Changing the ProfileImagePath value in the registry
ProfileImagePath registry value
The ProfileList registry key contains some sub-keys, which are nothing but the list of User Account Security Identifiers (SID). Each of the SID represents an Account. The key is located here:

How to change JBoss default port

1. Open the JBoss Folder

2. Goto its Deploy folder.

3. Goto the jbossweb-tomcat55.sar

4. Find out the server.xml inside that folder. Actually this is the server configure file of the BuildIn Tomcat.

5. Find the folowing Tag

<Connector port="8080" address="${jboss.bind.address}"…….

6. Change the port number here.

7. Restart the server.

Jboss預設只能以127.0.0.1本機存取，如要改變binding address，啟動時指令如下：

run -c default -Djboss.bind.address=0.0.0.0

用run -h可查看help

Install PAE enabled kernel in 32 bit Ubuntu to use 4GB RAM

$ sudo apt-get update

$ sudo reboot

修改Oracle Express的HTTP port

Oracle database express edition default http port是8080,容易與其他的web server衝到，以下指令可將其改為8087

C:\>sqlplus /nolog

SQL> connect
Enter user-name: system
Enter password: <輸入密碼>
Connected.
SQL> Exec DBMS_XDB.SETHTTPPORT(8087);

PL/SQL procedure successfully completed.

SQL>quit
Disconnected from Oracle Database 10g Express Edition Release 10.2.0.1.0 – Production

修改後立即生效。

使用JCIFS存取samba folder

JCIFS web site: http://jcifs.samba.org/

Sample code:

jcifs.Config.setProperty("jcifs.smb.client.domain", "APNET");
jcifs.Config.setProperty("jcifs.smb.client.username", "apuser");
jcifs.Config.setProperty("jcifs.smb.client.password", "appassword");
java.io.FileInputStream input = new java.io.FileInputStream("d:/temp/test.txt");
jcifs.smb.SmbFileOutputStream output = new jcifs.smb.SmbFileOutputStream(
        "smb://hostname/upload$/test.txt");
byte[] b = new byte[8192];
int n;
while ((n = input.read(b)) > 0) {
    System.out.write(b, 0, n);
    output.write(b, 0, n);
}
input.close();
output.close();

用 Spring 取得 Oracle Sequence 及 Hibernate 的設定

Oracle:
create sequence ORDER_SEQ
start with 1 
increment by 1 
nomaxvalue;

Spring:
使用Spring提供的org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer:
OracleSequenceMaxValueIncrementer incr = new OracleSequenceMaxValueIncrementer(dataSource, "ORDER_SEQ");
int seq = incr.nextIntValue();

Hibernate:
<id name="id" column="ID" type="java.lang.Long">
    <generator class="sequence">
        <param name="sequence">ORDER_SEQ</param>
    </generator>
</id>

Find which process has occupied which port

In Linux:
lsof – list open files
The syntax for using "lsof" is:
lsof -i tcp:3480
or
lsof -i udp:3480
if you are interested in port 3480, over the appropriate protocol, TCP or UDP...

In Windows:

C:\>netstat -abno

使用中連線

  協定   本機位址               外部位址               狀態            PID
  TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       1932
 [httpd.exe]
  TCP    0.0.0.0:113            0.0.0.0:0              LISTENING       3580
 [ident.exe]
  TCP    0.0.0.0:135            0.0.0.0:0              LISTENING       800
  RpcSs
 [svchost.exe]
  TCP    0.0.0.0:1025           0.0.0.0:0              LISTENING       472
 [wininit.exe]

In AIX:

netstat -Aa | gret 8080
rmsock xxxxxxxx tcpcb
ps -ef|grep thepid

Tomcat 5.5 SSL Configuration

Create a certificate keystore by executing the following command:
keytool -genkey -alias tomcat -keyalg RSA
and specify a password value of "changeit".

Uncomment the "SSL HTTP/1.1 Connector" entry in $CATALINA_HOME/conf/server.xml and tweak as necessary.

Add keystorePass element if you used a different keystore (and Certificate) password than the one Tomcat expects (changeit).

Delete the certificate keystore:
keytool -delete -alias tomcat

Change the password from “changeit” to “newpass”:
keytool -keypasswd -alias tomcat -keypass changeit -new newpass

The keystore is by default stored in a file named .keystore in the user's home directory, as determined by the "user.home" system property.

Read http://java.sun.com/j2se/1.3/docs/tooldocs/win32/keytool.html for more information about keytool.

How do I change the IP address on Oracle 10g

If the server's IP address changed, these are the first things I would look at:

The TNSNAMES.ORA file on the client -- does it have the IP address hardcoded? If so, change it. Does it use the machine name? If so, does the machine name resolve to the correct IP address on your client machine?

The LISTENER.ORA file on the server -- does it explicitly specify the old IP address as its listening address?

用java壓縮tar檔

package mytest;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.tools.tar.TarEntry;
import org.apache.tools.tar.TarOutputStream;

public class AntTarTest {

public static void main(String[] args) throws Exception {
String[] inputFiles = new String[] { "D:/txt/network.txt",
"D:/txt/sql.txt" };
new AntTarTest().tar("d:/AntTarTest.tar", inputFiles);
}

public void tar(String tarFileName, String[] inputFiles) throws IOException {
TarOutputStream out = new TarOutputStream(new FileOutputStream(
tarFileName));
int buffersize = 1024;
byte[] buf = new byte[buffersize];
for (int i = 0; i < inputFiles.length; i++) {
File file = new File(inputFiles[i]);
TarEntry te = new TarEntry(file.getName());
te.setSize(file.length());
out.putNextEntry(te);
FileInputStream in = new FileInputStream(file);
int count;
while ((count = in.read(buf, 0, buffersize)) != -1)
out.write(buf, 0, count);
out.closeEntry();
in.close();
}
out.close();
System.out.println("compress ok.");
}

}
