When developing OSGi Plugins, you should have your own development server running on your local machine. Not only because of the faster deployment of changes (a new version of a plugin must always deployed with a HTTP restart), but because of the Java debugging posibilities: Only one Eclipse instance can connect to the JVM, and every request processed by the server will start the debugger. If multiple users a accessing the server while you are debugging, your Eclipse will try to debug every incoming request, and this can lead into a confusing situation for all.<\/p>\n

To enable debugging, you first have to add two parameters to the notes.ini<\/em>:<\/p>\n

JavaEnableDebug=1\r\nJavaDebugOptions=transport=dt_socket,server=y,suspend=n,address=8000<\/code><\/pre>\n
This starts the debugging on port 8000. Feel free to change the value to every port you want. Because of security reasons you should not start debugging on a productive machine.<\/p>\n
After restarting the domino server, you can connect to the JVM in your Eclipse IDE by creating a new JVM remote debugging session. Create a new debug configuration…<\/p>\n
\"\"<\/a><\/p>\n
… choose (1) „Remote Java Application<\/em>„, (2) give a name to it, (3) select the plugin project, (4) enter the port the server listens, and click on (5) „Apply<\/em>„.<\/p>\n
\"\"<\/a><\/p>\n
If you want to connect to your server, you need to start debugging by clicking on the project:<\/p>\n
\"\"<\/a><\/p>\n
After setting a breakpoint and sending a request to the servlet, Eclipse switches to the Debug perspective where you can look what happens with your servlet.<\/p>\n
\"\"<\/a><\/p>\n
Sometimes you are connecting to the „wrong“ JVM, because a Java agent is running and\/or a DOTS task does it’s job. It’s better to disable these tasks on your development server.<\/p>\n
During debugging you are able to hotswap your code<\/a>, but keep in mind that after a restart of the HTTP JVM all your changes are no longer „installed“. You have to build a new plugin or replace your code during runtime again.<\/p>\n
