RE: Use System ClassLoader with Tapestry5
Hi, I'm a dwr user not a tapestry user... I usually only listen on this list. To do this you would need to implement a tapestry creator (http://getahead.org/dwr/server/dwrxml/creators). See the org.directwebremoting.spring.SpringCreator for inspiration. You would probably want to hook into tapestry's page pooling / page initialization instead of calling PageClass.newInstance()... can't help you there sorry. Please consider submitting your solution to the dwr users list for inclusion in the project http://getahead.org/dwr/support. Cheers, Lance. -Original Message- From: Howard Lewis Ship [mailto:[EMAIL PROTECTED] Sent: 14 January 2008 16:03 To: Tapestry users Subject: Re: Use System ClassLoader with Tapestry5 Tricky. The class loader Tapestry uses does two different things: - Transforms the class (for injections, parameters, and lots of other stuff) - Handles reloading of classes when they change When a .class file on the disk changes, Tapestry will actually discard the class loader and create a new one. I suspect you are going to have to go into the internals of DWR and Tapestry in order to get this to work properly. You can inject the @ComponentLayer ClassLoader and obtain the current ClassLoader from it.

Use System ClassLoader with Tapestry5
