Trying to implement 2 interfaces
I am wondering how i might implement two different interfaces into a class (ItemListener and ActionListener) so that i can have checkboxes and buttons that will create events. The class already extends Applet so that i can't just extend an adapter and then implement one interface, i need to be able to inherit from Applet and each interface. Will i have to just create another class that implements one of them and create objects of that class?
Hi,
there's not problem to implement more than one interface:
public class MyClass extends Applet implements ItemListener, ActionListenerRegards

No implementation interfaces created using jaxb 2.0 ?
Hi,
I've downloaded the jaxb 2.0 RI and am trying to follow the short tutorial at http://java.sun.com/developer/technicalArticles/WebServices/jaxb/index.html.
On trying to bind the schema via xsj,sh, which also is meant to generate the implementation interfaces (in an impl directory), I see these aren't created - the other classes are generated OK. Where or how should they be created ?
thanksI am on the same boat. Have you found the answer to this?
Thanks,

We are trying to implement a process so that any document that needs to be printed through our Java application will be printed as PDF using Adobe Reader.
For which, We created and execute the below command line to call Adobe Reader and print the PDF on a printer.
"C:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe" /T "\\<Application Server>\Report\<TEST.PDF>" "<Printer Name>".
Current Situation: The above command line parameter when executed is working as expected in a User's Workspace.
When executed in a command line on the Application Server, it is working as expected.
But, the same is not working while executing it from Deployed environment.
Software being used: 1. Adobe 11.0 enterprise version. 2. Webshpere Application Server 8.5.5.2.
Please let us know if there is a way to enable trace logs in Adobe Reader to further diagnose this issue.This is the Acrobat.com forum. Your question will have a much better chance being addressed in the Acrobat SDK forum.

PL/SQL procedure successfully completed.ORA-20001 isn't an Oracle error message it was coded into your application by a developer: Look it up.
Consider too the following:

Trying to implement a mail queue
I'm trying to implement a very basic mail queue using ExecutorService and a Callable split into a producer which builds the email and an email queue and a consumer to send the queued message out but I keep getting:
java.lang.NullPointerException
at javax.mail.Transport.send(Transport.java:97)
at org.bedework.mail.sendMail.call(sendMail.java:45)
at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source)

