Description acscheiner 2003-12-17 15:18:45 UTC 
Build Number: NetBeans IDE 3.5.1 (Build 
200307302351);
JDK: 1.4.2;

NB IDE was installed on my WinXP system (this 
system did have a prior version of NB installed, 
but it was uninstalled prior to the 3.5.1 
install and nothing from that install was 
imported into my 3.5.1 install). I used all the 
defaults for installing & running the IDE (e.g., 
I did not modify the ide.cfg file from it's 
default setup). As such, NB set up its home 
directory and the userdir under "C:\Documents 
and Settings\<myUserName>".

I created a new NB project and mounted a Local 
Directory type Filesystem for this project. The 
mounted directory contained a tree of 
subdirectories with .java, .class, .jsp, .html, 
javascript, and other types of data and source 
files.

I right-mouse-clicked on an html file to bring 
up the context menu and selected Execute (F6) 
from the context menu. A message box immediatly 
appeared indicating that an error had occured, 
and the details of the error are as follows:

Additionally, I tried to create a new context 
under the NB Explorer "Runtime/Server 
Registry/Installed Servers/Tomcat/Internal 
Tomcat (4.0.6)/localhost:8081" node. No error 
message was popped to the IDE, but no context 
was created.

The ide.log file for this entire series of steps 
is as follows:

After searching the nbusers list, I did find a 
number of other users who had posted on this 
issue. I was able to resolve/work-around this 
problem by specifying the -userdir parameter in 
my ide.cfg file such that it pointed to a 
different directory than my "C:\Documents and 
Settings\<myUserName>" home directory. The 
redirected userdir did not contain any 
whitespace characters in the path as this was 
suggested as a possible source for the 
NullPointerException being thrown by the 
Tomcat40DataObject.setNewContext method. 
Empircally, this fix worked for me as well, but 
I did not do sufficient experimentation to 
verify the theory that whitespace in the userdir 
path name is definitely the source of the 
problem.

I discussed this problem via email with Petr 
Jiricka (among others) and he suggested I enter 
this issue in the NB issuezilla system. Thus, 
here it is.
Comment 1 Milan Kuchtiak 2004-01-12 12:59:31 UTC 
This issue want be fixed because of replacing Tomcat4 with Tomcat5
plugin. There is a different handling of servlet contexts.
Comment 2 Milan Kuchtiak 2004-01-12 13:52:27 UTC 
The problem was likely caused by different XML parser that was used.
Comment 3 Milan Kuchtiak 2004-01-12 13:59:39 UTC 
See also the #29625.
