LookupXRef not throwing any exception

Hi All,
We are using ESB Cross referencing out of box functionality provided with 10.1.3.3 SOA Suite.We have a case where we need to have some busineess logic when the value we are trying to look up in the Cross Ref table doesnot exists , in that case we tried to use needAnException(set to true()) field in the lookupXRef function inside the transformation.However its not throwing any exception in the BPEL Process.Instead it is avoiding other fields in getting populated underneath it in that complex type.As a result we are losing important business data inside the BPEL Process.Same is the case for PopulateXRefRow function as well while we are trying to insert a duplicate value into the Cross referencing table from BPEL Process.
We need an exception for the above two cases.Are there any work arounds for these.
We are in an urgent need of it.Can any one help us?
Regards,
Venkat.

Why constructor of rmi server throws remote exception

why is it that the constructor of the class extending UnicastRemoteObject i.e rmi server has to throw RemoteException?

Writing an RMI server is a matter of defining a class, exporting it when constructed and implementing one or more remote interfaces. How to export?
auto export happens when u call super() in the constructor. It is then registered with the rmi system and made to listen to a TCP port. The various constructors for UnicatRemoteObject allow the derived classes to export at the default port.
Because this automatic export step occurs at construction the constructors throw this exception.

Why a method can not be invoked in JSP ???

I define a method in a JAVA Class file,as this:
public Enumeration getElementsNamed(String name, String parentname) {
Element elem = doc.getDocumentElement();
NodeList nodes = elem.getElementsByTagName(name);
int size = nodes.getLength();
Vector elemVec = new Vector(size);
for (int i = 0; i < size; i++) {
Node node = nodes.item(i);
     if (nodes     .item(i).getParentNode().getLocalName().equals(parentname)) {
          elemVec.addElement(new UddiObject((Element) node));
          return elemVec.elements();
I want to get a Element who's Localname is the name and his parent Element's laocalname is the parentname from a DOM tree.
This can be run well in a normal Java environment just as JDK1.4.
and is a JSP file,I import the Class first.
and invkoed the method in somewhere, the TOMCAT give me an error:
The server encountered an internal error () that prevented it from fulfilling this request.

Persist does not throw any exception in a JUnit test

I am implementing a JUnit test using Toplink as JPA provider. I must be missing something because I try to persist two times the same entity and no exception is thrown. Neither PersistenceException nor any other type of exception. The code cannot be easier:
@Test
public void testAddExistingTeam() throws Exception {
Team team = new Team("team2");
try{
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("fofo");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
em.persist(team);
em.persist(team);
em.getTransaction().commit();
em.close();
catch(Exception e){
e.printStackTrace();
Notice the two em.persist(team).
This code does not seem to either enter the catch block or produce any sort of exception. On the other hand, I have checked that after the first
em.persist(team); the team is really managed.
The relevant parts of the Team class definition follow:
@Entity
@Table (name ="TEAM")
public class Team implements Serializable {
@Id
@Column (name="NAME")
private String name;
@ManyToOne
@JoinColumn (name="CLUB_NAME", referencedColumnName="NAME")
private Club club;
private Category category;
private String email;
@ManyToMany(mappedBy="teams")
private List<Competition> competitions;
public Team (String name){
this.name = name;
this.club = null;
this.competitions = new ArrayList<Competition>();
....getters/setters....and more constructors.
I am really puzzled by this issue. Somebody could help??? I would be really grateful!!!
Josepma

This is expected behavior as persist is a no-op if called on a managed entity (other than to cascade over relationships marked with cascade.Persist), and the first persist call makes the passed in team entity managed.
Try calling em.flush(); and em.clear(); between the persist calls to get an exception.
The first flush will ensure the team is inserted in the database, while clear will detach it so that the second persist call will try to insert the team. JPA providers are not required to throw the entityExistsException on persist - it can be delayed until the transaction is flushed or committed, so you are likely to get a PersistenceException from the commit instead of EntityExistsException from persist.

Chris

Dbms_job.submit - job is restarting but - not throwing any exceptions

We have a job that is a simple loop that looks for (wakes up by) looking for messages coming in using DBMS_PIPE.
The job has been restarting arbitrarily but - we're not seeing messages generated via any of the associated exception handlers.
No idea why it's restarting when it fails.... currently - I'm just looking for a way to have the dbms_job.submit call NOT automatically restart if it has issues.
Currently just calling as such:
DBMS_JOB.submit(jobno, 'pkg_package.listen;');
Running on 10.2.0.4.0
Any insight is appreciated.
Is there a way to prevent it from automatically restarting and - is there something I should be looking for specifically around dbms_job when it comes to the exception handling in the packages/procedures it's running??
Thanks.

