All Just remember that whatever you use, you will need to stay the right side of the IBM licensing policy.

RE: [U2] UniObjects in Web App
Kathy, We wrote our own middleware called U2WebLink that uses UniObjects for Java. The logging capability of UniObjects is not very good. We added an open source package called Apache log4j to our middleware to handle logging for UOJ. UOJ is not thread safe and the connection software you write must take that into account. We would not recommend to anyone that you try to write your own connection manager. We been there and done that. However, that is what you have to do in order to guarantee that you don't step on your connections. Regards, Doug _ Express your personality in color!

RE: [U2] UniObjects in Web App
We are using classic ASP and UniObjects (not .NET). The forum posting I'm referring to is from Jan. 2007 and says the current version doesn't do too well with .Net - it is not thread safe, which limits SOME of the things you can do with it (ie don't try using it through a web server). Here's the link: http://212.241.202.162/cms/cmsforum.wsp?action=topicforum=1topic=26 http://212.241.202.162/cms/cmsforum.wsp?action=topicforum=1topic=26 I know forum posts are not always accurate and the IBM website indicates that both UniObjects and UniObjects.net are fine for web apps. FWIW, the error we're getting in IIS is A trappable error occurred in an external object. The script cannot continue running. What's strange is that even when we see that error, the app sometimes continues working and other times we have to restart IIS. I'm trying to figure out if I need to re-write this app using .Net or take some other approach to solve the issues we're having. I'm also wondering if isolating this app into it's own application pool in IIS would make a difference (I understand that may be a question for an IIS forum). Thanks for your response.

RE: [U2] UniObjects in Web App
Sorry i have only ever played with uniobjects with ASP and never used it in anger - i use uniobjects.net - it is correct you should not use the old uniobjects with .net but use the uniobjects.net api as this is fully managed code.

RE: [U2] UniObjects in Web App
For anyone not familiar with this area: You can make use UO.NET with ASP, though you need to call the .NET client side interface from a COM wrapper. That is: ASPWrapperUO.NETU2 Similarly, you can use the UniObjects COM component from .NET: .NET ClientWrapperUOU2 Personally I'm more of a purist and prefer either COM or .NET all the way through. In real life we're frequently finding our .NET code called from COM applications like Microsoft Office, or making use of existing COM DLLs from within our .NET code. There are good reasons to use one or the other, and real pains sometimes in mixing the two. But what's important here is that it looks like Kathy believes that changing the communications components may require completely changing the web GUI. That is not correct. Make the decision about switching from ASP to ASP.NET on its own merits, and switching UO to UO.NET or other components on their own merits as well. .NET isn't just another technology for its own sake, it fixes a Lot of the problems of prior technologies. The more you use .NET all the way through the better. But don't feel like you're forced to do a mass conversion or nothing at all. Feel free to contact me off-list if that needs clarification.
