Finding config file.
Hi all,
I have config xml files for my app. Does anyone know how I could find and
load them using a relative path to the class file wanting it instead of the
working directory of the entire app?
Basically, I want to do the same thing that Configuration() does in hibernate.
It looks for either hibernate.properties or hibernate.cfg.xml in the base of
the classpath. It also loads mapping files relative to the cfg file. How to
do that would be nice too.
Currently, I use the relative path to the project in eclipse. I will have to
change that to something else when I deploy it to tomcat. I would like it so
that the paths work no matter where I move the config and class files
(keeping their relative relations in tact).
Thank you,
Vamsi

Vams,
I usually put my xml/config files in the WEB-INF folder. On app
startup I read them in as input streams in my ApplicationServlet
subclass.
Hope this helps,
eric
public class MyAppServlet extends ApplicationServlet {
/**
* @see javax.servlet.Servlet#init(ServletConfig)
*/
public void init(ServletConfig config) throws ServletException {
super.init(config);
InputStream myXmlFile = getResourceAsStream("myXmlFile.xml");
}
protected ServletContext appContext;
protected InputStream getResourceAsStream(String resource) {
return getAppContext().getResourceAsStream("WEB-INF/" + resource);
}
protected URL getResourceURL(String resource) {
URL url;
try {
url = getAppContext().getResource("/WEB-INF/" + resource);
} catch (MalformedURLException mex) {
logObj.warn("Error locating resource.", mex);
return null;
}
return url;
}
/**
* @return
*/
public ServletContext getAppContext() {
return appContext;
}
}

Every class has access to the ClassLoader that was used to load it, so
you can use that to get to your file.
If your class is MyClass,
MyClass.class.getResourceAsStream("config.xml")
should return an InputStream for a config.xml file located in exactly
the same folder as MyClass.
HTH,
Todd
