Hi,

I've a requirement wherein i want to disallow the portlets to resized ... ie not to allow users either to maximize or minimize it. Also, there will be a title for the portlet that will be displayed at the left corner of the protlet window. I don't want that as well.

How can i achieve the above in jetspeed portal?

Any help is highly appreciated.

Thank you.

I'm developing a social networking portal using spring framework.

I have the following requirement.

A user who is willing to join this social networking portal will fill up a online form and clicks 'Submit' button. Upon clicking submit button, i need to send an email to the email id provided during registration with a link to visit. Once user sees the email, he visits the link provided and then user account is created with data provided during registration.

Now my problem is i'm unable to come with some web link that i can provide in the email upon registration.

How to form a link with user data provided in a portlet?

Where should i keep that registration data (in session or ???)

I'm not clear on how to implement this logic. Can anybody give me insight on how to implement the above mentioned logic?

Any help will be highly appreciated.

Thank you.

Well .... if you create a web project, it gives you only web.xml. For a portlet project, we need protlet.xml file. And also a build file that created a war file which can be deployed to any portal server.

How do i get those files in a web project?

Is there any other way of doing it? PLease suggest.

Hi Ranchers,

I installed JSR168 and JSR286 plugins for portal development for eclipse using 'software updates' option wherein i give the url 'http://portlet-eclipse.sourceforge.net/update' in the Add Site option. I installed the plugin. But the project tab doesn't show any portal project type.

If i see in 'WIndows -> Preferences' option, it will show portlet.

My requirement is to create a portal project in eclipse that supports spring framework.

Can anybody help me in successfully create a portal project in eclipse?

I'm using jetspeed 2.1.3 as the portal server.

Thanks in advance for any help in this regard.

I'm using maven 2.0.9 on linux m/c. I would like to create a portal project that should run on jetspeed 2.1.3 portal server. I'm using spring framework 2.5.5 as the framework.

I'm using eclipse IDE (ganymede).

Since eclipse doesn't provide any option to create a portal project, i thought whether maven can help.

Somehow i want to create a portal project that i can import it to eclipse and later deploy it on jetspeed.

PLease help. I'm spending almost three complete days in the net searching for how to achieve the above with no results.

Thank you so much for any help in this regard.

Thanks again.

I'm going to develop a portal application from scratch.

I'm on linux m/c with jetspeed2.1.3 as portal server and eclipse 3.4 (ganymede) as the IDE with spring framework version 2.5.5.

I know how to write spring code. But don't know how to create a spring portal project in eclipse. I've installed all necessary plugin for eclipse (subclipse, DLTK, WTP, M2ECLIPSE, MYLYN, AJDT etc). BUt the project explorer doesn't show any tab for portal.

I'm I missing something here? ANy extra plugins required?

Basically i want to create a spring portal project thro' eclipse or by any other means so that i can kick start my project implementation.

ANy help in this regard is highly appreciated. Thank you.

After studying on both the technologies, we chose Spring framework for the portal development.

Does anybody have any idea how to setup jetspeed and ant with eclipse?

I would like to automate the process of building and deploying portal application with eclipse and ant on linux platform.

If anybody know any good resources any book that best explains these things, please pass the information.

Thanks.

I would like to know how to deploy sample spring application on jetspeed2? What are the steps involved etc.

Also, i would like to integrate jetspeed with eclipse so that i can automate build and deployment process in linux environment. I didn't find much written on this on the net which is helpful to me. Is there any plug-in involved or in the first place will eclipse supports jetspeed?

Any help in this regard is highly appreciated.

Thank you.

Well .... to give more about the requirements, below are the ones:

1. Portal Administration (add/remove portlets etc)
2. Multilanguage support
3. Multiple markup support (html/wml etc)
4. Multiple device support (standard browsers / cell phones etc)
5. Creation and management of social groups
6. Search functionality (searching friends within the portal - which requires caching)
7. Personal Mailbox
8. Upload images/ videos and tag them
9. Share media (files/images/videos) among the members of a social group
10. Event handling (shared calendar events - menas if one person entered a event in the calendar, members in his social group can see that event)
11. Inviting friends
12. Logging & tracing (technical side)
13. Deployment of such an application
14. May be customization / personalization
15. Registration & login
16. Authentication & authorization
17. Security

etc.

We have already decided on the platform and below are the softwares we chose:

1. Linux OS
2. MySQL 5 as RDBMS
3. Jetspeed 2 as portal server
4. Tomcat 5.5.23 as app server
5. ant1.7.1 as build tool
6. Eclipse as the IDE

For the above specification, which framework you suggest?

Thanks in advance.

We are in the process of developing a social networking portal similar to facebook / myspace. We are looking for best framework which suits the application.

We are going to choose one among Struts 2 or Spring. Can anybody suggest which one will be better?

Any suggestion in this regard is highly appreciated.

Thank you.
