Windows/Linux -classpath flag seperator is different

When I am using the -classpath command line option the syntax is different on Windows vs Linux, this is a headache, anyone know why or a way around it?:
Windows:
javac -classpath "xxxx.jar;yyyy.jar" *.java
Linux:
javac -classpath "xxxx.jar:yyyy.jar" *.java
I have verified that if tried the other way around it fails...
Thanks.

Hi!
This problem results from the different ways Linux and Windows manage path entries. The solution to this is to read the system properties (System.getProperty("file.pathseparator"). I'm not sure if this is the correct identifier. Just display all properties and you'll get it.

Micro SD crashes entire OS(Mac) but works perfectly on Windows/Linux

Hello,
I bought a Micro SD(class 10) card and an adapter that works perfectly(and extremely fast) on Windows/Linux but it doesn't matter the file system scheme that I use with, my Mac will ENTIRELY FREEZE while trying to read/write anything!.
Tried different adapters and different filesystems(fat32, exfat, ntfs, HFS in all flavors, etc).
Thanks in advance!

Ok, no problem with the backup thing.
But the apps? Will I have to reinstall them all?
I´ve tryied deleteng the preferences file and restarting, but nothing happens. When I try to manually add an interface on the network preferences, there is no ethernet choice. In terminal, there is no ethernet interface when I call ifconfig, and I cannot ping to another computer.
I´m verifying/repairing disk permissions right now.

Zip/unzip API for both Windows/Linux

hello, there:
I wonder if it's possible that we can create a zip/unzip class that can package the files in Windows and unzip them in Linux?
Fact is, that I created a Swing application, which shows a tree of a certain folder. Upon request, the app also zip that folder(including it's subs) and upload it to a remote database as a SQL blob. Well, I want this app to work on both Windows/Linux, meaning when it runs on Linux, it should be able to download the package and unzip the package to its full extend.
But it looks like that the files zipped in one OS can't be easily unzipped to its original in another. Is it doable or not possible due to the very different nature of the file systems of different platform?
I used a open source code from this link, http://www.wakhok.ac.jp/~tatsuo/sen97/10shuu/UnZip.java.html
Will the zip package from jdk help (java.util.zip)? I haven't tried that one yet.
Thanks,
Sway

You don't have to use special libraries as the tools you need are all in the java.util package.
There is however an Apache Commons library for this though which you can find here
http://commons.apache.org/sandbox/compress/
Note that zip = archiving and compression where as gz or gzip on Linux is only compression and you would use tar to do the archiving (tar.gz), that's why there are two separate compression classes in the Java API.

DB2 Migration from Windows - Linux supported with Backup/Restore ?

Hi folks,
we have to do a DB2 V9.1 migration from Windows -> Linux. Both servers are Intel based. Is it official supported by SAP to do this without SAP migration tools? E.g. with a backup/restore or redirected restore? I heard about it, but i'm not sure.
Thanks a lot
Jochen
Edited by: Jochen Raab on Mar 1, 2010 5:40 PM

Hi Jochen,
Please have a look at the DB2 docu.
http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/topic/com.ibm.db2.luw.admin.ha.doc/doc/c0005960.html
It clearly stats that Linux and Windows are not compatible.
DB2® database systems support some backup and restore operations between different operating systems and hardware platforms.
The supported platforms for DB2 backup and restore operations can be grouped into one of three families:
Big-endian Linux® and UNIX®
Little-endian Linux and UNIX
Windows®
A database backup from one platform family can only be restored on any system within the same platform family. For Windows operating systems, you can restore a database created on DB2 Universal Database (UDB) V8 on a DB2 Version 9 database system. For Linux and UNIX operating systems, as long as the endianness (big endian or little endian) of the backup and restore platforms is the same, you can restore backups that were produced on DB2 UDB V8 on DB2 Version 9.
So you need to do an eport/import.
Regards,
Joachim

