EntityBean generation

Can anyone provide me link for generating template entity bean using eclipse?
I am using eclipse 3.3, weblogic 10.3, oracle 11g.
I read in article after creating table in database using eclipse entity bean can be created from table. i checked this but i am able to generate only one file(table-name.java.)
What about other files,may be i am doing me some wrong steps .

Refere to the following threads
1. http://forum.java.sun.com/thread.jsp?thread=345523&forum=13&message=1428251
2. http://forum.java.sun.com/thread.jsp?thread=345256&forum=13&message=1426543

Cluster DuplicateKeyExecption and primary key generation

Hi
I have 2 applications servers working in a cluster.
I'm using for primary key generation The pattern "sequence blocks" taken from the book ejb design patterns.
However when i have something like 5 threads that are trying to create new entities then i get DuplikateKeyException on the primary key. (with only 1 jboss server not in a cluster everything is fine).
I was wondering if anybody could help me pin out the problem, following is my code:
I estimated it might be an Isolation level problem, however i have updated the isolation level to be serializable in that way in mysql ds and the problem still happend...

Open vi error for report generation toolkt

Originally it works fine.
Now I upgrade to win7, LV9 and office2010.
To open the old program by 8.6.1, I reinstalled LV 8.6.1 and report generation toolkit.
But still got the error as attached.
Any suggestion, thanks.

1. MS Office 2010 is not yet supported, since it's still just a beta. I believe there are couple of changes that Microsoft make, and it could cause a problem.
2. LabVIEW 8.6.1, and all its toolkit is not supported on Windows 7. This could cause a problkem also.
In conclusion, you should use LabVIEW 2009, Report Generation Toolkit 2009, Windows 7, and downgrade office to XP, 2003 or 2007.

1st Generation iPod Touch No Longer Recognized by Windows 7 PC

I have a 1st generation iPod Touch (no camera) that can no longer connect to my Windows 7 pc. Plugging in the iPod via USB does not trigger any sort of dialog box in Windows and it doesn't trigger a message saying a device has been connected; the iPod does not show up in either iTunes, Computer, Device Manager or Devices and Printers, either as an Apple mobile device or an unrecognized device, and does not charge when connected to USB (though the wall-charger still works). As far as my computer is concerned this iPod does not exist. I had successfully synced this iPod as recently as one week ago and am ready to pitch the thing in the garbage if I can't find a solution.
I have the latest version of iTunes as well as the most up-to-date Windows updates. I have already followed all the steps listed here (iOS: Device not recognized in iTunes for Windows) multiple times with no success.
I also have tried following the instructions listed here (Re: For those Windows users who suddenly cannot see their device in iTunes. Here's a solution that has worked.) but this also hasn't worked since the iPod isn't recognized in the Device Manager and I am not given the option of updating the drivers, manually or otherwise.
I have uninstalled/re-installed iTunes and all related Apple services multiple times. The Apple Mobile Device Service is functioning normally. iTunes diagnostics indicate that there is no device connected no matter what I do. I have reinstalled my Windows USB drivers and changed the settings on the USB Root Hub in the Windows Device Manager to disable power saving options.
I have tried connecting the device to another PC which detects and syncs another apple device (iPhone 5) with no issues, and had the exact same result: the computer doesn't even recognize an iPod is connected.
I can't update the Apple Mobile Device Drivers because the device is not recognized by my machine in any way.
I even completely reset my iPod and that just left me with a unactivated iPod that still isn't detected.
I am really unbelievably fed-up with the useless "try checking your USB cable"-style advice that people seem to offer on this forum. If anybody has dealt with this issue and has any serious advice other than "re-install iTunes," it would be much appreciated.

You said "I am really unbelievably fed-up with the useless "try checking your USB cable"-style"
- Did you try another cable?
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.

Issue with PTO (Paid Time Off) quota generation

Hi All,
We have an issue with quota generation of PTO for our employees.
The issue goes like this:
We have a Paid time off for employees 5weeks( 200 hrs) for employees who have worked less than 5 years.
we have paid time off for employees 6 weeks ( 240 hrs) for employees who have worked more than 5 years.
we have the following logic that has to go in this config:
-- Our fiscal year starts on Feb 1st and ends on Jan end or Feb starts which has a full week of working days. ( ex: if 01/31/2012 falls on a Thursday the following Monday which has full 5 day working week would be the end of the fiscal year).
-- Depending on the working hours of the employees and the date of joining for the first year ( for new hires)0041 info type the eligibility gets varied and reduced. Ex( employees who joins on start of fiscal year and works 40hrs per week schedules is eligible for 200hrs of PTO. Employees who join in the month of august and works for 35 hrs per week ( i.e mid of fiscal year) would get 91 hrs of PTO.
I need to put this in the system. I am thinking this could be done with out tweaking PCR.I need help in configuring this in Absence quotas as to what are the things i need change in system config and how do i do it. Please help with some screen shots if possible. I really need this to get it done ASAP. Looking forward for help.
Thanks,
Chowdary.

