EJBs in classpath

Hi!
Is it possible to make the JEE container deploy EJBs in JARs available in the classpath of an EJB module? For example:
common.jar
- /com/mycompany/MyEJB1.class
- /com/mycompany/MyEJB2.class
myejbmodule.jar (references stuff in common.jar)
- /com/mycompany/MyEJB3.class
- /com/mycompany/MyEJB4.class
In this instance, I'd like to include "myejbmodule.jar" as an EJB-module in the app, but I'd like to avoid deploying "common.jar" as an EJB-module. Still, I'd like all EJBs to be deployed. Is this possible? Using JBoss 4.2.2.
Thanks in advance,
Nille

Copy the Ejb jar file to the applications dir.

Redeployment - EJBs on Classpath

I'm using wls 8.1. I have an EAR in which several EJB are loaded from the system
classpath. After redeployment, these EJB's are not available.
java.rmi.NoSuchObjectException: Bean is already undeployed
I would have expected not to be able to affect any change in such EJBs via redeployment,
but that redeployment would be successful. The console shows that redeployment
for these EJBs is successful (i.e., status: active). Do these classes have to
be off the classpath for redeployment to work properly? Why doesn't the console
report their status correctly? Thanks...

I believe you are right. Unfortunately the calling application isnot really
a client but the security provider. So, I've put everything our realmcode needs
on the server's classpath. I've also tried taking it off the classpathand putting
it in the providers.jar, but no joy. In that case, a ClassCast exceptionis thrown
on the narrow. So, my problem seems to be that I don't know how tohandle the
situation where my login module makes EJB calls. Is there any wayto refresh
the providers.jar?Does your security provider cache the EJB stub? I believe if you
re-lookup the home in JNDI and get a new stub that it should work fine
without refreshing the providers.jar (assuming the new EJB didn't change
the interface.)
Yes, I am (was) caching the stub. Yes, re-looking up the home cures the problem.

EJB Classpath Question

Hi,
I have a burning question regarding EJBs and classpaths.
Here is my situation:
- My application uses EJBs, Servlets and JSP pages
- My EJB remote interfaces and implementation classes extend common,
abstract base classes
- My EJB implementation classes use several utility classes, which are
also used by my servlets.
- Each EJB is deployed in a separate JAR file
The question I have is which classes should be included in the EJB JAR
files.
I'd like to put just the EJB implementation class in the EJB JAR, and
put everything else in a common JAR that is placed in my WEB-INF/lib
folder and shared by the rest of the application. However, if I do
that, Weblogic won't load the EJBs because it tries to do so before it
deploys my web app, and hence before it adds the JARs in the
WEB-INF/lib folder to its classpath.
I can explicitly add my jar to the Weblogic classpath on the
commandline (weblogic.class.path property). Now my EJBs load. However,
my servlets become unable to load any classes from any jar in
WEB-INF/lib. I read something about it being a bad idea to include a
jar from WEB-INF/lib in the classpath, so I'm probably seeing that
problem.
The third option is to include all the dependent classes in my EJB
jars themselves, in addition to deploying them in WEB-INF/lib. This
works, but it bothers me that there are multiple copies of the same
class files lying around.
I'm sure I'm not the first developer who's written an EJB that shares
classes with a servlet or JSP page. What's the proper way to do this?
Thanks.

Use a ClassPath entry in your EJB jar module MANIFEST.MF file

Call ejb from browsers

Hello Developers!
I deployed my ejb to OAS4081. I call that
from JDeveloper so it good. But when I try
to call from applet in IExpl5 I can't
instantiate the ORB. I've got a com.ms.security.SecurityException : oracle.oas.orb.CORBA.ORB.init
I coded the CLASSPATH(oasoorb(yoj),client,
ejbapi...) perfectly, I think.
If anybody could help, please...
Thanx!

Hi there,
 I saw someone on this group had a problem to locate proper classpath
 to call EJB from JSP. I thought if you call EJB from classpath, you are
 calling the bean. But you loss all the EJB functions. To be able to utilize
 EJB features like object pooling. You need to call it from Weblogic server
 using url/jndi, not from the jar directly.
 Any comment? Am I right?
 BTW, my question about calling EJB from JSP means calling through URL,
 not a local path.
 Thank you

EJB and Jdk1.5 problem

We are trying to migrate jdk 1.4 (wl 8.1) to jdk1.5 (wl 9.1), when we complie Java source code and build EJB ( using Ant/build.xml), we got following error and can not proceed any further.
[java] /home/fipdev/DeltaOne/newproductimport/ejbcgen/com/leh/deltaone/ejb/business/newproductimport/DONewProductImportAccessor_41o8gs_Impl.java:12: cannot access com.leh.deltaone.ejb.business.newproductimport.DONewProductImportAccessorBean

[java] extends DONewProductImportAccessorBean
[java] ^
[java] 1 error
[java] Exec failed .. exiting
[java] Java Result: 1
49.0 means using jdk1.5 and 48.0 means using jdk1.4, we do use jdk 1.5 in our development server and could verify by
bash-2.03$ java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed mode)
do you know why?
Michael Zou

