Yes, please use ServletContext.getResourceAsStream.

 both of these are well documented in the servlet spec.

And in the Servlet API itself if you don't want to dig into the spec
just to read the javadoc.

Re: loading properties file from WEB-INF instead of WEB-INF/classes

 getPropsFromWebINF works so long as the properties file is within the
 package of
 the class (/.  However, I'd like to put the properties file under WEB-INF:



public void getPropsFromWebINF() throws IOException {
Properties p = new Properties();
InputStream is;
is = getClass().getResourceAsStream(sqljdbc4.properties);
p.load(is);
log(p.toString());
}


Class.getResourceAsStream() will delegate to the classloader to find the
resource (searches the classpath) , see
http://java.sun.com/javase/6/docs/api/java/lang/Class.html#getResourceAsStream(java.lang.String)
The tomcat site has an excellent description of Tomcat's classloading :
http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html , this
should bring you to the conclusion that the above won't work.
You should put your sqljdbc4.properties file in WEB-INF/classes, or in
WEB-INF/lib if packaged in a jar file.
If you reference it from your application, make sure you prepend a / (or
it will search in your servlet's package) .



I've seen mention of using:

 System.getenv(APP_PROPERTIES);

 in conjunction with a context (context.xml under META-INF) along the lines
 of:

 ?xml version=1.0 encoding=UTF-8?
 Context antiJARLocking=true path=/A00720398sat
Environment name=APP_PROPERTIES
 description=The APP Properties File override=false
 type=java.lang.String
 value=/WEB-INF/app.properties /
 /Context


 however, I'm not able to get the environment, I just get a null value.


can you be a bit more specific where you get a null value (show some lines
of code)...
although the above won't bring you to the content of the property file, you
only have defined a key/value pair.

Harry


 What's the correct, and simple, idiom?  (Staying away from jndi and dbcp
 for
 now, and, oddly enough, servlets in this case.)



 Actually, I suppose in a sense it's in WEB-INF:

 however, I'd like to move it from WEB-INF/classes up to just WEB-INF.

props file can be placed in src package and then placed along with classes

Re: loading properties file from WEB-INF instead of WEB-INF/classes

2010-04-18 Thread David Smith 
An alternative exists in the ServletContext class --

ServletContext.getResource( path ) takes path as relative to the current
webapp and returns a URL for opening the resource or null if the
resource was not found.

also there is --

ServletContext.getResourceAsStream( path ) takes a path as relative to
the current webapp and returns an i/o stream for reading the file.

For example, using this within a servlet:

try {
java.io.InputStream res_stream =
this.getServletContext().getResourceAsStream('/WEB-INF/my-config.ini') ;
// read the data
} catch (java.io.IOException ioe) {
// handle the problem
}

both of these are well documented in the servlet spec.

Not quite sure what you mean by this, but assuming you mean that there 
is a link to country-flag.gif, and depending on the user's origin, you 
want to send back the appropriate one, in my simple mind I would create 
property files with the appropriate translation to the real thing, and 
use them in my application to return the appropriate image (or redirect 
to it).
