使用SSL访问Web服务时出错

Question

我有一个程序应该将文件发送到Web服务,这需要SSL连接.我按如下方式运行程序:

SET JAVA_HOME=C:\Program Files\Java\jre1.6.0_07
SET com.ibm.SSL.ConfigURL=ssl.client.props
"%JAVA_HOME%\bin\java" -cp ".;Test.jar" ca.mypackage.Main

这工作正常,但当我改变第一行

SET JAVA_HOME=C:\Program Files\IBM\SDP\runtimes\base_v7\java\jre

我收到以下错误:

所以看起来这个问题与我正在使用的JRE有关,但似乎没有意义的是非IBM JRE工作正常,但IBM JRE没有.有什么想法或建议吗？

Answer 1

尝试在设置代码中的某处添加这两行:

Security.setProperty("ssl.SocketFactory.provider", "com.ibm.jsse2.SSLSocketFactoryImpl");
Security.setProperty("ssl.ServerSocketFactory.provider", "com.ibm.jsse2.SSLServerSocketFactoryImpl");

Java仅允许JVM的一个SSL连接工厂类.如果您正在使用WebSphere Application Server v6x/7x/8x附带的JDK或Rational Application Developer中的任何其他WebSphere服务器工具,那么那些需要来自WebSphere Application的IBM(com.ibm.websphere.ssl.protocol.SSLSocketFactory)特定类服务器运行时 因为java安全文件的JSSE套接字工厂设置如下

# Default JSSE socket factories
#ssl.SocketFactory.provider=com.ibm.jsse2.SSLSocketFactoryImpl
#ssl.ServerSocketFactory.provider=com.ibm.jsse2.SSLServerSocketFactoryImpl

# WebSphere socket factories (in cryptosf.jar)
ssl.SocketFactory.provider=com.ibm.websphere.ssl.protocol.SSLSocketFactory
ssl.ServerSocketFactory.provider=com.ibm.websphere.ssl.protocol.SSLServerSocketFactory

因此,如果取消注释Default JSSE Socket工厂并注释掉WebSphere的工厂,那么WAS就会呕吐.

更好的解决方法是在类路径中包含com.ibm.ws.security.crypto.jar文件.此jar文件依赖于com.ibm.ffdc.jar文件,因此您需要在类路径中很好地使用它.这两个jarfiles都可以在下面找到<WebSphere_Install_Dirctory>/plugins/

如果您的非 IBM jre 是 sun，那么它已经附带了与其一起打包的 SSL 类实现。

IBM jre 似乎根本不包含 SSL 实现类。
