• FreeMarker is a template engine; a generic tool to generate text output

To Print the Values in FTL
Welcome ${user}

If condition in FTL
<#if field.formatType??>
</#if>


Loops in FTL
<#list tabList as page>
</#list>

• Creating Own Components Using FTL
Eg. Creating Password Field Using FTL

<input type="password" <#rt/>
 name="${parameters.name?default("")?html}"<#rt/>
 
<#if parameters.get("size")??>
 size="${parameters.get("size")?html}"<#rt/>
</#if>

<#if parameters.maxlength??>
 maxlength="${parameters.maxlength?html}"<#rt/>
</#if>

<#if parameters.id??>
 id="${parameters.id?html}"<#rt/>
</#if*gt;

<#if parameters.get("size")??>
 size="${parameters.get("size")?html}"<#rt/>
</#if>


<#if parameters.onblur??>
 onblur="${parameters.onblur?html}"<#rt/>
</#if>
/>

NOTE : Store your FTL File in public-html template finnonepro

• Calling FTL using <s:component tag> , place in JSP File

<s:component template="password.ftl" theme="finnonepro"
 id="28000005" name="FW_SC_PW_OodPW">
<s:param name="maxlength" value="'20'"/>
    <s:param name="size" value="'12'"/>
  <s:param name="mandatory" value="'Y'"/>
</s:component>

• IOC and DI are programming design patterns, which are used to reduce coupling in programming.
• It follow the Following Principle:
• You do not need to create your objects.
• You need to only describe how they should be created. (This think is done by ObjectFactory)

To enable the IOC in Struts

package com.nuc.actions;
import com.opensympony.xwrok2.ActionContext;
import com.opensympony.xwrok2.ActionSupport;
import java.util.Map;
import org.apache.struts.interceptor.SessionAware;
public classLoginAction extends ActionSupport implements SessionAware{

	private String userid;
	private String password;
	private Map<String,Object> _session;
	public LoginAction(){
		super();
	}
	public String checkLogin(){
		String action="error";
		if(this.getUserid().equalsIgnoreCase(this.getPassword())){
		_session.put("userid",getUserid());
			action="success";
		}
		return action;
	}
	public void setUserid(String userid){
	this.userid=userid;
	}
	public String getUserid(){
	return userid;
	}
	public void setPassword(String password){
	this.password=password;
	}
	public String getPassword(){
	return password;
	}
	public void setSession(Map<String,Object> map){
	this._session=map;
	}
	public Map<String,Object> getSession(){
	return _session;
	}
}
