你好我的新安装的tomcat 7有问题，当我尝试启动它时它没有启动并在tomcat7-stderr.log上记录错误，但有以下异常：

我试图寻找这个异常，但我想知道它是什么，我试图重新安装tomcat但它仍然给我同样的错误。 那我该怎么做才能启动我的tomcat？

UPDATE 我在Windows 7 32位机器上使用jdk 1.7

如果您使用的是OpenJDK 1.6，请尝试更改为Oracle的JDK。 这可以解决您的问题。

答案 1 :(得分：0)

java.security.NoSuchAlgorithmException：SHA1PRNG SecureRandom不可用

可以通过在Java的安全文件夹下添加正确的策略和安全文件来解决此问题
