I'm trying a sample hibernate program, to connect to MS SQL DB and execute some sql.
I've created hbm and cfg.xml files but while executing I'm getting following exception.
java.sql.SQLException: No suitable driver

Caused by: org.hibernate.HibernateException: Dialect class not found: net.sf.hibernate.dialect.SQLServerDialect
I'm not getting whether I have missed any jar files or is there any other problem.
Please help.
Thanks.

Dialect class not found: net.sf.hibernate.dialect.SQLServerDialect
You need to put the Jar, containing this class, in your class paht.
May the problem is, that the dialect you need is: org.hibernate.dialect.SQLServerDialect which is aviable in the hibernate core jar.
have you add Mssqlserver.jar in your class path . or check your connection url

I am trying to connect hibernate with PostgreSQL(10.2) using the org.hibernate.dialect.PostgreSQLDialect and by default hibernate(5) is adding TYPE=MYISAM when creating a table in PostgreSQL. Then it was throwing this error Caused by: org.postgresql.util.PSQLException: ERROR: syntax error at or near "type" in Eclipse. I know that TYPE is changed to ENGINE in MYSQL present versions but I want to use PostgreSQL. Any possible ways of changing TYPE=MYISAM in hibernate classes or any other solutions? Please help me to fix this.
Thank you.
So I got sort of strange situation. I have Spring webapp and in it I have JNDI datasource that I have defined in tomcat's server.xml to connect to mysql database
I have mysql-connector-java 5.1.2 in my Maven pom.
Application works when I start it from localhost, but when I deploy it to remote tomcat it is not getting the call to the database.
This Exception occurs :
Couldnt execute sql CALL shareholders_company_list(?)
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Unable to create correct SQLException class instance, error class/codes may be incorrect. Reason:
** BEGIN NESTED EXCEPTION **
java.sql.SQLException
MESSAGE: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException
STACKTRACE:
java.sql.SQLException: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException
Is there away to avoid this ClassNotFoundException, so that I can get full stack trace, since it seems that explicit error why this happens is in MySQLNonTransientConnectionException, and I can't seem to reach it.
import required version(if you don't have any preference go for latest) of mysql-connector-java-latestVersion.jar under tomcat\lib

org.hibernate.SessionException: Error! Please, check your JDBC/JDNI Configurations and Database Server avaliability. Could not open or put a Hibernate Session in ValueStack: JDBC Driver class not found: com.mysql.jdbc.driver
You have wrong driver class configured. The correct class name com.mysql.jdbc.Driver. See the example of usage here.
I am making a simple mapping program in hibernate.
I am facing an error:
JDBC Driver class not found: com.mysql.jdbc.Driver
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
It gives an error on this line:
Session session = HibernateUtil.getSessionFactory().openSession();
hibernate.cfg.xml is correct. In the same configration other program are run. but this program give me error.
What is the reason that it throws this error?
You need to get a MySQL driver and put it on your classpath.
A commonly-used driver is MySQL Connector/J. It can be found here. Extract the package and make the jar available to your application.
I am using BLOBs in my SPRING-Hibernate application its, giving "java.lang.ClassNotFoundException: oracle.sql.BLOB" in case of ORACLE as a database!
Exactly I am getting following:
Caused by:
org.springframework.dao.InvalidDataAccessApiUsageException: Couldn't initialize OracleLobHandler because Oracle driver classes are not available. Note that OracleLobHandler requires Oracle JDBC driver 9i or higher!
nested exception is java.lang.ClassNotFoundException: oracle.sql.BLOB
You need ojdbc.jar (or similar) on your classpath (this is the Oracle JDBC driver)
Here is a list of drivers, pick the one that suits your environment.
Maybe your OSGI manifest does not export the right packages?
