Guys,

Im new to Servlets JSP's etc.., having some issues with the stuff below.

I have a servlet (just a test one for now) that in its post method just forwards the requester to google ,

response.sendRedirect("http://www.google.com");
return;

The JSP that calls this is has the following

<form method="POST" action="../servlet/servlets.UploadServlet"/>

The web.xml has the following code (I modified after reading some of the postings)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
<display-name>mcaiyzm2 Web Application</display-name>
<description>mcaiyzm2 web application for JRun</description>
- <servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>UploadServlet</servlet-class>
</servlet>
- <servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/servlets</url-pattern>
</servlet-mapping>
</web-app>

The servlet is stored in the directory structure /web-inf/classes/servlets

When i click the button, in the url, it says "The file that you requested could not be found on this server. "

What have I done wrong?

All the help that u can give me will be appreciated.

Thanks in advance
Zein

Bug 1, servlet deployment setup, it should be

<servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>servlets.UploadServlet</servlet-class>
</servlet>

Bug 2, url mapping

<form method="POST" action="../servlet/servlets.UploadServlet"/>

does not match

<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/servlets</url-pattern>
</servlet-mapping>

Danny,

Thanks for the above, still doesnt work. Says HTTP 404 - File not found.

<servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>servlets.UploadServlet</servlet-class>
</servlet>

Web.xml has been modified as above. Also post action has been modified to look like

<form method="POST" action="servlets.UploadServlet"/>

with the corresponding web.xml like below

<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/servlets</url-pattern>
</servlet-mapping>

Any ideas?

Regards
Zein

You mapped the servlet to the url, /servlets, and tried to invoke 'servlets.UploadServlet' by the form action. That's why you got the status code 404.

Try again with <form method="POST" action="/servlets"/>.

Well guys,

This issue is still out standing, now the error is

HTTP 405 - Resource not allowed
Internet Information Services

The jsp post reads
<form method="POST" action="/servlets"/>

The web.xml is as follows

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
<display-name>mcaiyzm2 Web Application</display-name>
<description>mcaiyzm2 web application for JRun</description>
- <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
- <servlet>
- <init-param>
<param-name>browseDirs</param-name>
<param-value>false</param-value>
</init-param>
<servlet-name>FileServlet</servlet-name>
<servlet-class>jrun.servlet.file.FileServlet</servlet-class>
<description>This servlet may override a corresponding FileServlet in SERVER-INF/default-web.xml.If removed, the servlet in default-web.xml will be used.</description>
</servlet>
<distributable>false</distributable>
- <servlet>
<!-- Above this is default -->
<servlet-name>UploadServlet</servlet-name>
<servlet-class>servlets.UploadServlet</servlet-class>
</servlet>
- <servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/servlets</url-pattern>
</servlet-mapping>
</web-app>

Directory structure is

WEB-INF\classes\servlets


And the post method is as follow

public void doPost(
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();

out.println("<HTML>");
out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
out.println("<BODY>");
out.println("<BIG>Hello World</BIG>");
out.println("</BODY></HTML>");

}
What have i dont wrong now? Its all correct as far as i can see?!!!

in the web.xwl in the servlet-mapping tag should be

<url-pattern>/servlet/servlets/UploadServlet</url-pattern>

The url in <url-pattern>/servlets</url-pattern> seems like causing the problem. '/servlet' and '/servlets' might be used by the servlet container to dynamically invoke servlets with no mapping information when the user sends a request by calling /servlet/packagename.SomeServlet.

So, why don't you try with different url-pattern like

<url-pattern>/UploadFile/*</url-pattern>

and use <form method="POST" action="/UploadFile"> in the jsp.

This issue is still out standing, now the error is

HTTP 405 - Resource not allowed
Internet Information Services


Looks like it's from IIS web server. What servlet container are you using?

Well ok the problem is completely solved now.

instead of using ../servlet, I had to use ./servlet [not one dot]. Reason is, my jsp's etc.. are not in a folder, they just lie in the root directory.

Thanks for the help guys, really appreciated
