JGAS package content

When working with JGAS, it is helpful to know the files contained in the installation, and their function.

JGAS installation directory structure

Your JGAS installation directory, FGLDIR/web_utilities/jgas, contains a directory structure with files as shown:

│─── PRODUCTINFO
│─── VERSION
│─── WebContent
│     │─── index.jsp
│     │─── META-INF
│     │     │─── MANIFEST.MF
│     │     │─── services
│     │     │     │─── javax.servlet.ServletContainerInitializer
│     │─── WEB-INF
│     │     │─── as.xcf
│     │     │─── lib
│     │     │     │─── jgas.jar
│     │     │─── mimetypes.properties
│     │     │─── web.xml
│─── jgas-standalone.jar

The files listed in Table 1 are the most important ones.

Important:

All installation files are subject to change when an upgrade occurs. It is therefore not recommended to modify any files in the installation directory to avoid having to reapply your modifications each time the product is upgraded.
