Dear all,
I would much appreciate it if you could tell me what is going wrong for
me, or at least give me help as to how I may find out more information.
I have an application with a file upload. When I deploy it in Tomcat 6,
I get this exception:
org.apache.commons.fileupload.FileUploadException: Processing of
multipart/form-
data request failed. Connection reset
at
org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadB
ase.java:384)
at
org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(
ServletFileUpload.java:116)
at
ac.otago.flags.server.FileUploadServlet.doPost(FileUploadServlet.java
:*68*)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:710)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
at
org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Appl
icationFilterChain.java:290)
at
org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationF
ilterChain.java:206)
at
org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperV
alve.java:233)
at
org.apache.catalina.core.StandardContextValve.invoke(StandardContextV
alve.java:175)
etc.
My code looks like this:
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
try {
ServletRequestContext ctx = new ServletRequestContext(request);
if (ServletFileUpload.isMultipartContent(ctx) == false) {
sendResponse(response, new FormResponse(
HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
"The servlet can only handle multipart requests."
+ " This is probably a software bug."));
return;
}
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(
new DiskFileItemFactory());
// Parse the request
*List<FileItem> items =
upload.parseRequest(request); // this is the offending line 68*
Iterator<FileItem> i = items.iterator();
HashMap<String, String> params = new HashMap<String, String>();
HashMap<String, File> files = new HashMap<String, File>();
int count = 0;
It may not be relevant, but I have developed the application with GWT
(Google Web Tools). This comes with a hosted mode (which also uses
Tomcat) and that works fine. When I deploy to Tomcat outside of GWT, I
get this exception. I have checked all my jar files, and I believe they
are the same in both environments. I use commons-fileupload-1.1.1 and
commons-io-1.3.2
Many thanks for your help.
Michel
