Please, could anyone help me?

Check if you have common-lang.jar of version 2.3 (as written by your link here: http://displaytag.sourceforge.net/11/displaytag/dependencies.html) otherwise browse if the jar has this class. If there is no class org.apache.commons.lang.UnhandledException in this jar you should download recommended version (http://commons.apache.org/proper/commons-lang/).

File upload not working with Struts2 Model-Driven Interface

When I am using Model driven interface, my file upload operation is not working.
It is not popping any error, nor it is generating any log.
My code is attached hereby,
I want to know for file, do we have to generate its getters/setters in Model or Action with Model-Driven interface.
Atleast it should get uploaded to temp folder, as with struts by default uploads to temp.
Action
ProductAction.java
package com.fileupload.action;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.fileupload.model.FileUploadModel;
/**
* Action class to requests
* #package com.fileupload.action
*/
public class FileUploadAction extends ActionSupport implements ModelDriven<Object>{
FileUploadModel fileModel = new FileUploadModel();
#Override
public Object getModel() {
return fileModel;
}
}
Model ProductModel.java
package com.fileupload.model;
import java.io.File;
/**
* Model class to handle data
* #package com.fileupload.model
*/
public class FileUploadModel {
private String employeeName;
private File image;
private String imageFileName;
private String imageFileCotentType;
public File getImage() {
return image;
}
public void setImage(File image) {
this.image = image;
}
public String getImageFileName() {
return imageFileName;
}
public void setImageFileName(String imageFileName) {
this.imageFileName = imageFileName;
}
public String getImageFileCotentType() {
return imageFileCotentType;
}
public void setImageFileCotentType(String imageFileCotentType) {
this.imageFileCotentType = imageFileCotentType;
}
public String getEmployeeName() {
return employeeName;
}
public void setEmployeeName(String employeeName) {
this.employeeName = employeeName;
}
}

Of,course,your file upload operation can working When you using Model
driven interface but you made a few mistake:
public class FileUploadModel {
private String employeeName;
private File image;
private String imageFileName;
// YourCode was wrong : private String imageFileCotentType;
private String imageFileContentType;
(get set)...
And then,you need to add a piece of code to your code for upload like
this:
#Namespace("/")
#ParentPackage("struts-default")
public class FileUploadAction extends ActionSupport implements ModelDriven<FileUploadModel> {
private static final long serialVersionUID = 1L;
FileUploadModel fileModel = new FileUploadModel();
#Override
public FileUploadModel getModel() {
return fileModel;
}
#Action(value = "submitForm", results = {
#Result(name = "success", location = "/result.jsp") })
public String submitForm() {
HttpServletRequest request = ServletActionContext.getRequest();
String tomcatPath = ServletActionContext.getServletContext().getRealPath("/");
String projectName = request.getContextPath();
projectName = projectName.substring(1);
String filePath = tomcatPath.substring(0, tomcatPath.indexOf(projectName)) + "uploadFile";
File dest = new File(filePath, fileModel.getImageFileName());
try {
FileUtils.copyFile(fileModel.getImage(), dest);
} catch (IOException e) {
e.printStackTrace();
}
return "success";
}
}
if you implements the function based on my answer,please reply to
me,smile.

1) You have MySQL connection exception as below:
Establishing SSL connection without server's identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set.
To resolve this use the connection string like below:(change the db name to your existing db name)
jdbc:mysql://localhost:3306/dbname?autoReconnect=true&useSSL=false
This needs to be sorted first, that's why the values of the variables are not been rendered
2) In the Latest trace the requested list key 'projectidList' could not be resolved as a collection/array/map/enumeration/iterator type.
This error occurs when you try to access a list/collection which haven't been created.
Try to initialize the collection objects List<String> projectidList at class level.
when particular action is triggered at that time, JSP page is not knowing the the type of field, in this case, when you write List<String> projectidList = new ArrayList<String>(); instead of this, change it to ArrayList projectidList = new ArrayList();.
Make sure that you access list after the action class is instantiated i.e. corresponding action is called.
If you want to directly access it before calling action make it static and access it inside jsp.

Could not access bean in action Struts2

I have index.jsp where I have one link,on clicking on that link that page specific action gets called.Now as on the click of this link,I need to display a page with already populated multiselect list along with few input text fields,in the constructor of the action I populated the TransactionBean which will be bound with fields on next page i.e transactionData.jsp.
The transactionData.jsp page is getting displayed correctly with populated multiselected list.Now user can select values from multiselect list and can enter dates in text field and will click on click button,so that a bar chart is displayed.
On click on Click button ,I am calling another action ,which also has TransactionBean as its property.In the execute method of this action, I am trying to access transactionbean with its getter but it gives me NullPointerException. I got to know that, if we are submitting a page which has fields of bean binded ,then on calling action,bean will be instantiated automatically through interceptors but seems like something is not correct here.

Always use the latest version. At the moment it's Struts 2.3.16.3 GA. You can also see Version Notes and Migration Guide.

When i submit the registration form , the input values pass to Action class is null. How can i access the registration values in action class under register() method.
The above issue is resolved .
Now i'm facing another strange issue .. When i submit the form action = getLogin.action , its always returning INPUT from the interceptor . I dont wish to exclude the method login from the validator.
How could i resolve it ?
When i change the struts xml like below , its redirecting to success jsp . But i dont want to exclude the login method from validation
<action name="getLogin" class="login.action.LoginAction"
method="login">
<interceptor-ref name="defaultStack">
<param name="validation.excludeMethods">login</param>
</interceptor-ref>
<result name="success">/Success.jsp</result>
<result name="input">/LoginError.jsp</result>
</action>
You are using only one Interceptor, you need to use the whole Stack:
Change this:
<interceptor-ref name="validation">
<param name="excludeMethods">register</param>
</interceptor-ref>
to this
<interceptor-ref name="defaultStack">
<param name="validation.excludeMethods">register</param>
</interceptor-ref>

... You're throwing that exception, precisely where the stack trace tells you you are.
Are you unaware of Java stack traces? Are you unable to read the information it provides?
It's pointing to your code.
First of all defaultStack already includes fileUpload interceptor so you have to configure that interceptor instead of adding it twice to your action interceptors stack.
<action name="uploadAction" class="com.scrolls.fileupload.action.UploadImageAction" method="uploadImage">
<interceptor-ref name="defaultStack">
<param name="fileUpload.maximumSize">2097152</param>
<param name="fileUpload.allowedTypes">
image/png,image/gif,image/jpeg,image/pjpeg
</param>
</interceptor-ref>
<result name="success">ImageUploadSuccess.jsp</result>
<result name="input">index.jsp</result>
</action>
Second: in Struts2 you do not need to read submitted file from request. Read about file upload http://struts.apache.org/2.x/docs/file-upload.html.
You can try download example project from this link.

I have tried it already, it works.(thanks to the tutorial creator)
