Connecting to hibernate
Hi
My web application is a JSF application and it uses hibernate (ORM) to hide DB details from the webdeveloper , so he directly works with POJOs.
I know that CR4E enables me to work with POJOs , so my questions are:
1- How can i work with POJOs using PUSH method ? (note : i'm using JSP pages under JSF framework)
2- Can i work with POJOs using the PULL method (so i don't prepare any objects in advance and let the report ask for them "somehow" ) ?
3- is it possible to use HQL (hibernate query language) instead of SQL in the reports.
4- in the PUSH or PULL method , i want the DB querying to be on demand when the user navigate to the pages , as there are scenarios where the report should contain man results , but the user will just see the first page and will close the report , so i don't want the report to load all the data from the database at the start up , i want it to load the data of the first page only , and the rest will be on demand.
Thanks ,
Joseph

ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:XE, "system", "mypass50";what do you think the SID is in the URL you provided?
<property name="connection.url">
jdbc:oracle:thin:@localhost:1521:XE, "system", "mypass50";
</property> ...
And what do you think it should be?

Trouble connecting to MySQL database with Hibernate
I'm using red hat studio pro. I created an hibernate.cfg.xml file with
the hibernate tools.
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="hibernate.connection.driver_jar">mysql-connector-
java-5.0.6-bin.jar</property>
<property
name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</
property>
<property name="hibernate.connection.password"> </property>
<property name="hibernate.connection.url">jdbc:mysql://
localhost/eshop</property>
<property name="hibernate.connection.username">user</property>
<property
name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</
property>
</session-factory>
</hibernate-configuration>
Reverse Engineering was no problem, it found the database, could read
the tables and create the java classes.
Now I tried to open a simple connection to the database and that
doesn*t work. I always get a "no suitable driver found" error.
Code:
Configuration config = new Configuration()
.setProperty("hibernate.dialect",
"org.hibernate.dialect.MySQLInnoDBDialect")
.setProperty("hibernate.connection.driver_class",
"org.gjt.mm.mysql.Driver")
.setProperty("hibernate.connection.driver_jar", "mysql-connector-
java-5.0.6-bin.jar")
.setProperty("hibernate.connection.password", " ")
.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:
3306/eshop")
.setProperty("hibernate.connection.username", "user")
.addClass(Adressen.class);
config.configure();
SessionFactory sessionFactory = config.buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
System.out.println("works");
} catch (Exception e) {
if (tx != null) {
tx.rollback();
System.out.println("error - rollback");
} finally {
session.close();
sessionFactory.close();
The errors I'm getting are:

Can anybody tell me, what I'm doing wrong?ClassNotFoundException means the driver isn't loaded. "No suitable driver" usually tells me that the syntax in the connection URL is incorrect for some reason.
Make sure you have an up to date driver JAR:

The driver class name should be com.mysql.jdbc.Driver

Spring-Webflow Authentication and Hibernate
Does anyone have experience authenticating against Oracle using Spring 2.5, Spring-Webflow, Hibernate 3.3? Then using the authenticated credentials to create a proxy authenticated connection for hibernate?

Hello everyone, sorry someone knows how can I use hibernate on the layer model, and ADF in the presentation layer?
I have made my connection to hibernate and I have also designed my page with ADF, and to unite both layers I created a "Data Control" but they do not work for me. I get the following error:
java.lang.OutOfMemoryError: PermGen space
sun.misc.Unsafe.defineClass at (Native Method)
at sun.reflect.ClassDefiner.defineClass (ClassDefiner.java: 45)

at java.security.AccessController.doPrivileged (Native Method)
at sun.reflect.MethodAccessorGenerator.generate (MethodAccessorGenerator.java: 377)
Truncated. see log file for complete Stacktrace
I think the error is when direcceciono in your hibernate file "hibernate.cfg.xml" because I write everything from what direction the unit c. I do this because when I write I do not routed to the directory where JDeveloper is installed.
Agradesco them in advance for your kind responses.Hi Jhon, thanks for your help, and I get no error.

I want to use hibernate with the tomcat
I want to use hibernate with the tomcat server can it be possible and if yes then what is the stepwise way.
Infact I know the java JSF but want to command on Hibernate plz help me.
I'll be thankful to you.To be honest, I wouldn't even know where to start. Do you know what Hibernate does and how it works? Do you know how Tomcat works? All you'd need to do to combine those two would be to let Tomcat provide the DB connections for Hibernate, I suppose. Neither of those products are a topic of this board though.

