{code:java}
@Test
public void testUdf() throws Exception {
    client.getOrCreateCache(new CacheConfiguration<Integer, Object>("emp")
        .setSqlSchema("EMP")
        .setIndexedTypes(Integer.class, Employer.class));

    client.getOrCreateCache(new CacheConfiguration<Integer, Object>("udf")
        .setSqlSchema("UDF")
        .setSqlFunctionClasses(MulFunctionsLibrary.class));

    for (int i = 0; i < 3; i++)
        client.cache("emp").put(i, new Employer("emp" + i, (double)i));

    assertQuery("SELECT udf.mul(_key, _key) FROM emp.Employer")
