先贴一下代码吧。jsp页面中代码如下：
- Java code
<h:outputText value="掌握外语语种：" /><h:selectManyListbox value="#{ResumeBean.language}"> <f:selectItems value="#{ResumeBean.languageMap}" /></h:selectManyListbox>这里是想使用托管的bean给前台注入值。后台的java代码如下：
- Java code
private static Map<String, String> languageMap = null; public static Map<String, String> getLanguageMap() { languageMap = new LinkedHashMap<String, String>(); languageMap.put("英语", "英语"); languageMap.put("日语", "日语"); languageMap.put("俄语", "俄语"); languageMap.put("德语", "德语"); return languageMap; } public static void setLanguageMap(Map<String, String> languageMap) { ResumeBean.languageMap = languageMap; }但是在运行jsf页面的时候，总是报错，检查了很久，不知道什么原因。错误代码如下：
- Java code
