How to load classes at ejb module deployment

Hi,
Can someone tell me how to loaded a class when I deploy an ear module (the class is in the ear) ?
Thanks in advance.
Fred.

Hi Fred,
Can you explain your question a bit more? Are you asking how to do
dynamic class loading for your application or just how to package
classes appropriately?

How to Load Classes in run time - Urgent

Hi All,
How to Load a class file from a .jar file in JDK1.1 with out using URLClassLoader. I have tried to extract the .jar file by file input stream and zipEntry classes and defineClass using the bytes i got from the stream , but the class loader fails to take the classes that are already loaded in the system.
The customClassLoader that i created was not able to assign an object to the another reference variable that already in the JVM.Please i want to know how to assign or communicate between the objects of CustomclassLoader and SystemClassLoader?
Please help me in this regard.
Thanks in advance,

Hi,
The above code works in the straight way if the class is available in the classpath.
I need to load a class by using custom class loader that i extends from classloader base class .
I have to read a class file from a .jar file (in server) and load it in run time.Here i am able to read the bytes from the .jar file of the specified class file, but the class that i read extends some other class that is already loaded when i tried to create newInstance of the class i get Exceptions. Here the custom classLoader cannot find the loaded existing class in the JVM.can i get a solution for this situation

EJB Module deployed but encounters java.lang.ClassNotFoundException

Hi. I have successfully deployed my ejb in Weblogic 8.1 but I get still get the java.lang.ClassNotFoundException when I invoke the bean. The application will work only if i include the jar in the classpath in the startweblogic.cmd. However, this option displays the warning
<i><Warning> <EJB> <BEA-010001> <While deploying
EJB 'XXXBean', class XXXBeanHome was loaded from the system classpath. As a result, this class cannot be re
loaded while the server is running. To prevent this behavior in the future, make
sure the class is not located in the server classpath.>
.</i>
Is there something I forgot to configure in weblogic so I dont need to include the jar in the classpath? So I can also reload the jar while the server is running.
Any help is highly appreciated

I'll need more information to help you debug the ClassNotFoundException.
Can you show me the error message? And where is the class that it cannot find located?

How to load class from jar file dynamically?

After I run my Java applicatoin, I need configuring the classpath of jvm to load some classess inside a jar file into the same jvm.How can I achive that?
I mean, when I run my Java application, I don't know where the jar file is, what the jar file name is. All depends on the user to tell the jvm the details through some UI. I've tried to write: System.setProperty("java.class.path", "c:\myClass.jar");Class.forName("MyClass"); but failed.
Can you tell my why and how?
Thx

How to load classes dynamically?

Hi all!
I have folowing problem.
In my applet I need to load different classes form the same Web server. The main class is located in parent directory and different are in it's subdirectories. Security Manager allows to do this, but I find it difficult how to do it. Can you give me advise how to do it.
Thanks beforehand...

Create a package on the web side myserver.mypackage with subfolders ex1 ex2
THere place your class files to dynamical loading
Every class in package must starts from
package myserver.mypackage; statment
In paren directory for package creat a class where main applet class will be located
Create an inctance for submain classes as
(Class)Class.forName("myserver.mypackage.ex1.Class1").newInctance() - for class1 in ex1
(Class)Class.forName("myserver.mypackage.ex2.Class1").newInctance() - for class1 in ex2
It works. I'll send you example on e-mail.

How to load Class only once...

hi all,
i am using the Class.forName() to load the class.
the code looks like as follows :
for loop.....{
Class.forName("classA");
inside the for loop , is there any possiblity of knowing that the class is already loaded or not. i can load the class the outside the for loop . but i am curious to know how we can check whether the classA is already loaded or not for the next iteration of the loop.
tia,
dhanasekaran.

Class.forName() will only load a class that has not been previously loaded. Whether or not a class is already loaded is totally transparent to a Java application. It will be loaded as soon as it is referred to for the first time, be it instantiation or access to static members or a call to Class.forName().

