Deploy your Java app to GitHub Pages
Step-by-step deployment help for Java apps on GitHub Pages. We fix Java-specific deployment issues, configure GitHub Pages, and get your app live. From $19.
Java issues we fix before deploying
Common Java problems that affect GitHub Pages deployments.
SQL injection via string concatenation
Building SQL queries with string concatenation instead of PreparedStatement or parameterized JPA queries, allowing attackers to manipulate database operations.
Missing input validation
Controller endpoints accept request bodies without Bean Validation annotations (@Valid, @NotNull, @Size), allowing malformed data into business logic.
Thread safety issues
Mutable shared state accessed from multiple threads without synchronization, volatile, or concurrent collections — causing race conditions in production.
Resource leaks
Database connections, streams, and file handles opened without try-with-resources, leading to connection pool exhaustion and OutOfMemoryErrors.
GitHub Pages deployment issues we check for
Common GitHub Pages problems that break Java apps in production.
Client-side routing returns 404 on refresh
React Router and other SPA routers break on page refresh because GitHub Pages doesn't support URL rewrites. Only the root index.html is served for the base path.
API routes have no server to run on
AI-generated Next.js or Express backends can't run on GitHub Pages. There's no server-side execution — only static HTML, CSS, and JavaScript are served.
Base path not configured for project sites
Project sites deploy to username.github.io/repo-name, but AI tools build with root (/) as the base path, breaking all asset and route references.
Custom domain DNS propagation issues
CNAME file missing from the build output or DNS records misconfigured, causing the custom domain to point nowhere or show GitHub's 404 page.

Frequently asked questions
How do I deploy a Java app to GitHub Pages?
We handle Java deployments to GitHub Pages end to end. Start with our code audit ($19) to identify deployment blockers specific to your Java project, then we configure GitHub Pages, fix issues, and get your app live in production.
What Java issues affect GitHub Pages deployments?
Java projects commonly have sql injection via string concatenation and missing input validation. On GitHub Pages, these combine with client-side routing returns 404 on refresh and api routes have no server to run on to cause deployment failures.
Can SpringCode deploy my Java project to GitHub Pages?
Yes. We specialize in deploying Java applications to GitHub Pages. We audit your codebase for Java-specific issues, configure GitHub Pages correctly, and handle the full deployment so your app runs reliably in production.
What does Java deployment to GitHub Pages cost?
Our code audit ($19) identifies all GitHub Pages deployment blockers in your Java project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
