Hello, we have developed an application using JSP. Our development environment was a NT workstation with PWS on it. Tomcat 3.2.1 provided the JSP support and all was well. Yet, now we are trying to get Tomcat going on a NT Server 4 with IIS4 on it, but somethings wrong. The IIS server responds normally, but when we call on the Tomcat (through the isapi filter) eg http//servername/examples we always get a DR Watson error telling us that there has been an access violation (in inetinfo). Afterwards IIS does not respond at all anymore. When viewing the log I can see that the http-filter spots the existance of a mapping to the ajp worker, but that's where it ends. We us JDK1.3. Since we're operating in a narrow window we have to get Tomcat going very fast or opt for another servlet engine. However, since we have developed using Tomcat, a solution would be greatly appreciated. Thanks in advance, Koen Verhoeven Internet Consultant - Cronos +32 2501 26 53 [EMAIL PROTECTED]
