InvalidProgramException thrown from async version of methods in release mode

Hi,
I am working on a small library and refactored it to use code contracts. I'm almost done and started playing with the contracts options. I noticed that if I select Full runtime contract checking - all is fine, but if I select any other option, e.g. release
requires, 5 of my unit tests fail by throwing InvalidProgramException from within an asynchronous protected method with Requires<Exn>:
protected virtual async Task LoadHashToValidateAsync(
Stream encryptedStream)
Contract.Requires<ArgumentNullException>(encryptedStream != null, "encryptedStream");
Contract.Requires<ArgumentException>(encryptedStream.CanRead, "The argument \"encryptedStream\" cannot be read from.");
Contract.Requires<ArgumentException>(!ShouldEncryptHash || PrivateKey != null, "The certificate does not contain a private key for decryption.");
If I revert the option to Full checking - all is fine. Also the synchronous version of the same method with the identical Requires doesn't have this problem.
Can you please help how to fix the problem.
Thanks
Val

ABAP proxy method change - from which version?

Hi,
for some new abap proxies when generating them inside
SPROXY methods like EXECUTE_ASYNCHRONOUS
are no longer available - it's fine I can use the message interface name
as the method and the call works fine
question:
but does any of you know from which version this works like that?
any SP level or patch level? (any OSS note mentioning it maybe)?
I just need the document (or link) that mentions - from this version
in abap proxies you need to use MI as the method's name
that'a all
thank you,
Regards,

http://mypigenie.com XI/PI FAQ

It came with SAP_BASIS SP14, the same release were SAP introduced the proxy generation for PI 7.1 service interfaces with several operations. This was the reason for the change.
The PI systemis not relevant, but the SP level of the component SAP_BASIS of the application system.
I am sure if there is any documentation availble for this change. I read about this change in SDN forum

Differentiating between same exception thrown from 2 different methods

Suppose I have a class CodeDAO which has 2 methods who both throw SQLException
public int getLocationCode(String locationName) throws SQLException;
public int getDepartmentCode(String departmentName) throws SQLException;Now I have a business method in which I have to use both of the above DAO methods.
public int process() {
   try {
      CodeDAO codeDAO = new CodeDAO();
      int locationCode = codeDAO.getLocationCode("NJ");
      int departmentCode = codeDAO.getDepartmentCode("Sales");
   catch (SQLException e) {
}If SQLException is thrown how will I know if it is thrown by the getLocationCode method or getDepartmentCode method?
What are the different choices I have in differentiating between same exception thrown from different methods? And which choice do you guys prefer?
Thanks

Put each method invokation in its own try/catch block.Or in fact not use SQLException, but exceptions that are unique.So each DAO method has its own exception?
public int getLocationCode(String locationName) throws GetLocationCodeException;
public int getDepartmentCode(String departmentName) throws GetDepartmentCodeException;would not that means I have to create a lot of exception classes?
Edited by: srhcan on Aug 9, 2012 2:54 PMLet me ask you this, what do you plan to do in the catch block? Do some sort of recovery? rollback? If it is just for logging purposes, I am pretty sure the exception message will give you enough information to find out where the error was.* I would like to give user a specific message based on which method fails. So if getLocationCode("NJ") fails the message can be: Unable to find code for Location "NJ". And if getDepartmentCode("Sales") fails the message can be: Unable to find code for Department "Sales".
* I would like to print the exception's stacktrace in the log file.
* I may do a rollback depending on if its an INSERT/UPDATE/DELETE statement.Well, in that case why not log it in the DAO methods themselves...inside getLocationCode and getDepartmentCode. Instead of trying to do the recovery/logging in the process method, do it in the individual dao methods. The calling classes should not be responsible for logging/recovery etc. It should be done in the DAO classes themselves and the DAO method should return an appropriate message/code to the consumer tier classes indicating the status of the transaction. Just my 0.02$.

AssertionError thrown from IIOPInputStream.read_value()

Attached is an example of a stacktrace we are getting when we attempt to communicate
with weblogic from eGate using an RMI call. This error occurs on more than one
transaction, but not every time we run the transaction. We can run a data file
through, and have it work fine, then the run the same file through, and we get
the previous stack trace. I have searched through the online documentation, and
have been unable to find an example of this error being thrown from the 'weblogic.iiop.IIOPInputStream.read_value()
method. Do you have any ideas as to what could be causing this problem?

