do you put in the line Tapestry-Module-Classes: net.godcode.tapex.testlib.LibModule manually or do you use a maven plugin to generate it?
if you do it manually ensure that you have exactly 2 linefeeds at the end of the MANIFEST.MF file or it won't work.... a really annoying Java bug... just a guess :) g, kris Chris Lewis <[EMAIL PROTECTED]> 20.09.2007 14:51 Bitte antworten an "Tapestry users" <[email protected]> An Tapestry users <[email protected]> Kopie Thema Re: [T5] Can't make custom library work Ick - that would be annoying if it was because you aren't using Jetty... Answers to your questions: 1. No, my lib module has only that method. 2. Yes. When packaged it lives right beside the component class. 3. No. My template is simply this: "<div>${message}</div>" 4. Yes (see below). 5. No, not significantly (see below). Here is are all files in my component jar: META-INF/MANIFEST.MF META-INF/maven/net.godcode.tapex.testlib/tapestry5-testlib/pom.xml META-INF/maven/net.godcode.tapex.testlib/tapestry5-testlib/pom.properties net/godcode/tapex/testlib/components/TestComp.class net/godcode/tapex/testlib/components/TestComp.html net/godcode/tapex/testlib/LibModule.class Ignore the items under META-INF/maven/ - maven sticks these in generated artifacts. Here is my MANIFEST.MF: Manifest-Version: 1.0 Archiver-Version: Plexus Archiver Created-By: Apache Maven Built-By: chrislewis Build-Jdk: 1.5.0_07 Tapestry-Module-Classes: net.godcode.tapex.testlib.LibModule Again, maven sticks much of that in the manifest. The only line I tell maven to insert is "Tapestry-Module-Classes". This of course points to my lib module class. Here are my exact source files, in case they are of help to you. See my earlier post on how I reference my components and the inconsistency, depending on if you use instrumentation or not. TestComp.html (component template): <div>${message}</div> TestComp.java (component class): package net.godcode.tapex.testlib.components; import org.apache.tapestry.MarkupWriter; import org.apache.tapestry.annotations.BeginRender; /** * TestComp * * @author Chris Lewis Sep 19, 2007 * @version $Id$ */ public class TestComp { public String getMessage() { return "Test message"; } @BeginRender void beginRender(MarkupWriter writer) { writer.write("??"); } } Note that the beginRender was just a test. The result is output appearing before my template body, as expected. LibModule.java (library module): package net.godcode.tapex.testlib; import org.apache.tapestry.ioc.Configuration; import org.apache.tapestry.services.LibraryMapping; /** * LibModule * * @author Chris Lewis Sep 19, 2007 * @version $Id$ */ public class LibModule { public static void contributeComponentClassResolver(Configuration<LibraryMapping> configuration) { configuration.add(new LibraryMapping("testlib", "net.godcode.tapex.testlib")); } } And thats it. I can refer to my components using "<t:testlib.TestComp/>" or with instrumentation "<div t:type="testlib/TestComp"/>" - note the difference. Deviations will cause an error, and this should be considered a bug. Let me know how you progress, and share your exact source if you'd like. sincerely, chris Kolesnikov, Alexander GNI wrote: > I wonder if my problem is a classloader issue...
