Faces for Jakarta® EE

Jakarta® Faces support for VS Code: Facelets pages (*.xhtml), Expression Language and their Java beans, powered by the Faces Language Server.

Features

• Completion, hover and go to definition for tags, attributes and EL: beans, properties, methods, bundle keys, taglib functions
• Tags come from the tag libraries and composite components of your project and its jars, so PrimeFaces, OmniFaces and your own components need no setup
• Navigation through templates, includes, composite components, component ids and search expressions like @form
• Diagnostics for unknown tags and attributes, missing required attributes, EL errors and unresolved names
• Find references and call hierarchy, including the pages that use a Java method or property
• Quick fixes to declare namespaces and add required attributes, snippets for common tags

Requirements

• Java 21 or newer, from faces.java.home, JAVA_HOME, the Red Hat Java extension or PATH
• Language Support for Java by Red Hat for everything Java: beans, properties, methods, library jars. Without it, only tags, ids, paths and resource bundles work.

Tips

• Declare missing namespaces on save:

  "[facelets]": { "editor.codeActionsOnSave": { "source.addMissingImports": "explicit" } }
  

• Predefine prefixes for other libraries with faces.namespaces, e.g. {"o": "http://omnifaces.org/ui"}.
• If another extension claims *.xhtml, set "files.associations": { "*.xhtml": "facelets" }.
