WSO2 Enterprise Integrator 6.0.0无法找到snappy-java jar

Question

按照https://docs.wso2.com/display/EI600/Quick+Start+Guide中的快速入门指南

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

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,如 https://docs.wso2.com/display/ESB500/Quick+所示启动+指南

Answer 1

尝试将此版本的 snappy-java 放入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。
