We have a Java servlet that sends HTML code to a browser.
The environment is:
Linux RedHat V6.2
JRE V1.2.2/1.3.0 for Linux from Sun
JSDK V2.1 (using servletRunner to run servlet)
Internet Explorer V5.0/5.5
Netscape Navigator V4.5/4.73
Here is the code that sends HTML to the browser (the response object is an
HttpServletResponse):
response.setContentType("text/html");
response.setContentLength(outputStringBuffer.length());
PrintWriter output = response.getWriter();
output.print(outputStringBuffer.toString());
output.flush();
Thread.sleep(5000);
output.close();
Pages sent by this code fail to be displayed under the following
browser-related conditions:
1) IE V5.0/5.5
First time a page is sent to IE, it displays OK.
Second time a page is sent, IE correctly displays the page after the
flush(),
and continues to display it during the 5 second pause. But when the close()
occurs, IE immediately displays its standard "The page cannot be displayed"
error page.
If we wait about 2 minutes before trying to send again, IE displays the page
OK. But if we send again before 2 minutes is up, IE immediately fails to
display the page.
We've seen this IE behaviour when running the servlet under JRE V1.2.2 and
V1.3.0 on a Linux system, but when the servlet runs under JRE V1.2.1 on NT
or
Solaris, IE has no problems.
2) Netscape V4.5
Displays a page OK as long as the pause occurs before the close(). If the
pause is removed entirely, Netscape V4.5 fails to display the page.
3) Netscape V4.73
Always displays a page OK, without or without the pause.
The above occurs for pause values from 2 to 5 seconds.
The same problem occurs when we run the code but not perform the explicit
close().
Has anyone else seen this or similar behaviour?
Thanks,
Kieran Jones
