2.No report compiler set for language : null
3.JSP 报错为org.apache.jasper.JasperException: /t3.jsp(4,源码4) Invalid directive 可能是哪方面的原因啊
4.jasperreport applet打印预览在jboss上显示不全(本地用jetty没有问题),可能是什么原因呢?如何解决

Invalid directive
看看有没有类似以下的源码,有的源码话把能去的空格都去掉,将空格去掉!将中间不应该要的源码自动回复网站源码空格都去掉!
<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb" %>
改成<%@page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb"%>
jasperreport applet打印预览在jboss上显示不全(本地用jetty没有问题),可能是什么原因呢?如何解决
产生原因:在生成HTML页面时JRHtmlExporterParameter.IMAGES_URI参数设置不正确,主要是源码的路径问题。由JasperReport生成Html时,源码编程猫可看源码吗那些红叉叉是源码主力拉升行踪指标源码一个名称为px像素的,是源码内置在jasperreports包中的,在IE显示时以的源码形式显示 解决办法:根据JasperReport的源代码显示,我们只需要以下两个步骤就能解决了1、源码在web.xml中添加如下配置: <servlet> <servlet-name>ImageServlet</servlet-name> <servlet-class>net.sf.jasperreports.j2ee.servlets.ImageServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>ImageServlet</servlet-name> <url-pattern>/servlets/image</url-pattern> </servlet-mapping> 2、源码在调用程序中增加如下代码: exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,源码 "../servlets/image?image="); 好了,经过上面两个步骤。源码重启服务,源码通讯协议原理与源码刷新页面立马就正常了 完整代码: /** * 导出html */ private static void exportHtml(JasperPrint jasperPrint,源码String defaultFilename, HttpServletRequest request, HttpServletResponse response) throws IOException, JRException { response.setContentType("text/html;charset=UTF-8"); JRHtmlExporter exporter = new JRHtmlExporter(); PrintWriter out = response.getWriter(); try { request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out); exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, Boolean.FALSE); exporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "UTF-8"); exporter.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,Boolean.FALSE); exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "../servlets/image?image="); exporter.exportReport(); } catch (JRException e) { logger.debug(" 生成html文件失败 .... ...."); } } 上面的代码就能很完美的生成html了,页面没有红叉叉,源码淘宝自动采集软件源码chat图也能正常显示了
