I having difficulty sequencing the class path for the jars, url for Microsoft SQL Express 2019 into a java method. I haven’t been able to connect the drivers to open and execute sql file within java module, the new JDBC Requirements is causing a run error. This also occurwhen running on access. Can some provided a thorough explanations so I can think of what I might have coded in the connection url.

I'm trying to connect to live mssql database directly but I got the erro
"07-26 16:27:25.407: W/System.err(7136): java.sql.SQLException: Charset 0x0404E00000/MS950 is not supported by the JVM."
Here is the sample program I used by just changing the address/name/pw of the database.
https://github.com/alkber/AndroidByExample/tree/master/AndroidMSSQL2008
This problem is due to the JVM installed on your server.
It's caused by a limited language-only package (like US/English-only package).
You have to change the JVM to resolve this problem.
Reinstallaing JVM with complete language package should resolve your issue.
You shouldn't use jdbc for best coding and performance. Try to webservices.
Using jtds 1.2.5 I have this error when I stablish a connection: "No message resource found for message property prop.sokeepalive"
At first, I was using 1.2.2 version but I have this error message. "Error getting jdbc connection: The USE database statement failed because the database collation Serbian_Latin_100_CI_AS is not recognized by older client drivers. Try upgrading the client operating system or applying a service update to the database client software, or use a different collation. See SQL Server Books Online for more information on changing collations."
As solution, I tried to use 1.2.5 version getting the error mentioned at the beggining.
I was looking for hints in jtds documentation, but I can not resolve the problem.
any ideas?
Thanks in advance.
Try running client JVM with -Duser.language=en -Duser.region=US -Duser.country=US options.
This would switch to everywhere-supported US locale.
Maybe this easy solution would be acceptable in your case.
At least, this would reveal if the problem is in lack of i18n messages resource bundle for current locale in jtds package, as I guess.
Update
Try to just copy jtds.jar/net/sourceforge/jtds/jdbc/Messages.properties and add it to classpath or right inside jtds.jar as net/sourceforge/jtds/jdbc/Messages_sr_RS.properties.
Some explaining links:
Message bundle choosing process
net.sourceforge.jtds.jdbc.Messages source
http://www.localeplanet.com/java/sr-RS/
Update 2
Message bundle choosing process should switch to default provided resource anyway.
My second guess is that Messages.properties of jtds package gets eclipsed by some unrelated file with the same name.
Check your classpath.
You should be able to debug net.sourceforge.jtds.jdbc.Messages in order to find what's happening on for sure.
I have tried other jtds versions. from 1.2.2 yo 1.3.1 (recompiled to java 1.6) and all of them has the same error.
"Error getting jdbc connection: The USE database statement failed because the database collation Serbian_Latin_100_CI_AS is not recognized by older client drivers. Try upgrading the client operating system or applying a service update to the database client software, or use a different collation. See SQL Server Books Online for more information on changing collations."
Perhaps jdts does not support this collation.
I am trying to connect to a db2 database in Java. Below the driver and the connection string and the driver details i am giving
Class.forName("COM.ibm.db2.jdbc.net.DB2Driver");
String url="jdbc:db2://hostname:portnumber/databasename";
sourceConnection=DriverManager.getConnection(url,"username","password");
But I am getting the below exception
"COM.ibm.db2.jdbc.DB2Exception: [IBM][JDBC Driver] CLI0615E Error receiving from socket, server is not responding. SQLSTATE=08S01"
I also tried changing the connection string to
String url="jdbc:db2:hostname:portnumber/databasename";
Still it is resulting the same exception above while trying to get the Connection.
And i have tried the below option also using JDBC app driver
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
DB2DataSource db2ds = new DB2DataSource();
db2ds.setServerName("hostname");
db2ds.setPortNumber(portnumber);
db2ds.setDatabaseName("databasename");
db2ds.setUser("username");
db2ds.setPassword("password");
sourceConnection=db2ds.getConnection();
For the above two connection I used the jar "db2java.jar"
And i have tried using the JCC driver:
Class.forName("com.ibm.db2.jcc.DB2Driver");
String url="jdbc:db2://hostname:portnumber/databasename";
sourceConnection=DriverManager.getConnection(url,"username","password");
For this connection i have added the below jars
1)db2jcc.jar
2)db2jcc_license_cu.jar
This time around I am getting the below error,
"com.ibm.db2.jcc.am.go: [jcc][t4][201][11237][3.57.82] Connection authorization failure occurred.
