Custom Upload, and Attachment Handler

[ryan McCullough]

I'm writing an app that needs to use java to recoeve a small upload, and attach it to several issues (upload can be duplicated if necessary). I have created a handler servlet, but I'm struggeling with finding the proper API classes that handle the attachment code.

does Jira have a temp folder thats suitable for uploading to?

where should the file end up?

which classes handle file upload?

Thanks for your help...

You probably need:

MultiPartRequestWrapper mprw = (MultiPartRequestWrapper) ServletActionContext.getMultiPartRequest();
if (mprw!=null && mprw.getFileNames().hasMoreElements())
{
  byte[] data=null;
  Enumeration<String> fileNames = mprw.getFileNames();
  if (fileNames.hasMoreElements())
  {
    while(fileNames.hasMoreElements())
    {
      String fileName = fileNames.nextElement();
      File file = mprw.getFile(fileName);		
...

2)

Try getting ComponentAccessor.getComponent(JiraHome.class);

That will give you .getDataDirectory() , which is your JIRA_HOME/data folder, allowing you to create a temp file in JIRA_HOME/tmp or your own location.

Any Ideas on how to programatically attach a File object to an issue?

points encourage additional answers :) You need to create an attachment.

AttachmentManager attachmentManager = ComponentManager.getInstance().getAttachmentManager();

for some reason, the ... 

MultiPartRequestWrapper mprw = (MultiPartRequestWrapper) ServletActionContext.getMultiPartRequest();

is resolving to null?

is there something special I need in my servlet config?

<servlet name="dataHandler" key="bamHandler" class="com.foo.BarServlet">
     <description></description>
     <url-pattern>/dataHandler</url-pattern>
</servlet>

Thanks again :)

For some reasong the mprw is comming back null? any ideas?

MultiPartRequestWrapper mprw = ServletActionContext.getMultiPartRequest();

Also, is there something special I need in my servlet config to support MultiPart Requests?

<servlet name="dataHandler" key="bamHandler" class="com.foo.BarServlet">
     <description></description>
     <url-pattern>/dataHandler</url-pattern>
</servlet>

Thanks again :)

Uh no, the ServletActionContext is part of webwork, well, it may be a utiloity class, but I've only used it inside an action. The patter to use is [HTML form] -> posts -> [Action] from which the above code works to extract the posted data.

Not to say your approach woudn't work, but Ive not had a compelling reason to even try, this works.
