Hot Deplyment in Weblogic-10.3?

Hi All,
This is Prem..Can anyone let me know whether the Hot Deployment process is possible in Weblogic-10.3? I have copied the deployment folder directly to the following location (without creating a WAR) C:\bea\user_projects\domains\my_domains\autodeploy folder?
It is giving the Error...
Failed to create the instance of web Appl : Jndi (It is the name of my deployment folder)
Awaiting for your early response
Thanks in Advance
Prem Alapati

Hi Prem,
Can u please paste the complete StackTrace of the exception which u are getting?
Are u running your Server in Production Mode or in Development Mode?
Is your Application working fine when u are deploying your application with some other options like: Console Deployment or WLDeployer Deployment?
Thanks

Hot deploy in weblogic 10.0 not working

Hi,
I am trying to do hot deploy in an exploded war deployment. If I deploy the same exploded war in weblogic 9.2, I can update the class files without restarting the sever. However, in weblogic 10.0 system throws “java.lang.ClassCastException: com.xxx.xxx.xxxxx” when it tries to reload the app after the old class file has been updated with a new one. If the server is restarted then the new class file is picked without any errors. Are there different settings in weblogic 10.0 to enable hot deploy? Please let me know.
Thanks a lot.

Please don't cross-post.

Did anybody get hot deploy in an expanded directory format to work
in weblogic 6.0 sp2. I have tried to follow the documentation but
couldn't get it to work.

Hot deployment in weblogic

Hi
I have some questions related to hot deployment.
1. Is Hot Deployment similar to auto-deploy option in development mode?
2. Using Auto-deploy is it possible to get the application deployed on managed server
( I found that it gets deployed on Admin server and it is not recommended to deploy on Managed.. but is there any way to deploy on managed server)
3. my application (ear) has dependencies... those are deployed as library.. is it possible to deploy library using auto-deploy
Thanks

1. no - hot deployment, deploy, redeploy, or undeploy an application while the server is running without affecting other applications or requiring a server restart
2. no - the admin server has a feature known as auto-deployment that is enabled when you create a domain using development mode. With this feature, the server watches the autodeploy directory for changes and automatically deploys new or changed applications that it finds there.
3. why would you want that - just deploy the libraries and refer to those libraries in your deployment overrides.
Better way to auto-deploy is using the wldeploy Ant task. (http://download.oracle.com/docs/cd/E11035_01/wls100/programming/wldeploy.html)

Hot deployment problems with weblogic 7.0 sp2

Hi Guys
I am trying out hot deplyment of a j2ee application on WebLogic Server 7.0 SP2
Approach 1
The application is deployed in exploded ear format from the folder
d:/work/testbed/ear. The appropriate entry in config.xml looks like this.
<Application Deployed="true" Name="Testbed"
Path="D:\tools\bea702\projects\testbed\applications\testbed"
StagedTargets="" TwoPhase="false">
<EJBComponent Name="SessionBeans" Targets="myserver" URI="SessionBeans.jar"/>
</Application>
Creating or touching the REDEPLOY file in META-INF folder doesnt cause hot
deployment to occur
Approach 2
Copied the ear file to the applications folder. Creating or touching the
REDEPLOY file in META-INF file caused the application to be redeployed.
However the weblogic console is constantly spitting out this message.

It seems that the application is getting undeployed and reactivated every 5
seconds.
Questions
1) Any reasons why approach 1 didnt work
2) What could be causing this constant undeployment and reactivation
Thanks for your time
anand

I think I figured out what is causing the application to be redployed every 5
seconds. It seems that if the application is deployed in the weblogic domains
applications folder you should NOT create a <Application element. Weblogic
automatically recognizes all applications in this folder and deploys them.
Removing the application entry (as shown in Approach 1) from the config.xml
and hot deploying by touching the REDEPLOY file did the trick.
One question still remains. Is hot deployment only possible when I copy the
exploded ear to the domain "applications" folder
Thanks for your time
anand
ps : The idea of trying it without the <Application element came from trying
out hot deployment in Weblogic 8. WLS8 first deploys the application in the
applications folder, followed by the application configured in the
<Application element. Since both the applications were essentially the same it
gave me a JNDIException saying that some entity is already bound with the same
name. Weblogic 7 however doesnt complain at this point.

