Throws Throwable
Hi,
I have come across the classes where for handling the exceptions, they have used as
'throws Throwable'.
It gives me confusion since from my understanding we need to throw only the exception and not this Throwable class itself.
Could anyone help me understanding the idea behind this.
Thanks in adv.
-Bh.
Throwable is the superclass of Exception & Error.
have a look :
http://java.sun.com/docs/books/jls/secondedition/html/exceptions.doc.html#44278_
in general you can throw any subclass of Throwable or Throwable itself.
have a look for Throw statement:
http://java.sun.com/docs/books/jls/secondedition/html/statements.doc.html#79311_
Hope this will clear your doubt.
Thanx

Question about throws exception in interface and realized class
Hi,all
If I define a method In the interface like that-
public void Execute() throws NumberFormatException; In the realized class, I can define this method like that-
public void Execute() throws RuntimeException{
System.out.println("test");
}This is a right realization. But if I manage it to throws Exception or to throws Throwable in the class it leads a error. Why add this restrict only to Exception? What is the purpose of this way?
Greetings and thanks,
JasonWhen you say "throws NumberFormatException" you are really saying:
When using classes implementing this interface, you have to be prepared to deal with them throwing a NumberFormatException. Other exceptions won't happen.
When you come to implement it, it might not be possible for it to throw a NumberFormatException, so there's no reason why you should have to lie about that. Code handling it directly will be fine (it doesn't throw a NFE) and code handling it via the interface will be fine (it will handle NFEs, they just don't happen).
If your concrete implementation throws other sorts of exception, such as Exception or IOException, and so on, it's incompatible with code that's manipulating the interface. The interface says "NFEs might get thrown, nothing else will." while your implementation says "IOExceptions might get thrown".
So that explains why you can't use arbitrary exceptions. The special case is RuntimeException. RuntimeExceptions don't have to be caught, and it's expected that they can happen at any time - so there's no point trying to catch and handle them as a general case.
The classic example of a RuntimeException is a NullPointerException. You don't need to declare your method as throwing a NullPointerException even though it might get thrown. And you don't have to add NullPointerException to the throws part of the interface definition, because you already know that the concrete implementation could throw a NPE at any time.
Hope that helps (a little).
I'd recommend reading the API documentation on RuntimeException and Exception to get a clearer insight into this.

Does Throw in a JCD rollback whole JCD??
Hi All,
I have a Try Catch in a JCD.
When an error is raised i want to send a JMS to a queue(error log) then Throw so the Redelivery Handling kicks in.
The send a JMS to a queue doesn't ever happen though, unless i remove the Throw.
Seems like everything is rolled back by the throw?
Is there any way i can send this JMS to the queue and throw.
Cheers,
KenThis is cut down, but shows whats happening.
Basically placing a file in a directory.
Redelivery Handling setup in connectivity map in link between queue & this JCD to try a certain no. of times.
If a delivery fails i want to write to a queue (notificationSend in catch) as well as using Redelivery Handling.
The problem is...
1) Throw is needed to make the Redelivery Handling work, but then otdJMS_NOTIFICATIONSUMMARY.send( jmsMsg ) never sends massage.
2) if throw is disabled then message will send, but Redelivery Handling won't work, presumably because it thinks JCD didn't fail.
How can i use Redelivery Handling and send a message to a queue?
Am i approaching this the wrong way?
public void receive( com.stc.connectors.jms.Message input, com.stc.eways.batchext.BatchLocal BatchLocalFile_eWay_Out, , com.stc.connectors.jms.JMS otdJMS_NOTIFICATIONSUMMARY)
throws Throwable
try {
// Setup Batch eWay
BatchLocalFile_eWay_Out.getClient().setPayload( input.retrieveBytesFromMessage() );
BatchLocalFile_eWay_Out.getClient().put();
} catch ( Throwable t ) {
notificationSend( input);
// throw to use "Redelivery Handling"
throw t;
// Assign User Properties & send to Notifictaions project
private void notificationSend( com.stc.connectors.jms.Message input )
throws Exception
// Create new message
com.stc.connectors.jms.Message jmsMsg = otdJMS_NOTIFICATIONSUMMARY.createMessage();
jmsMsg.setTextMessage( input.getTextMessage() );
// send massage on it merry way...
otdJMS_NOTIFICATIONSUMMARY.send( jmsMsg );

Can i call a JMenuBar in a number of JFrame(s) ?
Hi ,
I've a program with a number of JFrames.
I wanted to add a JMenuBar for each frame of my program, this menu bar has the same design code and the same events code in all the program frames, so is there a way to create this JMenuBar once only & call it some how in every JFrame to load it directly instead of writing its same code a lot of times for every JFrame ?
Thanks ,

Sure i will.
But i have posted that code after trying all the possibilities.
I thought that getUI() failed exception may have the resulkt for not implementing any method or any registration problem with UIManager.
So, that is my test code not exactly i have posted that in hurry.

