Hello Ashish,

I've got some Roo minded questions for you:

1) How does Roo scaffolding basically work? What goes on behind the scenes when I create a domain model class with some properties?

2) Domain driven scaffolding is awesome. But technological evolution goes fast. So I wonder which technologies (e.g. AspectJ) must I comprehend to further extend Roo using new technologies?

3) How would I generally go about creating a Roo addon? What steps should I undertake?

Thanks a lot in advance,

Hi all,

I installed apache2 and use mod_proxy to put tomcat7 behind it.

Now I want to enable https connections to Tomcat.

I already enabled the Tomcat ssl connector on port 8443.
But what steps I should take to make apache let tomcat handle ssl connections?

Could find a decent article online explaining this so I hope somebody in here can help.

Thanks a lot in advance and best wishes,

Jochen

EDIT: or perhaps is it better practice to let apache2 handle the SSL connections? but how would that work?

Hi all,

What is your favorite JSF implementation?

Imho PrimeFaces seems to have an edge since it uses jQuery and has jQuery mobile implementation.
What is your opinion on this? Any other implementations you would recommend?

Thanks and best wishes,

Jochen

ps: can't we post a poll on the forums?

Thanks a lot everybody for the replies.

I indeed agree you can't generate an application via UML but it does help you get started faster coding the business models I think.

Are there any well known tools that are worht mentioning?

I tried MyEclipse and it was ok. But perhaps there's a lot of better gear around?

Thanks and kind regards,

Jochen
Hi all,

I was wondering if it's good practise to generate Java and/or sql from UML?
Do you do things like this? What tools can you recommend?

Basically by moddeling your UML the whole Hibernate/Jpa/Java/sql stuff could be automated I guess.



What I've done so far concerning this is drawing something UML like (DB structure) with MySql workbench...forward engineering my DB.
Then in MyEclipse I've generated the whole Java code. Which I didn't use completely but I copy pasted lots of the code in my manually written DAO code.

But maybe there are better workflows around concerning this? Perhaps with full roundtrips so everything gets updated? (ok ok, maybe I'm just dreaming here )

Any thought or comments on this more then welcome!

Kind regards,

Jochen

Y3K seems pretty futuristic to me! Must be really awesome to live in Curacao. You think there are still a lot of jobs open for Dutch speaking J2EE developers?

You could create it yourself with under each h:graphicImage to display image and t:dataList to iterate over images.



Thanks for the help. I think so too it might be a good idea to create one myself.

I already found an existing open source project with admin section which I might modify to use a jsf front end:
http://sourceforge.net/projects/triarcticphoto

Greets,

Jochen

btw / ps: Interesting and futuristic blog you have, added myself as a follower.

Bauke Scholtz wrote:Your question is too general and vague. What exactly is your interpretation of "image gallery"?



Sorry, I will try to explain a bit better.

What I'm actually looking for is a way to allow the users of my website/webapp to create galleries and upload images in their galleries.
Something like the PHP image gallery "coppermine" does but of course running in a Java environment and it doens't need to have all those special features.

I realise that the chance of finding a JSF based package for this might be slim but if someone would be able to point me to some jsf components which could help me building my own little coppermine version, that would also be appreciated a lot. An open source non JSF (but Java based!) solution would also be great of course.

I hope this explains better what I'm looking for.

Thanks and greets,

Jochen

EDIT: ps: I've already browsed through sourceforge a bit but haven't found anything good yet.

Hi all,

I'm working on a webapp with a (Spring) Faces front-end.
Now I would like to include an image gallery.

Someone in here knows where I could find an open source java based gallery?
I already browsed sourceforge a little bit but until now, I haven't found a really nice one there.

All comments welcome.
Thanks in advance & kind regards,

Or perhaps it's peace of cake with some existing jsf components for me to build one?

Hello all,

I'm having a problem with the JSF form action.

My spring controller is mapped to /users/form.html GET and POST requests:



But JSF generates an action to "/www.appletree.be/WEB-INF/views/en_GB/users/form.html":



So my controller doesn't pick up the action of the form.

If I use firebug to change the action (in firefox) to /users/form.html the action does get picked up as it should by my controller.

I'm using Spring Web Flow btw to my flow handling but I guess this hasn't got anything to do with my issue.

All tips more than welcome since I'm a bit lost here!

Thanks in advance and have a nice day!

Hi all,

I was wondering if there is an easy way of adding/removing CSS includes in your html head when using the ui composition features of facelets?

Because often when using facelets composition you include something in your html body which also needs additional css. And perhaps it would be best not to load a lot of unnecessary css files from your html head.

All comments welcome!

Kind regards,

Hi all,

Has anybody ever tried OSGI in Tomcat?

It seems possible with the "bridgeservlet" I've read somewhere.

All comments welcome and thanks in advance!

Good point. I guess I better just keep on developing instead of doing proactive problem resolving based on some blog articles. After all if you have a well designed app you can switch technologies in no time.

Thanks a lot for the fast reply.
Have a nice weekend!

Hi all,

As I'm quite new to front-end design and I'm building a webapp (spring 3 based) from scratch, I've read serveral times JSP can be quite slow.

Would there be a better (read: faster) solution?

JSF/facelets seems interesting so I wonder if this is faster than plain old JSP?

Thanks in advance!
All info appreciated a lot.
