Setting the java.library.path using a BAT file on windows 7

I am trying to set the java.library.path to the current directory using a BAT-file.

Heres what I use:

java -Djava.library.path=%cd%
pause

However it does not work. The command promt just returns this:

C:\Users\Johan-bar\Desktop\Arbete>java -Djava.library.path=C:\Users\Johan-bar\De
sktop\Arbete
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A ; separated list of directories, JAR archives,
                  and ZIP archives to search for class files.
    -D<name>=<value>
                  set a system property
    -verbose[:class|gc|jni]
                  enable verbose output
    -version      print product version and exit
    -version:<value>
                  require the specified version to run
    -showversion  print product version and continue
    -jre-restrict-search | -jre-no-restrict-search
                  include/exclude user private JREs in the version search
    -? -help      print this help message
    -X            print help on non-standard options
    -ea[:<packagename>...|:<classname>]
    -enableassertions[:<packagename>...|:<classname>]
                  enable assertions
    -da[:<packagename>...|:<classname>]
    -disableassertions[:<packagename>...|:<classname>]
                  disable assertions
    -esa | -enablesystemassertions
                  enable system assertions
    -dsa | -disablesystemassertions
                  disable system assertions
    -agentlib:<libname>[=<options>]
                  load native agent library <libname>, e.g. -agentlib:hprof
                    see also, -agentlib:jdwp=help and -agentlib:hprof=help
    -agentpath:<pathname>[=<options>]
                  load native agent library by full pathname
    -javaagent:<jarpath>[=<options>]
                  load Java programming language agent, see java.lang.instrument

    -splash:<imagepath>
                  show splash screen with specified image

C:\Users\Johan-bar\Desktop\Arbete>pause

What have I done wrong?

Your command is not well-formed, as stated by the error-message. Since you are trying to run a jar-file, you should specify it like this:

java [-options] -jar jarfile [args...]

In your case that would be:

java -Djava.library.path=%cd% -jar myJar

Note: The reference to the jar should contain the extension as well. If your jar is actually called myJar, consider changing it to have the .jar extension. If not, add .jar to above mentioned command.

You have probably forgotten the quotes "

Try this:

java "-Djava.library.path=C:\Users\Johan-bar\Desktop\Arbete"