Problem with JNDI and JSP in Tomcat
Hi,
Basically, what I've done is to use the Tomcat administration web
application to create the DataSource, which looks like it populated the
server.xml (see below). I then try to access the testconn.jsp, and am
getting that "Name java:comp is not bound in this Context" error.
I was wondering if anyone could tell me what I'm doing wrong?
Thanks,

</Context>Hi,
First of all, you can find alot of information about this in the forum about jsp's.
I think a good thing to do is not to put your context tag directly into the server.xml file.
What you should do is create a context.xml file with the context-tag in it, and put it in the META-INF directory of your .war file. Upon deployment to tomcat5 this file will be extracted from the war, copied to the conf\enginename\hostname directory, and it will be renamed to contextName.xml.
I think you are developing directly into the webapps directory, and I believe you should avoid that and use the deployment feature of the manager web-app or you should use the deployertool from you ide or standalone ant.
anyway, for starters try to remove the context tag from the server.xml file as described above, and check out the jsp / jdbc forums for simular problems and answers.
good luck -
Event Dispatch Thread Hangs, what is wrong?
The Event Dispatch Thread Hangs when showing a modal dialog while running a
SwingWorker Thread.
I have included my code at the bottom of the page. There are three classes. I have posted a bug report to red hat. But I want to make sure my code is correct.
My test case just puts the SwingWorker to sleep
but the problem occurs if I do something real, like connect to a database, etc.
Also I have tried little different variations of the logic calling
setVisible(true)/(false) in different places and the same problem occurs.
It seems to work with Sun JDK, note I am using IcedTea with Fedora Core 8.
Version-Release number of selected component (if applicable):
[szakrews@tuxtel ~]$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea Client VM (build 1.7.0-b21, mixed mode)How reproducible:
Every couple times.
javac TestClass2
java TestClass2eventually it will hang. If it doesn't try again.
You don't have to wait for the program to finish either.
The program runs the Dialog 10 times but it never works or fails in the middle, it will either work or fail from the first dialog displayed.
I have included a thread dump. That is about the most informative information I can get. Neither tracing nor writing a custom ThreadQueue or Drawing Manager to trace events produces any helpful information.
Actual results:
The JProccessBar won't move, and the SwingWorker finishes but the done() method is never run. The PROGRAM is not hung however because if I close the dialog then it will continue.
Expected results:
The JProccessBar should always move and the SwingWorker should always run the done() method.

}There's nothing directly wrong with it, but it will
prevent other threads acquiring the class lock - but
that may be what you want.True. Although the typical case for code that looks like this would be to use wait--usually the various threads in question require the same lock, so you have to use wait in order for the waiting thread to give it up and allow the other thread to do its work. Hard to say for sure though what he's doing.
Also, if loading is all that the other thread does, and you're waiting for that thread to die, use join. But then, if that's the case, and you're only waiting for a single other thread, then you might as well just put it all in one thread, as already indicated. -
Right way to dispose frame/components/containers?
Hi,
My application creates a lot of frames with lots of containers and components (heavyweights as well as light weights) inside them. I have obeserved that none of the frames/containers/components get finalized unless I do a remove/removeAll() over the respective container. Currently I just make a call to frame.dispose() to dispose it off and assume that all components would be reclaimed by the garbage collector at some point of time. Is that the right way to dispose off the frames and mark all its child components for garbage collection? Or is an explicit call to removeAll() required to release the memory. I am aware that garbage collection doesn't happen immediately and may take a while before the GC collects objects. I have run the application continuously for couple of hours and created/disposed a lot of frames during that period. GC recollected none of them (none of the components either) except for those that were removed by an explicit call to remove or removeAll during the lifetime of the session. I even hit OOM errors but none of the components were recollected.
What could be the problem?
Some additional information:
I overridden removeNotify() and finalize() methods to see what's going on. For all components removeNotify() was called (even if I don't do explicit remove/removeAll and just dispose off the frame) but finalize never gets called. My methods:
public void removeNotify()
super.removeNotify();
System.out.println("Remove notify called "+compId);
protected void finalize() throws Throwable
super.finalize();
System.out.println("Finalized component "+compId);
}Thanks in advance.
Edited by: crack_it on Jul 31, 2009 8:52 AMSorry to bother guys. The problem was not with AWT but with one evil component that was displayed inside most of my Frame classes and was also registered as an Observer with an Observable class. The event at which the component was supposed to unregister itself with Observable never got fired and this one reference prevented garbage collection of entire gui brigade. Damn! Tiny monster.
Anyway the issue stands resolved. Thanks for your time. -
Custom Login using the Pluggable Identity Management Framework
Hi all,
We are trying to establish 2 ways into our application:
1. via a login form
2. seamless login from an external application
To achieve this we are trying to build our own custom authentication using the pluggable IDM framework.
Basically if a secure page is requested, we want to check the header/cookie/request (don't mind which) for a key which is provided by the external application. If present, the key is validated against a web service provided by the external app, the identity is asserted and the user is entered seamlessly into the application. If the header/cookie/request does not contain a key the user is to be redirected to a login page, where they can input username and password which will be validated against our database.
We've created a Token Collector and Token Asserter class, we've modified our custom Login Module to retrieve the identity created by the Token Asserter but we haven't worked out how to get the alternate login page working for users which don't come through the external application.
Has anybody built anything similar? From the documentation it appears we should be able to achieve our goal using the pluggable IDM, but we're going around in circles a bit at the moment.
Any help/sample code would be greatly appreciated.
thanks.Can you tell why the page is not working? I mean, any errors ? What happens when you try to open the protected resource?
Here is an example of the code, I removed some part of the code specific to the bussines so if you have doubts just let me know

