问题:

Basically I am trying to create a simple Hello World program using Rational Software Architect. To create the server I use Tomcat and Jersey. I found that when I create the server without putting the jersey jar files into WEB-INF/lib but rather I create a custom user library with all the jar files, Tomcat will compile fine but the url will not load the "Hello World" text, just a 404 error. I simple do http://localhost:8080/project name/rest/class path name and nothing will come up. I think its because I don't have the jersey files in WEB-INF/lib but when I put the jersey jar files in that folder and try to run the tomcat server, i get a "Server Tomcat v7.0 Server at localhost failed to start." error.

Please help me out and thanks in advance.

回答1:

The unsupported class version error suggests that you are using a newer version of jersey than is supported by your tomcat installation. Most likely it is because of jre version mismatch - the jersey library you are using requires a newer jre but you have an older version

I finally got it. Thanks Sasikanth you were right about my error. The jre must match for apache, your project, and Jersey. The newest Jersey uses jre7 so when you install apache, use jre7 as the build path. Also my Rational project was defaulted to java 1.6 not 1.7. So you have to manually create a build path to jre7. This video teaches you how to do that (just go to java build path in properties of your project, double click jre system library, click installed jres, then add a new path to your jre directory). To find the jre directory just look up java on the start menu, click the java tab, then click view. This made my project build path jre7, tomcat should already be jre7 from the install, and jersey is jre7 as well so everything will match and your server will run correctly.
