Deploying .EAR files fails with [HDScanner] Scan failed
sysfrog Feb 12, 2008 5:52 PMHello,
I'm currently trying to create some simple template .ear file which I can use as a basis for further applications. Currently the file only contains a JSP page and a SOAP webservice. Ant is used as a make utility.
In some of the cases deployment of the .ear file works fine. However in other cases I only get an "HDScanner Scan failed" error messages. So deploying the same file sometimes works and sometimes fails.
I'm using JBoss 5 Beta 4 and the JDK 6U4. This is the output when deploying the file works:
22:38:08,546 INFO [DefaultEndpointRegistry] register: jboss.ws:context=gtest,endpoint=HelloService 22:38:08,740 INFO [TomcatDeployment] deploy, ctxPath=/gtest, vfsUrl=gtest.ear/gtest.war 22:38:10,407 INFO [WSDLFilePublisher] WSDL published to: file:/home/gst/jboss/jboss-5.0.0.Beta4/server/default/data/wsdl/gtest.ear/gtest.war/HelloServiceService51396.wsdl
And thats the output when it fails:
21:59:33,878 WARN [HDScanner] Scan failed org.jboss.deployers.spi.DeploymentException: Exception determining structure: AbstractVFSDeployment(gtest.ear) at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.deployers.structure.spi.helpers.AbstractStructuralDeployers.determineStructure(AbstractStructuralDeployers.java:85) at org.jboss.deployers.plugins.main.MainDeployerImpl.determineStructure(MainDeployerImpl.java:743) at org.jboss.deployers.plugins.main.MainDeployerImpl.addDeployment(MainDeployerImpl.java:280) at org.jboss.deployers.plugins.main.MainDeployerImpl.addDeployment(MainDeployerImpl.java:237) at org.jboss.system.server.profileservice.hotdeploy.HDScanner.scan(HDScanner.java:270) at org.jboss.system.server.profileservice.hotdeploy.HDScanner.run(HDScanner.java:221) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:181) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:205) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.RuntimeException: Error determining structure: gtest.ear at org.jboss.deployment.EARStructure.determineStructure(EARStructure.java:274) at org.jboss.deployers.vfs.plugins.structure.StructureDeployerWrapper.determineStructure(StructureDeployerWrapper.java:65) at org.jboss.deployers.vfs.plugins.structure.VFSStructuralDeployersImpl.doDetermineStructure(VFSStructuralDeployersImpl.java:194) at org.jboss.deployers.vfs.plugins.structure.VFSStructuralDeployersImpl.determineStructure(VFSStructuralDeployersImpl.java:218) at org.jboss.deployers.structure.spi.helpers.AbstractStructuralDeployers.determineStructure(AbstractStructuralDeployers.java:77) ... 14 more Caused by: java.lang.NullPointerException at org.jboss.deployment.EARStructure.determineStructure(EARStructure.java:155) ... 18 more
Any hints on what could be the cause of this problem? I've uploaded the source to http://virtual.sysfrog.org/~gst/gtest/gtest.zip and the compiled .ear file to http://virtual.sysfrog.org/~gst/gtest/gtest.ear. The strange thing is that the error does not occur in all of the cases.
