Hi All,
I've problem with my program which includes Struts framework.
If I run my application it displays the first values. If I insert another values in to the arraylist, current values is overwrtten with previous values and also copied to the next place and son in the 3rd time when inserting..

Here's My Code.

AdminAction.java

StudentBean.java

public class StudentBean 
{
	public String sName;
	public String sGender;
	public String sAddress;
	public String sContactNo;
	public String sCollegeName;
	public String sBranch;
	public String sCetRank;
	
	static ArrayList<StudentBean> stList=new ArrayList<StudentBean>();
	
	
	public String getsName() 
	{
		return sName;
	}
	public void setsName(String sName) 
	{
		this.sName = sName;
	}
	
	public String getsGender() 
	{
		return sGender;
	}
	public void setsGender(String sGender) 
	{
		this.sGender = sGender;
	}
	public String getsAddress() 
	{
		return sAddress;
	}
	public void setsAddress(String sAddress) 
	{
		this.sAddress = sAddress;
	}
	public String getsContactNo() 
	{
		return sContactNo;
	}
	public void setsContactNo(String sContactNo) 
	{
		this.sContactNo = sContactNo;
	}
	public String getsCollegeName() 
	{
		return sCollegeName;
	}
	public void setsCollegeName(String sCollegeName) 
	{
		this.sCollegeName = sCollegeName;
	}
	public String getsBranch() 
	{
		return sBranch;
	}
	public void setsBranch(String sBranch) 
	{
		this.sBranch = sBranch;
	}
	public String getsCetRank() 
	{
		return sCetRank;
	}
	public void setsCetRank(String sCetRank) 
	{
		this.sCetRank = sCetRank;
	}
	public static ArrayList<StudentBean> getStList() {
		return stList;
	}
	public static  void setStList(ArrayList<StudentBean> stList) {
		StudentBean.stList = stList;
	}
	
}

Welcome to the JavaRanch. I added Code Tags to your post to make the code easier to read. Please use them in the future.

Your code is confusing. The StudentBean is both a single student and a collection of students? That's a Bad Idea.

HI.. Joe Ess StudentBean is bean class. which gets data from the StudentForm class.
I'm using this StudentBean Class to display data using <logic:iterate> tags.

Even I used static arraylist.

My Output Example:
After submitting the form for Sandeep
Sandeep: Your Request Receieved

After submitting the form for Anand.
Anand: Your Request Receieved

I need to get the output in display.jsp like:[Exapected]

Sandeep
Anand

but actual output i'm getting
Anand
Anand.

Please Help Me.

Thanks and Regards,
Sandeep
