Web Service - Service Unavailable message

[ChrisClark]

Hi,

I'm having an issue with running a web service where the browser page when I'm trying to test the method (URL: http://localhost/jade/jadehttp.dll?Router) is returning "Service Unavailable" - This Service is currently unavailable at this time.

When trace is turned on - I get the following in the log file:
2010/08/25 22:27:28.859 01474-151c Trace Info - Received request Application=Router

2010/08/25 22:27:28.875 01474-151c Request rejected - service unavailable

Which would possibly suggest the dll version is different from what is expected, though I have copied it from the bin folder the jade system is running from. I have made sure the dll has permissions to run in IIS web extensions so I'm at a bit of a loss as to what is going wrong.

Does anyone have any thoughts on where to look at next?

Thanks.

Hi Chris,

Have you tried restarting the w3 windows service on the IIS server (or restarting the web site), sometimes IIS can keep the dll in memory and not pick up changes.

Alternatively, have you checked that the version of the jadehttp.dll matches the JADE version of the web application that you are connecting to? i.e The version of the JADE web service application listening on DEV port=4010

regards,
Dr Danyo

Thanks for the reply. I've restarted the IIS websites/applications and removed/re-added the dll as a valid web extension but doesn't seem to make any difference.

At the start of the trace file it has "Starting jadehttp.dll Version 6.3.05.002" which matches what is visible in the dll properties window for jadehttp.dll.

I run jverinfo.exe and it provides the following information

Now I assume that when the database server is started (jadrap) that the web service will be running under that version(?). (note I think that the later jade.exe version is due to some hotfixes being applied to the system)

I have also downloaded Jade 6.3.06 and copied the jadehttp.dll from the bin across to the system I am working with (the dll is version 6.3.06.003) and after restarting IIS the new dll is detected (version displayed in the trace file) however the same version check failed error occurs.

Hi Chris,

The original log sample you supplied shows jadehttp.dll is getting a 10054 error when attempting to communicate on port 4010. This is a TCP error raised by the operating system and is summarised as:

10054

WSAECONNRESET -- Connection reset by peer. This occurs when an established connection is shut down for some reason by the remote computer.

Is there a local firewall that's blocking activity on port 4010? Can you use another port, e.g. 6305, is this more successful?

Thank you,

[ChrisClark]

Thanks for your replies. It wasn't a firewall issue in the end - probably just an understanding issue on my part but I had the ConnectionName parameter matching the application name when it needed to be the URL + port of the connection. Once this was updated to be URL + port (localhost:4010) then everything worked beautifully.
