About 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 We Detect Java

Our scanner identifies Java usage through the following signals:

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.
