Dynamically generate JSF Source code in a JSP

Question

Hi,
I have a JSP and instead of writing the JSF source Code like:
<h:inputText
styleClass="entryInput"
id="textNumberOfServerMachinesInput"
value="#{DataAccess.value}"
valueChangeListener="#{InputValueChanged.processValueChange}">
</h:inputText>
manually in the jsp I want the JSF source code to be added dynamically to the jsp.
So what I want is including a tag in the jsp and this tag generates JSF source code like seen above.
This source code should then be treated just the way it would be if I had written it manually in the JSP. This means that the dynamically generated JSF code must be interpreted and all Listeners and Beans work just fine.
How can I make this???

Hi,
I have a smiliar problem:
JSP:
<h:panelGrid binding="#{fileUploadGrid.panelGrid}">
   <%-- emty in jsp --%>
</h:panelGrid>The panel should be populated with items the backing bean creates in source code:
FileUploadGrid.java
public void setUploadFieldNumber(int uploadFieldNumber) {
    this.uploadFieldNumber = uploadFieldNumber;
    this.refresh();
private void refresh() {
    if (this.panelGrid == null)
      this.createPanelGrid();
    List children = this.panelGrid.getChildren();
    children.clear();
    for (int i = 0; i < this.uploadFieldNumber; i++) {
      HtmlOutputText out = new HtmlOutputText();
      out.setTitle("Image " + i);
      out.setRendered(true);
      HtmlInputText in = new HtmlInputText();
      children.add(out);
      children.add(in);   
private void createPanelGrid() {
    this.panelGrid = new HtmlPanelGrid();
    this.panelGrid.setColumns(2);
    this.panelGrid.setCellpadding("1");
    this.panelGrid.setBorder(1);
    this.panelGrid.setWidth("50%");
    this.panelGrid.setRendered(this.isRendered());
public void setPanelGrid(HtmlPanelGrid panelGrid) {
    this.panelGrid = panelGrid;
  public HtmlPanelGrid getPanelGrid() {
    return this.panelGrid;
}The backing bean is initialized in faces-config.xml:
<managed-bean>
  <managed-bean-name>fileUploadGrid</managed-bean-name>
  <managed-bean-class>org.smi.pte.isf.FileUploadGrid</managed-bean-class>
  <managed-bean-scope>request</managed-bean-scope>
  <managed-property>
    <property-name>rendered</property-name>
    <value>true</value>
  </managed-property>
  <managed-property>
     <property-name>uploadFieldNumber</property-name>
     <value>6</value>
  </managed-property>
</managed-bean>The problem is: although the debug output of the faces framework (I use it along with Tomcat) shows that the in- and output fields are added correctly to the panel, the page remains empty at display.
Thanks in advance for any help.