at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
I'm not sure how to get the transport variable passed across and read by the consumer thread.
The consumer code is:
public class sendMail implements Callable<Object> {
private ArrayBlockingQueue<Object> queuedMail;
private Transport trans;
private MimeMessage msg;
private Logger log = Logger.getLogger(sendMail.class);
public sendMail (ArrayBlockingQueue<Object> queuedMail, Transport trans) {
this.trans = trans;
this.queuedMail = queuedMail;
public Object call() throws Exception {
try {
queuedMail.poll();
synchronized (queuedMail) {
if (queuedMail.isEmpty()) {
queuedMail.wait(1000);
try {
trans.send(msg);
Thread.sleep(1000);
} catch (Exception e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
return null;
}The code that calls it is:
tr = sess.getTransport(config.getProtocol());
pool.submit(new buildMail(sess, cal, originator, to, subject));
pool.submit(new sendMail (mailqueue, tr));I'd be grateful for any pointers in getting this sorted out.First, read this FAQ item:
[http://java.sun.com/products/javamail/FAQ.html#send|http://java.sun.com/products/javamail/FAQ.html#send]
Then explain to me how "msg" is ever set in your sendMail class. -
Trying to implement EAP/TLS using java (as part of RADIUS server)
Hi
This is a cross port since I didn't know which forum to post in!
I'm trying to implement a RADIUS server (EAP/TLS) as part of my master thesis. I'm not used to Java SSL libraries and can't get it to work. The server will respond to an accesspoint that uses 802.1x. I have created certificates using openssl and imported the "cert-clt.pl2"and "root.pem" to a laptop trying to connect to the accesspoint. On the server side i imported the "cacert.pem" and "cert-srv.der" using keytool to a keystore. In my code I read the keystore and create the SSLEngine with following code:
KeyStore ksKeys = KeyStore.getInstance("JKS");
ksKeys.load(new FileInputStream("certs/FeebeeCommunity.keystore"), passphrase);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ksKeys, passphrase);
KeyStore ksTrust = KeyStore.getInstance("JKS");
ksTrust.load(new FileInputStream("FeebeeCommunity.keystore"), passphrase);
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(ksKeys);
sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
sslEngine = sslContext.createSSLEngine();
sslEngine.setUseClientMode(false);
sslEngine.setNeedClientAuth(true);
sslEngine.setWantClientAuth(true);
sslEngine.setEnableSessionCreation(true);
appBuffer = ByteBuffer.allocate(sslEngine.getSession().getApplicationBufferSize());
appBuffer.clear();
netBuffer = ByteBuffer.allocate(sslEngine.getSession().getPacketBufferSize());
netBuffer.clear();All I want to do with TLS is a handshake.
I'm not talking ssl using sockets instead I receive and send all TLS data encapsulated in EAP packet that are incapsulated in RADIUS packets. I start off with sending TLS-Start upon I recive TLS data. I handle it with the following code:
SSLEngineResult result = null;
SSLEngineResult.HandshakeStatus hsStatus = null;
if( internalState != EAPTLSState.Handshaking ) {
if( internalState == EAPTLSState.None ) {
TLSPacket tlsPacket = new TLSPacket( packet.getData() );
peerIdentity = tlsPacket.getData();
internalState = EAPTLSState.Starting;
try {
sslEngine.beginHandshake();
} catch (SSLException e) {
e.printStackTrace();
return;
else if(internalState == EAPTLSState.Starting ) {
internalState = EAPTLSState.Handshaking;
try {
sslEngine.beginHandshake();
} catch (SSLException e) {
e.printStackTrace();
TLSPacket tlsPacket = new TLSPacket( packet.getData() );
netBuffer.put( tlsPacket.getData() );
netBuffer.flip();
while(true) {
hsStatus = sslEngine.getHandshakeStatus();
if(hsStatus == SSLEngineResult.HandshakeStatus.NEED_TASK) {
Runnable task;
while((task=sslEngine.getDelegatedTask()) != null) {
new Thread(task).start();
else if(hsStatus == SSLEngineResult.HandshakeStatus.NEED_UNWRAP) {
try {
result = sslEngine.unwrap( netBuffer, appBuffer );
} catch (SSLException e) {
e.printStackTrace();
else {
return;
}When I try to send data I use the following code:
SSLEngineResult.HandshakeStatus hsStatus = null;
SSLEngineResult result = null;
// netBuffer = ByteBuffer.allocate(EAPTLSMethod.BUFFER_SIZE);
netBuffer.clear();
while(true) {
hsStatus = sslEngine.getHandshakeStatus();
if(hsStatus == SSLEngineResult.HandshakeStatus.NEED_TASK) {
Runnable task;
while((task=sslEngine.getDelegatedTask()) != null) {
new Thread(task).start();
else if(hsStatus == SSLEngineResult.HandshakeStatus.NEED_WRAP) {
try {
result = sslEngine.wrap( dummyBuffer, netBuffer );
} catch (SSLException e) {
e.printStackTrace();
else {
if( result != null && result.getStatus() == SSLEngineResult.Status.OK ) {
int size = Math.min(result.bytesProduced(),this.MTU);
byte [] tlsData = new byte[size];
netBuffer.flip();
netBuffer.get(tlsData,0,size);
TLSPacket tlsPacket = new TLSPacket((byte)0,tlsData);
if( size < result.bytesProduced() ) {
tlsPacket.setFlag(TLSFlag.MoreFragments);
return new EAPTLSRequestPacket( ID,
(short)(tlsPacket.getData().length + 6),
stateMachine.getCurrentMethod(), tlsPacket );
else {
return null;
}After I sent TLS-Start I receive data and manage to process it but when then trying to produce TLS data I get the following error:

I tried to implement photo albums using iweb and got a publishing error.
I tried to implement photo albums using iweb and got a publishing error. All was fine with my site until I added the photo album page. The software doesnt say what the error is exactly, only that it is a publishing error to my ftp
Exact message "There was an error communicating with the FTP server. Try again later, or check with your service provider."
If I reduce the albums inside to 1 then it seems to work but that takes away from the usefullness of multiple albums.
my iWeb version is 3.0.4 (601)Publish your site to a folder on your hard drive to see if the publication will proceed successfully and open the site locally with your browser to confirm all of the alums are there and work. If they do try the following:
delete the iWeb preference files, com.apple.iWeb.plist and com.apple.iWeb.plist.lockfile, that resides in your Home() /Library/Preferences folder.
go to your Home()/Library/Caches/com.apple.iWeb folder and delete its contents.
Click to view full size
launch iWeb and try again.
If you're still not able to publish from iWeb to your server download and use the free Cyberduck to upload your website files to the server. Users have found that CD has been successful when iWeb had problems.