Much appreciated your reply, I used both Windows and Unix system and Ant to build EJB, both CLASSPATH and PATH are configured to Jdk 1.5 version.
CLASSPATH=C:\bea\jdk150_06\lib and PATH=C:\bea\jdk150_06\bin, and verify that it is 1.5 not 1.4 version.
C:\Eclipse_WorkSpace\DeltaOne\ant>java -version
java version "1.5.0_16"

but still getting error, any an idea? thank you again.

this ejb-jar.xml only contains entries for session beans? where did the entries for entity beans went?Ive written XDoclet tags for the Entity Bean as what ive posted above....help!!!

you comment the generation of CMP entity beans out :
build.xml:
replace

with
<entitycmp/>i've already removed the comments of the tag <entitycmp> and yet the resulting ejb-jar.xml contains no <entity> tags....i'm just wondering how can i include the generation of entity tags (not only session tags) in the resulting ejb-jar.xml

No name found Exception when running entity client program?

Hi
I am deployed an bean managed Entity bean successfully. And also i created one table in SQL . I am usung weblogic server 8.1 . while running Bean managed entity bean client program it throws no name found exception.please guide me how to run a entity client program. i configured JDBC driver for SQL successfully.
Regards
Priya.M

Hi Priya,
Before running the ejb client we need to follow the steps as given below.
1)set the weblogic environment using the setWLSEnv
2)set the classpath for ejb(home,remote and bean).
3)run the client program
Note:To set the classpath for the ejb(suppose if we placed the ejb's in ejb folder)
set classpath=d:\ejb;.; %classpath%

Regards,
Henning Storhaug

There is a little bit of situation using taskdef and a classpath from inside
a build.xml. The problem is that ant creates a custom classloader (which
loads classes the same way ant finds files, ie. replacing /->\, :->;, using
the correct basedir, etc. etc.). Ant uses this classloader to load the class
implementing the task.
Mainly this creates two problems:
- This classloader does not 100% implement the correct protocol of a
classloader, especially when it comes to finding resources. (no disrespect
intended, ant is a great tool!)
- Many classes in Weblogic is not really used to being loaded from a
classloader and doesn't behave very well. (for example: using the
system-classloader directly, assuming that they are located at the
java.system.classpath etc. etc)
This makes it almost impossible to use any weblogic-tasks without loading
weblogic-classes from the system-classpath. And that is why the "trick of
the external build.xml" works, because antcall starts the new ant with a
system-classpath including weblogic.jar.
Don't really now what the best solution to this is. I think that BEA has to
be better writing code that behaves nicer to custom classloaders, and I
think the ant team needs to fix their class-loader a little better.
(especially in respect to resources)
In the meantime use the "external build.xml"-trick or use the ant included
with weblogic.

We are actually using Ant 1.4 with Weblogic 6.1 and the wsgen tasksuccessfully..
although I haven't tested myself , I was told that there might be problemsif
the wsgen task is run from the same build.xml file (which might be thereason
for your problem as well)... so what I have done is created a second buildxml
file that includes the wsgen task (and some staging tasks) and I call itfrom
my main build.xml (using antcall).
A couple of things to note is that you have to make sure that you put antin front
of the weblogic.jar in the classpath.. Additionally (and you were rightabout
this) you have to use the taskdef to define the wsgen task as ant will notfind
it by itself..
Here is a sample of the wsgen task I use.
<wsgendestpath="${dir.dsn-build}/webservices_staging/${module.name.Report}WS.ear"
>
context="/${module.name.Report}"
host="localhost"
port="8081"
protocol="http"
webapp="${module.name.Report}-web-services.war">
<rpcservices path="${dir.ear_staging}/ReportEntryEJB.jar">
<rpcservice bean="ReportEntry" uri="/${module.name.Report}uri"/>
</rpcservices>
</wsgen>

bea.class.path was defined to ensure that weblogic.jar came first.
However, I got a curious error when running wsgen target - can't
remember,
and
don't have, the full details - but it involved a message along the lines
of something
"...violating loader constraints...".
So I just gave up and used the version of Ant that ships with WLS 6.1,
and it
works and I am happy and content.
(But you're stuffed if you want to move to ant 1.4)

The wsgen ant-task runs when using the ant-distribution within

not using the jakarta-ant-1.3 distribution. I've checked the versions,

Client program not compiling?

