A phpBB Forum Clone in JSF
Einführung: Hi dies ist die README zum JSF-Forum. Es ist ein phpbb Clone in JSF, also auf Basis von Java Enterprise. Dieses Projekt wurde ins Leben gerufen, da ich lange zeit mit dem JForum gearbeitet habe und auch selbst einige änderungen dran gemacht habe. Das JForum ist leider schon sehr alt und nicht mehr zeitgemäß. Es ist zeit für etwas neues.....lasst uns also starten Installation und Einrichtung: Ihr braucht folgende Programme: - Netbeans (wird empfohlen) oder Eclipse (mit JEE Plugins) - Glassfish (zurzeit 3.0.1) - Mysql DB mit einer neuen Datenbank so nun könnt ihr fast schon starten. Es fehlt allerdings noch eine eigene persistence.xml mit den Daten zu eurer DB diese könnt ihr zumindest in Netbeans sehr einfach erstellen Herzlichen Glückwunsch ihr seit startbereit. nachdem ihr nun das Forum in eure IDE importiert habt und der Glassfish gestartet ist. Könnt ihr nun das Forum schonmal ein wenig mit Daten befüllen dies geschieht, in dem ihr z.b. localhost:8080/JSF-Forum-war/faces/install.xhtml aufruft und den Button drückt, dadurch werden ein paar Foren,Categories usw. angelegt. Nun seit ihr startbereit zur Entwicklung.
I devised a sample category with subcategory module in jsf by eclipse. I made an adding category module without any issue but I couldn't make an adding subcategory under related category . Here the code below.
Suncategory .xhtml
<h:form>
<p:panelGrid columns="2">
<h:outputLabel value="Category Name></h:outputLabel>
<p:selectOneMenu value="#{subCategoryMB.categoryName}">
<f:selectItem itemLabel="Select Category" itemValue=""></f:selectItem>
<f:selectItems value="#{subCategoryMB.categorylist}" />
</p:selectOneMenu>
<h:outputLabel value="Category Name"></h:outputLabel>
<p:inputText value="#{subCategoryMB.subcategory.subName}"></p:inputText>
<h:outputLabel value="Category Description"></h:outputLabel>
<p:inputText value="#{subCategoryMB.subcategory.subNameDes}"></p:inputText>
<h:commandButton value="Add Subcategory" action="#{subCategoryMB.addSubCategory()}"></h:commandButton>
</p:panelGrid>
/h:form
</h:body
Category Dao
public List getAllcategoriesbyName(String name) {
// TODO Auto-generated method stub
Session session = HibernateUtil.getSessionFactory().openSession();
try {
List<Category> liste = session.createQuery("from Category C where name='"+name+"'").list();
return liste;
} catch (Exception e) {
e.printStackTrace();
}finally {
session.close();
}
return null;
}
public List getAllcategoriesSelectItemName() {
// TODO Auto-generated method stub
Session session = HibernateUtil.getSessionFactory().openSession();
try {
List<Category> liste = session.createQuery("Select C.name from Category C").list();
return liste;
} catch (Exception e) {
e.printStackTrace();
}finally {
session.close();
}
return null;
}
SubCategoryMB
public class SubCategoryMB {
SubCategory subcategory = new SubCategory();
private String categoryName;
private List categorylist;
private List subCategoryList;
private Category category= new Category();
public SubCategoryMB() {
// TODO Auto-generated constructor stub
}
public SubCategory getSubcategory() {
return subcategory;
}
public void setSubcategory(SubCategory subcategory) {
this.subcategory = subcategory;
}
public List getCategorylist() {
CategoryDAO cDao = new CategoryDAO();
this.categorylist= cDao.getAllcategoriesSelectItemName();
return categorylist;
}
public void setCategorylist(List categorylist) {
this.categorylist = categorylist;
}
public String getCategoryName() {
return categoryName;
}
public void setCategoryName(String categoryName) {
this.categoryName = categoryName;
}
public Category getCategory() {
return category;
}
public void setCategory(Category category) {
this.category = category;
}
public List getSubCategoryList() {
SubCategoryDAO subDao = new SubCategoryDAO();
this.subCategoryList= subDao.getAllSubcategories();
return subCategoryList;
}
public void addSubCategory(){
// ISSUE
categorylistbySubCategory= new CategoryDAO().getAllcategoriesbyName(categoryName);
category.setId(categorylistbySubCategory.get(0).getId());
subcategory.setCategory(category);
subcategory.setSubName(subcategory.getSubName());
subcategory.setSubNameDes(subcategory.getSubNameDes());
new SubCategoryDAO().addSubCategory(subcategory);
}
}
There is a problem about addSubCategory(). I can't add subcategory to its category.
