Thanks santhanu.

But that article deals with binary file path.

But my flat PDF file is placed in server location ("../test11.pdf").

I tried below java code. This helps me to down load the file from server location. But i am not able to attach that to work object.

if you have any java code to attach the document from server path it will be helpful.

/*The File Path along with the name to download need to be mentioned here */

String filePath = tools.getParamValue("FilePath");

java.io.FileInputStream fileInputStream=null;

java.io.File file = new java.io.File(filePath);

byte[] bFile = new byte[(int) file.length()];

try {

                     fileInputStream = new java.io.FileInputStream(file);

                     fileInputStream.read(bFile);

                     fileInputStream.close();

}

catch(Exception e){

e.printStackTrace();

}

/* Change the name of the Test.docx to the actual file name that needs to be downloaded with extension.*/

String sErrorMessage = tools.sendFile(bFile, "Test.docx", false, null, true);

if (sErrorMessage != null){                                                         

                 tools.getThread().getThreadPage().putString("pyXMLStream", sErrorMessage);

}
