Typo in document System.getProperty
fileconn.dir.MemoryCard.Video must bes fileconn.dir.memorycard.video instead. The former will throw an exception.
Thanks for the find! I will get this update soon.
See you soon,.

Problems capturing pictures about OS6 - East System.getProperty ("video.snapshot.encodings"); valid?
Hello
I hope someone can help with this query.
I use the code that is very similar to the sample application camerademo to take a photo using the camera. It works properly on devices running OS5. However, on devices running OS6 photo is just an image of white/black.
I think I followed the problem until the encoding string passed to getSnapshot(). When I switch which must be a valid encoding string (based on the output of System.getProperty ("video.snapshot.encodings")) the captured image is a black screen. However, when I pass null to getSnapshot() it works correctly. I want to avoid using null as the captured image is much more that I need and for reasons of effectiveness, I would like to avoid having to reduce its size after the capture of the photo.
I tested this on the 9780 Simulator. The corresponding code is included below for reference.
Thanks in advance!

It turns out that it was only a problem on the Simulator. I managed to get my hands on a real device 9780 and the code works fine on it.

System.getProperty returns NULL on Simulator
The following call:
System.getProperty("video.snapshot.encodings")Returns a null value.
I tried using the default Simulator of the component package 4.5.0_4.5.0.16.
This key is available in 4.7 +. I don't know what you're trying to do, but you should know that there is no way to adjust the front camera of 4.6.

I'm trying to access the SD card on the Simulator.
I first 'change' SD card via the Simulation menu and specify a path name, that I have set up to be identical to the structure of the directory of the SD card.
Then, something I just found out, is that I have to get the name of the SD card.
System.getProperty tried to get the name of the root directory, and I got the following results.
The key string result
filecon.dir.MemoryCard null
filecon.dir.MemoryCard.Name null
Why do I get null for the name of the name of the SD card?
How to open a file on an SD card on the Simulator is - a. Is there anything else I need to put in place on the Simulator in addition to change SD card.
.. .where is this result telling me that the way to access the Blackberry directory on the SD card is to use the following:
file:///BlackBerry/
that is the SD card has no name... null?
Thank you
-Donald
I solved this myself (at least this part :-)
OK, for those of you who want to know how to open your media card correctly (at least in the storm).
First, make a call to System.getProperty ("fileconn.dir.memorycard");
This returns the string "file:///SDCard/".
Note that you are not guaranteed that the file system of the media card will always be SD card, so you should always call System.getProperty beforehand.
Then, if you use the Simulator, you must select the simulate change... SD card menu. This opens a small window allowing you to select different directories (by default is set to None, which means the media card is disconnected). You can click new folder to set the directory that emulates the directory root of the press card. You can enter several directories and it will remember them so you can switch from one to the other. The entry selected (highlighted) is used, so if you select none, it generates an event to remove media card.
You must also set the it strategy using strategy-simulation game IT... menu.
Under the tab control application, you must assign to allow local connections and all the other features that you will use. Similarly, the policy of COMPUTER you must select allow local connections and click on him-> the button to add to the list of policies. Also you must click on the set after that to define the it strategy.
OK, now you can open the connection to the file.

Java 7 u45 System.getProperty returns null

with old java version, System.getProperty ("myproperty") works very well to return the value, but with u45 it returns null.
Does anyone have the same problem? no idea how to fix or work around it?
Thank you
Zhongyao
7u45 made a change that is not documented in the release notes. You must precede the properties with jnlp.myproperty in your JNLP file, unless your jnlp file is signed.
But like me, since you can have different values in multiple deployments, signing the JNLP is impossible.
I tried to submit a bug on this issue report, but their bug report process works as well as 7u45...

Can not read the Oracle JVM system property unless the class is reloaded
I want to be able to read system properties set of
DBMS_JAVA.set_property of a java stored procedure. To do this, I have this simple code:public static String getEnvironmentVar(String propertyName) { return System.getProperty(propertyName); }When I run the present on the database, java stored procedure does not seem to load the property just has
DBMS_JAVA.set_property:declare s varchar2(100); begin s := dbms_java.set_property('test_prop', 'test_val'); s := getEnvironmentVar('test_prop'); -- This is my java stored proc dbms_output.put_line(s); end;However, when I reload the class in Oracle (with loadjava); the property is read correctly. Am I missing something?
Thank you.
If you try the declare in a new session of RDBMS, I think you'll find that it works. Or insert the line
s: = dbms_java.endsession;
between the dbms_java.set_property and the getEnvironmentVar call. When dbms_java.set_property is called, it creates a value for a property that is used only for subsequent initializations of the java VM for this session of RDBMS. It does not affect the java VM that has already been initialized in the session, as appropriate. If java has not been used before that in the session underway, then the virtual machine will be initialized when the getEnvironmentVar call is made and the value established earlier by dbms_java.set_property discussed. But if java had already been used in the session, such as would happen if you had previously created or solved the class containing the method getEnvironmentVar of the session, then the value set by dbms_java.set_property is not visible (unless and until that something (like dbms_java.endsession, System.exit or an unrecoverable error) occurs to put an end to the existing java VM without end of the RDBMS session).