Hot deploy, classloading & singletons

I have the following doubt about hot-deploy, classloading & singletons.
Let´s assume I have a sessionbean which accesses a singleton. As far as I understand
hot-deploy in weblogic, during a hot-deployment, a sessionbean instance currently
engaged in a transaction is not unloaded untill the transaction is completed.
New transactions however would access the newly deployed & loaded instances of
the new version of my session bean.
Am I correct to assume that, if this is the case, several instances of my singleton
may exist at a certain moment in the same JVM (I am not talking about clusters,
but about execution threads).

Hi Seth
Are you hot redeploying the entire application? Is the singleton class
packaged with the application?Yes the singleton is packaged with the application. It´s actually the Bussiness
Delegate.

Thanks.

Hot swap and JSP debugging for Weblogic in exploded format?

Hi,
I'm trying to use JDeveloper for JSF development to be deployed to a weblogic server.
I must say JDeveloper is a great tool for JSF development as none of the free IDE in the market can do what JDeveloper does.
However, I have a question on hot swap and JSP debugging.
I have managed to setup JDeveloper to debug my JSF application deploy to my Weblogic server's applications folder in exploded format.
I can step through the java code.
However, I didn't manage to do a hot swap and the break point set in the JSF-JSP does not seems to take effect.
I would appreciate any advice on the problem.
Thanks.
Han Ming

How did you setup the server to handle exploded format? Appreciate the help. Sorry can't help with your question though.
Thnx.

Exploded (hot) deployment on a Weblogic cluster

AFAIK, exploded hot deployment on a Weblogic cluster is not supported through OEPE.
When deploying an application on a cluster, each change, no matter how small, forces you to republish these changes, ultimately causing the application to be redeployed by OEPE. Turnaround time for this (depending on the app) can take some time.
Is there a workaround available for this ?
I'm looking for a way to minimize the turnaround time between developing code, and actual seeing the code changes on the screen. The requirement however is that deployments should be possible on a managed instance / cluster (non AdminServer).
Does Oracle Weblogic support such "hot deployment" capabilities from an IDE like Eclipse ? Does anybody here have such a process in place ? (perhaps using ant / maven2 tooling)

Hi
I want to clarify that the application has to be deployed to a cluster of two managed servers, amandad_Server_1 (On Windows server hosting console) and amandad_Server_2 which is running in other Windows server.
I deployed the application following your recdommendations and the resulta is as follows:
Windows server (running the console)
1 EAR file was copied to ... \user_projects\domains\amanda_domain\servers\amandad_Server_1\stage
2. The application files extractected from the EAR files were copied to   \user_projects\domains\amanda_domain\servers\amandad_Server_1\tmp
Windows Server not runn ing the console
No files were copied to neither
... \user_projects\domains\amanda_domain\servers\amandad_Server_2\stage
     \user_projects\domains\amanda_domain\servers\amandad_Server_2\tmp
Questions
1 Windows server not running the console the files were not copied....What might cause this behaviour....? how to fixi it...?
2. Do I have to manaully copy the files to folders
...\user_projects\domains\amanda_domain\servers\amandad_Server_2\stage
   ... \user_projects\domains\amanda_domain\servers\amandad_Server_2\tmp

Weblogic hot deployment

Hi all,
Does any body know how to redeploy a web application in weblogic without restarting the server?
I have my application in the exploded file format...
Thanks in anticipation,
Seshu

HI,
Thank u for the prompt reply. I am using weblogic 8.1 and i want to know whether there is any Hot Deployment feature in 8.1.
I've gone thru the weblogic 7.0 documentation. It says that the server automatically reloads all the files every x secs. which we can specify in the console.
but doing so doesn;t reflect my changes......
is there any other way? (i've tried touching the REDEPLOY file too)..
Thanks,
Seshu

