Description
basically i want to implement ORM using Hibernate with mysql 8.0.23 CE, for the creation of the
table i have configured it in the hibernate config file to be created:
but i'm encountered with the problem of "Could not create connection to database server"
as seen in the photos!
Entity
the representation of the table in mysql
import javax.persistence.Entity;
import javax.persistence.Id;
#Entity
public class User {
#Id
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

I am using Intelij idea and I am tying to make a simple connection with MySQL database with hibernate following a YouTube video.
For some reason my connection does not work and I get the following Errors:

I tried to find a solution for my problem online but I didnt find something to apply to my problem.

My problem was with the MySQL dependency I changed it to version 8.0.16 and worked.

I had this problem today too, I upgraded the package of mysql-connector-java for 8.0.23 and it worked fine.

Hibernate exception in creating a table

Please help me figure out the reason of this exception and how to resolve it.
Following a youtube tutorial, I am trying to create a table named 'alien' in a MySQL database named 'abc'. I am using the Hibernate ORM tool and Maven for this but Hibernate is throwing an exception
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table Alien (stud_id integer not null, age integer not null, marks integer not null, stud_name varchar(255), primary key (stud_id)) type=MyISAM" via JDBC Statement

}
}

In your persistence.cfg.xml file you should change the dialect to: org.hibernate.dialect.MySQL5InnoDBDialect
Or you can simply remove it, Hibernate should be able to detect it automatically
This should let Hibernate create InnoDB tables instead of MyISAM

Try using different dialects, if you are using MySQL v8 then use these dialects org.hibernate.dialect.MySQL8Dialect or com.mysql.cj.jdbc.Driver
error is with the dialect, you can check its generating type=MyISAM instead it should be ENGINE=MyISAM
type is deprecated from MySQL version 5, ENGINE is replaced from that version, since you are using MySQL8 dependency you need to use ENGINE
so the query should like this
create table Alien (columns names) Engine=MyISAM
use InnoDB engine instead of MyISAM
try executing the query in the console or workbench

Getting Hazelcast Native Client working with Hibernate 5.2.x

I'm trying to get Hazelcast working with Hibernate, but unless i use the super_client option, it doesn't start up.
According to the docs, Super Client should only be used if your app is on the same RAC or data center. For local, this will be the case, for production, they will most definitely be separated, so Native Client is the only option that will work for us.
Super Client is a member of the cluster, it has socket connection to
every member in the cluster and it knows where the data is so it will
get to the data much faster. But Super Client has the clustering
overhead and it must be on the same data center even on the same RAC.
However Native client is not member and relies on one of the cluster
members. Native Clients can be anywhere in the LAN or WAN. It scales
much better and overhead is quite less. So if your clients are less
than Hazelcast nodes then Super client can be an option; otherwise
definitely try Native Client. As a rule of thumb: Try Native client
first, if it doesn't perform well enough for you, then consider Super
client.
The best option for starting up Hazelcast seems to be using Docker:
docker pull hazelcast/hazelcast:3.10.4
docker run --name=hazelcast -d=true -p 5701:5701 hazelcast/hazelcast:3.10.4
And this is what it looks like once it is up and running, i double checked that the Hazelcast port, 5701, is exposed which it clearly is.
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
77a5a0bed5eb hazelcast/hazelcast:3.10.4 "bash -c 'set -euo p…" 3 days ago Up 6 hours 0.0.0.0:5701->5701/tcp hazelcast
The docker hub docs also mentions how to pass in JAVA_OPTS, i'm not sure if this is required or optional and what its purpose is, but this didn't help me get up and running:
-e JAVA_OPTS="-Dhazelcast.local.publicAddress=127.0.0.1:5701"
telnet 127.0.0.1 5701 successfully connects to localhost:5701, so i know the port is open. The docker docs doesn't mention what the default password is for this running Hazelcast instance, my assumption is that it's empty or that the password is dev-pass as mentioned in several older tutorials.

