Problems with GWT 2.4

Question

I compiled the version in svn tagged as gwt2.4rc. Now there are a couple of more libraries than I had the last time. Are the any instructions on which library is needed for what? I tried it with only the standard libraries (servlet, servlet-deps, user) but I get the following error when a requestfactory call is made: java.lang.NoSuchMethodError: com.google.gwt.core.client.impl.WeakMapping.setWeak(Ljava/lang/ Object;Ljava/lang/String;Ljava/lang/Object;) I tried declaring the requestfactory-client and requestfactory-server jars as dependencies, but i doesn't help. I am using maven to manage my dependencies. I would go back to 2.4 beta, but I need the drag&drop features that were introduced later. Does anybody has an idea what could be wrong? or any hints how i can dig deeper into this? I spend a lot of time trying to figure this out but without any success :( Do I need to provide more information?

Answer 1

Are you sure you deployed the 2.4-rc1 gwt-servlet.jar in your war/WEB-INF/lib ? Also, make sure you override the SDK for the gwt-maven-plugin: http://mojo.codehaus.org/gwt-maven-plugin/user-guide/using-different-gwt-sdk-version.html That being said: when using Maven, you shouldn't use gwt-servlet-deps but instead reference org.json:json and javax.validation:validation-api requestfactory-server can be used instead of gwt-servlet if you only use RequestFactory on the server-side (no GWT-RPC, no SafeHtml, no RegExp, etc.); requestfactory-client is to be used for Java clients (such as Android), not the case here.
