How to set the classpath to the current directory and also run the jar file named load.jar present in the current directory by providing the argument as load=2 from a linux command line.
I did try to run the jar as follows but its executing classes from some other directory.
java -cp ./load.jar:$CLASSPATH load.Start load=2

Running a from class inside your JAR file load.jar is possible via
java -jar load.jar
When doing so, you have to define the application entry point. Usually this is done by providing a manifest file that contains the Main-Class tag. For documentation and examples have a look at this page.
The argument load=2 can be supplied like in a normal Java applications:
java -jar load.jar load=2
Having also the current directory contained in the classpath, required to also make use of the Class-Path tag. See here for more information.
For example to execute from terminal (Ubuntu Linux) or even (Windows console) a java file called filex.jar use this command:
java -jar filex.jar
The file will execute in terminal.
Under linux there's a package called binfmt-support that allows you to run directly your jar without typing java -jar:
sudo apt-get install binfmt-support
chmod u+x my-jar.jar
./my-jar.jar # there you go!
For OpenSuse Linux, One can simply install the java-binfmt package in the zypper repository as shown below:
sudo zypper in java-binfmt-misc
chmod 755 file.jar
./file.jar
sudo -sH
java -jar filename.jar
Keep in mind to never run executable file in as root.
copy your file in linux Java directory
cp yourfile.jar /java/bin
open the directory
cd /java/bin
and execute your file
./java -jar yourfile.jar
or all in one try this command:
/java/bin/java -jar jarfilefolder/jarfile.jar
