Menu
For a J2EE bean I am reusing code that was developed for a java swing application. JOptionPane.showMessageDialog() is unfortunately commonly used. Most occurences luckily in code sections that are not reused by the J2EE application, but in some cases lower levels of the code has instances of JOptionPane.showMessageDialog(). Obviously this it results in dialog boxes popping up on the server, which is what I want to avoid.
As a first step I'd like to somehow assure that no dialog boxes will ever occur on the server.
Someone suggested peeking in some event or paint queue (I do not recall which one): That would be:
// old code: JOptionPane.showMessageDialog(msg);
if ( someEventQueue.size() == 0 ) // <== consider this pseudo-code
Log.log(msg); // I am running on a server. Tell the log.
else
JOptionPane.showMessageDialog(msg); // I have a user made of meat. Tell him!
I never really got that working. What would you do?

If you want to check the work of java application, run 'ps' command with '-ef' options, that will show you not only the command, time and PID of all the running processes, but also the full listing, which contains necessary information about the file that is being executed and program parameters.
You can do that by opening the "Open Run Dialog" ("Run" menu), then select your type of application and add in the "Arguments" tab a -DrunInEclipse=true . In your Java code, you can check the value of the property: String inEclipseStr = System. getProperty("runInEclipse"); boolean inEclipse = "true".
Make sure the server is started with
java -Djava.awt.headless=true
Most servers should be started that way by default. Then you can check:
boolean headless_check = GraphicsEnvironment.isHeadless();
More details on headless available here:
