After saving your java class and opening a XPage you should see the message on the server console (perhaps you have to do a clean first).<\/p>\n This means that the Factory is now accessible and is ready to use. The class will only be instantiated once during runtime.<\/p>\n 5. To use your Factory, you have to do a lookup first, before you can use it. This can be done using the com.ibm.xsp.factory.FactoryLookup<\/em> class which can be accessed via the current application<\/a> (Please read the notice in the ExtAPI documentation!).<\/p>\n Here is a SSJS code snippet:<\/p>\n The main difference between a managed bean and this approach is, that the class is instantiated as soon the JSF application starts running, not if you access the bean in your code for the first time. The factory class can do what you want, f.e. run a thread or whatever. The result of the operations can be accessed via the\u00a0 factory lookup.<\/p>\n P.S.\u00a0Keep in mind that this article has been posted in the „Quick-n-Dirty<\/strong>“ category.<\/p>\n","protected":false},"excerpt":{"rendered":" Here is a easy way to use your own factory classes in XPages: 1.
