"alfred",
we require real display names here at the Ranch, please see the warning here.

Please edit your profile and correct this immediately, since accounts with invalid display names get deleted, often without warning.

thanks,
Dave

THIRD AND FINAL WARNING

Alfred, you have been asked repeatedly to change your display name to show your real first and real last names, but you have ignored them.

This is your last warning before your account will be deleted.

I suggest you change it now.

I will give you two days from the date and time of this post.

No, i have seen the message and i have respect on you. i dont want to put my full name. dont you give the freedom,privacy to the poster ? everytime name,name and name! its quite annoying.Not only me but other posters too. whats the matter with just a "name" man ? why you are attacking ? is it so important rather than a java/J2ee question ?


is this name bad ? You have a naming policy. ok,good.dont you think , this name seems like a human being ? is not it enough to recognise a person ?
its really ridiculas.


OK, tell me a "name" of your choice which will satisfy you.i'll use that next time. probabily that will satisfy you.


if you think that i am protesting against your comment, so you want to suppress me , go ahead, delete account. but to me "name" makes sense.

Names only have to look real. Mine's not.

i agree. do you think "alfred" could be name of a dog,cow,goat but not of a human?

anyway, i want to leave this matter here and want to come back to my question.
actually i could not understand those differences between portlet ,servlet. Its difficult. it may be simple to you but not to me.

can you please explain a little bit ?
thank you.

A lot of the people who agree with the policies here and like the way this site is run will abstain from participating in threads if the starter has unresolved issues with the moderators.
In other words, the quickest way to leave the matter here is to go and fix your display name.

-Thanks

Sorry, no.

Compliance with the naming policy is a condition of using this site. If you cannot comply your account will be closed.

There are a number of ways that people protect their privacy on the site, but the simplest solution is: If we can't be sure it's fake we'll accept it. Alfred Jones, Alfred Smith, Alfred Thomas would all be accepted, Alfred Hitchcock would not (it's obviously fictitious.)

I'll give you one day to fix your display name, then I'll have to ask for your account to be closed. Feel free to comment in the JavaRanch forum, but we've discussed the naming rules may times and you'll just be asked to read a previous conversation.

thanks,
Dave.

I was hoping to find an answer to the thread starter's question after the "name" controversy had been resolved.

Actually, Portlets still use JSP/Servlets. They are just mini applications, to put it simply. When you go to a Portal there will be multiple mini applications called Portlets.

Taken from "Creating Web Portals with Bea Weblogic" from Apress publishing by Howard Block, Rob Castle, and David Hritz


Portals can be classified into the following types:

Internet public or mega portals - like Yahoo, MSN, AOL

Intranet corporate or enterprise portals - designed around business processes like payroll, human resourse, etc.

Extranet e-business portals - business to consumer like an Amazon.com

A portlet is the component within a portal that gives the portal functionality.


So for instance, a portlet for Yahoo could be their search engine, e-mail, maps. All those links you see on Yahoo lead to a portlet.

Hope that helps

And thank you for changing your display name. I personally would prefer your real last name. Using real names makes this site more personable. No hiding behind aliases. this is a public place and no need to hide identities or want to. Plus, as you are here more and answering questions you actually get your name out and become recognized. I have reaped huge benefits from this community using my real name.

I am sure there are plenty. But I wouldn't be able to name them since I don't work for any of them. Meaning I don't know who they are. Actually I think companies like pacificare's website is probably portlets because I know they were hiring Java people. and Pacificare would be the perfect company to use them. I also know that Ebay uses Java, so that is probably a portal with portlets.
