Explain the annotation used in a ______ListMaintenance.java

Question

HI,
Can anyone explain me the annotation used in a ______ListMaintenance.java(CurrencyListMaintenance.java) what does each attributes map in CCB and DB.
Like the one marked in bold
@EntityListPageMaintenance
( service* = CILTCURP, modules={foundation}, entity = currency, program* = CIPTCURP,
body = @DataElement (contents = { @FieldGroup ( *_name_* = SRCH-CRITERIA,
contents = { @DataField (name = CURRENCY_CD)})
, @ListField (name = CURRENCY_CD)}),
lists = { @List (name = CURRENCY_CD, size = 50, program = CIPTCURL, *_constantName_* = CI-CONST-CT-MAX-COMM-LIST-COLL,
baseCobolGroupName* = TCURL,
body = @DataElement (contents = { @RowField (includeRCopybook = false, entity = currency, baseCobolGroupName = TCURT)}),
headerFields* = { "CURRENCY_CD"
, "LAST_CURRENCY_CD"})})
-- I want to write a ListMaintenance.java what are the mandatory attributes in the annotation.
-- Steps required to write a ListMaintenance.java
-- Where can we find the document for annotation?

The problem is that ther eare no definite tests for character encoding. A particular byte stream can be valid in any number of different encodings (even if the resulting characters are not correct). If the characters don't happen to include any above unicode 127 then a UTF-8 stream is identical to the same characters in any number of different encodings.
It's not just a matter of there being no code for it in the library, it's impossible to do with any certainty, and to do it even probabalistically you'd have to run the results through a multi-lingual spelling checker.
If you just ask java.io to open a Reader without specifying an encoding it will assume the default encoding of your system.
