.jpg images via SOAP webservice using SQL Server as DB
I have some small images in .jpg format.
After some reading, I concluded my files were small enough to store in the
database but I was told to make the type varbinary(max) No problem so far
When I created my Entities JPA wanted to make it a byte[]. Seems no
problem.
I defined my DTO object byte[] No Problem.
In FlashBuilder, I use the WSDL Wizard to creat my service stuff as usual.
I noticed it created the ValueObject with a ByteArray type.
Here is my result handler
protected function getImagesResult_resultHandler(event:ResultEvent):void
{
dataList = new ArrayCollection();
if (event.result != null)
{
if (event.result is ArrayCollection)
{
dataList = getImagesResult.lastResult;
}
else
{
dataList.addItem(toDTO(event.result));
}
}
}
public static function toDTO(o:Object):ImageDTO
{
var thisDTO:ImageDTO = new ImageDTO();
thisDTO.id = o.id;
thisDTO.name = o.name;
thisDTO.width = o.width;
thisDTO.length = o.length;
thisDTO.height = o.height;
thisDTO.sideid = o.sideid;
thisDTO.pic = o.pic;
return thisDTO;
}
But when I run my app and I call getImages()
I get this error:
ReferenceError: Error #1065: Variable ByteArray is not defined.

Evidently, This is a bug in FlashBuilder.
So since I am using SOAP and Flashbuilder to create my service and
valueObjects.
How should I do images? Or is there a workaround to this problem?

Re: .jpg images via SOAP webservice using SQL Server as DB
Posted by CodeGirl <Mi...@yahoo.com>.
I had converted it to a string so I wouldnt crash when i ran it. So I added
a new variable called testpic.
Here are the DTO, Super_, and EntityMetadata for that valueObject

AW: .jpg images via SOAP webservice using SQL Server as DB
Posted by Christofer Dutz <ch...@c-ware.de>.
Hi,
I am sending image data as byte-array from BlazeDS to my Flex application without any problems. But I just checked the beginning of this thread ... as you are using SOAP I guess you will have to Base64 encode the data as the raw byte data could contain any XML character to mess up things.
Chris

This is not my area of expertise, but AIUI, you might be better off
getting the backend to send the image as base64 as suggested in the
article you linked to, but do it by getting the data type to match one of
the base64 types in this article:

I think if you can do that, the SOAPDecoder will convert the data to a
ByteArray properly. I think the way it is set up right now is throwing an
error because the generic decoder can't decode directly to ByteArray. I
think it needs to know that it is Base64-encoded.

Here is a suggested work around.
http://stackoverflow.com/questions/25255030/as3-loading-images-binary-xml-to-flash
What is an FLA?
I am guessing the suggestion here is in JPA on my backend, convert my
varbinary(MAX) to a String.
Let SOAP send it as a String. Let the Value Object be a String. Then when
I want to display the image,
I apply the decoder in the link above to convert the string to a ByteArray.
Of course I still need to figure out how I send the data from ByteArray to a
BinaryImage. I am new to using images. My apps are normally really plain.

Please post the code for the ValueObject. Or a link to the code.
Thanks,
