[BUG T322] Bug in getServletContext().getResource() for relative URLs

[Stevenson, Chris (SSABSA)]

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)
