Example 19 with QueryEngineHTTP

use of org.apache.jena.sparql.engine.http.QueryEngineHTTP in project jena by apache.

the class TestQuery method query_construct_conneg.

// Conneg tests:
// These use independent connection pooling.
// Sharing pooling too much leads to lock up if the list is long (contentTypeTriXxml seems significant)
// Hence: try (CloseableHttpClient client = HttpOp.createPoolingHttpClient()) { ... qExec.setClient(client); ... } 
@Test
public void query_construct_conneg() throws IOException {
    try (CloseableHttpClient client = HttpOp.createPoolingHttpClient()) {
