ApplicationDidFinishLaunchingNotification Problem
There is a handy notification in WOApplication called ApplicationDidFinishLaunchingNotification for which you can register an observer. In fact, this is what Wonder uses for ERXApplication's didFinishLaunching(). However, I've noticed that when when building for deployment as a servlet (using Leopard Server & Tomcat), no observers for ApplicationDidFinishLaunchingNotification get called! If I deploy as a .woa it works fine, but as a servlet it does not. I've reduced it to a very simple test case and will file a bug with Apple, but I just wanted to find out if anyone else has seen this problem? Is there a recommended alternative for performing one time application startup batch operations other than in the constructor or using ApplicationDidFinishLaunchingNotification? I guess there is always the request-response loop... Thanks, Aleksey ___ Do not post admin requests to the list. They will be ignored.

Re: WO 5.4 Linux Deployment
It does seem benign. I'm wondering if anyone knows how (javax.naming.NameNotFoundException: Name jdbc is not bound in this Context) might be suppressed. Thanks, Aleksey This does not cause any problems ... It's an obnoxious error that isn't really an error. It's been a couple months since I tracked down what exactly was going on, but I _believe_ it's trying to lookup the jdbc datasource in your tomcat server config, and if it's not there, it displays this warning. You can safely ignore it. ms On Apr 2, 2008, at 5:14 PM, Jeff Smith wrote: FWIW, I'm getting the "java name not found in context" as well and I haven't figure out a way around getting the messages either including specifying my data source in the web.xml.

Re: WO 5.4 Linux Deployment
Thanks Jeff! I tried this and found that the latest Eclipse/WOLips tools are very complete in packaging up woapps for servlet deployment. However, there were a couple of caveats worth mentioning: 1. Starting with a WOnder Application template there is no need (and no option!) to create a project with servlet support. All that is needed after the project is created is to check Servlet Deployment and check Autogenerate web.xml in WOLips Build within the project properties. This will create the proper WAR file as a fully self- contained servlet single directory deployment (SSDD) with all of the necessary WO frameworks. It's very slick. 2. Project dependencies (such as other frameworks) however will not be included in the SSDD. They must be included as framework dependencies as well. See http://wiki.objectstyle.org/confluence/display/WOL/Add+a+Framework+Dependency . 3. The generated web.xml file in WEB-INF has a parameter named WOAppMode which is set to "Development". I found that with this setting, Tomcat and the WebObjects Resource Manager would not serve up any static WebServerResources correctly. I kept getting links like "/ MyApp/WebObjects/MyApp.woa/_wr_/wodata=/Library/stuff". I don't know if I had a particular property value set incorrectly. But I did find that if I changed the WOAppMode value to "Deployment", the problem went away since the static resources get served up directly by the web server. This of course requires a split install (Tomcat + Apache). Because I'm using Ajax, I had to remember to include Ajax.framework/ WebServerResources in the split install since there are critical javascript files that are required. 4. For the static resources to be served correctly via port 80 of the Apache web server (as opposed to Tomcat's port 8080), I had to install the Tomcat-Apache plugin, mod_jk. I am deploying on Linux, but developing on a Mac, and so I wanted to make sure this also works under Leopard. There are useful instructions for installing mod_jk on Leopard client at http://blog.lo-fi.net/2007/10/leopard-for-web-developer-installing.html (the downloadable binary for mod_jk for Leopard doesn't run correctly). 5. In the Tomcat log file (catalina.out), I keep getting an exception (below) related to JDBC but everything runs fine regardless (I'm using MySQL). Tomcat seems to have it's own data source mechanism for supplying database information. Being a Tomcat newbie, I'm not sure if there is an easy way to suppress these exceptions, or if it's better to just configure and use the servlet container data source. I know there is some pertinent information at http://wiki.objectstyle.org/confluence/display/WO/Web+Applications-Deployment-Tomcat+Deployment , but I'm interested in getting input on best practices related to WO deployment and data sources in a servlet container. Please let me know, especially if you have experience with business-critical deployments.

Nothing special being used here, mainly the standard dev tools/WO install from Apple (5.4) and then Eclipse +WOLips (latest stable) to build the project/WAR files. As a matter of fact, I've found that just creating the projects with servlet support and then checking the WOLips boxes for Servlet deployment and automatically generating the WAR files (in the preferences) was all I needed to do to get the proper WAR file generated.
