Probleme mit Hibernate Tools Installation

[Tawarien]

Hallo.

Ich versuche über den Eclipse Marktplace die Hibernate Tools zu laden und zu installieren.
Dummerweise bricht mir die Installation mit folgender Fehlermeldung immer ab:

Cannot complete the provisioning operation. Please change your selection and try again. See below for details.
Cannot complete the install because of a conflicting dependency.

Laut google lässt sich das Problem angeblich damit lösen, dass man Eclipse als Admin ausführt.
Hilft hier aber allerdings nix.

Guten Morgen,

https://issues.jboss.org/browse/HIBERNATE-123

hastes mal direkt über die Updatesite probiert?

http://download.jboss.org/jbosstools/updates/stable/

Wunderbar, darüber ließ sichs nach einigem hin und her dann installieren.

Danke!

 

[genodeftest]

Hi
bitte Thema als erledigt markieren!

Hi
bitte Thema als erledigt markieren!

Werde ich tun, allerdings ist direkt das nächste Problem aufgetaucht und ich denke ich führe das in diesem Thread fort und eröffne keinen neuen dafür, da es immer noch mehr oder minder damit zusammenhängt.

Also, die Installation hat soweit geklappt und nun versuche ich eine kleine Struktur abzubilden.


"Reading schema error: Getting database metadata" ist die Fehlermeldung und ich steh grad aufm Schlauch.

Ich füge mal die jeweiligen Codes ein, vielleicht überseh ich einfach nur was blödes, kann gut sein.

@Entity
@NamedQueries({
	@NamedQuery(name="test", query="SELECT * FROM User"),
	@NamedQuery(name="test2", query="SELECT * FROM User")})

public class User {
	
	private int id;
	private String nickname;
	private String firstname;
	private String lastname;
	private String password;
	private Movie movie;
	
	@Id
	@GeneratedValue
	public int getId() { return id; }	
	public void setId(int id) { this.id = id; }

	public String getNickname() { return nickname; }
	public void setNickname(String nickname) { this.nickname = nickname; }
		
	public String getFirstname() { return firstname; }
	public void setFirstname(String firstname) { this.firstname = firstname; }
	
	public String getLastname() { return lastname; }
	public void setLastname(String lastname) { this.lastname = lastname; }

	public String getPassword() { return password; }
	public void setPassword(String password) { this.password = password; }
	
	@OneToMany(mappedBy="user")
	public Movie getMovie() { return movie; }
	public void setMovie(Movie movie) { this.movie = movie; }

}

Die anderen beiden Entitys sind im Prinzip genauso aufgebaut.

 

[SE]

org.gjt.mm.mysql.Driver sollte nicht mehr verwendet werden. Es ist lediglich eine Wrapper-Klasse für com.mysql.jdbc.Driver und existiert nur noch damit alte Applikationen die diese Klassen noch verwenden auch mit neueren Versionen des Drivers arbeiten.

 

[sebastianb]

Guten Morgen,

was du zunächst tun kannst, ist den Logger etwas granularer einzustellen - vll spuckt er dann mehr aus. Zweitens ist mir nicht ganz klar für was die hibernate.properties sein soll, da sich ja durch die persistence.xml eine Gewisse Redundanz ergibt.

hibernate.connection.url=jdbc:mysql://localhost/filmkritik?

entferne mal das ? am ende.

Poste außerdem bitte mal einen Stacktrace bzw wo und wann die Exception Auftritt. Beim Hochfahren des Persistence-Contexts?

*EDIT* Darf ich fragen für was du Hibernate-Tools benötigst? Ich habe erst einmal darauf zurückgreifen müssen und da ging es um einen ganz speziellen Sondernfall.

Gruß

Sebastian

Ändert leider nix.
