Question

Configuring the IIS 6 to Tomcat redirector

Asked by: Thread7

I am having all sorts of trouble getting the IIS to Tomcat redirector to work.  Tomcat itself works fine.  Ie. this URL:
http://localhost:8080/examples/servlets/servlet/HelloWorldExample

But when I do this, I just get a blank screen.  
http://localhost/examples/servlets/servlet/HelloWorldExample

In fact, as soon as I go into IIS and do this:
1. Right click on my web site and choose properties.
2. Click ISAPI Filters tab.
3. Add a new filter: C:\Tomcat\ISAPI\isapi_redirect.dll
4. Hit Ok, and then restart Tomcat and World Web Service.
After that, ALL pages on my site pull up blank pages.  It is like the ISAPI redirector intercepts all traffic and tries to send it to Tomcat.  However, Tomcat through IIS doesn't seem to be working anyways.  So I think I have two problems.
1. All traffic to IIS gets sent on to Tomcat, instead of just specific directories.
2. Tomcat through IIS just pulls up blank pages (nothing in view source at all).

Something in my properties files maybe?  I'll post them below:

########isapi_redirect.properties file
extension_uri=/jakarta/isapi_redirect.dll
log_file=C:\Tomcat\logs\isapi_redirect.log
log_level=debug
worker_file=C:\Tomcat\conf\workers.properties
worker_mount_file=C:\Tomcat\conf\uriworkermap.properties 
########## uriworkermap.properties file below
# Default worker to be used through our mappings
/admin/*=wlb
/manager/*=wlb
/examples/*=wlb
/jkmanager=jkstatus 
########## workers.properties file below
# This file provides minimal jk configuration properties needed to connect to Tomcat.
#
# The workers that jk should create and work with
#
worker.list=wlb,jkstatus
#
# Defining a worker named ajp13w and of type ajp13
# Note that the name and the type do not have to match.
#
worker.ajp13w.type=ajp13
worker.ajp13w.host=localhost
worker.ajp13w.port=8009
#
# Defining a load balancer
# 
worker.wlb.type=lb
worker.wlb.balance_workers=ajp13w
#
# Define status worker
#
worker.jkstatus.type=status

    Just an update.  I don't think the three properties files posted above matter one bit.  I ran process monitor and checked to see if those properties files ever get accessed.  They do not.  C:\Tomcat\ISAPI\isapi_redirect.dll gets accessed on every http://localhost/pagename.xxx  call from a browser.  But after restarting services, etc.  Nothing I do makes those properties files get accessed.  
    In fact, I went into the "Computer Management" / "Web Service Extensions", and changed the "Tomcat ISAPI" extension from "Allow" to "Prohibited".  Nothing changed.  All my page calls are still blank.  If I delete the Tomcat ISAPI extension that I created in IIS, and restart the World Wide Web service.  Then I at least get my non-Tomcat pages to work.  Ie. http://localhost/frontpage.html
    But C:\Tomcat\ISAPI\isapi_redirect.dll is gettig accessed on every call from a browser.  Even with "Prohibit" set up in "Web Service Extensions".  
    One more thing.  I an using Win 2003 64-bit.  All the java, tomcat, and isapi dlls I installed are 32-bit.  Right now, I am leaning towards thinking that this is not a problem.  After all, tomcat on port 8080 works fine.
    Any ideas?

    This is an excellent walk-through of how to configure IIS and Tomcat:
    http://it.megocollector.com/?p=224

    I don't think you've done several of the steps, although I can't be sure.  If you truly have only done what you documented, then you're missing some configuration.

    It would probably help you to look at the Tomcat doc for the IIS connector as well:
    http://tomcat.apache.org/connectors-doc-archive/jk2/jk/iishowto.html

    but I would start with the first link.

    I figured it out.  It was actually the 64-bit / 32-bit thing.
    I had to run this at a command prompt to enable IIS to use 32-bit ISAPI dll's.

    cscript %SystemDrive%\inetpub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1
