我正在研究一个小型的POC
MyValue
哪些工具
Serializable
当我试图提交交易时
ClassNotFoundException
作为根(堆栈跟踪在末尾)。
当我敲打
由于我在
atomikos tutorial
Atomikos的jar和EHCache jar都在%TOMCAT_HOME%\lib下。
当Atomikos事务管理器在Tomcat中全局安装时,现在还必须在相同的全局位置安装JDBC驱动程序(即:安装到Tomcat_HOME/lib文件夹中)。如果不这样做,则在web应用程序部署期间将出现NoClassDefFoundErrors或ClassNotFoundException,甚至classcasteexception。
这不是Atomikos和Tomcat的限制,而是Tomcat和Atomikos必须遵循的J2EE类加载设计的限制。
我是不是看错了指令了?
有人遇到过这个问题吗?

maxElementsInMemory="1000"
