After more
testing using the post method I have discovered that the problem is in the value I am tring to return:
This will not work even though it is what I need.
String jReturnValues = "{eFlag:'NoError'}";
arg1.getWriter().write(jReturnValues);
This does work but I need several values sent.
String jReturnValues = "NoError";
arg1.getWriter().write(jReturnValues);
