Embedded error: Server returned HTTP response code: 403 for URL: http://localhost:8080/manager/deploy?path


You are not authorized to view this page.
If you have already configured the Manager application to allow access and you have used your browser's back button, used a saved book-mark or similar then you may have triggered the cross-site request forgery (CSRF) protection that has been enabled for the HTML interface of the Manager application. You will need to reset this protection by returning to the main Manager page. Once you return to this page, you will be able to continue using the Manager appliction's HTML interface normally. If you continue to see this access denied message, check that you have the necessary permissions to access this application.
If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.
For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>
Note that for Tomcat 6.0.30 onwards, the roles required to use the manager application were changed from the single manager role to add the following four roles. (The manager role is still available but should not be used as it avoids the CSRF protection). You will need to assign the role(s) required for the functionality you wish to access.
  • manager-gui - allows access to the HTML GUI and the status pages
  • manager-script - allows access to the text interface and the status pages
  • manager-jmx - allows access to the JMX proxy and the status pages
  • manager-status - allows access to the status pages only
The HTML interface is protected against CSRF but the text and JMX interfaces are not. To maintain the CSRF protection:
  • users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
  • if the text or jmx interfaces are accessed through a browser (e.g. for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.
For more information - please see the Manager App HOW-TO.


You get the error message above when you try to use Maven to deploy your war-application to Tomcat or try to put http://localhost:8080/manager/deploy?path=yourWar.war in the browser. If you install Tomcat windows installer you will have the following pre-configuration in your tomcat-users.vml file ( located under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf ). You have to change or add the following:



<tomcat-users>
<role rolename="manager"/>
<user username="admin" password="edison" roles="manager"/>

....
</tomcat-users>





In your POM.xml you should have the following:


<!--  tomcat-server -->
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<configuration>
<server>tomcat-server</server>
<path>/arbetsformedling</path>
</configuration>
</plugin>



In order to get the maven deploy via the following at command line:
$mvn tomcat:deploy 
or
$mvn tomcat:undeploy
