How to upload RTC attachments to a Work Item? Need WorkItemUploadAttachmentModification example please.


SImon Starkie (115) | asked May 30 '15, 1:22 p.m.
We are trying to develop an RTC API for uploading attachments to a Work Item.
We are following the example at https://rsjazz.wordpress.com/2013/07/12/work-item-command-line-client-to-add-a-comment/

But the sample code has compile errors for the "WorkItemUploadAttachmentModification" statements:
WorkItemUploadAttachmentModification operation = new WorkItemUploadAttachmentModification("TestAttachment.txt",IContent.CONTENT_TYPE_TEXT,IContent.ENCODING_UTF_8operation.run(workItem, null);

WorkItemUploadAttachmentModification operation1 = new WorkItemUploadAttachmentModification("Test.pdf",IContent.CONTENT_TYPE_UNKNOWN,IContent.ENCODING_UTF_8operation1.run(workItem, null);

The compile errors are:
Description Resource Path Location Type
ENCODING_UTF_8operation cannot be resolved or is not a field ModifyWorkItemUploadAttachmentOperation.java /EISRTCUtility/src/com/ibm/js/team/workitem/plainjava/example line 149 Java Problem

Description Resource Path Location Type
ENCODING_UTF_8operation1 cannot be resolved or is not a field ModifyWorkItemUploadAttachmentOperation.java /EISRTCUtility/src/com/ibm/js/team/workitem/plainjava/example line 150 Java Problem

Does anyone have a working example of "WorkItemUploadAttachmentModification"?

Thanks.

This line of code in the sample was wrong: 
WorkItemUploadAttachmentModification operation = new WorkItemUploadAttachmentModification("TestAttachment.txt",IContent.CONTENT_TYPE_TEXT,IContent.ENCODING_UTF_8operation.run(workItem, null);

We replaced it with these two lines of code:
WorkItemUploadAttachmentModification operation = new WorkItemUploadAttachmentModification("TestAttachment.txt",IContent.CONTENT_TYPE_TEXT,IContent.ENCODING_UTF_8);
operation.run(workItem, null);

The following is the full code and is working for us:
