Why can't I load plugins from file system ?

Hello.
Why can't I load plugins from file system, fore development sake for ex. ?
Thx.
Andrew.

For security reasons, the Flash Player doesn't allow applications to access both the file system and the network.
One workaround is to compile the plugins in statically (rather than load them dynamically). The Akamai Plugin Sample shows you how to load plugins either way, you can see the source here: http://opensource.adobe.com/svn/opensource/osmf/trunk/apps/samples/plugins/AkamaiPluginSam ple/.

Dynamic load applet from File or MSSQL trigger

Hi,
i have an interesting project that i am researching, i would greatly appreciate if someone can point out some tools to use inorder to reach the following scenario with java.
I seeking to write data to a web applet whenever an insertion is done to a database or a new file is written to one directory on the server.
i need to display the information in the applet without refreshing any page.
i am very new to java, but i found that it could be done in a couple of ways....
1- Opening a channel between the applet and the server that uses HTTP request and response to load and update the applet without refreshing the page.
2-Programming a servlet on the server that communicates with the server and the client applet, it send the applet data when ever an insertion is done on the server.
3-Doing an applet that gets data from a cookie text file on the client machine, using an open channel between the server an the client the server writes these data to a certain directory on the client.
Please advice if any of these relates to the real world, and please provide tips of tools to do that.
Greatly appreciated,
Wafic

OK, lets see how to accomplish that... :-)
1- Opening a channel between the applet and the server
that uses HTTP request and response to load and update
the applet without refreshing the page.The idea of reloading the applet is not effective and leads to extreme performance losses.
But you can use a URLConnection to send requests and retrieve any data on that channel.
2-Programming a servlet on the server that
communicates with the server and the client applet, it
send the applet data when ever an insertion is done on
the server.Here is the tricky part.
To notify the applet you will have to set up some sort of server, as it does not know anything about operations on the web server side.
So you either set up a socket connection to the server or (better) use remote method invocation (RMI) to let the server call the appropriate method and immediately send the data.
This could be methods like (abstracted):
myApplet.getData(String fileData);
or
myApplet.notifyMe(); //triggers the HTTP request to get the data
This is also not so easy as you will have to start a RMI registry inside the applet.
3-Doing an applet that gets data from a cookie text
file on the client machine, using an open channel
between the server an the client the server writes
these data to a certain directory on the client.This is the part I do not understand.
Why are you sending a text file from the client to the server, which in turn should write the same file back in a client directory ?
Why not using the applet for that ?
Under any circumstances you will have to circumvent the applets security rectrictions on the client side by either signing it or deploying a policy file depending on the JAVA platform version you will be using.
I hope this helps any further.

Portege 3500 loads start up files but will not setup XP

When I purchased this 3500 it did not have an OS.
I managed to find a PCMCIA CD-Rom (thanks to this forum) which it will recognize the Windows XP CD.
This loads the Startup files but when we get to the Windows setup it closes the computer down requesting I look for virus and do a ch disk on the HDD.
I put the HDD in my other laptop and Windows seems to go into setup with no problems.
The HDD seems to have no problems.
This has bugged me for a couple of months now so any advice from anybody will be gratefully received.
Many thanks,
Martin

Hi again.
I've found something that might help you. It's not very easy but is should not prove too much of a problem either.
First go to this website : http://www.ultimatebootcd.com/ and download the latest build of the boot CD (which seems to be a very nice general tool by the way!).
Once downloaded, unpack it and burn the ISO-file to a blank CD Rom. You'll need a ISO-capable burning software to manage this (like Nero or other similar software).
Ok, so now you have the Ultimate Boot CD in your hand (hopefully).
Attach the external CD Rom to you P3500 and turn the P3500 on.
During the Toshiba-logo press ESC several times. You should get a message saying "Check system. Then press [F1] key."
If not - if the PC starts booting or display a boot failure message - just restart the machine and try again.
Now press the F1 key to enter the BIOS setup.
In the BIOS Setup, press HOME to set default settings, then press END to exit and confirm by pressing Y.
The machine will reboot.
When the TOSHIBA-logo is shown press F12-key a few times.
It should now stop with the boot device selection menue in the bottom.
If not - if the PC starts booting or display a boot failure message - just restart the machine and try again.
Make sure that the Boot CD is in the CD Rom and that the CD Rom is attached to your machine.
In the Boot device selection menue choose the icon that looks like a single disc (CD ROM). Get there by pressing the right or left arrows.
Mark your choice by pressing ENTER.
The machine should now boot from the boot CD Rom.
Once booted choose F6 - DOS/Linux boot disks
From the next menue choose F1 - FreeDOS boot disk
Next steps are a bit tricky because many choices you are provided are time-limited so you need to be quick - or like me, slow and have to do the same procedure over and over again to get it right.
Or! You can use the arrowkeys to abort the timer in the coloured menues! Nice to know when the limits are set really tight.
Choose no 1 from the menu which is default so if you don't choose here - it will be chosen for you.
Next you will be prompted with a kind of 'error' message that the software does not recognise the hardware (chipset). Just press ENTER.
Now the first coloured quiestion will pop up - do like described above if you need more time to think (like me) press the arrow-keys.
You can press Abort on the first one asking about ASPIUSB
Next one is important - CD-ROM.
Press Config.
In the menue that appears, choose Auto, try to detect all. Move around by using the TAB or arrow key and choose the item with SPACE.
The press Save - but you will get an error message since it is not possible to save this setting to the CD Rom. Don't worry, press OK.
Now press OK to run the CD Rom driver.
Next menue "ASPI"- press OK
Next menue "Keyboard" - press OK or press Config to pick another layout.
Next menue "DOSLFN" - Press OK
Next menue "NTFS Support" - Press OK
Last menue - Press OK
Now, finally! You have acess to both CD and HDD. The driveletters are shown at the bottom of the screen.
Next step is to insert the XP disc, copy the contents from the \i386 folder to a temp directory of the HDD and start the installation from that place.
Phew!
Good luck
Tom

