Hi everybody! I have some troubles with parsing simple plain-text form fields in Restlet v1.1
The form looks like <form action="/restletServlet" method="post" enctype="multipart/form-data"> <textarea name="simpleField" rows="10" cols="100">Simple text content</textarea> <input type="submit" value="post"> </form> I've tried to parse multipart request from my resource as in the example at http://wiki.restlet.org/docs_1.1/13-restlet/28-restlet/64-restlet.html page (with some simplification): ---------------- // 1/ Create a factory for disk-based file items DiskFileItemFactory factory = new DiskFileItemFactory(); factory.setSizeThreshold(1000240); // 2/ Create a new file upload handler RestletFileUpload upload = new RestletFileUpload(factory); try { upload.parseRequest(request); // LINE X } catch (FileUploadException e) { e.printStackTrace(); } ---------------- The following error occurs: java.lang.NullPointerException at org.apache.commons.fileupload.MultipartStream$ItemInputStream.makeAvailable(MultipartStream.java:976) at org.apache.commons.fileupload.MultipartStream$ItemInputStream.read(MultipartStream.java:886) at java.io.InputStream.read(Unknown Source) at org.apache.commons.fileupload.util.Streams.copy(Streams.java:96) at org.apache.commons.fileupload.util.Streams.copy(Streams.java:66) at org.apache.commons.fileupload.MultipartStream.readBodyData(MultipartStream.java:592) at org.apache.commons.fileupload.MultipartStream.discardBodyData(MultipartStream.java:618) at org.apache.commons.fileupload.MultipartStream.skipPreamble(MultipartStream.java:637) at org.apache.commons.fileupload.FileUploadBase$FileItemIteratorImpl.findNextItem(FileUploadBase.java:984) at org.apache.commons.fileupload.FileUploadBase$FileItemIteratorImpl.<init>(FileUploadBase.java:965) at org.apache.commons.fileupload.FileUploadBase.getItemIterator(FileUploadBase.java:331) at org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:351) at org.restlet.ext.fileupload.RestletFileUpload.parseRequest(RestletFileUpload.java:104) at myPackage.MyResource.myPostRepresentation(MyResource.java:LINE X) Also, when I've tried pure Apache code instead of code above: ---------------- // Create a factory for disk-based file items FileItemFactory factory1 = new DiskFileItemFactory(); // Create a new file upload handler ServletFileUpload upload = new ServletFileUpload(factory1); try { upload.parseRequest(ServletCall.getRequest(request)); // LINE X } catch (FileUploadException e) { e.printStackTrace(); } ---------------- , I have following error: org.apache.commons.fileupload.FileUploadException: Stream closed at org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:385) at org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(ServletFileUpload.java:126) at myPackage.MyResource.myPostRepresentation(MyResource.java:LINE X) ...

My question is - Does Restlet 1.1 supports parsing of simple text fields from forms encrypted as 'multipart/form-data'? And if it does, any ideas what I have doing wrong? Thanks! ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2656033
