Weblogic Startup Class

Hello,
I need to set up a start up class for quartz jobs in my weblogic server.
I have created the startup class from the weblogic console but i dont know where to put the class or java file.
Where is it read from?

Hi,
Is it possible to use Weblogic startup class to initialize client's SSL channels?
Any pointers are appreciated.
Thanks in advance.

Hey
If possible can you explain the issue in detail.
What do you mean by “initialize client's SSL channels”

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) {

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.

Vincent

Weblogic startup class (urgent)

Hi All,
I need a java program (weblogic startup class) which should fetch data from the database and instantiate another one class (it will be the data holder) and store that object into a webapplication context. Anyone tried this? Since its urgent any help will be appreciated.
Thanks in advance

Do this in the init() method of a servlet and start
the servlet when you start your weblogic server
second that. just give a value of 1 for <load-on-startup> in web.xml

Weblogic startup class and EAR file

Hi,
I am using WL 8.1.5.
I have a weblogic starup class MyStartup that implements T3StartupDef. (it does not specify package).
I jar-ed it. And I placed MyStartup.jar file into the MyEA.ear file. And I placed that into applications dir.
With WL Console I defined the startup class and for the ClassName specified MyStartup.
Yet I get the java.lang.ClassNotFoundException.
I also have a Manifest.mf file with
Class-Path: MyStartup.jar
Please help me solve this problem, I literally don't know what to do next.
MB

Hi,
thanks.
This seems like a completely opposite method of the depplying startup class with weblogic console.
Does my class still need to implement T3StartupDef?
I get this exception. And my classnotfound is still there.

Weblogic startup class: problem calling EJB's

Has anyone ever experienced a problem in using a startup class (registered in weblogic.properties)
and tried to lookup and use an EJB in the same application?
Basically, I have a startup class which registers to receive messages from an
MQ queue, and when it receives a message, it tries to do a lookup of a bean and
use it, but I receive a 'NullPointerException'.
I'm running Weblogic 5.1
(I know that Weblogic 6.0 makes use of MessageDrivenBeans, but my app isn't using
6 or EJB 2.0)
Thanks...

Can you post weblogic.log? Are you sure that EJB was deployed successfully.
Also comment the PROVIDER_URL in initial context and see if that solves the problem

The exception is simply a 'NullPointerException' coming from the startup class

when my startup class receives a call to the onMessage(...) method (from listening
for messages), it looks up an EJB on the server, through the InitialContect class
and gets a 'null' returned back, thereby throwing the NullPointerException.
If anyone else is successful in having a startup class which can lookup and call
an EJB within the same Weblogic server, please help.
Thanks again....

Configure weblogic startup class in deployment jar

We need to invoke a class during weblogic startup that is part of application deployment jar...
It works if startup class is added to server classpath ( Weblogic documentation also insists that). But our startup class uses application logic and needs to be part of application jar..
We are getting java.lang.ClassNotFoundException for the class during start up. setting LoadBeforeAppDeployments to false also does not help...
Is there any other way to invoke a application class during weblogic startup...?
Any help would be appreciated.
Thanks,
Rajasekar.

here is the solution to this:
in the conventional method of implementing a startup class, one needs to impletent the T3STartupDef interface and register the class as a startup class in the console / config.xml
in this method, the startup class need not implement the T3STartupDef interface, it just needs to have a "main" method that will be called. the process of registeration is also simple, if you have an application ear.
while making the application ear, add a weblogic-application.xml along with the application.xml. the weblogic-application.xml should contain :
<startup>
<startup-class>myStartup</startup-class>
<startup-uri>myStartupArchive.jar</startup-uri>
</startup>
the myStartupArchive.jar should contain the startup class and all classes used by it
also, use a "manifest" file to point to other library jars within the ear
hope this helps someone !

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..