Condition type for pricing came from PC but has not included the additive cost record

hello all;
we have the pricing base for the sales order with the estimated cost from pc; our costing process has a posting record for additive cost is not included on the total cost is sent to the condition type EK02.
question: It is possible to include these kind of postings?, in fact, these record apear on the costing report as part of the cost of sales..
thanks in advanced...

Hi Francisco
Two things,
1. Your condition type must be EK01 if you wanna use it in
Pricing
2. Additive cost in CK74 is at the level of material and plant. It is not at the level of sales order
If you wish to add costs manually in sales order cost estimate, then use Unit Costing as the costing method in your requirement class
Or use Product costing as costing method and use a costing sheet

Well i can load Class from file, but how i save it to file?

Hello,
Let's say we can load some Class using ClassLoader, but if i want to do the opposite? I would like to make a .class file, for this i have got Class object and few methods.
the start would look like this;
Class<?> cl = ....;
String nameWithPackages = cl.getName().replaceAll("\\.", "/")+".class"
File file = new File(nameWithPackages);
... Well now i need to fill the class file with the data, any ideas?
Thanks

I made a Blurb book through Lightroom 5, on another computer, backed it up on an external hard drive and tried to import it into my imac. I got the picture files, but could not get the book I had worked on. How do I find my book?

I made a 'Blurb' book using Lightroom on a computer that was not mine. I backed up the book on an external hard drive and then tried to import the book into my imac. I wasn't able to retrieve my book. The photos I used for the book project are there, but the 45 page book I made is not there.
What do I need to do?

You would need to go to the computer containing the book.
Select the saved book in the Collection panel.
Go to Grid View [ G ] and select all the images [Cmd/Ctrl][A]

It should bring the images, your collections (including your book) and other settings into your own catalog.

Glad I could help. I recommend you look into using FindBugs, it will warn you of this kind of thing. Also change the way you open/close streams to:
YourStream stream = null;
try {
   stream = new YourStream();
   // read/write from
} finally {
try {
     stream.close();
} catch( IOException ioe ) {
      // Log the IOE. Or use the IOUtils.quiteClose from Commons IO.
}As otherwise you could leave the stream open, i.e. if the read() method throws an IOE.

You need Lightroom 5.5 or later (the most current version is 5.7.1). This is a free update if you have already purchased an earlier version of Lightroom 5.

Can load image from file using LabVIEW and display on IMAQ graph?

I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?
Thanks!

Hey werwr,
In response to: "I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?"
As of right now, in order to read an image from file, you actually do need the IMAQ Vision software. The IMAQ driver without the Vision VI's will allow you to collect images from a framegrabber, and it will allow you to save those images to file. But the function that allows you to read an image from file does require the Vision VI's. Once you have the VI to read images from a file, you will be able to display the image on an IMAQ "Graph" or otherwise known as an Image Display.
I hope this helps. Please let me know if you have any further questions.
Thanks,

Using srw to load graphics from file in different path

Hi all,
I work with report 6i and I want to build a report with dynamic graphics. I stored the file name and directory in field of my data base.
I want to know if it is possible to load graphics in report with package srw. If it is possible, can you tell me how can I proceed?
best regard.

Not sure if this option is available in reports 6i, but in reports help contents search for:
'read from file'
In data model get the database field having image path. In report layout, open property inspector of this field and change property 'Read from File' from No to Yes and also change property 'File Format'.

I started using JasperReports for my web application report generation. I'm using JSPs for web development.
I created a .jrxml file using iReport and used the following code to generate the report.

          JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

Anyone pls help. It's bit urgent. Thanks.

I was using iReport v0.5.0 and it uses jasperreports-0.6.7.jar (v0.6.7) of
JasperReports. I compiled and i deployed my application in BEA weblogic server. I got the error listed below. Only after i saw your
response explaining that iReport was the issue, i checked the iReport lib directory and found this version of jasperreport jar.
iReport creates a java source file which is used to a jasper file.
iReport will link in the v0.6.7 version of jasperReports. When you
deploy your web application it will recognize this version through the compiled jasper file and give you the InvalidClassException, even
though you only have one jasperReport jar deployed with your war file.
The way i fixed this problem was to create my web application with the
jasperreport jar comes with iReport.
Thanks for mentioning iReport.
Christopher
