Hi Guys,

I need to send some parametes to along with a file to the server side code.(servlet) . I have gone through follwoing link from this forum but still not able to get the required results.

http://www.mqseries.net/phpBB2/viewtopic.php?t=38268&postdays=0&postorder=asc&highlight=mime+esql&start=30

My Problem is : servlet not able to get the field values and file sent from Message Broker. Servlet can understand that the incomming message is a MIME message . It can detect the field values if passes as a URL.

I am using following ESQL code:

------Start of ESQL----

SET OutputRoot.HTTPRequestHeader.POST = '/examples/servlets/servlet/DefaultFileItemHari?';
SET OutputRoot.HTTPRequestHeader."Content-Type" = 'multipart/form-data; boundary=' || boundary;
SET OutputLocalEnvironment.Destination.HTTP.RequestURL = 'http://localhost:8080/examples/servlets/servlet/DefaultFileItemHari';
-- SET OutputLocalEnvironment.Destination.HTTP.RequestURL ='http://localhost:8080/examples/servlets/servlet/DefaultFileItemHari?firstname=Pankaj&lastname=Shahane';

SET OutputRoot.HTTPRequestHeader.Host = 'localhost';

SET OutputRoot.Properties.ContentType = 'multipart/form-data; boundary=' || boundary;

--CREATE FIELD OutputRoot.MIME.Parts;
CREATE LASTCHILD OF OutputRoot DOMAIN('MIME') NAME('Parts');
CREATE LASTCHILD OF OutputRoot.MIME.Parts TYPE Name NAME 'Part';
-- SET OutputRoot.MIME."Parts"."Part"[1]."Content-Disposition" = 'form-data';
DECLARE P1 REFERENCE TO OutputRoot.MIME.Parts.Part[1];
-- SET P1."Content-Type" = 'text/plain';
SET P1."Content-Disposition" = 'form-data';
SET P1."name" = 'firstname';
CREATE LASTCHILD OF P1 TYPE Name NAME 'Data';
CREATE LASTCHILD OF P1.Data DOMAIN('BLOB') value(abc);

CREATE LASTCHILD OF OutputRoot.MIME.Parts TYPE Name NAME 'Part';
DECLARE P2 REFERENCE TO OutputRoot.MIME.Parts.Part[2];
SET P2."Content-Type" = 'text/plain';
SET P2."Content-Disposition" = 'form-data';
SET P2."name" = 'lastname';
CREATE LASTCHILD OF P2 TYPE Name NAME 'Data';
CREATE LASTCHILD OF P2.Data DOMAIN('BLOB') PARSE(blastname);

-- Note blastname is a blob variable..

DECLARE part1Data BLOB ASBITSTREAM(InputRoot.XMLNSC, InputProperties.Encoding, InputProperties.CodedCharSetId);
CREATE LASTCHILD OF OutputRoot.MIME.Parts TYPE Name NAME 'Part';
DECLARE P3 REFERENCE TO OutputRoot.MIME.Parts.Part[3];
SET P3."Content-Type" = 'text/xml';
SET P3."Content-Disposition" = 'form-data';
--SET P3."Content-Disposition" ='application/x-www-form-urlencoded';
SET P3."name" = 'uploadMe';
SET P3."filename"='HelpMe.txt';
CREATE LASTCHILD OF P3 TYPE Name NAME 'Data';
CREATE LASTCHILD OF P3.Data DOMAIN('BLOB') PARSE(part1Data);

-----End of ESQL

Serverside code excerpt : System.out.println("Code is working");

-- Java code starts -------------------

String firstName = request.getParameter("firstname");
String lastName = request.getParameter("lastname");
System.out.println("First Name is :"+firstName+" and Last Name : "+lastName);

if (firstName != null || lastName != null) {

out.println("First Name:"+firstName+" Last Name:"+lastName);

} else {
out.println(rb.getString("requestparams.no-params"));
}

try {
formItems = upload.parseRequest(request, 5000, 5000, "C:\\Pankaj\\dummy.txt");
System.out.println("formItems object....."+formItems.toString());
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Iterator iterator = formItems.iterator();
System.out.println("Iterator ............"+iterator.toString());
while (iterator.hasNext()) {

FileItem item = (FileItem) iterator.next();

if (item.isFormField()) { //this is a parameter passed on the request
String parmName = item.getFieldName(); //this is your meta data
String parmVal = item.getString();
System.out.println("Param Name :"+parmName+" and param Value : "+parmVal);
}
else { java.io.InputStream uploadedStream = item.getInputStream(); //get the content

System.out.println("UploadStream...."+uploadedStream.toString());
object is populated here.
along with meta data.
}
}
System.out.println("Iterator DO NOT HAVE VALUE.");

Java code Result

Code is working

Guys desparately need help on this ..
