I wonder if my problem is a classloader issue... I guess most people here are running Jetty why I am using Tomcat...
Which server do you use, Chris? -----Original Message----- From: Kolesnikov, Alexander GNI Sent: 20 September 2007 11:17 To: Tapestry users Subject: RE: [T5] Can't make custom library work Hi Chris, I know all this about how to reference the component. And I don't use Maven. I check the contents of the packaged JAR to see if everything as expected. And still, I can't make my trivial component available to the application. Could you please tell me a few things about your library: 1. Does your library module contain anything but contributeComponentClassResolver() method? 2. Does your component(s) have a template, and if yes, is it packaged next to the component class, in the same Java package? 3. Do you use <html xmlns:t="..."> </html> in your component's template? 4. Do you package components and module in the same way as I do: >> META-INF/MANIFEST.MF >> com/test/TestModule.class >> com/test/components/TestComp.class >> com/test/components/TestComp.html 5. Is your MANIFEST.MF significantly different from mine: >> Manifest-Version: 1.0 >> Tapestry-Module-Classes: com.test.TestModule Thanks, Alex -----Original Message----- From: Chris Lewis [mailto:[EMAIL PROTECTED] Sent: 19 September 2007 18:29 To: Tapestry users Subject: Re: [T5] Can't make custom library work Ok I've made some progress. First of all, my component not loading issue was a problem with eclipse/maven plugin. As I said I created a different project for my test component lib, also using maven, and used mvn install to install the artifact to my local repo. I manually added this artifact as a dependency to my Tapestry app's pom.xml, and then things got a bit odd. The maven 2 plugin creates an eclipse library that dynamically includes all artifact jars of each artifact listed as a dependency in the pom. However, with my test lib it didn't to this. Instead it showed a bland folder icon with the same name as my test lib project. I verified this was caused by my pom entry by removing the dep from the pom and cleaning the project. So to confirm this test I created a "normal" user library (called "Mine") and manually added the test lib artifact to it. Now I am able to use my component in my tap app! If anyone has any suggestions for configuring eclipse/m2 plugin to behave, that'd be much appreciated! Now how to reference the component. I've noticed some slight inconsistencies in using components (or passing component params) in templates. For my component, if I want to use tap's invisible instrumentation, I have to do this: <div t:type="testlib/TestComp"/> Note that this WILL NOT work: <div t:type="testlib.TestComp"/> However, the inverse is true using tap-namespaced tags: <t:testlib.TestComp/> Works, while this DOES NOT: <t:testlib/TestComp/> That makes sense because "<t:testlib/TestComp/>" is invalid XML, but the fact that "<div t:type="testlib.TestComp"/>" causes an error is inconsistent, and I find it a bit annoying. I hope this helps - let me know how you fare. sincerely, chris Kolesnikov, Alexander GNI wrote: > Hi Chris, > > The only idea I have so far is that the problem is in HTML template > that goes into the same package as the page class.