How to load classes for a particular package

I have a package name say com.test
i need to get the names of all the classes starting with "Test" under this package. Also, i need to get the names of all the methods starting with "test" in each of these classes.
ideas/suggestions welcome :)
cheers
yogesh

Kaj,
thnx for ur time :)
i am developing a testing framework for our web applications. all our applications wd require to have com.test as the package which will contain all the JUnit test classes. the package name (com.test) will be provided by the tester thru a properties file. my framework will load all the classes (and also fetch the method names starting with "test" in those classes) and display them on a gui in a html form. the tester will just select the junit test cases he wants to run and my framework will expose this service thru a servlet. the servlet will then invoke all the methods selected by the tester via reflection.
if the way i want to do it is not possible cd u please suggest any alternatives ?
cheers

How to load Classes?

How to retrive the class name during runtime.....
suppose if i select java.lang package , i must get all the classes relating to lang package....
i used reflection API, but using that you can retrive constructor and methods of any class... and i need the classes of perticular package.... how to do it?
Thank You

Must it be in run-time? If no classloader tricks are applied, the whole class path contents could be perused to gain a list of the classes available there even berore running your application.

Application was deployed, but EJB module was not.

We use scripts to deploy an application to weblogic cluster. After deployment, there is no error and exception. But, in related weblogic log, there is no information about EJB module deployment.
On weblogic console, the EJB jar is presented at the left pane. After check the targets of the EJB jar, we found the EJB jar was not deployed on any weblogic server in the cluster. But two war packages are deployed successfully.
There is no error in applicaton.xml and EJB deployment descriptor files. And this issue just happened in one environment. In other environments, no such an issue. Could any points make this happen?
Thanks.

we faced same issue after redeploy the app. Via console, it is ok.
before this redeployment, the app is just a web application, no EJB module. in this release we added an EJB module into this app. And use the same script to redeploy.
below is the script snippet to deploy and redeploy an app. The option -targets is not identified in the redeployment process. Could this be the problem?
if test REDEPLOY -eq 0
then
# first deployment
echo "\nFirst deployment for $APP\n"
${WLS_DEPLOY_CMD} -verbose -name $APP -targets "$TARGET" -source ${WLS_HOME}/applications/${APP}/${APP}.ear -deploy
EXIT_STATUS=$?
FIRST="(1)"
else
# redeployment
echo "\nRedeployment for $APP\n"
${WLS_DEPLOY_CMD} -verbose -name $APP -redeploy
EXIT_STATUS=$?
FIRST=""
fi

Unable to load the EJB module. DeploymentContext does not contain any EJB.

I'm writing an enterprise application to familiarize myself with Glassfish 3.1.2 and EJB 3.1. I've created several local, stateless beans, and injected one into a JSF managed bean. The ejb and web modules compile fine, but when I launch the application with Glassfish I get the following startup error and the application does not deploy. I don't understand what it means, can someone ellaborate?
SEVERE: Exception while invoking class org.glassfish.ejb.startup.EjbDeployer prepare method
SEVERE: Exception while invoking class org.glassfish.javaee.full.deployment.EarDeployer prepare method

If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected

My guess is that you deployed an ejb without bean in it. when you have an ejb module, be sure you have at least one bean present.
Are you sure you have implementend some beans? Or did you do this only in the web module?
Try adding an @Stateless bean doing nothing in you ejb module, redeploy and let me know if that works

How to reference an External Library (Server Side) in a DC-EJB Module ?

Hi:
I start working with hibernate in a DC component, so I create my DC project and EJB module inside. I Make an external library following this
Thanks a lot for your time on this thread.
Rocío.

Hi Rocío!
Umm, I don't usually use DC's... I don't know if this will work... you can make an EAR (New Proyect -> J2EE -> Enterpise Application Module), add your EJB Module to the EAR (right click on EJB Project and choose Add to EAR proyect), and you'll find a j2ee-engine file on it, and you can add the reference there.Then deploy the EAR.
I normally do something similar to your issue, I make a EJB calling XI via Java Proxys, and the reference to the XI libs are allocated on the EAR, not on the EJB. This is only for runtime, for compilation you must reference the hibernate jar with an external jar file, as always.
A dirty solution could be this one: open your generated EAR with de-compressor, and copy your hibernate jar on it (at root). This way you'll load hibernate classes at runtime (I know this is an horrible solution, this is only for testing).
As I said before, I'm not used to DCs, so this could be wrong, and be a waste of time... I don't know further...
Good luck
Eneko.
