GWT Error problems

[Ross McKinnon]

Hi there,

Ive been reworking my GWT app and an error has occurred. I have no
idea what has caused it and the error messages aren't very useful.

Has anyone came across this before?

Thanks,
Ross

jetty couldn't find com.mckinnon.ross.server.DataTableServiceImpl

Did you also rework web.xml?

[Ross McKinnon]

No I have not altered web.xml.

the servlet-class tags match where the classes are located.

Thanks

But may be you renamed com.mckinnon.ross.server.DataTableServiceImpl and didn't modify web.xml to reflect that?

It's strange that jetty does not complain about all other servlets except this one...
