您的tomcat安全配置存在问题。
检查$ {catalina.home} /conf/catalina.policy
中是否存在以下行：

  grant {

 //预编译的JSP需要访问这个包。 
 permission java.lang.RuntimePermissionaccessClassInPackage.sun.misc; 
 permission java.lang.RuntimePermissionaccessClassInPackage.sun.misc。*; 
}; 
 

并添加到$ {catalina.home} /conf/policy.d/03.catalina.policy

  //授予你jar的权限（ir.omicc ??）
授予codeBasefile：/ path /to/the/ir.omicc.utilBox/your.jar{
 permission java.security.AllPermission; 
}; 
 

这是一种解决方法，但它不安全。

So my hosting company changed their service to tomcat 7 with security manager, and from that time on I am getting this exception every time my application tries to connect to MySQL database with Hibernate. I don't know what to do, they ask me for my Tomcat permissions, but I have not defined anything special.

Can any one help me?

There's a problem in your tomcat security configuration. Check if exists in ${catalina.home}/conf/catalina.policy the following lines :

grant {

    // Precompiled JSPs need access to this package.
    permission java.lang.RuntimePermission "accessClassInPackage.sun.misc";
    permission java.lang.RuntimePermission "accessClassInPackage.sun.misc.*";
};

and add in ${catalina.home}/conf/policy.d/03.catalina.policy

// The permissions granted to your jar (ir.omicc ??)
grant codeBase "file:/path/to/the/ir.omicc.utilBox/your.jar" {
  permission java.security.AllPermission;
};

it's a workaround but it's not secure.