Public class implements interface
I am taking my first crack at interfaces: I have superclass A which is a parent of class B, which implements interface C. I need to use class B to make 3 variable instances within class A. I think I will use interface C to make calculations based on the 3 variables. Where do you recommend that I declare and set values for the 3 variables if I need to output the values at the top, in superclass A?
I'm just a little unclear on pulling these objcts together... thanks in advance.I am taking my first crack at interfaces: I have

I'm just a little unclear on pulling these objcts
together... thanks in advance. If your variables are going to be used by your superclass A then they had better be declared there. You can work with them whereever you want.
I'm not sure what you are saying about "...use interface C to make calculations based on the 3 variables." You can't do calculations inside an interface. Furthermore, if B extends A and implements C then A and C are going to be completely separate entities. Any reference to C, even if it is actually an object of type B, will not be able to use anything in A--unless you cast it to B, in which case there is no use in making an interface at all.
I probably just confused you, but oh well...

I have to add a main view to the portfolio items and integrate the view WI_DMS of the web dynpro component DMS_DPR to the same. When I try to do it, it says 'WI_DMS does not implement a valid interface". Is there any way to implement the valid interface dynamically? PLease help.
>i have been using ( implementing ) interfaces in the components, for example i used iwd_value_help. however i still have no clarity how WD framework is able to communicate with the component implementing interface iwd_value_help.
Web Dynpro can create a component usage based upon the interface type alone. This is very similar to normal ABAP OO when you create/get an instance of a class but only know the interface. Basically this is polymorphism at the component level.
>the basic question here is, what is wd framework, is it class implementing interfaces generated when we create views and other stuff. and this class( WD fw ) is going to call these implemented methods of the interface??
Simple answer: yes, exactly as you describe. Everything relates back to generated and local classes. The framework can interact with them becuase all the generated classes implement SAP provide framework interfaces. -
Trying to implement MAA on 4node race
Subject: Trying to implement MAA on 4node race
RDBMS Version: 10.2.0.3

Error Number (if applicable): ORA-12154
Product (i.e. SQL*Loader, Import, etc.): DATAGUARD
Product Version: 10.2.0.3
Trying to implement MAA on 4node race
Can anyone clarify my questions related to RAC & DATAGUARD.
We are trying to implement 4node physical standby, our primary is a 4node RAC.
How does oracle ship the archive logs and apply at the secondary(physical standby). Does we need to mount all the instances on the physical standby or only one instance?
what we have done is mounted one instance recovered the primary database at physical standby.
We are currently shipping the logs manually and recovering at the physical. we are hoping that the automatic shipping of archive logs and recovery at the physical, will catch up when its current. Is my assumption correct???
On the primary we see the following eroors:

Can anyone let me know how MAA functions. I mean..4 node RAC shipping logs and applying at 4 node physical standby.........

raghu559Hi josefli
i got quite different response from oracle metalink forum. can you explain me about this and how we can achive failover?
here is what it said:
In a RAC configuration, you need to make sure you load balance
the archive receiving on standby site. If you just use
one instance to receive all the archive logs and apply them,
it could potentially create bottleneck on a very busy
environment. So you have to use all the RAC instances
even on the DR site and they all need to be mounted.
You need to designate one instance as the applier, which would
run the MRP, and all the instances as receiver.
Primary 1 ===> Standby 1 (receiver and applier)
Primary 2 ===> Standby 2 (receiver only)
Primary 3 ===> Standby 3 (receiver only)
Primary 4 ===> Standby 4 (receiver only)
Let us assume your database name is "finp"
Primary Site

*.log_archive_dest_state_2=enable
Add tns entries for finp1_stby, finp2_stby, finp3_stby and finp4_stby on
primary site tnsnames.ora. All these entries would be pointing
to DR site.

