Struts2整合JasperReport输出HTML显示图片问题

我用的是struts2.0.11，iReport3.6.7
struts2整合JasperReport参考：http://www.blogjava.net/sterning/archive/2008/01/02/172317.html

按照一下方法解决我没有成功：（在浏览器上显示有很多红色XX）

1.web.xml配置
   <servlet> 
        <servlet-name>JasperReportImageServlet</servlet-name> 
        <servlet-class> 
            net.sf.jasperreports.j2ee.servlets.ImageServlet  
        </servlet-class> 
    </servlet>  
    <servlet-mapping> 
        <servlet-name>JasperReportImageServlet</servlet-name> 
        <url-pattern>/image</url-pattern> 
    </servlet-mapping>
2.配置成struts.action.extends=action
3.在WebRoot建立一个images文件夹，放入px文件
若要显示自己在报表中定义的图片，再加上红色部分
<action name="HTMLReport"  class="reportAction">
<result type="jasper">
<param name="location">/jasper/report.jasper</param>
<param name="format">HTML</param>
<param name="reportParameters">map</param>
<param name="dataSource">funList</param>
<param name="imageServletUrl"><![CDATA[/image?image=]]></param>
</result>
</action>

用重写JasperReportsResult.java中的doExcute（）方法
@SuppressWarnings({ "unchecked", "deprecation" })
protected void doExecute(String finalLocation, ActionInvocation invocation) throws Exception {
        if (this.format == null) {
            this.format = FORMAT_PDF;
        }

        if (dataSource == null) {
            String message = "No dataSource specified...";
            LOG.error(message);
            throw new RuntimeException(message);
        }

        if (LOG.isDebugEnabled()) {
            LOG.debug("Creating JasperReport for dataSource = " + dataSource + ", format = " + this.format);
        }

        HttpServletRequest request = (HttpServletRequest) invocation.getInvocationContext().get(ServletActionContext.HTTP_REQUEST);
        HttpServletResponse response = (HttpServletResponse) invocation.getInvocationContext().get(ServletActionContext.HTTP_RESPONSE);

        //construct the data source for the report
        ValueStack stack = invocation.getStack();
        ValueStackDataSource stackDataSource = new ValueStackDataSource(stack, dataSource);

        format = conditionalParse(format, invocation);
        dataSource = conditionalParse(dataSource, invocation);

        if (contentDisposition != null) {
            contentDisposition = conditionalParse(contentDisposition, invocation);
        }

        if (documentName != null) {
            documentName = conditionalParse(documentName, invocation);
        }

        // (Map) ActionContext.getContext().getSession().get("IMAGES_MAP");
        if (!TextUtils.stringSet(format)) {
            format = FORMAT_PDF;
        }

        if (!"contype".equals(request.getHeader("User-Agent"))) {
            // Determine the directory that the report file is in and set the reportDirectory parameter
            // For WW 2.1.7:
            //  ServletContext servletContext = ((ServletConfig) invocation.getInvocationContext().get(ServletActionContext.SERVLET_CONFIG)).getServletContext();
            ServletContext servletContext = (ServletContext) invocation.getInvocationContext().get(ServletActionContext.SERVLET_CONTEXT);
            String systemId = servletContext.getRealPath(finalLocation);
            Map parameters = new ValueStackShadowMap(stack);
            File directory = new File(systemId.substring(0, systemId.lastIndexOf(File.separator)));
            parameters.put("reportDirectory", directory);
            parameters.put(JRParameter.REPORT_LOCALE, invocation.getInvocationContext().getLocale());

            byte[] output;
            JasperPrint jasperPrint;

            // Fill the report and produce a print object
            try {
                JasperReport jasperReport = (JasperReport) JRLoader.loadObject(systemId);

                jasperPrint =
                        JasperFillManager.fillReport(jasperReport,
                                parameters,
                                stackDataSource);
            } catch (JRException e) {
                LOG.error("Error building report for uri " + systemId, e);
                throw new ServletException(e.getMessage(), e);
            }

            // Export the print object to the desired output format
            try {
                if (contentDisposition != null || documentName != null) {
                    final StringBuffer tmp = new StringBuffer();
                    tmp.append((contentDisposition == null) ? "inline" : contentDisposition);

                    if (documentName != null) {
                        tmp.append("; filename=");
                        tmp.append(documentName);
                        tmp.append(".");
                        tmp.append(format.toLowerCase());
                    }

                    response.setHeader("Content-disposition", tmp.toString());
                }

                if (format.equals(FORMAT_PDF)) {
                    response.setContentType("application/pdf");

                    // response.setHeader("Content-disposition", "inline; filename=report.pdf");
                    output = JasperExportManager.exportReportToPdf(jasperPrint);
                } else {
                    JRExporter exporter;

                    if (format.equals(FORMAT_CSV)) {
                        response.setContentType("text/plain");
                        exporter = new JRCsvExporter();
                    } else if (format.equals(FORMAT_HTML)) {
                        response.setContentType("text/html");

                        // IMAGES_MAPS seems to be only supported as "backward compatible" from JasperReports 1.1.0

                        Map imagesMap = new HashMap();

                        request.getSession(true).setAttribute("IMAGES_MAP", imagesMap);
                        exporter = new JRHtmlExporter();
                        exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap);
                        exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, request.getContextPath() + imageServletUrl);
                      //<--begin added by twolf, 20101229
                        exporter.setParameter(JRHtmlExporterParameter.IMAGES_DIR_NAME, request.getRealPath(File.separator) + imageServletUrl);
                        exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR, Boolean.TRUE);
                        //end added by twolf -->
                        // Needed to support chart images:
                        exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
                        request.getSession().setAttribute("net.sf.jasperreports.j2ee.jasper_print", jasperPrint);

                    } else if (format.equals(FORMAT_XLS)) {
                        response.setContentType("application/vnd.ms-excel");
                        exporter = new JRXlsExporter();
                    } else if (format.equals(FORMAT_XML)) {
                        response.setContentType("text/xml");
                        exporter = new JRXmlExporter();
                    } else if (format.equals(FORMAT_RTF)) {
                        response.setContentType("application/rtf");
                        exporter = new JRRtfExporter();
                    } else {
                        throw new ServletException("Unknown report format: " + format);
                    }

                    output = exportReportToBytes(jasperPrint, exporter);
                }
            } catch (JRException e) {
                String message = "Error producing " + format + " report for uri " + systemId;
                LOG.error(message, e);
                throw new ServletException(e.getMessage(), e);
            }

            response.setContentLength(output.length);

            ServletOutputStream ouputStream;

            try {
                ouputStream = response.getOutputStream();
                ouputStream.write(output);
                ouputStream.flush();
                ouputStream.close();
            } catch (IOException e) {
                LOG.error("Error writing report output", e);
                throw new ServletException(e.getMessage(), e);
            }
        } else {
            // Code to handle "contype" request from IE
            try {
                ServletOutputStream outputStream;
                response.setContentType("application/pdf");
                response.setContentLength(0);
                outputStream = response.getOutputStream();
                outputStream.close();
            } catch (IOException e) {
                LOG.error("Error writing report output", e);
                throw new ServletException(e.getMessage(), e);
            }
        }
    }
然后struts.xml添加上
<result-types>
<result-type name="jasper" class="com.wj.common.util.JasperReportsResult" default="false"/>
</result-types>
XX图标就可以消失了。
