Could someone give me an example of the best way to add an iterator to a custom class pre Java 5's iterable interface? Would wrapping a Collection be the best option? Something like public Iterator iterator() { return wrappedCollection.iterator(); } In my initial post I confused Iterator with Iterable. The end result I am interes...
What is the easiest way to find the Struts library version? I'm adding Struts libraries to an generic eclipse project, and need to be able to differentiate between versions. (Other libraries like Spring have a getVersion() call) I can always read the jar manifest, but I'm looking for an easier way. ...
I've used Tiles and Sitemesh for a number of years and while I personally prefer the Sitemesh style page decoration, I generally don't see a lot of mention of Sitemesh or Tiles on the Internet. Do people use Tiles and/or Sitemesh actively, or are there other libraries that have taken over in this capacity? ...

I have a Struts portlet being used in a Liferay Portal environment. I have been localizing my resource strings using standard resource files so far. I can access the message bundle from my portlet using the <bean:message> tag, and it works great. So for example, in a form I might have the following label defined in my JSP file. ... <lab...

When you have multiple projects that all use the same set of JAR libraries, it's tedious to include the same JARs over and over again with each project. If I'm working on 20 different projects, I'd rather not have 20 of the same exact set of JAR files lying around. What's the best way to make all those projects (and new projects as well)...
Hi all, I need to create form that will be filled in by hand and read digitally. I plan on using a sort of scantron-esque format with rows and columns that the user can just color in the a circle in the appropriate cell and the computer will know that value based on the xy position in the cell matrix. Like an excel address. | S...
I am trying to use the (flash based) YUI Uploader with a Java (Spring-based) back-end. The typical way of uploading files in the Java Servlet world is to set the ENCTYPE='multipart/form-data' on the HTML form requesting the file from the user. With the right server side APIs (i.e. Commons FileUpload), it is possible to get the file on t...

I have an existing (java) application that models an order book, as it stands each order is visible to every other. There is now a requirement to put (what is effectively) a per order ACL in place. An example to illustrate, lets say I have access groups [V-Z] and orders [A-F] A B C D E F V 1 0 0 1 1 0 W 0 1 1 0 0 1 X ...
I'm trying to parse a WSDL file which is in another server but has hard codded "localhost" all over the document. When I fetch it, obviously the program complains "connection refused" because nothing is running in my machine.

When we release projects it is usually the same every time. Are there any arguments or properties that I can add to release:prepare that will allow for pattern releasing in batch mode? Example: What is the release version for "MyProject"? (company.jar.site:myproject) 0.0.1: : What is SCM release tag or label for "MyProject"? (company...
