求帮助 --------------------编程问答-------------------- 一般是由冲突造成的。 --------------------编程问答-------------------- http://axis.8716.n7.nabble.com/java-lang-NoSuchMethodError-org-apache-axiom-om-OMFactory-createOMElement-td47844.html --------------------编程问答-------------------- 我也知道是有冲突的，可是不知道哪里冲突了，我用的是Axis2 １.６.１
从apache网上下的jar包解压后得到axiom的三个相关jar.

axiom-dom-1.2.12.jar
axiom-impl-1.2.12.jar
axiom-api-1.2.12.jar

请问这能有什么冲突呢？
