Subject RE: Path problem
Date Mon, 30 Oct 2000 08:47:15 GMT
Hi Shankar
I don't know JSP at all but your include problem is a common. If JSP
includes work like most other environments, what is actually happening is
that your included file is replacing your include statement. So if you refer
to "images/image1.gif" in top.jsp, that same path is going to be used in
Is there an equivalent in jsp to $DOCUMENT_ROOT in php? This gives you the
full path to the current file, that way your full path is calculated
dynamically which will work for your production enviroment. 
Another option is to set the full path some where, database, include file,
application session and append it to your includes. This variable is then a
setting that must be changed when you move to production. etc.
Hope that was clear.

Subject: Path problem

Sorry for a long mail. Please help me with this. 
Our company has lot of small teams developing websites. we use a central jsp
engine(tomcat) for development. In order to refer to pages we use relative
paths and it is causing problems. this is the situation.
This is our file structure.
top.jsp is used by all the pages thru out the project. 
index.jsp includes top.jsp as <%@ include file="Top.jsp" %>
and Top.jsp has reference to image1.gif as <img width=600 height=25
mission.jsp includes top.jsp as  <%@ include file="Top.jsp" %>
but this causes a problem - the image1.gif gets referenced in mission.jsp as

<img width=600 height=25 src="images/image1.gif"> and thats a wrong path and
the image is not shown.

Work around:
So we decided to use absolute paths. now that causes an entirely different

Problem with workaround:
When we refer to other pages with absolute paths, we have to specify the
whole "/projects/proj1/....."(c:\programs\jrun\data is the root), but this
is not the path that will be in production.
Using virtual directories is also ruled out as we have to mention the
virtual directory name in the file path.
Does anybody have a different approach we can use.
Solution being considered:
One of things we were thinking is modifying tomcat code to replace the path
of all files to the absolute path at runtime.
