New features in version 4.1
64 EAServer
Web services support
In EAServer 4.1, you can optionally install the Web Services Toolkit, which
provides support for industry-standard Web services protocols such as Simple
Object Access Protocol (SOAP), Web Services Description Language
(WSDL), and Uniform Description, Discovery, and Integration (UDDI). SOAP
provides a standard protocol for component invocations over HTTP
connections, for example, you can expose a purchasing component to be called
by business partners as a Web service. WSDL describes the service and can be
used in client applications. You can also publish business and service
information to a UDDI registry site on the Web and make your web service
available to other users. SOAP provides a platform and language neutral means
of accessing these services. With SOAP, WSDL, and UDDI, collaboration
between business partners is made easier because interfaces between
applications become standardized across disparate platforms.
The Web Services toolkit provides a Web application to run SOAP services,
and graphical user interfaces to configure the SOAP services, create WSDL
documents, and register services in UDDI registries.
For more information on these features, see the Web Services Toolkit User’s
Guide.
Message Bridge for Java™
EAServer 4.1 includes Message Bridge for Java, a powerful, easy-to-use tool
you can use to build applications that generate and consume documents and
messages. Message Bridge generates Java classes that simplify the parsing and
construction of XML documents. For more information, see the Message
Bridge for Java™ User’s Guide.
Deployment enhancements
EAServer 4.1 has new features to simplify the deployment of applications to
EAServer:
• When using Jaguar JAR format archives to deploy between EAServer
installations, you can include merge files. A merge file allows you to
modify or delete settings for entities that already exist. For example, you
can create a merge file to install a package into the Jaguar server, without
affecting the list of packages that are already installed.
