I installed GeoServer 2.1 RC1. It installed successfully, but when i click on WFS in services category, i got the following message.
Oops, something went wrong... Sorry, something unexpected happened on the server.
Here's an error report you can include in a JIRA bug report about this issue:
org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor public org.geoserver.wfs.web.WFSAdminPage() at org.apache.wicket.session.DefaultPageFactory.createPage(DefaultPageFactory.java:212) at org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:57) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.newPage(BookmarkablePageRequestTarget.java:298) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.getPage(BookmarkablePageRequestTarget.java:320) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.processEvents(BookmarkablePageRequestTarget.java:234) at org.apache.wicket.request.AbstractRequestCycleProcessor.processEvents(AbstractRequestCycleProcessor.java:92) at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1250)
What is wrong ? How can i fix this problem ?
