Sun Microsystems on Wednesday released the second beta of Java 6, the company's next-generation development language targeted at so-called Web 2.0 programmers. Perhaps most enticing for those new to Java, the update adds a framework for supporting popular scripting languages such as PHP.

Java SE 6 -- previously known by the code-name "Mustang" -- also leverages JavaScript and includes a full "Web services client stack," along with support for recent Web services specifications like JAX-WS 2.0 and JAXB 2.0. In addition, the release will bring support for Windows Vista.
