Validate JTextComponent for being empty

well, I think the method could be like this:
 public Object validaDatosReturnArray(MyTextField cod, MyTextField nom,
 MyTextField ape, MyTextField dir, MyTextField fono,
 MyPasswordField pass) {
 Object[] datos = { "Error en el Ingreso Datos",
 Utilitario.getContenido(cod), Utilitario.getContenido(nom),
 Utilitario.getContenido(ape), Utilitario.getContenido(dir),
 Utilitario.getEntero(fono), Utilitario.getContenido(pass) };
 System.out.println("Cod : " + datos[1].toString());
 System.out.println("Nom : " + datos[2].toString());
 System.out.println("Ape : " + datos[3].toString());
 System.out.println("Dir : " + datos[4].toString());
 System.out.println("Fono: " + datos[5].toString());
 System.out.println("Pass: " + datos[6].toString());
 Empleado u = ListaEmpleados.getElemenAt(datos[1].toString());
 if (u == null) {
 if (datos[1].toString() == null)
 Utilitario.mensaje("Falta Codigo", datos[0].toString(), 1);
 else if (datos[2].toString() == null)
 Utilitario.mensaje("Falta Nombre", datos[0].toString(), 2);
 else if (datos[3].toString() == null)
 Utilitario.mensaje("Falta Apellido", datos[0].toString(), 3);
 else if (datos[4].toString() == null)
 Utilitario.mensaje("Falta Direccion", datos[0].toString(), 3);
 else if (Integer.parseInt(datos[5].toString()) == -1)
 Utilitario.mensaje("Falta Telefono", datos[0].toString(), 2);
 else if (datos[6].toString() == null)
 Utilitario.mensaje("Falta Clave", datos[0].toString(), 2);
 return datos;
 } else
 return null;
and the setEmpleado method() :
public void setEmpleado() {
 Object[] datos = (Object[]) validaDatosReturnArray(txtCodigo,
 txtNombres, txtApellidos, txtDireccion, txtTelefono, jpsClave);
 Empleado u = ListaEmpleados.getElemenAt(datos[1].toString());
 if (datos == null) {
 System.out.println("Aqui esta tu arreglito ktm" + datos);
 } else {
 u = new Empleado();
 u.setCodigo(Utilitario.formatoMay(datos[1].toString()));
 u.setNombre(Utilitario.formatoMay(datos[2].toString()));
 u.setApellido(Utilitario.formatoMay(datos[3].toString()));
 u.setDireccion(Utilitario.formatoMay(datos[4].toString()));
 u.setTelefono(Integer.parseInt(datos[5].toString()));
 u.setClave(Utilitario.formatoMay(datos[6].toString()));
 ListaEmpleados.add(u);
 GUI.aviso(this, "El registro se grabo correctamente");
 Utilitario
 .mensaje("<html>Datos de Nuevo Empleado:"
 + " C�digo :" + datos[2].toString()
 + " Nombre :" + datos[3].toString()
 + " Apellido :" + datos[3].toString()
 + " Direccion :" + datos[4].toString()
 + " Telefono :" + Integer.parseInt(datos[5].toString())
 + " Contrase�a :" + datos[6].toString(),
 "Importante", 1);
 listarEmpleados();
 txtCodigo.setText(setCodigo(ListaEmpleados.ls));
 }some one can do it better or give ideas to build a method able to validate his parameters (JTextComponents) for being empty ?
Another cue:
Is better to return an Array of JTextFields in this method?, because i will do a getText() from each JTextComponent validated to be empty for extracting the date from each one to insert in a DinamicList (LIFO)
*the method to insert is ready, i just want to know what do you think about this possibility from validate JTextComponents

Unable to validate security for resource 'EXTRANETLOOK'

We have UCM 10gR3 installed. We have Extranetlook component installed along with WebDAV. Currently when the users take any action that they don't have privilege to, they come accross Unable to validate security for resource 'EXTRANETLOOK'error message. Before it use to give exact error message so that it was easy for us to troubleshoot. Recently due to some changes in the settings in the system, we started seeing this error message instead of actual error message something like Unable to retrieve page. User 'abc ' does not have sufficient privileges. Is there a way to suppress thie Extrenet look error message so that the actual message comes through?
thanks,

Thanks for the response Bernhard. I'd like to address some of the points you mentioned:
possibly you have not the permissions to add resources
-I am an owner of both the PWA and the project subsite
there are no resources inside your project plan (you have to use the "Build Team" in the Ribbon)
-I checked the "Build Team" list and confirmed there are a dozen users in there
not each view allows you to edit each field
-I've tried switching views and noticed that there are other fields that I cannot add values into including: Actual Start, Actual Finish, Baseline Finish, % Work Complete. I am able to change the Task Name, Start, Finish.
Very strange problem. Im still doing development on it but obviously cant roll this into production when users cannot add information to tasks.

