How to gain access to Tomcat Manager Web Application
To support these capabilities, Tomcat 6 includes a web application (installed by default on context path /manager) that supports the following functions: Deploy a new web application from the uploaded contents of a WAR file. Deploy a new web application, on a . Deploy a web application directory or ".war" file located on the Tomcat server. If no path is specified, the path and version are derived from the directory name or the war file name. The war parameter specifies a URL (including the file: scheme) for either a directory or a web.

This guide describes what you should be aware of when you want to migrate an existing Tomcat application to run on Azure App Service using Tomcat 8. If you can't meet any of the pre-migration requirements, see the following companion migration guides:. App Service offers specific versions of Tomcat on specific versions of Java. To ensure compatibility, migrate your application to one of the supported versions of Tomcat and Java in its current environment before you proceed with any of the remaining steps.
Be sure to fully test the resulting configuration. Use the latest stable release of your Linux distribution in such tests. To obtain your current Java version, sign in to your production server and run the following command:. To obtain the current version used by Azure App Service, download Zulu 8 if you intend to use the Java 8 runtime or Zulu 11 if you intend to use the Java 11 runtime. To obtain your current Tomcat version, sign in to your production server and run the following command:.
To obtain the current version used by Azure App Service, download Tomcat 8. Some such resources may require migration or reconfiguration. In context. In server. Datasources are JNDI resources with the type attribute set to javax, tomcat war manage app download. For each datasource, document the following information:.
It tomcat war manage app download feasible to document every possible external dependency in this guide. It's your team's responsibility to verify that you can satisfy every external dependency of your application after the migration. Check all properties and configuration files on the production server s for any secret strings and passwords. Be sure to check server. You may also find configuration files containing passwords or credentials inside your application.
Document all the certificates used for public SSL endpoints or communication with backend databases and other systems. You can view all certificates on the production server s by running the following command:. Any usage of the file system on the application server will require reconfiguration tomcat war manage app download, in rare cases, architectural changes. You may identify some or all of the following scenarios. If your application currently serves static content for example, via an Apache integrationyou'll need an alternate location for that static content.
We've provided a sample implementation for your use at Uploading and CDN-preloading static content with Azure Functions. For files that are frequently written and read by your application such as temporary data filesor static files that are visible only to your application, you can mount Azure Storage into the App Service file system.
To identify the session persistence manager in use, inspect the context. Tomcat's built-in PersistentManager implementations, such as StandardManager or FileStore aren't designed for use with a distributed, scaled platform such as App Service. Because App Service may load balance among several instances and transparently restart any instance at any time, persisting mutable state to a file system isn't recommended.
If session persistence is required, you'll need to use an alternate PersistentManager implementation that will write to an external data store, such as Pivotal Session Manager with Redis Cache. For more information, see Use Redis as a session cache with Tomcat. Certain production scenarios may require additional changes or impose additional limitations.
While such scenarios can be infrequent, tomcat war manage app download, it is important to ensure that they are either inapplicable to your application or correctly resolved. Scheduled jobs, such as Quartz Scheduler tasks or cron jobs, can't be used with App Service.
App Service will not prevent you from deploying an application containing scheduled tasks internally. However, if your application is scaled out, the same scheduled job may run more than once per scheduled period. This situation can lead to unintended consequences. If your application contains any code with dependencies on the host OS, then you'll need to refactor it to remove those dependencies.
Separator or Paths. Tomcat clustering isn't tomcat war manage app download on Azure App Service. Instead, you can configure and manage scaling and load balancing through Azure App Service without Tomcat-specific functionality, tomcat war manage app download.
You can persist session state to an alternate location to make it available across replicas. For more information, tomcat war manage app download, see Identify session persistence mechanism.
You will need to migrate elsewhere or eliminate any processes running outside of Application Server, such as monitoring daemons. If your application requires additional connectors, such as the AJP connector, don't use App Service. MemoryRealm requires a persisted XML file. You tomcat war manage app download have to modify the pathName parameter accordingly.
To determine whether MemoryRealm is currently used, inspect your server. App Service performs session offloading outside of the Tomcat runtime. Therefore, you can't use SSL session tracking, tomcat war manage app download. In the pre-migration you'll likely have identified secrets and external dependencies, such as datasources, in server.
For each item thus identified, replace any username, password, connection string or URL with an environment variable. From the list of available service plans at App Service pricingselect the plan whose specifications meet or exceed those of the current production hardware. We recommend using Premium or higher plans for Java applications. For more information, see Set up staging environments in Azure App Service. Then, create the App Service plan.
For more information, see Manage an App Service plan in Azure. While it's possible to deploy multiple WAR files to a single web app, this is highly undesirable. Deploying multiple WAR files to a single web app prevents each application from scaling according to its own usage demands. It also adds complexity to subsequent deployment pipelines. If multiple applications need to be available on a single URL, consider using a routing solution such as Azure Application Gateway.
If you can't use the Maven plugin, you'll need to provision the Web App through other mechanisms, such as:. Once the Web App has been created, use one of the available deployment mechanisms to deploy your application. If your application requires specific runtime options, use the most appropriate mechanism to specify them.
Use Application Settings to store any secrets specific to your application. If you intend to use the same secret s among multiple applications or require fine-grained access policies and audit capabilities, tomcat war manage app download, use Azure Key Vault instead. If your application will be visible on a custom domain, you'll need to map your web application to it.
All certificates for communicating with backend systems, such as databases, need to be made available to App Service. Follow these steps to migrate data sources. Migrate any additional server-level classpath dependencies by following the same steps as for data source JAR files.
If you're following the recommended architecture of one WAR per webapp, consider migrating server-level classpath libraries and JNDI resources into your application. This will significantly simplify component governance and change management. To execute scheduled jobs on Azure, consider using a Timer trigger for Azure Functions.
You don't need to migrate the job code itself into a function. The function can simply invoke a URL in your application to trigger the job.
Alternatively, you can create a Logic app with a Recurrence trigger to tomcat war manage app download the URL without writing any code outside your application. To prevent malicious use, you'll likely need to ensure that the job invocation endpoint requires credentials.
In this case, the trigger function will need to provide the credentials. Finally, you'll need to restart your Web App to apply all configuration changes. Upon completion of the restart, verify that your application is running correctly.
Now that you have your application migrated to Azure App Service you should verify that it works as you expect. Once you've done that we have some recommendations for you that can make your application more Cloud native.
Consider tomcat war manage app download Deployment Slots for reliable deployments with zero downtime. Design and implement a DevOps strategy.
In order to maintain reliability while increasing tomcat war manage app download development velocity, consider automating deployments and testing with Azure Pipelines. If using Deployment Slots, you can automate deployment to a slot and the subsequent slot swap. Design and implement a business continuity and disaster recovery strategy. For mission-critical applications, consider a multi-region deployment architecture, tomcat war manage app download. Skip to main content.
