Question

I can’t run this regular expression on Java:

 String regex = "/^{m:\"(.*)\",s:([0-9]{1,15}),r:([0-9]{1,15}),t:([0-9]{1,2})}$/";

String data = "{m:\"texttexttext\",s:1231,r:23123,t:1}";
Pattern p = Pattern.compile(regex_Write_clientToServer);

Matcher a = p.matcher(data);

This the same regex and the same data on regex site’s tester ( as http://gskinner.com/RegExr/ ) works fine!

Two problems:

1. In java, (unlike perl etc) regexes are not wrapped in / characters
2. You must escape your { literals:

Try this:

String regex = "^\\{m:\"(.*)\",s:([0-9]{1,15}),r:([0-9]{1,15}),t:([0-9]{1,2})\\}$";