We generate a log record in a table using an autonomous procedure when an exception is raised.
Where I'm seeing the log records stating an issue with the job - I'm also seeing the tracefile / alerts being generated.
When the job starts - we log a record stating it's started....
In many instances - I'm seeing it log a start but - there's no corresponding trace file (i.e. - it wasn't manually started - it was processing and - then - without exception 'died' - didn't generate an error but - just started up again).
I've no idea what's going on here. I've validated that everywhere through the underlying package the job is running that the exceptions are being logged. Yet - it's arbitrarily starting up again on some occassions (and - I can't seem to find any general commonality around when this is happening or - what would be causing it).
So - I'm thinking this is an issue with the DBMS_JOB or - something else funky going on....
As an FYI - This job is simply a loop that waits to receive a message on DBMS_PIPE that then fires off a package procedure when it receives the message.
In the interim - to alleviate data issues as a result of it processing the same data twice - I'm trying to prevent it from auto restarting... is there a way to do this?

Why my method can not receive the string from JNI

JNIEXPORT jstring JNICALL Java_playaudio_BeatTrack_myBeatTrack

const char* filename = env->GetStringUTFChars(wavfile,0);
BeatTrack(filename);
env->ReleaseStringUTFChars(wavfile,filename);
return NULL;
}for my BeatTrack method, I just need the filename, then it can run, if I comment the BeatTrack(filename);, then no problem, for the java calling, of course, my BeatTrack(const *char filename) has no problem, cause I have test it,,
but I call this method in java, the error is as follows,

1) What class is "missing?"
2) Where is it?

Why my method is not working can anyone tell me plz how to write the 2darry

public class fourth {
int z;
int h;
public int[][] table(int z)(int h ){
int[][] two = new int[z][h];
for (int i=0; i < z; i++) {
for (int j = 0; j < h; j++) {
two[z][h] = (int) (z * h);
return two;
}

I hope you are looking for the following code.
Try to learn the syntax, it will help you in writting code.
     public class fourth {
          int z;
          int h;
          public int[][] table(int z, int h) {
               int[][] two = new int[z][h];

Why lookup method waits for the crossover cable to plugged in?

Hi all,
In solaris 220 machine i am facing the following problem While executing lookup method.
If the crossover cable is properly connected lookup method is working fine.
If the crossover cable is unplugged, lookup method is waiting indefinitely until the cable is plugged in. (Lookup method is not throwing any exception )
Is there any way to avoid this ?
Please help me with this issue..
Thanks in advance...

Hmmm.. well I tried the idea of establishing the connection using the Network Browser feature of Classic os9 under the brand new twin 2.7Ghz powermac I have to the old clone, and found a bunch of missing extensions inc. the Network Browser!
This is an untouched Classic OS9 install of 9.2.2 that came with the Tiger OSX that came with the machine, but using the folders and prefs. ported over from a 10.3.9 machine I was running an account on using the Migration Assistant. The Extensions manager on the new powermac cant find the file cuz it wasnt installed under Tiger, obviously...
Is Apple suggesting not to try networking in the classic layer? Is it an experiment I shoudnt bother with?
I have no idea why an OS 8.5 machine can see the Tiger tower, but not connect... and why the Tiger cant see the old 8.5 thats on the clone Im trying to directly Cat5 cable over to through the network card... this is frustrating... would be nice to get the clone without monitor to be a part of this grouping , to become a lackey/drone/server of sorts....

PrintWriter methods throw NO exceptions!

Hi,
According to the PrintWriter javadoc:
"Methods in this class never throw I/O exceptions. The client may inquire as to whether any errors have occurred by invoking checkError()."
I think this sounds strange in Java language, since it has the Exceptions mechanism...does any one know the reason why it is like this?
Regards

With unchecked exception, it will still terminate my function mid-way!
Here is a concrete example:
public void method1() {
   try {
      ... open database then read 1 entry ...
      file.println("Entry is "+x);
      method2();
      ... close the DB connection properly.
   } catch(DBException ex) {
      ... deal with the DB failure accordingly
public void method2() {
   try {
      ... open a webconnection then read 1 webpage ...
      file.println("Webpage is" + y);
      ... now close the web connection
   } catch(webException ex) {
      ... deal with the Web failure in a web-specific way
}If println throws exception (checked or unchecked), then I must wrap method1 AND method2
in yet another try/catch block. Otherwise, the function will die halfway, and my database or web connection
will be in a funky state.
By not throwing any exception (unless OutOfMemory or other dire situation),
I can write method1 and method2 without worrying about it.
And then at the end, I just check to see if all the writes succeeded or not.

GetBlobReferenceFromServerAsync (and non-async) throw an exception with 404 (not found) if the blob doesn't exist.

