I have found EPIC for Eclipse as promising development tool for coding and debugging otrs.
Just as for Java (which is more my base

I tried like this.
1. First did a normal OTRS3 install on my disk (windows).
2. Created a perl project in eclipse and importet just the OTRS\OTRS directory (which directly contains the KERNEL dir).
3. Created a RUN Configuration and startet the index.pl
Result was a response in the browser, saying that my browser is far too old and cannot be used

I am sure, I did something wrong configuring the environment, because I did not completly understand everthing yet.
Could anyone "help me on the horse" and give me some hints, about how to start this?
Maybe you use different dev-tools and would like to share your experience with me?
I am open minded, but need a solution, that alows me to start coding and debugging inside the app and not just with adding println.
Cheers,
Joern
