Null value coming from Database

Code Java:

---

Installed_optionsHome inopthome = (Installed_optionsHome)jndiContext.lookup("installed_optionsCFY.Installed_optionsHome");
Enumeration installed_options = inopthome.findBySiteId(siteId);
while (installed_options.hasMoreElements()) {
    installedOptionsObject = (Installed_options)installed_options.nextElement();
    insOpt=installedOptionsObject;

---

-----The below code worked earlier

Code Java:

---

if (installedOptionsObject.getService_options_name().equals("Self Install")) {
    OptionsName = installedOptionsObject.getService_options_name();
    instStatus = installedOptionsObject.getStatus();
    Logging.log("OptionsName " + OptionsName , Logging.DEBUG);
}
 
if ((installedOptionsObject.getStatus()).equals("ADD")) {
 
 
    //Update IP Count if found
    if ((installedOptionsObject.getService_options_name()).equals("Addl IPs")) {
    }

---

Code Java:

---

    //Update Mail Count if found
    if ((installedOptionsObject.getService_options_name()).equals("Mail")) {
// Update Mail Count
if (mailCount != -1) {
    Logging.log(method + "Mail Count = " + mailCount, Logging.DEBUG);
    installedOptionsObject.setQuantity(mailCount);
    mailFound = true;
} else {
    Logging.log(method + "Mail Count not received", Logging.DEBUG);
}

The scenario is like when I am trying to get the value from a field in a record from the database, I am getting null value. Which is in turn causing me to create a new record with a null value in a field. Basically this code was working for about 6 years. And now there is no code change to this particular file. There is value in DB field say "Service_Options_Name" ,yet it is taking the null value and when I change the code as mentioned below, its working.

Now the change is as follows:

Code Java:

---

                while (installed_options.hasMoreElements()) {
                    installedOptionsObject = (Installed_options)installed_options.nextElement();
                    insOpt=installedOptionsObject;
                    if ( (new Integer(installedOptionsObject.getAccess_seq()).toString()).equals(accessSeq)) {
                        //following condition was added for IP Letter Validation
                    	String serviceOptionName="";
                    	if(installedOptionsObject.getService_options_name()!=null)
                    		serviceOptionName=installedOptionsObject.getService_options_name();
 
                        if (serviceOptionName.equals("Self Install")) {
                            OptionsName = installedOptionsObject.getService_options_name();
                            instStatus = installedOptionsObject.getStatus();
                            Logging.log("OptionsName " + OptionsName , Logging.DEBUG);
                        }
 
                        if ((installedOptionsObject.getStatus()).equals("ADD")) {
 
 
                            //Update IP Count if found
                            if (serviceOptionName.equals("Addl IPs")) {
 
                                // Update IP Count

Code Java:

---

                            //Update Mail Count if found
                            if (serviceOptionName.equals("Mail")) {
                                // Update Mail Count
                                if (mailCount != -1) {
                                    Logging.log(method + "Mail Count = " + mailCount, Logging.DEBUG);
                                    installedOptionsObject.setQuantity(mailCount);
                                    mailFound = true;
                                } else {
                                    Logging.log(method + "Mail Count not received", Logging.DEBUG);
                                }
 
                            }

I think the problem behind this issue is when I assign the options name from DB to another string object, it is working. Else it is not working.

Can someone pls let me know what is wrong here?
