Help with jpa paging exception

hi i have the following method that does paging in an ejb. (dont mind the string params, not using them yet)
@Override
public List<DatamainMst> findAll(String srchCallup, String srchSurname, String srchOthernames, String srchInst, String srchCourse,int first, int pagesize) {
List<DatamainMst> mst = em.createQuery("select o from DatamainMst o")
.setFirstResult(first).setMaxResults(pagesize).getResultList();
return mst;
my database table has about 61868 records. the whole paging works well until "first" argument is 61200, and irrespective of the page size, i always get the following exception:

i dont know what the problem is, it seems like an eclipse link problem?
what can i do?

Well look at the generated code and if you can fix it. The code generator might have a bug so it will be worth reporting it in the bugs database of the netbeans website.
But I would advise you to do the proper thing: don't generate code. Generate getters and setters, but don't let the entire entity be generated. Do the mappings yourself, determine for yourself where you need bi-directional mappings (hint: as little as possible). Make sure that you do EAGER and LAZY initialization in the proper places. Fine tune the nullable,insertable,updateable flags to help the ORM generate the most efficient (and correct) queries possible.
In other words take control, don't let the tool be in control.

Help with JPA Inheritance Relationship Mapping

Perhaps someone can help with this. I'm trying to figure out how to map what seems like a simple data model using JPA. But it is not working.
@Entity
public class Account {
    @OneToOne(cascade=CascadeType.ALL)
    private AbstractPaymentMethod paymentMethod;
@Entity
@MappedSuperClass
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="__CLASS__", discriminatorType=DiscriminatorType.STRING, length=20)
@DiscriminatorValue("AbstractPaymentMethod")
public abstract class AbstractPaymentMethod {
@Entity
@Table(name="payment_method")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="__CLASS__", discriminatorType=DiscriminatorType.STRING, length=20)
@DiscriminatorValue("CreditCardPaymentMethod")
@SuppressWarnings("serial")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class CreditCardPaymentMethod extends AbstractPaymentMethod {
    @Column
    private String expirationDate;
}The problem is, when I add a CreditCardPaymentMethod to an account like this...
Account account = new Account();
CreditCardPaymentMethod m = new CreditCardPaymentMethod();
account.setPaymentMethod(m);
em.persiste(account);... The entity manager attempts to save account.creditCardPaymentMethod as an AbstractPaymentMethod.
Surely I'm doing something horribly wrong. Is there something I'm missing here?
Thanks for any help.

Thank you! You saved my life. After removing @MappedSuperClass, all is well.
The entity manager is now saving my CreditCardPaymentMethod objects as CreditCardPaymentMethod classes instead of AbstractPaymentMethod classes.

Help with Null Pointer Exception

Hi, I am working on a simple menu program. It compiles and works correctly except for one item. I am having a problem with Greying out a menu item......

alan, I've been trying to figure out a solution.
You can initialize it like this
private Action saveAction= new Action();
     private Action saveAsAction=new Action();
THE ABOVE WILL NOT WORK.
because Action is an interface. An interface does not have constructors. However, interface references are used for polymorphic purposes.
Anyway, all you have to do is find some class that implemets Action interface.... I cant seem to find one. Or maybe this is not how its supposed to be done?
Hopefully, someone can shed some light on this issue.

Help with JPA

hi, hmmm i'm totally new to EJB, i must say JPA is confusing (at least for me), but "never give up, right?" , Ha!.
ok, m reading an article now, nd we have these two classes
@Entity
public class Inventory {
@Id
@Column(name="ITEM_SKU", insertable=false, updatable=false)
protected long id;
@OneToOne
@JoinColumn(name="ITEM_SKU")
protected Item item;
public void setItem(Item item) {
this.item = item;
this.id = item.getSKU();
//////////// and
@Entity
public class Item {
protected long SKU;
@Id
@GeneratedValue
public long getSKU() {
return SKU;
i think i understand the annotation part, my question is this?
1).does it mean the ITEM_SKU column in the inventory table will contain an object of Item entity or what?
2).are both entities persistable? if yes, if you persisit an inventory entity, what will the ITEM_SKU column contain?.
please, help and if u gat links to usefull material, please drop.
thanks.

