site_archiver(a)lists.apple.com Delivered-To: Webobjects-dev(a)lists.apple.com Thread-index: AcUH70sPkRsRIiDfTie8xJkBK5UX8A== Thread-topic: Status of Windows support Can someone tell me about the status of Windows support for WO development generally, please? For example, are the development tools on a par with the OSX tools; are there issues in development or deployment created by the cross-platform work, etc? Any feedback at all and outrageous opinions generally :-) would be of interest. Regards Lachlan Scott _______________________________________________ Do not post admin requests to the list.

Re: About Database Vender Independent for WebObjects.

site_archiver(a)lists.apple.com Delivered-To: webobjects-dev(a)lists.apple.com For example... public JGeometry getGeometry() { String geometryString = this.geometryAsString(); // code to deserialize the object JGeometry jg = theMagicDeserializer(geometryString); return jg; } public void setGeometry(JGeometry jg) { // code to serialize the object String geometryString = theMagicSerializer(jg); this.setGeometryAsString(geometryString); } Hope that helps a bit. .steve On Jan 30, 2005, at 7:09 PM, Marina Zheng wrote: We use Oracle existing plungin's, "ojdbc14.jar" and "sdoapi.jar". WO may includ ojdbc14.jar but I don't think it has sdoapi.jar by default. So you mean if I include sdoapi.jar(containing class "JGeometry") into EOF, EOF will then be able to use JGeometry type to map to Geometry data type from db? I doubt it that WO will know how to read it first to Oracle.sql.Struct and then load it to JGeometry type though. Any way, what I really want to know is if you can actuall modify Enterprise Object after it's generated by EOF. If not, it's then impossible to use EOF for Geometry type. You must then be able to manually create an EO from scratch and enbed some SQL scripts to do the job. Maybe I sound confusing here with this too...never mind then. Thanks a lot, Dov and own. --marina This email sent to steve(a)union.arizona.edu _______________________________________________ Do not post admin requests to the list. They will be ignored. Webobjects-dev mailing list (Webobjects-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/webobjects-dev/site_archiver%40lists… Looks to me like all you want to do is have the JGeometry object serialized in some form in the database. You can just add new getter and setter methods that serialize the object for you before passing it off to a String which gets saved in the db. In EOModeler create the attribute geometryAsString, map it to a field in the db, and set the type to String. Then generate java files for your entity. You should then have a MySpecialEO.java (or whatever) with getter and setter methods for your attribute. Something like geometryAsString() and setGeometryAsString(). These will access the String representation of the JGeometry object. You need to add another set of getters and setters that take a JGeometry type. So add the following to the class. The key to making this work correctly is not simply overriding getGeometryAsString to return a JGeometry, WO still needs to access that method as a String. Also note that the geometry() attribute isn't in the EOModel, but when working with the EO in your code you can pretend that it is. The only part that's left up to you to figure out is how to serialize the JGeometry object as a string, which should be easy to do. __________________________________________________ Do You Yahoo!?

I still don't understand why this would not happen automatically. I use cookies all the time for this and don't use any such code. What am I missing, what is different about your situation? It would be quite interesting to see the stack traces from a thread dump of an that has an immortal session as the result of this code. I felt this code was the root of the issue since the problem didn't exist prior to adding the code. And, after removing it, the problem disappeared. What exactly is the purpose of that piece of code? It seems like createSession would only be called if it has not already been determined that the session could not be restored. Do you have a stack trace? Why do you think this code is the cause of your problems? At 12:41 PM 29/01/2005 -0800, George Domurot wrote: Chuck/Helge/Tim: Thank you for the ideas and pointers. I was able to pinpoint the issue down to a bit of code I added to restore returning visitor's sessions. I picked it up from someone's earlier posting/notes. Here's the code from the Application class: if (aContext!=null){ String sessionID = aRequest.cookieValueForKey(WORequest.SessionIDKey); String instance = aRequest.cookieValueForKey(WORequest.InstanceKey); if(!XOEO.Empty(sessionID)) aSession = restoreSessionWithID(sessionID, aContext); } if(aSession == null) return super.createSessionForRequest(aRequest); Any ideas why this would cause the problem? Also, looking at the code a bit more, the line about the instance number doesn't seem relevant to the method. We have an app that doesn't want to release inactive sessions (usually just 1). This becomes a problem during scheduled graceful cycling. There are other apps running under the same deployment scenario for more than a year, all smooth. _______________________________________________ Do not post admin requests to the list.

Best regards, Janice For some reason, the run log messages are not appearing when I run a particular application, but for other applications all messages are viewable. It just shows that ["Session started at 2005-01-31 12:52:21 - 0500"], and nothing else, whereas other applications seem to have the proper run log paths, messages, etc. Is there something I can enable somewhere?

Experienced! :-) Sadly, I have to give up really working towards WO for now. I've been researching on it because I was thinking about it as my project topic. However, I failed to find someone who's developed in WO to be my advisor. So I'll have to now start searching for other topics. I'd love to get my hands dirty with WO when I got a chance, but probably not this semester. I have 3 classes now with my project, I also would like to audit a course on the design and development of WebLogic by a senior BEA System Engineer, and I'm working part time. So I don't think for now. Maybe later. Thank you guys. I'll be staying here just "watching" and hopefully some day I'll really try WO out and back to many questions for you all. :-D I like it here because it's nice and responsive.

Cloudscape/Derby and WebObjects

When the source is released, one could make a framework and incorporate Derby as an embedded database in a WebObjects application. This would permit debugging with a java debugger on both sides of the EnterpriseObjects frameworks. Also, one could distribute applications as one package without worrying about providing for database connectivity. If one deployed as a war, you could plunk the app into JBoss or even Tomcat with minimal deployment descriptors. This email sent to site_archiver(a)lists.apple.com

I can't find the version for the latest version of WO, though. It's NOT a standard type....wait, it is most likely a standard implementation of "OpenGIS" specification. But it's then from database point only. You then need a standard java API(Like JGeometry) to access it too and I'm not sure if OpenGIS has specified these APIs. However, Struct is for sure proprietary to oracle ONLY, and JGeometry is probably so. In whatever case, even if both Geometry and the java APIs for it is standard of OpenGIS, I don't really think WO has implemented anything about OpenGIS so WO won't be able to handle it for you then. --marina > Hi Owen, > > Thank you very much for the reply. > > I don't know exactly how to use EOF and code for it, but I think I > know the idea of it.
