[vtp-dev] VXI* VoiceXML browser, OpenVXML and Tomcat does UTF-8 in URL c

["Rajah Kalipatnapu" <kalipats@xxxxxxxxx>]

I've created an ivr web app using OpenVXML studio. The process is smooth. I  exported it as a webapp and deployed with Tomcat. 

I'm using vxml browsers VoiceGlue (open source) and VXI* VoiceXML demo versions to prototype and evaluate the solution for our application.

The  problem we are facint is observed with both the browsers. 

This is the problem. 

1. When the call started the initial/root vxml is downloaded and parsed fine. 
2. The next URL sent to Tomcat 
3.  Tomcat sends 404/402. 
4. Call drops.

Observations:

1. Actual URL - http://localhost:9090/mediaivrapp/-/next;jsessionid=B75CD6DCECB6A1202F1D29155C23B5F7?cbb0fc79382a4f039e6f8eb5fef8b1cd=success.filled&ANI=781871222&DNIS=617428444

2. URL logged at Tomcat  /mediaivrapp/-/next%3Bjsessionid%3DB75CD6DCECB6A1202F1D29155C23B5F7?cbb0fc79382a4f039e6f8eb5fef8b1cd=success.filled&ANI=781871222&DNIS=617428444

The problem seems to be due to the fact that Tomcat does not support UTF-8 by default.  For example VoiceGlue and i6.net voicexml browsers both sending the URL in the form shown in 2. 

As you see the ";' and "=" characters are converted to UTF-8 Ascii codes by the voice xml browser and this seems to be causing the Tomcat not to map it to the right resource and return 404. 

Where as if I manually treverse through the VXML using IE it works fine and IE sends the URL in ISO-8859-1 format and does not convert them to UTF-8.

This is the peice of information, I found.

"ISO-8859-1 to UTF-8. ISO-8859-1 is the default character encoding for servers and browsers according to the  HTTP specification section 3.4.1."

And it seems Tomcat is also by default using ISO-8859-1.

I've modified Tomcat server.xml to add UTF-8 encoing in the Connector. But still it didn't work. 

This is blocking our validation of OPenVXML and VoiceGlue.  I appreciate and help. 

Thanks in Advance,