Eclipse Maven Weblogic hot code swap

I have a basic question about running a JEE application on Weblogic using maven in eclipse. I use OEPE (Oracle Enterprise pack for Eclipse) that we know comes with some plugins such as m2e and wtp. As far as I know this plugins read the pom file and based on them build the jar, war and ear files. What I do right now is like this: I check the build automatically option and let these plugins create my EAR file, then right click on the instance of weblogic server in Eclipse and add it to server using add/remove option and finally start the application server. This way when I change code in my classes they will be picked by application server and hot swap works. Another way to build the EAR file is using the m2e plugin: right click on the parent pom file and choose maven install then start the application server and use the wls:deploy in order to deploy the EAR file. (This time I don't add the ear file to the application server from within the Eclipse and eclipse also is not aware of that EAR file when I right click on the instance of my weblogic inside the IDE). As far as I've seen I can only add those artifacts to server which are built using the wtp plugin and not the artifacts that are built using maven command of m2e plugin. The problem with wtp and all these plugins (except for m2e which actually just runs mvn -install) is that they don't work flawlessly. Sometimes they don't build the artifacts correctly sometimes the jar files are obsolete and they don't get updated. Moreover when you use the jar file of one project in another maven project they get stuck with the jar file prior to your changes, while using the m2e they are built flawlessly. Now here is the real question: Which way is the correct one to have hot deploy? Am I missing something? Is building the ear file using m2e plugin and deploying using wls:deploy enough? If so how will hot swap happen by itself or should i use wls:redeploy each time? If m2e is enough then I assume that I should abandon wtp plugin (it does not know all the plugins of pom file and I should sometimes mark them as ignored in lifecycle management xml file of eclipse).
I'm sorry that the question is that long but I hope that I made the case clear and get some help!
Cheers.

I assume that by maven integration in eclipse you specifically mean the m2e plugin. Then what about wtp plugin? And by not using maven and managing the dependencies in eclipse: Do you really mean that I, myself should care about putting my jar files war file in my ear file and going back to the old fashioned library management? (If this is the case then it isn't worth it because working without maven is just wasting time and out of industry standards nowadays.) Or maybe I've not understood this sentence exactly :
but you will need to manage your projects dependencies in Eclipse, not via pom files.

How to hot deploy EJB in Weblogic?

Hi all,
We use Weblogic 10.3 and EJB3.
EJB has been build as ear and deployed in the server. And other deployed modules in server calls that.
But the modification of EJB need to be rebuilt and restart the server.
Does Weblogic support hot deploy for EJB? Do we need plugin or something else for this feature?
Thanks a lot.

Hi,
The production redeployment strategy/hot deployment is supported for:
a. Standalone Web Application (WAR) modules and Enterprise applications (EARs) whose clients access the application via a Web application (HTTP).
b. Enterprise applications that are accessed by inbound JMS messages from a global JMS destination, or from inbound JCA requests.
c. All types of Web Services, including conversational and reliable Web Services, but not 8.x Web Services.
Production redeployment is not supported for:
a. Standalone EJB or RAR modules. If you attempt to use production redeployment with such modules, WebLogic Server rejects the redeployment request. To redeploy such modules, remove their version identifiers and explicitly redeploy the modules.
b. Applications that use JTS drivers. For more information on JDBC application module limitations, see JDBC Application Module Limitations in Configuring and Managing JDBC for Oracle WebLogic Server.
c. Applications that obtain JDBC data sources via the DriverManager API; in order to use production redeployment, an application must instead use JNDI to look up data sources.
d. Applications that include EJB 1.1 container-managed persistence (CMP) EJBs. To use production redeployment with applications that include CMP EJBs, use EJB 2.x CMP instead of EJB 1.1 CMP.
Please check the below Doc
http://docs.oracle.com/cd/E14571_01/web.1111/e13702/redeploy.htm#
Hope this answers your question!!

