looking for any alternatives
httpinput----jcn----httpreply
| Code: |
MbElement outContent1 = outPart1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Content-Type", "application/zip; name=httpfile.zip");
MbElement outContent2 = outPart1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Content-Transfer-Encoding", "binary");
MbElement outContent3 = outPart1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Content-Disposition", "form-data; name="+'"'+"httpfile.zip"+'"'+"; filename="+'"'+"httpfile.zip"+'"');
MbElement outContent4 = outPart1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Name", "file.zip");
MbElement outData1 = outPart1.createElementAsLastChild(MbElement.TYPE_NAME, "Data", null);
MbElement outBlob1 = outData1.createElementAsLastChild(MbBLOB.PARSER_NAME);
outBlob1.setName("BLOB");
MbElement outBlob1a = outBlob1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "BLOB", bitstream); |

Why are you telling us this? What response did you expect to get?

It's difficult to advise you when we don't know exactly what you are trying to do. Please explain in more detail what you need to do, what you tried, and what happened. |

As @timber said, so do we.
You said you "tried something like this" and posted some code. If it was "something like that", how about posting the exact code?
You say you got an htm file instead of the attachment you were expecting - what's in the htm file? What's the attachment you expect? It looks like some kind of zip file - zipped from where? how?
What does the user trace say the message tree looks like after it leaves the JCN?
Better information, better advice.

MbElement outHttpHeader = outRoot.createElementAsLastChild("HTTPReplyHeader");
outHttpHeader.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Content-Disposition", "attachment; filename="+NewString);
outHttpHeader.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "Content-Type", "application/zip"); |