Hi
I am using Weblogic server 8.1 for EJB applications.
I deployed simple session ejb program,i successfully deployed ,but client program not compiling it doesn't take home and remote interface.
How to set classpath for client program,before compiling a client.
for example i had client in this dir
D:\ejb\
ejbclient.jar
client.java
bye

Hi,
Before running the ejb client we need to follow the steps as given below.
1)set the weblogic environment using the setWLSEnv
2)set the classpath for ejb(home,remote and bean).
3)run the client program
Note:To set the classpath for the ejb
set classpath=d:\ejb;.; %classpath%

Weblogic 8.1 and exploded EAR application

I have been trying to deploy my eclipse j2ee project in exploded way in weblogic 8.1
I have standard folder structure,
<APP_ROOT>
-> index.jsps etc.
-> WEB-INF/classes
-> APP-INF/lib (for 3rd party libs)
META-INF/ application.xmls and ejb-jar xmls. Now problem is, i am not able to deploy ejbs using classpath WEB-INF/classes.
I tried MANIFEST.MF class-path entry, it didn't work.
Is there any way to define classpath for ejbs at application classloader level?
Ofcourse, if I create new folder say 'ejb' and deploy that as ejb module and put all classes in ejb directory, it works.
my application.xml looks like this
<application>
<display-name>Test Application</display-name>
<module>
<ejb>/</ejb>
</module>
<module>
<web>
<web-uri>/</web-uri>
<context-root>webapp</context-root>
</web>
</module>
</application>

Client running problem?

Hi guys,
I deployed Session ejb successfully in weblogic server 8.1. i am using standalone server,i included weblogic.jar and client.jar in CLASSPATH.but running client it throws this exception.plz tell me syntax for running client in CMD prompt and also tell me CLASSPATH Setting for Session ejb.
[java] java.lang.NoClassDefFoundError: examples/ejb20/basic/statelessSessio
n/Client
[java] Exception in thread "main"
bye
Priya.M

Hi ,
Before running the ejb client we need to follow the steps as given below.
1)set the weblogic environment using the setWLSEnv
2)set the classpath for ejb(home,remote and bean).
3)run the client program
Note:To set the classpath for the ejb(suppose if we placed the ejb's in ejb folder)
set classpath=d:\ejb;.; %classpath%

Cmp deployment

Hello,
I am using eclipse and ant for development, and do not want to use the studio.
Are there command line tools to generate the sun-cmp-mappings.xml, sun-ejb-jar.xml files? I did find the capture-schema tool to generate the *.dbschema files.
Thanks.
Peter

If anyone interested....
I have found a way to use the capture-schema tool in an ant task.
 <target name="_function.capture_schema">
 <echo message="capturing database to schema file [because sunOne cant do it for us yet.]"/>
 <java classname="com.sun.jdo.api.persistence.mapping.ejb.CaptureSchema">
 <classpath>
 <fileset dir="${j2ee.home}/lib">
 <include name="*.jar"/>
 </fileset>
 <fileset dir="../lib">
 <include name="*.jar"/>
 </fileset>
 </classpath>
 <arg line="-username ${db.user}"/>
 <arg line="-password ${db.pwd}"/>
 <arg line="-dburl ${db.url}"/>
 <arg line="-driver ${db.driver}"/>
 <arg line="-out meta-inf/${db.schema}"/>
 <jvmarg line="-Xms24m"/>
 <jvmarg line="-Xmx96m"/>
 </java>
 <echo message="finisched."/>
 </target>
This way (if you can rely on the capture schema class) you schouldnt have any problems with deploying.
Dont forget to specify the db.schema in the sun-cmp-mappings.xml

Calling a newly deployed EJB from an EJB gives a NoSuchMethod Exception if the jar of the newly deployed ejb is not in the classpath

Hi ,
I have an EJB A which is already deployed when the server starts. A second ejb
B is deployed at a later time.
EJB A calls methods in EJB B. I use reflection in EJB A to call methods in EJB
B.
I get a NoSuchMethodException when I call the create method in the Home object
of EJB B. If I add the ejb jar file to the classpath before the server starts
then it is able to resolve the method.
The problem is the EJBs which are called from EJB A is not known before the server
is started. New EJBs can be deployed at runtime and EJB A should be able call
the methods in newly deployed EJB's.
I also use the URLClassLoader to load all the classes in the jar file of the newly
deployed EJB in EJB A and it still gives a NoSuchMethodException because it cannot
resolve the stub class.
My error log is shown below.
This is an urgent issue.
Thanks

Hi,
I am attaching a test case. This test case actually demonstrates a security bug.
Unzip the file and modify the StartWeblogic.cmd in domainA to not refer to the
SampleRemoteEJB.jar in the classpath. If u run the test client under the client
dir u will see a NoSuchMethodException.
The reason is it is not able to load the dynamically generated stub file.
Initially I had the getMethod and it didn't work. You might have to modify the
files to suit ur env. The easier way is to run th edomain wizard and create 2
domains. Run the servers in development mode and place the jars under the applications
dir
Thanks

Hmmmm. That's an interesting problem.
Why is it giving you a NoSuchMethodException instead of a
ClassNotFoundException?
Can you post the code from SampleConctorEJB.java, line 181?
Try changing your call to getDeclaredMethod() to getMethod().
getDeclaredMethod() searches only the class you called it on, whereas
getMethod() traverses to the superclasses and interfaces. You onlyneed
getDeclaredMethod() when you're accessing a nonpublic method.
Not sure if this will help, but it's worth a shot.
