I need to implement an Image Map inside a Portlet. The user would click
on a certain region of the U.S. map, and then they would see that region
highlighted and they would also see the appropriate data for that region in a 
table next to the map.

The client has WebLogic Portal 8.x, so they're using J2EE 1.4. For
previous AJAX-related work, I've used client-side APIs like Prototype and
Scriptaculous to avoid any Java version compatibilities. Besides, I think this 
is strictly a client-side thing, so it's also about separation of concerns.

So, I have Prototype and Scriptaculous in place as a base AJAX Engine,
and I have a few other APIs on top of them to support tooltips, sortable
tables, and progress bars.

Getting back to the Image Map, here are my questions:
1) What are the basic steps in creating/developing an Image Map?

2) What's the best way to go about this?

3) Would it make sense to an Open Source Image Mapper tool to generate
the base HTML and JavaScript?

4) Could I use GWT? If so, would it cause compatibility problems with
Prototype and Scriptaculous?

5) How do I layer the images (basic U.S., U.S. with North East
highlighted, andso on)? What about the performance of loading all those images?

6) How do I create AJAX events based on the user's button clicks? I
don't want the page to flicker.

7) Have I missed anything?
8) Are there any books or articles I can read on this topic?

I'm just looking for an overall approach to the problem that works
within my architectural constraints.

Thanks for all your help.

assistance, however, please contact Mary Temple, Chris Maradie, Susan
McCarthy, or Nathan DePonte.

I have the same table in both a struts and a netui app.  The struts 1.8
table exports as expected, however, the netui will only export the
number of rows that display (based on pagesize setting).  If this has
happened to you do you have a work-around?

Workshop 9.2, DisplayTag 1.1.1
code
<display:table name="${results}" export="true" sort="list" uid="row"
pagesize="${pgsize}" requestURIcontext="false"
requestURI="${context}/usage.do" >

Nayeem,

I think this is what you are looking for. Add the following to the top
of your JSP file (uncommenting out the specific mimetype setting, of
course):

<%
      //"text/html" is implicit
      //response.setContentType("text/html");
      //response.setContentType("text/plain");
      //response.setContentType("text/xml");
      //response.setContentType("application/vnd.ms-excel");
      //response.setHeader("Content-Disposition", "attachment;
filename=foo.xls");
%>

The last line -- Content-Disposition -- is the hint to your browser
that you'd like to treat the response as an "attachment" instead of
something that should be rendered inline.

The "setContentType" is the MIMEType of the data -- do some research
on that to get the right data type for the content you are downloading.

Cheers,
s

Scott Davis

Howdy all,

I'm doing a talk at OSCON in July about Rails, Grails, GWT and Flex.
To prepare, I plan on developing an application with these
technologies and learning a lot about the various combinations. You
can read more about this on my blog:

http://raibledesigns.com/rd/entry/what_s_a_good_ria

I've gotten quite a few suggestions on the app I should develop.
Here's a post where I describe a survey I created.

http://raibledesigns.com/rd/entry/re_what_s_a_good

If you have 1 minute to fill out the survey, that'd be great.

Thanks!

Matt

Dear All,

I have a persistent set

@Entity
public class Group {
    @ManyToMany(fetch = FetchType.EAGER)
    @Fetch(SUBSELECT)
    private Set<ItemEntity> subTopics = new HashSet<ItemEntity>();
}

Problem:
- I save a Group.
- When I add an element "subTopic" of type ItemEntity (another
@Entity) to the set, it prints it in the toString() method (line 1
below) but claims it is not in the set.
-  When I remove it (using either group.getSubTopics().remove(topic)
or subTopics.remove(topic) syntax), it does not remove it. The group's
single element, though, has the same hashCode() and equals subTopic.

But...
- When I use an ArrayList instead of HashSet, everything works fine.
- Other persistent HashSets (written by some1 else...) do work for me.

What can I do to make it work with a Set? I really need a set here.

Here's the log:
group.subTopics = [[SUB_TOPIC] ID 4 V1 Computing with Angles
ItemEntityImpl]
WARN  ContentUserAssociationRemoverImpl -
group.subTopics.contains(subTopic) = false
WARN  ContentUserAssociationRemoverImpl - subTopic 2014616930
subTopic==subTopic? true
WARN  ContentUserAssociationRemoverImpl - element hashCode 2014616930
element==subTopic? true subTopic==element? true

Thank you so much in advance for your help,
Oren

The way to handle these situations is using security questions that you
gathered during registration. These registration emails are normally
just used to verify email addresses are real, so you usually don't need
to secure them too much as long as the email doesn't log the person in
(that's very important!). Next, if you are securing password reset
emails, just use one of the "What's your pet's name?" questions before
you allow them to change their password and you should be fine.

Question:

Does someone know how one would secure a self-registration emai so that
no one but the email recipient could use the confirmation link. Assume
a scenario such as:

1 A User registers at a site and enters their email.
2 The website creates an account for the user and sends them a
confirmation email with an https link back to the website to confirm
the registration.
3 The user recieves the email, clicks on the link and the user is taken
to a web page where they finish registration.

How is the email link secured so that someone else cannot intercept the
email and register under the user's account an essentially steel there
identity.

The JCatapult team is pleased to announce the release of 1.0-RC2.  For those unfamiliar with JCatapult, here is an overview:

JCatapult is an open source (ASLv2) application development platform targeted primarily at web applications, but capable of being used for most applications. JCatapult is built on top of well known open source tools including:

• Apache Ant
• Struts2
• Hibernate
• Guice
• FreeMarker
• Joda
• Many others

As a web application platform, JCatapult provides a truly lightweight method of writing and using services. By leveraging Guice for dependency injection you don't have to mess around with tons of XML files to wire your application together. In fact, JCatapult is based on the principle of discovering services. This means you write the services and JCatapult will find them.

One of the best features of JCatapult is its support for Modules. JCatapult Modules are full sets of functionality that can be plugged into any JCatapult web application. An example of a Module might be a fully functional Blog. Once added, JCatapult will discover the Module and your web application will inherit all its functionality.  In other words, users will be able to add, edit and manage blogs without you having to write a single line of code.  A number of commercial JCatapult Modules are already being written and more are in the works. The JCatapult team hopes to see a number of open source Modules start to appear in the near future.

JCatapult has a number of other services and tools it provides including:

• Scaffolding framework
• Deployment framework
• Database migrations
• Pluggable build system
• Dependency management (via Savant)
• Credit card services
• Email services
• And others

JCatapult is already in use in a number of websites and is stable. Head over to http://www.jcatapult.org and check it out.

Hello.

    I'm a Sun Certified Enterprise Architect.
    Every day I search the web for Java related items. Often the
results I get must be further filtered because the search engine
includes results from all sites it has in its index either related or
not to the java world.
    To alleviate this problem I thought to create this Google custom
search engine: www.jaaava.com.  It uses an internal list of sites I
carefully selected. I have included all online documentation of
popular open source projects and commercial products, all major Java
article sites, all major Java user forums and wiki knowledgebases,
blogs from well-known Java personalities, online Java APIs docs, Java
book excerpts and much more.
    I've also included some sites about technologies and languages
that a java professional is highly possible to use together with
Java: XML, HTML, Javascript, Ajax, design patterns, etc.
    I hope you'll find it useful too.

Best regards,
Felix Sima
