I haven't dealt with TC 4 in a long time. I would think it's the
difference in how the user is forwarded to the resource. An internal
forward leaves the browser to compute relative paths based on the
original request URI while an external forward offers the browser a new
request URI to compute relative paths against. Best practice would be
to get the context path and then define the image source as an absolute
path from the server root:
Assuming a webapp designed to servlet 2.4/jsp 1.2 spec (tomcat 5.0/5.5),
that would be <img src="${pageContext.request.contextPath}/logo.gif"/>
For a servlet 2.3/jsp1.1 spec (tomcat 4), that might be <img
src="<%=request.getContextPath()%>/welcome/logo.gif" />
This method leaves the flexibility to have the same webapp in different
context while making sure the resource path is always computed correctly
regardless of forward method.