How can I generate the keystore file and know the private key alias so that i can generate the sign using sign().
thanks in advance.
RanjanIt is possible to import a .p12 file into a keystore with a small Java program...
I found a sample to do this about a year ago, the source page is no longer valid. I have made some slight modifications to the original program, but left credit to the original author in the top (to the best of my knowledge).
Sample execution being:
$ java KeyStoreMove PKCS12 ~/igo.p12 p12-pas JKS ~/.keystore key-pas
Source alias: lester igo id #2
Rename alias to [<return> to keep original alias]: my-cert
New alias: my-cert
importing key lester igo id #2
keystore copy successful

Hi all,
I have a problem with printing JTable.
My application has a submit button,JTable and Print Button.
As I click on the Submit button, the data is retrieved from the Database(MS Access) and displayed on the JTable.
Now when I click on the Print button, the printer properties dialog box is displayed. But when I click on the print button in the dialog box, nothing is printed on the paper.
I checked the printers and faxes in the control panel, It showed Java printing under the Document name and Printing under the Status. It is displayed for sometime and then disappeared after some time. But nothing is printed on the paper(not even the blank paper).
I tried a lot but couldn't understand the problem.

Sample JAVA Mobile Server Publish code, and technical questions
Dear Oracle technical representative, or user:
I need to programmatically create, and remove publications using the pure JAVA classes of Consolidator, ConsolidatorManager, and ResourceManager for the Mobile Server in OracleLite 9i Release 5.0.1. On the creation side I have managed to get the example found in the directory OraLite501\Mobile\Server\Sample\Sample11 functioning using my installation parameters. I had a very difficult time of it because (1) the sample11 code fails to open an jdbc connection to the Mobile Server Repository Schema with the function Consolidator.OpenConnection, and (2) the ResourceManager function openConnection will not work unless the Webtogo.ora file is in the current working directory. The ConsolidatorManager function OpenConnection may also not work unless the Webtogo.ora file is in the current working directory, but I did test the hypothesis. Both of these problems need to be addressed in the sample11 code, and documentation to save other software developers from wasting hours of their valuable time. See line 223, 386, and 448 in the Publish.Java code that follows this problem description.
With the above two problems resolved, I can now programmatically create publications, but no hints on how to programmatically remove a publication exist in the documentation. The application I am developing will require the dynamic creation, and removal of publications. Also, when developing applications the complete removal of a publication is absolutely necessary when you have botched a publication. Thus my first question is What sequence of ResourceManager, and ConsolidatorManager function calls will completely remove a Publication?.
I also have two issues remaining with the code that I have so far developed. These issues will most likely be resolved, when I obtain instructions on how to completely remove a publication, and associated users. But, perhaps not. Referencing the Publish.java file that follows this problem description,
1. The ResourceManager function dropUser does not drop a user. See my comments, and code beginning at line 277 in Publish.java. Do I need to de-instantiate all subscriptions, and unsubscribe all subscription users before calling this function.? I think, I tried the de-instantiate, unsubscribe sequence without success, but in the confusion I may not have made the try.
2. How do I get rid of an index created with the ConsolidatorManager function DropPublicationItemIndex?. My comments on this problem begin at line 522 in Publish.java. For some reason the DropPublicationItemIndex function call made below line 448 does not work. What function calls are required prior to calling the DropPublicationItemIndex function?
Throughout the Publish.java code, I have made comments about some of the problems that I have had in getting the sample11 code working for my installation parameters. I think these comments should help the programmers maintaining the ResourceManager, and ConsolidatorManager code improve the stability of the programs. Please pass these comments, and attached files to the appropriate individuals,
if you are in a position to do so.
The other files that follow the Publish.java code are
1. Compile.bat - Compiles Publish.java using j2sdk1.4.0.
2. Run.bat - Executes Publish using \ j2sdk1.4.0\jre\server\jvm.dll.
3. Webtogo.ora
4. tnsnames.ora for the Mobile Server.
5. tnsnames.ora for the Database.
Feel free to access my server if you need to do so in resolving my problems. The parameters you will need to gain access can be found at the top of Publish.java, and in the included *.ora files.
Thanks,
Thomas G. Matney

