Hi,
I am using struts framework, I do have a module export to excel, where in some big Mb's of data can be exported to excel by a client. As part o the implementation I have an action which calls a DAO object. This DAO object dumbs the whole data to excel File. The action picks up this file and writes the whole thing to the ServletOutputStream. In the logs I am finding a Response Already commited exception
" [6/22/06 6:24:09:830 EDT] 110d2e6a WebGroup E SRVE0026E: [Servlet Error]-[Cannot forward. Response already committed. (Servlet 2.3, SRV 8.4)]: javax.servlet.ServletException: Cannot forward. Response already committed. (Servlet 2.3, SRV 8.4)
I fear this is causing memory leaks and eating up the whole CPU resources on the web-server, which is causing us to restart the JVM frequently.
Can any one help me in fixing this issue.
Thanks and Regards,
Hari
The code which downloads the excel file is :
========================================================
private void downLoadTheExcelFile(String fileName, HttpServletResponse response) throws IOException {
FileInputStream inputStream = new FileInputStream(fileName);
boolean flag = true;
response.setHeader("Content-Disposition", "attachment;filename=ECOMatrix.xls");
response.setContentType("application/vnd.ms-excel");
char c = '\u5000';
ServletOutputStream servletOutputStream = response.getOutputStream();
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(servletOutputStream);
int abyte0 = 0;
while ((abyte0=inputStream.read()) != -1) {
bufferedOutputStream.write(abyte0);
inputStream.close();
bufferedOutputStream.flush();
File file = new File(fileName);
file.delete();
/* /opt/httpd/logs/apps/ecom/ecom-9962/EcoMatrix1141911660345.xls */
