运行部署的htmlunit程序报错

 

开发完成的程序在eclipse中运行完好，这两天打包运行接连出现问题。
每一步都需要求助搜索引擎，百度、google真是太伟大了。

问题1:运行报错java.lang.NoClassDefFoundError: javax/activation/DataSource
在eclipse中并为主动引入该包，运行正常，发现已经包含在plugins下的javaee.jar中。
 java发送邮件必备的jar包(mail.jar和activation.jar)

问题2：2010-08-27 13:36:41,604 [main] INFO  - I/O exception (javax.net.ssl.SSLKeyExcep
ion) caught when processing request: RSA premaster secret error
2010-08-27 13:36:41,604 [main] INFO  - Retrying request

原因：运行在JDK1.5下，默认应该有该类，但却找不到。classpath中手工引入jre目录下jce.jar
和sunjce_provider.jar才运行成功。
