e-sparqlEndpoint doesn't send correct MIME type #104

Closed jindrichmynarz closed 9 years ago

jindrichmynarz commented 9 years ago

Using e-sparqlEndpoint compiled from 71286036ff0a0089a6b77bb7d8827b1617b46f96 I found out that it fails with the Parliament RDF store (and presumably others) because it doesn't send correct MIME type (application/x-www-form-urlencoded, application/sparql-query, or application/sparql-update).

Execution failed because: Operation failed.eu.unifiedviews.dpu.DPUException: Operation failed.
