hi all.
i am currently working with java-based blogging engine.
it's presentation layer is based on struts framework.

to make urls look tidy (www.myblog.com/entry/Test-Entry)
i've been trying to use RequestDispatcher object to forward the
incoming tidy url to our blog engine's native url (such as
www.myblog.com/blog/entry/view.do?logTitle=Test-Entry).

but it does not work at all.
system yields the log below.

- Invalid path /blog/entry/view was requested

i don't have any idea.
could anybody help me out?
thanks.

joshua song.

sorry i forgot something.
i used this two lines of simple code:

RequestDispatcher rq = request.getRequestDispatcher("/blog/entry/
view.do?logTitle=Test-Entry");
rq.forward(request, response);

When you get the RD from request it cannot step outside the current context
root. You have to get the ServletContext of the other context root, then call
ServletContext.getRequestDispatcher(java.lang.String) on it.
