Subject Problems with MIME-type mappings
Date Wed, 20 Dec 2000 08:40:23 GMT
Hi folks,

I have recently started to use a tomcat-3.2.1 instead of the
old tomcat-3.1 version  and  encountered a strange configuration problem.

Currently I have mapped the old tomcat version 3.1  to the port 8080 and
new one (3.2.1) to  8088. Both use the same  /conf/web.xml file (with no 

[immo@jimbo immo]$ diff jakarta-tomcat/conf/web.xml  
[immo@jimbo immo]$    

which also includes the appropriate  MIME-mapping for wap/wml-MIME type:

I also imagine that both server.xml configuration files are properly 
configured (?), TOMCAT_HOME
is set. etc....         

I have the same  application (or the context) on both versions ,
this is under the 3.2.1.-version:

[immo@jimbo immo]$  ls jakarta-tomcat-3.2.1/webapps/spll/*
classes  lib  web.xml  web.xml~

SPLLregister.wml  start.wml  start.wml~  

and exactly the same structure under tomcat-3.1 folders:

[immo@jimbo immo]$ ls jakarta-tomcat/webapps/spll/*
classes  lib  web.xml  web.xml~

SPLLregister.wml  start.wml  start.wml~   

so basically those are identical.

But now the  problem- when accessing
different tomcat versions the HTTP Content-type
headers differ. Here is what is given form the new version (tomcat-3.2.1)
(accessing the port via telnet for a demonstrating purpose):

[immo@jimbo immo]$ telnet localhost 8088
Connected to
Escape character is '^]'.
GET /spll/wml/start.wml HTTP/1.0

HTTP/1.0 200 OK
Content-Type: text/plain
Content-Length: 1552

1.3.0beta; Linux 2.2.14-5.0 i386; java.ven
dor=Sun Microsystems Inc.)

<?xml version="1.0"?>

and here is from the old version (Tomcat-3.1):

[immo@jimbo immo]$ telnet localhost 8080
Connected to
Escape character is '^]'.
GET /spll/wml/start.wml HTTP/1.0

HTTP/1.0 200 OK
Date: Wed, 20 Dec 2000 08:17:42 GMT

Content-Type: text/vnd.wap.wml
Last-Modified: Sat, 16 Dec 2000 10:44:32 GMT
Content-Length: 1552
Content-Language: en

<?xml version="1.0"?>`

Note the difference : text/plain versus text/vnd.wap.wml !  Now the
question is , what I'm doing wrong or what/how should I configure
Tomcat 3.2.1 that the  /conf/web.xml  - file will also be valid for the 
(so that I will get a text/vnd.wap.wml - header  from.wml files ) ??
Now it doesn't seem to have any effects with Tomcat 3.2.1.

Servlets are working similar way on both configurations, but these static
wml-files are the problem.

Any help is appreciated !
