EJBs in weblogic8.1
Hi,
I don't whether i am shooting the problem at right place or not.
I created a ejb in weblogic8.1 workshop. It created a filename with .ejb extension. I want to access this ejb from the java client. I don't know how to access it sinceim not able to see the local or remote interfaces to extract. How abuild it using the ant script.
Typically you just update the class and then redeploy the application.
If you used BuildXMLGen to generate your build.xml, there will be a redeploy target pre-created for you.

How to run EJB IN WEBLOGIC8.1?
Hi
Can any one tell me how to run Ejb in Weblogic8.1?
Thanksbikash2007 wrote:
how to run ejb using WEBLOGIC8.1?you noticed, of course, that the original request was 3 years old.
same as any other java ee app server, of course - package your ejbs in an ear and deploy it to the /application directory once you've created a user domain for that project. consult the bea docs for the details, but that should be enough to get you started.

Is there ejb TimerService in Weblogic8.1 server?
Hi,
In J2ee1.4, there is a TimerService in "javax.ejb" folder. The TimerService interface
provides enterprise bean components with access to the container-provided Timer
Service. The EJB Timer Service allows entity beans, stateless session beans, and
message-driven beans to be registered for timer callback events at a specified
time, after a specified elapsed time, or after a specified interval.
I wonder if there is a similar mechanism available in Weblogic8.1 server now to
let us achieve
Timer operations for ejbs.
Thanks,
Clark WangWeblogic 8.1 supports only J2EE1.3, since J2EE1.4 is not yet finalized.
However there may be a timer service or a scheduled messaging service in the
server,
but that would be Weblogic-specific.

Deployment in Weblogic8.1 Falied due to EJB-QL
Hi,
While depolying the application on Weblogic 8.1 Sp2, am getting WARNING(S) from EJB QL Compiler.
for instance :
[EJB:011017]Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was:
Query:
EJB Name: EOTransactionBean
Method Name: findByEoNum
Parameter Types: (java.lang.String)
SELECT o FROM EOTransactionBean o WHERE =>> eoNum <<= = ?1
EJB QL compilation encountered error: [EJB:013080]
Problem, the path expression/Identifier 'eoNum' starts with an identifier: 'eoNum'. The identifier 'eoNum', which can be either a range variable identifier or a collection member identifier, is required to be declared in the FROM clause of its query or in the FROM clause of a parent query. 'eoNum' is not defined in the FROM clause of either its query or in any parent query.
Action, rewrite the query paying attention to the usage of 'eoNum'.
==========================================================
How can I overcome this? Is there a workaround for this? I read that there is a temporary patch available for this. If so please help. Thanks.
Regards,
Davidyou can try with this query
select object(o) from EOTransancationBean As o where o.eoNum >= or <= ?1 -

sasiIt's hard to know exactly, just given this.
is this a regression from a previous release (I suspect not).
As an experiment, would be be possible to try replacing the BETWEEN
expressions with something like ?n > lower_value AND ?n < upper_value
and seeing if this makes a difference ? -

This is very surprising error I am getting. Because getHandle(), getEJBHome(), isIdentical() are no where declared in business interface extending EJBObject.

Error while migrating JMS application from Weblogic8.1 to Weblogic10.3
Hi All,
I am migrating my JMS application from weblogic8.1 to 10.3. I'm able to publish and subscribe message from local weblogic server. But when i'm configuring ldap server in weblogic-ejb-jar.xml, while deploying the application itself i'm getting the below error. Same thing working fine in weblogic8.1.
For this am i need to use foreignjms?. If this is the case please let me know how to configure foreignjms in weblogic10.3 server.

[email protected] on Mar 18, 2009 3:07 AMHello TomB,
Could you elaborate a bit on your explanation? I'm having the same problem as talk2srujan. I currently have an application which works fine in weblogic81 and, when migrated to weblogic103, fails at deployment time. The error I get is: unable to find EndPointFinder for tibjmsnaming://host:port
We didn't have to register any foreign servers in weblogic81, should I do this in weblogic103?
Could you also give a pointer to the known bug you mentioned?
Thanks in advance,

A problem determining the JNDI Name of a local EJB with WL 8.1
Hi,
I created a very simple local EJB and deployed it with Weblogic8.1. When I test
it in the Weblogic server admin page, I got the following message:
"The EJB MyLocal has not been tested successfully. There was a problem determining
the JNDI Name of the given bean."
Can anyone help figure out the problem?
Thanks
HenryDoes the ejb have a target server specified?
Does the Ejb have a Jndi binding as specified in the <local-jndi-name></local-jndi-name>
element of weblogic-ejb-jar.xml?
thanks,
Deepak

How to deploy and run EJB in eclipse without XDoclet
Hi Friends
I am new in j2ee.In my academic project i want to do some ejb programming.
For that purpose i want to write some ejb's.I have written all required class for ejb,created ejb-jar.xml file manually,weblogic .xml file manually. I am using weblogic8 as an server for deployment.
I know deployment with xdoclet but i want to know hoe to deploy ejb without xdoclet.
If u have saple code or useful link regarding this please send it as soon as possible.
Thanks in advance
How to deploy and run EJB in eclipse without XDocletHI Welcome to J2ee...
I am also new to this...But i ll share my ideas with you...
In EJB 3.0 No need of any Deployment Descriptors....
And If you are using Eclipse You can Deploy(as jar) using Export in File tab...
XDoclet is not mandatory...

Startup class/process for EJB application
Hi,
I have an EJB module deployed on WebLogic8.1. My requirement is I would like to have a startup/shutdown class which is called when the EJB application is deployed. I have made some research and have found I can write startup/shutdown classes when for the server life cycle or for application life cycle events. Can anyone tell me write/deploy a startup/shutdown class for the EJB module life cycle.
Thanks,
FaizullaHi,
For Server life cycle events you can write server startup/shutdown classes.(You can see it from the console application)
For application life cyccle events, please go through:
http://e-docs.bea.com/wls/docs81/programming/app_xml.html#1007582
You can specify it <listener> part of application.xml.
This is impossible in J2EE standard. But perhaps this can be achieved by some app. server specific extensionYes,in earlier versiobns there was weblogic-ejb-extensions.xml file in which you can specify startup/shutdown class, like:
<!DOCTYPE weblogic-ejb-extensions SYSTEM "weblogic-ejb-extensions.dtd" >
<weblogic-ejb-extensions>
<module-initializer-classs>
<moduleinitializer-class-name>com.dcons.iss.ejb.MUTBStatusObject</moduleinitializer-class-name>
</module-initializer-class>
</weblogic-ejb-extensions>
But it's no longer in use.
I am still findind out a way for my EJB module initializer class.
Regards,
Faizulla -
Weblogic 8.1 and EJB packaging with appc
We are deploying each EJB as a seperate JAR file with individual ejb-jar and weblogic-ejb-jar.xml files. This is under Weblogic 7.1. In our build script we are using <ejbjar> with nested <weblogic> element for packaging.
We are planning to migrate to Weblogic8.1 and it was recommended to use appc instead of ejbc. What is the best way to prepare ejb jar file using <ejbjar> task and not using <weblogic> element. How do we prepare the the individual jar files without having to have individual <ejbjar> task for each EJB?54275,
any suggestions to resolve this will be greatly
appreciatedI would like to make a suggestion: Investigate the object returned from your stored procedure via Java's reflection mechanism.
By the way, if you're calling a stored procedure, shouldn't you be invoking the "execute()" method (of "java.sql.CallableStatement") and not the "executeUpdate()" method?
Good Luck,
