Unconditional session id with setForward()
Hi!
I would like to prevent creating sessions in my webapp which is based on
Struts and Velocity.
There is the StrutsLinkTool.setForward() method. Is it possible to prevent
the setForward() call from creating session ids??
I've read in a post at the velocity developer list that a session id is
created unconditionally in the setForward() call so maybe it is is not
possible..

Here is the link:
http://www.mail-archive.com/velocity-dev@jakarta.apache.org/msg07893.html
The relevant lines are quoted here:

...
The difference from the HttpServletResponse counterpart is that this one
puts the session id in unconditionally.

hmm. i'm pretty sure that LinkTool/StrutsLinkTool doesn't create session ids.
they also shouldn't create sessions. however, they do always call
response.encodeURL(String), which is supposed to encode the session id into
the URL if sessions are being used but cookies are not supported
see
http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/http/HttpServletResponse.html#encodeURL(java.lang.String)
for more on this.

This is an Oracle Application Server question, not a velocity question.
However, using OAS 10g, Velocity, and struts, here is an example of how I do
it for a ccs file.
<link rel=stylesheet
href="${request.getScheme()}://${request.getServerName()}:${request.getServerPort()}${request.getContextPath()}/img/ebpp.css"
type="text/css">
This assumes that /img is at the same level (ie, main level) in your war
file as /WEB-INF.

Configuration Problem in Oracle9iAs
Posted by Rana Asif Rubbani <ra...@adamsoftintl.com>.
Hi
I'm trying to run velocity in Oracle9iAs and i'm quite new to velocity
world.
The directory structure my application in Oracle9iAs is
all jsp/velocity templates are in
D:/oracle9ias/j2ee/home/applications/doccomply/doccomply/
I'm using a javascript file lets say test.js in a velocity template but when
html is rendered the js file is not picked up and it gives a javascript
error.
e.g. the code for inclusion of javacript is
<script scr="test.js" language="JavaScript"></script>
but when i give absolute url or path in the template like
<script scr="$url/test.js" language="JavaScript"></script>
where url = http://jupiter:7778/doccomply
it works fine...
I'm afraid that when thi s code will be deployed on testing or production
servers the url will change and my code will not work.
Different users access the same application in production using different
URLs.
Please advise that why the script files are not being picked up while in a
template or i have to access them using absolute URLs or paths.
the templates are being picked up fine but not the js files in them.
regards
Rana Asif Rubbani

The general approach to this would be to subclass StrutsLinkTool, change
setForward so that it won't create a session id, and update your toolbox.xml
file to use your new LinkTool.
The "change setForward" step is something you'll have to investigate. It
may require a little work.
