    Browser – opens a Classes Browser on the current component
    Inspector – opens an Inspector on the current component
    Style Editor – opens an editor used to tweak the stylesheet associated with the component
    Source View – show a “pretty-print” of the HTML for the component instead of rendering it

  • As web services continue to evolve, the wrapped document literal style has become extremely popular.
    .Net uses wrapped literal style by default.
    Wrapped Literal
    has the advantage of including the operation name – the name of the input wrapper element must be the same as the operation name.
    allows the use of modularized schemas which are imported in the “Types” section of the Wsdl document, making schema maintenance easier and facilitating reuse of existing schemas.
    The current web services framework does not readily support multiple nested schema imports, although it is possible with customization. It also does not currently support looping schema imports. In Version 8, no customization will be necessary; the default Document Literal processing will handle wsdl and schema files with these characteristics.
    Multiple nested schemas
    Schema A imports schema B which import schemas C and D
    Looping schema imports
    Schema A imports schema B which imports schema C which imports Schema A
    "It is legal to have multiple imports of the same namespace. Even looping references (ord1.xsd imports prod.xsd's namespace, and prod.xsd imports ord1.xsd's namespace) are acceptable, because this just indicates the interdependence of the components."
    From p73 of Definitive XML Schema, Priscilla Walmsley, ISBN 0-13-065567-8
  • VA Smalltalk Web Services documentation lacks a coherent step-by-step description of creating and deploying a web service. The information is there, but it is scattered in different sections of the Web Services Guide and the ReadMes of several releases. With Version 8, we will consolidate the information in one document where it is easily found and referenced.
  • Simplifies porting
    Required for Seaside
    SUnitPreload exception handling now actually works
  • The IBM Internet Connection API (ICAPI). ICAPI is a shared-library-based interface supported by the IBM Internet Connection Server and Lotus Go Webserver. The ICAPI interface has been identified as an obsolete feature. It is still shipped and supported in this version of VA Smalltalk, but may be removed in a future version.
    The Netscape Server API (NSAPI). NSAPI is supported by the Netscape Web server software. Instead of running stand-alone programs, NSAPI uses shared libraries to extend the server software's capabilities. The NSAPI interface has been identified as an obsolete feature. It is still shipped and supported in this version of VA Smalltalk, but may be removed in a future version.
