Problem with StandardDeploymentStrategy in Seam 2.1.0.BETA1
I'm getting the following error with Seam 2.1.0.BETA1 and Tomcat 6, whereas it was working with a Seam 2.1.0-SNAPSHOT from about a week ago:
java.lang.IllegalStateException: Cannot load WEB-INF/classes/schemaorg_apache_xmlbeans/system/s91E100311FD7B2754860C7FE37BCF739/TypeSystemHolder.class from WebappClassLoader delegate: false repositories: /WEB-INF/classes/ ----------> Parent Classloader: org.apache.catalina.loader.StandardClassLoader@b5dac4 (using getResourceAsStream() returned null) at org.jboss.seam.deployment.AbstractDeploymentHandler.getClassFile(AbstractDeploymentHandler.java:41) at org.jboss.seam.deployment.ComponentDeploymentHandler.handle(ComponentDeploymentHandler.java:57) at org.jboss.seam.deployment.DeploymentStrategy.handle(DeploymentStrategy.java:177) at org.jboss.seam.deployment.AbstractScanner.handleItem(AbstractScanner.java:30) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:141) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:137) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:137) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:137) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:137) at org.jboss.seam.deployment.URLScanner.handleDirectory(URLScanner.java:137) at org.jboss.seam.deployment.URLScanner.scanDirectories(URLScanner.java:40) at org.jboss.seam.deployment.StandardDeploymentStrategy.scan(StandardDeploymentStrategy.java:107) at org.jboss.seam.init.Initialization.create(Initialization.java:113) at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:34) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3843) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4350) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:516) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:578) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)
As you can see, the ClassLoader is incorrectly trying to load a class that starts with WEB-INF/classes/schemaorg_apache_xmlbeans instead of just schemaorg_apache_xmlbeans.
I have traced the issue to the following line in Initialization:
public Initialization create()
{
standardDeploymentStrategy = new StandardDeploymentStrategy(Thread.currentThread().getContextClassLoader());
// THE FOLLOWING LINE HAS BEEN ADDED IN SEAM-2.1.0.BETA1
standardDeploymentStrategy.getFiles().add(warRootDirectory);
standardDeploymentStrategy.scan();
addNamespaces();
initComponentsFromXmlDocument("/WEB-INF/components.xml");
initComponentsFromXmlDocument("/WEB-INF/events.xml"); //deprecated
initComponentsFromXmlDocuments();
initPropertiesFromServletContext();
initPropertiesFromResource();
initJndiProperties();
return this;
}
As you can see, I have specified a path for the docBase in server.xml instead of a war file.
Any suggestions? Thanks in advance.
