[Jwap-info] URL Redirection Header Problems

[Domingo M. <dom...@zw...>]

Hi everybody,

I have been testing the jWAP package and it has worked
very well. However, today I found a problem and it seems to me that it is
related with the management of URL redirections (different to a WAP Gatew=
ay
redirection) because there is no method to set a "setFollowRedirects(true=
)".

As a concrete example consider the following URL:

http://wap.tmovil.cl

Using jWAP I receive the following exceptions after been connected to the=
=20
gateway:
****************************************************
Connecting to WAP-Gateway
connected to WAP gateway
GET http://wap.tmovil.cl
java.lang.ArrayIndexOutOfBoundsException: 1
        at net.sourceforge.jwap.wsp.WSPDecoder.getUint8(Unknown Source)
        at=20

rce)
        at net.sourceforge.jwap.wsp.pdu.CWSPPDU.getContentType(Unknown So=
urce)

        at net.sourceforge.jwap.wtp.CWTPInitiator.process(Unknown Source)

Looking for an answer I used the Jakarta HttpClient GetMethod to
get that URL. The results are the following:

****************************************************
Host: wap.tmovil.cl
User-Agent: Jakarta Commons-HttpClient/2.0final

*** Answer Headers ***
Status: HTTP/1.1 302 Found

Content-Length: 0

As you can see the Content-Lenght is 0 and the Status is 302. In this cas=
e
there is no information to get and, obviously, to decode because we have =
a
redirection. The new URL can be found in the header Location as=20
http://wap.tmovil.cl/tmc/portal/index.php

When I use this URL with jWAP everything works without problems:

****************************************************
Connecting to WAP-Gateway

GET http://wap.tmovil.cl/tmc/portal/index.php
jWAP:   decodeContentType: parameter decoding not yet supported

I am going to check the code to find a way to handle it. Even though CWSP=
Reply
have defined the 302 code, I am not pretty sure that CWSPSession is handl=
ing=20
this case (in STATE_RESUMING there is a check for if (pdu2.getStatus() =3D=
=3D=20
CWSPReply._200_OK_Success) but all the other cases implies s_disconnect()=
).

I appreciate any suggestions.
