使用普园的总结

1. 出现对已有EOS project稍作改动之后，再启动EOS server时出现

曾就此问题问过 xiaoj ，他只说Windows的系统环境变量 path 所含内容太多，但删除 path 中的部分内容使其缩短之后，问题仍然依旧。

 

 

后来与 liyp 商量不得不将 页面流中的所有 调用服务 改为 逻辑运算。

 

2. 在EOS project中使用 carrot的聚类功能时，需要在 project 的 build path ---libraries 中添加 有关carrot的 jar包。

 

添加 jar包有学问，点击“add external jar package” 寻找到 解压carrot2-java-api-3.3.0-dev 的目录，将carrot2-core.jar 包含到project中。

另外，把 解压 解压carrot2-java-api-3.3.0-dev 的目录下 lib 目录拷贝到 project 下的 Web --- WEB-INF之下，缺省情况下，在Web --- WEB-INF之下就有一个名字为 lib的节点 但其中无内容。  需要注意的是不可以把 carrot2-java-api-3.3.0-dev 的目录下 lib 目录拷贝到 project 下的 根目录下，然后再利用project 的 build path ---libraries 中的 “add internal jar”把根目录下的lib目录添加到 与 jre库同级 ，这样做会产生以下错误信息

 

 

it is indirectly referenced from required .class files

only a type can be imported

org.codehaus.jackson.annotate.JSONMethod

the type org.corrot2.cluster cannot  be resolved
