get error below when running the code above through driving the demand, but he worked for 1 print the line, but when it's on a loop, it throws this error.
The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.
I came across the same thing as you. I did a lot of experimenting and found it works:
var result = (function() {
var ReflectiveArray = java.lang.reflect.Array;
var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;
var columns = ReflectiveArray.newInstance(java.lang.Object, 1 /* number of selected columns */);
var results = [];
SQL = CreateSQL("SELECT OPRDEFNDESC FROM PSOPRDEFN WHERE ROWNUM < 10");
while (SQL.Fetch(columns)) {
results.push(columns[0]);
}
return results.join();
}());
He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].
Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:
columns[0] = null;

the menu item run method not called
Eclipse SDK Version: 3.4.1

I added a menu item to the contacts list. I would like to get the context when the user clicks the menu item, but the run method is not entered. When the user clicks the item in the menu the main routine is entered with correct arguments. Should not called run with the context method? No exception is thrown.

e.printStackTrace ();
}
Returns a null value.
}
}
}You call system.exit() in the Builder before entering the EventDispatcher. I'm guessing that you add the menu item, but leave the application, and when the menu item is called it is more a reference to the context of the application and decides not to continue. The menu item will not remove itself when the application closes.

Therefore I don't see the placeholder to correct the link. How can I fix this, or at least manage the display of the placeholder.
Concerning
I don't think the resources without the dDocName specification will work (for example [!-$wcmUrl ('resource', ")-]).
At some point, the code path probably leaves the SiteStudio component and goes back to the core code WebCenter content to fetch the revision. It seems that it is where he meets a problem (impossible to find the last out for review).
If you turn on additional detailed complete tracking for site *, file * and system * this gives you a clues?

The use of reflectors to dynamically call objects

----------------------------------------------------------------The following is the only difference with the code of yours and mine, and it does not work for me.
fuego.papi.Arguments args = fuego.papi.Arguments.create ();
args = papisession.activityPrepare (activity, instanceId, args);Note that I don't have another object to restultArgs you. Not sure if this should make a difference.
Second, the arguments that I have nothing in it. For you, there is an argument in this object, which is var1 = dyn. I guess that since there is no argument in your prepare method entry mode, this variable could not be transmitted to the prepareMethod. (Just a guess)Here's my understanding:
prepareMethod is used to pass arguments of BPM for external application. So, you can define arguments of prepareMethod as arguments of mode 'out '. These arguments are defined in 'args' when you call "args = papisession.activityPrepare (activity, instanceId, args); The external application can then perform a treatment based on them and later call commit and go back a few arguments to BPM.May be worth trying another

Java Script alert: MuseJSAssert: error calling the function switch: security error?
Hello
I built a site of Muse and place a dashboard project animate the site. Here's the problem I have. When I saw in the browser through Muse all seem to work well. The problem is when I export to HTML. When I view the HTML file in Firefox, everything works fine. But when I discover the HTML in Chrome or Opera, I get the following error appears on the top of the browser: Java Script Alert: MuseJSAssert: error calling the function switch: security error: blocked a frame with original "null" access to a framework of cross-origin.
Any ideas what is the cause? I noticed one thing, but if I click the button refresn the animation playback. The other thing I noticed, is that my full screen lide show is also affected by this error. He plays as the first image and the rest of the images are not displayed.
Thank you for any suggestions to fix this.
Hey all!
I finally found how to solve this problem! At only took about 3 hours!
Therefore, to do with the iframe code muse did for the lively edge file.
If we take things from the outset, if everyone includes:
1 publish a 'edge Animate Deployment Package (.oam)' dashboard animate
2. in muse, file > Place > {exported .oem)
3. put the file where you want
4 muse export as HTML (file > export as HTML)
5. your browser will open and display the error message, as shown above
6 locate the HTML files and find "index.hml", or the page that your file hosted dashboard is on
7. open it in Notepad, or editing program code. I use Adobe Edge Code CC
8 remove the text: class = "animationContainer an_invi" (press ctrl + f and type to find the line)
9 be sure to save and then reopen the Web page!

