Re: How to extract information from packed fields from AS400 in java!

Azeem, the real problem here seems to me to be the person that decided to 
join several different fields into one long field and then pack it.  How 
on earth can you be expected to find the border lines for fields in a 
string of undescribed numbers? 

A short conversation with the person that designed such a thing seems in 
order.  Wear heavy boots.

Then you have to do it the hard way.  Get the data as a byte array and
parse out the fields.  The Toolbox still may help.  It has converters for
various types of AS/400 numeric and text data.  Once you determine which
bytes of a byte array make up a field, you could use a Toolbox converter 
to
convert it from a byte array to a Java object.  One more thing that may
help is the Toolbox RecordFormat class.  This class lets you describe the
format of a byte array of data.  As you extract data via the class it is
converted from AS/400 format to Java format.  For an example see the Data
Queue Consumer example in the sequential data queue section of the Toolbox
programmer's guide.

No!
it is a packed field which has the data corresponding to more than 1
entity. eg. like the details of the employee are stored in a single packed
field and i have to extract the employee no,employee name.....etc.
Thnx & Regards

Are you talking about a packed decimal number?  The Toolbox for Java has a
class that converts between Java numeric types and AS/400 packed decimal
numbers.

Hi!
