Tuscany on Glassfish
Had some difficulty getting Tuscany 2.0 Beta 3 running on Glassfish 3.1.2 using Wink for the REST bindings. I was hitting an issue it seemed others were getting with Apache Wink throwing the exception below.
java.lang.NullPointerException
at org.apache.wink.common.internal.http.Accept.valueOf(Accept.java:139)
at org.apache.wink.server.internal.contexts.HttpHeadersImpl.getAcceptHeader(HttpHeadersImpl.java:151)
at org.apache.wink.server.internal.contexts.HttpHeadersImpl.getAcceptableMediaTypes(HttpHeadersImpl.java:105)
I'm new to Glassfish but just wanted to leave my workaround here since it seems no one had an answer for it. You need to place Wink and its dependencies (i.e. slf4j) in your glassfish "libs" directory (i.e. \glassfish3\glassfish\lib). If you don't the constructor of org.apache.wink.common.internal.runtime.RuntimeDelegateImpl never gets hit and along with it the header delegates never init.
Someone no doubt has a better solution but thought I'd pass it on.

In couple of app servers (e.g. websphere and I believe geronimo), we
have to configure to use the webapp classloader first. Based on your
workaround and [1] this might seem to be the same problem, And [2]
seems to explain how to turn app classload priority under
"Application-Specific Class Loading" section. Let us know if that
helps a bit... so we can document for others.
Thanks

Yes I did include Wink and Tuscany in the WAR to start with. I was migrating from the embedded Jetty implementation to Glassfish so had something to compare against. Started debugging into Wink and from what I could tell it was a classloader issue. Again probably my inexperience with glassfish but hopefully it will get someone else over the hump.

Did you use Tuscany as part of the WAR for your web application when you hit the NPE? I assume you need to make sure the wink jars are available withTuscany jars.
Thanks,
