RE: [Jersey] Getting nuts with hangs in Client API

Naresh,

 

I doubt that it is a bug in Windows XP, because it worked well on this
machine until I updated to the latest version of JDK, Jersey and Grizzly. We
tested today on different machines and all of them had the same problem. So
I am pretty sure that it is a bug in Jersey (can you tell me what the bug in
Windows shall be like.? Windows not being able to deal with drive letters
anymore, after 20 years of their existence? I doubt that.). BTW, all the
time in the past 10 years of experience with Java, each other time some Java
programmers said that "it must be a Windows bug" and in the end it was not.
But maybe this time it is. ;-)

 

Regards

Markus

Paul,

 

thank you for your tips and have nice holidays! Just came back from a great
short trip to Vienna, so if you don't know where to go to. ;-)

 

 

:-)

 





The idea with a 10 minutes sleep didn't help. :-(

 

Changing to Grizzly works well (but one really must give the package to scan
or Jersey will tell you that
"C:\C:\jersey-archive-1.0.3.1\lib\jsr311-api-1.0.jar, is not a jar file")!
:-)

 

 

Ug, that looks like a silly windows bug. We will investigate.

I tried running a simple application on Windows Vista, and it did run just
fine.
Here's an extract of what I see upon running the app:

    And here's an extract from the code which creates the SelectorThread:

...
SelectorThread st = GrizzlyServerFactory.create(

So I assume that there is a bug in the http server used internally by
Jersey, and there is a bug in Jersey's ClassPath scanner (it seems to add
another C:\ to each JAR if not giving a package to scan).

 

For my presentation, this should work. But maybe you like to have a look
into the the above items after your holidays? :-)

 

OK.

 

I have wasted way too much time with the LW HTTP server and its issues! In
my experience it is not stable on windows. I can only suggest logging an
issue against the JDK.

 

Paul.
