Developing Java EE applications with Maven NetBeans and Glassfish
Developing Java EE applications with Maven NetBeans and Glassfish
I have been working with EE 6 stack lately, and I find it quite pleasant and productive. For my own learning purpose, I intend to explore more deeper on some of the major components available on the EE stack.
I have started a java-ee6-examples project in GitHub, and I plan to add my examples and working demo code there, along with some blog posts whenever I can. The project is seperated into sub-modules that a typical EE application would organized: a parent module, a common library jar module and one or more web modules etc. The project is buildable using Maven 3 tool on command line, and you may use any major IDE that supports Maven (I will try out NetBeans for these demos).
I will also be testing my examples application mainly on Glassfish Server. Glassfish Server is an open source EE application server, and its current 4.x release supports EE 7 already (GF 3.x is for EE 6). We should able to run any EE 6 applications on GF 4.x without much problems, so for my learning purpose, I will restrict my examples to use EE 6 for now (you will notice that I have to set EE 6 version as dependency in Maven pom file!)
So if you are interested in these, watch this blog for future updates.
To help you started with EE development, I jot down few useful links here.
Downloads:
JDK 7
NetBeans IDE
Glassfish Application Server
(Oracle also provides convenient package download that includes all 3 above!)

Developing Java EE applications with Maven and WebLogic 12c
Developing Java EE applications with Maven and WebLogic 12c
The WebLogic Server 12c has very nice support for Maven now. The doc for this is kinda hidden though, so here is a direct link http://docs.oracle.com/middleware/1212/core/MAVEN
To summarize the doc, Oracle did not provide a public Maven repository manager hosting for their server artifacts. However they do now provide a tool for you to create and populate your own. You can setup either your local repository (if you are working mostly on your own in a single computer), or you may deploy them into your own internal Maven repository manager such as Archiva or Nexus.
Here I would show how the local repository is done. First step is use a maven plugin provided by WLS to populate the repository. I am using a MacOSX for this demo and my WLS is installed in $HOME/apps/wls12120. If you are on Windows, you may install it under C:/apps/wls12120.
$ cd $HOME/apps/wls12120/oracle_common/plugins/maven/com/oracle/maven/oracle-maven-sync/12.1.2/
$ mvn install:install-file -DpomFile=oracle-maven-sync.12.1.2.pom -Dfile=oracle-maven-sync.12.1.2.jar
$ mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=$HOME/apps/wls12120 -Doracle-maven-sync.testingOnly=false
The artifacts are placed under your local $HOME/.m2/repository/com/oracle. Now you may use Maven to build Java EE application with these WebLogic artifact as dependencies. Not only these are available, the push also populated some additional maven plugins that helps development more easy. For example, you can generate a template project using their archetype plugin.
$ cd $HOME
$ mvn archetype:generate
-DarchetypeGroupId=com.oracle.weblogic.archetype
-DarchetypeArtifactId=basic-webapp
-DarchetypeVersion=12.1.2-0-0
-DgroupId=org.mycompany
-DartifactId=my-basic-webapp-project
-Dversion=1.0-SNAPSHOT
Type Y to confirm to finish. Notice that pom.xml it generated; it is using the "javax:javaee-web-api:6.0:provided" dependency. This is working because we setup the repository earlier. Now you may build it.
$ mvn package
After this build you should have the war file under the target directory. You may manually copy and deploy this into your WebLogic server domain. Or you may continue to configure the maven pom to do this all with maven. Here is how I do it. Edit the my-basic-webapp-project/pom.xml file and replace the weblogic-maven-plugin plugin like this:
<plugin>
<groupId>com.oracle.weblogic</groupId>
<artifactId>weblogic-maven-plugin</artifactId>
<version>12.1.2-0-0</version>
<configuration>
<middlewareHome>${oracleMiddlewareHome}</middlewareHome>
<adminurl>${oracleServerUrl}</adminurl>
<user>${oracleUsername}</user>
<password>${oraclePassword}</password>
<source>${project.build.directory}/${project.build.finalName}.${project.packaging}</source>
<targets>${oracleServerName}</targets>
<verbose>true</verbose>
<name>${project.build.finalName}</name>
</configuration>
</plugin>
With this change, you may deploy the webapp into WebLogic server (well, assuming you already started your "mydomain" with "myserver" server running locally. See my previous blog for instructions)
$ cd my-basic-webapp-project
$ mvn weblogic:deploy -DoracleMiddlewareHome=$HOME/apps/wls12120 -DoracleServerName=myserver -DoracleUsername=admin -DoraclePassword=admin123
After the "BUILD SUCCESS" message, you may visit the http://localhost:7001/basicWebapp URL.
Revisit the WLS doc again and you will find that they also provide other project templates (Maven calls these archetypes) for building EJB, MDB, or WebService projects. These should help you get your EE projects started quickly.
