按照快速入门指南进行操作 https://docs.wso2.com/display/EI600/Quick+Start+Guide

由于我使用的是Windows，我已经下载了snappy-java并将其放入\ wso2 \ analytics \ lib 但启动EI分析时仍会出现以下异常

我怀疑该指南将jar放在错误的路径上，在以前版本的ESB 5.0.0中，路径位于\ repository \ components \ lib中由...给出 https://docs.wso2.com/display/ESB500/Quick+Start+Guide

Answer 1

正确的路径是EI_HOME \ lib。当你看到＆＃34;开始轮询事件接收器＆＃34;并且错误没有出现，它有效。然后你可以继续。：）

Answer 2

尝试将此版本的snappy-java添加到lib。

http://mvnrepository.com/artifact/org.xerial.snappy/snappy-java/1.1.1.7

确保从lib和dropins目录中删除旧版本。

WSO2 Enterprise Integrator 6.0.0无法找到snappy-java jar
