Now I am ready to include my first POJO into the app.

I tried @Autowire in the line prior to my new attribute, in one of the autogenerated controllers, just copying the approach in the generated code.

Get error
org.springframework.beans.factory.BeanCreationException: Could not autowire field: …

Can you explain how to autowire in propriatary beans? Any background on autowiring approach use by Myeclipse would be of interest.

Regards

Greg

Hi Greg,

Just to clarify – the annotation is @Autowired (with a “d” at the end). Assuming, you know this – but want to make sure.

The POJO does need to be recognized as a Spring bean.

When you get a moment, please post the POJO and other bean you are trying to autowire into.

Thanks,
Dave

This is the POJO

package prop;

import java.io.FileOutputStream;
import java.util.Calendar;
import java.util.Iterator;
import java.util.Set;
import java.util.jar.JarFile;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Date;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CreationHelper;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;

public class Scores_to_spreadsheet {

/**
* @param args
*/
private JarFile file;
private Short dd;
public static void main(String args[]) throws Exception {
System.out.println(“Got in”);
Scores_to_spreadsheet test = new Scores_to_spreadsheet();
test.generate_scores2(args[0]);
}
private JarFile getFile() {
return file;
}

private void setFile(JarFile file) {
this.file = file;
}

public String generate_scores2(String campaign_code) throws Exception
{
Workbook wb = new HSSFWorkbook();
//Workbook wb = new XSSFWorkbook();
CreationHelper createHelper = wb.getCreationHelper();
Sheet sheet = wb.createSheet(“new sheet”);

// Create a row and put some cells in it. Rows are 0 based.
Row row = sheet.createRow((short)0);
// Create a cell and put a value in it.
Cell cell = row.createCell(0);
cell.setCellValue(1);

// Or do it on one line.
row.createCell(1).setCellValue(1.2);
row.createCell(2).setCellValue(createHelper.createRichTextString(“This is a string”));
row.createCell(3).setCellValue(true);

// Write the output to a file
FileOutputStream fileOut = new FileOutputStream(“/home/innovativ/Desktop/workbook.xls”);
wb.write(fileOut);
fileOut.close();
return “result is at ” + file;
}
}

This is the start of the autogenerated bean I would like to use the POJO

}

Campaigns campaigns = campaignsDAO.findCampaignsByPrimaryKey(campaignIdKey);

campaignsService.deleteCampaigns(campaigns);

return “forward:/indexCampaigns”;

}

/**

public String indexCampaigns() {

return “redirect:/indexCampaigns”;

}

/**

@InitBinder

binder.registerCustomEditor(java.util.Date.class, new org.skyway.spring.util.databinding.CustomDateEditor());

}

/**

@RequestMapping(“/editCampaigns”)

public ModelAndView editCampaigns(@RequestParam Integer campaignIdKey) {

ModelAndView mav = new ModelAndView();

mav.addObject(“campaigns”, campaignsDAO.findCampaignsByPrimaryKey(campaignIdKey));

mav.setViewName(“campaigns/editCampaigns.jsp”);

return mav;

}

Thanks for posting the classes.

So, the Scores_to_Spreadsheet POJO is not recognized by the Spring container. To get it recognized, you’ll need to annotate it, and then add it’s package to the component scan in the spring context files.

What I did to get this deploy is:
1. Annotated the Scores_to_Spreadsheet with @Service
2. Added the following to resources/[projectname]-generated-service-context.xml:

<context:component-scan base-package="prop" scoped-proxy="interfaces" />

HTH,
Dave

Ok, I even understand that. Progress! Many thanks