Hi,
You will have two tables in the DB named Inventory and Item.
Inventory will have a column named ITEM_SKU. This is the primary key, and it's a foreign key to the second table Item. Item has a column named SKU.
The entities are persistable, however if you try to persist the inventory without an Item (null instance variable) you will probably get an exception, because the primary key, or the foreign key constraint will fail.
If it's not null, both objects will be persisted. So 2 records will be written into the database.

Need little help with JPA code and displaying database data into tables

Hello Everyone,
I am using java6 and Netbeans 6.1 on Windows XP platform.
This is probably very simple but have'nt been able to figure it out yet. I am using the Travel Java Databse included in NB6 as a learning tool.
I have a JComboBox connected to Person Table and want to display a Trip table from using the selected item from theJcombobox. In other words, Trip table shows only the Person selected from the Jcombobox.
If someone could point me on the right direction how to code JPA code or how to use NB6 GUI to accomplish this.
Thanks

The w and wi are just table aliases that make it easier to
referrence those tables by column when joining multiple tables
(avoids having to prefix column names with the entire table name,
etc.) When doing a self-join (joining a table to itself), the use
of table aliases is
required, otherwise you would have no other way to tell
which column belonged to which "instance" of table.
The query itself is pretty simple. It is just using a
correlated subquery to select only those instances of
workstationApps where the count of appID instances in
workstationAppIndex is less than the amount specified in the
maxConcurrentInstalls for the same appID.
Also, I do see what you are doing with #form.searchType#, I
was just making sure that it was what you really intended to do.

Help with New NumberFormat Exception

Hello. I'm new to java and I can't figure this out. I'm trying to prevent customers from entering a negative value for the quantity or price with a (quantity <= 0)New NumberFormat Exception but it's not working.

I suggest changing your code slightly. In the actionPerformed() method when you are calling other methods to parse the input, use a try/catch block around those methods. Something like thispublic void actionPerformed(ActionEvent e) {
 if(e.getSource() == calcButton) {
 try {
 Title = txtTitle.getText();
 Author = txtAuthor.getText();
 quantity = getQuant();
 price = getPrice();
 transCount();
 lastTot();
 numBooks();
 subTotal();
 salesTax = salesTax();
 shipping = shipping();
 total = total();
 answer = outFormat();
 } catch(NumberFormatException ne) {
 } else {
 //resetButton should clear all the fields.
 }Then, inside the methods that parse the data, change the code so the exception is thrown to the caller, something like this //Prevent user from entering invalid quanity numbers.
 public int getQuant() {
 boolean error = false;
 try {
 quantity = Integer.parseInt(txtQuantity.getText());
 } catch(NumberFormatException ne) {
 error = true;
 error = error | quantity <= 0;
 if (error) {
 statusArea.setText("Please enter a valid number for quantity.");
 throw new NumberFormatException();
 return quantity;
 }This allows the error to cause the program to skip calculating.
I also think you have a logic problem with how you are calculating shipping.

Help with: java.sql.SQLIntegrityConstraintViolationException

Hi, guys
I need help with the following exception: java.sql.SQLIntegrityConstraintViolationException: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'SQL090403155751200' defined on 'BOOK_ORDER'.
the things is my primary key is unique, so i checked the indexes and i found that i have two 'SQL090403155751200' indexes.
I would like to know:
1. can i delete the index without causing further database problems
2. what causes this problem and how can i avoid it.
By the way im using netbeans 6.5 and derby database

By understanding what the application/system is supposed to be doing and the correctly creating indexes on the database that reflect the business needs.
Once you do that then the nature of the indexes that are needed are obvious.
You certainly don't delete indexes without that understanding however.

