Debugging ApacheMQ/Camel

• Change activemq.bat by removing comment for the following line:
• SET ACTIVEMQ_DEBUG_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
• start ActiveMQ through command line
• create a Maven project with NetBeans
• add the required dependencies to project according to the modules you want to debug (the sample is for ActiveMQ 5.9 and cxf, scripting/Groovy and stream):

    <dependencies>

        <dependency>

            <groupId>org.apache.camel</groupId>

            <artifactId>camel-cxf</artifactId>

            <version>2.12.1</version>

        </dependency>

        <dependency>

            <groupId>org.apache.camel</groupId>

            <artifactId>camel-script</artifactId>

            <version>2.12.1</version>

        </dependency>

        <dependency>

            <groupId>org.apache.camel</groupId>

            <artifactId>camel-stream</artifactId>

            <version>2.12.1</version>

        </dependency>

        <dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-transports-http-jetty</artifactId>

            <version>2.7.8</version>

        </dependency>

        <dependency>

            <groupId>org.codehaus.groovy</groupId>

            <artifactId>groovy-all</artifactId>

            <version>2.2.1</version>

        </dependency>

        <dependency>

            <groupId>org.eclipse.jetty.aggregate</groupId>

            <artifactId>jetty-all-server</artifactId>

            <version>8.1.14.v20131031</version>

        </dependency>            

        <dependency>

            <groupId>org.eclipse.jetty</groupId>

            <artifactId>jetty-websocket</artifactId>

            <version>8.1.14.v20131031</version>

        </dependency>

• build the project so the dependencies are downloaded to local maven  repository
• in NetBeans go to Dependencies and select Download Sources
• in NetBeans go to Debug menu and choose Attach Debugger
• chgange the port to 5005 (or whatever was specified in ACTIVEMQ_DEBUG_OPTS)
• look for the desired package/class in Dependencies, open the class, place a breakpoint, etc
