It is not a bug, "ServletContext.getRealPath("") never return a real path on
OSGI container.
For Equinox framework, use the following code fragment:
import org.eclipse.core.runtime. FileLocator;
...
ServletContext context = request.getSession().getServletContext();
URL url = context.getResource("/");
String realPath = FileLocator.toFileURL(url).getPath();

Subject: unable to getRealPath for servlet context
I found the following Jetty bug report:
http://jira.codehaus.org/browse/JETTY-675
<http://jira.codehaus.org/browse/JETTY-675>
User states the following:
"ServletContext.getRealPath("") returns null instead of returning the root
dir of the webapp"
I am able to reproduce this behavior in my WAR bundle with MANIFEST.MF (WAB
(WebApplication Bundle)) deployment to Karaf 3.0.0. The version of Jetty is
the following:
karaf@root()> feature:list | grep jetty
cxf-http-jetty | 3.0.0-milestone2 | x |
cxf-3.0.0-milestone2 |
jetty | 8.1.9.v20130131 | x |
standard-3.0.0 |
pax-jetty | 8.1.14.v20131031 | x |
org.ops4j.pax.web-3.0.5 | Provide Jetty engine support
I have tried ServletContext.getRealPath("");
I have also tried ServletContext.getRealPath("/");
Both code lines return null.
Is this expected for this version of Karaf/Jetty? If yes, how can I
determine the real path.
Our scenario involves a properties file that may be installed in
karaf/config/foo directory. We don't want to load/read the file from inside
the WAR (e.g. WEB-INF) b/c the customer may need to change the file.
