Question

I’m using tomcat7 server for my project. Today i combined some html pages to a directory called sp for managing purpose. When i enter the http://localhost:8080/skypark/sp/upload.htmladdress, upload page in sp directory will displays.
But when i try to submit the contents it shows

HTTP Status 404 – /skypark/sp/FileUploadServlet

description: The requested resource is not available.

My directory structure is :

I don’t know why it was showing this error

the servlet mapping for FileUploadServlet is:

<servlet id="spU">
<display-name>FileUploadServlet</display-name>
<servlet-name>FileUploadServlet</servlet-name>
<servlet-class>skypark.FileUploadServlet</servlet-class>
</servlet>
<servlet-mapping id="spUm">
<servlet-name>FileUploadServlet</servlet-name>
<url-pattern>/FileUploadServlet</url-pattern>
</servlet-mapping>

Before adding to sp directory upload.html worked well, files where uploaded normally. Please anyone tell me why it was showing this error…thanks………

Answer 1

Use

<url-pattern>/sp/FileUploadServlet</url-pattern>

The pattern must be absolute starting your webapp context path. So, if your webapp is skypark, it must start from there.
