Subject Re: jk 1.2.14 connector connection problem
Date Mon, 03 Sep 2007 03:53:07 GMT

Just in case any other poor soul is trying to sort out such an error, thought
I'd post my discovery after 6 hours of hair pulling...!

The documentation I was following to set up the ISAPI redirector stated that
I should create the ISAPI filter on the Web Sites folder in IIS. I did this,
and all was well until I created a second website on my IIS server. I had
the Default Web Site set up already, and decided to create a temporary
'SiteDown' website to serve up an information page while the main site was
down and Tomcat being upgraded.

Once I restarted IIS, it seems that either IIS or the ISAPI filter, I'm not
sure which, decided that incoming requests picked up by the filter should be
forwarded to my SiteDown web site instead of (or possibly as well as) my
Default Web Site. Since I hadn't created the jakarta virtual directory in my
SiteDown website, this didn't work! My solution was to create the filter on
the Default Web Site and remove it from the Web Sites folder.

The key error message in the ISAPI redirect log file that indicates that
this is your problem is:
[/jakarta/isapi_redirect.dll] is not a servlet url.