Windows主机访问虚拟机linux中的oracle实例的安装方法

在学习oracle时一般都会在windows中安装虚拟机,在虚拟机安装linux系统并[安装oracle.
下面是自己的在windows中安装虚拟机并让windows主机能访问虚拟机中oracle实例的安装方法写的不好请大家多多包涵.
一.准备安装所需要的软件：
1.VMware虚拟机的下载和安装在我的博客中已经提到，这里就不再详细阐述。
2.先推荐一个redhat的下载地址，RedHat Linux 5企业版：content.gougou.com/content，
这个比较全面，但是也比较大（2.68G），如果自己有合适的linux安装版本，可以不使用这个。
二.在VMware虚拟机为RedHat Linux创建新的虚拟机就不详述了
三.在新建的虚拟机里安装RedHat Linux就不详述了
四.在linux系统中安装oracle
为了创建一个新的oracle用户输入和以下相似的命令:
# /usr/sbin/useradd -g oinstall -G dba[,oper] oracle
给oralce用户设置密码
# passwd oracle
修改内核参数编辑/etc/sysctl.conf文件
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
当在/etc/sysctl.conf文件中指定这些内核参数后你要重启系统
也可以执行以下命令让内核参数生效
/sbin/sysctl -p
给oracle用户设置shell限制
为了提高数据库软件在linux系统中的性能你必须给oracle用户增加以下shell限制:
shell limit item in limits.confg hard limit
能打开文件的最大数量 nofile 65536
单个用户可用的最大进程数 nproc 16384
在/etc/security/limits.conf文件中增加以下限制:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
在/ect/pam.d/login文件如果下面显示的参数没有就增加到该文件中
session required pam_limits.so
根据oracle用户的默认shell,对默认的shell启动文件进行以下更改:
对于Bourne, Bash, or Korn shell在/etc/profile文件中增加下面的代码
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
对C shell(csh or tcsh)在/etc/csh.login文件中增加以下代码
if ( $USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
endif
创建oracle根目录可以输入以下相似的命令:
# mkdir -p /mount_point/app/oracle_sw_owner
# chown -R oracle:oinstall /mount_point/app/oracle_sw_owner
# chmod -R 775 /mount_point/app/oracle_sw_owner
如果oracle根目录的加载点是/u01并且oracle软件使用者用户为oracle那么oracle根目录的路径为:
/u01/app/oracle
[root@weblogic28 ~]# mkdir -p /u01/app/oracle
[root@weblogic28 ~]# chown -R oracle:oinstall /u01/app/oracle
[root@weblogic28 ~]# chmod -R 775 /u01/app/oracle
当你配置oracle用户环境变量时设置ORACLE_BASE时就将oracle根目录的路径赋给ORACLE_BASE
创建存储数据库文件和数据库恢复文件的目录
创建存储数据库文件的目录的命令如下:
# mkdir /mount_point/oradata
# chown oracle:oinstall /mount_point/oradata
# chmod 775 /mount_point/oradata
将存放数据库文件的目录创建在oracle根目录下/u01/app/oracle/oradata
[root@weblogic28 ~]# mkdir /u01/app/oracle/oradata
[root@weblogic28 ~]# chown oracle:oinstall /u01/app/oracle/oradata
[root@weblogic28 ~]# chmod 775 /u01/app/oracle/oradata
创建oracle Home目录/u01/app/oracle/10.2.0/db
[root@weblogic28 ~]# mkdir /u01/app/oracle/10.2.0/db
[root@weblogic28 ~]# chown oracle:oinstall /u01/app/oracle/10.2.0/db
[root@weblogic28 ~]# chmod 775 /u01/app/oracle/10.2.0/db
创建存储数据库恢复文件的目录的命令如下:
# mkdir /mount_point/flash_recovery_area
# chown oracle:oinstall /mount_point/flash_recovery_area
# chmod 775 /mount_point/flash_recovery_area
将存放数据库恢复文件的目录创建在oracle根目录下/u01/app/oracle
[root@weblogic28 ~]# mkdir /u01/app/oracle/flash_recovery_area
[root@weblogic28 ~]# chown oracle:oinstall /u01/app/oracle/flash_recovery_area
[root@weblogic28 ~]# chmod 775 /u01/app/oracle/flash_recovery_area
创建一个/tmp目录
[root@weblogic28 ~]# mkdir /u01/tmp
[root@weblogic28 ~]# chmod a+wr /u01/tmp
切换到oracle用户来设置环境变量
[oracle@weblogic28 ~]$

