Re: [Rife-users] Problem with online user guide's "Get Started" part

[Emmanuel Okyere]

That is also a TODO for me now to change the "Getting Started" page to just point to Jumpstart :)

Cheers,

Allen,

You are having classpath issues and nothing to do with the hello world or rife implementation. I don't think you need to move anything around for the hello world experience with rife... and since you are just starting with the framework, it's probably much better to play around with the default settings, at least until you have a fair idea of what's going on.

Just download jumpstart (and i'm assuming eclipse is your IDE of choice), import the project into your workspace, and click the launcher (i think it's Run WebUI or so) to start it. It will compile and start Jetty (default app server that comes with jumpstart).

You can open the "Run WebUI.launch" file and/or look at the included ant build file to see how the classpath is setup... and if you have any more problems, we'll be here to provide some guidance.

Thanks.

 

First, I've found out the problem is that in the rife-examples-1.4-jdk15.zip I had downloaded, there are no .class files in the "/WEB-INF/classes/implementations" folder but .java files. I was thinking there should be .class files so I hadn't check that. Just now, I complied the .java files and put .class files in the folder, something happened at last, but not the "HelloWorld" I expected, but exceptions. I think this is another problem. The detail expcetion information is as follows:

Hi Allen,

can you give us more information about what doesn't work? It's
difficult to help you without additional information.
