RE: NewB/Default Servlet:Can't find .gif
Hello List... Hallo Newbie ;-) NEWBIE: I want to generate the welcome page for my domain so I mapped a test servlet to / in the web.xml for my context. PROBLEM: A test.gif image is not rendered by the servlet - as it appears the path is not found. Are you trying to return html including an image link (such as img src=test.gif) or trying to stream an image via the servlet? If the latter, then jsp is the wrong tool - it is text only. If not, read on: *** Can you send us the location and output of your jsp page and the location of your gif please? *** It sounds like a simple problem. OBSERVED: If I map the servlet instead to /intro then the test.gif is rendered ok. TRIED: Using various path combinations/test.gif, test.gif etc - no result. NOTE: I've read some postings advising locating files should be done as in InputStream [getResourceAsStream()]. Is it applicable in this case when all I want is a simple out.println( img src=\/test.gif ... etc )? Oh, then you are trying to do it right! Good.

I'm confused as to why once I change the servlet-mapping from / to /intro that the .gif is read. So am I ;-) Can you print out the output from either case and send it.

Thanks Justin...
excerpt from web.xml

servlet-name
intro
/servlet-name
servlet-class
intro
/servlet-class
/servlet
servlet-mapping
servlet-nameintro/servlet-name
url-pattern/intro/url-pattern
/servlet-mapping
intro.class is in $CATALINA_HOME/webapps/ap.org/WEB-INF/classes
test.gif in in $CATALINA_HOME/webapps/ap.org/
intro.java
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class intro extends HttpServlet {
public void doGet( HttpServletRequest req, HttpServletResponse res )
throws ServletException, IOException {
res.setContentType(text/html);
PrintWriter out = res.getWriter();
out.println( htmlheadtitlejustatest/title/head );
out.println(img src=\/test.gif\ width=\146\ height=\125\
alt=\TEST\);
out.println( bodyh1Justatest...!/h1/body/html );
}
}
Here I realise I may have misled you:
This page renders ok if I explicitly point to url www.domain.org/intro
^
It fails if I change the url-pattern within the servlet-mapping to / (and access it
with the url www.domain.org/) - the test.gif is no longer found by the server.
Any suggestions? Rgds/j-p.

Can you print out the output from either case and send it.

RE: NewB/Default Servlet:Can't find .gif
Is there a way then, to automatically invoke a servlet by pointing to the url www.mydomain.com (Or am I obliged to use .jsps)? thanks/j-p.

RE: NewB/Default Servlet:Can't find .gif
I don't know of a way to map www.mydomain.com to a servlet without that servlet being the default servlet. The way servlet mapping works, I think this is unavoidable. If your servlet isn't able to be the default servlet, it will have to be invoked indirectly. You could try an index.jsp that forwards to your servlet.