How to catch Exception in backingbean which is thrown from the Model layer.

Hi,
JDev Ver: 11.1.1.2.0
In my application there are two layer viewcontroller & model.
In model layer I have created JPA service facade which does the database operation like persist, merge & remove entity.
I am calling this service facade method from backing bean via below standard code.
public static Object invokeMethod(String methodName, String mapKey,
Object object){
BindingContext bcx =
DCUtil.getBindingContext((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest());
JUFormBinding bc1 = (JUFormBinding)bcx.getCurrentBindingsEntry();
FacesCtrlActionBinding reassignOperationBinding =
(FacesCtrlActionBinding)bc1.findControlBinding(methodName);
if (mapKey != null && object != null) {
Map params = reassignOperationBinding.getParamsMap();
params.put(mapKey, object);
Object result = reassignOperationBinding.execute();
return result;
This is a static method which I am calling from backingbean to invoke service facade persist, merge or remove entity method
I have written throws in all the methods signature of service facade.
The exception which is thrown from the service facade are not comming back to backingbean catch block.
Is there any way to catch this exception in backingbean.
regards,
devang

Hi,
2 things to check
1 - does reassignOperationBinding has errors. You can check on the component
2 - does the exception show on the binding layet. See the Fusion Developer guide for how to define an error handler on the databindings.cpx file

I don't have any idea to offer on what the problem is. However, here are some suggestions:
Perhaps you can provide an example of your code and/or a more through description of what it does so someone might see something wrong with the code.
I assume you print out the entire stack trace using somthing like this, so you can get the entire stack trace:
} catch (Exception e) {
e.printStackTrace();
and not something like this:
System.out.println( e.getMessage());
You can also consider peppering your code with System.out.println() statements (or write to the log file) to get a better understanding of whats going on and where it crashes.
What is jgps.RTI.jar? Is that a jar file you created or a vendor jar file? If its a vendor jar file, you might research their web site on how to use it.

This exception is never thrown from the try statement body

try {
               SimpleFileReader.openFileForReading("fileName.text");
          } catch (FileNotFoundException fnfe) {
               System.out.println("");
          }This is part of a method, if that helps. In Eclipse I get the error message "Unreachable catch block for FileNotFoundException. This exception is never thrown from the try statement body." I saw another post similar to this one, but it's not quite clear what the solution is. Could anyone clarify for a beginner?
Thanks

It actually does if the file it's opening is not really a text file, or if it's read-protected. Or is that where I'm going wrong? I'm just trying to open the file's name(already in the field) and know that it is .text or will return the error.

How to convert llb from LabVIEW version 8 to 7.1

Can someone tell how to convert the llb from LabVIEW version 8 to version 7.1?
I hope to sent the program to the others, but the other side are using LabVIEW version 7.1 but not version 8.0.
I know I can save to VI file as previous version, but it contains severals of VI in the library, it is quite time consuming.
Can everyone sugguest any method or solution to solve my problem.
Thanks.

Hi anson,
it will run also in LV7.1 - but you should check those warnings (probably things not/differently supported by LV7.1...) anyway!
Best regards,

IllegalMonitorStateException Thrown From Synchronized Block

Greetings,
We recently had a case where a java.lang.IllegalMonitorStateException was thrown from section of code (in activemq) that I'm 99.9% sure was properly synchronized. Has anyone ever seen this exception thrown when the object whose wait method is being called is currently owened (via. a synchronized block)?
The code that this exception occurred was in the backport-util-concurrent library. A get method (which is synchronized) call was made to a FutureTask instance which (eventually) calls Object.wait(). This call threw the exception. Below is the FutureTask code.
public synchronized Object get() throws InterruptedException, ExecutionException
waitFor();
return getResult();
private void waitFor() throws InterruptedException
while (!isDone())
wait();
}And the stack trace on the exception was:
ERROR - 21/2 08:56:41 - Failed to checkpoint a message store: java.lang.IllegalMonitorStateException - org.apache.activemq.store.journal.JournalPersistenceAdapter 395