no response on java windows in oracle command call
Hi, experts.
I try to get the free space on my disk of database.
I had the test in several ways without success. It's the last one I tried. I create a JAVA SOURCE of oracle who calls Runtime.getRuntime () .exec () in java.
The code is:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED TEST.DISKS_FREE as import java.io.IOException; import java.io.InputStreamReader; import java.io.BufferedReader; public class diskfreespace { public static String loaddisk() throws IOException,InterruptedException { //Process p=Runtime.getRuntime().exec("cmd.exe /c wmic /node:\"%COMPUTERNAME%\" LogicalDisk Where DriveType=\"3\" Get DeviceID,FreeSpace|find /I \":\""); Process p=Runtime.getRuntime().exec("cmd /c dir|find \"bytes free\""); //Process p=Runtime.getRuntime().exec("cmd /c dir"); //p.waitFor(); BufferedReader reader=new BufferedReader( new InputStreamReader(p.getInputStream()) ); String line; String result =""; while((line = reader.readLine()) != null) { result+="\n"+line; } return result; } }As you can see, this method calls to order
cmd.exe /c dir|find "bytes free". In the java runtime environment, copy the following code works perfectly, backC: 13741621248, but in oracle, it should never send a response. I tried with other ordercmd /c dirlist of directories for both cases.Any idea?
Kind regards.
Do you want only it with only JAVA? Or any other approach will suffice to your goal? You can use the preprocessor to external table feature to achieve the same. I don't have Windows, Linux system, I'm going to show, but the same thing can be implemented in Windows with minimal changes.

[java rmi] PortableRemoteObject method not referenced
Hello everyone.
I use a portable proxy between an IIOP client and server of connection JRMI (activated). While the proxy has an active reference on the login server, it cannot execute his method not referenced. So I try to use the source not cited in the proxy too, but once he gets a reference to the login server (the first time a user IIOP calls the PortableProxy.login () method, the replacement no quoted source method is never called.
It's my proxy code:
I closed all the user jvm, but nothing happened. I don't have a reference to the proxy each time, I put it to null.public class PortableProxy extends ClientAuthentication, Unreferenced{ private String path = System.getenv("WORKDIR"); private ClientAuthentication authLogin = null; private static final String authServer = "authServer"; private static final int authServerPort = 1098; private static final String authServerIP = "localhost"; private static final int portableProxyRMI = 3500; private static final String portableProxy = "PortableProxy"; /** * PortableProxy() */ public PortableProxy(){ Properties prop = new Properties(); Object obj = null; System.setProperty("javax.net.ssl.trustStore",""+path+"client/mySrvKeystore"); System.setProperty("javax.net.ssl.trustStorePassword", "123456"); try{ PortableRemoteObject.exportObject(this); System.setProperty("java.rmi.dgc.leaseValue", "12000"); System.setProperty("java.rmi.dgc.checkInterval", "6000"); }catch(RemoteException re){ System.out.println("PortableProxy.PortableProxy() RemoteException: "+re.getMessage()); re.printStackTrace(); } System.out.println("PortableProxy exported"); } /** * lookRef() */ public void lookRef(){ Properties prop = new Properties(); Object obj = null; prop.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.rmi.registry.RegistryContextFactory"); prop.put(Context.PROVIDER_URL, "rmi://"+authServerIP+":"+authServerPort); InitialContext ic = null; try{ ic = new InitialContext(prop); obj = ic.lookup(authServer); }catch(NamingException ne){ System.out.println("PortableProxy.lookRef() NamingException: "+ne.getMessage()); ne.printStackTrace(); } authLogin = (ClientAuthentication) PortableRemoteObject.narrow(obj, ClientAuthentication.class); } /** * login() */ public Runnable login(String user, String password){ System.out.println("Sono in PortableProxy.login()"); Runnable ret = null; if(authLogin == null){ lookRef(); } try{ ret = authLogin.login(user, password); }catch(RemoteException re){ System.out.println("PortableProxy.login() RemoteException: "+re.getMessage()); re.printStackTrace(); } return ret; } /** * unreferenced() */ public void unreferenced(){ authLogin = null; if(authLogin == null){ System.out.println("authLogin = null"); }else{ System.out.println("Something went wrong: authLogin != null."); } System.gc(); } /** * MAIN */ public static void main(String[] args){ Properties prop = new Properties(); PortableProxy proxy = new PortableProxy(); prop.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory"); prop.put("java.naming.provider.url", "iiop://localhost:"+portableProxyRMI); try{ InitialContext icProxy = new InitialContext(prop); icProxy.rebind(portableProxy, proxy); }catch(NamingException ne){ System.out.println("PortableProxy.main() NamingException: "+ne.getMessage()); ne.printStackTrace(); } } }
Where I am doing wrong?
PS: I also want to set the leaseValue and the checkInterval for a shorter time. In this way (under the PortableRemoteObject.exportObject (()) the right way?
Tell me thanks in advance, if you need additional information. Thank youIn my view, that the unreferenced support is available only when the use standard rmi. the iiop based RPC does not support distributed gc.

