Combining jsp getProperty with HTML EMBED

Question

Hi, Just a quick question, I have a couple of JSP/HTML books and I can't find a way of achieving this;
basically I have a webpage that embeds a VRML file like so
<EMBED SRC="/VRML/stair.WRL"
TYPE="model/vrml"
WIDTH="300"
HEIGHT="300"
VRML_SPLASHSCREEN="TRUE"
VRML_DASHBOARD="TRUE"
VRML_BACKGROUND_COLOR="#0066CC"
CONTEXTMENU="TRUE"
>
This works fine, the problem is that I now have a servlet that dynamically generates the VRML file to be displayed, so I need a way of inserting this variable into the EMBED header, how do I do this?
If it can't be done with JSP etc then how about a JavaScript solution?
Anyway, ive tried a few things and Im out of ideas
Cheers
PS, the current JSP property finder;
<jsp:useBean id="vrmlFileFinder"
     type="legato.VRMLBean"
     scope="request" />
<jsp:getProperty name="vrmlFileFinder" property="fileName" />

Answer 1

There are two issues here
1 - generating the WRL file (from your servlet)
2 - generating the EMBED tag in the HTML/JSP page
These are two different requests to the web server.
1- generating the WRL file:
You say you have a servlet which generates the VRML code?
Does it generate it to file, or output it directly?
If it outputs it directly, just point the src of the tag to be your servlet
ie
<EMBED SRC= "/servlet/VRMLServlet"...
This will invoke your servlet, and return the code to the browser. (ie as long as the servlet sends it a WRL text format, it can't tell the difference)
2 - generating the EMBED tag:
If you want to dynamically choose which file to include, then JSP would do it like this:
<jsp:useBean id="vrmlFileFinder" type="legato.VRMLBean" scope="request" />
<EMBED SRC="<jsp:getProperty name="vrmlFileFinder" property="fileName" />"...
Remember that the JSP code gets executed first, so if the property evaluates to "/VRML/stair.WRL" all the browser will see is
<EMBED SRC="/VRML/stair.WRL" - it doesn't see the JSP code at all.
Hope this helps.
