Greetings, In case this article looks long I have given a brief summary at the end. The lengthy paragraphs that are seen below could not be helped. I am trying to be as brief as possible without cutting the details.
I downloaded the hello.wml file from the wapit.com site which is used as a test file for the fakewap application. I renamed hello.wml to hello.xml and invoked the same via a Ericsson R380 emulator (the IP address of the machine where Kannel is installed was set as the gateway address in the Ericsson emulator) I got Error message "Browser cant read text/html content" Next I copied a wap.xml file which was stored in the $LIBXML_HOME/test folder(I assume this XML file outputs WAP content) to the location where my Apache http server looks for requested files. I tried to invoke wap.xml in the Ericsson emulator, but again the same result- "Browser cant read text/html content" I checked the Kannel logs both times, after a series of Octet strings the ending line was: "Fetched URL/<xml-file-name> (text/html,charset="") Refusing to give up I was bent upon making Kannel extract the WAP content out of any well-formed XML file. So I configured the XML engine Cocoon to process all XML requests sent to Apache. In a sample XML file lying in the Cocoon folder I replaced all HTML tags to WML tags and placed it in the DocumentRoot of Apache. A third invocation of the XML file (.i.e the sample Cocoon XML file outputting WAP content) should have made Kannel recognize the output and succesfully pass it on to Ericsson R380 emulator. BUT again "Browser cant read text/html content" Thoroughly frustrated now I wrote a servlet program which outputs WAP content and invoked the servlet via Kannel, this time I hit the jackpot Ericsson R380 displayed the servlet's output. I called hello.wml (mentioned above) and again Ericsson is displaying the output. All these experiments lead me to believe that whenever Kannel sees a .xml extension in the URL it fetches the output of the XML file and(even if it is proper WAP content) passes this output to the GNOME XML library. This in turn fails the OUTPUT of the XML files I have been trying to invoke. Any diagnostic help- as to why Kannel fails to recognize the content-type of the XML files and labels the content-type as text/html even though these XML files output proper WAP content- would be appreciated. To help the people here I have drawn a small diagram which explains the short setup that I have on my system: ___________ ________________ | ERICSSON| REQUEST FOR WAP CONTENT GENERATING XML FILE | KANNEL | | R380 |_____________________\\__________________________| ____________ | | EMULATOR| // | | BEARERBOX| | |_________| | |__________| | | | | + | | _________ | | | WAPBOX| | | |_______| | |______________| | | R | E | Q \|/U \|/E | S | T | | P | A | S | S __________ | E | APACHE | TO APACHE | D _____\\____| HTTP |________________//_________________| | // | WEB | \\ | | SERVER | XML | |________| OUTPUT | | SENT | | XML BACK /|\ \|/ PROCESSING TO /|\ \|/ REQUEST REDIRECTED APACHE | | TO COCOON | ____|____ | | COCOON| |____//____| XML | \\ | ENGINE| |_______| I am summarizing the actions once more here: 1) RENAMED hello.wml TO hello.xml FILE. BUT text/html 2) COPIED SAMPLE libxml2 (WAP-GENERATING) XML FILE TO APACHE DOCUMENTROOT STILL text/html 3) CONFIGURED XML ENGINE COCOON WITH APACHE. IN SAMPLE COCOON XML FILE REPLACED HTML TAGS WITH WML TAGS. BUT STILL text/html 4) WROTE A SERVLET PROGRAM, SET CONTENT-TYPE AS text/vnd.wap.wml AND HURRAH OUTPUT OF SERVLET SEEN IN ERICSSON R380 5) CONCLUSION: WHENEVER KANNEL SEES .xml EXTENSION, FETCHES OUTPUT AND PASSES IT ON TO libxml2. GNOME XML LIBRARY FAILS TO PROCESS OUTPUT AND LABELS IT AS text/html Thanks in advance. SNODX
