我用的是JBuilderx+weblogic8.1
在windows2000下能通过编译，在weblogic builder也能通过
但在widows xp 中，用JBuilerx却不能，报错误如下;

"ESM.jar": <2004-5-5 下午23时54分00秒 CST> <Warning> <EJB> <BEA-010202> <Call-by-reference is not enabled for the EJB 'GetESM'. The server will have better performance if it is enabled.

主要是这一句我不懂""ESM.jar": java.lang.NoClassDefFoundError: esm/GetESMHome"

问题解决了，哈哈，搞了三天，到今天发现完全是JB的错，看来JBX的错误还真不少
