General :: How To Place The Java Location In My $PATH
Sep 22, 2010
I have a program that has a GUI which I have placed in /usr/local/bin however when I invoke the program I receive the following error:
Unable to find a supported JDK or JRE version. Version 1.3.1 or higher is required. Check your installation and use +javahome to specify the JDK or JRE location
I have since installed Java into the usr/local/ directory however I am now just totally Lost! Additionally, I believe that i have tried to install Java several times with no luck.
Questions:
1) Where should java be installed to have system wide access to all programs?
2) How can I place the Java location in my $PATH? here I am going to need very easy and detailed instructions?
3) Is there a way to ensure that the location where I intall java gets updates?
Java applet not loading image with relative path(e.g. images/1.jpg) but loads image with absolute path(i.e. from /root/user/images/1.jpg) . This is a problem when i want to host the applet on web server
I have downloaded java and installed it with chmod +x and then ./bin package.
Hereunder is an output from CLI (putty)
I understand that the system knows the java is in a wrong place but if I do java -version it finds it correctly. I don't know and I don't understand how do I need to tell the OS that the java is somewhere else, I just did that with export java home and java path but still dosen't work, it keep tells when I do whereis java "java: /usr/share/java"
Select a starter package from the table at the top of this page and download it to your development computer. To install the SDK, simply unpack the starter package to a safe location and then add the location to your PATH.How do I add a location to PATH?
I installed Ubuntu 10.04 only be dismayed to find ${HOME}/bin FIRST IN THE PATH. I blogged about it at my blog (I sudo an xterm rather than just sudoing to get a different background for the sudo'd xterm): [url]
I agree that some new user should probably not be logging on as root. But if the replacement for 'ls' is in their ${HOME}/bin/ the sudo'd shell inherits the same PATH, umask, and everything else! In general I take a dim view of a sudo only way of doing things. It seems to cause more problems than it solves for disciplined, knowledgeable users. In the case of Ubuntu it caused me to create a /root folder for root to reset the umask back from 077 which is what I use over to 022 which is what root should use. The /root/.profile of course made sure there is no /home/me/bin in the sudo'd PATH. It didn't matter because somebody is not just SETTING the file perms and is instead calculating them based off of modifications to the umask. JUST SET THEM! I ran into a problem with GRUB getting things fouled up because I was having to remove the new kernels and instead of using the command line option (much prefereable) used Synaptic Manager instead: [url]
In fhe case of an infection living in a user's file space you really should want to go in to clean it out as some other user than the user that is infected. Having said that the hackers seem to be going for the whole enchilada right off the bat. A WARNING is in order here. DO NOT USE A ROOT ACCOUNT OR SUDO FOR NORMAL TASKS! But please put ${HOME}/bin last in the PATH or preferably don't even put it in the PATH at all. Let users add it themselves if they want it. Also once hackers figure out that hijacking a sudo tty (from what I just read else-where here I would say several hackers are working on doing that right now - sendmail my ****) is a dandy way of doing things you really will need to provide for ways of cleaning a user infestation out by going at it some other way than through that infected user. A lot of Ubuntu users have only one login account, the one they created when they set the machine up.
I have added the smbd file location to the path of root. I can now execute it from any location. I noticed after reboot of the machine (RHEL 5) that this file location is no longer in the path. How do I make this permanent?
I have openSUSE 11.3 Gnome installed. The nautilus address bar shows the "Button Bar" and if I press Ctrl+L it swaps to the "Text Location Bar". The Text Location bar is where you see the full path to the directory that you're viewing.But I can't set the default addressing to the Text Location Bar.What else should I do to get the text location bar (i.e. the full path) to be the default view in the address bar?
I have installed CentOS 5.5 and included the java development package. When I typed java -version, I got java 1.6.0. The problem is with the javac command, which is not found. I tried the following:
I'm fighting my way through JAVA. But have hit another wall. Basically I need to to set paths in java so it can set/read files/director for Linux,Mac and windows.
The tutorials I'm using says to do this through the FileSystems class eg
Code:
However this reports it is missing, so a look on line says I need the headers so I set them with
Code:
This gives the following error
This has me totally confused as the tutorial shows this and checking online shows this, do I need to link in libraries or something like that?

I'm setting up a RHEL 4 VM and have installed Oracle Java 1.6 from a bin file to /opt. I've added it into the PATH but when I try to run a installer that needs Java to run it says that it can't find a Java installation in my PATH but when I execute a which java I get the following:
I am trying to set my java path so that it is in effect for all users including the root user. I set the path correctly in /etc/profile and that works for my personal user, but when i try to run the same commands using sudo, i get messages saying that it can't find the java path.
I want to ask how i set Linux class path for mail.jar and mysql-connector.jar. I have set the class path for java with the command.
Code:
when i do java -version it's work fine.
Also if i want to know that what shell i am using how can i find it.Also what is the command for showing class path variables or how can i see my JAVA_HOME class path.Means after setting the class path for above two files how can i see that these files have added.
When i write echo $CLASSPATH or echo $JAVA_HOME it shows nothing no error but again shows the prompt.
One thing more i want to run a java program on Linux it is in a package (named asteriskproject). It consist of 10 java files. I have run this program on windows using netbeans IDE.For this program i need to set my Linux class path for the above mentioned files, and this is my first time that i am running any program on Linux. So i want to ask how can i run my program. Simply put this asteriskproject directory in any folder and run the main file using javac. Is it right way to run the program that consist of package ?
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?
Experimenting with shell variables, accidentally deleted the path variable how could I return to the original path value. What kinds of problems will I have if I don't have a path variable.
I have a path c:windowsackup I need this string to be changed into /windows/back/up I used the command -bash-3.00$ echo windackup | sed 's/\//g' but the output is windbackup
prefix=user@my-server: find . -depth -type d -name .git -printf '%h�' | while read -d "" path ; do ( cd "$path" || exit $?
[code]....
How shall i go about changing the absolute path to relative path, so that /home/git/mirror/android/adb/ndk.git gets converted to /mirror/android/adb/ndk.git //echo <command> "$prefix$PWD.git" ?? - anything for relative path?
