SmartUpload下载成功但tomcat报错
<%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=UTF-8" import="com.jspsmart.upload.*"%><% // 新建一个SmartUpload对象 SmartUpload su = new SmartUpload(); // 初始化 su.initialize(pageContext); // 设定contentDisposition为null以禁止浏览器自动打开文件， //保证点击链接后是下载文件。若不设定，则下载的文件扩展名为 //doc时，浏览器将自动用word打开它。扩展名为pdf时， //浏览器将用acrobat打开。 su.setContentDisposition(null); // 下载文件 su.downloadFile("/document/"+(String)request.getAttribute("fileName")); out.clear();out=pageContext.pushBody();%>这是我用的下载jsp，用的是SmartUpload这个包做下载，有一个情况会出现这个问题就是在点击下载时（如果装有迅雷或其它下载工具会自动启用）如果关闭下载工具想用浏览器下载就会报如下的错误，现在求一个解决方案，有什么好的下载方式可以避免这个问题的发生。[ERROR]http-8081-10-org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/].[action]-Servlet.service() for servlet action threw exceptionjava.io.IOException at org.apache.coyote.http11.InternalAprOutputBuffer.flushBuffer(InternalAprOutputBuffer.java:696) at org.apache.coyote.http11.InternalAprOutputBuffer$SocketOutputBuffer.doWrite(InternalAprOutputBuffer.java:726) at org.apache.coyote.http11.filters.IdentityOutputFilter.doWrite(IdentityOutputFilter.java:118) at org.apache.coyote.http11.InternalAprOutputBuffer.doWrite(InternalAprOutputBuffer.java:532) at org.apache.coyote.Response.doWrite(Response.java:560) at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:353) at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:352) at org.apache.catalina.connector.OutputBuffer.writeBytes(OutputBuffer.java:381) at org.apache.catalina.connector.OutputBuffer.write(OutputBuffer.java:370) at org.apache.catalina.connector.CoyoteOutputStream.write(CoyoteOutputStream.java:89) [color=#FF6600]at com.jspsmart.upload.SmartUpload.downloadFile(SmartUpload.java:579) at com.jspsmart.upload.SmartUpload.downloadFile(SmartUpload.java:508) at com.jspsmart.upload.SmartUpload.downloadFile(SmartUpload.java:476)[/color] at org.apache.jsp.webs.report.load_jsp._jspService(load_jsp.java:67) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:377) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:646) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:436) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:374) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:302) at org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:1063) at org.apache.struts.action.RequestProcessor.processForwardConfig(RequestProcessor.java:386) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:229) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.jccw.filter.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java:25) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.valves.CometConnectionManagerValve.invoke(CometConnectionManagerValve.java:248) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:861) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:579) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1584) at java.lang.Thread.run(Thread.java:595)
