What does an Apache Tomcat developer do?
An Apache Tomcat developer builds, deploys, and manages Java web applications on the Apache Tomcat servlet container. This role focuses on configuring Context descriptors and using deployment mechanisms to install WAR files or exploded directories into a Host appBase. The developer controls the application lifecycle by starting, stopping, reloading, and undeploying services through the Tomcat Manager interface or API.
- Package Java web applications into WAR files or prepare exploded directories for static deployment into the Host appBase. Use Apache Ant targets within the Tomcat Client Deployer toolchain to compile source code, validate the structure, and generate deployment-ready artifacts that match the target server version.
- Write and maintain Context descriptor XML files to define specific configuration settings for each deployed application. Place these descriptors in the correct location, such as the META-INF directory or the server conf folder, to ensure the servlet container applies the right resource links, environment entries, and security constraints at startup.
- Execute lifecycle commands via the Tomcat Manager HTML GUI or its URL-based HTTP API to deploy, undeploy, reload, start, and stop running applications. Monitor the server response to confirm successful state changes and troubleshoot deployment failures by reviewing catalina logs and validating the manager access credentials.
How to hire an Apache Tomcat developer on Upwork
Step 1: Post a job
Describe your Java web application deployment needs in a few sentences and let Job Post Generator powered by Uma™, Upwork's Mindful AI draft a complete job post for the role. You can write a new post, update a saved draft, or reuse an existing post to attract qualified candidates.
- Specify that the freelancer must package WAR files and configure Context descriptors for your specific Tomcat version.
- List required experience with Tomcat Manager for dynamic deployment, reloading, and undeploying applications on live servers.
- Clarify if the role involves using Apache Ant and Tomcat Client Deployer to compile and validate web applications before installation.
Step 2: Evaluate candidates
Look for portfolios showing successful deployment of Java web apps and correct XML configuration for Tomcat Contexts. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.
- Verify candidates have authored Context descriptor files that define resource links and environment entries for deployed applications.
- Check for evidence of managing application lifecycles, including starting, stopping, and reloading services without server restarts.
- Confirm experience placing exploded web application directories into the Host appBase for static deployment scenarios.
Step 3: Interview your top choices
Discuss specific workflows for deploying updates and handling configuration changes in production environments. Interviews can be scheduled and conducted within Upwork Messages with an immediate transcript and summary after each one.
- Ask how they troubleshoot deployment failures when using the Tomcat Manager HTML GUI or URL-based API.
- Request examples of how they structure WAR files to ensure compatibility with different Tomcat server versions.
- Inquire about their process for validating web applications using Ant targets before pushing code to staging or production.
Step 4: Agree on scope and begin work
Define clear milestones for packaging, deploying, and configuring your Java web applications on the target server. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Set a milestone for delivering a packaged and validated WAR file suitable for deployment to your specified Tomcat instance.
- Require the freelancer to submit correct Context descriptor XML configurations as part of the final deliverable.
- Include a task for performing initial application lifecycle actions, such as deploy and start, to verify the installation works.