End Database tnsnames.ora fileDear Oracle technical representative, or user:
I need to programmatically create, and remove publications using the pure JAVA classes of Consolidator, ConsolidatorManager, and ResourceManager for the Mobile Server in OracleLite 9i Release 5.0.1. On the creation side I have managed to get the example found in the directory OraLite501\Mobile\Server\Sample\Sample11 functioning using my installation parameters. I had a very difficult time of it because (1) the sample11 code fails to open an jdbc connection to the Mobile Server Repository Schema with the function Consolidator.OpenConnection, and (2) the ResourceManager function openConnection will not work unless the Webtogo.ora file is in the current working directory. The ConsolidatorManager function OpenConnection may also not work unless the Webtogo.ora file is in the current working directory, but I did test the hypothesis. Both of these problems need to be addressed in the sample11 code, and documentation to save other software developers from wasting hours of their valuable time. See line 223, 386, and 448 in the Publish.Java code that follows this problem description.
With the above two problems resolved, I can now programmatically create publications, but no hints on how to programmatically remove a publication exist in the documentation. The application I am developing will require the dynamic creation, and removal of publications. Also, when developing applications the complete removal of a publication is absolutely necessary when you have botched a publication. Thus my first question is What sequence of ResourceManager, and ConsolidatorManager function calls will completely remove a Publication?.
I also have two issues remaining with the code that I have so far developed. These issues will most likely be resolved, when I obtain instructions on how to completely remove a publication, and associated users. But, perhaps not. Referencing the Publish.java file that follows this problem description,
1. The ResourceManager function dropUser does not drop a user. See my comments, and code beginning at line 277 in Publish.java. Do I need to de-instantiate all subscriptions, and unsubscribe all subscription users before calling this function.? I think, I tried the de-instantiate, unsubscribe sequence without success, but in the confusion I may not have made the try.
2. How do I get rid of an index created with the ConsolidatorManager function DropPublicationItemIndex?. My comments on this problem begin at line 522 in Publish.java. For some reason the DropPublicationItemIndex function call made below line 448 does not work. What function calls are required prior to calling the DropPublicationItemIndex function?
Throughout the Publish.java code, I have made comments about some of the problems that I have had in getting the sample11 code working for my installation parameters. I think these comments should help the programmers maintaining the ResourceManager, and ConsolidatorManager code improve the stability of the programs. Please pass these comments, and attached files to the appropriate individuals,
if you are in a position to do so.
The other files that follow the Publish.java code are
1. Compile.bat - Compiles Publish.java using j2sdk1.4.0.
2. Run.bat - Executes Publish using \ j2sdk1.4.0\jre\server\jvm.dll.
3. Webtogo.ora
4. tnsnames.ora for the Mobile Server.
5. tnsnames.ora for the Database.
Feel free to access my server if you need to do so in resolving my problems. The parameters you will need to gain access can be found at the top of Publish.java, and in the included *.ora files.
Thanks,
Thomas G. Matney

Hello all,
I'm experiencing what I call a very subtle bug. Subtle because there are no exceptions, no memory leak, not even an error message.
My application uses BDB XML and it inserts, updates, removes and searches documents - pretty basic functionality. But after some time of use, my users are calling me saying the searches never return any results. I mean, they send a request, then it's sent to BDB, but it doesnt return.
First I thought it was another memory leak, but memory cosumption is high as always, but it is stable at some point. Just for checking, I restarted the server and tried searching again - dog slow, no return, even with 600MB free RAM.
The only solution was to run recovery, which I chose to do manually at this time (and I dont do it automatically yet). Started the server, and then it returns to its normal state.
So, I can just wonder what can possibility cause this? The containers are getting corrupted (although no corruption messages appear)? My Environment is managed by this class:

