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:

Brachy

What do you have in your web.xml and Tomcat's context.xml in terms of JNDI lookups? – Najera

@Najera - Added my code in the following files in the update above – Brachy

The error seems to be warning only and its not coming from your application, but Tomcat Manager. Does it actually prevent you running your application? – Najera

@Najera - Yes the application does not start in fact. The problem seemed to have cropped up with newer development, but in reality, I just added a new servlet and some classes to the application. – Brachy

Is that the only error in Tomcat logs? Was this error present in earlier log files (i.e. when the application was still working for you?). Are there any other log files, i.e. localhost.log? I am not convinced that the above error is the problem here. – Najera

I encountered this today, running Tomcat server on Eclipse. After cleaning my project and republishing it started just fine. – Tabret

Does no one know why does errors like these originate? There must be some reason for this? – Settles

Answer 1

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

Lactescent

Worked for me. Thanks. – Stern

Anyone knows why this worked? What happened underneath? – Pastypat

Answer 2

I removed my server and re add it . worked

Dvorak

Answer 3

Mine went away after cleaning Tomcat server.

Fearful

Answer 4

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.

Including

this helped me ty – Ontiveros

Answer 5

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 6

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.

Thorlay

Could you please explain why MANIFEST file could cause such a problem? – Stedfast

I dont have a complete answer to it, but it is clear that a manifest file plays a role when deploying the archive. Simply deletion of manifest sometime helps because that triggers creation of a new with proper char spec during deployment or war packaging – Thorlay

Answer 7

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

Speos

Answer 8

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

Inherited

Answer 9

Restart Tomcat.

Mine got broken after the test servlet caused exceptions.

Answer 10

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.

Perfection

Answer 11

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

Answer 12

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:

Utgardloki

Answer 13

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.
