public void sendMailsTest(String hostName, int portNo, final String userLoginId,
final String userPassword, String mailtoUser, String userName,
DocumentDetails mailDetails,String fromUserName, int type,
List<User> mailBodyDetails,ArrayList<String> ccList) {
String line1 = "This is an auto generated e-Mail don't reply";
String mailto=mailtoUser;
String from =userLoginId;
for(int i=0; i<mailBodyDetails.size();i++){
if(mailBodyDetails.get(i).getMailTypeId() == type){
subject = mailBodyDetails.get(i).getMailSubject();
body = "body";
}
}
