Adding libraries to the EAR library directory

About this task

Important: Applicable to Liberty, WebSphere® Application Server traditional

Procedure

Open the pom.xml file in the POM editor by double-clicking the file. Click the pom.xml tab to work directly with the source.

Set the lib directory to be used in the EAR project.

Add the element <defaultLibBundleDir> to the configuration of the maven-ear-plugin as in this example:

<plugins>
   <plugin>
      <artifactId>maven-ear-plugin</artifactId>
      <version>2.7</version>
      <configuration>
         <version>6</version>
         <defaultLibBundleDir>lib</defaultLibBundleDir>
      </configuration>
   </plugin>
</plugins>

Save the pom.xml file.
Use quick fixes to resolve any errors.
After you save the pom.xml file, you might see the following errors in the Problems or Markers view:
- Library Directory "<PATH_TO_LIB_FOLDER>" does not exist.
- Project configuration is not up-to-date with pom.xml. Run Maven->Update Project or use Quick Fix.
Right-click the errors and select Quick Fix to resolve the errors.
Place JAR files in the lib directory.
If the lib directory is specified for the EAR project in the <defaultLibBundleDir> element, then all dependencies to JAR artifacts are bundled in the lib directory by default. However, if you want to place a JAR file in a different location, you can use the <jarModule> element to specify a different location.
For example, the following fragment of pom.xml shows that the EAR project uses lib as the default directory to bundle JAR files:
```
<plugin>
   <artifactId>maven-ear-plugin</artifactId>
   <version>2.7</version>
   <configuration>
      <version>6</version>
      <defaultLibBundleDir>lib</defaultLibBundleDir>
```
In the following example, the pom.xml file has a dependency to a shared library that is packaged in lib and a dependency to an EJB client JAR file that is bundled at the root of the EAR file. Without further changes, both are bundled in the lib directory by default.
```
<dependencies>
  	<dependency>
      <groupId>testapp</groupId>
      <artifactId>ejbclient</artifactId>
      <version>0.0.1-SNAPSHOT</version>
   </dependency>
   <dependency>
      <groupId>testapp</groupId>
      <artifactId>SharedLib</artifactId>
      <version>0.0.1-SNAPSHOT</version>
   </dependency>
</dependencies>
```
The following example shows how to change the location of the EJB client JAR file:
```
<plugin>
   <artifactId>maven-ear-plugin</artifactId>
   <version>2.7</version>
   <configuration>
      <version>6</version>
      <defaultLibBundleDir>lib</defaultLibBundleDir>
      <modules>
         <jarModule>
            <groupId>testapp</groupId>
            <artifactId>ejbclient</artifactId>
            <bundleDir>/</bundleDir>
         </jarModule>
      </modules>
   </configuration>
</plugin>
```
This example shows that the default bundle directory for JAR files is lib, but the EJB client JAR file for <artifactId>ejbclient</artifactId> is in the root of the project. The bundle directory is indicated with <bundleDir>/</bundleDir>.