Losing connection to db with many users
Hi all,
I'm using tomcat 6 + mysql + c3p0 connection pools + hibernate.
If i test my web application with Apache JMeter simulating 100 users (threads?!) in a page, after 5-30 seconds i will lose the connection to db.
If I redeploy the application it work again... In the tomcat manager I see 15'000/18'000 sessions :S
Please help me and sorry for my bad englishPlease have a bit more patience. I can't imagine that this topic was already out of the sight of the active topic listing after 5 hours.

今天花了一些时间写了一篇文章<<手把手配置Hibernate环境>>,里面包括一整套基本的Hibernate开发流程,从最简单的开始,我觉得这篇文章对初学者很有用,所以好东西当然少不了大家的,贴上来和大家一起分享,呵呵.
手把手配置Hibernate环境(JBuilderX版)
作者:bluesky35(蓝天)
开发环境: Windows2000 + JBuilderX + Hibernate2.1.6 + Oracle9i
1.安装JBuilderX和Oracle9i,并使用以下信息配置Oracle
用户名:system
密码:admin
服务:cpdb
2.先去http://prodownloads.sourceforge.net/hibernate/下载Hibernate API的包hibernate-2.1.6.zip
3.在JBuilder中选择Project菜单中的Project Properties,在Require Library中加入Hibernate所有的API包,还要加入Oracle目录ORANT\jdbc\lib\classes12.zip
4.然后将截压缩后的hibernate-2.1\etc\hibernate.properties拷贝到本地project的classes目录下然后做以下变化:
①注释默认的数据库连接,将
## HypersonicSQL
hibernate.dialect net.sf.hibernate.dialect.HSQLDialect
hibernate.connection.driver_class org.hsqldb.jdbcDriver
hibernate.connection.username sa
hibernate.connection.password
hibernate.connection.url jdbc:hsqldb:hsql://localhost
hibernate.connection.url jdbc:hsqldb:test
hibernate.connection.url jdbc:hsqldb:.
改为
## HypersonicSQL
#hibernate.dialect net.sf.hibernate.dialect.HSQLDialect
#hibernate.connection.driver_class org.hsqldb.jdbcDriver
#hibernate.connection.username sa
#hibernate.connection.password
#hibernate.connection.url jdbc:hsqldb:hsql://localhost
#hibernate.connection.url jdbc:hsqldb:test
#hibernate.connection.url jdbc:hsqldb:.
然后修改Oracle的连接,将
## Oracle
#hibernate.dialect net.sf.hibernate.dialect.Oracle9Dialect
#hibernate.dialect net.sf.hibernate.dialect.OracleDialect
#hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
#hibernate.connection.username ora
#hibernate.connection.password ora
#hibernate.connection.url jdbc:oracle:thin:@localhost:1521:test
改为
## Oracle
hibernate.dialect net.sf.hibernate.dialect.Oracle9Dialect
hibernate.dialect net.sf.hibernate.dialect.OracleDialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.username system
hibernate.connection.password admin
hibernate.connection.url jdbc:oracle:thin:@172.28.122.49:1521:cpdb
注意:@172.28.122.49为Oracle服务器的ip地址,1521为端口号
5.在project下建立package person,在package下建立四个class,分别为:
①PersonModel.java
package person;
import java.io.Serializable;
public class PersonModel implements Serializable {
private Long id;
private String name;
private String address;
public Long getId() {
return id;
public void setId(Long id) {
this.id = id;
public void setName(String name) {
this.name = name;
public String getName() {
return name;
public void setAddress(String address) {
this.address = address;
public String getAddress() {
return address;
②TestPersonModel1.java
package person;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
import net.sf.hibernate.tool.hbm2ddl.SchemaExport;
public class TestPersonModel1 {
private static SessionFactory sessionFactory;
public static void main(String[] args) throws Exception{
System.out.println("start");
Configuration conf= new Configuration().addClass(PersonModel.class);
SchemaExport dbExport=new SchemaExport(conf);
dbExport.setOutputFile("sql_out_lib\\sql.txt");
dbExport.create(true, true);
③TestPersonModel2.java
package person;
import net.sf.hibernate.Session;
import net.sf.hibernate.Transaction;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
public class TestPersonModel2 {
private static SessionFactory sessionFactory;
public static void main(String[] args) throws Exception{
Configuration conf= new Configuration().addClass(PersonModel.class);
//在表中插入第一条数据
sessionFactory = conf.buildSessionFactory();
Session s = sessionFactory.openSession();
Transaction t = s.beginTransaction();
PersonModel p1=new PersonModel();
p1.setName("zhaol");
p1.setAddress("shanghai");
//持久化
s.save(p1);
//数据库中已有记录
t.commit();
s.close();
④TestPersonModel3.java
package person;
import net.sf.hibernate.Session;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
import net.sf.hibernate.Query;
public class TestPersonModel3 {
private static SessionFactory sessionFactory;
public static void main(String[] args) throws Exception{
Configuration conf= new Configuration().addClass(PersonModel.class);
sessionFactory = conf.buildSessionFactory();
Session s = sessionFactory.openSession();
PersonModel p = new PersonModel();
Query q = s.createQuery("from PersonModel as p where p.id=1");
p = (PersonModel) q.list().get(0);
System.out.println(p.getName());
s.close();
其中PersonModel.java是对应数据库中字段的存储结构,TestPersonModel1.java是测试自动创建表和字段,TestPersonModel2.java是测试在表中插入记录,TestPersonModel3.java是测试从表中取得记录.
6.编译所有的java文件
7.好了,到最后一步了,也是最关键的一步,我们已经定义了数据库连接(hibernate.properties)
创建了字段的存储结构(PersonModel.java),也写好了操作数据库的代码(TestPersonModel1.java～TestPersonModel3.java),接下来要做的是定义数据库中表的配置文件,因为我们的字段的存储结构文件是PersonModel.java,所以创建PersonModel.hbm.xml(注意:表的配置文件名是由[字段的存储结构文件名+.hbm.xml]构成,创建位置为project的class\person目录下(注意:数据库定义文件hibernate.properties是放在class目录下的,而表的配置文件要放在相对应的包下,我们这里的包名是person,所以就放在class\person下)
PersonModel.hbm.xml的内容如下:
<?xml version="1.0" encoding="GB2312"?>
<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >
<hibernate-mapping>
<class name="person.PersonModel"
table="zl">
<id name="id" type="long">
<generator class="sequence">
<param name="sequence">ZL_ID_SEQ</param>
</generator>
</id>
<property name="name"/>
<property name="address"/>
</class>
</hibernate-mapping>
表名为zl,里面有两个字段(name和address,对应person.PersonModel),id是一个sequence.
9.好了,配置完成,接下来运行一下吧,先运行TestPersonModel1.class,让hibernate为我们自动建立一张名为zl(内有字段name和address)的表
怎么样?表是不是已经建好了,呵呵.
接下来运行TestPersonModel2.class,让hibernate再为我们插入一条记录
hibernate环境的配置就讲到这里,如有疑问可以和我联系:),我的QQ是81806701.

