Web Services Tools (2/15/02)

• Late breaking News from John King, regarding GLUE (http://www.themindelectric.com/).  The GLUE product is free for most non-enterprise (e.g., non-J2EE, etc.) usage, even commercially, so the Groups can definitely download and use it free of charge (if they can get it loaded on whatever machine they are using).  John believes it will be very handy for any Group actually building a Web Service and should speed their progress along (It will avoid getting bogged down in the SOAP and XML parsing implementation details).