如果是远程安装可以使用VNC远程连接到linux服务器上来执行界面安装
1、配置并开启vnc服务
[oracle@localhost ~]$ vncserver
You will require a password to access your desktops.
Password: ---这里要求输入vnc客户端登录的密码并重复
Verify:
New 'localhost.localdomain:2 (oracle)' desktop is localhost.localdomain:2
Creating default startup script. /home/oracle/.vnc/xstartup
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:2.log
----如上告诉你vnc终端已经创建好，用的是第二个终端
2、在创建vnc服务的用户目录下会生成一个.vnc的隐藏目录
[oracle@localhost ~]$ ls -a
. .bash_profile Disk1 .gconfd .gstreamer-0.10 .metacity README.htm .viminfo
.. .bashrc .eggcups .gnome .gtkrc-1.2-gnome2 .mozilla .redhat .vnc
.bash_history .chewing .emacs .gnome2 .ICEauthority .nautilus .scim .Xauthority
.bash_logout Desktop .gconf .gnome2_private .kde p8202632_10205_Linux-x86-64.zip .Trash .zshrc
3、进入.vnc目录，找到xstartup可执行文件，用vi 编辑器打开
[oracle@localhost ~]$ cd .vnc/
[oracle@localhost .vnc]$ ls
localhost.localdomain:2.log localhost.localdomain:2.pid passwd xstartup
[oracle@localhost .vnc]$ vi xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc ---去掉前面的#号即可 --保存退出
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
~
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
"xstartup" 12L, 333C 已写入
[oracle@localhost .vnc]$ vncserver
New 'localhost.localdomain:3 (oracle)' desktop is localhost.localdomain:3
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:3.log
4、清除刚才创建的vnc虚拟终端
[oracle@localhost .vnc]$ vncserver -kill :1
Can't find file /home/oracle/.vnc/localhost.localdomain:1.pid
You'll have to kill the Xvnc process manually
[oracle@localhost .vnc]$ vncserver -kill :2
Killing Xvnc process ID 11889
[oracle@localhost .vnc]$ vncserver -kill :3
Killing Xvnc process ID 11945
[oracle@localhost .vnc]$ vncserver -kill :4
Can't find file /home/oracle/.vnc/localhost.localdomain:4.pid
You'll have to kill the Xvnc process manually
5、重新建立新的vnc虚拟终端
[oracle@localhost .vnc]$ vncserver
New 'localhost.localdomain:2 (oracle)' desktop is localhost.localdomain:2
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:2.log --该终端号为 :2
6、在windows客户端用RealVNC软件中的Run VNC Viewer客户端连接。
7、在Run VNC Viewer 只需输入linux服务器的地址和刚才生成的终端号:2
格式：192.168.1.56:2
8、输入刚才配置vnc服务的时候配的即可登录linux服务器图形界面。
如果是本地安装的话执行下面的步骤
用root用户登录
[root@weblogic28 ~]#xhost + 让任何用户都是启用图形界面
切换到oracle用户
[root@weblogic28 ~]su - oracle
[oracle@localhost ~]$ cd /database
[oracle@weblogic28 database]$./runInstaller
设置虚拟机的IP地址让主机可以访问虚拟机
1、     NAT方式
1.1     右键单击主机任务栏上的网络连接图标，选择打开网络连接页面
1.2     启动”VMware Network Adapter VMnet8” 和 “VMware Network Adapter VMnet1”这两个连接
1.3     右键单击“本地连接”,选择属性，打开”本地连接属性”对话框，选择”高级”标签,打开高级标签页面，选中选项”允许其它网络用户通过此计算机的internet连接来连接”，然后在”家庭网络连接”下拉列表中选择VMware Network Adapter VMnet8。
1.4     在虚拟机上右键单击你要设置的虚拟机选“setting”（因为有的不止虚拟一台），打开”Hardware”标签页，单击”device”下的ethernet，此时在右边选中NAT：Used to share the host’s IP address. 然后点击确定。
1.5     打开虚拟机上的Edit菜单，选择virtual network settings打开virtual network editor页面，先打开automatic bridging标签页，关闭automagic bridging，点击应用；再打开DHCP标签页，启动DHCP服务，然后点击应用；最后打开NAT标签页，启动NAT服务，然后点击应用；点击确定后退出