When we registered our jar in the weblogic.properties file - everything is OK.
This ejb cotains correct EJB's which are made in EJB 1.1 standard.
In the WebLogic EJB DeployerTool I attach proper WeaWeblogic application server
(it works on another computer, but tool found our server confidently. Then I opened
my jar file. Tool parsed file and found all beans.
After all I'm trying to run Tools/Deploy and I have the error message showed below.

Is SP11 jars in the client classpath or not, before launching DeployerTool.
If yes, then it looks like a bug. You might want to report this problem to

How to debug web app with weblogic?

I wrote a web app that includes jsp files and some javabeans, then I put the jsp files to directory
mydomain\applications\DefaultWebApp
then I complied javabeans and put those classes to
mydomain\applications\DefaultWebApp\WEB-INF\classes
Then I start the weblogic,it runs very well.
I modified some javabean, complie them and put classes override the old classes,
but the web app can not find the new classes.
Any one know How to debug web app(with javabeans) in weblogic?
thanks!

how to config the hot deploy?
thxSorry, for this delay in responding. I had set notify me with email option in Watch This topic; but I never did get any email notification.
I use wls6.1; I think the process may be very similar to this in wls8.x. In wls6.1 (sp5), this is done via the -
Dweblogic.ProductionModeEnabled=False or
Dweblogic.ProductionModeEnabled=True
in the startup cmd/sh script. Out of the box, wls6.1 is set to Dweblogic.ProductionModeEnabled=False which automatically enables hot deploys.

HOT Redeployment of EAR fails with Classloader error

App Server: WLS 10.3
OS: Solaris 9
I have installed WLS installed with a domain, admin and a managed server. Everything is working fine.
I have WAR and EAR deployed successfully on the Managed Server.
HOT deployment of WAR files works perfectly fine.
There is this EAR "IIA.ear" with @ 8 WAR files and 1 jar "Manager.jar". The EAR has been deployed in the "nostage" mode.
I do not have any separate "Deployment" plan.
In order to "redeploy" the EAR I go to the Admin console >> Deployments >> Select the EAR >> update >> Source Path remains the same >> Finish
I get the following error :
+#####################+
weblogic.application.CannotRedeployException: Module 'Manager.jar' has the same ClassLoader as the Application 'IIA'. Consider redeploying the entire application.

does WLS 10 supports HOT deployment of EAR files? Is it any issue with "Class Loading"? Anything to be changed to make this HOT redeployment successful?

App Server: WLS 10.3
OS: Solaris 9
I have installed WLS installed with a domain, admin and a managed server. Everything is working fine.
I have WAR and EAR deployed successfully on the Managed Server.
HOT deployment of WAR files works perfectly fine.
There is this EAR "IIA.ear" with @ 8 WAR files and 1 jar "Manager.jar". The EAR has been deployed in the "nostage" mode.
I do not have any separate "Deployment" plan.
In order to "redeploy" the EAR I go to the Admin console >> Deployments >> Select the EAR >> update >> Source Path remains the same >> Finish
I get the following error :

weblogic.application.CannotRedeployException: Module 'Manager.jar' has the same ClassLoader as the Application 'IIA'. Consider redeploying the entire application.
Update operation failed - no deployments changed.

Weblogic portal 9.2/10 scheduling (urgent)

Hi,
Could someone explain or point me to the correct resources on the net for information on the following questions please?
Publishing/scheduling - Creating a portal in workshop and deploying it to the server is called the development mode. Creating a view (desktop) for this portal in the administration console and viewing this on the browser is the staging mode?
What exactly is the production mode? How is this staged application moved into production the first time and later after any changes have been made to the portal?
Is it possible to schedule a publish/deplyment from staging to production? Does the administration console support this?
Thanks

What i understand is that production mode is applicable to Weblogic server.
The desktop and other view need to be either created on production server (bad choice) or they have to be created in the staging environment and moved to production environment with the help of propagation tool.
Check out this link http://e-docs.bea.com/wlp/docs100/prodOps/propToolAdvanced.html
Thanks
