一、错误描述
执行jbpm4.4的流程demo测试（完整项目demo），报“org.jbpm.api.JbpmException: no process definition with key 'Leave'”错误异常，异常日志如下

二、解决方法
修改addResourceFromClasspath的xml流程文件路径（多加Leave目录），具体修改如下（完整项目代码下载）
//部署流程定义@b@@Test@b@public void testDeployProcessDefinition() {@b@ processEngine.getRepositoryService()@b@ .createDeployment()@b@ .addResourceFromClasspath("leave/Leave.jpdl.xml")@b@ .addResourceFromClasspath("leave/processimage.png").deploy();@b@}改为
//部署流程定义@b@@Test@b@public void testDeployProcessDefinition() {@b@ processEngine.getRepositoryService()@b@ .createDeployment()@b@ .addResourceFromClasspath("leave/Leave/Leave.jpdl.xml")@b@ .addResourceFromClasspath("leave/Leave/processimage.jpg").deploy();@b@}重新运行，日志正常