1.9     启动虚拟机中的系统。
1.10     设置虚拟机中的系统的IP地址为192.168.100.200，默认网关为192.168.100.1 （VMware Network Adapter VMnet8的IP地址），DNS服务器设置和主机中的DNS服务器一致。
1.11     重新加载网络参数或者重新启动虚拟机中的系统。
1.12设置静态IP地址.
(1).命令行设置(该方式只是临时设置,系统重启后失效)
[1].设置IP和掩码
ifconfig 接口名(如eth0) IP地址 netmask 子网掩码
[2].设置网关
route add default gw 默认网关
[3].设置DNS服务器地址
echo "nameserver DNS服务器地址">/etc/resolv.conf
实例:假设设置eth0的IP:192.168.1.100,DNS:192.168.1.12
ifconfig eth0 192.168.100.200 netmask 255.255.255.0
route add default gw 192.168.100.1
echo "nameserver=192.168.1.12">/etc/resolv.conf
(2).修改文件来实现配置网络(需要重启网络接口重启后IP不会改变)
[1].修改IP地址,文件:/etc/sysconfig/network-scripts/ifcfg-接口名
这里假设网络接口名为eth0.
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 (注:这里填的是网络接口名)
BOOTPROTO=static
ONBOOT=yes (注:是否随系统启动)
IPADDR=192.168.100.200(注:这里填写的是IP地址)
PREFIX=24 (注:这里填写的是掩码的长度)
NETMASK=255.255.255.0
GATEWAY=192.168.100.1( 注:这里写的是网关)就是VMware Network Adapter VMnet8的IP地址
[2].修改DNS
echo "nameserver DNS服务器地址">/etc/resolv.conf
[3].重启网络接口(假设为eth0)
ifup eth0(注:这里写的是接口名)
关闭linux防火墙
（1）重启后永久性生效：
开启：chkconfig iptables on
关闭：chkconfig iptables off
（2）即时生效，重启后失效：
开启：service iptables start
关闭：service iptables stop
linux下Oracle自动启动与停止
1.修改Oracle系统配置文件/etc/oratab
/etc/oratab 格式为： SID:ORACLE_HOME:AUTO
把AUTO域设置为Y(大写)，只有这样，oracle 自带的dbstart和dbshut才能够发挥作用。我的为：
$ORACLE_SID:$ORACLE_HOME:Y
这儿的ORACLE_SID和ORACLE_HOME是oracle用户下的环境变量,在不同的电脑上有不同的值.当你打开/etc/oratab的时候,修改一下就行了.
2.编写服务脚本
在/etc/rc.d/init.d目录下创建oracle文件作为启动脚本,内容如下:容如下:
#!/bin/sh
#chkconfig: 2345
#description:oracle_orcl
# /etc/rc.d/init.d/oracle_orcl
# auto start database orcl instance
#set oracle env
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/oracle/product/10.2.0/db_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=orcl
ORACLE_USER=oracle
#start or stop script
case $1 in
start)
su - "$ORACLE_USER"<<EOO
lsnrctl start LISTENER
sqlplus /nolog<<EOS
connect /as sysdba
startup
EOS
EOO
stop)
su - "$ORACLE_USER"<<EOO
lsnrctl stop LISTENER
sqlplus /nolog<<EOS
connect /as sysdba
shutdown immediate
EOS
EOO
echo "Usage: $0 {start|stop}"
esac
在oracle用户下输入如上的内容,然后保存退出,由于是启动脚本,需要执行权限;执行命令chmod a+x oracle授予oracle执行权限.
3.建立服务连接
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc2.d/S99oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc3.d/S99oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc5.d/S99oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc0.d/K01oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc6.d/K01oracle
或可以通过执行以下命令来实现
chkconfig --add oracle
chkconfig命令运行成功后，在rc2.d，rc3.d，rc4.d，rc5.d下面建立了S99oracle 连接文件，可以在系统启动的时候，运行脚本启动数据库。在rc0.d、rc1.d和rc6.d目录下面建立了K99oracle文件，用于在系统关闭的时候自动运行脚本关闭数据库。可以使用 chkconfig --list oracle 命令查看服务配置，关于chkconfig更多的用法，可以通过man chkconfig查看
4.测试
启动，运行命令:./oracle_linuxdb start
关闭，执行命令:./oracle_linuxdb stop
可以用sqlplus user/passward@tnsname来测试启动和关闭数据库是否成功。现在重新启动linux主机,看数据库是否自动启动了.
这样主机就能访问虚拟机中的oracle数据库了