I'm trying to determine if a particular file exists in a blob store. I'm using container.GetBlobReferenceFromServerAsync and if the named blob does't exist I get an exception with a 404. ICloudBlob (which is returned by the method) defines an Exists method
but it's functionally useless because the GetBlobReferenceFromServerAsync method call itself throws the exception. I do get the behavior I'm looking for if I call container.GetBlockBlobReference instead but there's no async version of that method.

As I said I'd found that GetBlockBlobReference works but there's no async version of that method. I'm trying to determine IF a blob exists not create one. Since the GetBlobReferenceFromServer returns an ICloudBlob and ICloudBlob defines and Exists method
you'd assume that it could be used to determine if a blob exists. I'd argue that the fact that it throws and exception when the blob does not exist is a bug in the implementation because it makes the Exist method on the ICloudBlob object functionally useless.
Also, it seems like a fairly significant miss that there's no async version of GetBlockBlobReference. A query to a cloud resource is exactly the perfect use case for the async/await pattern.
Does anyone know of an async way to check for the existence of a blob that doesn't involve catching a 404 exception?

How to throw an exception that is not treated as error

Hi,
I have a repository manager displayed as /root/myrepository. Now when someone who's not authorized clicked it, I wish an error message will display on top in red, but not throw an exception as System Error.
Now my implementation is to throw an ResourceException in getChildren() of the node. But when the user clicked on /root/repository, a System Error screen appeared, but what I want is just an error message.
Any help is much appreciated~
I don't know how to attach the screenshots. My MSN is [email protected]
Thanks,
Ray

If you want to disallow getChildren altogether, throw an AccessDeniedException. If you want to hide specific children, just don't put them into the result list.
Best regards, Julian

Exception Thrown Here!!!

Reiner,
Tried what you suggested, still get the same results. This the 3rd development system I try this from. In all cases I generated proxies via drop and drop of the SaveData Method under StandardMaterial (BOR). Since it was just generated the MetaData should be up to date?, good suggestion thought, I could see where that might be a problem going against different backends.
My lastest attempt (I am quickly running out of ideas), was to generate a Standalone Proxy containing the SaveData method. Same Results :{
I was able to create Standalone Proxies for the other Business Objects I'm using (Characteristics, Class..etc) without a hitch. (Except for "Class", complaining about the Class name generated (Public Class Class...so I renamed to sapClass). Using the Standalone Proxy Class I might try from Visual Studio 2005 to see if I get the same results.
Also encountered another problem when trying to Add the whole BOR object StandardMaterial to the Proxy (so I would have access to a few of the Methods....this failed with some Java out of memory error....I would have to attempt this again to capture the exact error....when I get time I'll put that in another post).

Repaint() method is not working in MAC IE

Hi All
why repaint method is not working in MAC IE ? What i am doing is in one class which is inheriting Canvas class getting the keybord input then adding it to main applet.
Please help me i am trying it for whole week and i couldn't find any solution. I didn't put my code but if anyone is willing to help me i can post it.
Thanks in advancs
Shan

Hi
Thanks for your reply. Actually i wrote simple applets and those are working well.
So i did debug the code and i found that when i am running the following code in Apple MAC IE, nothing is happening in handleEvent method. Especially it is not going into the if statement (if (evt.id==401)). here i am checking for KEY_PRESS. I also tried with keyDown method but same problem in MAC IE.
I am pasting the code that is giving me problem.
import java.awt.*;
import java.applet.*;
public class testApplet extends Applet
public void init()
setLayout(new BorderLayout());
editableArea = new EditableArea();
editableArea.setBackground(Color.yellow);
add("Center", editableArea);
EditableArea editableArea;
import java.awt.*;
public class EditableArea extends Canvas
String s = "";
public boolean handleEvent(Event evt)
if (evt.id==401)
if(evt.key >= 32 && evt.key <= 255)
char c = (char)evt.key;
s = s + c;
repaint();
return super.handleEvent(evt);
public void paint( Graphics g )
g.setColor(Color.blue);
g.drawString( s,5,15);

Why is my else not working!?

     public void welcome()
          char welcomeChoice;
          InOut.println("Welcome to Dylan's Hospital records.");
          InOut.println("Would you like to proceed to the main menu? Y/N");
          welcomeChoice = InOut.readChar();
          if((welcomeChoice == 'y')||(welcomeChoice=='Y'))
               InOut.print("\n");
               mainMenu();
               else if((welcomeChoice == 'N')||(welcomeChoice=='n'));
               //exit
          else
               InOut.println("invalid response");
     }//welcomeim not an expert at java but i cannot see why this method should not work. the else is underlined and tells me "Syntax error on token "else", delete this token". But do i not need the else for the if statement to work!?

You can also do this instead of doing your "or"
statements
if(welcomeChoice.equalsIgnoreCase("y"))
Not when welcomeChoice is a char.Whoops didn't see that. Nevermind!
