我正在开发一个可以打开使用Crystal Reports生成的报表的Web应用程序。我已经关注了有关如何配置连接的其他帖子：
final Tables tablas = databaseController.getDatabase().getTables();
for (final ITable table : tablas) {
ITable t = (ITable)table.clone(true);
t.setQualifiedName(conexionBaseDatos.getIdentificadorNombreTabla() + table.getName());
final IConnectionInfo connectionInfo = table.getConnectionInfo();
final PropertyBag propertyBag = new PropertyBag();
propertyBag.put(TRUSTED_CONNECTION, "false");
propertyBag.put(SERVER_TYPE, "JDBC (JNDI)");
propertyBag.put(USE_JDBC, "true");
propertyBag.put(DATABASE_DLL, "crdb_jdbc.dll");
propertyBag.put(JNDI_OPTIONAL_NAME, conexionBaseDatos.getName());
propertyBag.put(CONNECTION_URL, conexionBaseDatos.getUri());
propertyBag.put(DATABASE_CLASS_NAME, conexionBaseDatos.getDriver());
connectionInfo.setAttributes(propertyBag);
connectionInfo.setUserName(conexionBaseDatos.getUser());
connectionInfo.setPassword(conexionBaseDatos.getPass());
connectionInfo.setKind(ConnectionInfoKind.SQL);
t.setConnectionInfo(connectionInfo);
try {
databaseController.setTableLocation(table, t);
} catch (final Exception e) {
LOGGER.error("Error.", e);
throw new ErrorGenerarInformeException(e);
}
}
我认为一切都是对的，但是控制台正在向我显示下一个错误：

我只是想将数据库中的字段绘制到报告中。当然报告的字段格式正确。我也有这个痕迹

我需要帮助。
编辑：我认为问题不在于连接

答案 0 :(得分：0)
最后，我在这一行解决了我的问题：
t.setQualifiedName(conexionBaseDatos.getIdentificadorNombreTabla() + table.getName());
函数getIdentifacadorNombreTable返回null，因此报告设置了nullName，如name。我设置了这个变量，知道工作正常。
