[SalesForce] Bulk data update in Salesforce from External System

to set the sessionId header you want

req.setHeader("X-SFDC-Session", result.sessionId);

see the docs for an example request. (the Bulk API uses something different than the regular REST API).

Also, look a the response body you get from your request, it'll have more info on why its wrong, e.g. when i make a request with the same path you have, i get

> GET /services/async/u/10.0/job/123/batch/123 HTTP/1.1
> User-Agent: curl/7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8x zlib/1.2.5
> Host: na1.salesforce.com
> Accept: */*
> X-SFDC-Session: [SomeSessionId]
>
< HTTP/1.1 400 Bad Request

The docs also have details on the correct URI patterns to use.

It looks like that's the debug trace file, traceLogs.txt. Unfortunately, the sample isn't very clear - bulkConnection.getQueryResultStream() returns the actual data as an input stream. You need to extend your code to

• Create a CSV file
• Get an output stream for the CSV file
• Read data from the input stream returned by bulkConnection.getQueryResultStream() and write it to the output stream.

Once you have it all working, you will probably want to suppress creation of the trace file by changing

config.setTraceMessage(true);

to

config.setTraceMessage(false);
