Frequently Asked Questions
What is Java?
Java runs server-side applications on servlet containers and application servers (Tomcat, Jetty, WildFly) and through frameworks such as Spring Boot. It is common in enterprise, banking and public-sector sites. Detection relies on server banners, the JSESSIONID cookie and .jsp links.
How do you detect Java on a website?
Our scanner analyzes multiple technical signals including HTTP response headers: server containing "Apache-Coyote|Apache Tomcat|Jetty|WildFly|GlassFish|Payara|Undertow|WebLogic|WebSphere|Resin"; x-powered-by containing "Servlet|JSP|JSF|JBoss|Tomcat|Jetty" (high-confidence tier) and Cookies named like "JSESSIONID" (medium-confidence tier) to identify Java usage with high accuracy.
Which websites use Java?
Thousands of websites use Java across various industries. Our real-time scanner continuously discovers new Java deployments — use the search above to detect any website.
Is Java popular?
Java is a widely adopted Framework in the web infrastructure space. Our scanner detects it regularly across scanned domains.
How We Detect Java
- HTTP response headers: server containing "Apache-Coyote|Apache Tomcat|Jetty|WildFly|GlassFish|Payara|Undertow|WebLogic|WebSphere|Resin"; x-powered-by containing "Servlet|JSP|JSF|JBoss|Tomcat|Jetty" (high-confidence tier)
- Cookies named like "JSESSIONID" (medium-confidence tier)
- Signal weights for Java: 85 points per high-tier match, 55 per medium, 25 per low — a site needs 60+ points before Java is reported.
