Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1.I am getting a 15mb file in response from soap web service as a Vector<Byte>.
2.but i am getting the out of memory error from Ksoap library when it is trying 
to parse the response.

What is the expected output? What do you see instead?
I am expecting that Ksoap library will return me a Vector<Byte> after response 
parse.
While I am getting this exception

What version of the product are you using? On what operating system?
I am using ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar

Please provide any additional information below.
Is there any way to send a huge file in KSoap2 as attachment .or any other way 
to deal with large size data.

Try with the latest 3.0.0 version .. there were some enhancements regarding 
large response bodies including saving to a file since 2.5.8

Adding my two cents here. File content can be embedded in Soap response (XML) 
in Soap Envelope (in content area of HTTP Response) but that might cause 
problem of OOM as XML is first taken into memory and then parsed. 

We need to have file sent as attachment (Content-Type: Multipart/Related) 
separate from the Soap Envelope. See this link:
http://www.w3.org/TR/SOAP-attachments

We need to explore ksoap2 library if they are able to handle such a response 
where attachment can be read as it is streamed.