I am experiencing exactly the same problems on one of two identical machines after something happened in the registry.
The first problem that appered was an error 1325 "Favorites is not a valid short name".
I did find the registry key involved (%userprofile%\Favorites) and fixed it.
So now the the next one: yours.
I think the solution can be found in the list of registry keys that Adobe Reader is accessing.
btw Eusing registry cleaner did not find this key to be in error.
Problem is that the Reader does not ask for an alternative location after stumbling on the key.
Who can gnerate a list of keys accessed?

Help with HP Laser Printer 1200se

HP Support Line,
Really need your assistance. I have tried both contacting HP by phone (told they no longer support our printer via phone help), the tech told me that I needed to contact HP by e-mail for assistance. I then sent an e-mail for assistance and got that reply today, the reply is as follows "Randall, unfortunately, HP does not offer support via e-mail for your product. However many resources are available on the HP web site that may provide the answer to your inquiry. Support is also available via telephone. A list of technical support numbers can be round at the following URL........." The phone numbers listed are the ones I called and the ones that told me I needed to contact the e-mail support for help.
So here I am looking for your help with my issue.
We just bought a new HP Pavillion Slimline Desk Top PC (as our 6 year old HP Pavillion PC died on us). We have 2 HP printers, one (an all-in-one type printer, used maily for copying and printing color, when needed) is connected and it is working fine with the exception of the scanning option (not supported by Windows 7). However we use our Laser Printer for all of our regular prining needs. This is the HP LaserPrinter 1200se, which is about 6 years old but works really well. For this printer we currently only have a parallel connection type cord and there is not a parallel port on the Slimline HP PC. The printer also has the option to connedt a USB cable (we do not currently have this type of cable).
We posed the following two questions:
1. Is the Laser Jet 1200se compatible with Windows 7?
and if this is the case
2. Can we purchase either a) a USC connection cord (generic or do we need a printer specific cord)? or b) is there there a printer cable converter adapater to attach to our parallel cable to convert to a USB connection?
We do not want to purchase the USB cable if Windows 7 will not accept the connection, or if doing this will harm the PC.
We really would appreciate any assitance that you might give us.
Thank you,
Randy and Leslie Gibson

Sorry, both cannot be enabled by design. That said, devices on a network do not care how others are connected. You can print from a wireless connection to a wired (Ethernet) printer and v/v.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