There seem to be some difficult to reproduce bugs in JDK 6 relating to hotspot compilation (and maybe synchronization). A few threads worth checking out:
http://forum.java.sun.com/thread.jspa?threadID=5251785&tstart=0
http://forum.java.sun.com/thread.jspa?threadID=5262404&tstart=0
My own bug report (this one is reproducible): http://www.blinkenbyte.org/jvm/hotspot_bug_reviewid_1085121.html
Which reminds me, I need to get around to submitting an update to the report.. disabling HotSpot compilation on the problematic method made the problem go away in my case...
If at all possible to turn this into a test case, please do so and submit a bug report to Sun. Somehow Sun needs to pay attention to this problem, but I haven't even got a bug id on my problem despite it being 100% reproducible.

Urgent....How can i redirect to my jsp page from servlet in init() method..

How can i redirect to my jsp page from servlet in init() method..Becoz that servlet is calling while server startsup..so im writing some piece of code in init() method..after that i want to redirect to some jsp page ...is it possible?
using RequestDispatcher..its not possible..becoz
RequestDispatcher rd = sc.getRequestDispatcher("goto.jsp");
rd.foward(req,res);
Here the request and response are null objects..
So mi question can frame as how can i get request/response in servlet's init method()..

Hi guys
did any one get a solution for this issue. calling a jsp in the startup of the servlet, i mean in the startup servlet. I do have a same req like i need to call a JSP which does some data reterival and calculations and i am putting the results in the cache. so in the jsp there in no output of HTML. when i use the URLConnection i am getting a error as below.

Is it possible to migrate the app from latest version to older version

Hi all,
I have a adf application in jdeveloper 11.1.1.4.0.Due to some issues i have to do it in jdeveloper 11g release 2 (11.1.1.2.0).Is it possible to migrate the application from latest version to older version of jdev.
Thanks.

It's not officially supported, but you can try a couple of things - first open the application in the old version and see if it works.
If it doesn't you can try creating a new application in the old version and then use the create project from existing source option to map to your existing code.
This all of course assumes that you didn't use features in the new version that are not available in the old version.

Project (movie) not showing up in trash when I delete it from iMovie (version 10.0.4). Thus, I can't figure out how to permanently delete it from the hard drive. I'm running out of hard drive space fast! Any ideas?

I am trying to delete a project (movie) from iMovie (version 10.0.4). I successfully deleted it but it isn't then showing up in my trash items to delete it there. Thus, I'm running low on my storage space. Any ideas?

It's an iMovie Library file that you need to search for. By default iMovie Library files are in the Movies folder.

NO EXCEPTION IS THROWN FROM THE PERSIST

We are using Glassfish and MySQL. When we do a persist with a bad object/query, internal DB errors are NOT being reported back to the caller in any way, but Glassfish knows that the error occurred. Here is a schematic of the situation:
     Glassfish starts a CMP transaction and calls our bean
          Inside the bean we have code like this:
               obj = (a new object that will cause a DB error when persisted)
               try {
                    entityManager.persist(obj)
               } catch (Throwable t) {
                    report to the user that the throwable happened
          bean returns
     Glassfish manages CMP transaction
What we see is the following:
     - The persist has an internal failure and generates error messages in the Glassfish system.log file.
     - NO EXCEPTION IS THROWN FROM THE PERSIST, so the application code thinks that the persist completed correctly
     - At the end of the bean operation, Glassfish (correctly) rolls back the transaction.
At the user level the result is that the request succeeds but nothing is put into the Database!
We are not asking about the cause of the DB error. From reading the system log we know what happened and can fix it. Our problem is that problems in our field-deployed systems cannot be detected by the application code so failures cannot be reported to the user.
The critical question is:
     Is there a way for the application code in the bean to see that an error occurred?
By the way, we also have a secondary question: Why is the erroneous persist tried 6 times before deciding it won't work? Is there an option somewhere that says to try 6 times?
The Exception as reported in the system log (only one copy of it) is included below.

This is because the persistent context is not synchronized with the database until the commit is being executed.
You might 'force' this by calling entityManager.flush() right after the call to persist(...).
Or you register a transaction synchronizer and check the transaction status on afeterCompletion().
