| is a regex metacharacter and it needs to be escaped, try "\\|"

Java's split uses a regex, so you need to double escape pipe:

String[] getVal=value.split("\\|");

If it were a plain regex you'd need to escape it anyway, but in java "\" is a special character in a string, due to characters like \t and \n, hence the double escape.
