Zero sized reply - fail to connect servlet
12/21/09 3:55 AM

We use the module servletexec 5.0

ServletExec is used to host and execute servlets of a BMC Remedy application.

We always experiencing fail to connect the BMC Remedy application, when the servlectexec show "zero size reply" on IE.

Everytime restarting the ServletExec engine or the web server to resume.

Has anyone idea of the reason why this kind of error is happening?

When this happens:

1. what is being used as the client?
I understand you are using IE, but I'm asking if the client might be javascript or a java applet that is running inside the IE.

2. What do you see in ServletExec.log when this problem occurs?

3. What do you see in your IIS Access log for the request that returns "zero size reply" as the response?

4. What's the exact version of SE?
5.0?
5.0.0.13?

5. Which version of Windows?

6. Which configuration of SE?
SE ISAPI?
SE AS?

1. Using javascript

2. From the servlet.log, nothing can see, as the log only show "disposing calling..." before problem occur

3. Also nothing can see

4. using 5.0 only
5. not using windows, using linux base

6. the configuration using SE AS

I have no clue to troubleshoot, please help!!

servlet.log is rarely of any use at all.
I was asking you to look in ServletExec.log, ServletExec.log.1, ServletExec.log.2, etc...
for clues.

If you see clues, tell me what they are.
If you don't see clues then I recommend that you apply the latest available SE 5 hotfix (both the native and the JAR components):

http://www.newatlanta.com/c/support/servletexec/self_help/faq/detail?faqId=195

For Apache on Linux/Unix you will need to follow the steps given at the bottom of the ReleaseNotes.txt file to compile the adapter.

Then use SE FAQ #94
http://www.newatlanta.com/c/support/servletexec/self_help/faq/detail?faqId=94

to confirm that you are now running with the updated version.

Then see if the problem still occurs in the same way (no new clues).
If it still occurs in the same way, without any new clues that help to solve it then I recommend you look harder at the webserver's access log (right after the problem occurs) to see what was being requested at the time the problem occurred.

You may also want to consider turning on some debugging within ServletExec. This may be done right on the SE Admin UI under Advanced - debug.
I recommend turning on the "Request" and the "AS" levels of debugging. Ideally you'd turn this on, make the problem occur, and then turn it off right away. Then go look in ServletExec.log for clues about the problem request(s).

When this problem occurs, are you able to use a new browser instance to request something simple such as /servlet/TestServlet ?

Also, you should consider asking BMC/Remedy (the makers of the web application you are running inside SE) if they know of this issue and it's solution... or if they know of ways to troubleshoot it. It may be possible to "turn on" some level of debugging within the BMC/Remedy application that could help to solve this.

I hope something I've suggested helps you.

Sincerely,

Matt
