Re: how to close request input stream
I tried a file upload field up to 100MB I tried textfield/textareas up to 600kb ( i must use a slow connection ) it looks like the complete request is send? dont know if tomcat or apache receives those bytes - or in other words - my program leaves its service method... to Tim Funk: What status can I set and respond with my previous form? I guess I've tried that but also I see incoming bytes in my network interface...

Re: how to close request input stream
Hello,
Thanks for your help.
I've tried it but the response (Internal Server Error) is displayed after
the whole file is send...
trying to flush doesn't help either:
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
response.flushBuffer();
response.getWriter().close();
Greetings and Thanks
Peter

Try this and see what happens:
protected void doPost(HttpServletRequest req, HttpServletResponse resp) {
if(req.getContentLength()TOO_MUCH)
resp.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
...
}
I am unsure of how much date is read before the servlet is called. (Which
is probably the crux of the problem)

Is there really no answer? How to cancel a large upload request with a servlet?
Hello, I've written a file upload where the user get's informed of the currently transferred bytes (asynchron with meta refresh)... on this info page the user can press cancel - an async request is send to the server to another thread of course. this thread informs the uploading thread that it could cancel the job - but after leaving my methods someone still reads the whole request. who can it be? tomcat, apache - dont know --- PLEASE HELP It seems that the whole request is still processed. closing the inputstream does not help...

upload and renameto apache-tomcat problem
Hello Tomcat-Community,
I try to figure out a strange but reproduceable error:
Using Apache and Tomcat under windows and maybe linux.
After uploading a file to a temporary dir and renaming (moving) it
to a apache accessible folder i have strange problems...
If i upload a image with the attached servlet and after it accessing the
image with apache i must wait some seconds to get a succesful renameTo. the
problem is that if i don't create the temporary image file with java the
renameTo always succeeds. but the servlet should
have file upload behaviour...
maybe its the FileServletWrapper but uploading multiple times without
accessing the image with apache there is no problem!
ps. The FileServletWrapper is only available as class code...
Any Suggestions?
Thanks
Peter

wanted: pure fast apache servlet enginge without jsp etc. + ASCII/ISO Enc. Prob.
Is there a way to configure tomcat 4.1.24 or is there a better alternative... Also required: -low memory usage -Not much overhead -just simple and pure Also I have a file.encoding problem with tomcat 4.1.24 (Encoding should be ISO8859-1 but defaults to ASCII) Is there a switch in the tomcat configs or elsewhere?

I tried this setup a couple days ago (on Redhat 8.0) and it worked fine, but I am using the mod_jk.so connector. I have not tried the JNI approach. I did notice my applications ran much slower than under the Sun 1.4.1 (both _01 and _02 versions) so I went back to the Sun jdk (despite reports of StringBuffer related memory leaks). I am now on the Apache 2.0.45 and it is working fine. Compiled jni*.so and maybe its the problem because the ././classic/jvm*.so is used? I thought jdk1.4 stops supporting classic jvm...
