passing arguments from shell to java

Hi:

I have a script called runjava:

Code:
The content ---
search=$1
dpi=$2
prefix=$3
input=$4
output=$5

java  -Djava.library.path=./lib/path/Lib -classpath .:lib/path/Lib/mylib.jar myclass $search $dpi $prefix $input $output


How does myclass parse arguments ---
String searchTerm = (args[0]).trim();
String dpiStr = (args[1]).trim();
int dpi = Integer.parseInt(dpiStr);
String prefix = (args[2]).trim();
String inputFile = (args[3]).trim();
String outputPath = (args[4]).trim();


How to run --- 
./runjava $search $dpi $prefix $input $output


Problem ---
My java class cannot receive the arguments passed by shell script.

I think I understand the issue here.

e.g.
./runjava "Search something here" "150" "page" input/input.pdf output

arg1 = Search
arg2 = something
arg3 = ....

I am a newbie and not sure how to make arg1 = "Search something here"

Try quoting the variables you pass to the java command.

Code:
java  -Djava.library.path=./lib/path/Lib -classpath .:lib/path/Lib/mylib.jar myclass "$search" "$dpi" "$prefix" "$input" "$output"
