Doubt in servlet

[preetiarvind sharma]

Hi All,
I m trying to develop a really basic servlet. My application structure goes like this.

test - root
webapps - test - WEB-INF - web.xml
webapps- test - WEB-INF - test.jsp
webapps - test - classes - servlets - TestServlet.class
webapps - test - classes - beans - TestBean.class

Here I cant call my servlet directly from the Address basr using this URL
http://localhost:8080/test/TestMe

What wrong am i doing here??
Pls help.

here is the copy of my web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
<display-name>Welcome to Tomcat</display-name>
<description>
Welcome to Tomcat
</description>

<servlet>
<servlet-name>Test</servlet-name>
<servlet-class>servlets.TestServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>test/Testme</url-pattern>
</servlet-mapping>
</web-app>


Regards,

Preeti

<url-pattern>test/Testme</url-pattern>

change to

<url-pattern>/test/Testme</url-pattern>

and try this...


and one more

webapps- test - WEB-INF - test.jsp
to
webapps- test - test.jsp

place all jsps file under test

[Vishnu Prakash]

 

webapps - test - WEB-INF - web.xml

Correct

webapps- test - WEB-INF - test.jsp

Wrong.(This is correct but can't be accessed directly.) Correct it to
webapps- test - test.jsp.

webapps - test - classes - servlets - TestServlet.class

Wrong. Correct it
webapps - test - WEB-INF - classes - servlets - TestServlet.class

webapps - test - classes - beans - TestBean.class

Wrong. Correct it(put all classes in one package)
webapps - test - WEB-INF - classes - servlets - TestBean.class

Here I cant call my servlet directly from the Address basr using this URL
http://localhost:8080/test/TestMe

Correct the URL to
http://localhost:8080/MyWebApplication/test/TestMe

<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>test/Testme</url-pattern>
</servlet-mapping>

url-pattern element is Wrong. Correct it to

<url-pattern>/test/Testme</url-pattern>

Note: I had a slash in front of test.

Thanks Vishnu and RaghuNath for ur replies.
First of all aplogies for the little mistake in the file structure i have provided initially

my jsp is actually in 'test' and not WEB-INF .. so its test/test.jsp
and classes are in the WEB-INF directory as separate folders for beans and servlets.

Vishnu - i have tried /test/TestMe . It didnt help.
do i have to give the package name (servlets) since servlet in inside a pkg. Btw i have tried that, i dont think I am using the right URL?

RaghuNath - I wanted to keeps my beans separate from the servlets, thats why I have created two packages inside the classes. I dont think thats wrong?? Your suggestions please.

Hi preetiarvind -

if you look closely at what Vishnu wrote, you'll see that you need to put your class files inside a directory called classes within WEB-INF. This classes directory is part of the classpath, so what packages you put inside there will be picked up by the servlet container. If you wish to have your own package structure inside this, go ahead.

Vishnu - i have tried /test/TestMe . It didnt help.
do i have to give the package name (servlets) since servlet in inside a pkg. Btw i have tried that, i dont think I am using the right URL?

your url-pattern needs to start with a slash as pointed out. However, it need not reflect your physical package structure - the whole point is that it's declarative, so that you could change the back-end package structure without affecting the front-end.

I Assuming you have tomcat running on port 8080, think you should be able to get to your servlet with http://localhost:8080/test/test/Testme

http://localhost:8080/test

should get you to the root of your webapp... then you specified that you wanted the url /test/Testme to map to the servlet, so...

Hope that helps,
