JAVA classpath pass file as command line argument

Question

I have a program which is located in

say

$A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch

$A430CLASS is the path where my class file is present.

i want to run it through shell script so i entered following command :

java -classpath $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties

$A430CONF is the path where the batch.properties file is present. GlobalReportBatch is my class file name As you can see i want to pass this batch.properties file as argument to my java program. but when i run my script it tries to replace "." in batch.props file to "/" it gives me NoClassDefFound error.

what if, java -classpath . $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties — Hovercraft Full Of Eels

Hovercraft is right : "$A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch" is interpreted as the classpath and that's while the last argument is interpreted as the class. — Denys Séguret

What you put after the -classpath option must be a list of directories and JAR files, separated by : (on Unix-like operating systems) or ; (on Windows).

Look at what you are passing:

-classpath $A430CLASS/com.airbus.adcsip.batch.GlobalReportBatch

Remove the slash / between $A430CLASS and your class name; replace it by a space:

-classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch

So the entire line becomes:

java -classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties

actually $A430CLASS and com....GlobalReportBatch is related.. consider $A430CLASS as my home directory... so is your syntax right?

@Datta: again you've not told us your package structure yet.

my class file is in $A430CLASS/com/airbus/adcsip/batch/ where my class GlobalReportBatch is located... $A430CLASS - is my variable set to some xyz path so it becomes xyz path/com/airbus/.....

@Datta: but again, please tell us what is the package structure? I'm not sure how to ask this any clearer sort of way. What is on the package statement at the top of your java file?

@DattaprasadPatil Try @Jesper answer: java -classpath $A430CLASS com.airbus.adcsip.batch.GlobalReportBatch $A430CONF/batch.properties It should work.
