There is no result type defined for type 'dynamic-jasper' mapped with name 'success'

问题

I am trying to use DynamicJasper 5.0.0 with Struts 2.3.4. I am using following code to show data in PDF format

In action class

try {
    FastReportBuilder drb = new FastReportBuilder();
    DynamicReport dr = drb.addColumn("Size", "size", String.class.getName(), 30).setTitle("Size List Report").setSubtitle("This report was generateed at" + new Date()).setUseFullPageWidth(true) //make colums to fill the page width
            .setPrintBackgroundOnOddRows(true).build();

    JRDataSource ds = new JRBeanCollectionDataSource(getSizeList());
    JasperPrint jp = DynamicJasperHelper.generateJasperPrint(dr, new ClassicLayoutManager(), ds);
    JasperViewer.viewReport(jp);    //finally display the report report   [/CODE]  
} catch (Exception e) {
    System.out.println("Exception");
}
return SUCCESS;

struts.xml

<package name="expotpkg" extends="struts-default, json-default,jasperreports-default"> 
   <result-types>
        <result-type name="dynamic-jasper" class="ar.com.fdvs.dj.webwork.DJResult"/>
    </result-types>

<action name="DownloadSizePdf" class="iland.work.SizesAction" method="fetchDJ">
            <result name="success" type="dynamic-jasper">
                <param name="dynamicReport">dr</param>
                <param name="dataSource">sizeList</param>
                <param name="documentName">Dynamic Report generated with struts 2</param>
                <param name="parameters">params</param>
                <param name="format">PDF</param>
                <param name="layoutManager">classic</param>
            </result>
        </action>
   </package>

While running this I am getting following error

There is no result type defined for type 'dynamic-jasper' mapped with name 'success'.  Did you mean 'dynamicJasper'? - result - file:/E:/Project/cxn/cnx/build/web/WEB-INF/classes/struts.xml:571:58

I have included following jar files

Add this configuration to your package

<result-types>
    <result-type name="dynamicJasper" class="ar.com.fdvs.dj.webwork.DJResult"/>
</result-types>

<action name="DownloadSizePdf" class="iland.work.SizesAction" method="fetchDJ">
    <result name="success" type="dynamicJasper">
        <param name="dynamicReport">dr</param>
        <param name="dataSource">sizeList</param>
        <param name="documentName">Dynamic Report generated with struts 2</param>
        <param name="parameters">params</param>
        <param name="format">PDF</param>
        <param name="layoutManager">classic</param>
    </result>
</action>

The ActionSupport class is under the package name com.opensymphony.xwork2. The error is occurred from the configuration of the plugin you use with Struts2 which is incompatible to the version of Struts you use.
