Hi, I placed the the exact same Chart.java from http://wiki.apache.org/tapestry/Tapestry5HowToCreateGenericGraphComponent under the package 'com.mycompany.myproject.webapp.components'. My tapestry version is 5.1.0.5. And I use jfreechart 1.0.12.
here is my \src\main\webapp\reports\LineChartPage.tml; <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";> <body> <h1>Line Chart</h1> <t:chart width="200" height="150" chart="lineChart"/> </body> </html> And below is the LineChartPage.java under package com.mycompany.myproject.webapp.pages.reports; public class LineChartPage { public JFreeChart getLineChart() { XYSeries series = new XYSeries("Average Size"); series.add(20.0, 10.0); series.add(40.0, 20.0); series.add(70.0, 50.0); XYDataset xyDataset = new XYSeriesCollection(series); final JFreeChart chart = ChartFactory.createXYLineChart ("Sample XY Chart", // Title "Height", // X-Axis label "Weight", // Y-Axis label xyDataset, // Dataset PlotOrientation.HORIZONTAL, true, // Show legend true, // Tooltips true // Urls ); return chart; } } Everything seems to be right but I get the exception; 20:39:44,240 ERROR [RequestExceptionHandler] Processing of request failed with uncaught exception: Sanity check - neither a stream response nor a redirect response was generated for this action request. java.lang.IllegalStateException: Sanity check - neither a stream response nor a redirect response was generated for this action request. at org.apache.tapestry5.internal.services.ImmediateActionRenderResponseFilter.handle(ImmediateActionRenderResponseFilter.java:63) at $ComponentEventRequestHandler_12a675b8084.handle($ComponentEventRequestHandler_12a675b8084.java) at org.apache.tapestry5.internal.services.AjaxFilter.handle(AjaxFilter.java:42) at $ComponentEventRequestHandler_12a675b8084.handle($ComponentEventRequestHandler_12a675b8084.java) at org.apache.tapestry5.upload.internal.services.UploadExceptionFilter.handle(UploadExceptionFilter.java:75) at $ComponentEventRequestHandler_12a675b8084.handle($ComponentEventRequestHandler_12a675b8084.java) at org.apache.tapestry5.services.TapestryModule$36.handle(TapestryModule.java:2164) at $ComponentEventRequestHandler_12a675b8084.handle($ComponentEventRequestHandler_12a675b8084.java) at $ComponentEventRequestHandler_12a675b7fca.handle($ComponentEventRequestHandler_12a675b7fca.java) at org.apache.tapestry5.internal.services.ComponentRequestHandlerTerminator.handleComponentEvent(ComponentRequestHandlerTerminator.java:43) -----Original Message----- From: Chuck Kring [mailto:cjkr...@pacbell.net] Sent: Tuesday, August 10, 2010 8:28 PM To: users@tapestry.apache.org Subject: Re: Stream redirection problem when using JFreeChart with Tapestry Hi. I use JfreeChart extensively with T 5.0.1.5 and I'm very happy with it. Most likely your exception is caused by a bug in your .tml or the underlying class. If you could reduce the template and the class to the minimum size that still shows the bug and post both to a follow up email, somebody on the list will probably be able to help you.
