سؤال

this is my JSP page... to upload EXCEL file...where I need to uplode 2 different excel file for different action... I hope the tag I is self explanatory...

<body>
<s:actionerror />
<s:fielderror />
<s:form action="Admin" method="post" enctype="multipart/form-data" theme="simple">
<big>Import Batch and Tan Details</big>
<br>
<s:file name="uploadToBatch" label="Select a Excel File for Batch import" />
<s:submit action="ImportBatchAndTanDetailsAdmin" value="Import" />
<br>
<big>Allocate Batch</big>
<br>
<s:file name="uploadToAllocate" label="Select a Excel File for Allocation" />
<s:submit action="AllocateAdmin" value="Allocate" onclick=""/>
</s:form>
</body>

next is my strut.xml configuration for these 2 actions...

<action name="*Admin" method="{1}" class="controller.AdminAction">
            <interceptor-ref name="fileUpload">
                <param name="maximumSize">2572864</param>
                <param name="allowedTypes">application/ms-excel,application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet</param>
            </interceptor-ref> 
            <interceptor-ref name="defaultStack"></interceptor-ref>
            <result name="error">adminPage.jsp</result>
            <result name="input">adminPage.jsp</result>
            <result name="success">adminPage.jsp</result>
        </action>

next is the action class...

package controller;

import java.io.File;
import jxl.Sheet;
import jxl.Workbook;
import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class AdminAction extends ActionSupport {

    private File uploadToBatch;//The actual file
    private File uploadToAllocate;
    private String uploadContentType; //The content type of the file
    private String uploadFileName; //The uploaded file name
    AuthorIndexingDAO DAO = new AuthorIndexingDAO();

    //getters and setters... 
    public File getUploadToBatch() {
        return uploadToBatch;
    }
    public void setUploadToBatch(File uploadToBatch) {
        this.uploadToBatch = uploadToBatch;
    }
    public File getUploadToAllocate() {
        return uploadToAllocate;
    }
    public void setUploadToAllocate(File uploadToAllocate) {
        this.uploadToAllocate = uploadToAllocate;
    }
    public String getUploadContentType() {
        return uploadContentType;
    }
    public void setUploadContentType(String uploadContentType) {
        this.uploadContentType = uploadContentType;
    }
    public String getUploadFileName() {
        return uploadFileName;
    }
    public void setUploadFileName(String uploadFileName) {
        this.uploadFileName = uploadFileName;
    }



     //ececute method...


    public String execute (){
         return SUCCESS;
     }


     //other methods....
     public String ImportBatchAndTanDetails(){

         try {

                Workbook w;

                    w = Workbook.getWorkbook(uploadToBatch);
                    Sheet sheet = w.getSheet(0);
                    System.out.println(sheet.getName());


                    } catch (Exception e) {
                            e.printStackTrace();
                            System.out.println(e.getMessage());
                            addActionError(e.getMessage());

                    return ERROR;

                    }

         return SUCCESS;
     }


public String Allocate(){

         try {

             System.out.println(uploadFileName);
             System.out.println(uploadToAllocate.getName());

                Workbook w;

                    w = Workbook.getWorkbook(uploadToAllocate);
                    Sheet sheet = w.getSheet(0);
                    System.out.println(sheet.getName());


                    } catch (Exception e) {
                        e.printStackTrace();
                     return ERROR;

                    }

         return SUCCESS;
     }

}

while I import I get this in console...

null
upload__6e26fdaa_137cba00800__8000_00000001.tmp

and the exception thrown near w = Workbook.getWorkbook(uploadToAllocate); was...

I have found the reason. The excel which I imported is not created in a proper manner it seems so while I copied the content and pasted it in a new excel and saved it. Later when I import this new excel it works fine.

You have used jxl api, jxl supports only .xls extension and older, it does not support newer exensions such as .xlsx You should have used a incompatible extension most probably .xlsx that's why
'jxl.read.biff.BiffException: Unable to recognize OLE stream ' exception is thrown. just try a using a file with .xls extension or instead of using jxl api use poi.
