6 iSeries Access for Web V5R2 and WebSphere Host Publisher V4.0
Host Publisher server also includes components such as connection management, license
monitoring, runtime administration, XML Gateway, SSL support, and log and trace
management.
IBM WebSphere Host Publisher and IBM WebSphere Host Publisher Studio have been
bundled with iSeries Access for Web.
1.6.1 What is new in Host Publisher V4.0
Host Publisher Server on iSeries requires you to install WebSphere Application Server 4.0.2.
Advanced Edition or Advanced Single Server Edition. As part of the WebSphere V4.0
environment, the following main enhancements are made in Host Publisher:
J2EE application support: Applications produced by Host Publisher Studio comply with
J2EE, an industry-standard architecture that is intended to reduce the cost and complexity
of developing enterprise applications. A J2EE application takes the form of an Enterprise
Archive (.ear) file into which all the application's pages, Java objects, and resources are
assembled. Host Publisher applications on the server developed with an earlier version of
the product must be migrated to Version 4.0. A migration tool is provided.
JavaServer Pages (JSP) 1.1 support
: Host Publisher Studio now produces JSP pages
at the JSP 1.1 level. Applications with JSP 1.0 tags still run, but applications with JSP 0.91
tags (created prior to Host Publisher Version 3.5) need to be migrated. Two migration tools
are provided. One PC-based tool is supplied with Host Publisher Studio and another tool
is supplied on the server side.
Enterprise JavaBeans (EJB) 1.1 support
: Host Publisher now builds EJB-based
applications supporting the EJB 1.1 specification level. EJB access beans developed with
an earlier version of the product must be migrated to the 1.1 level; a migration tool is
provided as part of Host Publisher Studio.
Web Services: An application integration technology, based on open standards and
implemented in middleware, provides a way for applications to connect and interact on the
Web more easily and efficiently. Host Publisher Integration Objects and EJB access beans
are enabled to become Web Services.
Multi-language support
: Host Publisher multi-language support allows the Host
Publisher server to be administered in languages other than the server's default language.
Host Publisher documentation can also be viewed in multiple languages.
Serviceability
: The Software Maintenance Utility is
a new command-line tool that assists
in the application of software fixes.
WebSphere Portal Server 2.1 support: The Host Publisher portlet provides access to
Host Publisher applications. Legacy content can be included within the personalized
single point of access view delivered by enterprise portals.
Tooling: Host Publisher applications are imported into WebSphere Studio tooling (for
example, Application Developer 4.0.2/4.2.3).
1.7 Host Access products
