Spaces server could not start. Failed to load webapp /wcsdocs.

Hi,

If you have got this weird issue in starting webcenter server

Failed to initialize the application ‘webcenter [Version=11.1.1.4.0]’ due to error weblogic.application.ModuleException: Failed to load webapp: ‘/wcsdocs’.

Caused By: weblogic.management.DeploymentException: Error: Unresolved Webapp Library references for “[email protected][app:webcenter module:/wcsdocs path:/wcsdocs spec-version:2.5 version:11.1.1.4.0]”, defined in weblogic.xml [Extension-Name: SomeLibraryName, exact-match: false]

Solution – You need to delete the reference of this library in weblogic.xml and delete this library.First you can check in
/archives/applications and see if there is reference in weblogic.xml .

You can find weblogic.xml using following command.

find / -iname weblogic.xml

If you cant find then check in
/user_projects/domains/DomainName/servers/WC_Spaces/tmp/_WL_user/webcenter_11.1.1.4.0/extend.spaces.webapp

Check weblogic.xml and delete the reference.

Thats it. Happy coding with vinay in techartifact.

Deploy ADF application as shared library in weblogic

Shared library – WebLogic Shared Library is an Enterprise Application Archive, a stand-alone EJB, a Web Application module, or a JAR file that is registered with Oracle WebLogic Server as a shared library. The library resources can be shared between multiple applications, alleviating the need to have duplicate copies of the resources in each application. For an example, we can all dependency as shared libraries in weblogic.

Normally in bigger application, best practice is to use common features application or dependency as shared library in weblogic. For example, taking an webcenter portal application
we are making custom taskflow and using it in webcenter portal application. We can deploy these adf taskflow as shared libraries and can reference in weblogic.xml for Portal application.

We have two option.
– Deploy adf app as jar and then deploy as shared library or wrap jar into war profile and deploy as shared library.
– We can directly deploy adf application as war shared lib in Weblogic.

Following is the process for ADF/ Webcenter Application in jdeveloper

1) Create deployment profile as war file.
2) Create an MANIFEST.MF file as META-INF/MANIFEST.MF

Manifest-Version: 1.0
Implementation-Title: ADF_Shared_Lib
Implementation-Version: 1.0
Specification-Title: ADF_Shared_Lib
Specification-Version: 1.0
Extension-Name: ADF_Shared_Lib

3) Edit war deployment profile and add MANIFEST.MF in war options.

555

4) Deploy ADF taskflow to weblogic(assuming you have made connection with weblogic in jdeveloper) to specific managed server or admin server.
5) mark option as deploy as shared library instead of application.

444

6) In master (Portal) application enter reference of your shared library as follows

ADF_Shared_Lib 1.0
1.0
true

This way you can directly deploy from the jdeveloper. Other options is to deploy as war file and find war file from specified location and go to weblogic admin console
and install as shared library

11111

Note: If you deploying shared library again, make sure, you increase implementation version every time to specify version no.

Video –

Troubleshoot :

IOException: ‘Invalid header field; with manifest
Solution – Make sure name is name is correct. There is proper spacing after colon in manifest file content.

Unresolved WebApp library references defined in weblogic.xml
Solution- Make sure you have same implementation version and specification version of shared library, If there is mismatch you will get this error.

Till then happy deployment in Weblogic with Vinay…..

Enable debugging in remote weblogic for ADF and Webcenter Applications

Hi All,

In my previous post of Debugging taskflow in webcenter spaces , I mention about setting java option in startManagedWebLogic.sh or startWeblogic.cmd .But you can do same thing in more easier way. I will tell about debug flag of weblogic today.

Best way to enable debug flag in WebLogic Server is to use weblogic console. This is done in:

Environment–>Servers–>>–>Debug
Select the required flags and click on Enable/Disable.

Enable the level of debug you need, e.g.: security, servlet, jdbc.This change does not require weblogic Server Restart.

You need Make sure the severity is set to debug in weblogic console:

Environment > Servers > MyServer > Logging >Advanced > Minimum severity to log: Debug
This change requires server restart.

You can also do by follow way as well-

Setting Up setDomainEnv.cmd
Near the top of your file add the following line to enable debugging.

echo ——————————————————————
echo Setting Debug to true
set debugFlag=true
echo ——————————————————————

Locate the following line locate further down the file and make a note of the port number.You can change the default port number as well.

rem set the port number
if “%DEBUG_PORT%”==”” (
set DEBUG_PORT=8453
)

So , if you are working on ADF and Webcenter application , follow this approach to accomplish this task.You should also make connection from jdeveloper
to remote/standalone weblogic server as well.

Following Debug flags will help you debug different issues in Oracle Weblogic Server :
