resolving relative paths to servet webapp/myapp directory
Hello,
I'm doing an XML->PDF XSLT transformation using a XSL stylesheet.
Programmatically, within my Action class, I refer to the stylesheet needed
by using a relative path, with the goal of it being relative to my appname
directory off of the servlet "webapps" directory:
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new
StreamSource("stylesheets\\mystylesheet.xsl"));
..
Problem is, Struts appears to be resolving relative paths from my project
working directory, *not* relative to the "appname" from the webapps
directory in Tomcat.
To confirm this, removing the xsl stylesheet from my working directory
returned this error when I ran the app in Tomcat:
java.io.FileNotFoundException:
D:\myworkingdir\myapp\stylesheets\mystylesheet.xsl
and not this error:
java.io.FileNotFoundException:
D:\tomcat4.1\webapps\myapp\stylesheets\mystylesheet.xsl
How do I specify filenames in Struts so they will be resolved relative to
the webapps\myapp directory (whatever I name "myapp" to be), and not my
(deleteable) working directory?
Thanks,
Glen

I tend to use ClassLoader.getResource or ClassLoader.getResourceAsStream to load
resources. The constraint, obviously, is that the class loader must be able to
access the resources. Generally, this means placing resources under
WEB-INF/classes or in JAR files in WEB-INF/lib. If you don't care about
depending on the Servlet API, try ServletContext.getResource or
ServletContext.getResourceAsStream. In your particular case, you'd use:
InputStream in = context.getResourceAsStream("/stylesheets/mystylesheet.xsl");

we do something similar but we use the WEB-INF directory as the starting
point and all works fine
lets say we are looking for "XML/extraction-map-classday.xml"
the following code achieves this ...
public final class HomePageAction extends Action
...
...
String xmlURI =
this.getServlet().getServletContext().getRealPath("/WEB-INF/XML/extraction-m
ap-classday.xml");
Therefore the "RealPath" to extraction-map-classday.xml = the value in
xmlURI
if you had "stylesheets\mystylesheet.xsl" under the WEB-INF directory maybe
you could follow or approach
i know it works for us but maybe we just got lucky !!!
