How to run a java GUI at startup in IceWM?

Question

I have been trying to run java based GUI onBoot in IceWM linux, tried to run it through different runlevels..rc3, rc4, and rc5 but couldn't run it. here what I am trying..

sudo java -jar /path/to/jar in a /etc/init.d/script and linking it like

sudo ln -s /etc/init.d/script /etc/rc3.d/S99script

I also made sure that the script has proper permissions too. Help is appreciated.

Run java app as root. Java app as root. Java based gui as root. Java gui as root through init.d. I'd better go take some sleep. — baldrs, Jan 27 '15 at 06:57
Never run java as root, and never start gui from init scripts. Start from ~/.xinitrc or ~/.xprofile — baldrs, Jan 27 '15 at 06:59
It is your X server who has them, specifically `xinit` script — baldrs, Jan 27 '15 at 07:02
@baldrs hm...I will check and try. Btw I got my solution. So upvote will be obliged. — Ahmed S. Durrani, Jan 27 '15 at 07:04

1)login with your user then use "ls -a" command.you can find .bash_profile file.
2)suppose still you dont have then create manually "vi .bash_profile" in your home directory(eg. vi /home/user/.bash_profile)
3)give 755 permission to bash_profile .(chmod 755 /home/user/.bash_profile)
4)then edit vi .bash_profile
export JAVA_HOME=(Path of ur java location- {eg. /opt/jdk1.6.0_45})
export PATH=$PATH:(Path of ur java location- {eg. /opt/jdk1.6.0_45})
PATH=$PATH:$HOME/bin

:wq (save and exit)

5)run .bash_profile (sh .bash_profile)

At last I found the solution! Apparently it was the sudo that was making problem..

So I referenced /path/to/java/binaries into /etc/sudoers/ file and started java file from /home/loggeduser/.profile (I did this because there is only one user to my system) and done..rebooted and I have the Java GUI running.

 For Linux  
  +Go to Home directory of user.(eg:- cd /home/user)
  +every user having ".bash_profile" file in home directory.(ls -a --> to check   hidden (.)file)  
  +you can give path or export java in ".bash_profile.  
  eg:- vi /home/user/.bash_profile  
  # .bash_profile  
  # Get the aliases and functions  
  if [ -f ~/.bashrc ]; then  
  . ~/.bashrc  
  fi  
  # User specific environment and startup programs  
  export JAVA_HOME=/opt/jdk1.6.0_45  
  export PATH=$PATH:/opt/jdk1.6.0_45  
  #export JBOSS_HOME=/jbossdev/brms-standalone-5.3.1/jboss-as  
  #export PATH=$PATH:/jbossdev/brms-standalone-5.3.1/jboss-as/bin  
  PATH=$PATH:$HOME/bin  
  export PATH  
  :wq!  
  +then grant 755 permission to .bash_profile file (chmod -R 755 /home/user/.bash_profile).  
  +execute sh .bash_profile.  
  so now you can run it through different runlevels..rc3, rc4, and rc5.
