End of Year 2013 – What’s coming up 2014

Aside

The year 2013 is fast approaching its end. It was an extremely busy year for me, a couple of new projects needed my attention, other projects were finished (successful :)).

The German ADF Community (https://www.xing.com/net/adfcomm or https://twitter.com/ADFCommunityDE) opened from a partner community to everybody interested in sharing experience using ADF in all kind of projects. We had a well visited Hackers Event in January, the one day DOAG 2013 Development event in June, and the DOAG Conference in November and not to mention the ADF News Session, which are now called ADF Spot Light Sessions.

In Germany the ADF Community is growing and we are getting more and more interesting content and discussions. The ADF-EMG also gets more attention. Jack Flack is the new group moderator and doing his job very well, good luck John. We have to thank Chris Muir who did a great job as moderator of the ADF-EMG group.
The ADF G+ group Oracle JDeveloper, ADF & ADF Mobile was introduced late 2012 and has currently 982 (time of writing) members! Very impressive!
New members are welcome!

On the JDeveloper front we finally got the long awaited 12c version. It’s still not the big new version which has all parts (Mobile, SOA, BPM, …) in one IDE, but this will hopefully come soon. From the number of bugs found in the 12.1.2.0 version it’s not too bad that we have to wait for the 12.1.3.0 as this version has some of the nasty bugs fixed (https://java.net/jira/browse/ADFEMG).

So, what is to expect 2014?

The DOAG and the German ADF Community cater an ADF Bar Camp directly followed by an ADF Fitness Center.
The one day DOAG 2014 Development will be in Düsseldorf this year, a new attractive location which can easily be reached.

Do we see a new ADF Mobile version? New SOA? New BPM? New JDeveloper?
I think so, can’t be too long…

A final note on the OTN JDeveloper and ADF Forum:
I don’t know what Oracle is doing here. A big multinational corporation is not capable to come up with a working forum software. We all knew the old software could not be changed and had its bugs and breakdowns.
However, after installing the new software it we soon learned: new doesn’t mean better!
The users of the forum, or ‘space’ as it’s called nowadays, don’t get any information until they have found out themselves. No official statement (most of the time) on the things which have changes. This reminds me on the projects I participated which went very very wrong.
I hope Larry E. decides that not only the US Health Care needs help (is their web page running?), but the forum needs help from his best consultants too.

Wish you all a great and happy new year 2014!

DOAG 2013

Aside

I’m on my way to #DOAG2013 in Nürnberg, Germany, right now and have time to write this short blog about the next couple of days at DOAG in Nürnberg.

The final touches on the demos for my sessions are done 🙂

If you are attending #DOAG2013 please visit my session about using dynamic pivot tables on Tuesday, 19th, 10 am and my other session on implementing a big application using the pillar architecture on Tuesday, 19th, 3 pm.

In the meantime you may want to visit the German ADF Community also Tuesday 19th 2pm right on the #DOAG2013 ground. To make the day a real productive one finish with attending the Forms and ADF Expert Panel Tuesday, 19th, 5pm. Here you can gather useful information and ask questions directly to experts (and product managers which I assume are experts).

Wednesday is the day of ADF Mobile, at least for me. Let’s see how ADF Mobile has developed since last year. I couldn’t spend time to look into mobile development deeply. Hope that I have a chance this year. DOAG is the right way to gather information and get up to speed with mobile development.

The third and final day i’ve not decided, but it looks like room hopping to get some sessions on SOA, BI and other middleware stuff.

JDeveloper 12c: Features we waited for

JDeveloper 12c has been made available today. As this is a major release it’s worth looking into the new feature list but I noticed some things we have ask for for a couple of month or years and which have been included in this version.

Splash Screen and Icon
Time to get something new to watch at! Fanzy new design with information on what is keeping JDev busy starting up. Well Done!
I like the new icon, RIP old coffee cup.

JDK
Yeah, JDev12c runs with JDK 1.7 under the hood!
The installer does not have the latest 1.7.0_25 on board, but still it comes bundled with 1.7.0_15.
The problems I had with 11.1.1.7.0 running on JDK 1.7 are fixed (at least I had no problems till now).
By the way, if you run the generic installer you need to run it on JDK 1.7.0!

Task-Flow-Templates:
If a task flow is based on a task-flow-template you had to know this (and the functionality) in the 11.1.1.x versions as there was no visual hint for this. JDev12c now shows the task flow template as gray shaded task flow. Good work!

Menu Structure and Toolbars
First thing one notice is that the menu structure has been changed. Sample: menu items to open ‘Database’ view, ‘Application Server’ view and many others are now moved from the ‘View’ menu to the ‘Window’ menu.
The toolbars don’t contain all possible icons available, but now holds only the basic stuff. You can edit the toolbar like your are used to to in e.g. word (the old one!). What I have not found yet (and already missing it) is the ‘Ant’ icon which I used very often.

As it takes time to check out all new stuff I’ll update this post in the next days with new findings.

OTN Forum Update posponed to June 2013

Oracle just announced that the planned update of the OTN forums to a new modern version has been posponed to June 2013.

Quote:

UPDATE – launch delayed for four weeks, into June. 

