Problems connecting JDBC driver to MSSQL database

Question

We have a java web app that I am having some JDBC issues with. Last year, while on Java 7, we had no problem connecting to a SQL database on another server on the same network using sqljdbc4.jar. We upgraded our application to Java 8 this year and this is when problems arose. We updated the JDBC version to 4.2 (sqljdbc42.jar). The .jar file is included in our build path and this worked a year ago. We are using JBOSS 7.0 in the Eclipse-Luna IDE.

Now when we try to use the JDBC, we get a java.lang.ClassNotFoundException.

Connection conn = null;
String db_hostname = "test.fake.com";
String db_portNumber = "1433";
String db_name = "db";
String db_userid = "user";
String db_password = "password";
String db_final_string = "jdbc:sqlserver://" + db_hostname + ":" + db_portNumber + ";databaseName=" + db_name;
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
conn = DriverManager.getConnection(_db_final_string, _db_userid, _db_password);

This is the error we get due to Class.forName():

If anyone can offer any insight on how to get this correctly configured that would be most helpful because we have tried several combinations of tweaks already.

Answer 1

JBoss AS 7 is not compatible* with Java 8. You need to update to WildFly 8/9 .

---

Notes

^{* See more in AS 7 on Java 8 .}

Answer 2

You have to download compatible Microsoft JDBC Driver for SQL Server driver. You can find it inside msdn drivers.

https://msdn.microsoft.com/en-us/sqlserver/aa937724.aspx

this url should work.

Answer 3

I figured it out. I needed to make the jdbc driver a JBoss Module and include it in the standalone.xml as a global module.
