Hi Guys, I am working with GWT and everything is working pretty well in Eclipse + Jetty
But I need to migrate this webapp to Tomcat 7. I have been able to deployed the app correctly but when I want to use it I am getting the next Exceptions Nov 4, 2014 4:28:06 PM org.apache.catalina.core.ApplicationContext log *SEVERE: Exception while dispatching incoming RPC call* *com.google.gwt.user.server.rpc.UnexpectedException*: Service method 'public abstract com.client.model.UserInfo com.client.service.users.UsersService.isValidPassword(java.lang.String,java.lang.String)' threw an unexpected exception:* java.lang.UnsupportedClassVersionError: org/apache/commons/dbcp2/BasicDataSource* at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:389) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:579) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:265) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:305) at com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet.doPost(AbstractRemoteServiceServlet.java:62) at javax.servlet.http.HttpServlet.service(Unknown Source) at javax.servlet.http.HttpServlet.service(Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(Unknown Source) at org.apache.catalina.core.StandardContextValve.invoke(Unknown Source) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(Unknown Source) at org.apache.catalina.core.StandardHostValve.invoke(Unknown Source) at org.apache.catalina.valves.ErrorReportValve.invoke(Unknown Source) at org.apache.catalina.valves.AccessLogValve.invoke(Unknown Source) at org.apache.catalina.core.StandardEngineValve.invoke(Unknown Source) at org.apache.catalina.connector.CoyoteAdapter.service(Unknown Source) at org.apache.coyote.http11.AbstractHttp11Processor.process(Unknown Source) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(Unknown Source) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1146) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:679) *Caused by: java.lang.UnsupportedClassVersionError: org/apache/commons/dbcp2/BasicDataSource* I have been researching on internet but I have not found any possible solution Any ideas?
