getContextPath()

Hi,

On my JSP page I make a href call to open another page that
has the hardcoded server name as part of the URL. To remove
the hardcoded reference I am trying
<%=request.getContextPath()%> but this is failing. I get an
error message that the URL is not found. Is there anything
incorrect in using the <%=request.getContextPath()%>.

The code snippet is below.

Harcoded Server reference
---------------------------------
parent.frame_3.document.location.href="http://dbsnaxpws1004:8080/datamanager/tabledata.jsp"

getContextPath()
----------------------
parent.frame_3.document.location.href="<%=request.getContextPath()%>/datamanager/tabledata.jsp"

Any inputs is highly appreciated.

Regards,

Ravi

You can form the complete URL as follows:

<%=request.getScheme()+"://"+request.getServerName()+":"+request. getServerPort()+requ
est.getContextPath()%>/datamanager/tabledata.jsp

Hi Mark,

Thanks for the help.

I get "Object expected ;" JS error when I create the URL as
suggested. However I tried building by getting the
individual parameter values into local JS variables and
concatenate them to one url string which works. I am not
sure why this could happen.

URL String via JS variables
--------------------------------
var js_getscheme = "<%=request.getScheme() %>";
var js_getsrvname = "<%=request.getServerName() %>";
var js_getsrvport = "<%=request.getServerPort() %>";
var js_getcontextpath = "<%=request.getContextPath() %>";
var js_url =
js_getscheme+"://"+js_getsrvname+":" +js_getsrvport+js_ge
tcontextpath+"/tabledata.jsp?dmtarget="

Thanks and regards,

Ravi

You're confusing the use of getContextPath(). It returns that root web
application context. In your case, getContextPath() will return
"/datamanager", not the host name.

I may be wrong but you are most likely going to have to
write out the JavaScript in your jsp code.

<javascript type=text/javascript>
<%
out.println("var js_getscheme='"+request.getScheme()+"';");

%>
</javascript>

I havent my code on hand but I have done similar in the past.

Do you have a web app created? In other words, is datamanager a
webapplication? I am pretty sure I ran this code of yours when we last
talked about it. Wasn't I the one to suggest using getContextPath :)?
