How to compile servlets

[Sue Pillai]

Hi,

Are my path & classpath correct for compiling servlets?

I downloaded the J2EE1.4 s/w bundle that includes

# Sun Java System Application Server Platform Edition 8.1 2005Q1
# J2SE 1.4.2
# J2EE 1.4 SDK Samples 2005Q1
# J2EE 1.4 API Documentation

I have also downloaded the tomcat 5.5.7 and the compat versions, set the java-home variable and got the tomcat welcome page successfully.

My path is set to:

c:\sue\projects\exercise\servlets;c:\J2EE1.4\bin;
c:\J2EE1.4\jdk\bin;c:\J2EE1.4\jdk\jre\bin;

My classpath is set to:

c:\sue\projects\exercise\servlets;c:\J2EE1.4\lib;
c:\J2EE1.4\jdk\lib;c:\J2EE1.4\jdk\jre\lib;

The first path is my working directory. The compilation error is package javax.servlet does not exist; package javax.servlet.http does not exist; It also points at all other places where the servlet classes are used.

Where am i going wrong? Do I need to download something else?

With Tomcat, you don't need j2ee.
Don't know if it hurts but take it out for now.

Add TOMCAT_HOME/common/lib/servlet-api.jar to your classpath and try compiling.
Tomcat ships with the j2ee components it needs.

Let us know

Thanks, it did compile after adding the classpath you mentioned.

The next question as you can guess is how to run the servlet on tomcat. I am used to javawebserver where we put the class files in servlets directory and htmls in public_html.

How does it work in tomcat? If it is complicated can somebody provide a link for a good read on how to run servlets on tomcat? Thanks again!

TOMCAT_HOME/webapps/YOUR_APP
TOMCAT_HOME/webapps/YOUR_APP/jsps, html, etc..
TOMCAT_HOME/webapps/YOUR_APP/WEB-INF/web.xml
TOMCAT_HOME/webapps/YOUR_APP/WEB-INF/classes/YOUR_PACKAGE/YOUR_CLASSES
TOMCAT_HOME/webapps/YOUR_APP/WEB-INF/lib/JAR_FILES..

It's covered here:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/appdev/index.html

Also, I've published some simple war file examples that you can download and run. The directory structures and web.xml files in them are correct.

You might find the following useful as well:

And there are probably no better books on the subject of servlets/jsp (tutorial type) than Kathy Sierra and Bert Bates' book: http://www.amazon.com/exec/obidos/ASIN/0596005407/qid=1108089062/sr=2-1/ref=pd_ka_b_2_1/104-2470500-1671162
