Hi,

My RAP application (1.4.2, 1.5-RC3) is deployed as war onto a JBoss AS 5.1.2.ER2. The AS ships with a custom file protocol url handler [1] that essentially performs the following operation in order to open a connection to a file url:

this.file = new File(url.toURI());

When a resource is requested, e.g the favicon, I receive the following exception on the console:

ERROR [[equinoxbridgeservlet]] Servlet.service() for servlet equinoxbridgeservlet threw exception
java.lang.IllegalArgumentException: URI is not hierarchical
	at java.io.File.<init>(File.java:363)
	at org.jboss.net.protocol.file.FileURLConnection.<init>(FileURLConnection.java:62)
	at org.jboss.net.protocol.file.Handler.openConnection(Handler.java:40)
	at java.net.URL.openConnection(URL.java:945)
	at org.eclipse.equinox.http.servlet.internal.ResourceServlet$1.run(ResourceServlet.java:63)
	at java.security.AccessController.doPrivileged(Native Method)
	at org.eclipse.equinox.http.servlet.internal.ResourceServlet.writeResource(ResourceServlet.java:60)
	at org.eclipse.equinox.http.servlet.internal.ResourceServlet.service(ResourceServlet.java:50)
        ... and more ...

I tracked the problem down to org.eclipse.rap.rwt.osgi.internal.HttpContextWrapper#getResource(String) which seems to generate a wrong resource URL, e.g file:C:/path/to/resource/favicon.png instead of file:/C:/path/to/resource/favicon.png.

File file = new File( name );
if( file.exists() && !file.isDirectory() ) {
    result = new URL( "file", "", name );
}

Is this a bug that has to fixed in RAP?

Thanks for any advise,
Thomas

Hi Thomas,

this sounds like a bug. I guess the URL should be created using
File.toURI().toURL().

Could you please report it in our bugzilla [1]?

Thanks,
Ralf
