You know, after reading a bit on Martin Fowler's site and a few others, I am completely warm and fuzzy about an event architecture. It decouples my code even more. I was actually feeling opposite of how I should have been. I also have found EventBus for swing and non-swing and looks to be pretty...

Hi all, I am building a JSR-296 swing app ontop of a spring backend using remote services. The new BSAF has a pretty nice @Action/Task architecture. My basic question is; I need, pretty much everywhere, to register as a listener for Task events but my objects are disparate. Meaning I have no...

thanks sedj, All tests you said I have tried and they work fine. I am 100% sure that nothing on my side changed. I honestly do think someone is covering up something here but I can't prove it. Thats why I am trying to maybe get even a small clue on what it could possibly be so maybe I can...

Hi all, I have a huge issue here at my place of employment and I am at a loss. This application has been running for at minimum a year and last wed I started having problems. This application simply reads in a jpeg stream and writes it to an oracle table using hibernate. The problem I see is...

Hi all, I can't seem to find a natural way to use JMS to solve my following problem. If anyone can point me towards a website, tutorial or anything in the correct direction I would appreciate it. Here is the situation 3rd party sends xml files to me for events per an entity First I bind the...

The problem that seems to un-common to me is that my log is for my application. Not for an oracle instance. Actually I the real reason is because a package is used to write out a file that needs to be downloaded and instead of centralizing that file I am forced to keep multiple copies. This...

Hi karluk, thanks for the response. Hmm, so if you just log say errors from the db, you have to search through (n) machines and files to find all the logs? Brian Spend like you don't need the money, love like you've never been hurt and dance like nobody's watching!

Sorry, I should say that I am being told that whatever node is active at that moment is where the file will be written to. i.e. If i am on server1 that is where my log is, if on server2 it would be there and on server3 it would be there. So I have a log file called queue.log and there are 3...

Hi all, I am wondering if an oracle rac can write to one remote file server machine. I am being told that this is not possible but it seems like a elementary task. Thanks for your help. Brian Spend like you don't need the money, love like you've never been hurt and dance like nobody's watching!

Guys, I don't think NOT finding a record should be considered an exception. Do you? Andrew was simply asking if he should throw an exception or return null if a record is not found. Trojan stated it correctly IMHO. Brian Spend like you don't need the money, love like you've never been hurt...

Thanks grooke, I did kind of think that was the case but wasn't really sure. Brian Spend like you don't need the money, love like you've never been hurt and dance like nobody's watching!

You know what. I am going to use a web services and stop trying to re-invent the wheel. Brian Spend like you don't need the money, love like you've never been hurt and dance like nobody's watching!

Hi all, I think I know the better answer but I just wanted some input. I only pass DTO's over the wire. (In the body of a Message object) I at the very least have 2 implementations of my objects. A DTO implementation and a DomainObject implementation. interface IMyObject MyObjectDTO...

Hi, I have a similar situation in which I introduce a NullObject that can be understood no matter where it is returned from. For example you say you have a Thingy class. First make an interface IThingy to use. Then make your implementation classes; NullThingy and Thingy. Then make something...

Thank you, Not familiar with JMX but thank you for pointing me in that direction. I am sure to learn it soon and I really hate having to refactor from a TOTALLY bad design because I just don't have the knowledge. Brian Spend like you don't need the money, love like you've never been hurt...

Thanks sedj, well I have to write a transformation layer between my company and a third-party we contracted. The means of communication is xml to them and we use dto's from the client. The main responsibility for me is to transform our dto's into the proper xml format, send the xml to the...

Hi all, Not sure if this is specific to J2EE (sorry if it is not) Would it be good form to use filter servlets to ALWAYS transform any request in my web app to a DTO's instead of doing the transformation in a regular call in the web app? Thanks in advance Brian Spend like you don't need the...

Thanx Spend like you don't need the money, love like you've never been hurt and dance like nobody's watching!

Hi all, I was wondering if anyone has any experience with a SOLID java front end that can connect to any database. I DO NOT want to install Oracle ANYTHING on my new machine. I would like a tool that can use jdbc and connect to MySql, Oracle Sql Server etc... so I can use the same app for all...

Actually I just found an elegant way to do this with the Interpreter pattern [GoF]. Actually it is the QueryObject pattern in Martin Fowler's Patterns of Enterprise Application Architecture. If anyone is interested please look to either of these books although the Fowler one is exaclty what I...
