Status: Verified
FACT(s) (Environment):
Progress 9.1x
SYMPTOM(s):
Tomcat 3.3
WebClient application / 4GL Application using the AppServer Internet Adapter encounters error at the end of each request to the AppServer server.
Connection failure for host <host_name> port <port> transport <transport_name>. (9407)
Does not want to use the mod_jk plugin with AJP12.
CAUSE:
A problem has been encountered when you integrate Tomcat 3.3 using the mod_jk plug-in with the Apache Web server. Tomcat 3.3 introduces the new mod_jk plug-in, which is a replacement to the older mod_jserv. It provides two possible protocols: Ajp12 and Ajp13, the default being Ajp13.
The problem does not happen when using the Ajp12 protocol, nor with the mod_jserv interface.
You can define the protocol in the mod_jk.conf file for each instance of an application (/examples, /admin, /aia).
FIX:
Switch to the mod_jserv plug-in.
