Can not run Tmacat on Win2k

[Richa Goyal]

When i run tomcat on windows by command prompt the following eceptions occur.
I have set the JAVA_HOME and CATALINA_HOME paths correctly.
my jdk is jdk1.3. The tomcat 4.0.6 requires jdk1.2.x or above.

Kindly tell me the solution.

Looks like the xml document is not well-formed.
<element_name />
D:\Apache Tomcat 4.0\conf\tomcat-users.xml
Here is mine, which has been untouched.
<tomcat-users>
<user name="tomcat" password="tomcat" roles="tomcat" />
<user name="role1" password="tomcat" roles="role1" />
<user name="both" password="tomcat" roles="tomcat,role1" />
</tomcat-users>
http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/
has a decent set of instructions for Tomcat.

Thanks for your suggestion. My tomcat_users.xml file was blank. I added your codes to it. BUt now i m getting another set of error about port 8080 already in use.

What is the problem

[William Brogden]

If those ports are already in use you probably have instances of Tomcat already running. Did you install as a service? What do you see when you look at the running processes?
