RE: resolving relative paths to servet webapp/myapp directory

[Mazza, Glen R., ,CPMS]

Thanks to both--I implemented Mike's solution (also placed the stylesheet
more properly under the web-inf directory.)  It worked fine.
(ServletContext.getResourceAsStream() is also a good solution--thanks.)

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");

resolving relative paths to servet webapp/myapp directory

[Mazza, Glen R., ,CPMS]

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

placement of XML & XSL files within a Struts webapp

[Mazza, Glen R., ,CPMS]

Hello,

Should the XML and XSLT files needed by a web application ordinarily be kept
under web\Web-inf?  (or should they be in web\stylesheets or web\include?)
Assuming two types of files:

1.)  XML lookup data for access by various Action classes and/or JSP pages.
2.)  XSL stylesheets for transforming XML data into HTML and/or PDF.

What's a "good practice" on where they should be stored?

Thanks,
Glen

Commons-logging and JDK 1.4 Logger

[Mazza, Glen R., ,CPMS]

Hello,

I am thinking of using the JDK 1.4 Logging API directly within some of my
web application classes.  Of course, Struts uses commons-logging for its
"internal" messages, so I still need to configure commons-logging to use the
JDK 1.4 Logging.

I am interested in using the same output logging file for both types of
messages:  those I explicitly call via JDK 1.4 Logging, and those messages
written by Struts via commons-logging.  Can I have them append to the *same*
output log file without concern for them overwriting each other's messages?

Thanks,
Glen
