System.CalloutException: Web service callout failed: String length exceeds maximum: 1000000
Hello everyone.
I need to call a Webservice with multiple files (base64 encoded).
As I don't like dealing with WSDL, I decided to create the following class
global class MyWSClass{ webservice static Blob myWSMethod (List<Blob> inputs){ return null; } }
After that, I clicked on "Generate WSDL" and cleaned it a little bit (remove all headers but SessionHeader) and save it.
Then, I tried to use that WSDL to generate the Class that will use the webservice (using WSDL2Apex) that generates the following prototype.
... public String myWSMethod(String[] inputs) { ...
The webservice works fine as long as I don't send too much information.
If I send 3 files of 300k each, it throws the following exception
"System.CalloutException: Web service callout failed: String length exceeds maximum: 1000000"
on the line that calls to WebServiceCallout.invoke().
As the only field that depends on the files I choose is request_x and the response, I tried to change them to Blob (one, the other and both), but it didn't work.
Any idea?
Thanks
