JRun 3.x: How to Read Verbose JRun Connector Logs

The following article explains how to interpret verbose JRun connector logs.

To set your connector log to verbose, set the verbose=true setting in the connector properties. For IIS, add the setting in the jrun.ini file in the scripts folder. For Apache, NES and iPlanet add the setting in the web server configuration file. This will set your connector log to verbose output.

Below, the verbose log is from a Windows NT machine running JRun 3.1 and IIS. In this case, a Microsoft Internet Explorer 5.5 Browser makes a request to http://localhost/demo/ and produces the verbose log below.

Explanation	Log File in Verbose Mode
This indicates the beginning of a connector request.	`20:07:56 jrISAPI[filter] In filter: notification = 0x00004000`
The connector gets the /demo/ mapping from the rules section.	`20:07:56 jrISAPI[filter] JRun Filter got url: '/demo/'`
The connector refreshes the url mappings from the rules section.	`20:07:56 jrISAPI[filter] refreshing mappings for default`
The connector gets the default server mappings.	`20:07:56 jrISAPI[filter] default fetching servlet-mappings`
Mappings received.	`20:07:56 jrISAPI[filter] PROXY_PUT_PROPS <- [1384]`
Listing of all mappings from the rules section of the JRun properties files.	`20:07:56 jrISAPI[filter] /invoice = invoice-app` `20:07:56 jrISAPI[filter] /servlet = default-app` `20:07:56 jrISAPI[filter] /demo = demo-app` `20:07:56 jrISAPI[filter] .shtml = default-app` `20:07:56 jrISAPI[filter] .thtml = default-app` `20:07:56 jrISAPI[filter] .jrun = default-app` `20:07:56 jrISAPI[filter] .jsp = default-app` `20:07:56 jrISAPI[filter] *.cab = default-app`
Returning this thread to the pool.	`20:07:56 jrISAPI[filter] default returned [1384] to pool`
Installing the new url mappings.	`20:07:56 jrISAPI[filter] installing new mappings for default`
Lists the host name (the request was made to localhost here).	`20:07:56 jrISAPI[filter] HTTP_HOST: localhost`
Filters the response by mapping /demo/.	`20:07:56 jrISAPI[filter] filtering /demo/ (/demo/) HOST=localhost`
Matches /demo/ with /demo in the rules section.	`20:07:56 jrISAPI[filter] matched /demo`
Executes the JRun ISAPI filter using the current request url.	`20:07:56 jrISAPI[filter] JRun Filter mapped url to: '/scripts/jrun.dll/demo/'.`
