C Using the WebLogic Maven Plug-In for Deployment

Apache Maven is a software tool for building and managing Java-based projects. Now you can use a Maven plug-in for WebLogic Server (weblogic-maven-plugin) to perform deployment operations similar to those supported by the command-line utility, weblogic.Deployer. The plug-in lets you deploy, redeploy, update, and such, applications built using Maven to WebLogic Server from within the Maven environment. The weblogic-maven-plugin works with Maven 2.x and 3.x.

To download and configure Maven on supported platforms, see http://maven.apache.org/download.html. Be sure to read the set up instructions closely to ensure that Maven is working correctly in your environment.

For detailed information on using Maven to build applications and projects, see the Maven Users Centre at http://maven.apache.org/users/index.html.

The following sections describe using the weblogic-maven-plugin for deployment:

Configuring and Using the WebLogic Maven Plug-In

Follow these steps for generating, installing, and using the weblogic-maven-plugin:

Note:

To successfully accomplish these steps, your computer must be connected to the Internet and have the necessary proxy settings configured correctly in the settings.xml file (typically $HOME/.m2/settings.xml). For further details, see http://maven.apache.org/guides/mini/guide-proxies.html.

  1. Build the plug-in JAR file using the WebLogic JarBuilder Tool (wljarbuilder) under MW_HOME/wlserver_10.3/server/lib/ with the following command:

    java -jar wljarbuilder.jar -profile weblogic-maven-plugin

    The weblogic-maven-plugin.jar contains a Project Object Model (pom.xml) file which specifies the groupId, artifactId, version, and packaging of the weblogic-maven-plugin.jar:

    groupId=com.oracle.weblogic
artifactId=weblogic-maven-plugin
version=10.3.6.0
packaging=maven-plugin

    These fields identify the plug-in and mark a specific place in a Maven repository, acting like a coordinate system for Maven projects.

    Note:

    As of WebLogic Server 10.3.5, the plug-in version number has been changed to match the WebLogic Server version number and must include four digits, for example, 10.3.5.0, 10.3.6.0.

  2. Extract the pom.xml file from weblogic-maven-plugin.jar under the MW_HOME/wlserver_10.3/server/lib directory, and then copy the pom.xml file to MW_HOME/wlserver_10.3/server/lib.

    For example:

    jar xvf MW_HOME/wlserver_10.3/server/lib/weblogic-maven-plugin.jar 
META-INF/maven/com.oracle.weblogic/weblogic-maven-plugin/pom.xml

cp MW_HOME/wlserver_10.3/server/lib/META-INF/maven/com.oracle.weblogic/
weblogic-maven-plugin/pom.xml MW_HOME/wlserver_10.3/server/lib

  3. Provision the weblogic-maven-plugin.jar in your local Maven repository with the following command. However, for a shortened command-line goal invocation of the plug-in, follow the directions in step 5 before performing this step.

    mvn install:install-file 
-Dfile=MW_HOME/wlserver_10.3/server/lib/weblogic-maven-plugin.jar -DpomFile=pom.xml

    Typical command output is like the following:

    Note:

    Because the mvn install command downloads Maven dependencies from the Internet which are required for the successful execution of Maven goals, you must have run mvn install at least once on your local machine.

  4. Use the Maven plug-in by employing either of the following methods:

    Note:

    As of WebLogic Server 10.3.6, you can execute weblogic-maven-plugin goals outside of a Maven project. For example, you can use the weblogic:deploy goal as a standalone operation to deploy a WAR file from any directory; the directory need not contain a Maven pom.xml file.

    • From the command line—By invoking a goal from the command line.

      For example, using the goal full name to deploy:

      mvn com.oracle.weblogic:weblogic-maven-plugin:deploy

      Or, optionally, if you've configured using the shortened command-line goal invocation (see Step 5):

      mvn weblogic:deploy

    • From a POM file—By including the Maven plug-in in the application's pom.xml file.

      You add the plug-in into any life cycle phase of the project. Optionally, you can add a goal to any of the default Maven life cycle phases by adding an executions tag in the pom.xml file. The goal is then bound to that particular phase of the Maven life cycle. For example, as shown in Example C-1, the goal is bound to the "install" phase of the Maven life cycle. By doing this, every time you run the mvn install command, the deployment plug-in is also called.

