the line above will not work. Velocity != Java, so you do not
automatically have access to Character.isDigit(char).

if i were you, i would move all of that logic into a tool class like:
public class MyCharacterTool {
public int getLetterCount(String foo) {
int letterCount = 0;
for (int i=0; i < foo.length(); i++) {
if (!Character.isDigit(foo.charAt(i))) {
letterCount++;
}
}
return letterCount;
}
}
then you add an instance of MyCharacterTool to your Velocity Context...
context.put("charTool", new MyCharacterTool());
and use it in your template like...
#set( $letterCount = $charTool.getLetterCount($stdCommListNo) )
#if( $letterCount > 0)
<do some string printing>
#else
<do some number printing>
#end
