I am using Tomcat with 64 bit and it runs all the classes fine. I am compiling them to 32 bit on another computer as my dedicated online server is 32 bit and tomcat is connected with apache through mod_jk connector.
This code is working fine on offline computer but when am uploading my class to online dedicated server it prints "Only zip file is accepted".
I checked and printed the file type in 3 different browsers and browser showing correct file type i.e. application/zip
Is there any problem with apache or tomcat or anything else?
Leave that out. f14 is a File object and will never be equal to any String.
That if statement will always be executed. You're saying that if the file type is not application/zip or not application/x-zip-compressed the block should be exected. Since these two Strings are different, the file type will always be different from one of the two; if it's application/zip then it's not application/x-zip-compressed and vice versa. Change the || into &&, and the block will be executed if the file type is neither of the two Strings - exactly what you want.
