新浪SAE部署java war出现JAVA_SAE_Fatal_error


今天把一个war项目扔到Sina的SAE上,然后访问之,一直提示:

HTTP ERROR: 503

Problem accessing /. Reason:

    Service Unavailable

查看JVM日志如下:

  • 为了避免jar包冲突,请在上传War包至SAE环境前删除servlet-api和xml-api相关的jar包

感觉应该是jar冲突了,发现我的war包中多了dom4j.jar,删除之,reload,服务正常启动。

另外:注意sae的jre是1.6x的,如果本地是1.7或者1.8,编译的时候注意调整下。官网原话:SAE Java 环境以 OpenJDK 1.6 和 Jetty 7.4 为基础构建而成,平台运行在CentOS-6.x 64位Linux环境下。


PS:一定要注意jar冲突问题。