How to handle multiple database tables in a single UIX page?
Hi,
I am new to UIX & BC4J. I have to handle data from four different tables in the database. The scenario is as follows:
The tables are
1. user
fields are: userid number, name varchar2
2. business
fields are: businessId number, name varchar2
3. service
fields are: serviceId number, serviceName varchar2
4. userBusiness
userid,businessid (both are foreign keys) & form complex primary keys.
and userid,businessid, serviceId are primary keys.
Now my problem is: to create a webpage where
1. The userid is available in the httpSession Variable as string.
2. according to the userId stored in the session variable I have to retrieve the business names and show them in a choice i.e., pull down box.
3. I have to show the services provided by the business for the business name selected in the combo box.
Could anyone Please help me solve this problem? Could you please give me hints? I have truncated the other fields in the tables.
Thanking you,
Velpandian .SAt the moment, you can't do it declaratively. You have to do it in an event handler. Assuming you have the userid setup as a query parameter in the view object, something like this should get you started:
public EventResult handleEvent(
BajaContext context, Page page, PageEvent event) throws Throwable
HttpSession session = context.getServletRequest().getSession(true);
ViewObject view = ServletBindingUtils.getViewObject(context);
String userid = session.getAttribute("userid");
view.setWhereClauseParam(0, userid);
view.executeQuery(); -
Can I use multiple coherence instances on one JVM?
Or can I explicitly designate a tangosol-coherence-override.xml to coherence? If I can, how to?
Thanks.
Edited by: user8028833 on May 31, 2010 1:35 AMOK apologies as I was going to just post the bits of code but I didn't get much time last night.
This code was originally written by a couple of us who wrote some security and single sign on code for Coherence. The project is on Google Code here: http://code.google.com/p/coherence-security/
The source is a Maven project so it follows the Maven directory structure. If you look in the coherence-security-core test sources there is a package called com.oracle.coherence.patterns.security.test.starter which contains all the ClassLoader code and classes to start a Coherence "cluster" in a single JVM.
The com.oracle.coherence.patterns.security.ApacheDirectoryTest test class uses this code to start a cluster to run its unit tests. To start the cluster you call CoherenceClusterStarter.getInstance() for example the com.oracle.coherence.patterns.security.ApacheDirectoryTest testSecureClientWithUnauthorisedCredentials() method.
@Test
public void testSecureClientWithUnauthorisedCredentials() throws Throwable {
// Set the main class that runs to be the Secure servers
System.setProperty("coherence.incubator.mainclass", SecureSandboxStarter.class.getName());
// Make sure the cluster members run with the [email protected] Principal
System.setProperty("sun.security.krb5.principal", "[email protected]");
CoherenceClusterStarter.getInstance();
// Run the client as the Thomas the Tank identity ([email protected]) which is
// not authorised to connect as an Extend client in the extend-permissions.xml file
System.setProperty("sun.security.krb5.principal", "[email protected]");
LoginContext lc = new LoginContext("Coherence");
lc.login();
Subject subject = lc.getSubject();
try {
Subject.doAs(subject, new PrivilegedExceptionAction<Object>(){
public Object run() throws Exception {
SystemPropertyLoader.loadEnvironment("client");
System.setProperty("tangosol.coherence.security", "true");
CacheFactory.getCache("test");
return null;
fail("Expected to have a PortableException wrapping a java.lang.SecurityException thrown");
} catch (PortableException e) {
assertEquals("Portable(java.lang.SecurityException)", e.getName());
}In the code above the first line sets the coherence.incubator.mainclass System property to the name of the class that will be run (in this case our secured DefaultCacheServer wrapper). Then the next line starts the psuedo-Cluster which the rest of the code uses.
Note
The Google Code above was originally done due to a requierment to secure Coherence using Active Directory (Kerberos). The code was started on 3.4 and eventually on 3.5.3 and then used to help Oracle change the Security API for 3.6. There are a few things not quite right and a few "gotchas" that are not in the code online.
Anyone is welcome to take it and use it but I and the others who worked on it offer no warranty or guarantee it will work for you.
As of Coherence 3.6 there are much simpler ways to do security - although if you want to use Active Directory or Kerberos some of the code on Google will still be useful.
Any problems or questions give me a shout either here or mail [email protected].

JK
