Resin plugin for Eclipse

Since I'm starting to learn more about Resin, I went searching for a Resin Plugin for Eclipse. I found ResinLauncher at improve-technologies.com. Trying it now with Resin 3.0.0 Beta.

Update: That plugin sucks, and I couldn't find any from my favorite plugins site that just worked. Maybe with a little more effort, but I don't have the patience. If anyone knows of a plugin that works as nice as the Tomcat Launcher, let me know. I think the Tomcat one b/c I don't really have to setup my project to be a "Tomcat Project", but rather I can simply run Tomcat in Eclipse and set breakpoints and such.

How do I remove duplicates in a List?

I have a List that may contain duplicates and I need to filter out the duplicates (so I don't get a foreign key violation when inserting records). Are there any Jakarta' Commons utilities to do this? I can see a few solutions to my problem:

  • Present it on the UI. This might be tough since I'm using a select box JavaScript library. Hmmm, I am using a custom setter for the String[] that gets sent in, maybe I can do it there - checking to see if the ArrayList I'm setting already contains the given String.
  • Filter it out in the business layer.
  • Use a type of List that doesn't allow duplicates, and just ignores a duplicate value when you try to add it.

I just thought of #1 while writing this post. It's cool how talking about your problems can help solve them - no wonder shrinks get paid so much. I'm still interested in any proposed utility classes.

Struts-JSF Demo

I've setup another demo - this time it's the struts-example app ported to use JSF and Struts. Nothing ground breaking here that I can tell, and after looking at the code, I don't know what to think of JSF. It seems to make it much harder to code a JSP page.

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core" %>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html" %>
<%@ taglib prefix="s" uri="http://jakarta.apache.org/struts/tags-faces" %>

<f:use_faces>
<s:html locale="true">
<head>
  <title><
    <s:message key="registration.title.edit"/>
    </title>
  <s:base/>
  <s:stylesheet path="/stylesheet.css"/>
</head>
<body bgcolor="white">

<s:errors/>

<s:form action="/saveRegistration" focus="username"
         onsubmit="return validateRegistrationForm(this);">

  <h:input_hidden id="action" modelReference="registrationForm.action"/>

  <h:panel_grid
           columns="2"
        panelClass="form-background"
       headerClass="form-header"
     columnClasses="form-prompt,form-field">
.
.
.

Ugh, a whole new set of Tag Libraries to learn? Seems like JSF is a lot of bloat, while JSP 2.0 has been made things simpler. One interesting thing is the use of the single-letter (i.e. "h", "s") for the tag libraries. I suggested this a while ago on the struts-dev list, and it looks like it's been implemented. Bravo! I doubt I'm the reason for it, but it's always nice to see your ideas implemented.

I apologize that this site was down most of the day today. It seems that the monitoring/restarting scripts were not running and this should/will be fixed shortly. I need a gig where I can restart this site when it goes down. Anyone know of a way to telnet/ssh via an HTTP Proxy?

Russell: Here's your hookup

The Butt Ugly Weblog (Scaring little kids since 2003) has offered Russ some love. Since I like Russ, here's your hookup baby!

Russell Beattie wants to be #1 Russell.

Since he's a good guy and posts and discovers an insane amount of interesting stuff, I've gotta help him :-). Google, here you go!

To Janne Jalkanen: I dig the name of your blog, I LOL'ed when I first read the title. Also, you're Finnish, so that means you've got to be cool. My Grandparents (last name: Hill) were Finnish and I'm about 35%; the rest being German, Dutch and Irish.

Camino 0.7 Released

Camino™ (formerly Chimera) 0.7 is available for download. Along with the new name, Camino has a new history sidebar, a new download manager and a new text encoding menu. To learn more about what's new in Camino 0.7, check out the release notes

Damn, with all of these great standards-compliant browsers for OS X, I need a Bookmark Manager so I can share bookmarks between them all. Anyone know of one?

[ANNOUNCE] Struts-JavaServer Faces Integration Library -- Early Access Version Now Available

I'm happy to announce the immediate availability of an integration library
that allows you to use the recently published EA3 release of JavaServer
Faces with a recent Struts build (nightly build 20030216 or later, or 
the upcoming 1.1-rc2 or finalrelease).  Nightly builds of this package are 
available at:

 http://jakarta.apache.org/builds/jakarta-struts/nightly/struts-faces/

The sources for this package are in the  "contrib/struts-faces"
subdirectory of the  "jakarta-struts" CVS repository.

You should take note of the following important points:

* The design goal of this library was to allow Struts application
 developers to migrate the view tier of their applications from the
 existing Struts tags, to pages that use corresponding JavaServer Faces
 component tags, with no changes to the corresponding business logic.
 This goal has been substantially achieved for simple applications
 so far; additional work will be necessary for more advanced apps.
 As a proof of concept, the JavaServer Faces based version of the
 canonical  "struts-example" web application is included in the
 distribution, so that you can see for yourself how little had to be
 changed.