Reason: Security mechanism not supported. ERRORCODE=-4214, SQLSTATE=28000"
I tried to connect to the same db2 source using "Quest for DB2" tool and the connection was successful.
Am i missing something in the code and is it a problem with DB2 drivers or connection string?
Can someone please guide me.
Thanks in advance.
Cause:
If the DB2® instance where InfoSphere Optim Performance Manager is running has the authentication configuration parameter set to DATA_ENCRYPT, you cannot log in to the web console.
Resolving the problem:
Do the following steps:
On the DB2 instance where Optim Performance Manager is running, set the authentication configuration parameter to SERVER by issuing the following command:
db2 update dbm cfg using authentication server
Restart the DB2 instance and InfoSphere Optim Performance Manager.

Your first two attempts were not supposed to work. You're using the JCC driver URL format, so it wouldn't be valid for either "net" or "app" drivers, which are deprecated anyway.
Use the JCC driver (com.ibm.db2.jcc.DB2Driver) and the URL format of "jdbc:db2://hostname:portnumber/databasename" and see this technote for the solution to the "Security mechanism not supported" problem. In short, you need to use a supported JDK.
I am C# developer and I don't know much about Java, normally in C# when I wanna connect to a database I use the following command:
static SqlConnection cn = new SqlConnection(#"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True");
I read a tutorial about making database connection (Sql Server 2008) in java in MSDN saying that the address must be declared this way:
String connectionUrl = "jdbc:sqlserver://localhost:1433;" + "databaseName=JavaDB;user=UserName;password=*****";
I would like to if there's any way to declare the url the way I do in C#, I mean instead of
"jdbc:sqlserver://localhost:1433;"
I directly point to the database
"AttachDbFilename=|DataDirectory|\Database.mdf;"
thanks
The first part of the URL is prescribed by the JDBC specification, so all drivers will follow the structure jdbc:<vendor-identifier>:<vendor-specific-url>.
In Java creating the connection (at least via java.sql.DriverManager) is independent of the actual Driver implementation that creates the connection (in C# you create a typed vendor-specific connection).
The first part, jdbc:<vendor-identifier> is used as a selection mechanism so a Driver can quickly decide if it will accept an URL or not. Technically multiple driver implementations could accept an URL and create the connection. The <vendor-identifier> is usually the name of the database or company.
The <vendor-specific-url> will usually follow normal URL conventions (MS SQL Server JDBC URLS are an exception to that).
The format of the Microsoft JDBC driver is:
jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]
See: Building the Connection URL.
Technically, Microsoft could have allowed only the database name in their <vendor-specific-url> and imply that it uses localhost but they decided not to do that.
The official documentation of the SQL JDBC driver does not mention any such thing
http://msdn.microsoft.com/en-us/library/ms378428.aspx
http://msdn.microsoft.com/en-us/library/ms378672(v=sql.110).aspx
so I assume it is not possible
I need to develop an application that connects to various DSN's using the Microsoft ODBC drivers. I have developed the application in Eclipse and it seems to work properly. The connection succeeds and I am able to view table data.
However when I export the project to a runnable jar file (using Eclipse) the functionality fails for Oracle. It is unable to establish connectivity with the Oracle connection string. It still works for SQL server but fails in case of Oracle. I'm unable to figure out the cause as the same ODBC drivers are being used for both Oracle and SQL-Server. More mystifying is that it runs properly on Eclipse. Since im using the ODBC drivers I don't believe the problem is because of an external jar file.
The driver is sun.jdbc.odbc.JdbcOdbcDriver and connection string is like jdbc:odbc:oratest;user=fell;password=pass.
I'm getting the following exception
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6958)
Can you please help me figure what the problem might be?
Thanks in advance,
Fell
Create a System DSN.
java.sql.Connection cn;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
cn=java.sql.DriverManager.getConnection("jdbc:odbc:dsn_name","user","pass");
Check the classpath in the eclipse project
