Upload file issue
Hi,
Does anyone have any ideas that the below errors are happening due to line 59 & 71, for my app by Jdev 11.1.1.5? public String UploadImage() { UploadedFile myfile = (UploadedFile)this.getFile(); BindingContext bindingctx = BindingContext.getCurrent(); BindingContainer bindings = bindingctx.getCurrentBindingsEntry(); DCBindingContainer bindingsImpl = (DCBindingContainer)bindings; DCIteratorBinding iter = bindingsImpl.findIteratorBinding("UserTabView1_1Iterator"); Row row = iter.getCurrentRow(); 59 row.setAttribute("pict", createBlobDomain(myfile)); 60 61 return null; 62 } 63 64 private BlobDomain createBlobDomain(UploadedFile file) { 65 66 InputStream in = null; 67 BlobDomain blobDomain = null; 68 OutputStream out = null; 69 70 try { 71 in = file.getInputStream(); 72 ... Caused by: java.lang.NullPointerException at view.backing.UploadImageClass.createBlobDomain(UploadImageClass.java:71) at view.backing.UploadImageClass.UploadImage(UploadImageClass.java:59) Many Thanks & Best Regards, HuaMin |
Any advice to this?
Many Thanks & Best Regards, HuaMin |
please try to use [code][/code] to keep formatting of your code.
NullPointerException means you tried to use the class file (line 71: file.getInputStream()), but probably it was null. You would need to check if this call UploadedFile myfile = (UploadedFile)this.getFile(); returned valid myfile. _____________________________________ If someone helps you, or you approve of what's posted, click the "Add to Reputation" button, on the left of the post.
