Eclipse Maven Weblogic hot code swap

Question

I have a basic question about running a Java EE application on Weblogic using maven in eclipse.

I use OEPE (Oracle Enterprise pack for Eclipse) which comes with some plu

Answer 1

Let me provide you with my checklist to make my web application hot-deployed on Weblogic. This checklist assumes a weblogic version which implements Servlet 2.5 and assumes your project is a maven one which is configured to run maven-compiler-plugin for JDK 1.6. In other words your weblogic version is 10.x.x and your POM includes the following snippet:

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
    <source>1.6</source>
    <target>1.6</target>
</configuration>

To build a war

Use OEPE plugin to create a new Weblogic Web module Weblogic.xml file:

• Don’t enable spring extension
• In FastSwap: Don’t enable class redefinition

• Take note of the value

  <wls:context-root>myappcontextroot</wls:context-root> 
  

  it will be used later in the hot-deployment

Execute Maven update project from Eclipse context menu of your project

Execute Maven clean install

For hot-deployment setup:

• Add local weblogic as a runtime server in Windows->preferences->Server->Runtime. Remember to change its Java home to the Sun JDK instead of JRocket for development mode.
• Add local server in Server->add server
• Project context menu->properties->Project Facet-> add faceted nature
• Make Sure Jave Facet is version 1.6
• Check Dynamic web application version 2.5 and make the target runtime be the runtime server declared in the first step + In further configuration give “context root” the value "myappcontextroot" which was noted above and give “Content directory" the value "src\main\webapp”. Don't generate web.xml otherwise your web.xml is overwritten
• Push OK to apply all the above facet changes to your project
• Again open Project context menu->properties->Deployment Assembly->Add java build path->Maven dependencies
• Finally, in the server window Add configured application to the running server

Please follow these steps literally, it is really worth it!