For Hazelcast, according to the docs, two dependencies are required,

<groupId>com.hazelcast</groupId>
<artifactId>hazelcast</artifactId>
<version>3.10.4</version>
</dependency>
<dependency>

<dependency>

<artifactId>hazelcast-client</artifactId>
<version>3.10.4</version>
</dependency>
The docs show the following links:
Clicking Hibernate 5 shows that hazelcast-hibernate52 is the correct dependency
When i click See here for details, i'm greeted with docs that look somewhat outdated:
Assuming there's only a typo, i go through to the example:
<!DOCTYPE hibernate-configuration SYSTEM "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.use_query_cache">false</property>
<property name="hibernate.cache.use_minimal_puts">true</property>
<property name="hibernate.cache.region.factory_class">com.hazelcast.hibernate.HazelcastCacheRegionFactory</property>
<property name="hibernate.cache.hazelcast.use_native_client">false</property>
<property name="hibernate.cache.hazelcast.native_client_hosts">127.0.0.1</property>

<property name="hibernate.connection.url">jdbc:derby:hibernateDB</property>
<mapping resource="Employee.hbm.xml"/>
</session-factory>
</hibernate-configuration>
In the example, Use Native Client is set to false, yet it is being configured, is this a typo or is this the correct configuration?
I'm trying out these settings on a standard Hibernate Postgres with C3P0 setup, here's my persistence.xml
<properties>

</properties>
Some params are entered programmatically via (this has been in use for ages, so i know it works, but adding it here just in case it helps make the code more clear)
fun paramsFromArgs(args: Array<String>): Map<String, String> {
val hibernateMap = mutableMapOf<String, String>()
args.forEach {
if (it.isNotBlank()) {
if (it.startsWith("hibernate") || it.startsWith("javax.persistence")) {
val split = it.split("=", limit = 2)
hibernateMap.put(split.get(0), split.get(1))
}
}
}
return hibernateMap
}
Now when i setup Second Level cache with Hazelcast:
paramsDefault.add("hibernate.cache.use_query_cache=true")
paramsDefault.add("hibernate.cache.use_second_level_cache=true")
paramsDefault.add("hibernate.cache.region.factory_class=com.hazelcast.hibernate.HazelcastCacheRegionFactory")
paramsDefault.add("hibernate.cache.provider_configuration_file_resource_path=hazelcast.xml")
paramsDefault.add("hibernate.cache.hazelcast.use_native_client=false")
paramsDefault.add("hibernate.cache.hazelcast.native_client_address=127.0.0.1")
paramsDefault.add("hibernate.cache.hazelcast.native_client_group=dev")
paramsDefault.add("hibernate.cache.hazelcast.native_client_password=dev-pass22222asfasdf")
paramsDefault.add("hibernate.cache.hazelcast.client.statistics.enabled=true")
Database.setupEntityManagerFactory("default",
Database.paramsFromArgs(paramsDefault.toTypedArray()))
Setting use_native_client to false like in the example doesn't seem to do anything, with the logs in debug mode, i'm not seeing anything Hazelcast related.
Switching it to true (which makes more sense considering it's being configured to have a password and IP address, it bombs out on startup.

I've also added a hazelcast.xml, not sure if this is needed or not:
<hazelcast

</hazelcast>
Is hibernate 5.2.x supported? (this ticket shows that the problems with Hibernate 5.2 was fixed, so my assumption is that it should work)
I want to run a stand-alone Hazelcast instance on one server and have multiple instances of the application use it as a central cache location, what am i missing from setup to make it work?
Update 1:
I've written a small piece of code that successfully connects to the local hazelcast instance (this is on my dev machine, same as with the rest of the code)
import com.hazelcast.client.HazelcastClient
import com.hazelcast.client.config.ClientConfig
import java.util.*
fun main(args: Array<String>) {
val config = ClientConfig()
config.getNetworkConfig().addAddress("127.0.0.1:5701")
val hazelcastInstance = HazelcastClient.newHazelcastClient(config)
val map = hazelcastInstance.getMap<String, String>("blah")
map.forEach { t, u ->
println(" $t -> $u ")
}
map.put("${Random().nextInt()}", "${Random().nextInt()}")
hazelcastInstance.shutdown()
}
To proof that it's storing and retrieving from cache, i restart the main method several times and each time the number of entries in blah increases
Run1:
No printlns
Run2:
1498523740 -> -1418154711
Run3:
1498523740 -> -1418154711
-248583979 -> -940621527
So Hazelcast is working correctly ...
Update 2:
I can now connect hazelcast from Hibernate, but it's throwing an exception for every lookup it has to do.
Removing hazelcast.xml from my classpath and then removing the group and password options, Hibernate is starting up and connecting.

Do i need to include some kind of JAR inside my Hazelcast Docker setup, or what is happening here?

Looks like you are attempting to use the loop back address from another sever and outside of the docker network.
You may want to try bridged to eliminate the docker network address translation.
Also since 0.0.0.0 is bonded thus all ip addresses should have Hazelcast listeners installed.
I would simplify and first validate Hazelcast. If you have enterprise then use the console application otherwise write a simple start server java main. And then attemp to connect with a client using a real IP address. Once this works then work on hibernate configuration.

