Re[4]: [JBoss-dev] URLConnection and opened files
I'm a bit confused. I wrote a simple standalone test.
- main
public static void main(String[] args) throws Exception
{
// set handler pkgs
System.out.println(java.protocol.handler.pkgs: +
System.getProperty(java.protocol.handler.pkgs));
URL url = new URL(file, null, args[0]);
System.out.println(url: + url);
URLConnection urlCon = url.openConnection();
System.out.println(connection class: + urlCon.getClass().getName());
url = new URL(other, null, args[0]);
System.out.println(url: + url);
urlCon = url.openConnection();
System.out.println(connection class: + urlCon.getClass().getName());
}
- run
java -Djava.protocol.handler.pkgs=org.avoka.test.files.protocol -classpath %cp%
org.avoka.test.files.FilesTest build.xml
- output
java.protocol.handler.pkgs: org.avoka.test.files.protocol
url: file:build.xml
connection class: sun.net.www.protocol.file.FileURLConnection
url: other:build.xml
connection class: org.avoka.test.files.protocol.other.OtherURLConnection
I do have org.avoka.test.files.protocol.file.Handler and
org.avoka.test.files.protocol.file.FileURLConnection on the classpath.
My file.Handler isn't called. Am I missing something?
This same thing happens with JBoss-3.2 and HEAD but not JBoss-3.0 (my
3.0 is not up to date).
JDK1.3.1_05, J2SDK1.4.0
Win2K
Thanks,
alex

Re: Re[4]: [JBoss-dev] URLConnection and opened files
Oh, I now remeber looking at this but I can't remember the context. There
is a cache of handlers as the URL level. If the file protocol is referenced
before the custom JBoss handler is available then the default Sun one will
be used. Is there a difference between 3.0 and 3.2 with regard to when the
custom protocol handlers are installed? I'll check later today.

Re[4]: [JBoss-dev] URLConnection and opened files
I meet it in JBoss-3.2 and HEAD. I am afraid if I update JBoss-3.0
it'll get infected too. I'll try to figure it out.

Thanks for pointing to this, but I think the problem is not there.
I suspect the classes are somehow not getting to the classpath.
I'm running jdk1.3.1_05. Note, earlier I ran JBoss w/o these problems
on this same VM.
Please, let me know whether it's only me watching it.
Thanks,
alex
