Hello, this is my first question in bonitasoft community forum, and… I dont speak english very well so I must apologise for that…  
Well the question is I’m currently using bonita 6.5.3 with very good results, but with the new vertion released i’m triying to upgrade to bonita 7.x.x.  
My first step was import the actual process (6.5.3) to the design enviroment and try to run the process but i’m getting stuck in an assignment that return a java.util.list as the result of reading an excel document.

The code is the next:

`
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.ss.usermodel.DateUtil
String nombre_file = “erSel.xlsx”;
List Tabla = new ArrayList();
List Fila = new ArrayList();
File temporal = new File(nombre_file);	//se crea un puntero file temporal
FileOutputStream data_out= new FileOutputStream(temporal); //se crea un puntero para escribir en el archivo creado
data_out.write(doc_a_cargar.getContent()); //se carga con el puntero outputstream el contenido obtenido desde el archivo en el form de bonita
data_out.close(); //se cierra el puntero de escritura para liberar el archivo y dejar disponible su lectura
InputStream ExcelFileToRead = new FileInputStream(nombre_file); // Se carga el puntero de lectura con el archivo recientemente creado
XSSFWorkbook wb = new XSSFWorkbook(ExcelFileToRead); // Se carga el libro excel desde el puntero de lectura
`

`XSSFSheet sheet = wb.getSheetAt(0); // Se carga la primera pagina del libro apuntado
XSSFRow row;
XSSFCell cell;
int noOfRows = sheet.getLastRowNum();
int noOfCols = 0;
int i, j;
Iterator it_fila = sheet.rowIterator();
if (it_fila.hasNext())
{
row = (XSSFRow) it_fila.next();
//get the number of cells in the header row
noOfCols = row.getPhysicalNumberOfCells();
}
for (i = 0; i <= noOfRows; i++){
for (j = 0; j < noOfCols; j++){
if(sheet.getRow(i).getCell(j) != null){
if (sheet.getRow(i).getCell(j).getCellType() == XSSFCell.CELL_TYPE_STRING){
Fila.add(sheet.getRow(i).getCell(j).getStringCellValue());
}
else if(sheet.getRow(i).getCell(j).getCellType() == XSSFCell.CELL_TYPE_NUMERIC){
if(DateUtil.isCellDateFormatted(sheet.getRow(i).getCell(j))){
Fila.add(sheet.getRow(i).getCell(j).getDateCellValue().format(“dd/MM/YYYY”));
}
else {
Fila.add((int) sheet.getRow(i).getCell(j).getNumericCellValue());
}
}
else{
Fila.add(“”);
}	
}
else{
Fila.add(“”);
}	
}
Tabla.add(Fila)
Fila = new ArrayList();
}
return Tabla
`

I’ts a very simple code but helps me a lot loading data from excel documents and works very fine in the 6.x.x versions, this is the engine log:

It looks like you’re missing something from the prerequisites or /lib folders.

Looking at the missing class CTExtensionList on [http://snacktrace.com/search/CTExtensionList/pages/1](http://snacktrace.com/search/CTExtensionList/pages/1) shows several requirements for the class.

You should check the jars you’ve copied from the old environment to the new.

Hi and welcome…

A small hint here. Don’t use the “code” buttons from Bonita (as above) they don’t work as you can see,

Start code and log blocks with \< code \> and end with \< /code \> _removing the spaces_ and it will format the code and logs correctly/better.

Allows us to read them better…

I’ll get to look at this later

regards  
Seán

Importing this jar “ooxml-schemas-1.1.jar” my process was able to run without problems, i dont know why in the 6.x.x versions was running fine (i never import this file).  
I can continue working now, thanks for all Sean

You’ve done it by ticking the big arrow. Thanks
