#  Adding a JavaAgent

Adding a java agent is done via a vm parameter as follows:

{panel}
java -javaagent:openejb-javaagent-3.0-beta-2.jar _\[other params...](other-params....html)
_
{panel}

{note:title=Need the JavaAgent?}
The java agent is only required if using OpenJPA as your persistence
provider or if using CMP.

##  Maven2

In maven2 you can enable the javaagent for your tests by adding this to
your pom.xml file:

    <build>
      <plugins>
        <!-- this configures the surefire plugin to run your tests with the javaagent enabled -->
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <configuration>
            <forkMode>pertest</forkMode>
            <argLine>-javaagent:${basedir}/target/openejb-javaagent-3.0-beta-2.jar</argLine>
            <workingDirectory>${basedir}/target</workingDirectory>
          </configuration>
        </plugin>

        <!-- this tells maven to copy the openejb-javaagent jar into your target/ directory -->
        <!-- where surefire can see it -->
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
