When used to select a web application ". Here is an example of installing an application using a Context configuration ". The name of the WAR file without the ".
Use the Browse button to select a WAR file to upload to the server from your local desktop system. If a war file of the same name already exists in your Host's appBase the upload will fail.
Either undeploy the existing war file from your Host's appBase or upload the new war file using a different name. The war file upload or install failed with a Java Exception.
The exception message will be listed. For security when untrusted users can manage web applications, the Host deployXML flag can be set to false. This prevents untrusted users from installing web applications using a configuration XML file and also prevents them from installing application directories or ".
The context paths for all currently running web applications must be unique. Therefore, you must either undeploy the existing web application using this context path, or choose a different context path for the new one. An exception was encountered trying to start the new web application. If the Host deployXML flag is set to false this error will happen if an attempt is made to install a web application directory or ".
The find leaks diagnostic triggers a full garbage collection. It should be used with extreme caution on production systems. The find leaks diagnostic attempts to identify web applications that have caused memory leaks when they were stopped, reloaded or undeployed. Results should always be confirmed with a profiler.
The diagnostic uses additional functionality provided by the StandardHost implementation. It will not work if a custom host is used that does not extend StandardHost. This diagnostic will list context paths for the web applications that were stopped, reloaded or undeployed, but which classes from the previous runs are still present in memory, thus being a memory leak.
In addition, you can request an existing application to reload itself, even if you have not declared it to be reloadable in the Tomcat server configuration file. A default Tomcat installation includes the Manager. To add an instance of the Manager web application Context to a new host install the manager. Here is an example:. If you have Tomcat configured to support multiple virtual hosts websites you would need to configure a Manager for each. It would be quite unsafe to ship Tomcat with default settings that allowed anyone on the Internet to execute the Manager application on your server.
Therefore, access to the Manager application is completely disabled by default. You can find the role names in the web. The available roles are:. To maintain the CSRF protection:. Note that JMX proxy interface is effectively low-level root-like administrative interface of Tomcat. One can do a lot, if he knows what commands to call. You should be cautious when enabling the manager-jmx role. As the majority of this document describes the commands of plain textual interface, let the role name for further example to be manager-script.
The first time you attempt to issue one of the Manager commands described in the next section, you will be challenged to log on using BASIC authentication.
The username and password you enter do not matter, as long as they identify a valid user in the users database who possesses the role manager-script. In addition to the password restrictions the Manager web application could be restricted by the remote IP address or host by adding a RemoteAddrValve or RemoteHostValve. See valves documentation for details. Here is an example of restricting access to the localhost by IP address:.
All commands that the Manager application knows how to process are specified in a single request URI like this:. In the illustrations below, customize the host and port appropriately for your installation. The first line of the response will begin with either OK or FAIL , indicating whether the requested command was successful or not. In the case of failure, the rest of the first line will contain a description of the problem that was encountered.
Some commands include additional lines of information as described below. Internationalization Note - The Manager application looks up its message strings in resource bundles, so it is possible that the strings have been translated for your platform. The examples below show the English version of the messages. Upload the web application archive WAR file that is specified as the request data in this HTTP PUT request, install it into the appBase directory of our corresponding virtual host, and start , using the directory name or the war file name without the.
Otherwise, the response will start with FAIL and include an error message. Possible causes for problems include:.
The context paths for all currently running web applications must be unique. Therefore, you must undeploy the existing web application using this context path, or choose a different context path for the new one. The update parameter may be specified as a parameter on the URL, with a value of true to avoid this error. In that case, an undeploy will be performed on an existing application before performing the deployment.
An exception was encountered trying to start the new web application. Deploy and start a new web application, attached to the specified context path which must not be in use by any other web application.
This can be used to deploy a previously deployed web application, which has been deployed using the tag attribute. Note that the work directory for the Manager webapp will contain the previously deployed WARs; removing it would make the deployment fail. Deploy a web application directory or ".

The URL specified by the war parameter must identify a directory on this server that contains the "unpacked" version of a web application, or the absolute URL of a web application archive WAR file that contains this application. Correct the value specified by the war parameter.
The URL for the directory or web application that you specified was not valid. The context path must start with a slash character. If the Host deployXML flag is set to false this error will happen if an attempt is made to deploy a web application directory or ". List the context paths, current status running or stopped , and number of active sessions for all currently deployed web applications. A typical response immediately after starting Tomcat might look like this:.
Signal an existing application to shut itself down and reload. If you have made changes to your web. An exception was encountered trying to restart the web application. Check the Tomcat logs for the details. Currently, application reloading to pick up changes to the classes or web.
It only works when the web application is deployed from an unpacked directory. If you are using a WAR file, you should undeploy and then deploy or deploy with the update parameter the application again to pick up your changes.
If an error occurs, the response will start with FAIL and include an error message. An exception was encountered trying to enumerate the system properties. List the global JNDI resources that are available for use in resource links for context configuration files. If you specify the type request parameter, the value must be the fully qualified Java class name of the resource type you are interested in for example, you would specify javax.
If you do not specify the type request parameter, resources of all types will be returned. Depending on whether the type request parameter is specified or not, the first line of a normal response will be:. Asked 9 years, 9 months ago. Active 3 years, 1 month ago. Viewed 5k times.