      Example C-1 Maven Project pom.xml File

      <build> 
  <plugins> 
   <plugin> 
      <groupId>com.oracle.weblogic</groupId> 
      <artifactId>weblogic-maven-plugin</artifactId> 
      <version>10.3.6.0</version> 
      <configuration> 
          <adminurl>t3://localhost:7001</adminurl>
          <user>weblogic</user> 
          <password>weblogic123</password> 
          <upload>true</upload> 
          <action>deploy</action> 
          <remote>false</remote> 
          <verbose>true</verbose> 
<source>${project.build.directory}/${project.build.finalName}.${project.packaging}</source> 
         <name>${project.build.finalName}</name> 
      </configuration> 
      <!-- 
      <executions> 
         <execution> 
            <phase>install</phase> 
              <goals> 
                <goal>deploy</goal> 
              </goals> 
         </execution> 
       </executions> 
       --> 
  </plugin> 
    . 
    . 
    . 
 </plugins> 
</build>

  5. Optionally, you can install the plug-in so that you can use it with a shortened name (weblogic) instead of the full name (com.oracle.weblogic:weblogic-maven-plugin), greatly increasing its ease of use. To accomplish this you need to edit the pom.xml file to add the additional <build> stanza, as shown in Example C-2, and execute the mvn install command, before installing the weblogic-maven-plugin.

    1. Modify the settings.xml file located in your $HOME/.m2 directory, as follows:

      <!-- pluginGroups
 | This is a list of additional group identifiers that will be searched 
 | when resolving plugins by their prefix, for example, when invoking a  
 | command line like "mvn prefix:goal". Maven will automatically add the 
 | group identifiers "org.apache.maven.plugins" and "org.codehaus.mojo"
 | if theses are not already contained in the list.
 | -->
<pluginGroups>
   <!-- pluginGroup
      | Specifies a further group identifier to use for plugin lookup.
    -->
   <pluginGroup>com.oracle.weblogic</pluginGroup>
 </pluginGroups>

    2. Edit the MW_HOME/wlserver_10.3/server/lib/pom.xml file, as follows:

      Example C-2 pom.xml File

      <project xmlns="http://maven.apache.org/POM/4.0.0" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.oracle.weblogic</groupId>
  <artifactId>weblogic-maven-plugin</artifactId>
  <packaging>maven-plugin</packaging>
  <version>10.3.6.0</version>
  <name>Maven Mojo Archetype</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-plugin-api</artifactId>
      <version>2.0</version>
    </dependency>
  </dependencies>
 
  <build>
   <plugins>
      <plugin>
       <artifactId>maven-plugin-plugin</artifactId>
       <version>2.3</version>
       <configuration>
         <goalPrefix>weblogic</goalPrefix>
       </configuration>
      </plugin>
    </plugins>
  </build>
 
</project>

    3. From within MW_HOME/wlserver_10.3/server/lib/, run the mvn install command.

      This step sets up the local Maven environment to allow the plug-in to use the weblogic prefix.

      mvn install

    4. From within MW_HOME/wlserver_10.3/server/lib/, provision the weblogic-maven-plugin.jar in your local Maven repository, as follows:

      mvn install:install-file 
-Dfile=MW_HOME/wlserver_10.3/server/lib/weblogic-maven-plugin.jar -DpomFile=pom.xml

    5. Now, you can use a shortened command-line goal invocation, such as:

      mvn weblogic:deploy

Supplying Secure User Credentials

In order to connect to the WebLogic Server domain to perform deployment operations, the weblogic-maven-plugin must supply valid user credentials. For quick and simple cases, this is typically done by specifying the user name and password directly in the Maven pom.xml file, as shown in Example C-1. However, this results in the user name and password entries being stored in clear-text form. To avoid this password exposure, you can optionally use a secure configuration authentication mechanism which stores the user name and password in encrypted form in an external file, and then uses it to supply the user credentials with which to connect to the WebLogic Server domain, along with the key that was used to encrypt the file. For more information, see "Securing Access from WLST Online" in Oracle WebLogic Scripting Tool and "User Credentials Arguments" in the weblogic.Deployer Command-Line Reference.

The following steps show you how to create and store a user configuration file and key file using WLST, and how to reference them in the Maven pom.xml file.

  1. Invoke WLST, connect to a running Administration Server, and use the WLST storeUserConfig command to specify the locations of the userConfigFile and userKeyFile that will be generated.

    >java weblogic.WLST
wls:/offline>connect('weblogic','welcome1')
wls:/mydomain/serverConfig>storeUserConfig('/tmp/wls.config','/tmp/wls.key')
Creating the key file can reduce the security of your system if it is not kept in
a secured location after it is created. Do you want to create the key file? y or n
y
The username and password that were used for this current WLS connection are
stored in /tmp/wls.config and /tmp/wls.key

    You can validate that these files work correctly using weblogic.Deployer to connect to the WebLogic Server domain, using the -userconfigfile and –userkeyfile parameters, as follows:

    java weblogic.Deployer -adminurl t3://localhost:7001
-userconfigfile /tmp/wls.config -userkeyfile /tmp/wls.key –listapps

  2. To use the secure configuration authentication mechanism with the WebLogic Maven plug-in, you must install an additional library, <MW_HOME>/modules/crypto.jar, into the Maven repository to support the encryption operations, then add it as a dependency of the weblogic-maven-plugin via its pom.xml file.

