Tomcat version: 8.0.24 OS RHEL 6.6
Just one war file (ascws.war) is deployed under it. We are seeing intermittent failure while deploying war file, tomcat logs indicates (zip file is empty) exception is mentioned below. We have verified file is correct (non zero), and only way to recover from error is manually delete ascws folder (from webapp folder) and restart tomcat. FYI.. ascws.war is a symbolic link to other location. ascws is a spring boot based application. We are not able to figure out what is wrong, any help is much appreciated. ========== 10-Sep-2015 09:47:32.488 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive /opt/apache-tomcat/webapps/ascws.war 10-Sep-2015 09:47:32.628 SEVERE [localhost-startStop-1] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/ascws]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:725) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:701) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:717) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:945) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1768) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: org.apache.catalina.LifecycleException: Failed to start component [org.apache.catalina.webresources.StandardRoot@1690212] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) at org.apache.catalina.core.StandardContext.resourcesStart(StandardContext.java:4845) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:4975) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 10 more Caused by: org.apache.catalina.LifecycleException: Failed to initialize component [org.apache.catalina.webresources.JarResourceSet@5dd3221b] at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:106) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:139) at org.apache.catalina.webresources.StandardRoot.startInternal(StandardRoot.java:699) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 13 more Caused by: java.lang.IllegalArgumentException: java.util.zip.ZipException: zip file is empty at org.apache.catalina.webresources.JarResourceSet.initInternal(JarResourceSet.java:96) at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:102) ... 16 more Caused by: java.util.zip.ZipException: zip file is empty at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.<init>(Unknown Source) at java.util.zip.ZipFile.<init>(Unknown Source) at java.util.jar.JarFile.<init>(Unknown Source) at java.util.jar.JarFile.<init>(Unknown Source) at org.apache.catalina.webresources.JarResourceSet.initInternal(JarResourceSet.java:88) ... 17 more 10-Sep-2015 09:47:32.630 SEVERE [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Error deploying web application archive /opt/apache-tomcat/webapps/ascws.war java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/ascws]] at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:729) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:701) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:717) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:945) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1768) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) 10-Sep-2015 09:47:32.631 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Deployment of web application archive /opt/apache-tomcat/webapps/ascws.war has finished in 142 ms ========== Regards, Prashant