其实运用Oracle Virtual Box + OEL会使安装数据库变得更加简便。

Is there any iPhone simulator available on windows/Linux?

Hello,
I think this is silly to ask because iPhone OS is totally different than others.
Is there any iPhone simulator available on windows/Linux?

What hardware and OS should I prefferably choose for best possible Firefox performace? (Windows/Linux)

What is the best configuration I should choose for best performance with Firefox?
Considering OS included also, Windows/Linux,
as there might be some platform specific accelerations or drivers dependent things.

If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 8.0.x: http://www.mozilla.com/en-US/firefox/all.html
Uninstall your current Firefox version if possible.
*Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Windows can not manage to have different DPI 1080p and 4K monitor

Windows can not manage to have different DPI 1080p and 4K screen. However, it is impossible not to have a magnification of 1080p but 25-35% on Dell 4K (P2715Q) intimidate. Windows 8.1 increases on both screens. I have clicked out that it will not change
on both screens, and only on 4K Dell P2715Q.
I have Nvidia GTX 680 and latest drivers 347.88! Windows is 8.1 Pro with Mediacenter.

Hi,
Agree with you, quote from “Windows 8.1 DPI Scaling Enhancements” Windows blog.
“here have been some questions about when per-display DPI scaling is used (different DPI scaling values per display) and I wanted to add a note here to clarify. On Windows 8.1 when you have the “Let me choose one scaling level for all
my displays” check box checked (not checked by default) one uniform DPI scaling value is used for all displays.”

Simple way for run an application on a pc without OS (window,linux,...)?

i need a simple pdf for a way for run an application on a pc without OS (window,linux,...).

Take a look here, and also note the related links i the bottom http://zone.ni.com/devzone/cda/tut/p/id/2733
Then you are using Labview RT on a PC, a real time OS will be installed in the process. The OS is the PharLap, Real-Time OS . So you will indeed be using a OS
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

De Windows à Linux, maintenant ?

Bonjour,
J'aimerai me renseigner sur les possibilités, limitations de passer depuis un labview windows vers un linux (supporté bien entendu).
J'utilise à l'heure actuelle :
- du cDAQ
- du cRIO
- du FPGA (donc),
- du DMM
sous Windows.
Quels problèmes, qui est ce qui est supporté par Linux et qui ne l'est pas ? Qu'est ce que cela m'impose de faire lors du passage Windows / Linux etc.
Toute expérience est bonne à prendre. Merci !
Résolu !

