Work Around: 
Never create JSPs under the "classe" directory.
In fact, the IDE should not allow this at all...
Also, if when mounting web modules in the IDE, the check should be done and a
nice error should be emitted.

Evaluation: 
the nicer dialog will be shown

in Doublin it will not be a problem; the webResourceImpl will not be used

Transferred from BugTraq 4721126.

Comment 2 _ rkubacki 2003-02-06 08:15:41 UTC

Webdata was Damian's responsibility so maybe Martin can look into
this. Hopefully we will not use it for new version.

Comment 3 Petr Jiricka 2003-02-12 15:09:58 UTC

The first exception does not happen any more - I can not 
reproduce it. The second one still occurs, but I can not 
think of a way to avoid it. Using Projects is crucial for 
this fix.

Comment 4 psuk 2003-02-28 18:11:57 UTC

Setting Target Milestone to 4.0 (Projects Infrastrucure)

Comment 5 Petr Jiricka 2004-01-28 20:46:39 UTC

Now it's not possible to create a JSP under the classes directory ->
fixed.
