[BUG T322] Bug in getServletContext().getResource() for relative
URLs
Bugzilla is down so I am forced to send this to the list:
Relative URLs from a servlet resource do not work (Tomcat 3.2.2).
I have the following code in a Servlet:
URL propURL = getServletContext().getResource(
"/WEB-INF/connection.properties" )
URL configURL = new URL( url, "config.xml" );
The servlet throws a FileNotFoundException on configURL.getInputStream()
some diagnostic info follows:
Could not load configuration file: file:persist.config.xml
propURL: file:F:\tomcat\tomcat-dev\webapps\ore\WEB-INF\connection.properties
configURL: persist.config.xml
Apache Tomcat/4.0-b5 works perfectly, but its using jndi.
Also, if I do the following:
URL configURL = new URL( url, "config.xml" );
configURL = new URL( configURL.toString() );
it works!
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)
Full Exception is
java.io.FileNotFoundException: persist.config.xml (The system cannot find
the file specified)

Yes, Have a look at this
Bug Id: 4447088
On the Bug Parade at the JDC. I submitted this after trying to use
classloader.getResource() in a servlet. URL doesn't construct a proper
URL string when the constructor you show is used. Works fine on
unix/linux, but windows absolute paths can start with a letter, not a
slash. I'd like to see tomcat use a different constructor so I can rip
out some special code that checks the classloader first!

Posted by Marc Saegesser <ma...@apropos.com>.
According to the spec, the path passed to ServletContext.getResource() must
start with a "/".
