... wird sicher nicht mein Hauptprojekt, aber im November hab ich das Wissen und den Schein.
Nett.

--- Zitat ---. IBM offers Lotus customers a long-term roadmap for those Notes applications -- both stand-alone and/or integrated into other infrastructure (Portals, WebSphere applications, IBM Workplace client technology, etc.)
--- Ende Zitat ---
Redmond does not sleep and is allways ready to attack. ;D
In diesem Sinne habe ich nun begonnen ein paar dieser Fragen zu beantworten. Ich kann das direkt oben in die Postings reinschreiben. Ihr müsst das unten dranhängen und ich tue das dann nach oben.
Wenn also sich jemand drauf einlassen will. Nur nicht schüchtern.
Bin jetzt auf Seite 100 vom ersten Redbook. Ziemlich langweilig geschrieben muss ich sagen. Das geht wirklich besser.
Trick: Ich lese die Teile über WAS Enterprise Edition inzwischen nicht mehr. Das ist eh nicht Bestandteil des Tests und ich gehe von Folgenden aus:
a) meine Kunden haben kein Geld dafür.
b) diese Angeberfeatures funktionieren sowieso nicht.
In diesem Sinne.
Mein Ziel ist es bis Ende dieses Monats alle Fragen beantwortet zu haben (ich mach noch einen Haufen anderen Kram).
Gruß Axel

... das ist nun für mich ein low priority task.
5 x 8 h Wochen kommerzielle Arbeit (wie so oft theoretisch, praktisch mehr) und sehr starkes Interesse an der Vertiefung von iBatis/Hibernate+Spring und zahlreicher Dinge drumrum machen es faktisch unmöglich oder ich erschlage am Ende dieses Monats einen meiner Kunden.
Im http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=forum&f=61 gibt es zur Zeit ein sehr starkes Interesse an 340. Vermutlich werde ich es anglifizieren und irgendwann bald asia united zum Frass vorwerfen. Vielleicht kommen ja ein paar hilfreiche Beiträge.
Gruß Axel
