带有效免费许可证的JDataConnect许可证问题(JDataConnect license issue with valid free license)

带有效免费许可证的JDataConnect许可证问题(JDataConnect license issue with valid free license)

多年以前，我们一直使用JDataConnect从Java访问Microsoft Access数据库。 对于迁移项目，我们暂时考虑再次使用它。 在此期间，原则上可以进行远程访问。 一年前我做过一次成功的测试。

今天我正在使用以下免费许可在另一台机器上重试： http ： //www.jnetdirect.com/free-software/jdataconnect-single.html

我已经下载并安装了3.679.232 JDCSetup_4_0.exe

在端口1150上打开防火墙之后我原则上可以使用JData2_0.sql。$ Driver作为驱动程序和连接字符串连接，如：

jdbc:JDataConnect:1150//leto/c:\\y_wf\\data\\smartCRM\\smartCRM.mdb

然后我收到错误信息：

Attempt 1, Connect to JDataServer on server leto port:1150 Result was: java.sql.SQLException: ServerException:You should upgrade the license for this version. The current License is valid only for version 3 SQLState: 01000 VendorError: 0

我很困惑因为我使用了JnetDirects网页上的许可证密钥。 似乎没有可用的版本3下载。 这可能会导致情况失败？

JDataConnect has been used by us many years ago to access Microsoft Access Databases from Java. For a migration project we are tentatively thinking about using it again. In the meantime remote access is possible in principle. I had one successful test a year ago.

Today I am retrying on a different machine with the free license from: http://www.jnetdirect.com/free-software/jdataconnect-single.html

I have downloaded and installed 3.679.232 JDCSetup_4_0.exe

After opening the firewall on port 1150 I can in principle connect using JData2_0.sql.$Driver as a driver and a connection string like:

jdbc:JDataConnect:1150//leto/c:\\y_wf\\data\\smartCRM\\smartCRM.mdb

then i get the error message:

Attempt 1, Connect to JDataServer on server leto port:1150 Result was: java.sql.SQLException: ServerException:You should upgrade the license for this version. The current License is valid only for version 3 SQLState: 01000 VendorError: 0

I am confused since I used the license key from the JnetDirects webpage. There seems to be no version 3 download available. What might be going on here that makes the situation fail?

最满意答案

JNetDirect支持回答了以下问题：

经过进一步验证后，我注意到（并更正了）在下载文件之前在下载页面上提供的密钥，而主JDataConnect页面是正确的（下面的红色的那个），另一个页面上提供的那个（Wolfgang用过）有1个不同的数字。 它已得到纠正。

JNetDirect support answered the following:

After further verification, I noticed (and corrected) that while the key provided on the download page before the file is downloaded and the main JDataConnect page was the correct one (the one in red below), the one provided on another page (which Wolfgang used) had 1 different digit. It has been corrected.
