Java API for XML Web Services Addressing (JAX-WSA)

The Java API for XML Web Services Addressing (JAX-WSA) is a new component in Project GlassFish. It provides an implementation of the WS-Addressing specification, currently under development at the World Wide Web Consortium. JAX-WSA is also a part of Project Tango, Sun Microsystem's Web Services Interoperability Technology.

The JAX-WSA component is an EA release designed to give Web services developers a first look at this new technology in the Java WSDP. It is experimental in that it relies on a somewhat different line of code for JAX-WS than is installed by default with the open-source Java EE 5-compliant application server in Project GlassFish.

Users should note that the JAX-WSA component is not installed by default but requires a custom installation. Please see the installation instructions below for more information.

JAX-WS is now an open-source project at java.net! Check it out, join in, and make your contribution to this vital technology.

why the Java Vector class is called a "Vector"?

"Vector" is a common name for an array of one dimension.
I think that it was designed to be accessed in only one direction - from start to end. Of course, you can write code to iterate backwards...
But the enumeration it goes you don't have a getPrev() method, only a getNext():
for (Enumeration e = v.elements() ;
e.hasMoreElements() {
System.out.println(e.nextElement());
}
So a Vector has dimension (number of elements) and direction (in terms of access).

Is it possible to update the version of java automatically like antivirus?

Yes, If u install latest version of java 1.4.2_01 and later. java updated is new features of SDK/JRE.Its purpose is to provide the latest version of java in flexible way

Why String class is immutable?

JVM internally maintains the "String Pool". To achive the memoryefficiency, JVM will refer the String object from pool. It will notcreate the new String objects. So, whenevr you create a new stringliteral, JVM will check in the pool whether it already exists or not.If already present in the pool, just give the reference to the sameobject or create the new object in the pool. There will be manyreferences point to the same String objects, if someone changes thevalue, it will affect all the references. So, sun decided to make itimmutable.
