Deploy your Java app to Cloudflare Pages
Step-by-step deployment help for Java apps on Cloudflare Pages. We fix Java-specific deployment issues, configure Cloudflare Pages, and get your app live. From $19.
Java issues we fix before deploying
Common Java problems that affect Cloudflare 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.
Cloudflare Pages deployment issues we check for
Common Cloudflare Pages problems that break Java apps in production.
Workers runtime missing Node.js APIs
AI-generated server code uses Node.js built-ins (Buffer, fs, crypto) that don't exist in the Cloudflare Workers runtime, causing build or runtime errors.
Function invocation limits exceeded
Free tier allows 100,000 function invocations per day. AI-generated SPAs that use functions for every API call burn through limits quickly in production.
KV namespace not bound in wrangler.toml
AI tools reference KV storage in code but forget to declare the KV namespace binding in wrangler.toml, causing undefined binding errors at runtime.
Request body size limited to 100MB
Cloudflare Workers have a strict 100MB request body limit. AI-generated file upload handlers don't implement chunked uploads, failing on larger files.
