MYSQL / Spring Hibernate: Connection has already been closed. So, I want to do 32 write operations under one @Transactional. I have set maxActive connections as "100", maxIdle as "50" (which I believe are quite high), maxTimeout is set to 150000 and removeAbandonedTimeout = 3000.
It seems column size for CaseFileDataLog.itemValue is limited to only 255 bytes. There is a requirement to have more data, can we increase the column size? for e.g 1024 Executing a Case fails with the following exception (using MS SQL Server): 2018-10-27 13:48:01,808 WARN [org.jbpm.process.audit.VariableInstanceLog] (default task-10) Variable content was trimmed as it was too long (more than

Package org.springframework.orm.hibernate5. Package providing integration of Hibernate 5.x with Spring concepts. Contains an implementation of Spring's transaction SPI for local Hibernate transactions. This package is intentionally rather minimal, with no template classes or the like, in order to follow Hibernate recommendations as closely as Access to a lazy-loaded object outside of the context of an open Hibernate session will result in this exception. It’s important to understand what Session , Lazy Initialisation, and Proxy Object are, and how they come together in the Hibernate framework:
I'm using mySQL as database, On release of batch it still contained JDBC statements Exception in thread "main" org.hibernate.exception.SQLGrammarException: could
An example of retrieving data from a table having columns column1, column2 ,column3 column4, cloumn1 and 2 hold int values and column 3 and 4 hold varchar(10). import java.sql.*; // need to import this as the STEP 1. When I try to deploy my app to a remote tomcat server, I get the following error: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springfram 1. This is not related to Hibernate but a general concept in Java. catch (HibernateException e) { //fail e = (Throwable)e; //fail e.printStackTrace (); } The reference e was originally of type HibernateException and inside catch block now you are trying to cast it to one of its parent class Throwable which is not compatible. On local machine all works fine. But when I tried to do get request on server machine, hibernate throws the following exception: JDBC exception on Hibernate data access: SQLException for SQL [n/a]; SQL state [HY000]; error code [1030]; could not extract ResultSet; nested exception is org.hibernate.exception.GenericJDBCException: could not VU9xrr.
