我们的项目在所有数据库连接中都使用SSL，我们已成功使用this guide to SSL and JDBC thin driver为基于Java的批处理系统完成此操作。我们现在的任务是配置我们在Websphere中运行的webapp，以使用这些SSL连接到数据库。
在按照步骤instructions layed out in this blog post进行操作后，我们在运行测试连接时遇到错误（为jvm设置了-Djavax.net.debug=all）：

这表明潜在的错误是 RSA premaster secret error ，我在Google搜索并搜索了该错误;不幸的是，迄今为止没有结果有所帮助。
我在做什么似乎有什么问题？有没有人有解决这个错误或进一步了解它的根本原因的建议？
答案 0 :(得分：1)
我有一个类似的问题和“RSA premaster secret error”最近只是试图连接到SQL服务器db。似乎sunjce_provider.jar文件不在我的类路径中。
> ~/source/java/MC604_tester$ echo $JAVA_HOME # given $JAVA_HOME is set...
/usr/lib/jvm/java-7-openjdk-amd64/
> find $JAVA_HOME -iname "*sunjce*jar" # find sunjce
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/ext/sunjce_provider.jar
java -Djava.ext.dirs=lib:$JAVA_HOME/jre/lib/ext -jar build/MyAppJar.jar
我希望这会有所帮助。
