Re: How to input and display Chinese characters to and from MySQL if I use Ruby on Rails [by Herong]

Forum:: How to input and display Chinese characters to and from MySQL if I use Ruby on Rails
I know little about Ruby on Rails at this moment, but I am sure it supports UTF-8 encoding. To input and display Chinese characters, all you need to do is to put content="text/html; charset=utf-8" in your Web pages, and follow these suggestions when communicating with MySQL:

* Define all text columns as UTF-8.
* Run "SET character_set_client=utf8" and "SET character_set_connection=utf8".
* Include all text data in UTF-8 encoding in SQL statements.
* Run "SET character_set_result=utf8".
* Fetch all text data in UTF-8 encoding.

Apache: Certificate Verification: Error (20): unable to get local issuer certificate [by wolfbuda]

Forum:: Apache: Certificate Verification: Error (20): unable to get local issuer certificate
I there,

I'm in trouble to validate client certificate on apache. If I verify it by hand
it report ok: openssl verify -CAfile root.crt -untrusted all.crt
client.pem
But if a copy root.crt and all.crt to /etc/httpd/conf/ssl.crt/ run
c_rehash /etc/httpd/conf/ssl.crt/ and restart httpd it can't validate
the client certificate.
Please help!

Re: bitwise snippet in DES algorithm [by Herong]

Forum:: bitwise snippet in DES algorithm
Here is a quick explanation of the setBit() method:

   private static void setBit(byte[] data, int pos, int val) {
      int posByte = pos/8; 
      int posBit = pos%8;
      byte oldByte = data[posByte];
      oldByte = (byte) (((0xFF7F>>posBit) & oldByte) & 0x00FF);
      byte newByte = (byte) ((val<<(8-(posBit+1))) | oldByte);
      data[posByte] = newByte;
   }

int posByte = pos/8; - Calculates the position index of the byte to be modified in the data[] array.

int posBit = pos%8; - Calculates the position index of the bit to be modified within the byte to be modified.

byte oldByte = data[posByte]; - Puts old value of the byte to "oldByte".

0xFF7F - Represents "11111111 01111111".

(0xFF7F>>posBit) - Shifts the '0' to the position of the bit to be modified.

((0xFF7F>>posBit) & oldByte - Sets the bit to be modified to '0', and keeps other bits unchanged.

oldByte = (byte) (((0xFF7F>>posBit) & oldByte) & 0x00FF); - Saves back the modified byte value back to "oldByte".

val<<(8-(posBit+1)) - Shifts the new value to the bit to be modified.

byte newByte = (byte) ((val<<(8-(posBit+1))) | oldByte); - Combines the new value on the bit to be modified with old values on other bits, and saves the entire byte value to "newByte".

data[posByte] = newByte; - Stores the final byte value back to the byte array.

hi all
i need help to create a tree structure on jsp whose node have data from data structure its like

C1.0
C1.1

where all B,B1.0,B1.1,C,C1.0,C1.1 all are information from the database.
when i click on B it will show me B1.0,B1.1 and when i click on C it will show C1.0,C1.1

Thanx
