数据导入excel中出现的问题。急
2012-7-11 17:16:10 org.apache.catalina.core.ApplicationDispatcher invoke
严重: Servlet.service() for servlet jsp threw exception
java.lang.IllegalStateException: getOutputStream() has already been called for this response
at org.apache.catalina.connector.Response.getWriter(Response.java:610)
at org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:198)
at javax.servlet.ServletResponseWrapper.getWriter(ServletResponseWrapper.java:112)
把数据导入到excel中出现的错误。网上说在页面中加上
out.clear();
out=pageContext.pushBody();
但是我加上之后这个页面中的内容就不显示了。
请问我该怎么处理这个问题
