Tomcat failing to deploy .war
71,134
As the above comment shows, the problem turned out to be that the application web.xml referenced a java class in a servlet definition. The problem was corrected by making sure the application actually contained that class. The missing jar file was located and put in the WEB-INF/lib directory.

I'm trying to follow this tutorial on creating a simple REST web service, however I get to deploying it on tomcat and it throws an exception:
FAIL - Application at context path /restful could not be started FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/restful]]
I've looked around for a solution and found this question and this one and they make me think that it's a servlet-mapping problem however I'm not sure how to fix it!
Here is my log file:
18/12/2012 9:57:16 AM org.apache.catalina.startup.HostConfig deployWAR SEVERE: Error deploying web application archive /opt/tomcat7/webapps/restful.war java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/restful]] at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:904) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:877) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:633) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:977) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1655) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619)
here is my web.xml file:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" version="3.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <servlet> <servlet-name>RestfulContainer</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.mcnz.ws</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>RestfulContainer</servlet-name> <url-pattern>/resources/*</url-pattern> </servlet-mapping> </web-app>
and at the risk of giving you all far too much information, here is a ls of my folder structure:
