There is also change that Eclipse Project is somehow corrupted. Usually case like this Eclipse is added some duplicated .jars in your project and those .jars are usually same as Maven Dependency .jars.

If your project look like below example there is huge change that Maven Dependencies are duplicated and should be removed manually.

 
e.g. (Project Explorer View) 
src/main/java 
src/test/java 
spring-boot-vaadin.jar 
spring-aop.jar 
Maven Dependencies 
&nbsp;&nbsp;spring-boot-vaadin.jar 
&nbsp;&nbsp;spring-aop.jar 
etc...

<h2>...and this is cure :-)</h2> 
Project/Properties/Java Build Path/Libraries 

Just remove all REPO_M2/... paths and update project.

Tomcat has different WAR deployment ways.
Some work, some don't.
Please try the following deployment methods : <ul>
<li>Automatic: Copy-paste your WAR file into ${CATALINA_HOME}/webapps. A folder with the same name will appear if everything goes right.</li>
<li>Manager Application: Upload the WAR file</li>
<li>Manager Application: Locate the WAR file</li>
</ul>
 
In my case, using the Manager Application (local URL: <a href="http://localhost:8080/manager" rel="nofollow">http://localhost:8080/manager</a>) worked. Whereas deploying using a copy-paste resulted in your error.

entityMap|blocks|key|6q11m|text|在将war文件部署到Tomcat时，我得到了这个错误。我的项目需要Java+1.8，结果只安装了Java+1.7。从我能找到的任何日志文件中看不出来。|type|unstyled|depth|inlineStyleRanges|entityRanges|data^0^^$0|$]|1|@$2|3|4|5|6|7|8|C|9|@]|A|@]|B|$]]]]

I got this error when deploying a war file to Tomcat. My project required Java 1.8, and it turned out only Java 1.7 was installed. It wasn't immediately obvious from any log file that I could find.

entityMap|blocks|key|cdva9|text|对我来说，这个问题是由于从Git中将项目签入到其他目录而导致的。选择与war文件相同的名称解决了问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data^0^^$0|$]|1|@$2|3|4|5|6|7|8|C|9|@]|A|@]|B|$]]]]

For me the problem was caused by checking the project into an other directory from Git. Choosing the same name as the war file solved the problem.

Might be super trivial but worth a check prior to waste some time. 

At my case the <code>mysql</code> service was down.

When you have a java app including JPA / Hibernate it is checking the database connection on startup. Just found out by looking into the looks where it had an entity manager error.

entityMap|blocks|key|fmt1m|text|这可能是由代码中的问题引起的。以我为例，|type|unstyled|depth|inlineStyleRanges|entityRanges|data|8dht4|I+had+Mongo+database+pointing+to+my+local(done+this+for+testing+and+forgot+to+update+it+back)+instead+of+the+one+on+EC2+which+is+the+same+machine+

This might be caused by issue in your code. In my case, for instance,
<pre><code>I had Mongo database pointing to my local(done this for testing and forgot to update it back) instead of the one on EC2 which is the same machine 
 where war file is deployed to. 
</code></pre>
How did I figured it out? I had to compare with older version of the code which works fine.

I also faced this due to Tomcat version mismatching!
According to the documentation, the default tomcat version of Grails 4.0.x is tomcat 8 but in the server that I was using had the tomcat version of 9.0.31!
in the build.gradle file I changed compile &quot;org.springframework.boot:spring-boot-starter-tomcat&quot; to provided &quot;org.springframework.boot:spring-boot-starter-tomcat&quot; and added/modified the cache plugin to compile &quot;org.grails.plugins:cache&quot;, { exclude group: &quot;org.codehaus.groovy&quot;, module: &quot;groovy-all&quot; } under dependencies block!
[Cache plugin comes with groovy-all 2.1]
It worked like a charm! Strangely, this did not cause any problems when running the app with command grails run-app

I just downloaded the Tomcat 7.0.23 package on my Ubuntu 11.10. 

I followed the instructions on a Google API website to <a href="http://code.google.com/apis/chart/interactive/docs/dev/dsl_get_started.html#webapp" rel="noreferrer">deploy their example webapp</a>. It basically consists of <code>jar</code> files placed in the <code>WEB-INF/lib</code> directory and a <code>web.xml</code> file placed in the <code>WEB-INF</code> directory. 

Yet the app is not automatically deployed and when trying to force the server to deploy it through the manager gui, I get the following message:

<pre><code>FAIL - Application at context path /myWebApp could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: 
 Failed to start component 
 [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myWebApp]]
</code></pre>

However, the JSP examples provided with Tomcat do work!

I have the same problem on Tomcat6.

So what did I do wrong ? Is this a permission problem ? (I even try to change the mod of all files to 777).
