Tomcat6.x部署MyFaces包冲突问题

ApacheJavaWebTomcatSpring 
阅读更多

项目环境：JSF2.0(MyFaces2.0.1)+RichFaces+Tomahawk1.1.9+Spring2.0+Hibernate3.2.x

（附apache官网上说tomahawk只支持到JSF1.2，但是我在JSF2.0的环境下测试可用，不知道后续是否会有问题）

 

启动Tomcat的时候报以下错误，百思不得其解

最后解决方式：删除项目lib下的el-api.jar、servlet-api.jar后启动Tomcat

原因：tomcat6.x下的lib包中已经包括了这两个jar包（见图2），即常见的包冲突问题

 

有人会问：把这两个jar包从classpath中remove掉就不行了么？

 

因为项目中有用到以下代码：

UICommand command = (UICommand) actionEvent.getComponent();
MethodExpression methodExpression = command.getActionExpression();

依赖el-api.jar；

public class DefaultApplicationSetupListener implements ServletContextListener {

	public void contextInitialized(ServletContextEvent event) {
		SpringContainer container = new SpringContainer(event.getServletContext());
		Application.getInstance().setContainer(container);
	}

	public void contextDestroyed(ServletContextEvent arg0) {
	}

}

 

依赖servlet-api.jar；所以不能删除掉。

 

（注：java编译期不能依赖tomcat下的jar包，启动tomcat的时候又会发生jar包冲突，如果项目最后要部署在tomcat下，则可以在打包部署的时候通过Ant来有选择的添加依赖的jar包）
