It's legitimate for developers to experiment with the server configuration, properties, etc. Tomcat is free, you don't have to pay anything for extra installations. Forcing developers to share installations restricts their options during development (or at least slows down the process if they have to make sure their config change is OK with all other developers using the server). If one developer's mistake crashes the server, everyone suffers. If he has his own server, no one else is interrupted when it crashes. Finally, sharing the same tomcat instance doesn't gain you any significant advantage. Of course, there should be a shared/central integration testing server.

Shapira, If I'm not too demanding :-) can you please explain why it is a bad idea to use the same Tomcat instance for more than one user. Is it performance related or is it something else ?

Take the rest of your configurations, especially the Loader, out of server.xml. A better alternative is to have a completely separate tomcat instance for each developer.

How do I specify a different workDir for each user accessing the same Tomcat 4.1.27 implementation
Hi, I am trying to manage a development team wherein each user uses the same instance of Tomcat for development. I do this by having a different server.xml file for each user and having the context docBase point to the build/webapps directory of each user, like shown below: Now I want to specify a different workDir for each user also. How do I do that? I tried adding the following element inside the but it doesn't work: I want to do this as all JSP pages are now being compiled into the same work directory for every user. So if two or more users are concurrently working on the same JSP page they sometimes end up with a feature that they never added! (and which someone else working on the same JSP page might have added). So they ask me the question "Hey, I didn't add this... How did that thing get in there?". And that triggered me into thinking that if I can specify a different workDir for each user the problem will be solved... Is this really do-able ?

RE: newbie jasperException
Chrish,
Thanks for finding time to reply to my question. After some hours of
churning the jsp code around I tracked down my mistake to not passing a
command line property (-Dpos.home-...) to the JVM. When I set this property
using CATALINA_OPTS=-Dpos.home=... I got the output.
Thanks again.
Regards,
Goutam

Hi,
Your JSP code is wrong. The <%@ page import... %> directive needs to go at
the top of the page. When the Jasper compiler turns it into Java, that
directive gets turned into one or more Java import statements, and you
wouldn't stick those in the middle of your code.
Remember, all the HTML gets turned into Java code, as follows:
out.write("\r\n\r\n...");
So that your import statements (and the class variable declaration "<%!
Vector v; %>") appear inside a servlet doGet() method, which is illegal
Java. In spite of the superficial similarities, JSP is not really like PHP.
The PHP interpreter turns embedded PHP code into HTML, while the JSP
compiler turns HTML into Java (and then the Java compiler turns it into byte
code). It will help you to keep this in mind when writing JSP code.
BTW, I'm a little troubled by that "<%! Vector v; %>" declaration. This
turns v into an instance variable of the servlet class that Jasper creates.
Is this what you intended? If not, remove the exclamation mark and leave
the variable declaration where it is.
Kind regards,
Chris Williams.

Hi,
I am getting the following JasperException. (Please scroll below for the
exception :-) ). I am relatively new to jsp. Can anyone please point me as
to what's going wrong here?
FYI I am including the jsp code also.
<-jsp code>
function textSelected()
{
option=document.forms[0].PoRefno.options[document.forms[0].PoRefno.selectedI
ndex].text
document.write("This is the selected text" + option)
}
<%@ page
import="deshaw.fats.collection.database.PurchaseOrderDbCollection,
java.util.*,java.sql.SQLException"%>
<%! Vector v; %>
<%
try{
v=new PurchaseOrderDbCollection().getPoRefNos();
}
catch(SQLException e)
{ %>
<% } %>
<%
Iterator i=v.iterator();
String s;
while(i.hasNext()) {
s=(String) i.next();
out.write("" + s + "");
}
