Startup tasks won't work in startup class

Hi,
I need to do some work at system startup and shutdown that
doesn't quite fit the WLS startup/shutdown model. In both cases,
I need to talk to the WLS web server but it's not listening until
after the startup classes are run and stops listening before the
shutdown classes are run.
I'm thinking about using a servlet init() for my one-shot startup
but don't know how robust a solution that is. And I don't know
what to do about shutdown. Is there a startup/shutdown hook
associated with container loading/unloading? Some other solution?
I'm using WLS 6.1 SP2.
Thanks, Garry

startup/shutdown tasks, you can use ServletContextListener instead.
Using one of those is definitely better than startup classes.

But when I configured the servlet in the default-web-app the startup class is running.

IMac G5 iSight freezes on startup - CDs won't work

Hi everyone.
My iMac G5 iSight is freezing up on startup. It was running slowly and erratically, so I restarted it - ever since it has failed to start up.
It gets though the basic hardware check and gets to a point where there is the big apple logo and the circular pulsing thing that suggests it is loading - however it never gets any further.
I tried loading with a CD holding the c key -but that won't work. The CD drive revs up, but it gets stuck at the same location.
I've zapped the PRAM several times (twice each). No effect.
I've disconnected the keyboard and all peripherals.
I've removed the memory module I added 2 years ago.
So, I'm stuck. It doesn't look like complete hardware failure - or it wouldn't get as far is it does.
Is there any other way to force a reset of some kind that will allow me to boot from a CD?
Thanks in Advance.

Check the Repair extension programs and look for your number. Whether you qualify also depends on how old your computer is. The extension cuts off three years after the original purchase date, but they have been known to make exceptions.

ICal Crashing after startup; iTunes won't work

My problem is twofold:
My iCal calender (desktop) crashes upon opening every time. I reinstalled Tiger (from "not for resale discs" supplied by Apple). It did not fix the crashing; I still can't use iCal. Now, iTunes won't work with this installation of Mac OSX.
I deleted iCal and reinstalled the OS again and I have the same results. Coincidentally, this crash happened after I upgraded to the iPhone 3Gs.
Can anyone help me?

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.

Startup Classes and JMS - Suggestions Please!

I'm in serious need of having several resources initialized before beans
start handling requests.
I tried implementing a Weblogic Startup Class, and it works fine - as long
as it's the first thing
to run! -- the problem is, when my Message Driven Beans deploy, if there are
messages waiting
for them in their durable subscriptions, they immediately start
processing... then about 30 seconds
later Weblogic (6.0sp1) gets around to starting my startup class. If I put
code in each MDB that
kicks off the initialization when they are invoked I still run into
problems, because my initialization
takes a LONG time (more than 2 minutes) - so I end up with lots of
transaction rollbacks... which
are very annoying and clutter up the log files, and scare customers of the
product.
Is there anyway to make a startup class/servlet/something that runs and
completes before any
other processing occurs?
Thanks,
James

Yes, Startup servlet has the same problem - it doesn't 'startup' until after
jms messages are already being delivered. :( aside from this, there are
class loader issues -servlet space and ejb space are not the same...
Thanks though,
James

James,
If you have common initialization tasks to be shared by multiple MDBs,
I
would create an abstract class (a.k.a BeanAdapter class) where you canhave
all your initialization logics and have your MDB extend from it.
I am not convinced that the Startup class needs to run first. In fact,
I
have the same view that Startup class should run last. My only wishlist
for
startup class was that I should be able to specify order, which isaddressed
in 6.1.
I am also getting the feeling from different posts that MDB deploymentwould
have a re-try logic in 6.1, which I am beginning to look into. Check
(or
post) in JMS news group.

James,
There are several ways to solve your problem. I normally use
setMessageDrivenContext to do all my initialization. There are two
types
of
initialization that I have performed here, first, reading theconfiguration
file and then load some utility classes in specific order. The
problem
with
the second was that you will have to use synchronized block
w/HotSpot
2.0
to
keep the order, which is ok. I don't use static block to do the
initialization, instead use an init() metod. Hopefully you got the
idea.
Recently, Gene Chuang created a pattern which esentially does the
same
and
I
liked the pattern because it was a nicer way of doing what I
needed to
do.
I
have changed all my examples to customer to use the new pattern.
You
can
find it in
http://theserverside.com/patterns/thread.jsp?thread_id=7270.
The
only think I do not use of this pattern is
initializeEveryContextSwap()
method. I am not convinced yet that I would need it (of course
that
might
change over the time).
Hope this helps, and thanks Gene.

Ok... here's some more detail:
The application is largely JMS based, and most of my Session
EJBs
are
invoked only my Message Driven Beans.
I have a large set of properties that need to be read from a
config
file,
and stored somewhere "globally". I also have a number of
utilities
that
need to get "warmed up" before I start doing any real processing(before
I start receiving messages from the JMS Topics). These
utilities
take
a
long time to warm up (a long time being about 45-60 seconds) -
because
they are loading hundereds of classes, and creating variousconnections
to external resources.
Currently I'm creating a Singleton object that reads the
configuration
file
name from an environment property, and it then parses the file,
and
starts
configuring all of these utilities. Since the "Startup Class"
didn't
work
(weblogic invokes it after I'm already receiving messages), I
put
code
at
the beginning of all of my MDB's onMessage() methods that calls
the
singleton's "getInstance()" method - which synchronizes on alock
object,
and does all of it's work.
I don't like this solution because:
1- I have to put code in EVERY message-driven bean that I
create -
if
I
forget one, everything is broken.
2- I have to increase the transaction time out of the entire
server
to
be over 60 seconds since the beans hang that long while theconfiguration
is
happening.
It seems very obvious that a "Startup Class" should be invoked
after
the
server has come completely up, but before it starts listening
for
requests -- isn't the whole point of a "startup class" to getthings
ready
that need to be done as soon as the server comes up? but alas,
the
person
who designed this at BEA apparently didn't agree with me on this
point!
Any suggestion on better solutions would be greatly appreciated.

