我在Websphere Liberty 16.0.0.4中运行JSF 2.2应用程序。
它使用了JSF的Myfaces 2.2实现，捆绑在com.ibm.ws.jsf.2.2_1.0.15.jar中。我正在为org.apache.myfaces.renderkit.MyfacesResponseStateManager获取ClassNotFoundException。
同样的JSF页面在WAS 9 Classic中运行良好，它也使用了Myfaces 2.2。
欢迎任何帮助。请参阅下面的堆栈跟踪。
谢谢，Sanjay

答案 0 :(得分：0)
jsf-2.2 Liberty功能不公开MyFaces实现类，而WebSphere Traditional profile（经典）允许访问这些内部类。在您的场景中，Spring类org.springframework.faces.webflow.FlowRenderKit正在尝试通过org.apache.myfaces.renderkit.MyfacesResponseStateManager加载内部类ClassUtils.forName，class Debounce extends React.Component {
constructor(props) {
super(props);
this.handleChange = this.handleChange.bind(this);
}
state = {
searchTerm: '',
};
setSearchTerm = debounce((searchTerm) => this.setState({ searchTerm }), 1000);
handleChange(e) {
this.setSearchTerm(e.target.value);
}
render() {
return (
<div>
<input type="text" onChange={this.handleChange} />
<div>Search Value 2: {this.state.searchTerm}</div>
</div>
);
}
}
不会在Liberty上工作，而且通常不是很好的做法。
如果您不需要与应用程序进行CDI集成，则直接捆绑MyFaces - 而不是使用Liberty jsf-2.2功能 - 应该允许此方案生效。
上提出问题可能是值得的相关答案：MyFaces and WebSphere Liberty Profile (ClassNotFoundException)
