tackled this problem and if not someone specialized in J2EE Engine could troubleshoot me from the class problem I'm getting. I don't know if it's specific from the agent or if this ClassNotFound is a general SAP J2EE Engine error relating to a library not correclty defined.
Kind regards,
Tanguy Mezzano

Redundancy for startup class.

Hi,
I have a startup class in weblogic server. This class acts as a daemon inside
weblogic server. What happens if this class goes down due to an exception after
a while ? does the weblogic server brings it up again or can we configure it or
is it just lost?
-Kishan-

It it runs in its own thread why don't you just do something like this:
public void run()
............ //initialization
while(!shouldStop)
try
catch(Throwable th)
th.printStackTrace();
and you wouldn't need anything like the functionality you are describing which I do
not believe BEA does.

A startup class to enable MQ Queues to trigger MDBs in WLS 6.1(sp4)

          Hi,
          I am hoping for references to documentation or opinions on the following method
          allowing the use of MQ queues to drive MDBs in WLS. The technique involves rebinding
          the connection factory in jndi at "weblogic.jms.MessageDrivenBeanConnectionFactory"
          with MQs connection factory.
          I read in various newsgroup posts that replacing WLS' ConnectionFactory with MQ's
          in a startup class will not allow MDBs to be linked to an MQ queue because startup
          classes are run after MDB deployment during startup. However I found some unused
          in-house code which appeared to do just that and it works.
          Here is the code in abbreviated form:
          public String startup(String str, Hashtable args) throws Exception
               bindMQFactory();
               bindMQQueues();
               return "";
          private void bindMQFactory() throws Exception
               // Create MQ Factory and configure it
               MQQueueConnectionFactory factory = new MQQueueConnectionFactory();
               factory.setChannel(channel );
               factory.setHostName(host);
               factory.setPort(Integer.parseInt(port));
               factory.setQueueManager(qmanager);
               factory.setTransportType( JMSC.MQJMS_TP_CLIENT_MQ_TCPIP );
               // bind connection factory into WLS JNDI for later use by clients
               _wlsContext.bind( connectionFactoryJndi, factory );
               // Force mq connection factory to be the one used for mdb's
               _wlsContext.rebind("weblogic.jms.MessageDrivenBeanConnectionFactory", factory);
          private void bindMQQueue() throws Exception
               // create queue and configure it
               MQQueue queue = new MQQueue();
               queue.setTargetClient(JMSC.MQJMS_CLIENT_NONJMS_MQ );
               queue.setBaseQueueName( mqQueueName );
               // bind queue in WLS JNDI
               _wlsContext.bind( wlsJndi, queue );
          Thanks in advance for any comments or opinions on the above.
          regards
          Martin


Start with the white-paper:
          "Using Foreign JMS Providers with WebLogic Server"
          Note that to get transactional behavior you
          will need to use the WebLogic Messaging Bridge feature.
          Note that integrating MQ is easier in 8.1 - consider
          using WL 8.1 if you can.
          One more comment in-line.

          Not recommended. Highly not recommended. Do not use the same name
          as the internal factory. Create your own name for a CF, and change the
          weblogic ejb jar to reference your name. The above white-paper
          states how to do this.

How to define my startup class in an .ear package?

I am using WL6.0SP2 on solaris.
I plan to package my application as an .ear file and to put all necesarry class
files in there (it will has one .war file for the web tier and one .jar file for
the EJBs).
I want, when Weblogic loads my .ear file (i.e. my application), to execute my
special startup class, which initializes some caches, etc.
I do not want to define a startup/shutdown class in the console, because it is
only specific to my application and this startup class is not present in the weblogic
classpath during weblogic startup.
The correct place should be in application.xml, but I don't see such thing in
the DTD.
Thank you,
Ivaylo Zlatev

There is no way to do this on the EAR level - you can use load-on-startup
servlet(s) in your web component, or initial-beans-in-free-pool=1 EJB.

Security settings for startup class

Hi,
I use WL6.1 (sp2) where the "guest" user is disabled and server starts up with
"system" user. All beans are permitted to be launched using other user "user1"
and not "system" user. And the jar file with beans and other staff is deployed
well, except of one thing:
I have startup class in the application and it doesn't work. When trigger method
is launched, the following exception is thrown:
<WispConfiguration: Can't connect to bean. No configuration avaiable java.rmi.AccessException:
Security violation: insufficient permission to access method; nested exception
is: java.lang.SecurityException: Security violation: insufficient permission
to access method>
As i understand this is the security problem. How could I configure weblogic
to make him to use "user1" instead of "system" when running startup class? Where
should I define it: in startup() method of startup class or in configuration files
of WL?
Any help/hint will be very appreciated.
THANKS
Orly

