Struts2 - multipart/related - HttpServletRequest#getParts not working

[Nikhil P Kookkiri]

I have request coming from another application which is
'multipart/related'. In the mutlipart request body, I am receiving
image/jpeg and application/xml. I suppose, I should be iterating over
the http part obtained from getPaths method in the HttpServletRequest
object and read the stream available on each of the parts. When I try
doing that, I am getting the following error:

java.lang.IllegalStateException: UT010057: multipart config was not
present on Servlet
ERROR [stderr] (default task-2)     at
io.undertow.servlet//io.undertow.servlet.spec.HttpServletRequestImpl.verifyMultipartServlet(HttpServletRequestImpl.java:523)
ERROR [stderr] (default task-2)     at
io.undertow.servlet//io.undertow.servlet.spec.HttpServletRequestImpl.getParts(HttpServletRequestImpl.java:512)
ERROR [stderr] (default task-2)     at
javax.servlet.api//javax.servlet.http.HttpServletRequestWrapper.getParts(HttpServletRequestWrapper.java:375)

Please let me know the best possible solution for this.

Here is what I am doing in the code:

    public class TestMultiPart extends ActionSupport implements
ServletRequestAware
    {
        private InputStream inputStream;
        private HttpServletRequest request;

    public String execute()
    {
        BufferedInputStream bis = null;
        BufferedOutputStream bos = null;
        try
        {
            Collection<Part> parts = request.getParts();
            for(Part part : parts)
            {
                String contentType = part.getContentType();
                System.out.println("Content type is: " + contentType);
                File file = getFileToDownload(getContentType(contentType));
                if(file != null)
                {
                    bis = new
BufferedInputStream(request.getInputStream());
                    bos = new BufferedOutputStream(new
FileOutputStream(file));
                    byte[] bytes = new byte[bis.available()];
                    while(bis.read(bytes) > 0)
                    {
                        bos.write(bytes);
                        bos.flush();
                        bytes = new byte[bis.available()];
                    }
                }
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ServletException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            if(bis != null)
            {
                try {
                    bis.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if(bos != null)
            {
                try {
                    bos.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }

        inputStream = new
ByteArrayInputStream("200".getBytes(StandardCharsets.UTF_8));
        return SUCCESS;
    }

    public InputStream getInputStream() {
        return inputStream;
    }

    public void setInputStream(InputStream inputStream) {
        this.inputStream = inputStream;
    }

    @Override
    public void setServletRequest(HttpServletRequest requestObject)
    {
        this.request = requestObject;
    }

}

This isn't Struts issue but your underlying servlet message. Anyway, what about trying Struts itself file upload feature. Then ask that another app to http post the file to a file upload action.

Hi Yesser, thanks for your response. Yes, it is the issue with the
servlet. I am suspecting that MutiPartConfig works only for
multipart/form-data and does not work with multipart/related. I passed
the request directly to HttpServlet instead of Sturts mapped Action with
@MultiPartConfig configured and I got the exception:
javax.servlet.ServletException: UT010016: Not a multi part request.
Almost all documentation I saw talks only about multipart/form-data.

I am assuming using Struts rest plugin also will not help in this case.
Kindly let me know.

Best regards,
Nikhil P kookkiri

I see Struts REST plugin has a handler for multipart request but it and even the whole Struts framework also talks only about multipart/form-data ;) Unfortunately it seems Struts doesn't know such content type at all. Anyway, some tips can be found in net via googling "UT010016: Not a multi part request".