Exception in thread "main"
-
Insert then update on same row in bean Transaction leads to deadlock
<b>Setup Details</b>
Hibernate version: 3.1.2
EJB version: 2.0
Name and version of the database : MS SQL Server 2000
Datasource implmentation class being used : com.sap.nwmss.jdbcx.sqlserver.SQLServerDataSource
We are using SAP NetWeaver Application Server 6.0 and Hibernate 3.1.2 in our application. We have StalessSessionBeans which use Hibernate to interact with the database. We are running into a situation where the application goes into a hang state when the following flow is bein executed:
//transaction attribute = "Required"
beanMethod() {
myObj = new MyObj();
myObj.setSomeValue();
session = SessionFactory.openSession();
//id is auto generated by database
id = session.insert(myObj);
//retrieve the recently inserted obj
myUpdatedObj = session.load(id);
//modify the myUpdatedObj
myUpdatedObj.modifySomeValue();
//update using hibernate session
session.update(myUpdatedObj);
//return from method
Here's the flow:
1) In a CMT stateless session bean, there's a method which has transaction atrribute as "Required"
2) This method creates a new object and inserts it
3) Then loads this saved object and modifies some values in it
4) Then invokes the update method on the session to update this modified object in the database.
Note: We have enabled auto flush on transaction in the hibernate configuration file.
And here's what we are observing:
- The insert obtains a lock on the row as part of the transaction
- When the update is called on the same row as part of the auto flush, the update never completes. The update statement is unable to obtain a lock on the same row.
Here is some additional info:
- We have set :
session.connection().setTransactionIsolation(Connection.TRANSACTION_READ_UNCOMMITTED);
hibernate.cfg.xml:
<?xml version="1.0" encoding="UTF-8"?>

Any clue why the update query is having problem in completing, even though update and insert are being called from the same bean method as part of a transaction?