i took all the folders out and restarted and the same message came up that the startupitems folder is insecure and a second message saying that folder DS_Store in the startupitems folder is disabled because of insecure settings. Now I can not see that folder in the startup items folder, any idea
Probably just as it says, DS_Store is corrupt. This stores the settings for a folder.
To see if we can find the invisible folder and remove it open Terminal in your Utilities folder and at the prompt copy and paste defaults write com.apple.finder AppleShowAllFiles True; killall Finder
If you can see the file now just delete it.
Then, switch back to visibles only and create a new folder called Startup Items.
defaults write com.apple.finder AppleShowAllFiles False; killall Finder
Or, simply creating a new Startup Items folder may be enough.

Problems with Deployment, Startup classes and MBeanHome

Hello,
we have the following problem: How to initialize our application
correctly???
We are using MDBs as message consumers but have to guarantee the order of
incoming
messages. Due to a shortcoming in the JMS implementation (Order of
redelivered messages
is not guaranteed before WLS 8.1!!!) we are using a singleton class to keep
the health state
of the different message queues within the application (controlling whether
the MDBs are
supposed to proceed with processing or to discard any incoming messages).
Thus the MDBs
have to access this singleton, what implies latter has to be initialized
prior to the application
deployment. That's what we are using a startup class for, which is marked to
be loaded before
appplication deployment...
Fortunately the according bug is fixed with WLS 7.0.2.0, so the class is
loaded, but we are
not able to access the MBeanHome interface (We like to register MBean to
provide
adminstrative access to the health state)!!!
javax.naming.NameNotFoundException: Unable to resolve
'weblogic.management.home.localhome' Resolved: 'weblogic.management'
Unresolved:'home' ; remaining name 'home.localhome'
at weblogic.rmi.internal.ServerRequest.sendReceive(ServerRequest.java:174)
So when is the MBeanServer started???
Before application deployment??? After??? Is there any way to tell WLS not
to load the startup
class before the MBeanServer is available respectively the MBeanHome is
accessible via JNDI
but before application deployment???
Any hints are welcome!!!
Regards,
CK

this seems like a bug. the mbeanhome should be available for lookup in
startup classes. also posting to system management newsgroup.

Startup class cannot find a config file.

I have written a startup class to configure log4j in Weblogic.
The class runs but cannot find the configuration file. The
code for the startup class is as follows....
package com.n2bb.ams.common.util;
import java.io.FileInputStream;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.Properties;
import com.n2bb.ams.common.util.FileLocator;
import org.apache.log4j.xml.DOMConfigurator;
* Insert the type's description here.
* Creation date: (12/5/00 11:12:13 AM)
* @author: Administrator
public class ApplicationStartUp implements weblogic.common.T3StartupDef {
     * ApplicationStartUp constructor comment.
     public ApplicationStartUp() {
          super();
     * setServices method comment.
     public void setServices(weblogic.common.T3ServicesDef arg1) {
     * startup method comment.
     public String startup(String arg1, java.util.Hashtable arg2) throws Exception {
          String resource = null;
          try {
               resource = (String) arg2.get("configFileName");
               System.out.println("ConfigFileName: " + resource);
               URL configFileResource = ApplicationStartUp.class.getResource(resource);
               System.out.println("configFileResource: " + configFileResource.toString());
               String file = configFileResource.getFile();
               DOMConfigurator.configure(file);
               return "Log4j configuration initialized completed.";
          } catch (Exception e) {
               System.out.println("Cannot open config file: " + resource);
               return "Log4j configuration failed to initialized.";
The section of the config.xml the calls my startup class looks
like....
<StartupClass
Arguments="configFileName=/bea/user_projects/mydomain/log4j-config.xml"
ClassName="com.n2bb.ams.common.util.ApplicationStartUp"
Name="AMS Startup Class" Targets="myserver"/>
I have tested the code in a standalone class and it works fine.
Why can't I find the log4j-config.xml file? Any help would be
greatly appreciated.

Wow, your system must have a long history of having picked up assorted bad stuff ...
You have CleanMyMac2, which should definitely be removed.
You have other stuff (MacCleanse, for example) that I don't have first-hand knowledge about but should very likely be removed.
You are using Google Chrome which is a resource hog.
Further, your Adobe Flash player is not current.
If I had all these issues, I would do a clean install of Yosemite and only reintroduce the essential stuff.
You can search for the .plist files by opening finder, holding down the Option key, and doing Go > Library from Finder's menu and then searching for the file(s).
