axis 动态发布报错 The arguments do not match the signature 而后卡死

最近公司用到webservice简单学习了一下axis的动态发布就直接用上了，运行过程中经常出现如下错误，过后webservice无法访问，只有重启tomcat。

测试发现如果axis采用动态发布（即用jws的方式）用jmeter加压到并发为20，重启tomcat，系统立即卡死，不断报错。

解决的方法是采用静态方式发布：即在WEB-INF中添加server-config.wsdd,内容如下：

<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>    
   <service name="myService" provider="java:RPC">
        <parameter name="className" value="com.casit.Test"/>
        <parameter name="allowedMethods" value="test"/>
    </service> 
<transport name="http">
<requestFlow>
    <handler type="URLMapper"/>
</requestFlow>
</transport>
</deployment>

修改红色部分一看就明白哈，我不多说

而后通过地址：http://localhost:9090/axis/services/myService访问这个webservice
