JavaDB连接错误（网络协议）
我正在尝试使用以下命令连接到 derby：
dbProperties.put("create", "true");
dbProperties.put("dataEncryption", "true");
dbProperties.put("encryptionAlgorithm", "DES/CBC/NoPadding");
dbProperties.put("encryptionKey", "1234567890123456");
dbProperties.put("securityMechanism", ClientDataSource.STRONG_PASSWORD_SUBSTITUTE_SECURITY);
// protocol is dbProperties.getProperty("derby.url", "jdbc:derby://localhost:1527/");
dbConnection = DriverManager.getConnection(protocol + dbName, dbProperties);
但出现错误：
无法建立连接，因为数据库名称 (...) 大于网络协议允许的最大长度。
有没有办法增加这个长度？
I'm trying to connect to derby using this:
dbProperties.put("create", "true");
dbProperties.put("dataEncryption", "true");
dbProperties.put("encryptionAlgorithm", "DES/CBC/NoPadding");
dbProperties.put("encryptionKey", "1234567890123456");
dbProperties.put("securityMechanism", ClientDataSource.STRONG_PASSWORD_SUBSTITUTE_SECURITY);
// protocol is dbProperties.getProperty("derby.url", "jdbc:derby://localhost:1527/");
dbConnection = DriverManager.getConnection(protocol + dbName, dbProperties);
but i get an error:
A connection could not be established because the database name (...) is larger than the maximum length allowed by the network protocol.
Is there a way to increase this length?

我不相信有办法增加长度；我认为这是 DRDA 标准指定的。
在您的示例中，“dbName”的值是多少？
并且，您可以发布您收到的实际异常吗？
I don't believe there is a way to increase the length; I think it is specified by the DRDA standards.
In your example, what was the value of 'dbName'?
And, can you post the actual exception you received?
