Build Identifier: 20100617-1415 I am trying to run a report on the server side of my GWT app when a certain RPC takes place. So the client clicks a button and then on the server side the report is run. I get to the point where I call task.run() and this is when I get the error. I know that the BIRT code is sound because if I separate it and add a main method and run it on its own it runs fine. This error may be related in a way to bug 203703 but that deals with Websphere where I'm just running a GWT webapp. Here is my stack trace: [WARN] Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract java.lang.String com.gwt.ReportGeneration.client.ReportGenerationService.getReport(java.lang.String)' threw an unexpected exception: java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.birt.chart.reportitem.i18n.Messages at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:378) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:581) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:207) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:243) at com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet.doPost(AbstractRemoteServiceServlet.java:62) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:362) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:729) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.handler.RequestLogHandler.handle(RequestLogHandler.java:49) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:324) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:505) at org.mortbay.jetty.HttpConnection$RequestHandler.content(HttpConnection.java:843) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:647) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:211) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488) Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.birt.chart.reportitem.i18n.Messages at org.eclipse.birt.chart.reportitem.ChartReportItemImpl.validate(ChartReportItemImpl.java:776) at org.eclipse.birt.report.model.api.validators.ExtensionValidator.doValidate(ExtensionValidator.java:142) at org.eclipse.birt.report.model.api.validators.ExtensionValidator.validate(ExtensionValidator.java:81) at org.eclipse.birt.report.model.validators.ValidationNode.perform(ValidationNode.java:133) at org.eclipse.birt.report.model.validators.ValidationExecutor.perform(ValidationExecutor.java:79) at org.eclipse.birt.report.model.core.DesignElement.validateWithContents(DesignElement.java:2121) at org.eclipse.birt.report.model.core.DesignElement.validateWithContents(DesignElement.java:2130) at org.eclipse.birt.report.model.core.Module.semanticCheck(Module.java:1168) at org.eclipse.birt.report.model.core.LayoutModuleImpl.semanticCheck(LayoutModuleImpl.java:301) at org.eclipse.birt.report.model.core.LayoutModuleImpl.doClone(LayoutModuleImpl.java:1071) at org.eclipse.birt.report.model.elements.ReportDesignImpl.doClone(ReportDesignImpl.java:309) at org.eclipse.birt.report.model.api.ModuleHandle.copy(ModuleHandle.java:3050) at org.eclipse.birt.report.engine.api.impl.ReportRunnable.cloneRunnable(ReportRunnable.java:132) at org.eclipse.birt.report.engine.api.impl.EngineTask.prepareDesign(EngineTask.java:1743) at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.doRun(RunAndRenderTask.java:99) at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.run(RunAndRenderTask.java:77) at com.gwt.ReportGeneration.server.ExecuteReport.runReport(ExecuteReport.java:165) at com.gwt.ReportGeneration.server.ReportGenerationServiceImpl.getReport(ReportGenerationServiceImpl.java:31) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:562) ... 22 more [ERROR] 500 - POST /com.gwt.ReportGeneration.ReportGeneration/report (127.0.0.1) 57 bytes Request headers Host: 127.0.0.1:8888 User-Agent: Mozilla/5.0 (X11;

Try and programmatically run a report then you will get the error.
