Welcome Edward & Robert! Good luck for your book!

I'm sorry, I did it to simplify the post.

User u = new User(); u.setAddress(new ArrayList<Address>()); u.set... Address a1 = new Address(); AddressPK pk1 = new AddressPK(); a1.setId(pk1); pk1.setIdUser(u.getIdUser()); pk1.set... a1.set... u.addAddress(a1); Address a2 = new Address(); AddressPK pk2 = new AddressPK(); a2.setId(pk2); pk2.setIdUser(u.getIdUser()); pk2.set... a2.set... u.addAddress(a2); entityManager.persist(u);

Hope this help you. Thanks

Hi,
I have a problem when persist an entity with its childs in OneToMany relationship. Here my two entity:
@Entity @Table(name="USER") public class User implements Serializable { ... @Id @Column(name="ID_USER") private String idUser; @OneToMany(mappedBy="user", cascade=CascadeType.PERSIST) private List<Address> address; public List<Address> getAddress() { return this.address; } public void setAddress(List<Address> address) { this.address = address; } public Address addAddress(Address address) { getAddress().add(address); address.setUser(this); return address; } public Address removeAddress(Address address) { getAddress().remove(address); address.setUser(null); return address; } ... } @Entity @Table(name="ADDRESS") public class Address implements Serializable { ... @EmbeddedId private AddressPK id; @ManyToOne(cascade = CascadeType.PERSIST) @JoinColumn(name="ID_USER", insertable=false, updatable=false, nullable=false) private User user; public User getUser() { return this.user; } public void setUser(User user) { this.user = user; } } @Embeddable public class AddressPK implements Serializable { ... @Column(name="ID_USER", insertable=false, updatable=false) private String idUser; ... }

And now the persist operation that generate ORA-02291 error:

User u = new User(); u.setAddress(new ArrayList<Address>()); u.set... Address a1 = new Address(); a1.set... u.addAddress(a1); Address a2 = new Address(); a2.set... u.addAddress(a2); entityManager.persist(u);

What can i do to fix the problem?

Thanks to everyone!

Hi everybody,
I'm using JBoss 7 for my webapp and I have several problem using ojdbc7 as jboss module. Here my configuration:

---module.xml---
<module xmlns="urn:jboss:module:1.0" name="com.oracle.jdbc"> <resources> <resource-root path="ojdbc7.jar"/> </resources> <dependencies> <module name="javax.api"/> <module name="javax.transaction.api"/> </dependencies> </module>

---standalone.xml---
... <datasource jta="true" jndi-name="java:jboss/datasources/ds" pool-name="ds" enabled="true" use-java-context="true" use-ccm="true"> <connection-url>jdbc:oracle:oci:@db</connection-url> <driver>OracleJDBCDriver</driver> <security> <user-name>user</user-name> <password>psw</password> </security> </datasource> <drivers> <driver name="OracleJDBCDriver" module="com.oracle.jdbc"> <xa-datasource-class>oracle.jdbc.driver.OracleDriver</xa-datasource-class> </driver> </drivers> ...

In my Java class, I want to instantiate OracleOCIConnectionPool because i want to connect to oracle db with different settings respect to those defining in standalone.xml (i have two different users that access to db).
When I try to use OracleOCIConnectionPool in my webapp, I have the following error:


16:29:16,309 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/web]] (MSC service thread 1-8) Exception sending context initialized event to listener instance of class com.test.Listener: java.lang.UnsatisfiedLinkError: Native Library C:\app\client\mypc\12.1.0\dbhome_1\bin\ocijdbc12.dll already loaded in another classloader at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1931) [rt.jar:1.7.0_76] at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1890) [rt.jar:1.7.0_76] at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1880) [rt.jar:1.7.0_76] at java.lang.Runtime.loadLibrary0(Runtime.java:849) [rt.jar:1.7.0_76] at java.lang.System.loadLibrary(System.java:1088) [rt.jar:1.7.0_76] at oracle.jdbc.driver.T2CConnection$1.run(T2CConnection.java:4123) [ojdbc7.jar:12.1.0.2.0] at java.security.AccessController.doPrivileged(Native Method) [rt.jar:1.7.0_76] at oracle.jdbc.driver.T2CConnection.loadNativeLibrary(T2CConnection.java:4119) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.driver.T2CConnection.logon(T2CConnection.java:312) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.driver.PhysicalConnection.connect(PhysicalConnection.java:666) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.driver.T2CDriverExtension.getConnection(T2CDriverExtension.java:54) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:573) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.pool.OracleOCIConnectionPool.createConnectionPool(OracleOCIConnectionPool.java:990) [ojdbc7.jar:12.1.0.2.0] at oracle.jdbc.pool.OracleOCIConnectionPool.setPoolConfig(OracleOCIConnectionPool.java:549) [ojdbc7.jar:12.1.0.2.0] at com.test.load.DSDb.<init>(DSDb.java:118) [ejb-0.0.1-SNAPSHOT.jar:] at com.test.load.DSDb.crea(DSDb.java:211) [ejb-0.0.1-SNAPSHOT.jar:] ....

I don't know why. Can someone help me, please?

Yes, is an apache timeout problem. Thank you! ;)

Hi,
for my web application I use Weblogic 10.3.5, Jpa 2.0 and Spring 3.1.
When I execute a search feature a strange thing happens: controller calls back-end side and java routine start (jpa db connection for get results and then java operation). Every one minute (I see this in front end and back end log file) the same functionality restart until Weblogin session (720 seconds) expires (operation during in total about 1 minute ad 30 seconds) . It seems as if there is a timeout of one minute. I have analyzed the status of the request with firebug and it seems that only one request start...but in the log file I see several started of the same functionality.

Can anyone help me?
