Case

You have to enable JMX in an application deployed within WebLogic, so that to access MBeans from Java Visual VM for instance

Solution

On launching WebLogic server instance, add the following properties:

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8888 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

Case

You need include tools.jar as a dependency in a pom.xml, for instance in order to use Java 5’s annotations and APT. From a “Maven’s view point”, tools.jar is not a regular JAR defined by a groupId and artefactId.

Solution

Add this block in your pom.xml:

<dependency>
    <groupId>com.sun</groupId>
    <artifactId>tools</artifactId>
    <version>1.6.0_24</version>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

(You can also add it in your settings.xml)

You can do the same for any other “non-regular” JAR, available in your file system.
