问题
项目中引用了CXF3.0.1，在JBoss EAP 6.2上部署后，出现报错：
java.lang.NoSuchMethodException: org.objectweb.asm.MethodWriter.visitLabel(org.objectweb.asm.Label)
原因
项目中的CXF相关JAR和JBoss中的Webservices模块的JAR冲突导致。
解决方法
在WEB-INF目录下创建jboss-deployment-structure.xml文件，不加载JBoss的webservices子系统。
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<ear-subdeployments-isolated>false</ear-subdeployments-isolated>
<deployment>
<exclude-subsystems>
<subsystem name="webservices" />
</exclude-subsystems>
<dependencies>
<module name="com.oracle">
<imports>
<include path="META-INF**" />
<include path="org**" />
</imports>
</module>
</dependencies>
<resources>
</resources>
</deployment>
</jboss-deployment-structure>
