java.lang.NoSuchFieldError: name at run time in hibernate project

java.lang.NoSuchFieldError: name at run time in hibernate project - java

Trying my hand at my first hibernate (JPA annotations) console application. And I've been running around in circles trying to sort out dependencies, it feels like I'm trying to build a house of cards in a hurricane. Also, I'm using maven, I was under the impression that that maven is supposed to prevent this type of thing.. Anyways this is the error that I'm getting:
Exception in thread "main" java.lang.NoSuchFieldError: name

If I can get some help on this I shall be eternally grateful!

You have two different version dependency for hibernate entity-manager. This will not work. Remove one of them
<dependency>
<groupId>hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.4.0.GA</version>
<exclusions>
<exclusion>
<artifactId>ejb3-persistence</artifactId>
<groupId>org.hibernate</groupId>
</exclusion>
</exclusions>
</dependency>
........................
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.10.Final</version>
</dependency>

try either deleting your slfj dependency entry in your pom, your force the hibernate dependency to exclude it. Hibernate wants to use its own.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.6.10.FINAL</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
</exclusions>
<scope>compile</scope>
</dependency>
etc. Add the same exclusions for hibernate-core etc.

Seems to be a version conflict in the dependencies for artifact slf4j-log4j12.
You could check the output of "mvn dependency:tree" to check for a conflict.

When I try to run programm I got an exeption:java.sql.SQLException: Access denied for user 'root'#'localhost'
And another one:

I think it's because due to thirst one.

It works when I create a new user. Thanks to Ankit

Your configuration seems right.
Try this from Querydsl's documentation
If you use Eclipse, run mvn eclipse:eclipse to update your Eclipse project to include target/generated-sources/java as a source folder.
Now you are able to construct JPA query instances and instances of the query domain model.

How to mapping subquery in select with jpa

I am using spring ,jpa, hibernate,mysql , java 8,.In Dao (which is inteface and extends JpaRepository)
MyTable class
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;
#Entity
#Table(name = "MY_TABLE")
public class MyTable {
#Id
#Column(name = "ID")
private long id;
#Column(name = "ITEM_NAME")
private String itemName;
#Column(name = "ITEM_PRICE")
private int itemPrice;
#Transient
private int col1;
public MyTable() {
}
public MyTable(long id, String itemName, int itemPrice, int col1) {
super();
this.id = id;
this.itemName = itemName;
this.itemPrice = itemPrice;
this.col1 = col1;
}
public long getId() {
return id;
}

MY_TABLE
CREATE TABLE `my_table` (
`ID` bigint(20) NOT NULL,
`ITEM_NAME` varchar(255) DEFAULT NULL,
`ITEM_PRICE` int(11) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
I try to simplify my problem.I try to get col1 value but i can't find out how should be col1 attribute in entity. Other values can be gotten in entity.
If i use col1 attribute without #Transient , it will work , but col1 is not persistant(Also findAll() not working because there isn't col1 column on db). What should i do ?

you have many options but you could try this the following steps if you are using JPA 2.1:
1) Create a suitable DTO which should include properties that will take the results of your query:
"SELECT mt.*, (select count(1) from anotherTable ) as col1 from MY_TABLE mt"
2) In the MyTable entity, map the native query to your DTO using the #SqlResultSetMapping and #ConstructorResult annotations (a simple search on google will give you lots of usefull info on its usage).(See http://docs.oracle.com/javaee/7/api/javax/persistence/SqlResultSetMapping.html)
3) Modify the MyTableDao to use the native query you created in step 2.
I hope this helps. Goodluck :)

I need to consume json object dynamically so that it gets stored to my database table. Any help would be apreciated. But whenever I pass json object to the resource mapping, it says error 415, media unsupported.

java.lang.NoSuchFieldError: name at run time in hibernate project - java

Seems to be a version conflict in the dependencies for artifact slf4j-log4j12. You could check the output of "mvn dependency:tree" to check for a conflict.
