RE: Working Directory
This code actually works for me.
getClass().getResourceAsStream(Configuration.xml);
I did dump the Configuration.xml file into the same directory where this
code exists and jar'ed them all up.
com/blort/packagename/Configuration.class
com/blort/packagename/Configuration.xml
You can start this simple and then get fancy.

Carig,
I tried this it does not work. I can't get the stream.
I have a property file in the classes directory- where
I all my classes are. My code is:
MyClass thisInstance = new MyClass();
InputStream stream =
thisInstance.getClass().getResourceAsStream(propFile);
if ( stream != null) {
props.load(stream);
stream.close();
}else System.out.println(The stream null);
Thanks
Sanjay

Thanks Mark Craig.
My situation is slightly different. I am trying to
read the property file from a Java class on the
server(not the servlet). I would think there would
be
a way around to do this- else I can work around to
pass a param to the helper class.
Consider using
getClass().getResourceAsStream(myprops.properties)
for
this kind of purpose. This looks for
myprops.properties on your class
path, and loads it from wherever the classes
themselves are found (either
an unpacked directory or a JAR file).
Thanks
Sanjay

I place my properties files in the WEB-INF
directory and do the following to
find them -
String webInfFolder =
getServletContext().getRealPath(/WEB-INF)
This only works if the app is run from an
unpacked
directory, which is not
guaranteed to be portable (not every server
supports
running this way).
The best way to read a properties file is to put
it
in the WEB-INF
subdirectory and use something like:
Properties props = new Properties();
InputStream stream =
getServletContext().getResourceAsStream(/WEB-INF/myprops.prop
erties);
props.load(stream);
stream.close();
which is guaranteed to be portable to any
server.

I am trying to read a properties file from my
servlet.
It always comes back saying file not found. I
have
tried placing the file in
classes/web-inf/context-path. Ideally I would
like
to
lace it in my classes directory- How do I
achieve
it.
Thanks

RE: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error -HELP-ME-PLEASE
So it executed the Servlet Login2 as evidence in the stacktrace
root cause
java.lang.NoClassDefFoundError
at Login2.doGet(Login2.java:51)
at
javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
... and it got all the way to line 51. It looks like there are other
classes from this jar package that are being invoked. If they are being
invoked with no exception then the jar file is found. But the class at line
51 is not found. My line counting isn't working so you need to point to the
source code line 51. Also assuming your classes are like this:
com.sap.mw.jco.JCO.Repository and the jco.jar file is in your WEB-INF/lib
directory.

RE: Properties files.
Had a similar problem. This code seems to work in a servlet (more comment
after):
--
PrintWriter out = null;
ServletContext servletContext = getServletContext();
try
{
out = response.getWriter();
}
catch ( IOException ioe)
{
return;
}
InputStream inStream = servletContext.getResourceAsStream( /blotto
);
BufferedReader in
= new BufferedReader(new InputStreamReader( inStream ) );
try
{
for(String line = ; (line = in.readLine()) != null; )
{
out.print(line);
out.flush();
}
}
catch ( IOException ioe ) {}
---
The text file 'blotto' is in directory context. That is, the name of your
app, the directory below webapps but above WEB-INF.

I load application property files off the classpath and was
able to load
property files from mywebapp/WEB-INF/classes directory.
Had a little
trouble
with the log4j.properties, had to place that file in
common/classes (may
have
to do with where log4j.jar is located).
Hope this helps.

Hi all,
I was trying to migrating an existing application to

a lot of properties files and just specified the

we can call

Thanks a lot.
