When deploying to WebLogic, some developers report problems with the framework locating resources, especially with Velocity. For more about WebLogic and Velocity, see the Velocity website. |
| Info |

To deploy to WebLogic, the common approach is to create and deploy an unexpanded WAR to the WebLogic deployment directory. With WL 8.x, the deployment directory is typically at |
Adding an struts-velocity.properties Configuration File
...
- In the
struts.propertiesfile (usually kept in the
WEB-INF/classesdirectory)
...
- , add an entry that specifies a Velocity configuation file.
Code Block title struts.properties struts.velocity.configfile =
...
struts-velocity.properties
...
- Create the corresponding Velocity properties file ("struts-velocity.properties"
...
- ), preferably in the same location as the
struts.propertiesfile.
- Copy into the Velocity properties file the contents of the
velocity.propertiesfile that is
...
- the the SAF
velocity-dep.jar
...
- .
- In your new
...
struts-velocity.properties
...
- file, find
...
- he section titled
...
- "
T E M P L A T E L O A D E R S", and change this section
...
- as so:

- Redeploy a fresh WAR to WebLogic.
NPE when using Struts 2 Jasper Reports plugin
When using mentioned plugin in Weblogic 11g you can get NullPointerException within Struts 2. To solve the problem you must enable the "Archived Real Path" global property in Weblogic admin console > configuration > Web Applications. It's because JasperReportsResult determines the report directory base on servletContext.getRealPath(finalLocation).
Convention based application doesn't work
When you deployed an application that base on the Convention Plugin and you get an error messages that says:
| No Format |
|---|
There is no Action mapped for namespace / and action name xxxxxx
|
create struts.properties file in WEB-INF/classes folder (in the expanded application's folder or in the source code) with below statements:
| No Format |
|---|
#struts convention property modifications for Weblogic
struts.convention.action.includeJars=.*?/yourwebapp.*?jar(!/)?
struts.convention.action.fileProtocols=jar,zip

Thanks to Amit who the first published solution on his blogNote: The "when deploying this way" comment above refers to deploying a war file (not expanded) into the deployment directory of WebLogic; with WL 8.x, this is typically at <bea_home>/user_projects/domains/mydomain/.
