Watch your spelling.

     public static HashMap<String, HashMap> data = new

c.setCdescription(db.rs.getString("cde=

                 data.put("sys", c);

i [sic] get alwys this error: cannot find symbol at this line

Copy and paste error messages for Usenet posts; don't paraphrase.

data.put("sys", c);

Whats wrong ?

Many things are wrong, but in particular for the error about which you
ask, 'data' is defined as a
'HashMap<String, HashMap> ' (which lacks complete generic
typification), but you are calling put with a
'( String, JConfigEntry )' argument pair. There is not a definition
for the symbol 'put( String, JConfigEntry )' so the compiler complains
that it cannot find that symbol.
