Hi, I'm getting this error also. I'm running 4.0.4.GA, upgraged to JBossWS 1.0.2.GA and got the same error (different line #), so I switched to 1.0.1.GA and the error still shows up. I looked at my web.xml and didn't notice anything 'funny' in it. I'd deployed this same service un-annotated and it worked fine. Can someone point this newbie in the right direction? Thanks. 19:25:49,445 ERROR [MainDeployer] Could not create deployment: file:/C:/workspace/jboss-4.0.4.GA/server/default/deploy/J | SEServicesAnn.war | java.lang.ArrayIndexOutOfBoundsException: 0 | at org.jboss.ws.deployment.JSR181MetaDataBuilder.getWebParamAnnotation(JSR181MetaDataBuilder.java:377) | at org.jboss.ws.deployment.JSR181MetaDataBuilder.processWebMethod(JSR181MetaDataBuilder.java:461) | at org.jboss.ws.deployment.JSR181MetaDataBuilder.setupEndpointFromAnnotations(JSR181MetaDataBuilder.java:173) | at org.jboss.ws.deployment.JSR181MetaDataBuilderJSE.buildMetaData(JSR181MetaDataBuilderJSE.java:72) | at org.jboss.ws.deployment.ServiceEndpointDeployer.create(ServiceEndpointDeployer.java:92) | at org.jboss.ws.integration.jboss.DeployerInterceptor.create(DeployerInterceptor.java:80) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965378#...