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,
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

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

type of configuration is he talking about and some background

you could wrap the starting of weblogic in your own class

there. You have to be careful because of the way weblogic

work, but
you may be able to do what you want. Weblogic is just a java
class,
so
you

Startup classes in WL6.0

Hi everybody,
Is the use of T3StartupDef interface deprecated in
weblogic 6.0 for writing startup classes? If yes how do I write startup classes?
Thanx,
Sunil

One feature of WebLogic startup classes is that you do not have to implement
T3StartupDef - if you class has static void main(String[] args) it will be
invoked.
Also, note that startup classes have to be in the system classpath, which
creates problems when they need to use application classes.

Startup classes using the T3StartupDef interface do work in WebLogic
6.0 - I am
just now porting a project from WL 4.5 to WL 6.0 and got it to work okay,

with these caveats:
(1) BEA's Javadoc documentation on the T3StartupDef interface is outdated
- it

by
config.xml and the Web-based Admin console).
(2) BEA's documentation for configuring startup classes in the Admin
console is
poor - for the 'Arguments' attribute, it doesn't specify how to format
arguments
for the startup class - you separate them with a comma like this:
ARG1=value1,ARG2=value2
(3) There is no documentation on how to write a Startup class in the
programming
section of BEA's documentation. It's very simple though; here is what
you do:
(a) Write a class that implements T3StartupDef.
(b) Give it a default, do-nothing constructor.
(c) Provide the interface's #setServices(T3ServicesDef) method - just
save the
parm in a field or something.
(d) Provide the interface's #startup(String, Hashtable) method - the
Hashtable
contains your arguments (set in the Admin console) and this is where
you put your
desired startup code.

Startup class is run before web services are deployed

Hello, I need to run a class at server start-up which uses web services deployed on the same Weblogic server.
I'm using Weblogic startup class, which fires after the server is up and all modules have been deployed.
However, it is fired before web services are deployed, so this solution doesn't work.
Is there a way to have a class that is run by Weblogic after web services are deployed?
Right now I'm using a timer that polls the server till the services are up and running, but I hope there's a cleaner way.
thanx,
Mike

Thanx for response.
Looking at the logs, the following came to light.
1. My app does get deployed last, but the ServletContextListener in my app is fired after all modules "...transitioned from STATE_PREPARED to STATE_ADMIN".
It took a few more seconds for all modules to transition "from STATE_ADMIN to STATE_ACTIVE".
2. After all modules transitioned to STATE_ACTIVE, the log shows this:
<Channel "DefaultSecure" is now listening on xxx.xxx.xxx.xxx:443 for protocols iiops, t3s, ldaps, https.>
I assume that only at this point are web services accessible. The error that I get when trying to invoke a web service from ServletContextListener is:
java.net.ConnectException: Tried all: 1 addresses, but could not connect over HTTPS to server: RLOCVGVY91 port: 443
at weblogic.net.http.HttpsClient.openServer(HttpsClient.java:289)
So I dunno... If my ServletContextListener waits for 10 seconds, everything works.

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 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
some one help me out ?.
Thanks,
S Gopikrishna

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

Clustering of startup classes in WebLogic

          Hi
          WE have an application running as startup class in WLS 6.1 . I want to know
          how this class can be deployed in clustered environment. Iam pretty ne to clustering
          . Can some body help me out ?.
          Thanks in advance,
          S Gopikrishna


I don't know what you mean.
          If you want each instance of your app to be running something, you should
          use a load-on-startup Servlet with its init() method instead of a startup
          class.
          If you want each instance of a server (not each instance of your app, since
          an app can be loaded multiple times on a server) to be running something,
          you should use a startup class.
          If you want exactly one instance in a cluster to be running something ...
          well, good luck. There's no guarantees in this regard, but the easiest way
          is to pin it to one server and make sure that that server never goes down
          because it is a single point of failure.

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.

Please help me in resolving this problem. I need it asap
Thanks,

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

Hi,
I am beggining to upgrade our app from Weblogic 5.1 to 6.0. So far it
has been progressing nicely and everything works with one exception. I
can not get the start up classes to run. I get the following exception:
<Failed to invoke startup class "MyStartup Class",
java.lang.ClassNotFoundException:
followed by my fully qualified class name. The class is reference
elsewhere in the code and works fine. Is a seperate classpath used for
startup classes? If not why might Weblogic have a hard time finding my
class?
Thanks,
