OpenDS is fast approaching version 1.2 (Release Candidate 2 was released late January) and Ludo has been sharing many tips for this release. Examples include: Troubleshooting OpenDS database, Disabling Schema checking, and Troubleshooting indexes and search performances.

New in OpenDS 1.2 are SVR4 package for integration into OpenSolaris (with SMF and RBAC support), a data and schema browser (Control Panel), SASL support, and increased performance over the 1.0 release. Another major version (2.0) is planned for later this year with Assured Mode as its key feature.

Sun Tech Tips are fairly short but effective articles focused on specific parts of an API. Specifically, Enterprise Java Technologies Tech Tips focus mainly on Java EE 5 and GlassFish features with code snippets for all of them. Java EE 5 Tech Tips are often written by the GlassFish developers themselves. The latest March issue covers Securing WebServices using WSIT and EJB Security Annotations.

Other recent tips covers EJB 3.0 Compatibility and Migration, Introduction to jMaki, Configuring JAX-WS Handlers on the Client, EJB 3.0 Interceptors, Document Handling Using JAX-WS Dispatch and Provider APIs, and more.
