servlet mapping in tomcat

Question

Sorry about the vague title but I have a servlet with the following mapping in web.xml

<servlet>
  <servlet-name>SomeServlet</servlet-name>
  <servlet-class>SomePackage.SomeServlet</servlet-class>
</servlet>  

<servlet-mapping>
    <servlet-name>SomeServlet</servlet-name>
    <url-pattern>/servlet/SomeServlet</url-pattern>
</servlet-mapping> 

that opens a html file in a different folder and writes to Response. As a result, the images in that html try to load /servlet/images/someimage.png instead of /images/someimage.png

I know that the image reference in the html is relative and hence it trying to go from the servlet path but I can't change the html page or the servlet code. Is there any why to fix this from the configuration files?

Thanks

Answer 1

In You HTML file use the context path..

<img src ="/CONTEXT/images/someimage.png"/>

e.g

<img src ="/StackOverOverflow/images/someimage.png"/>

Sorry I didn't notice that you can't change the HTML.

How about creating a filter which will filter out the images and will forward the call to the servlet if it matches your servlet path? Did you try this?

Answer 2

Map the servlet to /SomeServlet.

Or create a servlet mapped to /servlet/images/*.jpg that forwards to /images/Xxx.jpg, where Xxx is what matched the wildcard.

What kind of environment are you working in, where you can't change anything?
