What you can do is the following;

Add a file called <code>ROOT.xml</code> in <code>&lt;catalina_home&gt;/conf/Catalina/localhost/</code>

This ROOT.xml will override the default settings for the root context of the tomcat installation for that engine and host (Catalina and localhost).

Enter the following to the ROOT.xml file;

<pre><code>&lt;Context 
 docBase="&lt;yourApp&gt;" 
 path="" 
 reloadable="true" 
/&gt;
</code></pre>

Here, <code>&lt;yourApp&gt;</code> is the name of, well, your app.. :)

And there you go, your application is now the default application and will show up on <code>http://localhost:8080</code>

However, there is one side effect; your application will be loaded twice. Once for <code>localhost:8080</code> and once for <code>localhost:8080/yourApp</code>. To fix this you can put your application OUTSIDE <code>&lt;catalina_home&gt;/webapps</code> and use a relative or absolute path in the ROOT.xml's docBase tag. Something like this;

<pre><code>&lt;Context 
 docBase="/opt/mywebapps/&lt;yourApp&gt;" 
 path="" 
 reloadable="true" 
/&gt;
</code></pre>

And then it should be all OK!

The below trick worked for me.

1) Comment/delete the below configuration from server.xml file (inside conf folder) of tomcat.

2) Delete the existing ROOT folder (If any) residing inside tomcat webapps folder. And rename your war (e.g: test.war ) file to ROOT.war.

Remember that while renaming war file to ROOT.war "ROOT" should be in caps.

Limitation: You can deploy only one application inside one tomcat instance.

blocks|key|255690|text|我面对这个问题一个月了，把上下文标签放在server.xml里是不安全的，它会影响所有其他主机的上下文元素的部署，对于大型应用程序，它会导致连接错误，也不能很好地隔离，例如，你可能通过文件夹名称domain2.com/domain1Folder访问其他网站!！还加载了两次数据库会话连接！另一种方法是放入具有上下文标签和完整路径的ROOT.xml文件，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|255691|+<Context+path=""+docBase="/var/lib/tomcat7/webapps/ROOT"+/>|code-block|syntax|javascript|255692|在conf/catalina/webappsfoldername中，将war文件作为ROOT.war部署到webappsfoldername中，并指定主机|255693|+<Host+name="domianname"++appBase="webapps2"+unpackWARs="true"++autoDeploy="true"++xmlValidation="false"+xmlNamespaceAware="false"+>

I faced this problem for one month,Putting context tag inside server.xml is not safe it affect context elements deploying for all other host ,for big apps it take connection errors also not good isolation for example you may access other sites by folder name domain2.com/domain1Folder !! also database session connections loaded twice !
the other way is put ROOT.xml file that has context tag with full path such :

<pre><code> &lt;Context path="" docBase="/var/lib/tomcat7/webapps/ROOT" /&gt;
</code></pre>

in conf/catalina/webappsfoldername
and deploy war file as ROOT.war inside webappsfoldername
and also specify host 
 such 

<pre><code> &lt;Host name="domianname" appBase="webapps2" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false" &gt;

 &lt;Logger className="org.apache.catalina.logger.FileLogger"
 directory="logs" prefix="localhost_log." suffix=".txt"
 timestamp="true"/&gt;
&lt;/Host&gt;
</code></pre>

In this approach also for same type apps user sessions has not good isolation !
you may inside app1 if app1 same as app2 you may after login by server side session automatically can login to app2 ?!
So you have to keep users session in client side cache and not with jsessionid !
we may change engine name from localhost to solve it.
but let say playing with tomcat need more time than play with other cats!

It's not recommended to update the server configuration like server.xml or ROOT.xml.

You can put a context.xml configuration file under your web-application META-INF directory, with the context path setting included. This will override the default server setting?

Simplest and flexible solution is below:
Inside ${Tomcat_home}/config/server.xml

Change the autoDeploy="false" deployOnStartup="false" under Host element like below This is must.

<pre><code>&lt;Host name="localhost" appBase="webapps"
 unpackWARs="true" autoDeploy="false" deployOnStartup="false"&gt;
</code></pre>

Add below line under Host element.

<pre><code>&lt;Context path="" docBase="ServletInAction.war" reloadable="true"&gt;
 &lt;WatchedResource&gt;WEB-INF/web.xml&lt;/WatchedResource&gt;
 &lt;/Context&gt;
</code></pre>

With the above approach we can add as many applications under webapps with different context path names.

I know that I can rename my webapp (or it's WAR file) to ROOT but this is a terrible way to do it, IMHO. Now I checked out the tomcat doc &amp; it says 

<blockquote>
 It is NOT recommended to place elements directly in the
 server.xml file
</blockquote>

So I tried doing it another method that it suggested.

<blockquote>
 Individual Context elements may be explicitly defined: In an
 individual file at /META-INF/context.xml inside the application files.
</blockquote>

So I created a <code>/META-INF/context.xml</code> with the following code,

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;Context antiJARLocking="true" path="/"/&gt;
</code></pre>

But after deploying when I restarted the server it still failed to load the context at "/", it still loaded it with the <code>"/&lt;WEB_APP_NAME&gt;"</code>

Any pointers helpful.

How to set the context path of a web application in Tomcat 7.0

虚拟主机

数据库

服务器

我知道我可以将我的webapp (或者它的WAR文件)重命名为根，但是这是一个糟糕的方式。现在，我查看了tomcat文档&它说不建议直接在server.xml文件中放置元素因此，我尝试了它建议的另一种方法。单独的上下文元素可以显式地定义:在应用程序文件内的/META-INF/context.xml处的单独文件中。所以我...