* The integration library has been tested under Tomcat 4.1.18 and
 the Java Web Services Developer Pack (version 1.0_01), although in
 principle it should run on any Servlet 2.3/JSP 1.2 container.
 (It will not run on Servlet 2.2/JSP 1.1 containers).

* There is a known issue when trying to run JavaServer Faces EA3
 under the recently released Java Web Services Developer Pack
 (version 1.1).  Watch the JavaServer Faces web page (at the URL
 listed above) for up-to-date information on workarounds.

* The JavaServer Faces distribution is an EA release, not suitable for
 use in production environments.  In addition, the license terms
 under which it can be downloaded prohibit redistribution.  Therefore,
 you will need to download your own copy of JavaServer Faces EA3 and
 integrate it with the example application before it can be deployed.

* The integration library should also be considered to be of alpha
 quality, not suitable for production use.  There are a set of known
 issues and limitations at the bottom of the README.txt file.  Please
 file bugs against this package in the usual Bugzilla location:

   http://nagoya.apache.org/bugzilla/

* For generic questions about JavaServer Faces (i.e. not related to this
 integration library), your best resource is the JavaServer Faces forum
 (free registration required) at:

   http://forum.java.sun.com/forum.jsp?forum=427

See the README.txt file in the top-level subdirectory for more information
about installing and using this release.

Struts and JSF - Sample app is on its way!

Craig McClanahan just sent the following message to the struts-dev mailing list after creating a new struts-faces directory (and sub-directories in Struts' CVS tree.

Yep ... it's here ... the promised integration library that lets you use the recently published EA3 release of JavaServer Faces with a recent Struts 1.1 build (see the README.txt for details). Unfortunately, the CVS commit for the actual code was too big for the mailing list -- essentially, it's all the files in the "contrib/struts-faces" subdirectory.

My plan is to publish nightly builds of this code (it's EA quality) but *not* to incorporate it into any formal 1.1 release. More info in an announcement message to come shortly.

Craig

You and I both know the best way to learn JSF (and JSP 2.0) is to start using it on a project. Whether it's your own, an open source project, or a paid project - it's truly the fastest way to enlightenment. I was lucky in my quest to learn Hibernate - I had two concurrent projects (struts-resume and paid) using it.

As far as computers are concerned, I've had a pretty bad day. After writing a long e-mail (about as long as this post), I kicked back in my chair to hit send and kicked the power cord out of the socket! Doh! This actually happens about once a day, but usually I'm coding and testing and I'm saving every 30 seconds. Secondly, I had this post all written and formatted about 10 minutes ago, and Phoenix crashed when I switched tabs to copy/paste something. Damn thing - it's been crashing a lot lately. It might be time to revert back to IE (am now) or Mozilla.

How do you initialize Hibernate?

If you're using Hibernate in a servlet container, then you're probably using a hibernate.cfg.xml file to configure Hibernate and talk to your JNDI database connection. If you're not, you might want to consider it. My question is, where do you initialize Hibernate? In version 1.2.3, you call Hibernate.configure() to do this, and everything will startup and be ready - providing that hibernate.cfg.xml is in your classpath (WEB-INF/classes).

// Configure Hibernate.
try {
    Hibernate.configure();
    if (log.isDebugEnabled()) {
        log.debug("Hibernate configuration completed...");
    }
} catch (HibernateException h) {
    h.printStackTrace();
    throw new UnavailableException("Error configuring Hibernate: " + h.getMessage());
}

I've been using a StartupServlet that is set to load first, and is also responsible for putting drop-down options into the application scope. However, it has recently come to my attention that I could easily use a ServletContextListener and initialize it (and my drop-downs) in the contextInitialized() method.

So my question is - which is better? From what I can tell, they do the same thing and I've never had any issues with the StartupServlet. Can anyone offer some pros/cons to each approach? Which do you use?

Java Server Faces Demos!

Dave points out that there's a new Java Server Faces spec available.

The Server Side also reports that Sun has released Java Server Faces (JSF) Early Access 3, a tutorial, and a public draft of the JSF spec.

If you're like me, you just care about the code and how it looks. So I've taken the five war's that are distributed with this release and installed them on this site. If I get too many OutOfMemory errors, I'll remove them - but hopefully they can stay up for a day or two.

MoPhoto'd

Well, I went ahead and ordered the Communicam from AT&T and it should be hear in 3 days or so. Julie thinks I'm crazy, and she's probably right that the camera sucks, but I want to be a moblogger. I want to post pictures and blog, in real time. My first adventure? I hope to mophoto Erik at the Denver JUG meeting a week from today. That is, if I get the camera and figure it out in time.
