Struts2 align check box vertical

Normally the struts checkboxlist in struts2 diaply the check boxes horizontally. In most of application we want to
display the check boxes vetrically ie line by line. For aligning this as vertical we have to do as specified below
1) You have to create a directory template in your src folder
2) create a folder with name of the template you want to create (vertical-checkbox)
3) copy the struts-2.1.6/src/core/src/main/resources/template/simple/checkboxlist.ftl file to this directory content of this file is as follows. Before the </@s.iterator> you have to put a <br> tag as I given in this

<#assign itemCount = itemCount + 1/>
<#if parameters.listKey??>
<#assign itemKey = stack.findValue(parameters.listKey)/>
<#else>
<#assign itemKey = stack.findValue('top')/>

<#assign itemKeyStr=itemKey.toString() />
<input type="checkbox" name="${parameters.name?html}" value="${itemKeyStr?html}" id="${parameters.name?html}-${itemCount}"<#rt/>
<#if tag.contains(parameters.nameValue, itemKey)>
checked="checked"<#rt/>
</#if>
<#if parameters.disabled?default(false)>
disabled="disabled"<#rt/>
</#if>
<#if parameters.title??>
title="${parameters.title?html}"<#rt/>
</#if>
<#include "/${parameters.templateDir}/simple/scripting-events.ftl" />
<#include "/${parameters.templateDir}/simple/common-attributes.ftl" />
/>
<label for="${parameters.name?html}-${itemCount}" class="checkboxLabel">${itemValue?html}</label>
<br>
</@s.iterator>
<#else>

</#if>

4) <s:checkboxlist list="urlist" name="selectedValues" listKey="id" listValue="descrption" theme="vertical-checkbox"></s:checkboxlist>
this will give you vertical check box list
only difference is that here you have to specify the theme which is same as the directory u have created in the template directory in the src folder of your project

File Upload Struts2

This is a sample program to upload a file and save to databse using hibernate
fileupload.java contains a file field and a submit button
fileupload.jsp
<%@ taglib prefix="s" uri="/struts-tags"%>
<s:form action="addDocument" enctype="multipart/form-data" method="POST">
<table>
<tr>
<td><s:file label="File" name="data"></s:file></td>
</tr>
<tr>
<s:submit type="submit" theme="simple" value="Upload" />
</tr>
</table>
<s:form>

DocumentAction.java
package in.codeglobe.fileupload.action;
public class DocumentAction extends ActionSupport {
private File data;
private String dataContentType;
private String dataFileName;
private Document document = new Document();

public Document getDocument() {
return document;
}


public void setDocument(Document document) {
this.document = document;
}

public File getData() {
return data;
}


public void setData(File data) {
this.data = data;
}


public String getDataContentType() {
return dataContentType;
}


public void setDataContentType(String dataContentType) {
this.dataContentType = dataContentType;
}


public String getDataFileName() {
return dataFileName;
}


public void setDataFileName(String dataFileName) {
this.dataFileName = dataFileName;
}

public String add() {
String result = "view";
try {
FileInputStream fis;
byte[] content = null;
try {
fis = new FileInputStream(data);
content = new byte[fis.available()];
fis.read(content);
fis.close();
} catch (Exception e) {
throw e;
}
document.setData(content);
document.setFileName(dataFileName);
document.setContentType(dataContentType);
/*
u have to write the code to save in to the database
*/
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}
The addDocument action in the fileupload.jsp invokes the add method in the DocumentAction class
this method reads the datafrom the uploaded file and store it to the byte array in the
document class.

this is the action mapping for the upload file after successful upload page is redirected to success.jsp
struts.xml
<action name="*Document" method="{1}"
class="in.codeglobe.fileupload.action.DocumentAction">
<result name="view">/success.jsp</result>
</action>

Document.java
package in.codeglobe.fileupload.entity;
public class Document {

private Long documentId;
private String fileName;
private String contentType;
private byte[] data;

public Document() {

}

public String getFileName() {
return fileName;
}

public void setFileName(String fileName) {
this.fileName = fileName;
}



public String getContentType() {
return contentType;
}



public void setContentType(String contentType) {
this.contentType = contentType;
}



public byte[] getData() {
return data;
}



public void setData(byte[] data) {
this.data = data;
}



public Long getDocumentId() {
return documentId;
}


public void setDocumentId(Long documentId) {
this.documentId = documentId;
}
}




success,jsp
File with file name ${dataFileName} is successfully uploaded to database
File type: ${dataContentType}

This is the hibernate configuration
document.hbm.xml
