连接HSQLDB，没任何反应

[tpz_stamp]

hsqldb 2.2.9, hibernate 4.1.2, spring 3.1.1.
hsqldb以内存方式运行。
执行了一个查询，什么都查不到，但数据库明明有东西。。。也不像是数据库没连上。怎么回事呢。

Hibernate: select user0_.OBJ_ID as OBJ1_0_, user0_.FIRST_NAME as FIRST2_0_, user0_.VERSION as VERSION0_ from TB_USER user0_ where user0_.OBJ_ID=?
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

<property name="url" value="jdbc:hsqldb:mem:TestDB"/>url不对，应该是jdbc:hsqldb:hsql://localhost/类似的