WRT310N: Help with DMZ/settings (firmware 1.0.09) for wired connection

Hello. I have a WRT310N and have been having a somewhat difficult time with my xbox 360's connection. I have forwarded all the necessary ports (53, 80, 88, 3074) for it to run, and tried changing MTU and what-not.
I don't know if I have DMZ setup incorrectly, or if it's my settings.
Setup as follows:
PCX2200 modem connected via ethernet to WRT310N.
The WRT310N has into ethernet port 1 a WAP54G, and then upstairs (so that my Mother's computer can get a strong signal) I have another WAP54G that I believe receives its signal from the downstairs 54G.
In the back of the WRT310N, I have my computer connected via ethernet port 3, and my Xbox 360 connected via ethernet port 4.
Now, I first figured I just have so many connections tied to the router and that is the reason for being so slow. However, when I unplug all the other ethernet cords and nothing is connected wirelessly, except for my Xbox connected to ethernet port 4, it is still poor. Also, with everything connected (WAP54G and other devices wirelessly) I get on my PC and run a speedtest. For the sake of advice, my speedtests I am running on my PC are (after 5 tests) averagely 8.5 Mbps download, and 1.00 Mbps upload, with a ping of 82ms.
Here is an image of the results:
http://www.speedtest.net][IMG]http://www.speedtest.net/result/721106714.png
Let me add a little more detail of my (192.168.1.1) settings for WRT310N.
For starters, my Father's IT guy at his workplace set up this WRT310N and WAP54G's. So some of these settings may be his doing. I just don't know which.
"Setup" as Auto-configurations DHCP. I've added my Xbox's IP address to the DHCP reservation the IP of 192.168.1.104. This has (from what I've noticed) stayed the same for days.
MTU: Auto, which stays at 1500 when I check under status.
Advanced Routing: NAT routing enabled, Dynamic Routing disabled.
Security: Disabled SPI firewall, UNchecked these: Filter Anonymous Internet Requests, Multicast, and Internet NAT redirection.
VPN passthrough: All 3 options are enabled (IPSec, PPTP, L2TP)
Access Restrictions: None.
Applications and Gaming: Single port forwarding has no entries. Port Range Forwarding I have the ports 53 UDP/TCP, 88 UDP, 3074 UDP/TCP, and 80 TCP forwarded to IP 192.168.1.104 enabled. (192.168.1.104 is the IP for my xbox connected via ethernet wired that is in DHCP reserved list)
Port Range Triggering: It does not allow me to change anything in this page.
DMZ: I have it Enabled. This is where I am a bit confused. It says "Source IP Address" and it has me select either "Any IP address" or to put entries to the XXX.XXX.XXX.XXX to XXX fields. I have selected use any IP address. Then the source IP area, it says "Destination:" I can do either "IP address: 192.168.1.XXX" or "MAC address:" Also, under MAC Address, it says DHCP Client Table and I went there and saw my Xbox under the DHCP client list (It shows up only when the Xbox is on) and selected it.
Under QoS: WMM Enabled, No acknowledgement disabled.
Internet Access Priority: Enabled. Upstream Bandwith I set it to Manual and put 6000 Kbps. I had it set on Auto before, but I changed it. I have no idea what to put there so I just put a higher number.
Then I added for Internet Access Priority a Medium Priority for Ethernet Port 4 (the port my xbox is plugged into).
Administration: Management: Web utility access: I have checked HTTP, unchecked HTTPS.
Web utility access via Wireless: Enabled. Remote Access: Disabled.
UPnp: Enabled.
Allow Users to Configure: Enabled.
Allow users to Disable Internet Access: Enabled.
Under Diagnostics, when I try and Ping test 192.168.1.104 (xbox when on and connected to LIVE), I get:
PING 192.168.1.104 (192.168.1.104): 24 data bytes
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Request timed out.
--- 192.168.1.104 data statistics ---
5 Packets transmitted, 0 Packets received, 100% Packet loss
Also, when I do Traceroute Test for my Xbox's IP, I just keep getting:
traceroute to 192.168.1.104 (192.168.1.104), 30 hops max, 40 byte packets
1 * * * 192.168.1.1 Request timed out.
2 * * * 192.168.1.1 Request timed out.
As for the Wireless Settings, it is all on the default settings with Wi-Fi Protected setup Enabled.
To add, I have tried connecting my modem directly to the Xbox and my connection is much improved. I have no difficulty getting the NAT open, for it seems my settings are working for that. Any help with these settings would be VERY much appreciated.

I own 2 of these routers (one is a spare) with the latest firmware and I have been having trouble with them for over a year. In my case the connection speed goes to a crawl and the only way to get it back is to disable the SPI firewall. Rebooting helps for a few minutes, but the problem returns. All of the other fixes recommended on these forums did not help. I found out the hard way that disabling the SPI Firewall also closes all open ports ignoring your port forwarding settings. If you have SPI Firewall disabled, you will never be able to ping your IP from an external address. Turn your SPI Firewall back on and test your Ping.

     }What I would like help with is the following
I would like output to either a JLabel or JTextArea to appear if a file appears on the network. Something along these lines
If file named nststrace*.* is in \\[network path] then output Download successful, please proceed.
btw I have done my best to search this forum for something similar and had no luck, but I am looking forward to Encephalopathics answer as he/she has consistently made me laugh with posted responses (in a good way).
Thanks in advance, Paul.

we're starting to get aquainted, but I think "best friend" could take a while as it is still as hard going as I recall, but I will persevere.Heh, it's not so bad! For example, if I had no idea how to test whether a file exists, I would just scan the big list of classes on the left for names that sound like they might include File operations. Hey look, File! Then I'd look at all of File's methods for something that tests whether it exists or not. Hey, exists! Then if I still couldn't figure out how to use it, I'd do a google search on that particular method.
