How to test Java Servlets !

[SrinivasaRao Sanagapalli]

Hi,
I have question of which software I need to download inorder to test simple Java Servlets. I go to the Java site it is saying I need to install J2EE. But after all loading it is like GUI interface there we need to go so many steps inorder to run a simple Servlet. How can I test servlets other than using J2EE !
Greatly appreicate the reply.
Thanks

just download tomcat the free web server that supports servlets. that with a regular J2SE is enough.

I couldn't understand why it is coming like this.
Thanks

If you're having problems with Tomcat (which it would appear that you are), you'd probably get a better response in the Apache/Tomcat forum.

You get this error because it is already running as a service on the back ground. So, go to services window and swicth Tomcat to run on manual mode.

Hi,
I think the problem is with the port number. I had Oracle in my machine. When I used the http://localhost:8080 some oracle related stuff is coming up. I think the 80 port is using Oracle. How to use the other and how can I choose and if I choose one how to call the servlets like instead of http://localhost:8080 we need to use other alternative.
Appreciate the reply
Thanks

In tomcat 4.0.4 beta 3
there is a file under C:\Apache Tomcat 4.0\conf called server.xml in that xml change the 8080 to whatever value you want in the following tag.
<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="8080" minProcessors="5" maxProcessors="75"
enableLookups="true" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="60000"/>
<!-- Note : To disable connection timeouts, set connectionTimeout value
to -1 -->

Thanks a lot. It worked now.
I changed the port 8080 to 8090 now it is working. I think Oracle in my system is using 8080 port.
Anyway thanks a lot.