Finally got it working, here's what was needed:
1: Make sure you have all three these dependencies, initially i was missing the first one, but for some reason, wasn't getting a ClassNotFound exception as expected. It doesn't seem to be a transitive dependency of either hazelcast-client or hazelcast-hibernate52
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast</artifactId>
<version>${hazelcast.version}</version>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-hibernate52</artifactId>
<version>${hazelcast-hibernate.version}</version>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-client</artifactId>
<version>${hazelcast.version}</version>
</dependency>
2: If your dev instance of Hazelcast doesn't have a password, don't specify the password. 127.0.0.1 works fine, no need to run on an external server while dev-ing.
paramsDefault.add("hibernate.cache.use_query_cache=true")
paramsDefault.add("hibernate.cache.use_second_level_cache=true")
paramsDefault.add("hibernate.cache.region.factory_class=com.hazelcast.hibernate.HazelcastCacheRegionFactory")
paramsDefault.add("hibernate.cache.hazelcast.use_native_client=true")
paramsDefault.add("hibernate.cache.hazelcast.native_client_address=127.0.0.1")
// paramsDefault.add("hibernate.cache.hazelcast.native_client_group=$ENV")
// paramsDefault.add("hibernate.cache.hazelcast.native_client_password=dev-pass")
3: Get rid of hazelcast.xml - after removing that hazelcast.xml file, Hibernate actually started up even though my hazelcast.xml file just had a one-liner in it saying use default config.
4: Make sure all entities are marked with Serializable, otherwise entities won't cache and cause an exception on the Hazelcast server itself.
#Table
#Entity
#BatchSize(size = 50)
#PersistenceContext(unitName = "default")
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region = "Tag")
class Tag(
name: String,
) : Serializable {
5: If your entity has #OneToMany, #ManyToOne or other entities inside of it, make sure those entities are Serializable as well.
6: Write a little script to ensure that your entities are caching:
import com.hazelcast.client.HazelcastClient
import com.hazelcast.client.config.ClientConfig
fun main(args: Array<String>) {
val config = ClientConfig()
config.getNetworkConfig().addAddress("127.0.0.1:5701")
val hazelcastInstance = HazelcastClient.newHazelcastClient(config)
val map = hazelcastInstance.getMap<Any, Any>("Tag")
println("=================")
map.forEach { t, u ->
println(" $t -> $u ")
}
println("=================")
hazelcastInstance.shutdown()
}
The above script will println all Tag entities currently in the cache
7: When starting up the Docker instance, make sure you've exposed the port, without the -p option, nothing will work.
docker run --name=hazelcast -d=true -p 5701:5701 -e JAVA_OPTS="-Dhazelcast.local.publicAddress=127.0.0.1:5701" hazelcast/hazelcast:3.10.4
8: Check the Hazelcast logs to see if your Java / Kotlin client is connecting:
docker logs -f hazelcast
You should see something like this when there's a connection:
Sep 13, 2018 9:05:06 PM com.hazelcast.client.ClientEndpointManager

These seems to be the crux of getting hazelcast hibernate working.

Is it possible to connect to oracle 12c pluggable database using Hibernate?

I have created a test application in Hibernate and using Oracle 12c as database. I was able to connect to "sys" user of main database. I am able to create, insert, update the tables in this DB. But I am unable to connect to pluggable database. Is there any way to connect to PDB using hibernate. Test is my main DB and pdborcl is my PDB. I also tried google for this, but there is no post on Hibernate and Oracle 12c, but nothing specific to PDB. There is this article which says there is no support for 12c. https://github.com/denimgroup/threadfix/issues/488 Is this true?
As far as my understanding of Oracle 12c goes, CDB is only for administration purposes and PDB will be the database used for application purposes.
hibernate.cfg.xml

When I try to connect to PDB by changing test to pdborcl it gives me below exception. I am able to ping both test and pdborcl from my system. I am also able to connect to both DBs using sqlplus from terminal.
I get below exception when I try to connect to PDB.

Your syntax is slightly wrong. Make sure you use the /SERVICE_NAME not the :SID.
For jdbc to connect to a pluggable database, :SID can no longer be used. (well, it can but don't go there)
Accessing an Oracle Database by service_name is the correct approach since Oracle 8i. And that is 100 it-years ago!
jdbc:oracle:thin:#localhost:1521/my_pdb_service_name
You will find available services by asking the listener
lsnrctl service
The sys account is a special account. Sys has the same meaning for the database as the root user has for the OS. You can do harm with these users! Instead create an application account/user.
create user mysuperapp identified by "Neverloginassys";
grant create session to mysuperapp;
