New features in version 4.2.1
EAServer 4.2.1 supports these new features:
• Web application form login enhancements
• EJB pass-by-reference support
• Database set-proxy support for EJB CMP entity beans
• SSL connection troubleshooting enhancement
Web application form login enhancements
EAServer 4.2.1 adds support for direct form login, which allows you to access
a Web application’s protected content directly, without requiring the user to
visit the Web application’s form login page. For more information, see “Web
application direct form login” in Chapter 3, “Using Web Application
Security,” in the EAServer Security Administration and Programming Guide.
EJB pass-by-reference support
EAServer 4.2.1 adds support for the proprietary EJB pass-by-reference
mechanism supported by some other J2EE vendors. For more information, see
“Optimizing in-server EJB calls” in
Chapter 3, “Component Tuning,” in the
EAServer Performance and Tuning Guide. This feature is not intended for new
development, which should use standard EJB 2.0 local interfaces.
Database set-proxy support for EJB CMP entity beans
EAServer 4.2.1 adds a new property for connection caches, to be set if the
cache is used by an EJB CMP entity beans and the cache has set-proxy support
enabled. The
com.sybase.jaguar.conncache.ssa.systemid property specifies an
alternate user name to set proxy to.
In an EJB CMP entity bean, the client user name is not available to set proxy
to since the persistence engine runs as the system user. In this case, if a user
name is specified with this property, the cache manager sets proxy to the
specified user. Otherwise, it sets proxy to the cache’s User Name.
