Project: Tomcat
Category: Bug Report
SubCategory: New Bug Report
Class: swbug
State: received
Priority: high
Severity: non-critical
Confidence: public
Environment: 
   Release: 3.1
   JVM Release: IBM JDK 1.3
   Operating System: Linux (Mandrake)

Synopsis: 
multiple instances of tomcat running on different ports erroniously over write each others JSP metafiles by both using the work/localhost_8080/ forlder rather than naming the folder of the port they are actually using

Description:
I am running two instances of tomcat so that I can 
can have two people on the same machine develop a java
project.  Here are my server.xml files.

as you can see the only difference is the docBase
and the port they listen on.  Now I then browse to
http://localhost:8081/index.jsp and http://localhost:8082/index.jsp
and get the same page even tho the .jsp's are different.
If it do a `find .` in the work directory this is what I 
see.

[root@angband work]# find .
.
./localhost_8080%2Fexamples
./localhost_8080%2Ftest
./localhost_8080%2Fadmin
./localhost_8080
./localhost_8080/_0002findex_0002ejspindex_jsp_0.java
./localhost_8080/_0002findex_0002ejspindex.class

As you can see, only one java file has been
produced not two, it happens to be the one 
corosponding to the first page I checked.  Also note
that the port is 8080, the default.  Had the real
ports been used "8081" and "8082" there would
not be a collision and this would have worked.
I am no tomcat kung fu master but this looks really
fishy to me. 

Lastly I deletee the work directory and got this
message on both browsers.


Error: 404

Location: /index.jsp

JSP file "/usr/local/jakarta/build/tomcat/work/localhost_8080/_0002findex_0002ejspindex_jsp_0.java (No such file or directory)" not found 

Confirming that they are both indeed looking for the same file.

Grepping the code for 8080s was to no avail,
I need to leave this to someone who knows the code base.

Thanks a lot.