    1. Install crytpo.jar into the Maven repository, as follows:

      cd <MW_HOME>
cd modules
mvn install:install-file -Dfile=cryptoj.jar -DgroupId=com.oracle.cryptoj
-DartifactId=cryptoj -Dversion=1.0 -Dpackaging=jar

    2. To generate the weblogic-maven-plugin and its pom.xml file, follow steps 1 and 2 in Configuring and Using the WebLogic Maven Plug-In.

    3. Edit pom.xml to specify the crytpo.jar dependency and goalPrefix, a configuration section that lets you use the shortened command-line goal invocation of the plug-in.

      See Example C-3, an edited pom.xml file with changes at lines [16-22] and [24-35].

33:        </plugin>
34:      </plugins>
35:    </build>
36:  </project>

  3. Install weblogic-maven-plugin into the Maven repository by using the following two install commands. The first command implicitly uses the edited pom.xml file and configures the weblogic-maven-plugin inside the Maven repository. The second command performs the installation of the weblogic-maven-plugin library into the Maven repository.

    Ensure that the edited pom.xml file is in the directory in which you will execute these commands.

    For Maven 2.x:

    mvn install
mvn install:install-file -Dfile=weblogic-maven-plugin.jar -DpomFile=pom.xml

    For Maven 3.x:

    mvn install -Dfile="weblogic-maven-plugin"
mvn install:install-file -Dfile=weblogic-maven-plugin.jar -DpomFile=pom.xml

  4. Configure pom.xml to use the secure configuration files for authentication.

    Example C-4 shows a fully configured Maven pom.xml for a Java EE 5 Web application. Lines [13-18] show the creation of the properties that identify the location of the relevant external files generated from WLST. Lines [67-69] show the use of the <userConfigFile> and <userKeyfile> elements to specify using the secure configuration files for authentication.

  5. Verify that the secure configuration authentication mechanism works by using the weblogic:list-apps goal—This goal doesn't perform any deployment operation, but does connect to the target server, authenticates, and returns a list of the currently deployed applications.

    Note the [INFO] output which shows the underlying weblogic.Deployer command that is issued, in which the –userconfigfile and –userkeyfile parameters are used.

Troubleshooting

Table C-8 describes some common Maven plug-in errors and helps you resolve them.

Table C-8 Maven Plug-In Errors

Configuration Step Error Message Resolution

Step 1: Generating the plug-in.

java –jar wljarbuilder.jar –profile weblogic-maven-plugin

Unable to access jarfile wljarbuilder.jar

Make sure that you have issued the command from within the MW_HOME/wlserver_10.3/server/lib/ directory.

Step 2: Extracting the pom.xml file from weblogic-maven-plugin.

  

The pom.xml file is created in MW_HOME/wlserver_10.3/server/lib/META-INF/maven/com.oracle.weblogic/weblogic-maven-plugin/pom.xml. From this location, you must copy the pom.xml file to MW_HOME/wlserver_10.3/server/lib/ (see Step 2 in Configuring and Using the WebLogic Maven Plug-In).

Step 3: Provisioning the weblogic-maven-plugin.jar in the Maven repository.

If the provisioning is successful, you will see a Build Successful message.

Build Error

The possible issues are:

Step 4: Executing Maven goals.

If successful, you will see a Build Successful message.

Failed to resolve artifact

The possible issues are:

  • You must run the mvn install command at least once before invoking mvn weblogic:goal. This is required because there are Maven dependencies which must be retrieved from the Internet (see the Note in Step 3 in Configuring and Using the WebLogic Maven Plug-In).

  • You have executed the mvn install command from a location other than MW_HOME/wlserver_10.3/server/lib/.

  • There was no pom.xml file found under MW_HOME/wlserver_10.3/server/lib/.

Step 5: Using the shortened name goal invocation of the plug-in.

For example:

$ mvn weblogic:help

Build Failure

[ERROR] Could not find goal 'help' in plugin org.codehaus.mojo:weblogic-maven-plugin:2.9.1 among available goals...

The most likely cause is that you have not followed Step 5 in Configuring and Using the WebLogic Maven Plug-In in its entirety.

  • Make sure that you have extracted the pom.xml file and edited it to add the additional <build> stanza:

    <build>
   <plugins>
      <plugin>
       <artifactId>maven-plugin-plugin</artifactId>
       <version>2.3</version>
       <configuration>
         <goalPrefix>weblogic</goalPrefix>
       </configuration>
      </plugin>
    </plugins>
  </build>

  • Make sure that you have performed the required mvn install after editing the pom.xml file, but before issuing the mvn install:install-file command.

If this error occurs, you can remedy it by simply going back and following Step 5 exactly as written:

  • Extract pom.xml from weblogic-maven-plugin.jar

  • Edit pom.xml to add the <build>...</build> stanza

  • Execute mvn install

  • Execute mvn install:install-file -Dfile=weblogic-maven-plugin.jar -DpomFile=pom.xml
