--------------------编程问答-------------------- 环境是:IBM Rational Software Architect for WebSphere --------------------编程问答-------------------- runtime classpath有没有加入WAS runtime库? --------------------编程问答-------------------- 具体一些....刚学....
那些jar文件 --------------------编程问答-------------------- http://www-01.ibm.com/support/docview.wss?rs=2042&context=SSRTLW&dc=DB560&dc=DB520&uid=swg21358301&loc=en_US&cs=UTF-8&lang=en&rss=ct2042rational
看一下这个网址，或许对你有用 --------------------编程问答-------------------- WAS 7.0的话，至少需要加

<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer7.0/runtimes/com.ibm.ws.orb_7.0.0.jar"/>
<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer7.0/runtimes/com.ibm.ws.ejb.thinclient_7.0.0.jar"/>

WAS 6.1的话，至少需要加
<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer/runtimes/com.ibm.ws.webservices.thinclient_6.1.0.jar"/>
<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer/runtimes/com.ibm.ws.admin.client_6.1.0.jar"/>
<classpathentry kind="lib" path="D:/IBM/WebSphere/AppServer/lib/rsahelpers.jar"/>
<classpathentry kind="lib" path="D:/IBM/WebSphere/AppServer/lib/rsadbutils.jar"/>
<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer/plugins/com.ibm.ws.runtime_6.1.0.jar"/>
<classpathentry kind="lib" path="X:/IBM/WebSphere/AppServer/plugins/com.ibm.ws.emf_2.1.0.jar"/>
--------------------编程问答-------------------- 我在测试ejb时碰到同样的问题，在WebSphere\AppServer\runtimes下导入com.ibm.ws.ejb.thinclient_7.0.0.jar包就OK了。 --------------------编程问答--------------------
