Yeah, I am doing this by hand and I know the trick with line feeds. This is not a problem in my case as logging shows that Tapestry does load the library module and does run the contributeComponentClassResolver() thing.
It is really strange that it works for everyone except of me :)) I am beginning to think that my IBM JVM here may somehow influence the result. Yes, the problem is definitely not in Tomcat - I just didn't realize that both FCKEditor and DatePicker work fine in the same test app. Will try everything from scratch on a different computer tomorrow... :D -----Original Message----- From: Kristian Marinkovic [mailto:[EMAIL PROTECTED] Sent: 20 September 2007 14:10 To: Tapestry users Subject: Re: [T5] Can't make custom library work 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>${message}</div>" 4. Yes (see below). 5. No, not significantly (see below). Here is are all files in my component jar: META-INF/MANIFEST.MF META-INF/maven/net.godcode.tapex.testlib/tapestry5-testlib/pom.xml META-INF/maven/net.godcode.tapex.testlib/tapestry5-testlib/pom.propertie s net/godcode/tapex/testlib/components/TestComp.class net/godcode/tapex/testlib/components/TestComp.html net/godcode/tapex/testlib/LibModule.class Ignore the items under META-INF/maven/ - maven sticks these in generated artifacts. Here is my MANIFEST.MF: Manifest-Version: 1.0 Archiver-Version: Plexus Archiver Created-By: Apache Maven Built-By: chrislewis Build-Jdk: 1.5.0_07 Tapestry-Module-Classes: net.godcode.tapex.testlib.LibModule Again, maven sticks much of that in the manifest. The only line I tell maven to insert is "Tapestry-Module-Classes". This of course points to my lib module class. Here are my exact source files, in case they are of help to you. See my earlier post on how I reference my components and the inconsistency, depending on if you use instrumentation or not. TestComp.html (component template): <div>${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...