We use TM00 schema. Can i call TS15 and TS 12 rules into TM00 acheieve my issue of quota entilements?
Iam doing this because my businees needs to see if an employee chages his work schedule from 40 to 30 or 20 etc.. the PTO has to vary accordingly.
As the minimum eligibility is to work for 20 hrs to avail the PTO days. If at any point the employee drops it under 20 he will not be eligible till he work any this >= 20hrs per month so the evaluation has to check periodically to update the quota availability.... I need help plz suggest ...

Report generation toolkit and signal express user step : problem of closing reference in "Stop" event

Hi all,
I'm trying to make a package of Vis to easily make Excel reports with Signal Express. I'm working on LabVIEW 8.2.1.
I'm using the report generation toolkit, so I build a .llb from my project which contains all the hierarchy of my steps, but also the hierarchy of dynamic VIs called.
I have made some steps, like "Open Workbook", "Write Data", etc.
My steps run well, excepts one step : "Close Workbook".
If my "Close Workbook" step is firing on "Run" Signal Express event, I have no error, so my reference is properly closed.
But if my "Close Workbook" step is firing on "Stop" Signal Express event, I have an error "1", from "Generate Report Objectrepository.vi".
I feel that I'm trying to use a reference which has been killed in the "Stop" step...
I would like to know what exactly do Signal Express on "Stop" event and why my close function does'nt run well.
Thanks,
Callahan

Hi Callahan,
SignalExpress (SE for short) does the following on the Stop event:
1. Takes the list of parameters that SE found on your VI's connector pane, and sets the values that the user set from the "Run LabVIEW VI" configuration page, if any.
2. Then tells the VI that SE is running the Stop event by setting the Enum found on your VI's front panel. This in turn should produce some boolean values telling your VI to execute the Stop case.
3. The VI is then run, with those values and states.
4. SE checks to see if any errors where returned.
5. Since this is the Stop event, SE releases the reference to the VI which it possesses.
Questions for you would be, is the reference to your Workbook linked to a control on your connector pane, or held in a uninitialized Shift Register. If it's held in a Shift Register, SE would not be aware of it, and would not be able to affect that reference.
Hope that helps. Feel free to post your LLB if it doesn't.

Report Generation: New Report.vi

Running applicaion in development mode works fine.
After compiling however I get Error 7: Open VI Reference in New Report.vi
Why am I getting this error?

Has the version of Office on your machine changed since you installed the Report Generation Toolkit? The VIs will become broken if the ActiveX interface changes, and this can happen when the Office version changes. I recommend uninstalling and reinstalling the toolkit. Also, what version of Report Generation Toolkit are you using? The latest version is 1.1.1.

P.S. - I'm going to respond to your other thread that you started with a link to this one. Instead of creating multiple messages on the same question, just wait for a response to your initial thread.

Report Generation Toolkit Error (undefined erro)

Does anybody know what error -214 682 7864 (0x800A01A8) means when coming from the Report Generation Toolkit.
I have an app which has been happily ticking over for several weeks, and then this error was generated when attempting to write a table to a spreadsheet. The error was generated all the way down in NIReportGenerationToolkit.lvlib:Excel_Get_range.vi (this is the ActiveX code).
Any ideas?

Was it the first time you attempted to write the table to that spreadsheet?
Maybe the error is due to the spreadsheet grown oversize than its limit so that it cant accomodate the table anymore.
What is the version of MS Office you are using? I think Office 2003 can go only upto 1024 columns...

