Question

尝试将ArangoDB (2.7.0)与Java驱动程序2.6.8一起使用时，我遇到了错误。想知道我是否遗漏了一些显而易见的事情。

此外，如果下面的错误报告了无法找到的集合名称，那将是非常好的，这与Oracle未找到的表格＃34;并且花费大量时间来确定在使用大型存储过程时丢失哪个表。

CollectionEntity vCollection = arangoDriver.createCollection("vertexCollection", new CollectionOptions().setType(CollectionType.DOCUMENT));
CollectionEntity eCollection = arangoDriver.createCollection("edgeCollection", new CollectionOptions().setType(CollectionType.EDGE));

List<EdgeDefinitionEntity> edgeDefinitions = new ArrayList<>();
EdgeDefinitionEntity edgeDefinition = new EdgeDefinitionEntity();
edgeDefinition.setCollection("edgeCollection");

List<String> from = new ArrayList<>();
from.add("vertexCollection");
edgeDefinition.setFrom(from);

List<String> to = new ArrayList<>();
to.add("vertexCollection");
edgeDefinition.setTo(to);

GraphEntity graph = arangoDriver.createGraph("myGraph", edgeDefinitions, null, true);

VertexEntity<Object> v1 = arangoDriver.graphCreateVertex("myGraph", "vertexCollection", new Object(), true);

arangoDriver.graphCreateVertex(...)投掷如下：

非常感谢任何帮助。

根据reply，以下声明丢失了！

edgeDefinitions.add（edgeDefinition）;

现在有效。

Java驱动程序抛出错误