In a last minute decision we have delayed launch so that we can establish thread level redirects across the site.  I am very happy with this outcome and expect a much smoother transition when we do make the switch.

Good move!  Better wait until all links can be migrated than update and many links are broken.

Bye, Bye Good Old OTN Forums

Starting May 3rd 2013 the good old OTN forum software get it’s desperately needed live-cell therapy. Only a few people know how the new forum software looks like and how it works (I’m none of them).

A couple of things are already known, e.g. some new terminology (spaces instead of forum), more colorful or modern (so better targeted for the facebook generation?), we hopefully get a search which really searches what we are looking for and performance should be better too. You can read for yourself on this OTN thread.

There are some things which are not clear to me, like how all the links posted in threads are handled. From the discussion in the thread above we learn that hopefully all links are migrated. Well, this reminds me when Oracle reorganized its websites. Nothing was reachable any more. There are still link which are broken, forcing us to dig deep in the WWW to get the information back. So let’s hope this will work this time.
However, this adds a lot of work to all the links which are stored in blogs and wikis pointing to interesting information in OTN threads. I’ll lose about 30% of my personal knowledge store and have to update some links here in this blog too.

I don’t want to start a new discussion about the dammed reward system (yes, the points are meant), as they do not alter the system at the moment. Interesting is that there are plans to get real-world rewards at some point in the future (do I get rich?:)).

For sentimental reasons I put a couple of screenshots of the old look and feel in this blog. In a couple of month or years, when dust has settled, we can look back at them and decide if the live-cell therapy has rescued the patient.

JDeveloper 11gR1 Bug in Tuning Node of ViewObject

Today I came across a bug in the tuning node of ViewObjects in JDeveloper 11gR1 (meaning all 11.1.1.x versions). For a prove of concept I played with the tuning options available for ViewObjectes in JDeveloper. The following image shows the the default tuning node of a ViewObject (it doesn’t matter if it’s based on an EntiyObject or not):

Default Tuning Node

Default Tuning Node

As I tested some options I eventually switched to the ‘Only up to row number’ radio button which enables the input field for the number of rows:

Tuning for '...up to row number'

Tuning for ‘…up to row number’

Nothing special there. Now if you delete the number (default is 10)

Delete Number from Field

Delete Number from Field

and ‘tab’ out of the input field, or click on any other field, you get an error dialog telling you that ‘(null) is not a valid fetch size value’.

Error Dialog

Error Dialog

OK, this is correct, but if you hit the OK button or the ‘x’ to close the dialog to put the number back in the dialog stays open, you can’t close it. You don’t get a chance to put the number back into the field. A first I had to kill JDeveloper through the task manager (I did that a couple of times ;)) until I found the following workaround:
            hit the Esc key
you may need to do this multiple times, but the dialog closes eventually and the last number is back in the input field.

This bug is fixed in the current JDeveloper 11gR2 (11.1.2.3.0) version!

Attend ADF EMG Day at OOW 12!

As we all know OOW 2012 is coming up at September 30 – October 4, 2012. Still time to register, book a flight and accommodation 🙂

Well, there are those of us who can’t attend the OOW this year (like myself). For all women and men who can’t make it in person it’s nice to have some first hand information right from the sessions. This is where all the attendees come to play. You can help us with your eyes, ears and fingers. Visit sessions and share information via twitter or write a blog (short or long) to share information.

I’m specially interested in the ADF EMG one day of sessions. Please visit

The Year After the Year of the ADF Developer – the ADF EMG at OOW 2012

and share your thoughts. The ADF EMG day is packed with interesting sessions and are a chance to meet with some community leaders in the JDeveloper and ADF area as well as other people interested in this technology.

The ADF EMG is a place to discuss best practices and methodologies for Oracle JDeveloper ADF enterprise development. This effort is an overall part of getting ADF experts, advocates and programmers to start collaborating. I encourage all you you to help the ADF EMG by attending a session on October 1st, as it shows interest in the very good work the group has done and will do in the future.

And don’t forget to tell us about it!

Changing OTN Notification E-Mail Address (aka Username)

Lately my old web provider told me that he discontinued his service. So I was forced to change my OTN notification e-mail address or username which still used this old provider.
After reading some thread about this, I was not exactly thrilled to do this. Well, there was nothing I could do about it so I decided to ask support how I could minimize the risk of loosing my identity. You find the OTN account help here. It’s hidden in the ‘GETTING HELP ON LOGIN ISSUES’ section as link ‘Submit a help request’.
Now that it seams that the change went well for myself I like to share the procedure given from the ‘Oracle Profile Helpdesk’:

You may update/change the email address associated to your Oracle account by following the steps below:

1) Delete browser cookies, Close and re-open a new browser window.
2) Go to https://myprofile.oracle.com/EndUser/faces/profile/sso/updateUser.jspx, which will take the user to Single Sign On page. Login using your account credentails.
3) Click “Change Username” link on the top right hand corner of the page and a pop up box will appear.
4) Now Type the password of the account for Current Password field, type the new email address (which you want the account to be associated) for New Username field and Similarly type the same email address for Confirm New Username field and Click “Change” button.

That’s easy enough and worked out OK.
