debugging one's custom tags [message #41414]

I was hoping to launch my usual transformation in 'debug' mode rather
than 'run' and to be able to set breakpoints in my custom tags code.

I can't see a way to do this.
Am I missing something ?
What do the JET developers do ?

Edoardo:

No, there is no debug mode. (Are there any volunteers to write a JET
debugger?)

If, as your subject line suggests, you are debugging custom tags, launch a
'runtime' workbench (in debug), and put break points in the JET tag handler
methods you are working on. Then run a JET transformation from that runtime
workbench. Note that the JET transformation can be in you development
workbench - it is a plug-in, and can be included in the runtime workbench as
any other.

Other things I do for debugging are:

1) use <c:log></c:log> to write debug messages in my templates.

2) In the jet launch config, set the logging level to trace or debug - this
generates a whole lot more information on the execution consule. (The
utility of that information may be debated.)

It has been several years since I have put breakpoints directly in the Java
code generated from a template (but then, I never write in-line Java
scriptlets or expressions).
