How to run multiple JAR files at differnt locations from a command prompt

Question

I have 2 jar files at different locations. I need to run both these jar files from a single command prompt window.

I referred to many SO links and google links and created this batch job.

START SET JPOS_DIR=D:\Installable\JPOS\Iso8583jPOSJavaAgent-0.0.11
cd /D %JPOS_DIR%
"C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

START SET JPOS_DIR=D:\Installable\JPOS_Instance-2\Iso8583jPOSJavaAgent-0.0.11
cd /D %JPOS_DIR%
start "C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

But i am getting the below error message

"Windows cannot find -cp. make sure you type the name correctly and try again."

Can someone tell me what I am missing here ?

Answer 1

The syntax for the start command is as follows,

START "title" [/D path] [options] "command" [parameters]

so in the command,

start "C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

it considers "C:\\Program Files\\Java\\jdk1.7.0_75\\bin\\java" as title and -cp as the command to run, thats why you get the error.

Try using the following command,

start "title" "C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

Alternatively, you can run without any quotes where we don't need to pass the title,

start java -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

set Java in PATH before executing this command. Hope this helps.

Answer 2

-cp is not valid windows cdm command... I think you missed start at first execution:

"C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain

must be

start "C:\Program Files\Java\jdk1.7.0_75\bin\java" -cp Iso8583jPOSJavaAgent-0.0.11.jar com.hp.sv.iso8583.jpos.ISOForwarderMain