How to validate ME21N for PO Date sy-datum using BADI

Hello Experts,
I've a requirement in which I've to validate ME21N for PO Date < sy-datum. So which METHOD of which BADI I've to implement to get this done.
Thanks in advance..
Best Regards,
Hardik B

Hi Hardik,
Please try writing your code in method POST of BAdI ME_PROCESS_PO_CUST.
If you want to search for a BAdI for a particular T-code, Go to t-code SE24. Enter class name as cl_exithandler, put a break-point on method GET_INSTANCE of this class and come out of it. Enter the t-code for which you want to find a BAdI. Once the program stops in the debugger, you can find the BAdIs and user exits in the exit_name parameter of the method get_instance.

CHARGED TIME AND MONEY FOR BEING MISINFORMED-COMPLAINT

Today I received my Verizon Wireless bill and I noticed that I was being charge overage for data usage of $45.00 (3 X $15.00 per 250mb over). Now I've been with Verizon for over 10yrs and always loved the service and plans that they've provided until recently.I switched to the lowest plan of $45 per line w/250mb of data due to my financial situation currently. I called and spoke to a rep to see about the overage charges, but was told before I could be transferred to dept that handles that issue would need to setup arrangements to pay due amount. I let the rep know that I do have arrangements setup and should be noted. She quickly stated that my arrangements was for last months bill and I would need to setup arrangements for the current. I gave her amount and date that I would be able to pay, which she informed me that the arrangements would not be able to guarantee a continuation of my service. I asked her why was I able to setup arrangement with the previous rep for a lesser amount plus more time and my service would continue as long as I kept my agreement, but she's not able to do the same. She sold cause my account would continue to be behind cause another payment would be coming due as I'm paying off the previous month. I asked to speak to retention dept, which I was told that she couldn't transfer me, but would get me a supervisor to see what they could do for me. I spoke to the supervisor, which I again was told the exact same thing as the previous rep had already discussed and felt like I wasn't getting anywhere now. I requested to speak to retention at this point and was transferred. The young man I spoke to stated off very pleasant and when I told him my situation, seemed like he was more then willing to help. I asked for to be able to pay an amount and gave a date again, which he stated that he couldn't meet the arrangements cause would put account too far past due and lines would be interrupted at point. I thanks him for the explanation and wanted to see about setting up better arrangements. I gave another amount which was shot down again. Then he offered to suspend my account until I could caught up the bill to help me out. Really???? I let him know that he needed to be more realistic and see how you really can live w/o a cell phone in this day and era. At this point, I felt like he wasn't giving me anything to work with and was only concerned about me paying the bill. I quickly let him know that although I do love Verizon service, they're not the cheapest out there and had several other options to choose from with other providers. After we both went back and forth trying to see how wore the bigger pants, we both came to a agreement to settle my bill within 2 payments broke up. Now I've been on the phone for about 45mins and still yet to even speak to someone about the original issue I was calling about. Finally, I was being transferred to CS dept. While holding, I was able to get into the Family Base setting and set limits on the 2 phone under me to block usage once 250mb limit was reached. I got a rep by the name of Christian and explained to him about the overage charges that I was charged on my bill and that I signed up for the Family Base feature to block overage usage, cause when I switched to this new plan I was told that I couldn't block limit on data for my plan cause was too low and would have to move up to a plane with lines at least 500mb. I told him that's the reason why I signed up for the Family Base cause it stated that would block data usage once limit reach and thought would do automatically since they bill me automatically when I go over. He said that is correct, that I'm not able to set a block on data overage under 500mb. I let him know that's not the cause and that I was able to setup usage block on phone online, but again I didn't know I had too or that I could, cause I was misinformed by the previous rep, just as he was misinforming me again and asked that I be credited $45.00 for being misinformed. He said that he would see what he could do and offered to take 25% off the overage changes. I said, no I believe that I need to be credited the full amount due to being misinformed by previous rep and now him. I explained to him that I believe this new planned was rolled out before they could make some adjustments to some of the features and that's why the limit wasn't available to be set at the time I switched my plan or on the Family Base feature until a later date. So Christian then said that he could give a $20.00 credit to fees. Again, I explained to him that I shouldn't have to pay for being misinformed and requested to speak to a supervisor. He tried to tell me that a supervisor wouldn't be able to give me anymore credit and that would take a long time to speak to one. I still insisted on speaking to one. At this point, I've now been on the phone 1hr 30mins and was placed on hold. Christian came to the line a couple of times letting me know that he was still waiting on a supervisor, which I let him know that was fine. He then came back to the line and told me that he had reviewed the account w/supervisor and that they credited $20.00 and that was the best that could be done cause data was used. I asked him, if the supervisor was reviewing the account with him, why wasn't I able to speak to them as I requested? So, I'm placed on hold again and after about 10mins was finally placed on line with Kim ID#159079, so I explained my situation and feelings towards being misinformed and how I believe that I shouldn't have to be help accountable if I'm being misinformed by reps about features. From there she went right in and told me that the credit that I was giving was more than enough and that Christian went over what he was supposed to do already and that no other credit would be offered to my account. Now that I see that I've wasted my time, I asked for her ID and Christians ID info. She gave me her's, but decline to give me his and said that if I didn't get it at the time I was talking to him, that she wasn't authorized to give his cause was sensitive information...??? You're a supervisor and I know working in a call center myself, that's the reason why your given ID# so you don't to give out you true info. Needless to say I spent 1hr 51mins on the line for a $20.00 credit for being misinformed, which is less the amount I get paid on my real job. Very disappointing. Can someone please help better my situation and Verizon experience???

