    }

    public void setInactive(String inactive) {

}

Maven + Hibernate + Select & Result List()

Session session = HibernateUtil.getSessionFactory().openSession();
            session.beginTransaction();
            Query q = session.createQuery(hql);
            List resultList = q.list();
            displayResult(resultList);
            session.getTransaction().commit();

private void displayResult(List resultList) {
        Vector<String> tableHeaders = new Vector<String>();
        Vector tableData = new Vector();
        tableHeaders.add("Id");
        tableHeaders.add("Category Name");
        tableHeaders.add("Status");
        tableHeaders.add("LastUpdate Date");

        for (Object o : resultList) {
            InvDclStockCategory Cat = (InvDclStockCategory) o;
            Vector<Object> oneRow = new Vector<Object>();
            oneRow.add(Cat.getId());
            oneRow.add(Cat.getDescription());
            oneRow.add(Cat.getInactive());
            oneRow.add(Cat.getLastUpdateDate());

            tableData.add(oneRow);
        }
        resultTable.setModel(new DefaultTableModel(tableData, tableHeaders));

    }

Maven + Hibernate Session Delete

Session session = HibernateUtil.getSessionFactory().openSession();
            session.beginTransaction();

                Student userAdd = (Student)session.get(Student.class, Id);

                session.delete(userAdd);
                session.getTransaction().commit();
                session.close();

Maven + Hibernate Session Update

      Session session = HibernateUtil.getSessionFactory().openSession();
          session.beginTransaction();
InvDclStockCategory cat = InvDclStockCategory)session.get(InvDclStockCategory.class, Id);

                cat.setDescription(Name);
                cat.setInactive(Status);

                session.update(cat);
                session.getTransaction().commit();
                session.close();

Maven + Hibernate Session Save

Session session = HibernateUtil.getSessionFactory().openSession();
          session.beginTransaction();

                InvDclStockCategory cat = new InvDclStockCategory();

                cat.setDescription(Name);
                cat.setInactive(Status);
                session.save(cat);
                session.getTransaction().commit();
                session.close();

Maven + Hibernate Mappings + Auto Increment Sequence Uses

<hibernate-mapping>
    <class name="com.datacraft.mavenproject1.InvDclStockCategory" table="inv_dcl_stock_category" schema="public">
        <id name="id" type="int">
            <column name="id" />

             <generator class="sequence">
                 <param name="sequence">inv_dcl_stock_category_id_seq</param>
             </generator>

        </id>
        <property name="description" type="string">
            <column name="description" length="255" />
        </property>

        <property name="inactive" type="string">
            <column name="inactive" />
        </property>
        <property name="creatDate" type="date">
            <column name="create_date" length="13" />
        </property>
        <property name="lastUpdateDate" type="date">
            <column name="last_update_date" length="13" />
        </property>
    </class>

Java Regular Expressions common matching symbols

Regular Expression Description Example

. Matches any single character (“..”, “a%”) – true(“..”, “.a”) – true

(“..”, “a”) – false

^xxx Matches xxx regex at the beginning of the line (“^a.c.”, “abcd”) – true

(“^a”, “ac”) – false

xxx$ Matches regex xxx at the end of the line (“..cd$”, “abcd”) – true(“a$”, “a”) – true

(“a$”, “aca”) – false

[abc] Can match any of the letter a, b or c. [] are known as character classes.

(“^[abc]d.”, “ad9″) – true(“[ab].d$”, “bad”) – true

(“[ab]x”, “cx”) – false

[abc][12] Can match a, b or c followed by 1 or 2

(“[ab][12].”, “a2#”) – true(“[ab]..[12]“, “acd2″) – true

(“[ab][12]“, “c2″) – false

[^abc] When ^ is the first character in [], it negates the pattern,

matches anything except a, b or c

(“[^ab][^12].”, “c3#”) – true(“[^ab]..[^12]“, “xcd3″) – true

(“[^ab][^12]“, “c2″) – false

[a-e1-8] Matches ranges between a to e or 1 to 8

(“[a-e1-3].”, “d#”) – true(“[a-e1-3]“, “2″) – true

(“[a-e1-3]“, “f2″) – false

xx|yy Matches regex xx or yy (“x.|y”, “xa”) – true(“x.|y”, “y”) – true

(“x.|y”, “yz”) – false
