That was pretty much a perfect question. A clear problem statement. A clear description of what you expected to happen vs. what actually happened. A clear description of what you tried. If only all posts to the users list were like this. This is an easy fix. The problem is that with no docBase defined and a path of "", tomcat is going to use a docBase of "ROOT". That means Tomcat is going to look for these files in "work/example1/ROOT" not in "work/example1". Generally, I'd recommend a slightly different directory structure. Something like: webapps-example1/ROOT.war which auto expands into webapps-example1/ROOT Mark Thank you. I know how it is when someone stop at your desk for help, but not giving you any details on what the problem is :) I followed your advices. I created separated webapps under our ${catalina.base} folder webapps-example1, webapps-example2 and so on, with a ROOT.war in each of them (what we usually do with single webapps deployment). It work... partially. I'm getting random crash with the same error as when it couldn't find the libraries. org.apache.jasper.JasperException: The absolute uri: <http://java.sun.com/jsp/jstl/core> http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application I first thought it was browser cache, but after testing a few time with wget on Tomcat itself and still getting the error, I have the feeling I'm hitting a cache inside tomcat. Why it's random, I have no clue. Next I tried the docBase approach I totally forgot about that setting after we removed them when they got a behaviour change midway in Tomcat 7 and it was recommended not to used them. With webapps-example1 and webapps-example2, everything and a configured docBase, everything worked. Multiple refresh did not cause random class not found without the docBase. However, since I have a dozen webapps, leaving 12 extra webapps folders under ${catalina.base} fell a bit cumbersome. So I tried again with the following directory structure : webapps/example1/ROOT webapps/example2/ROOT It worked like a charm too, but I noticed something that may be a priority order issues between ContextConfig and HostConfig. With this configuration: ------ <Host name="www.example1.com<http://www.example1.com>" appBase="webapps/example1" unpackWARs="true" autoDeploy="false"> <Context path="" reloadable="false" workDir="work/sourcesuite" docBase="/home/tomcat/wars/example1.war"> <JarScanner scanClassPath="false" scanBootstrapClassPath="false"/> <Resources> <PreResources className="org.apache.catalina.webresources.DirResourceSet" readOnly="true" webAppMount="/" base="/home/tomcat/CMS/example1.com" /> </Resources> </Context> </Host> ------ if I create ${catalina.base}/webapps and none of it's host appBase, I get the following error: ------ Mar 03, 2016 11:19:07 AM org.apache.catalina.startup.ContextConfig beforeStart SEVERE: Exception fixing docBase for context [] java.io.IOException: Unable to create the directory [/vol0/home/cda/servers/CDA1/webapps/mediagrif/ROOT] at org.apache.catalina.startup.ExpandWar.expand(ExpandWar.java:115) at org.apache.catalina.startup.ContextConfig.fixDocBase(ContextConfig.java:617) at org.apache.catalina.startup.ContextConfig.beforeStart(ContextConfig.java:753) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:307) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:95) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:90) at org.apache.catalina.util.LifecycleBase.setStateInternal(LifecycleBase.java:394) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:144) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1408) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1398) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) // Create the new document base directory if(!docBase.mkdir() && !docBase.isDirectory()) { throw new IOException(sm.getString("expandWar.createFailed", docBase)); } ------ The source reveal that ExpandWar try to do a mkdir but not a mkdirs .