Simply because you disagree with the amount of credit they have given you does not mean that they will give you more, or that you deserve more. If going over your data allowance is that important to you, you should have kept better track of your usage. You can place a counter on your home screen which tells you how much you have used. It isn't up to the minute accurate, but you would certainly have been aware that you had used 4 times your monthly allowance.
Whether or not you were misinformed about usage limits being available, you used 4 times your monthly allowance. Take some responsibility, keep track of your usage. It is not hard to do.
Additionally, Verizon expects you to keep up to date on your bill. Yes, they will give you a break when you get an overage and request a payment schedule, but when you call the very next month in order to do the same they are going to be a bit more strict on their terms because they do not want this to become a pattern. If you would have taken a fraction of that overage, you could have stepped up to the next level of service and been able to cover all of your usage. This is what Verizon expects of you if you have an overage. You should reevaluate your usage habits and change your allowance OR rein in your usage to meet your current allowance. If you fail to rein in your usage to meet your current allowance, I would not expect Verizon to be as lenient with payments for a what appears to be a chronic overage patttern when simply increasing your allowance would have lowered your bill in the first place.

I need a method for ignoring empty lines

Hi to all,
i need a method for ignoring empty lines when my program reades a file like that
start of file
print "xoxox"
//ignore this line
println"xaxaxa"
//ignore this line
end of file
cheers

Are you having trouble detecting these empty lines? Or are you having trouble not processing them once you've detected them?
For the first case, you neeed to define "empty." I assumed it meant "containing no characters," and that's what the first solution shows. Your example looks like "empty" means "starts with comment characters."
For the second case, you ignore them by just not doing anything: read a line
if (it is not empty) { // by whatever criteria you define for "empty"
do something with it
}

I bought a MBP 13 and I got the £70 App Voucher for being a student, I know want to return the MBP how can I do that? can I just pay the £70 for the app store voucher or what do i need to do? MacBook

I bought a MBP 13 and I got the £70 App Voucher for being a student, I now want to return the MBP how can I do that? can I just pay the £70 for the app store voucher or what do i need to do?

If you have redeemed the voucher for something separate from the computer, then it's a non-issue. If you redeemed it as a price reduction for the computer, then they will return only what you paid less the coupon.

"Field ID of Standard Location Structure for Development empty" error?