Report Generation Exe Error

Hello,
I am using LV 8.6.1 with the 1.13 report generation toolkit and I am having problems getting my built exe to work. I am trying to open an excel template and populate it with new data. I have broke the vi down to just opening excel - opening the template and then fill in some data. But at this point excel does not open at all. And naturally everything works fine in the development environment.
Error Code: -2147352573
Member not found in NI_ReportgenerationToolkit.lvlib:
Excel_open_workbook.vi
NI_Excel.lvclass: new reportsubvi.vi
I read a few help pages that said to add \vi.lib\utility\NIreport.llb and LVclass directories to the project folder and add them to the always include section of the build. But no luck so far.
Side question: The machine I want to use this on has 8.6.1 Full which does not have the extra excel functions that my developer has. Is there a way to install the DEV report generation toolkit in the full version? Then I would not need to build an exe.
UPDATE: I just tried the exe on a different machine that has a developer suite installed and it worked fine. So I guess I need to find out what else I need to add to the build to make it work.

There should be some info on this in the KB.
But first you should make sure that your version of the report generation toolkit actually supports excel 2000 (which is 10 years old)
That should be in the release notes of the toolkit

Report-generation vi problem

On a Windows XP system using the "Text Report Example" vi, the (read) report property node item "TextFont" (stdole.Font) at the beginning of the "Font Style" vi which is a part of the "Set Report Font" vi is returning this error:
"-1073741819 Unknown System Error in Font Style.vi->Set Report Font.vi->Easy Text Report.vi"
Any suggestions as to a cause and cure?

This Knowledge Base from NI's website actually deals with this problem. The fix depends upon whether or not you have the Report Generation Toolkit for LabVIEW. There are fixes for whether or not you have the Toolkit. Hope this helps.

Report Generation for Excel does not work after using the Application Builder

I have a VI that writes data to an Excel file using the Report Generation Toolkit. I recently compiled the VI into a single Application (EXE) using the Application Builder. My VI runs its tests properly, but no data is written to Excel. What could be the cause? I don't receive any error messages.

Hi
I usually build exe-files, which sometimes also have report functionality.
Open the Application Builder and check the following things:
1. Add the following vis: _Word Dynamic VIs.vi, _Excel Dynamic VIs.vi They should be located in the directory ..\LabVIEW X.X\vi.lib\addons\_office in the llbs _wordsub.llb and _exclsub.llb (report1.jpg)
2. If you use an Installer, go to the Advanced Settings. There you can select some things to include in the Installer. Check if "NI Reports Support" is selected. (report2.jpg)
These are the things I always do, if I need reports and I never had problems up to now. I made two screen-shots of these settings.
Hope this helps.

Report Generation Toolkit producing error -2147417842, "The application called an interface that was marshalled for a different thread."

Hi everybody,
I've got an application that logs data to an Excel spreadsheet using the Report Generation Toolkit. My VI's have worked fine in the past using Excel XP, but since I've upgraded to Excel 2007, I am getting COM errors like this one:
"Error -2147417842 occurred at The application called an interface that was marshalled for a different thread. in Excel_Insert_Text.vi" That is the exact wording, even with the weird punctuation and capitalization.
The first occurrence of the error is not determinate. Sometimes, up to 10 logging sessions, involving a new .xls file, can occur before this error pops up. Once this error occurs, I must quit LabVIEW to resolve it. If I try to do anything with Excel, I always get this error, although sometimes it comes out of different source VIs. Excel_Open.vi is another.
These logging VIs have worked just fine until upgrading to Excel 2007. I checked, and I was using a really old version of the Report Generation Toolkit, v1.0.1. I read the documentation and had a big sigh of relief when I realized I needed to upgraded to v1.1.2 to get Excel 2007 support. However, even after upgrading, I'm still getting the same errors. I'm using LabVIEW 8.0.1, and I'm also building these VIs into an application. The error occurs both in the LabVIEW IDE and in the built application. Does anybody out there have any idea what I can do to fix this? I googled a little, and discovered this is a COM error, but I can't find any references to the Report Generation Toolkit specifically.
Thanks,
Phil

Hi Christian,
I do not see that exact option listed, do you mean "user interface"? I recognize the "Run in UI Thread" option, it's on the Call Library Function Node.
I checked, and my top-level VI has "same as caller" set, and I believe all my VIs are set to "same as caller". Are you suggesting I change my top-level VI preferred execution environment to "user interface", or just the logging sub-VIs that use the Report Generation Toolkit?
Thanks,
Phil

Report generation toolkit VI error when running EXE

A VI inside the Report Generation Toolkit (version 1.1.2), Excel Find Application Directory.vi, will not function correctly when running an EXE. The "Current VI's path" block will return the path of the currently running EXE rather than the path of the Excel Find Application Directory VI. (The same would be true for Word Find Application Directory.vi.)

Have you had a look at this knowledgebase article? The error is caused due to the exclusion of any dynamic VI.
