Tomcat Error: WARNING: Failed to retrieve JNDI naming context for container

Question

I am encountering the following error within the catalina.2013-12-31.log file on the Tomcat70/logs/ folder, when I attempt to start a recently deployed web application on Tomcat 7.

Dec 31, 2013 10:11:20 AM org.apache.catalina.deploy.NamingResources cleanUp
WARNING: Failed to retrieve JNDI naming context for container [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/crm]] so no cleanup was performed for that container

My application is a JDK7 Web Application. I have tried to look for similar questions and tried some suggestions such as restarting the server (in order to get to clear some XML files), but it did not work.

Any ideas please?

Update:

This is what I have in web.xml:

Server's context.xml in /Tomcat70/conf/:

<?xml version='1.0' encoding='utf-8'?>
<Context>
   <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>

Answer 1

The next solution worked for me:

Edit server.xml and remove (near the end of the file):

<Context docBase="xxx" path="/xxx" reloadable="true" source="org.eclipse.jst.j2ee.server:xxx"/>

That was a reference to a removed application.

Answer 2

open server configuration by double-clicking on the server name. after that check the checkbox of "Publish module contexts to separate XML files". and then restart the server

Sometimes, It's worked by removing and adding the server will resolves this issue

Answer 3

Had the same problem after setting up a complete new eclipse. Couldn´t get webapps running after fresh checkout.

In my case I had to set the "Targeted Runtimes" in the project-properties:

After that you can see the library in your Project:

Answer 4

It might due to java is corrupted, uninstall the java and install the new java version. it worked for me..

Answer 5

I had the same problem.

I was using Tomcat 8.5, and I used JNDI to configure access to an MySQL database, I used the MySQL-connector jar version 8, in my java application,

I solve it by using MySQL-connector jar version 5.

Answer 6

I had the same Error today. Then I performed a Clean on Tomcat Server, which told me there are several Maven POMs missing. So I performed a Maven Update Project (Eclipse: Right Click on Project -> Maven -> Update Projects.. -> Select your needed Projects). This solves the Problem for me.

Answer 7

Restart Tomcat.

Mine got broken after the test servlet caused exceptions.

Answer 8

Mine went away after cleaning Tomcat server.

Answer 9

May be this is the old question... but we can become lesson learned for others...

I got the same errors... and I removed runtime from the server, I remove all the repositories in .m2/repositories, Maven update, compile and it works

Answer 10

I removed my server and re add it . worked

Answer 11

I got this error when Eclipse overwrote my server.xml, particularly removing JNDI dependancy from one of my contexts:

        <Context
            docBase="myapp"
            path="/myapp"
            reloadable="true"
            source="org.eclipse.jst.j2ee.server:myapp"
        >
            <Resource
                name="jdbc/myDataSource"
                auth="Container"
                type="javax.sql.DataSource"
                ... />
        </Context>

The obvious solution - modify "Servers"-> "Tomcat v7" -> server.xml in Eclipse again manually and add 'Resource' element back.

Answer 12

That's quite a weird problem, but I resolved it by carefully checking web.xml of my project. This same problem occurred when I added 1 wrong servlet config line to web.xml and it disappeared when removed it. So check your web.xml very carefully and reverse all recent changes to it - if it makes it work, just correct the config errors you just made

Answer 13

I recently faced this strange issue and the answer is the manifest file is not of right encoding or have non visible junc character. It might happen if the file is created in unix environment and you are running it in windows.

solution is to recreate the file witj UTF-8 encoding.
