jboss7下 Cipher 报异常JCE cannot authenticate the provider BC的解决方法

1、代码中引用了bcprov-jdk16-146.jar，在部署到jboss7.1.1时报如下异常：
Caused by: java.lang.SecurityException: JCE cannot authenticate the provider BC
at javax.crypto.SunJCE_b.a(DashoA13*..)
at javax.crypto.SecretKeyFactory.getInstance(DashoA13*..)
at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:667)
... 95 more
Caused by: java.util.jar.JarException: Cannot parse jar:file:/Users/himajumdar/Work/jboss/jboss-5.1.0.GA/server/default/tmp/a00c-b5p2h4-hgi84jo1-1-hgi84qe5-w/csa.ear!/lib/bcprov-jdk16-146
at javax.crypto.SunJCE_c.a(DashoA13*..)
at javax.crypto.SunJCE_b.b(DashoA13*..)
at javax.crypto.SunJCE_b.a(DashoA13*..)
... 98 more

2、然后按照网上说的在JAVA_HOME/jre/lib/security/java.security下增加
security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider to java.security
将该jar包放到JAVA_HOME/jre/lib/ext下，并将项目中的该jar去掉

结果又报出如下问题：
ERROR java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider
at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190)
at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:468)
at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:456)
at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:423)

解决方法如下：

1、 在jboss下创建如下目录：$JBOSS_HOME/modules/org/bouncycastle/main，将bcprov-jdk16-146.jar、module.xml(该文件可去其它同级目录copy过来)放到该目录下，
module.xml文件放如下 内容：

<module xmlns="urn:jboss:module:1.1" name="org.bouncycastle">
    <resources>
        <resource-root path="bcprov-jdk16-146.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api" slot="main" export="true"/>
    </dependencies>
</module>

2、在 $JBOSS_HOME/standalone/configuration/standalone.xm文件中，找到这一行，将它替换为：

<subsystem xmlns="urn:jboss:domain:ee:1.0"/>

并将之替换为下面所描述的内容：

 <subsystem xmlns="urn:jboss:domain:ee:1.0">
    <global-modules>
        <module name="org.bouncycastle" slot="main"/>
    </global-modules>
</subsystem>