Apply the variable definition in the subclass with abstract method
Hello
It's his practice use? :
I want to apply the extension of the class to define a private variable, but there is no variable abstract in java, I can use a method for that.public abstract class Base { private int importantPrivateVariable = setImportantPrivateVariable(); protected abstract int setImportantPrivateVariable(); }
Thank you
lemonboston
Edit: the variable can be protected as well, I guess that's not important here, but correct me if I'm wronglemonboston wrote:
HelloIt's his practice use? :
I don't think it's so common, but it's easily understandable code. However, there are several problems with this approach:
public abstract class Base { private int importantPrivateVariable = setImportantPrivateVariable(); protected abstract int setImportantPrivateVariable(); }I want to apply the extension of the class to define a private variable
This is some what your code implements: your base class requires the subclasses to return an int value, and the Base class uses this value to assign to the variable.
Therefore, the method should be called to
Edit: the variable can be protected as well, I guess that's not important here.
Well, Yes, it is 'important' - at least, there is a noticeable difference: the variable is private, the base class is free to treat it as seems it (for example, assign the value at construction time and never change it later). If the variable was protected, the subclass could change in ways and at times not known by the base class.
but correct me if I'm wrong
There is a trap in this construction: the method is called in the variable initializer, i.e., behind the scenes, about during execution of the Base, so before the constructor of the sub-class class constructor. For example, you call a method on an object that is not completely initialized (for example some of its attributes may always be null at this point). There is a rule that discourages this kind of situation, which goes something like "no calling private and unofficial constructor methods.
To avoid this trap, two options:
-requires an int argument in the constructor of the Base class, as suggested above
-Don't be and set the value of the important variable in the code of the initializer or the constructor, but a special method in the base class instead:public abstract class Base { private int importantPrivateVariable; // default value is zero // or alternatively: // private int importantPrivateVariable = ...; // Some default value protected abstract int getImportantPrivateVariable(); public void initializeImportantPrivateVariable() { importantPrivateVariable = getImportantPrivateVariable(); } }This construction is a degenerate form of a common model known as the model method (where a base class method calls usually several methods of the subclass in a specified order and with a specified sequence, allowing for the subclass to implement the details of the methods).
The downside is that the client code (the one that uses the Base instance) must know when to call this initialization method, while initialization, a constructor-based allows the free client code of don't like do not at all.
Much luck,
J.

which method is called when the screen has lost focus but stays on blackberry?

I want to know in which method is called when the screen has lost focus, but always visible BlackBerry?
For example, a screen is in the foreground and we disply dialog box so that the screen is visible but not to focus, therefore, at this time that methos called when we close this dialog box?
Please, help me please please
Override the following methods in your class to screen according to your needs
1. when the screen button to the stack
Call
onDisplay() or
onUiEngineAttached(boolean attached) - so attached is true then your screen is at the top of the screen
2. When you are in a backlight and the lcd screen turns off to your state of rest and turns on again when you actively use this form
call
onVisibilityChange(boolean visible) - if visible is set to true, then you get the focus when the lcd display turns
3. when your application moves to the background by clicking the red end button (i.e. without quiting the app, yet yours is active in the background)
call
onExposed() - when your application comes to the foreground of the background or during any type of screen that is in the top get popped
& call
onObscured() - when your application moves to the background, or when a screen pushed above your current screen more

How can I change the amount of time before a call to voicemail
How can I change the amount of time before a call to voicemail?
-alex-
You will need to contact your carrier and see if they can change. There is no setting on the phone, only the owner can modify it, if they can. Not all carriers cannot change, and even if they can, it's a very short period. This has to do with the configuration of the call. At least you know that it's all the time and not the number of ringtones.
