typically I set a breakpoint in my Java application when I want to observe the run.
However sometimes I just want to know if a method is called or not. Therefore a breakpoint does not help me, and I insert a "systrace" statement
System.out.println("method signature");
I thought it would be a nice feature If I could set a breakpoint and when the breakpoint is reached to just print out the systrace message and continue the run.
Do you know if this is possible?

Right Click the project and Open Properties. Then Select Run/Debug Setting from there you will find all the launch Configured. Delete all the launch and Run the application.
To create a conditional breakpoint, first set a breakpoint on a line (Ctrl+Shift+B), right-click on the breakpoint and select Breakpoint Properties. Then configure a condition that returns a boolean. Eclipse only stops if the conditions returns true.
Go to Run->Debug Configurations then double click on “Remote Java Application”. Now enter a name for the configuration and fill in the project name, for the project you want to debug on the server, the host (“localhost”, usually) and the port number (this will be 7777, by default but you can check in the WAS console).
To debug your application, select a Java file with a main method. Right-click on it and select Debug As Java Application. If you started an application once via the context menu, you can use the created launch configuration again via the Debug button in the Eclipse toolbar.
But Eclipse does provide other conditions to cater for the other situations. If you want to stop a breakpoint only after the line has been executed a certain number of times, select Hit Count and enter a number. This is handy for running through loops where you’re only interested in, say, the 2nd iteration.
b) Your breakpoint is crossed out. That means you activated the Eclipse feature ‘Skip All Breakpoints’ that can be used to make ALL breakpoints non-functional. Deactivate the ‘Skip All Breakpoints’ feature via main menu ‘Run’ -> ‘Skip All Breakpoints’. Alternatively use the buttons in the Eclipse main toolbar or in the breakpoints view toolbar.
A new feature in the Eclipse Platform that allows users to creates conditional breakpoints to print out messages without halting at the breakpoints and cluttering the code base. The Eclipse Platform created tracepoint with systrace template.
How to create a conditional breakpoint To create a conditional breakpoint, first set a breakpoint on a line (Ctrl+Shift+B), right-click on the breakpoint and select Breakpoint Properties. Then configure a condition that returns a boolean. Eclipse only stops if the conditions returns true.
You have to make it a conditional breakpoint with a following condition:
System.out.printf(Thread.currentThread().getStackTrace()[1].getMethodName() + "\n") == null
Works fine in my Eclipse. I'm using printf to make printing code evaluate to boolean. Not sure if there's a way to automate inserting this code into a breakpoint.
