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.
Exception:weblogic.management.ApplicationException: startup.MyStartup

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,
JamesYes, 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 could wrap the starting of weblogic in your own class

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

Porting *.war files and *.ear files to Weblogic 10.3
If we can figure this issue out, I'll see if I can't publish/post a
maven-based solution in the Maven and Oracle forums so that others
will not have to go through our pain.
We are having all the usual problems regarding where Weblogic expects
to find things and what exclusions need to be made in weblogic.xml for
war files and weblogic-application.xml for ear files. Any insights
would be deeply appreciated.
Here is what our exploded war structure currently looks like.

The exception above repeats for every .class file found below
WEB-INF/classes/com, i.e. the the ones in this module rather than the
ones in included modules.
Checking the file system shows that there is no such directory as
"appmergegen_1254502686535_conap". I'm uncertain if there is actually
supposed to be anything there, but it would seem like it.
I've a theory that if we can solve the above issue, we can solve the
rest ourselves.
It would also be handy to know what packages may cause conflicts.Alright, my research points to the idea that this might have something to do with staging. Since this is a dev setup we don't have any managed servers or anything. All we have is AdminServer and that is it. We have only one domain and it is "base_domain". Does anyone know if this is wrong?

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 !

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 helpHi,
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.

Difference between .jar, .war and .ear file
Hi,
I am pretty new to J2EE technology.
I would like to know what is the difference between .jar, .war and .ear files and how they are deployed on webserver.
Thanks,Files with a .jar extension or JAR files, are essentially just a collection of files compressed using the ZIP/ZLIB compression format.
JAR (short for Java Archive) files were introduced in the early days of Java as a means to conveniently package and distribute Java applications and components. Since then, a number of additions to the Java platform have followed suit. The introduction of the EAR file is one such addition.
An EAR (Enterprise Archive) file is a JAR file that contains a J2EE application.
A J2EE application is a group of Web modules that collectively perform as a single entity.
A Web Module is an entity consisting of one or more resources such as HTML files, Java class files, XML files, etc. Web Modules are packaged in Web Archive (WAR) files.
Looking at it from a top-down view, EAR files contain JAR files and WAR files. Packaging resources in WAR files, JAR files and eventually EAR files, makes it easy to reuse and reassemble components as new J2EE applications and distribute them to new environments.
For example, Tomcat deals only with WAR files.
So, in order to auto-deploy a Web application to a Tomcat environment, you must place an application's WAR file in the appropriate directory or use Tomcat's deployment tools to manually deploy the file.
If you already have an EAR file that contains the WAR file, you can extract the WAR file and use it as is. If you do not have the EAR file or the WAR file, you can use any number of compliant tools to create the WAR file. Tomcat is a servlet/JSP container available from the jakarta.apache.org site. -

Difference between .war file and .ear file
Hi,
what is the difference between .war file and .ear file ?
Please let me know with appropriate explanation.War file means web application archive. It is archived file having a collection of JSP, servlets and static pages that together costitute a web application. It contains one WEB-INF directory which will have a file named web.xml which defines the structure of the web application.
On the other side EAR file is Enterprise application archive. It is file having packaged content of one or more modules into a single archive so that the deployment of all the modules can be done simultaneously on the application server. It also contains XML files called deployment descriptors which gives the details of the deployment method. This deployment descriptor will be present in the folder META-INF folder.
So the main difference betwwen the two is that Ear file is having collection of various modules to be deployed on the application server while the WAR file is used to deploy the web applications. -
Weblogic startup class: problem calling EJB's

use it, but I receive a 'NullPointerException'.

Also comment the PROVIDER_URL in initial context and see if that solves the problem

Deployment and .ear files
I have two questions; one may relate to the other.
First, I would like to know the best way to deploy Session beans which have dependencies on other EJBs, be they Entity Beans or other Session Beans. The dependency is limited to the implementation class, not the interfaces. I have tried just putting all my EJBs in the classpath in startWebLogic.sh, but I get the "bean cannot be redeployed while the server is running" warning. Is there another way?
Second, I have read of .ear files, which seem to be a good way of dealing with many EJBs/JSPs en masse(I'm working with ~100 EJBs and ~2000 JSPs). However, I haven't found anything on exactly what they are, how to use them, or how to generate them.
If anyone has these answers, or can point me to a good site on the matter, I'd appreciate it.
Thanks, --Tom SeufertHi Tom,
The "best" way to generate EAR files is to use an IDE that has built-in
tools to do it -OR- to use ANT (kind of an xml-based gnu-make-like utility
for Java).
Most dev groups that I've seen start by using .sh/.cmd (i.e. batch) files to
generate the JAR/WAR/EAR files. ANT allows you to do things like
dependency-based builds, to avoid re-generating parts that are not
necessary. That was very handy with WL 5.1 when EJBC could take several
minutes (even running locally with a fast compiler like JIKES). (I have
only used ANT a tiny bit, but Jesse Tilly who frequents this newsgroup is an
expert with it.)
The EAR is just a means to bundle different parts of your application
together. For example, your EJBs will be bundled into a JAR, and your JSPs
will be bundled into a WAR, and you can put both into an EAR. WL6.0 will
accept an EAR file for deployment, will auto-deploy, and will even re-deploy
it if the EAR changes!
The easiest way to build a JAR or WAR or EAR file within a batch or build
file is to use the JAR command. If you have a directory structure that is
exactly how the JAR file will be layed out, then I believe the command is
"jar -cfm0 my.jar *" or "jar -cfm0 my.jar .".
