Hello everybody!
I am trying to load file from DB. I use https. In Mozilla I get only one
exception but everything finally works. Here is my code and stack trace:
public String execute() throws Exception {
super.execute();
byte[] file = null;
PolicyFileVO policyFile = polInfoInstance.getPolicyFileById(fileId);
file = policyFile.getFile();
String fileType =
polInfoInstance.getFileTypeById(policyFile.getType())
.getContentType();
if (file != null) {
this.response.setCharacterEncoding("utf-8");
String fileName = policyFile.getFile_name();
if (!fileType.startsWith("image")) {
this.response.addHeader("Content-Disposition",
"attachment; filename=" + fileName);
}
// final ServletContext sc =
ServletActionContext.getServletContext();
this.response.setContentType(fileType);
this.response.setContentLength(file.length);
OutputStream o = null;
try {
o = response.getOutputStream();
o.write(file);
o.flush();
} catch (java.lang.IllegalStateException ex) {
log.error("IllegalStateException in FileContent.execute()
method " + ex);
}catch (java.io.IOException ex) {
log.error("IOException in FileContent.execute() method
" + ex);
}catch (java.lang.Exception ex) {
log.error("Exception in FileContent.execute() method "
+ ex);
}finally{
if (o != null){
response.flushBuffer();
o.close();
}
}
}
There's no return statement in there, which shouldn't even compile...

This suggests Struts is trying to forward to a JSP after your action
completes, which won't work since you've already sent a file back to the
browser. 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.
