Quindi cercate di capire la mia domanda e mi danno una buona soluzione per quanto riguarda il mio level.Because alcune soluzioni sono di altissimo livello non può in grado di capire per me.So si prega di dare la soluzione con buoni esempi.
Il mio progetto vale a dire "productionmgntSystem" è in "ofbiz / hot-deploy" folder.In mio progetto ho avuto un file vale a dire "app_details_1.ftl" con le seguenti codifiche
<html>
<head>

function logout1()
{
//alert("Logout1");
alert("<@ofbizUrl>logout1</@ofbizUrl>");
window.location='<@ofbizUrl>logout1</@ofbizUrl>'

Non posso in grado di risolvere l'issue.So si prega di aiutarmi a risolvere il problema.
Grazie e saluti, Sivakumar.J
Soluzione
Nel metodo Uploading.uploadFile() ci sono due linee (vicino alla fine) in questo modo:
byte[] extract_bytes=null;
byteWrap.get(extract_bytes);
Perché si passa un array di null metodo get() si stanno ottenendo un NullPointerException.
