Stepping into java runtime classes [message #106309]

Hello

I think that I understand the concept of step filters quite well. But it
does not seem to work the way documented. Even though I have step
filtering disabled I cannot step into any of the classes of the java
runtime system. Does anybody know how to do this.

Thanks. Mike

I think we need some more details about it, because stepping into
library code is definitely something a lot of users do every day.
Help us narrow down what is different about your case...

HTH,

Thank you for answering. I want to stepping into library functions such as
java.util.ArrayList.add . I got the idea that step filter simply exist to
prevent someone from stepping into a function like this, because this code
is usually not what one is interested in. But even though I played around
with the step filter settings a lot, the debugger simply executed this
code as one step. It seems to me that the step filter setting are a
placebo.

It sounds as if you understand what step-filtering is for - to make
debugging easier by not stepping into certain packages/classes that are
uninteresting.
However, stepping into core Java code is something that many people do
every day, so it's not clear to me why you're having trouble.

Here is a screencast showing stepping into ArrayList:
http://www.rizzoweb.com/Eclipse/DebuggerStepping.html

Does that help you determine what you're doing differently?

One more question, are you using a JDK with source to run Eclipse and
your application within Eclipse? IF you're using a JRE and not a JDK,
perhaps Eclipse is skipping the core Java classes that it knows there is
no source for...<shrug>

HTH,
Eric

This was the problem. By default eclipse use the following JRE
C:\Programme\Java\jre1.5.0_04 I changed this to the JRE
C:\Programme\Java\jdk1.5.0_04\jre and everything works out fine.

Thanks. Mike
