我是JSF的新手，我想在我的jsf頁面中添加一個高圖表，但我暗示了演示代碼，當我運行它時，它會拋出我這個.. 。如何在JSF中實現量表實體圖表
Error Parsing /index.xhtml: Error Traced[line: 185] El nombre de la entidad debe aparecer inmediatamente después de '&' en la referencia de entidades.
javax.faces.view.facelets.FaceletException: Error Parsing /index.xhtml: Error Traced[line: 185] El nombre de la entidad debe aparecer inmediatamente después de '&' en la referencia de entidades.
這是該指數

我不知道我在做什麼錯誤的代碼，希望有人能幫助我使用的Facelets
