Hi,
Thanks for your reply .. the code I am using is working fine if I execute it as a standalone program .. but I am using the code in a signed applet which is integrated in a web application ... I am getting the exception when accessed from multiple webclients...  

FYI. I am using dcm4che 1.4.9

Seems you are using an old version of the DICOM Tools? We are using the
dcm4che2 libs since some time and have done a lot of changes and new
features.
The code for exporting has although changed a bit:

DicomExporter exporter = new DicomExporter();
File dcmFile = new File("/home/hermenj/jhermen.dcm");
ImagePlus ip = new ImagePlus("/home/hermenj/img.jpg");

DicomObject dObj = exporter.createHeader(ip, true, true, true);

// if wanted, set additional tags...
DicomAnonymizer.addTag(dObj, Tag.PatientName, "Testpatient");

exporter.writeImage(dObj, ip, dcmFile);

Please try the latest version from
http://santec.tudor.lu/project/optimage/dicom/start and be sure to exchange
all dcm4che libs with the ones from the new dicom-tools.

Greets
