Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: jars being loaded twice Initial Comment: Probably the JARs are loaded twice. Test environment: Eclipse 3.1 (both Linux and Windows), Jetty 5.1.4-all, Jetty Launcher 1.3.0, Tapestry 4.0beta1, Hivemind 1.1beta2 Classpath tab in Run window is okay, doesn't contain double jars. The jars neither appear in system's classpath. After running simple Tapestry application, I get the exception: org.apache.hivemind.ApplicationRuntimeException: Error: Module hivemind is duplicated! Definition in jar:file:/D:/adam/eclipse/test4/app/WEB-INF/lib/hivemind-1.1-beta-2.jar!/META-INF/hivemodule.xml has been ignored in favor of existing definition from jar:file:/D:/adam/eclipse/test4/app/WEB-INF/lib/hivemind-1.1-beta-2.jar!/META-INF/hivemodule.xml. org.apache.hivemind.impl.StrictErrorHandler.error(StrictErrorHandler.java:39) org.apache.hivemind.impl.RegistryInfrastructureConstructor.addModuleDescriptor(RegistryInfrastructureConstructor.java:202) org.apache.hivemind.impl.RegistryBuilder.processModuleDescriptorProvider(RegistryBuilder.java:168) org.apache.hivemind.impl.RegistryBuilder.constructRegistry(RegistryBuilder.java:143) org.apache.tapestry.ApplicationServlet.constructRegistry(ApplicationServlet.java:275) org.apache.tapestry.ApplicationServlet.init(ApplicationServlet.java:216) org.mortbay.jetty.servlet.ServletHolder.initServlet(ServletHolder.java:383) org.mortbay.jetty.servlet.ServletHolder.start(ServletHolder.java:243) org.mortbay.jetty.servlet.ServletHandler.initializeServlets(ServletHandler.java:445) org.mortbay.jetty.servlet.WebApplicationHandler.initializeServlets(WebApplicationHandler.java:323) org.mortbay.jetty.servlet.WebApplicationContext.doStart(WebApplicationContext.java:511) org.mortbay.util.Container.start(Container.java:72) org.mortbay.http.HttpServer.doStart(HttpServer.java:753) org.mortbay.util.Container.start(Container.java:72) com.iw.plugins.jettyrunner.PluginRunner.launch(PluginRunner.java:282) com.iw.plugins.jettyrunner.PluginRunner.launch(PluginRunner.java:104) com.iw.plugins.jettyrunner.PluginRunner.main(PluginRunner.java:75) When removing hivemind jar from Project Build path, I get class not found at runtime. Running on standalone Jetty works perfectly, so does Tomcat, therefore my webapp is okay. ---------------------------------------------------------------------- >Comment By: Geoffrey Longman (glongman) Date: 2005-07-07 11:33 Message: Logged In: YES user_id=387057 ah yes. All jars in the project build path are added. The trouble comes when the jars in the build path are located in WEB-INF/lib in the project. By the nature of the Servlet spec all the jars in WEB-INF/lib are loaded - effectively causing the dup problem. I though there was a workaround in JL from a long time ago that took care of this. looking.... found it - I didn't fix the problem way back when... http://sourceforge.net/tracker/index.php?func=detail&aid=975287&group_id=50321&atid=459328 ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2005-07-07 11:24 Message: Logged In: NO OK, I've found a reason. I had the jars in WEB-INF/lib. When running with Jetty Launcher, this directory was in classpath (as it was in Eclipse Build Path). But it was also standard j2ee libraries directory, therefore it was also parsed. The fix should check whether WEB-INF/lib was already in classpath or not. ---------------------------------------------------------------------- Comment By: Eelco Hillenius (eelco12) Date: 2005-07-07 09:31 Message: Logged In: YES user_id=820266 I think that is the case for projects that have the actual jars in WEB-INF/lib. I use maven, so I never have that, and I never removed this functionality because my guess is that Geoff had a reason (Tapestry related) to load the jars when they can be found in WEB-INF/lib. So, Geoff, could you inform us about that reason? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=682377&aid=1234167&group_id=118870 ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
