tJavaRow List to String conversion

Hi,
I have a tJavaRow with the line of code below:
myarray = ((java.util.List<String>)globalMap.get("input_row.ReturnValue")).toArray();
But I get the error:
Type mismatch: cannot convert from Object[] to String[]
input_row.ReturnValue is type List and myarray is initialised as type array. What would be the correct syntaxt to return myarray as an array?

Your help much appreciated.
Thanks.

Re: tJavaRow List to String conversion

Add "new String" as a parameter to the toArray() method. This block of code demonstrates
		String[] sodas = null;

List<String> sodaList = new ArrayList<String>();

sodaList.add("coke");
sodaList.add("pepsi");
sodaList.add("7-up");

sodas = sodaList.toArray(new String);
for( String s : sodas ) {
System.out.println(s);
}

Thanks for your help.
I pasted in the code you sent after trying to modify mine to work but to no avail.
I get the error: ArrayList cannot be resolved to a type. Can you assist?

String[] sodas = null;

List<String> sodaList = new ArrayList<String>();

sodaList.add("coke");
sodaList.add("pepsi");

sodas = sodaList.toArray(new String);

Re: tJavaRow List to String conversion

You'll need to import java.util.List and java.util.ArrayList. In the tJavaRow Advanced Settings, add the following to the code editor
import java.util.List;
import java.util.ArrayList;
