写了一个关于加解密的java类，使用java本身自带main方法运行完全正常，但是当我在jsp引用该java类时却出现如下问题：苦苦思索，还是无法解决，请各位帮帮忙！！
使用环境：jb7+weblogic6+sqlserver2000

参考：
1)下载jce1_2_2.zip,解压四个文件；
2)将以上四个文件添加到jb中tools的configure server中的class，重启jb即可。
you try

谢谢楼上各位，现附源代码：谢谢各位指点！
1）testdes.java

package testtestprj;

/*
安全程序 DESede/DES测试
*/
import java.security.*;
import javax.crypto.*;
public class testdes {
public static void main(String[] args){
testdes my=new testdes();
my.run();
}
public void run() {
//添加新安全算法,如果用JCE就要把它添加进去
Security.addProvider(new com.sun.crypto.provider.SunJCE());
String Algorithm="DES"; //定义加密算法,可用 DES,DESede,Blowfish
String myinfo="要加密的信息";
try {
//生成密钥
KeyGenerator keygen = KeyGenerator.getInstance(Algorithm);
SecretKey deskey = keygen.generateKey();

//加密
System.out.println("加密前的二进串:"+byte2hex(myinfo.getBytes()));
System.out.println("加密前的信息:"+myinfo);
Cipher c1 = Cipher.getInstance(Algorithm);
c1.init(Cipher.ENCRYPT_MODE,deskey);
byte[] cipherByte=c1.doFinal(myinfo.getBytes());
System.out.println("加密后的二进串:"+byte2hex(cipherByte));
//解密
c1 = Cipher.getInstance(Algorithm);
c1.init(Cipher.DECRYPT_MODE,deskey);
byte[] clearByte=c1.doFinal(cipherByte);
System.out.println("解密后的二进串:"+byte2hex(clearByte));
System.out.println("解密后的信息:"+(new String(clearByte)));

}
catch (java.security.NoSuchAlgorithmException e1) {e1.printStackTrace();}
catch (javax.crypto.NoSuchPaddingException e2) {e2.printStackTrace();}
catch (java.lang.Exception e3) {e3.printStackTrace();}
}
public String byte2hex(byte[] b) //二行制转字符串
{
String hs="";
String stmp="";
for (int n=0;n<b.length;n++)
{
stmp=(java.lang.Integer.toHexString(b[n] & 0XFF));
if (stmp.length()==1) hs=hs+"0"+stmp;
else hs=hs+stmp;
if (n<b.length-1) hs=hs+":";
}
return hs.toUpperCase();
}

}
2)test.jsp
<%@ page contentType="text/html; charset=GBK" %>
<html>
<head>
<title>
test
</title>
</head>
<jsp:useBean id="testBeanId" scope="session" class="testtestprj.testBean" />
<jsp:setProperty name="testBeanId" property="*" />
<body>
<h1>

<form method="post">

</body>
</html>
