我有一个Java Web应用程序的工作,我需要生成一个MAC使用3DES算法。 代码工作没有问题在Weblogic 10.3,但是当我试图运行在不同的WebLogic应用程序的问题就来了,类似的版本(10.3.1)。
这是我的代码:
public String getMac(String inkey, String data) throws Exception {
byte[] out = new byte[8];
try {
// if I commend this line, the result is the same
Security.addProvider(new BouncyCastleProvider());
// this loop proves the BC provider is there
for (Provider p : Security.getProviders()) {
log.debug("--");
log.debug(p.getName());
log.debug(p.getInfo());
}
try {
BouncyCastleProvider bc = new BouncyCastleProvider();
// class is there, no problem
log.debug("info" + bc.getInfo());
DES9797Alg3 alg3 = new DES9797Alg3();
// class is there, no problem
log.debug("alg3" + alg3.toString());
} catch (Exception e) {
log.error("error BouncyCastleProvider classes");
}
log.debug("length: " + inkey.length());
if (inkey.length() < 48)
inkey += inkey.substring(0, 16);
byte[] rawkey = hexStringToByteArray(inkey);
DESedeKeySpec keyspec = new DESedeKeySpec(rawkey);
SecretKeyFactory keyfactory = SecretKeyFactory.getInstance("DESede");
SecretKey key = keyfactory.generateSecret(keyspec);
Mac mac = Mac.getInstance("ISO9797Alg3Mac");
mac.init(key);
mac.update(data.getBytes());
mac.doFinal(out, 0);
} catch (Exception e) {
log.error("Error generating MAC X9_19", e);
throw new Exception("Error generating MAC X9_19", e);
}
这是我的错误:

我不明白,为什么错误说org.bouncycastle.jce.provider.JCEMac$DES9797Alg3
是不存在的。 这可能是“java.security”期待在另一个地方? 我已经要求服务器管理员到库中赞同目录复制,但不是我不知道,如果这是去工作和生活方式发生这种情况。
请注意,即使我删除“Security.addProvider(新BouncyCastleProvider());” 线,在现有供应商的名单,BC上市。

BC是存在的,而且,同一版本里面我我的战争文件了。
我用Google搜索多小时,没有运气,希望有人能为我指向正确的方向。
