| <h1 id="weblogic">WebLogic</h1> |
| |
| <p>When deploying to WebLogic, some developers report problems with the framework locating resources, especially with Velocity. |
| For more about WebLogic and Velocity, see the <a href="http://wiki.apache.org/jakarta-velocity/VelocityAndWeblogic">Velocity website</a>.</p> |
| |
| <p>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 <code class="language-plaintext highlighter-rouge"><bea_home>/user_projects/domains/mydomain/</code>.</p> |
| |
| <h2 id="adding-a-struts-velocityproperties-configuration-file">Adding a struts-velocity.properties Configuration File</h2> |
| |
| <p>In the <code class="language-plaintext highlighter-rouge">struts.properties</code> file (usually kept in the <code class="language-plaintext highlighter-rouge">WEB-INF/classes</code> directory), add an entry that specifies |
| a Velocity configuration file.</p> |
| |
| <p><strong>struts.properties</strong></p> |
| |
| <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>struts.velocity.configfile = struts-velocity.properties |
| </code></pre></div></div> |
| |
| <ul> |
| <li>Create the corresponding Velocity properties file (“struts-velocity.properties”), preferably in the same location |
| as the <code class="language-plaintext highlighter-rouge">struts.properties</code> file.</li> |
| <li>Copy into the Velocity properties file the contents of the <code class="language-plaintext highlighter-rouge">velocity.properties</code> file that is the the SAF <code class="language-plaintext highlighter-rouge">velocity-dep.jar</code>.</li> |
| <li>In your new <code class="language-plaintext highlighter-rouge">struts-velocity.properties</code> file, find he section titled <code class="language-plaintext highlighter-rouge">T E M P L A T E L O A D E R S</code>, and change this section as so:</li> |
| </ul> |
| |
| <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code> |
| =========================================== |
| resource.loader = class |
| |
| file.resource.loader.description = Velocity File Resource Loader |
| file.resource.loader.class = org.apache.velocity.runtime.resource.loader.FileResourceLoader |
| file.resource.loader.path = . |
| file.resource.loader.cache = false |
| file.resource.loader.modificationCheckInterval = 2 |
| |
| class.resource.loader.class = org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader |
| class.resource.loader.cache = true |
| =========================================== |
| |
| </code></pre></div></div> |
| |
| <ul> |
| <li>Redeploy a fresh WAR to WebLogic.</li> |
| </ul> |
| |
| <h2 id="npe-when-using-struts-2-jasper-reports-plugin">NPE when using Struts 2 Jasper Reports plugin</h2> |
| |
| <p>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).</p> |
| |
| <h2 id="convention-based-application-doesnt-work">Convention based application doesn’t work</h2> |
| |
| <p>When you deployed an application that base on the Convention Plugin and you get an error messages that says:</p> |
| |
| <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>There is no Action mapped for namespace / and action name xxxxxx |
| </code></pre></div></div> |
| |
| <p>create struts.properties file in WEB-INF/classes folder (in the expanded application’s folder or in the source code) with below statements:</p> |
| |
| <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#struts convention property modifications for Weblogic |
| struts.convention.action.includeJars=.*?/yourwebapp.*?jar(!/)? |
| struts.convention.action.fileProtocols=jar,zip |
| </code></pre></div></div> |
| |
| <p>Thanks to Amit who the first published solution on his <a href="http://tech-architecture.blogspot.com/2009/02/getting-struts-21-to-work-in-weblogic\">blog</a>.</p> |
