Consider the following code. Why is the first while loop result in an infinite loop? It seems that list.iterator().hashCode() gives me a different code/iterator every single time. Does anyone know why?

It has 2 gb of ram xeon 1.87 cpu running winxp.
I was recently forced to start using IBM RAD (rational application developer) due to corporate policy. I found it extremely slow and I am wondering if there is something wrong with it? I used eclipse and jboss before and although it wasn't lighting fast, it is at least acceptable. Are there any settings that I should check?
I heard this phrase a few times from tv when high level managements talk about their enterprise software system but I am not sure what it means, does anyone know? For example, there was a time when the phrase was used as "our tool... provides a holistic view of all the parties involved.. " what does that mean?

Can I have both input and output stream active on the same file? Basically my program adds files to a jar, but if the file already exist inside then I will skip adding.

I have a program that adds files to a jar file using JarOutputStream.putNextEntry(myJarEntry).

I keep getting the following error.

java.util.zip.ZipException: duplicate entry

Besides keeping a list of files added to the jar, is there a better way to tell if a file with the same name already exist in the jar file? I tried File.list() but it returns null. Thanks!

I am reading the syntax from: http://www.blooberry.com/indexdot/html/tagpages/d/doctype.htm

which states the DOCTYPE syntax as follows:

<!DOCTYPE [Top Element] [Availability] "[Registration]//[Organization]//[Type] [Label]//[Language]" "[URL]">

When reading one of the sample q&a from an xml mock test, it states that the following is syntactically valid, which conflicts with the above syntax. So who is right?

<!DOCTYPE name PUBLIC "fileName.dtd" "http://"; >
Hi, I am just reading the ibm tutorial that it states that:

"After applying an XSLT stylehseet to an XML document, the output is always another XML document."

I don't quite understand why the above statement is correct. I believe the XSL processor takes an XML document as input and transforms it (by applying XSLT stylesheet) to a format such as HTML. Perhaps my understanding is incorrect?

Hi, I am just reading a tutorial on DTD and it mentioned about there are two ways to reference an external DTD file within an XML file - public identifier and system identifier. It further says public identifier is location independent, what exactly does it mean?
How much time did you spend preparing for SCDJWS exam and what sort of background do you have? Thanks!
Hello, I only find a 3 part tutorial at the ibm site and it was written in 2005. Is it still useful?

Is there a parameter to specify which page to display after a session timeout on websphere 5.1. I could not seem to locate such a parameter. I am aware that weblogic has such a parameter so I would assume it also exist in websphere.

I have been away from coding in the past 1-2 years. I am wondering what are the most in demand skills in the job market? Are spring and struct still popular? Any help is appreciated.