Hi there
I am implementing the land use management enhancement. It allows me to define an object called a "Public Register" which represents a "set" of land objecs (land parcels, rental units, etc) under special circumstances such as hazardous areas.
Unfortunately it returns two errors on validation/save:
Field ID of Standard Location Structure for Development empty
Field ID of Standard Location Structure for Easement Reg empty
It has no description or reference to any documentation.
What could this error mean?
Regards
Joe

Hi Joe,
could you please tell me the ID and number of the error messages.
Thanks.

Can not create planning function types (for process empty records)

Hi! SAP Experts,
I want to copy 0RSPL_FORMULA to another function types for processing empty records, ZRSPL_FORMULA. I checked this function type via RSPLAN, there is no error!. But when i try to use it in planning modeler. We found the error message "Infoobject 1FORMULA is does not available in version A". Do we need to create this infoobject?... Anyone know, please let me know.
Thanks,
Sake

Hi!,
Thanks for your help but I've already put that parameter,HIDDENFORMULAVARTAB->1FORMULA, in my planning function, ZRSPL_FORMULA. I validated it and no error found. But when I go to planning modeler, in web browser, and try to create a new planning function based on ZRSPL_FORMULA. I found the problem as I mention in previous message, "infoobject 1FORMULA is not available in version A". I try to search this infoobject in my system. The result is there is no this infoobject in my system. So, my question is do i need to create it with myself? What kind of infoobject i have to create? Key Figures or Characteristics?
Anyway, If I have to do this, why 0RSPL_FORMULA still used as normal.
Brgds,
Sake

When validate item for a particular item number

hi all
i am using forms 6i
In a master detail form
the block XXNP_JL_OO1 has 2 fields like
Manual--checkbox item
Field--text item (populated from Lov RECORD group names Field)
the query for the record group of FIELD is
select flex_value from fnd_flex_values where flex_value_set_id=1009757
flex value
abdaly
wafra
fintas
now if we do the query select flex_value, hierarchy_level from fnd_flex_values where flex_value_set_id=1009757
flex_value hierarchy_level
abdaly 315
wafra 200
fintas 100
In the detail part
there is a tabbed canvas one field is ACT_QTY
ITEM NUMBER                   ACTQTY
client requirement is whenever the item number is 1010103002 only and the manual checkbox item is ticked the act_qty should return values corresponding to the data in Field
manual and field belongs to datablock XXNP_JL_001
ITEM_NUMBER AND ACT_QTY belongs to data block xxnp_jl_est_002
kindly guide how to proceed with this
should i do a when validate item trigger in act_qty as follow
BEGIN
    IF :XXNP_JL_001.Manual IS NOT NULL and XXNP_JL_EST_002.ITEM_NUMBER='1010103002' THEN
        SELECT hierarchy_level

FB4 Beta 2 error message on "validate configuration" for web root

Hello:
I have been working in FB4 beta 1 and had a php project working fine. After installing FB4 beta 2, i am now having problems with the flex server web root and/or root URL. i am now getting the following error message when I try and "validate configuration" for a configuration which had been working. The error message is:
"(the web root) is not a valid location because the project contains a linked resource at that location"
Here are my settings which had been workin g with FB4beta1, but which now result in the error message with FB4beta2:
>> web root c:\wamp\www
>> root URL: http://localhost
>> output folder: c:\wamp\www\projectname-debug
I am running wamp server on my local machine as my testing server; I run windows XP pro; this is a php project
Has anyone seen this problem in FB4 beta2?
thanks very much

I just recently had this issue myself but I did a Clean on my project and it seems to working fine now.
Hope this helps if you are still having this issue.

I bought an iPhone 5. I was at work event and left cord in hotel. I've visited 2 apple stores and it looks very bleak. HUGE regret for being an early adopter. Consumer BEWARE. Apple was not prepared. These cords are impossible to find

I can not confirm this kind of experience.
Even here in Germany, where articles are sold after the U.S. market is supplied, I had no problem buying a Lightning cable yesterday.
There were about 20 to 30 cables available in the customer area alone, not to mention what they perhaps had in their storage.
So why not make a short trip to Munich, Bavaria, visit the Octoberfest and buy a Lightning cable.
What makes me much more angry is that I was told there is no dock planed for the iPhone 5.
