# Google Web Toolkit ## Identification Google Web Toolkit uses `.gwt.xml` module descriptors to describe modules and build-time relationships in Java-based web projects. ## Notebook evidence [[Scanned_20260730-1806#Page 18 — `Scanned_20260730-1806.pdf`, PDF page 18|PDF page 18]] records `Jsr305_annotations.gwt.xml` inside an APK and asks what GWT and JSR mean. ## Evidentiary boundary A `.gwt.xml` resource inside an APK may be inherited dependency metadata. It does not prove that the app hosts a GWT application or contacted a web service. The transcribed `//third_party/...` string is a source-tree path, not an HTTP/HTTPS URL. ## Relationships [[JSR 305]] · [[Software Composition Analysis]] · [[Android Package]].