I am running programs on a Windows/Linux hybrid network and have come across some newline issues. What is the best way to read a file and make sure that it conforms to the native characters? That is, how should I convert a Windows file to Linux format on Linux and vice versa?
Thank you

1) Always explicitly specify the character encoding used when writing text - I use utf-8. Don't rely on the default.
2) Always explicitly specify the EOL - I use "\n" which works with just about anything on both Linux and Windows except for Notepad.

Detect programatically if AutoVue DD is installed (Windows/Linux)

Hello,
I need help on detecting if user has AutoVue Desktop Deployment installed (on Windows/Linux OS) via Java. In Windows I thought of looking out registries under "HKEY_LOCAL_MACHINE\Software\" with no success (at least I couldn't find any registry about AutoVue). In Linux I guess I could use something like "whereis" to find autovue.exe but Windows is priority right now. Hope you guys can help me pointing some ways to solve my problem.
Thanks in advance.

Hello,
I agree with you that this may not be an AutoVue specific question, feel free to edit/delete this topic.
Anyway, based on your answer I could find a registry under this location: HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Oracle AutoVue Desktop Deployment
Thank you.

Apple should make a server hardware/OS with iOS level security. This could compete well with the breach infested pre secure OS/hardware server systems like Windows Linux OSX. It should be structurally immune to phishing etc

Apple should make a server hardware/OS with iOS level security. This could compete well with the breach infested pre secure OS/hardware server systems like Windows Linux OSX. It should be structurally immune to phishing etc and could be sold easily as a secure alternative. It should be based on structural hardware based security as has been demonstrated in the iOS operating system and the hardware should be made in secure facilities in the US. Those Chinese put weaknesses into the hardware they make as has been documented on 60 minutes.

Apple's entry in the server market has come and gone - is there a question in there somewhere?

Java - linux Classpath

Hi I am new to Linux classpath. I am using Fedora Core 5 which comes along with jdk1.4.2. I read one of the messages that are posted in another form and set the classpath in the linux in the /etc/profiles folder. The below code I added over there:
JAVA_HOME=/usr/java/jdk1.5.0_08
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/htmlconverter.jar:$JAVA_HOME/lib/jconsole.jar
export PATH CLASSPATH
Now when i run javac -version it is showing the below output.
javac 1.5.0_08
javac: no source files
But when I run java -version it is showing me the below output.
java version "1.4.2"
gij (GNU libgcj) version 4.1.1 20060525 (Red Hat 4.1.1-1)
Copyright (C) 2006 Free Software Foundation, Inc.

I don't understand what mistake I am doing. Please guide me and i would like to know how it is showing 1.5 for javac version and 1.4.2 for java version.
Thanks in advance.

This has nothing to do with the classpath and all to do with the PATH.
Somewhere, you have a 1.4.2 JRE in the PATH, before the 1.5.0 JDK and it's JRE.
So if you call javac, it will execute 1.5.0's because the 1.4.2 JRE doesn't have it, but java will be 1.4.2's because that the first one it'll find.

Windows steals boot flag in dual boot

I have installed windows on sda1, boot on sda2, mostly replicating what is suggested in the windows dual boot article. On arch setup, I flag 2 as bootable and 1 as not bootable. However, when windows runs, it flags sda1 as bootable and the next time I restart, I go immediately into windows. Is there a way to stop windows from doing this outside of windows OS?

Like jowilkin said, the bootable flag does not matter as long as Windows can boot its ok to leave it as it is.
When you are dual booting with Windows, its easier to have grub installed to the MBR so that it overwrites Windows' bootloader. Grub can boot to just about anything.

Windows/Linux -classpath flag seperator is different
