[ http://issues.apache.org/jira/browse/AXIS-2533?page=comments#action_12434498 ] Curtis Porter commented on AXIS-2533: -------------------------------------
Copying axis.jar into WEB-INF/lib is a workaround, but it bloats the size of the webapp's .war file. > NullPointerException when redeploy axis context using Embedded Tomcat, first > time deploy is working fine (other context are fine) > --------------------------------------------------------------------------------------------------------------------------------- > > Key: AXIS-2533 > URL: http://issues.apache.org/jira/browse/AXIS-2533 > Project: Apache Axis > Issue Type: Bug > Components: Deployment / Registries > Affects Versions: 1.4 > Environment: Tomcat 5.0.28 as Embedded host, Axis 1.4, JDK 1.4.2_11, > Windows XP Pro SP 2 > Reporter: Patrick > Priority: Blocker > > We are using Tomcat 5.0.28 as Embedded host, then deploying /axis context to > handle web services. > When the application starts up initially, deploying /axis context works fine. > But we want to be able to make changes to the web services deployed under > axis, so we need to be able to undeploy the /axis context in the embedded > Tomcat, then redeploy the /axis context again, which at this point the > exception occurs (stack trace below). I think - correct me if I'm wrong - > it's something to do between axis and commons-discovery caching the class > loader (even though it is a new context - hence using new class loader)? I > have looked at the issue database, while there are something along the lines > of redeploy problem, I found none with similar exception (stack trace), hence > I'm posting this. > StandardContext[/axis]Servlet /axis threw load() exception > javax.servlet.ServletException: Servlet.init() for servlet AdminServlet threw > exception > at > org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1071) > at > org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:862) > at > org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4013) > at > org.apache.catalina.core.StandardContext.start(StandardContext.java:4357) > at > org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:823) > at > org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:807) > at > org.apache.catalina.core.StandardHost.addChild(StandardHost.java:595) > ... > ----- Root Cause ----- > java.lang.NullPointerException > at > org.apache.catalina.loader.WebappClassLoader.findResources(WebappClassLoader.java:956) > at java.lang.ClassLoader.getResources(ClassLoader.java:851) > at > org.apache.commons.discovery.jdk.JDK12Hooks.getResources(JDK12Hooks.java:150) > at > org.apache.commons.discovery.resource.DiscoverResources$1.getNextResources(DiscoverResources.java:153) > at > org.apache.commons.discovery.resource.DiscoverResources$1.getNextResource(DiscoverResources.java:129) > at > org.apache.commons.discovery.resource.DiscoverResources$1.hasNext(DiscoverResources.java:116) > at > org.apache.commons.discovery.resource.names.DiscoverNamesInFile$1.getNextClassNames(DiscoverNamesInFile.java:186) > at > org.apache.commons.discovery.resource.names.DiscoverNamesInFile$1.getNextClassName(DiscoverNamesInFile.java:170) > at > org.apache.commons.discovery.resource.names.DiscoverNamesInFile$1.hasNext(DiscoverNamesInFile.java:157) > at > org.apache.commons.discovery.resource.names.NameDiscoverers$1.getNextIterator(NameDiscoverers.java:143) > at > org.apache.commons.discovery.resource.names.NameDiscoverers$1.hasNext(NameDiscoverers.java:126) > at > org.apache.commons.discovery.resource.classes.ResourceClassDiscoverImpl$1.getNextResource(ResourceClassDiscoverImpl.java:159) > at > org.apache.commons.discovery.resource.classes.ResourceClassDiscoverImpl$1.hasNext(ResourceClassDiscoverImpl.java:147) > at > org.apache.axis.configuration.EngineConfigurationFactoryFinder$1.run(EngineConfigurationFactoryFinder.java:120) > at java.security.AccessController.doPrivileged(Native Method) > at > org.apache.axis.configuration.EngineConfigurationFactoryFinder.newFactory(EngineConfigurationFactoryFinder.java:113) > at > org.apache.axis.transport.http.AxisServletBase.getEngineEnvironment(AxisServletBase.java:273) > at > org.apache.axis.transport.http.AxisServletBase.getEngine(AxisServletBase.java:172) > at > org.apache.axis.transport.http.AxisServletBase.getOption(AxisServletBase.java:396) > at > org.apache.axis.transport.http.AxisServletBase.init(AxisServletBase.java:112) > at javax.servlet.GenericServlet.init(GenericServlet.java:261) > at > org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1029) > at > org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:862) > at > org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4013) > at > org.apache.catalina.core.StandardContext.start(StandardContext.java:4357) > at > org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:823) > at > org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:807) > at > org.apache.catalina.core.StandardHost.addChild(StandardHost.java:595) > ... > Prior to Axis 1.4, we used Axis 1.1 which works fine (undeploy then > redeploy).