finp4.fal_server=finp4_stby, finp1_stby, finp2_stby, finp3_stby
*.log_archive_dest_state_2=defer
Add tns entries for finp1_stby, finp2_stby, finp3_stby and finp4_stby on
standby site tnsnames.ora. All these entries would be pointing
to primary site.
What is good about this type of setup is that if one of the
server is unavailable, still the configuration would work
withoout any chagnes. During switch over and switch back,
you don't need to any changes on spfile or tnsnames.ora file.
Note the fal_server is listing all the server names so that
it could get the archive files from other servers if
one of the server would be unavailable.
So i need to place all the instances on physical standby in mount stage? like i said currently we are recovering on one instance. Do we need to make any changes to other 3 instances(physical standby)? or just do a startup mount on those 3nodes? -
Perspective for Java technologies : implementing interface on late.
In Java, to implements the adapter pattern's; we have to create a new class that have a link with the adaptee class and implements the adapter interface.
class MyAdapter implements IAdapter
public MyAdapter( Adaptee a );
}or, if we need protected methods :
class MyAdapter extends implements IAdapter
public MyAdapter( Adaptee a );
}then, to call the method void foo( IAdapter i ); ;
we have to do xxx.foo( new MyAdapter( adaptee ) );it could be simpler if java allowed to implement interfaces after defining the java class.
public class Adaptee
}and then, in another file, something like,
implementation of IAdapter for class Adaptee
}would be equivalent to
public class Adaptee implements IAdapter
}The advantage of the first method is that you can adapt very easy external classes from external jar file.
thank's for coments.An interface is a contract which tells the compiler
that a class that implements it implements a set of
method signature which perform certain actions.That's right, but my idea is not to change the interface, but to change the external class, making it implements the existing interface.
If you overlay an interface on someone else's class,
the signature match (if there is one) could happen by
coincidence. There's no guarantee that a method with
a signature that matches one in your interface
actually has the same function.I didn't say that an external class should be viewed as an interface without a specific implementation of this interface for the external class. But, instead of making a new class extending the first and implementing the interface, just define a specific implementation of the interface for this class, as if it was make at class declaration. -
Hi I am trying to implement AJAx functionality in my JSP page.. It will work to bring or open the callup window when ever any one puts mouse over any image.
Well i am sending an product ID to my servlet and getting response in form of XML text but i am not able to track the response from servlet the command i am using for it is...
var ro;
function createRequestObject(objurl,objurl1)
var url1 = "<%= link("catalog", "catProductDescription", extraParam) %>" ;
document.dataForm.OP.value = "description";
var url = url1 + "&ProdId=" + objurl ;
if(window.XMLHttpRequest)
ro = new XMLHttpRequest();
else if(window.ActiveXObject)
ro = newActiveXObject("Microsoft.XMLHTTP");
ro.open("GET", url, true);
ro.onreadystatechange = handleResponse;
ro.send(null);
function handleResponse()
if(ro.status == 200)
var message = ro.responseXML.getElementsByTagNam("message") [0];
setMessage(message.childNodes[0].nodeValue);
function setMessage(message)
alert(message);
I am trying to send product description from Servlet by using:
response.setContentType("text/xml");
response.setHeader("Cache-Control", "no-cache" );
response.getWriter().write(msProdBean.getDescription());
please try to guide me with proper code.try this handle response function
function handleResponse()
if(ro.readyState == 4)
var response = ro.responseText;
var update = new Array();
if(response.indexOf('||' != -1))
update = response.split('||');
// access the response string from servlet with this variable, update[0];
// eg: alert(update[0]) ;

Hi guys. I have a test on array and inheritance and polymorphism. I didn't quite understand what is the benefit of implementing interfaces.
Something like this:
public class static Child extends Parent implement A,B,C
Where A,B,C are interfaces.
I need to get this straigth before the final test tomorrow. Thanks a lot.By implementing an interface, a class declares what it does. This means that the compiler and other classes can determine whether that class is suitable for some operations.
So given your example Child which implements interfaces A, B, and C, there could be another class with method:
public boolean doSomething(A aclass) {
}This method can be given an instance of your "Child" class, or a different class which also implements the A interface.
Interfaces say what a class does, as opposed to how it does it.
