Simple Test Servlet not working, when hosted on GoDaddy server,Why?_问答_开发者

I was trying to test servlet by hosting it on shared hosting by GoDaddy server. I am compiling the code using Java SDK 5_0_22(The SDK version of GoDaddy server). I tested same code,folder structure, on LOCAL Tomcat5.0.27(The server verision of Godaddy).

But I am able to run JSP file; this proves that my account is JAVA enabled.Please help. P.S. Every time am getting 404 error.index.jsp is working fine.

FolderStructure:-

WebApplication--|

|-META-INF

|-WEB-IN开发者_JS百科F---|

|-classes--|--test.class

|-web.xml

Running packageless servlets doesn't work in all circumstances. Classes in the default package are by specification invisible/unimportable to classes in a real package. As far as I know, only certain Tomcat + JVM + Windows version combinations allows for that. But you should never rely on that environmental dependency. You should always put your servlets (preferably also all other Java classes!) in a package.

package com.example;

// ...

public class TestServlet extends HttpServlet {

    // ...

}

The compiled class should end up in /WEB-INF/classes/com/example/TestServlet.class and the servlet mapping should be updated as follows:

<servlet>
    <servlet-name>testServlet</servlet-name>
    <servlet-class>com.example.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>testServlet</servlet-name>
    <url-pattern>/test</url-pattern>
</servlet-mapping>

Also note that I fixed your classname to start with uppercase conform Java naming conventions.

Unrelated to the concrete problem, I know that you're just beginning with servlets and that your servlet is just a dummy test example. I would only stress that emitting HTML inside a servlet that way is considered a bad practice. JSPs should be used for that. See also our servlet wiki page.

GoDaddy does not support java on shared hosting space websites it seems:

Maybe with a dedicated server you can do that.
