iPOV has posted jSai 0.7, an open source (Apache license) Servlet Authentication Implementation. based on J2SE + servlets. A J2EE application server is not required. jSai supports basic JDBC and XML backed user stores, as well as an LDAP user store. According to iPOV,
While there are several attempts to create authentication and authorization standards for J2EE applications, they tend to be overly complex; and more importantly have little support for providing information to an application. For instance, the security constraints specified for Servlet Containers allow security mappings that are potentially quite rich; but the only security information provided to a running servlet application is request.getUserPrincipal() and request.isUserInRole() - so in order to display menus based on user privalages the servlet/JSP writer needs to know the mapping of rolenames and users to security levels. Wounldn't it be much more logical to have a way to proactively check to see if a user will be able to access a web resource without needing to know the runtime configuration, a canAccess(user, url) method as it were? We think so. This enables system administrators to change security settings without needing to re-code application logic. You no longer need to choose between displaying a link to a site section that many users would not be authorized to view, or hardcoding in the restriction parameters.
jSai is implemented as a servlet Filter, a set of JSP Tags, and a supporting library (for servlets). Users, and group information can be stored in XML files, a JDBC accessable databases, or in LDAP. The JSP Tags as well as library calls enable web application developers to access important authentication information.
Rob Lougher has releeased JamVM 1.1.4, a free (GPL) Java Virtual Machine that "conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~100K, and Intel 80K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, the Java Native Interface (JNI) and the Reflection API." Like most free VMs it relies on the Gnu Classpath library whic is upgraded to 0.0.9 in this release. 1.1.4 also adds the JNI enhancements introduced in Java 1.2. JamVM only interprets code. It does not have a Just-In-Time compiler.
