I've got:
jersey bundle 1.0.3
grizzly-servlet-webserver 1.9.15a
(also, activation, commons lang, commons logging, jaxb api, jaxb impl,
jsr311 api)
If I follow the straight forward approach from the HelloWorld example,
everything works fine when running inside Eclipse (JDK 1.5.0_16).
However, once i export a jar and run it from a command line (either on
OS X JDK 1.5.0_16 or OpenSolaris JDK 1.6.0_06) the Grizzly web server
starts up, but once I make a web request and Jersey attempts to
initialize, it is failing to locate my HelloWorldResource class
(again, this works when run from inside Eclipse).
Everything (meaning both of my classes) are in jar, classpath is all
setup, etc etc...
There is no special run configuration setup in eclipse, just a basic
Run As > Java Application invocation, which is simply running my main
method with the classpath setup with my libs.
What could possibly be different between running from within Eclipse
and the command line that would only change the way that Jersey is
attempting/failing to locate my resource classes? Here are my two
test classes...
Note that I've tried configuring the grizzly web server two different
ways labeled with "Method 1" and "Method 2", both work from within
Eclipse, both fail the same way when run from the command line
(Grizzly starts up, but Jersey fails to find Resource classes when a
web request is made)
After generating my jar (jersey-grizzly.jar), it is run like this:
java -cp .:activation-1.1.1.jar:asm-3.1.jar:commons-lang-2.4.jar:commons-logging-1.1.1.jar:grizzly-servlet-webserver-1.9.15a.jar:jaxb-api-2.1.jar:jaxb-impl-2.1.11.jar:jersey-bundle-1.0.3.jar:jersey-grizzly.jar:jsr311-api-1.0.jar:junit-4.6.jar:log4j-1.2.15.jar