Somewhere I red that was necessary to update the jdbc driver, so I updated it from version nro 2 to version nro 3.1.7 but still the error
Phpmyadmin works ok and mysql control center can connect ok too.
But when I try a telnet localhost:3306 I receive and error of connection filed
Anyway the mysql status thowme correct information, that it working ok!
Any idea ?

CC&B deployment error - SPLWeb
Hi ,
We are trying to deploy CC&B (2.3.0) on Weblogic 10 MP2 and Oracle 11.1.0.7 & Windows 2003 Server 32bit.
We are deploying the SPLWeb.ear and SPLServices.ear in Weblogic. The SPLServices.ear was successfully deployed , but SPLWeb.ear is failing to deploy due to error as below:
2010-04-14 10:17:40,186 [com.mchange.v2.async.ThreadPoolAsynchronousRunner$P
oolThread-#1] WARN (v2.resourcepool.BasicResourcePool) com.mchange.v2.resourcep

ng pending acquires. While trying to acquire a needed new resource, we failed to
succeed more than the maximum number of allowed acquisition attempts (30). Last

The hibernate.properties files in the CC&B environment as given below: - (The username / password is correct as below)
hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
hibernate.connection.url = jdbc:oracle:thin:@01HW157263:1521:CCNB

hibernate.cache.use_second_level_cache = false
hibernate.query.substitutions = true 'Y', false 'N'
## Use C3P0 connection pooling, just define the below
hibernate.connection.provider_class=org.hibernate.connection.C3P0ConnectionProvider
hibernate.c3p0.min_size = 1
hibernate.c3p0.max_size = 150
hibernate.c3p0.timeout = 300
hibernate.c3p0.max_statements = 0
#some other values seen elsewhere, might need tweaking
hibernate.c3p0.idle_test_period = 0
hibernate.c3p0.acquire_increment = 1
Please suggest how the problem can be solved.
Thanks and Regards
AntaraAccount was locked after 30 attempts (+FAILED_LOGIN_ATTEMPTS LIMIT on the PROFILE+) to establish a connection, probably you need to recheck the password supplied during user creation on the database for CISUSER.
Also passwords are case sensitive starting 11g, that too being optional; set by enabling/disabling case sensivity through SEC_CASE_SENSITIVE_LOGON initialization parameter. -
I've got a Seam app that needs to use a JNDI datasource file to connect to an Oracle 10g instance. I can create a connection manually in Eclipse and do a "Test Connection" successfully; however, I've not yet figured out how to get Eclipse to recognize the JNDI file with the identical credentials. Here's the persistence.xml file for the app:
<persistence-unit name="ora-forms" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/ora-forms</jta-data-source> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/> <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver"/> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/> <property name="jboss.entity.manager.factory.jndi.name" value="java:/ora-forms"/> </properties> </persistence-unit>
Here's the hibernate-console.properties:
hibernate.connection.password= hibernate.connection.username= hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver hibernate.dialect=org.hibernate.dialect.Oracle10gDialect hibernate.connection.url= hibernate.connection.provider_class=org.hibernate.connection.DriverManagerConnectionProvider hibernate.datasource=java:/ora-forms hibernate.transaction.manager_lookup_class=
When we try to use the "Seam Generate Entities" to read the database, it gives the following error:
Can't generate seam entities org.hibernate.exception.JDBCConnectionException: Getting database metadata Getting database metadata org.hibernate.exception.JDBCConnectionException: Getting database metadata Getting database metadata java.sql.SQLException: No suitable driver No suitable driverIs it easier to manage EJB's or servers using JMS and
JNDI technologies?I would read the j2ee tutorial or a good book on J2ee if I were you.