You can do it this way, but I would not recommend it, unless
that's
the
only
way to attack the problem at hand. But that's just me.
I have seen this problem with multiple clients and in most
cases
there
is
a
better way to handle it. If James give us a little more
information
on
what
type of configuration is he talking about and some background
of
his
application, we as a group can think and may be able to come
up
with
some
idea.

you could wrap the starting of weblogic in your own class
and do
initialization
there. You have to be careful because of the way weblogic
classloaders
work, but
you may be able to do what you want. Weblogic is just a java
class,
so
you
can
start your class, then once your done initializing, just
call
weblogic.Server.main

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

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

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.

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.

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).

Static methods in startup class

I have declared few static methods in startup class. What will happen
          once startup class is executed in cluster environment, will the access
          to those static methods be clustered and replicated across the
          clusters. How exactly the startup class behaves in clustered
          environment.
          I will appreciate an urgent response.
          Thanks,
          SidShar .

          No.
          > How exactly the startup class behaves in clustered environment.
          It is run on each server that it is configured to run on. The method calls
          to the startup class will all be local unless you do some special work to
          force it to be otherwise.
          If you want to have something done once and only once in the cluster, or
          coordinate stuff like that, then either use a shared resource (such as the
          database) to coordinate it all, or use Coherence, which lets you share and
          coordinate access to data among all the servers in the app tier.
          Peace,

Weblogic Startup Class does not run as Windows Service

If you know the answer, plase send me an email at [email protected]
I'm running a weblogic startup class that starts a Thread. I need to
run a batch program that should be running as long as WebLogic is
running (to process new orders).
It works fine when I run WebLogic (5.1 SP8) from a script, but causes
problem when I'm running it as a Windows Service. It calls the
startup class, however, the startup class never spawns the Thread
class.
Following is excerpts from different components:
=============================================================
*** weblogic.properties ***
weblogic.system.startupClass.pdfCreatorStart=WebLogicStartupPdfCreator
*** WebLogicStartupPdfCreator.java ***
public class WebLogicStartupPdfCreator implements T3StartupDef {
public String startup(String name, Hashtable args) throws
Exception {
Thread t = new ProductionPdfBatchRunner();
t.start();
return "success";
*** ProductionPdfBatchRunner.java ***
public class ProductionPdfBatchRunner extends Thread {
public void run() {
try {
//work being done here
this.sleep(30000);
catch (InterruptedException ie) {
catch(Exception e) {
e.printStackTrace();
=============================================================
Thanks for any help

Hi,
Ok. Few suggestions.
1. Can you review the SAP note:
552286 Troubleshooting for the SAP Web Dispatcher
2. When you said: "web dispatcher does not get started ", what error you got ? Can you be more details here ?
3. Please check the trace file dev_webdisp" that generated in the work directory. If the log entries is not abvious, increase the trace level to 2 or 3, and reproduce and re-check the trace file.
4. What is the output of the command "sapwebdisp -v"
5. How about sapwebdisp.pfl ? Are those settings correct ?
Hope this helps.
Regards,
Vincent

Startup class : Context lookup for a Home fails in a new thread

Hi All,
I am having a funny problem with Weblogic Startup class.In the startup method,
I am creating an instance of InitialContext. I called look up in this context
for a bean's home. It works and it retuns the proper Home interface.
But, when I use the same InitialContext instance in a new thread, and again if
I call look up for the same bean's home, the server fails with a SecurityException.
I don't have any Role based Security for this bean.
Btw, I am using Weblogic 5.1 & SP7.
Any ideas or help, appreciated..
Thanks in Advance

Error when starting opmn with custom startup class

I'm trying to use jaxb 2.0 classes in my custom oc4j startup class, but when I try to start the container the following error is produced in the logs.
Exception in thread "OC4J Launcher" java.lang.IllegalAccessError: tried to access class javax.xml.bind.ContextFinder from class javax.xml.bind.JAXBContext
Can anyone provide some guidance?
Regards,

It seems I trying to use jaxb 2.x classes but oas 10.1.3.5 uses jaxb 1.0. Is there anyway to get this to work with jaxb 2.x? The error message I'm receiving now is

How to implement Startup class for OC4J

I'm in the process of converting my current J2EE application from weblogic 5.1 to OC4J.
I have startup class that would set application specific properties by reading property file. In addition, this class would also check for certain resource availability (like database) during weblogic startup. I could not find similar option in OC4J.
Any help to convert this startup class for OC4J would be highly appreciated.
Thanks
Sankaran.

Hi Sankaran,
Your eMail address suggests you work for Oracle. Do you? Can't someone
at Oracle help you?
I imagine that Oracle would have some kind of agreement with Ironflare
as well. Can't someone at Ironflare help you?
But remember, with application servers (as with RDBMSs), no two are the
same. Each one offers the same functionality, but using different methods
to achieve that functionality. I don't know how to do it, but I'm sure
you can check database availability when starting up OC4J -- just not
the same way you do it in Weblogic.
Good Luck,
Avi.
