Error while sending information through POST WS

[Mario Barón]

Hey guys,

I'm suddenly getting an error that I was getting about a year ago which is reported in this discussion post. But this time I am using the solution specified there by using the bui9ld request body method:

protected void buildRequestBody(OutputStream os) throws IOException {

            if(shouldWriteUTFAsGetBytes()) {
                os.write(payload.toString().getBytes("UTF-8"));
            } else {
                OutputStreamWriter w = new OutputStreamWriter(os, "UTF-8");
                w.write(payload.toString());
            }
    }

 What could causing this problem? it is also somnething quite recent it seems, it may be due to something you did server side, maybe?

Please  I appreciate your fast response to this matter as it is quite urgent to solve this.

Hi,
under which OS?
Does this happen in the simulator/device and which block is executed?

[Mario Barón]

Hey Shai,

this is happenning on Android, this is not happenning on the simulator. The app is going through the shouldWriteUTFAsGetBytes() == true block of the If.

Hi,
what do you see in the network monitor?
If you write the bytes to a file and compare the binary file with the one produced in the simulator how do they differ?

[Mario Barón]

Hey Shai,

both files appear to be the same but the one on the device seems to be cut short. The JSON file I'm getting is something like this:

on the device:

Hi,
it should work pretty well. Both the simulator and Android would use the getBytes() method which should produce exactly the same result.
Maybe Chen has an idea.
