Idoox have released the first beta of a SOAP JavaScript client with SOAP 1.1 and WSDL 1.1 support, available for free through their Early Access Program.

Features include:

• Automated JavaScript, HTML and XML/XSL code generation from WSDL.
• Easy customization of generated code through XSL stylesheets.
• Reasonable subset of XML Schema support and Namespaces.
• SOAP message tracking

MSIE 5.x and higher browsers, with MSXML 3.0 installed, are currently supported. Work is in progress to add support for Mozilla and standalone JavaScript engines.
