我在使用JSF 2.2和Primefaces 5加载主题时遇到错误。我有以下bean：
package beans;
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean(name = "themeSwitcher")
@SessionScoped
public class ThemeSwitcher implements Serializable {
private String theme;
public ThemeSwitcher () {
theme = "afterdark";
}
public String getTheme() {
return theme;
}
public void setTheme(String theme) {
this.theme = theme;
}
}
完美无缺。当我尝试将其更改为@Named以便能够将其注入我的其他bean时出现此错误：
FATAL: JSF1073: javax.faces.FacesException caught during processing of RENDER_RESPONSE 6 : UIComponent-ClientId=, Message=Error loading theme, cannot find "theme.css" resource of "primefaces-" library

我正在使用Netbeans 8，我已经将这些罐子添加到了库中。我也尝试将它们放在WEB-INF / lib文件夹中，但它没有帮助。有什么建议吗？
答案 0 :(得分：0)
为什么不使用@ManagedProperty注释注入bean呢？例如，在二级课程中：
@ManagedBean
@ViewScoped
public class Foo extends Bar {
@ManagedProperty(value="#{themeSwitcher}")
private ThemeSwitcher themeSwitcher;
