    IMPORTANT TROUBLESHOOTING QUESTION:

    Does the application appear / function correctly when you use the Pocket IE on your device?

    • If NO, then this is not a Wavelink related issue.
      WIB is built on top of Pocket IE. If it doesn't work in Pocket IE, then it will not work in Wavelink Industrial Browser (WIB). The next step should be to work together with your application / server development team to discover why Pocket IE is having issues. Once those issues are resolved, then the issues will likely be resolved within WIB.

    • If YES, then keep reading (specifically check out the WEB Engine Type section)



    Problem/Issue:

    • Pocket Internet Explorer (Pocket IE) works correctly, but the same page appears incorrectly when using Wavelink Industrial Browser (WIB)
    • Wavelink Industrial Browser (WIB) doesn't look and/or work the same as connecting to the host using Pocket Internet Explorer
    • WIB receives a javascript error when connecting to the Emulation session
    • My web page appears incorrect / wrong when using WIB
    • Visual / viewing issues / problems with SAP ITS Mobile application
    • WIB consumes memory continuously with WEB Engine Type set to Enhanced (default)

     

    Resolution:

    • WEB Alternate Browser Support (Windows Mobile Devices Only)
    • WEB Engine Type
    • WEB User Agent

     

    WEB Alternate Browser

    • If it is a device running Windows Mobile, then set WEB Alternate Browser Support to 'Enabled'
      • This setting will attempt to use an alternate browser engine, if one is available on the device.  Currently, only Windows Mobile 6.x devices may have this support, where the build-in Internet Explorer may use a different browser engine than Wavelink uses.

    WEB Engine Type

      • The "Enhanced" engine is required to support several features.  These include:
        • Host Profile proxy settings (Internet Explorer values are used)
        • Host Profile Access List
        • Disable compression
        • Disable cookies
        • Local error messages
        • HTTP version (Internet Explorer values are used)
        • User Agent  (Internet Explorer values are used)
        • Inserting text into the web page
      • However, in some situations, the enhanced engine may cause web pages to load slowly or incorrectly.  If you are having difficulties accessing a web site, selecting the "Standard" engine type may help.
        NOTE: If your Website or Web Application works correctly in Pocket IE, but does not work in default Wavelink Industrial Browser (WIB) then you should definitely try switching the WEB Engine Type to Standard

    WEB User Agent

      • This setting allows you to specify the "User-Agent" value that is included with the HTTP header information sent by the device.  This value is used by the Web Server to determine what type of browser is being run by the device.  Changing this option allows the Web Server to uniquely identify devices running Wavelink WEB emulation.
      • If no value is specified, the User Agent value will be the value that Internet Explorer or Pocket Internet Explorer would use on that device.  The typical default values are listed below.
        • Pocket PC 2003 and Windows Mobile 5:
          •     Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; PPC; 240x320)
        • Windows CE .NET:
          •     Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)


      • WEB_UserAgent.PNG
        • For CE Devices, try using the following:
          • Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)

          • Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; PPC; 240x320)
        • Other WEB User Agents that have fixed issues:
          • Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB7.5; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; BRI/1; MS-RTC EA 2; MALC)
