GWT, Maven, Eclipse and WebLogic: take 2

Maven + GWT
I needed to create a GWT project using maven again. The original post lacked some details. This time, I got it to work with a slightly different steps. First, I ran the following command:

mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo -DarchtypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.4.0

Somehow, Maven didn’t pickup the group ID and artifact ID. So, I had to choose from one of the listed item.

Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): : 337
Choose org.codehaus.mojo:gwt-maven-plugin version: 
1: 1.1
2: 1.2
3: 2.1.0
4: 2.1.0-1
5: 2.4.0
Choose a number: 5: 5

Next, I defined the properties for my project.

Define value for property 'groupId': :
Define value for property 'artifactId': : directoryNameForTheGeneratedProject
Define value for property 'version':  1.0-SNAPSHOT: :
Define value for property 'package':
Define value for property 'module': : moduleName

Now I can run the generated module with the following command. This will bring up a console. All I have to do is copy the URL and then past it in the browser.

mvn gwt:run

Maven + Eclipse
Next, I followed the instructions on this page to run the following command within the project folder to enable support for Eclipse:

mvn eclipse:eclipse

Then, I use Eclipse to import existing project into workspace to open the project. Eclipse complained that the default directory for the project should be set to /PorjectFolder/src/main/webapp/WEB-INF/classes Since I want to use Maven to build, I ignore the error by right click on the error, choose quick fix, choose Do not use the WAR directory for ProjectName launching and deploying (this disables management of WEB-INF)

Maven + WebLogic
I noticed that the JRE libraries were referencing version Java SE 7 jars, I changed it to 6 so the project will be compatible with WebLogic 11g. For WebLogic 12c, see this post.

I followed the instructions to configure WebLogic 11g with Maven. The available commands for 11g are slightly different from 12c. They are are deploy, help, list-apps, redeploy, start-app, stop-app, undeploy, update-app. Once I completed the configuration, I was able to run mvn weblogic:list-apps command. Next, I ran mvn package to create the WAR file before attempted mvn weblogic:deploy. I was able to load the application in my browser! 🙂
