Problem in pattern matching special characters
 

Hi,
I need to match the following characters in a pattern ` < > { } ; "
|
I tried to do it through this method : Pattern.compile(pattern1 |
pattern2);
Like this:
Pattern pacxFTPF11 = Pattern.compile("`|<|>|{|}|;|\"|\\|");
Matcher macxFTPF11 = pacxFTPF11.matcher(acxFTPFile);

But it is throwing exceptions:

Exception in thread "main" java.util.regex.PatternSyntaxException:
Illegal repet
ition near index 5
`|<|>|{|}|;|"|\|
^

Try this: (you have to escape { and }

Pattern pacxFTPF11 = Pattern.compile("`|<|>|\\{|\\}|;|\"|\\|");
