RuntimeException无法映射到响应，重新抛出到HTTP容器com.hp.hpl.jena.update.UpdateException

Question

我有一个REST服务，用于将数据发送到三元组：

VirtGraph virtGraph = new VirtGraph ("jdbc:virtuoso://localhost:1111", "demo", "demo");
Model virtModel = new VirtModel(virtGraph);
VirtuosoUpdateRequest vur = VirtuosoUpdateFactory.create(str, virtGraph);
vur.exec();
virtGraph.close();

虽然存储了数据，但我得到的答案是：

com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException
SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
com.hp.hpl.jena.update.UpdateException: Convert results are FAILED.:
    at virtuoso.jena.driver.VirtuosoUpdateRequest.exec(VirtuosoUpdateRequest.java:72)

所需的所有库都在项目的Web文件夹中。有什么想法吗？
