Thanx a lot. After I insert "return null" the exception about > 16:52:20,832 ERROR [UIBean] error when rendering > java.lang.IllegalStateException: getOutputStream() has already been called > > for this response
stopped. But I've still got the problem with IE6 - instead of file name I have the name of my action - as I understand IE6 takes the last part of my url because it looks like filename (dot) extension (FileContent.action?fileId=5067). And it is strange because it happens only when I use https and IE6. When it is http and IE6 it seems to be fine. Could anyone help with this stuff? Thank you very much!

You execute() method should be returning 'null' to tell Struts not to do this. > And the second part of my problem happens only in IE6 - when dialog of > opening/saving file instead of normal file name like myTest.pdf reflect the > action name - something like this: FileContent_action?fileId=5046 (only when > I use https - in http it looks fine - myTest.pdf). The file name to save to is specified by the Content-Disposition header, which you are not setting consistently. Sending a correct header every time should fix this problem.
