I am working for making Attachment with SOAP (we are making a SOAP Messages with Attachment and then sent via socket It�s not any web service). It�s very simple application

The below jar files are in my class path
saaj-ri.jar, saaj-api.jar, dom4j.jar,activation.jar,mail.jar,comman-logging.jar

My code is:
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage _msg = mf.createMessage();
SOAPPart spart = _msg.getSOAPPart();
SOAPEnvelope senv = spart.getEnvelope();
SOAPBody soapbody = senv.getBody();
SOAPHeader sheaser = senv.getHeader();
FileDataSource fdsource = new FileDataSource(new File("C:/n.xml"));
DataHandler dhandler = new DataHandler(fdsource);
AttachmentPart apart = _msg.createAttachmentPart(dhandler);

I got below error

java.lang.NoClassDefFoundError at com.sun.xml.messaging.saaj.soap.MessageImpl.createAttachmentPart(
at javax.xml.soap.SOAPMessage.createAttachmentPart(Unknown Source)

You may be experiencing a mailcap issue � though I can't be certain.
When trying to find a DataContentHandler (DCH) JAF 1.0.2 checks for mailcap files in the following order
  • user.home/mailcap
  • java.home/lib/mailcap
  • META-INF/mailcap
  • META-INF/mailcap.default

  • Issues:
  • Some SAAJ implementations provide their own mailcap file. In that case it is necessary to make sure that the mail.jar (with its META-INF/mailcap file) occurs after the SAAJ implementation jar (which may have it's own META-INF/mailcap) in the class path. So move that mail.jar to the end of the classpath.
  • The user.home/mailcap or java.home/lib/mailcap may specify a DataContentHandler that is incompatible with the SAAJ-implementation and/or that is provided in a JAR not currently in your class path.
