How to run jar file on shell script in linux terminal?

I made a java project.
The project is....output log message and system.out.println message. just simple.
So I changed into a jar file(the name is LinuxSample.jar).
and I wrote a shell script to run this jar file.
Look at this shell script. (speakee is package name and PrintLinux is main class name)
#!bin/bash
CLASSPATH=/home/tangooc/TANGOOC/test/libs/*
CLASSPATH="${CLASSPATH};/home/tangooc/TANGOOC/test/linux/LinuxSample.jar"
java speakee.PrintLinux
this jar file and this shell script work in Window.
but linux didn't work. I don't know why
this is error message.
Could not find or load main class

Hi Best way to run a java application is to set CLASS_PATH and PATH variable first. If your current jar file depends on external jar files you will face lots of problem. Better set your path variable like below and run the application:-
#!/usr/bin/ksh
export PATH=/usr/java/bin:$PATH
# =/usr/java/bin is your java bin folder
#set environment variable CP with all the jar libraries
CP=/home/flussi/xmlEncoder/encoder.jar
CP=${CP}:/other/jar/somejar.jar
java -Xmx256M -classpath "$CP" "com.myproj.Example"

I made it
I changed the shell script.
CLASSPATH=/home/tangooc/TANGOOC/test/client/LinuxSample.jar
LIB_TOTAL=/home/tangooc/TANGOOC/test/libs/*
echo ${LIB_TOTAL}
echo ${CLASSPATH}
java -cp ${LIB_TOTAL}:${CLASSPATH} speakee.PrintLinux
also there is another way.
CLASSPATH=/home/tangooc/TANGOOC/test/client/LinuxSample.jar
CLASSPATH=${CLASSPATH}:/home/tangooc/TANGOOC/test/libs/*
echo ${CLASSPATH}
java -cp ${CLASSPATH} speakee.PrintLinux
If the someone like me change the shell script.
and check a line, a line, a line...

Error while executing java program with .sh file

I have error while executing java command with .sh file with external library.
I have wrote a script called executer.cmd which contains
java -cp .;hsql.jar hsqlconnector %*
its working fine with windows.
For Unix also I have wrote a script and make u+x with chmod but still m getting error
of
bash: hsql.jar command not found
My executor.sh looks like
java -cp .;hsql.jar hsqlconnector %*

On Linux you must use : (colon) instead of ; (semi-colon) to separate entries on a path, because ; has a different meaning in the shell on Linux.

Mac launcher script for Java app

I need to launch a Jar file with a portable JRE. It works on Windows thanks to launch4j, it works on Ubuntu thanks to me, but not on Mac ..... and I can't test it.
The path tree of application:
abcmap/
launcher.command
bin/
abcmap.jar
jre/
bin/
java
Thinking it's like Unix system, I tried this (without specify bash):
./bin/jre/bin/java -Xms512m -Xmx1024m -jar ./bin/abcmap.jar
But this error appear:
MacBook-Pro:~ frcstnt$ /Applications/abcmap-mac/abcmap.command;
exit;
/Applications/abcmap-mac/abcmap.command: line 1:
bin/jre/bin/java: No such file or directory
logout
All files are rwx for all,
All files are UTF8 without BOM
I tried to change end of line to Unix and to "Old Mac" with Notepad++,
Archives are available on my website:
http://abc-map.fr/download/
https://translate.google.fr/translate?hl=fr&sl=fr&tl=en&u=http%3A%2F%2Fabc-map.fr%2F
Someone can help me please?
Edit: I think my problem is in the launcher, maybe encoding or bad command ?
Edit: Thanks to the Wim's answer it works. This is the script:
#!/bin/bash
SCRIPTDIR=$(dirname $0)
cd $SCRIPTDIR
${SCRIPTDIR}/bin/jre/bin/java -jar ${SCRIPTDIR}/bin/abcmap.jar

The path ./bin/jre/bin/java will be resolved relative to the current directory, not relative to the location of the command file. Try what happens if you run the command from the directory where the command is located.

I think I've found thanks to Wim Deblauwe. I use this:
#!/bin/bash
SCRIPTDIR=$(dirname $0)
cd $SCRIPTDIR
${SCRIPTDIR}/bin/jre/bin/java -jar ${SCRIPTDIR}/bin/abcmap.jar
Find the script dir, go to this dir and start operations.

It seems like you maybe don't even have the Java Runtime Evironment installed. You should try running java -version or at least java -h or java --help.
If you output is something like the following:
java: command not found
You should download and install the latest JRE and try again.
If, however, you see your java version, try first using cd to go to the directory of your jarfile and then use:
java -jar -otheroptionshere jarfile.jar
I hope this helps! Tell me, if you still got issues.

Run Jar related .Java from cmd

I am trying to do "javac Classname.java" from cmd prompt, and this Classname.java requires Jfreechart libraries/jars, and runs fine if compiled from Eclipse (because project package has jars imported).
But I want to run the file from cmd prompt and its not able to show me the output. It comes with errors like: ("package doesn't exist"), how to fix it? I need the class file and also run JNI commands to create header file.

You need to set the classpath.
You can do this in 2 ways. Either use the -classpath or -cp option:
javac -cp jar1.jar;path/to/jar2.jar Classname.java
Or, if you need it to persist, use the CLASSPATH environmental variable:
set CLASSPATH=path1;path2
javac Classname.java

If you have already managed to run your code in Eclipse, then Eclipse can help you.
In the "Debug" view, you should have something like this remaining after you have run your code:
If you right-click the bottom "terminated" text and select "Properties", you will get something like this:
You can copy the command line content and use that to run your app from the command line, or use it to set the classpath as the other answers have advised.

You just need to add the directory paths and/or .jar libraries to your "-classpath" command-line argument.
Depending on how many libraries you've got, you might well wind up with a .sh script (Linux) or .cmd file (windows) that looks something like this:
http://ubuntuforums.org/showthread.php?t=230258
java -cp jts.jar:jcommon-1.0.0.jar:jfreechart-1.0.0.jar:jhall.jar:other.jar:rss.jar -Xmx256M jclient.LoginFrame .
If you're on Windows, you'd use ";" as a separator (instead of *nix ":").

executing java using php help

so I have the following script
$execStr = 'cd /D Z:\\folder'
exec($execStr);
$execStr = 'java -jar somejar.jar';
exec($execStr);
the jar does some operations on a mysql database...
but when I run it, it appears that the jar did not run properly because the database was unchanged
but then when I run the exact same strings from the command line it would work properly
what am I doing wrong?

shell_exec('/path/to/java -jar Z:\folder\somejar.jar');
where you sub /path/to to the real place your java is run from.

Try this:
$execStr = 'java -jar Z:\folder\somejar.jar';
shell_exec($execStr);

Try running dir or ls after your cd to make sure the exec environment is persisting from one command to the next.

I guess that's because when you call java -jar ... you're no longer in Z:\folder directory. Try a single command:
java -jar "Z:\folder\somejar.jar"
