在我的项目引用库中，我有：hibernate-validator-4.1.0.Final.jar

但是当我运行我的项目时，我得到了

[WARN] Server class 'org.springframework.asm.ClassVisitor' could not be found in the web app, but was found on the system classpath

你看过file:/C:/Applications/eclipse/plugins/com.google.gwt.eclipse.sdkbundle_2.4.0.v201208080121-rel-r42/gwt-2.4.0/doc/helpInfo/webAppClassPath.html吗？

答案就在那里：服务器端 JAR 应该在WEB-INF/lib中。