How to set up a system property
Hello world
Does anyone know how to set up a system console for WebLogic 11 g property?
I´d as set up a property via the web console, then get this property in my java code. Something like this:
System.getProperty ("foo");
Is this possible?
Thank you
FernandoHi Fernando,
Please see the link which tells us how we can define the JAVA_OPTIONS the administration Console...
http://WebLogic-wonders.com/WebLogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/
The link above demonstrate that how we define * "-the system Duser.dir property = E: / MyDirectory" *...Now you can set your own JAVA_OPTION as follows:
-Dfoo = MyFooValue
After setting above propertu in AdminConsole MEM ARGS, you must restart the server. Then, you can use the following code:
String result = System.getProperty ("foo");
.

Thank you

Problem call System.loadLibrary () in JRockit JVM for Solaris (Solaris OS) Vs
Hello
I try to transfer my code running under Sun JDK 6 in Jrockit (R28).
However, I am facing a problem of loading a library ('so') under JRockit which works very well under the Sun JVM.
The LD_LIBRARY_PATH setting is identical for the two JAVA VMs.
I wrote a class simpel, loading the library (in a file called libDiskCapacityUnix.so, located in/usr/mms/common/lib) just to test this device under two virtual machines Java is the code in the class:
public class MyClass {}
Public Shared Sub main (String [] args) {}
Path String is System.getProperty ("java.library.path");.
System.out.println ("Java.Library.Path =" + path);
System.loadLibrary ("DiskCapacityUnix");
System.out.println ("loading library DiskCapacityUnix succeeded");

Migrating from JBoss to WebLogic 10.3: how to set the system property?
Hello
I am migrating from JBoss to WebLogic, and I need to define a global property.
What I need to do, is to link my path of the properties file for a global property accessible to all applications deployed on the server, in order to find the path of my applications (EJB 2.1) and access the properties without cutting the path of the properties file in the code.
In jboss, I used the file "properties - service.xml", in which I can set the key/value pairs, and the key will be published to the server and available programmatically as a property system through the call "System.getProperty ().
How can I do the same in weblogic 10.3?
Thank you!Yes
In both options... .reading the code in the file property will be the same.
Thank you

How can I get the UserAgent from my BlackBerry?
I want to get the UserAgent of the blackberry where my application is running. How do I remove this?
You cannot retrieve the user agent itself, but you can get some information for you to assemble and generate the user agent. I've already tested and it's the same as the user-agent sent by the RIM Browser.you can also make reference to this document.
You can use this one.
String userAgent = return "BlackBerry" + DeviceInfo.getDeviceName () + ' / ' +.
DeviceInfo.getSoftwareVersion () +.
"' Profile /" + System.getProperty ("microedition.profiles") + "
"Configuration /" + System.getProperty)

Bidi text JTextPane and JTextArea changes the row height
You can use the following example to demonstrate the problem. When you run, copy and paste an Arab character of http://www.alanwood.net/unicode/arabic.html in the display area. This creates a condition of bidi in the document. The circumflex replaces one with a flag at the top to indicate ownership LTR or RTL of the character. The height of the display line, going at a lower height. I am able to detect the State of bidi. I can't get any action to indicate what was the change of line height. I've exhausted all measuring height of possible line that I could find. The size reported by all methods does not State non-bidi bidi State, even if the row height is significantly reduced. Anyone else encounter this? Any proven way to measure the difference?

}I think that Eclipse does not use JEditorPane but own component. GUI editors has monospaced fonts of equal width/height for each tank and fixed a height for all rows. It is much easier to manage several sizes of fonts on the same line.

Make sure:
(1) refer to your bean (implementation class) as: oracle.forms.fd.AppletInfos
(2) use the get_custom_property built-in for your info:
For example:
: B1. MAC: = Get_Custom_Property (' B1.) TEXTAREA', 1, 'MAC');
: B1. DIP: = Get_Custom_Property (' B1.) TEXTAREA', 1, 'DIP');
Please note that there is a property GETINFOS that was not declared in your code and added. You can change it if you wish.
(3) you must sign your jar file. Check the webutil on your developer installation directory for an example.Hafed
