So what if custom HTML attributes aren't valid XHTML?

- by Constantine

I know that is the reason some people don't approve of them, but does it really matter? I think that the power that they provide, in interacting with JavaScript and storing and sending information from and to the server, outweighs the validation concern. Am I missing something? What are the ramifications of "invalid" HTML? And wouldn't a custom DTD resolve them anyway?

How do I set up a .emacs initialization file? [migrated]

- by Harry Weston

I am using Linux Fedora 13 (Constantine) and emacs 23.1.1. I am trying to set up a .emacs file for initialization, by using emacs itself to edit and save a file .emacs in my home directory. However, although the file is there, emacs does not seem to recognize it. What might I be doing wrong, and is there a simple text for .emacs that will show me if it is being used, one that will display a message on emacs start up?

OTN Architect Day - Boston - Sept 12: What to Expect If you've never attended an OTN Architect Day, here's a little preview. You start with a continental breakfast. Then you have keynotes by an Oracle expert, and a member of the Oracle ACE community. After that come the break-out sessions, so you have your choice of two sessions in each time slot. So you'll get in two breakouts before lunch. Then you eat. After that there's a panel Q&A during which the audience tosses questions at the assembled session speakers. Then it's on to another set of break-out sessions, followed by a short break. Then the audience breaks into small groups for round table discussions. After that there's a drawing for some cool prizes, followed by the cocktail reception. All that costs you absolutely zero. Register now. Starting and Stopping Fusion Applications the Right Way | Ronaldo Viscuso While the fastartstop tool that ships with Oracle Fusion Applications does most of the work to start/stop/bounce the Fusion Apps environment, it does not do it all. Oracle Fusion Applications A-Team blogger Ronaldo Viscuso's post "aims to explain all tasks involved in starting and stopping a Fusion Apps environment completely." Dodeca Customer Feedback - The Rosewood Company | Tim Tow Oracle ACE Director Tim Tow shares anecdotal comments from one of his clients, a company that is deploying Dodeca to replace an aging VBA/Essbase application. Configuring UCM cache to check for external Content Server changes | Martin Deh Oracle WebCenter and ADF A-Team blogger Martin Deh shares the background information and the solution to a recently encountered customer scenario. Proxy As Upgrade to 11g Does Not Like NQSession.User | Art of Business Intelligence "In Oracle BI 10g the application was a lot more tolerant of bad design and cavalier usage of variables," observes Oracle ACE Christian Screen. "We noticed an issue recently during an upgrade where the Proxy As configuration in Oracle BI 10g used the NQSession.User variable to identify the user logged into Presentation Servers acting as Proxy." Oracle WebLogic Server 11g: Interactive Quick Reference | Dirk Nachbar Oracle ACE Dirk Nachbar shares a quick post with information on a new interactive reference guide to Oracle WebLogic Server. "The Quick Reference shows you an architecural overview of the Oracle WebLogic Server processes, tools, configuration files, log files and so on including a short description of each section and the corresponding link to the Oracle WebLogic Server Documentation," says Nachbar. Thought for the Day "In fast moving markets, adaptation is significantly more important than optimization." — Larry Constantine Source: Quotes for Software Engineers

PostgreSQL, Ubuntu, NetBeans IDE (Part 3)

- by Geertjan

To complete the picture, let's use the traditional (that is, old) Hibernate mechanism, i.e., via XML files, rather than via the annotations shown yesterday. It's definitely trickier, with many more places where typos can occur, but that's why it's the old mechanism. I do not recommend this approach. I recommend the approach shown yesterday. The other players in this scenario include PostgreSQL, as outlined in the previous blog entries in this series. Here's the structure of the module, replacing the code shown yesterday: Here's the Employee class, notice that it has no annotations: import java.io.Serializable; import java.util.Date; public class Employees implements Serializable { private int employeeId; private String firstName; private String lastName; private Date dateOfBirth; private String phoneNumber; private String junk; public int getEmployeeId() { return employeeId; } public void setEmployeeId(int employeeId) { this.employeeId = employeeId; } 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 Date getDateOfBirth() { return dateOfBirth; } public void setDateOfBirth(Date dateOfBirth) { this.dateOfBirth = dateOfBirth; } public String getPhoneNumber() { return phoneNumber; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public String getJunk() { return junk; } public void setJunk(String junk) { this.junk = junk; } } And here's the Hibernate configuration file: <?xml version="1.0"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/smithdb</property> <property name="hibernate.connection.username">smith</property> <property name="hibernate.connection.password">smith</property> <property name="hibernate.connection.pool_size">1</property> <property name="hibernate.default_schema">public"</property> <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> <property name="hibernate.current_session_context_class">thread</property> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="hibernate.show_sql">true</property> <mapping resource="org/db/viewer/employees.hbm.xml"/> </session-factory> </hibernate-configuration> Next, the Hibernate mapping file: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="org.db.viewer.Employees" table="employees" schema="public" catalog="smithdb"> <id name="employeeId" column="employee_id" type="int"> <generator class="increment"/> </id> <property name="firstName" column="first_name" type="string" /> <property name="lastName" column="last_name" type="string" /> <property name="dateOfBirth" column="date_of_birth" type="date" /> <property name="phoneNumber" column="phone_number" type="string" /> <property name="junk" column="junk" type="string" /> </class> </hibernate-mapping> Then, the HibernateUtil file, for providing access to the Hibernate SessionFactory: import java.net.URL; import org.hibernate.cfg.AnnotationConfiguration; import org.hibernate.SessionFactory; public class HibernateUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from standard (hibernate.cfg.xml) // config file. String res = "org/db/viewer/employees.cfg.xml"; URL myURL = Thread.currentThread().getContextClassLoader().getResource(res); sessionFactory = new AnnotationConfiguration().configure(myURL).buildSessionFactory(); } catch (Throwable ex) { // Log the exception. System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } Finally, the "createKeys" in the ChildFactory: @Override protected boolean createKeys(List list) { Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction transac = null; try { transac = session.beginTransaction(); Query query = session.createQuery("from Employees"); list.addAll(query.list()); } catch (HibernateException he) { Exceptions.printStackTrace(he); if (transac != null){ transac.rollback(); } } finally { session.close(); } return true; } Note that Constantine Drabo has a similar article here. Run the application and the result should be the same as yesterday.
