我正在尝试使用 jsf 在我的项目中上传图片。
xhtml页面：
<ui:composition template="./template/templateAdmin.xhtml">
<ui:define name="content">
<f:view>
<h:form enctype="multipart/form-data">
<table border="0" width="100%" cellpadding="0" cellspacing="0" id="content-table">

</h:form>
</f:view>
</ui:define>
</ui:composition>
豆：
public void handleFileUpload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
如果我建立在一个简单的项目上，它会完美运行。但是当我将此代码包含在ui:define标签中时。它不起作用。
我该如何解决。
谢谢。
