OSGi and URL.openConnection
I am total novice with OSGi and this is my first experiment. I turned my
application into set of bundles and it was successful except for one
issue. I have piece of code where I do something like that
url.openConnection (proxy); and here I've got
UnsupportedOperationException. Apparently something is getting messed up
in between OSGi and java.protocol.handler.pkgs system property. I made
several unsuccessful attempts to fix it but eventually only way I
managed to make it work is by setting "felix.service.urlhandlers" to
"false". I think this is a wrong way to do it. What would be the right
way and also what functionality did I loose by setting this property to
"false"

RE: OSGi and URL.openConnection
Posted by Os...@emc.com.
Richard,
There is nothing specific in what I am doing. The protocol is HTTP. The
only thing is that I use proxy i.e. call looks like url.openConnection
(proxy). The exception comes from
java.net.URLStreamHandler.openConnection(URLStreamHandler.java:80) and I
use Sun JVM. Normally handler for open connection comes from
sun.net.www.protocol so either urlhandler bundle redefines system
property java.protocol.handler.pkgs or it sets its own
URLStreamHandlerFactory. I didn't look into source code yet and by the
way can I?
Please let me know what additional information do you want me to
provide.
Regards,
Alex

We probably need more details about what is exactly going on, but you
are right, it shouldn't be necessary to disable it.
What does the URL look like for which you are doing url.openConnection()
?
Are you defining your own stream handler for a custom protocol?
