JPA with GridRead configuration throws the exception

Hi,
I used the JPA entities and tried to cache the entities with GridRead configuration. I deployed the following share libraries.
coherence3.6.jar
toplink-grid-11.1.1.5.0.110305.jar
active-cache-1.0.jar
Oracle Weblogic PS5
and eclipselink is in the classpath of the application.
When I execute the read query, i faced the below exception.

Hi,
have you tried to urlencode the hash char?
Might be interesting as well if the problem also occours when you point to a local script in your url. The script should then contain a static link to your xml file.

Problems with Tick Configuration on the x-axis in an XY graph

I have set up an XY graph in LabView 2012. The plot area is 1000x750. The x range min is -15. x range max is 15. y range min is -20. y range max is 20. The x and y range increments are 1. The x and y range minor increments are 0.2. The x range start is -14.
When I run the vi the graph comes up in the proper size. The minor grid lines for both the x and y ranges are there at every 0.2 units. The major grid lines are correct for the y scale at every 1 unit. The x scale has a major grid lines at -14 and 14, but in between the major grid lines are at -12, -10, -8, -6 ,-4, -2, 0, 2, 4, 6, 8, 10, and 12. This is incorrect. I expect to see them for every 1 unit as they are on the y scale.
I have change the x range start to -15 keeping all other properties the same. When I do this the major grid lines on the x scale are at -13, -11, -9, -7, -5, -3, -1, 1, 3, 5, 7, 9, 11, 13. Again every 2 units.
I have tried changing the width of the graph along with many of the other properties. Nothing has worked.
Why is this happening? Why does the y scale set up properly but the x scale does not?
I have attached a screenshot of the property node.
Any help is appreciated.

Two things to try:
Use a smaller font for the X-axis.
Change the display format.

A vertical axis needs much less space for a tick than a horizontal axis, so that's expected. We really need to see a simplified version of your actual VI (delete everything except the graph and the property nodes).

Get-ChildItem with -LiteralPath is throwing "The specified wildcard character pattern is not valid" when filenames contain brackets

I'm trying to get a list of folders in a hierarchy that don't contain any mp3 files. (The goal here is to eventually clean up all the "empty" folders that only have album art, thumbs.db, desktop.ini, etc. files left). So I wrote a quick PowerShell
command to try to do this. But it doesn't seem to be working.
I already checked out this thread <Get-ChildItem
SomeFile[].txt occurs error because of the [brackets]: "specified wildcard pattern not valid"> and I think I'm using LiteralPath correctly. Any other hints for troubleshooting this problem? Here's the command I'm using.
Get-ChildItem -Recurse -Directory | ?{
@( @(Get-ChildItem -LiteralPath $_.FullName -Recurse) | ?{
$_.Extension -eq ".mp3"}).Count -eq 0 }
This is on the latest version of PowerShell found in Windows Technical Preview.

Fair enough, but it still doesn't answer the original question- why isn't this working with -LiteralPath when the path contains brackets?
Get-ChildItem -Recurse -Directory | ?{
@( @(Get-ChildItem -LiteralPath $_.FullName -Recurse) | ?{
$_.Extension -eq ".mp3"}).Count -eq 0 }

Problems with jdbc configuration in the config.cfg file

Hi to all,
I need to change my oracle database ucm user from idc_orcl to idc_oracle for example but i dont know how to generate the encrypted password of the user in the config.cfg file
if I let the configuration like below (plain text password and JdbcPassword commnetend) it works.
But it is not an accepted solution for me, leaving the password in plain text.
+#Database Variables+
JdbcDriver=oracle.jdbc.OracleDriver
JdbcConnectionString=jdbc:oracle:thin:@localhost:1521:ucm
JdbcUser=idc_oracle
JdbcPassword=idc_oracle
+#JdbcPasswordEncoding=Intradoc+

Is there any doc or example related.
Thanks in advance

Export with BiarEngine.jar works, using the API it throws an exception

Hello,
I'm using BiarEngine.jar to export from my CMS. it works fine.
Now I want to use the API to get someting more handy, but I receive an exception (NoSuchFieldError) as if I had a mismatch between versions.
I'm stuck with it, if somebody has an idea...
Thanks a lot.

Here is the java code:
IExportOptions oExportOptions = BIARFactory.getFactory().createExportOptions();
oExportOptions.setIncludeSecurity(false);
oExportOptions.setIncludeDependencies(true);
oExportOptions.setCallback(

          public void onFailure(int id, BIARException biarException) {...};
BIAROutput oBIAROutput = new BIAROutput( oEntrepriseSession, "c:\myFile.biar", exportOptions );
At this point it throws the exception:

It is possible. I'm going the same way here. However, I remember I needed to contact support because it was not a standard feature of the Ant task. They provided me with the patch that allowed me to use -configSubProjects parameter in export.

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?

Throwing or handling the exception.

Hi,
Which is the good idea.
*1 .* throwing the exception to the caller method.
*2 .* handle the exception at the save place.(with the help of try/catch).
Any pointer will be highly appreciated.
Regards,
Alok

Usually #1, though sometimes you'll wrap it in an exception more appropriate for that layer.
To handle the exception, you have to truly handle it.You have to provide a correction for whatever went wrong. That might mean retrying or using some default value or calling some other "safe" algorithm. If you can't actually fix it, you have to throw something to let the caller know what went wrong. It's then up to him to determine whether to handle it or throw it to his caller.

How to Throw an Exception in a SapServer

Hello,
We have successfully implemented SAPServer in our external process.
The only thinks that doesn't work perfectly is that we can't throw an exception in the implementation of remote function module.
The ABAP Program that is calling our fontion waits on expetion 0, 1, 2, 3 and 4. But when we throw the exception like this : throw new RfcException( "Error" );
the ABAP catch this exception, but as exception 4 (others) and not as 3 (Error)
Can someone help. Thanks

Hello
Thanks for the answer.
In the while we tried the following:
RfcAbapException( "ERROR" );
but it doesn't work.
The solution was to call this method with 2 parameters:
RfcAbapException( "ERROR", "Some error text...");
And now OK.

I dont want to throw an exception !!

Hi,
          I have a stateless session bean, that in turn calls BMP entity bean. The
          transaction attribute for session bean is Required and that of entity bean
          is Supports.
          Now if some database error occurs, I want to catch that exception in the
          stateless bean, and dont want to rethrow it. How can I do it. Weblogic still
          throws the exception.
          The code of session bean looks something like this :
          try
          // Call entity bean
          catch (Exception e)
          // Dont do anything !!
          on the client program, that calls the session bean, am getting this
          exception :

          What am I doing wrong here ? The idea is, I dont want the client to know

Amit,
          I believe that what is actually happening here is that the transaction is
          not actually being rolled back until the session bean method, which is
          participating in the transaction, is completing. I too am having this
          problem and currently have not found a solution short of adding an extra
          layer which is not an option. You also appear to be having another problem
          with the transaction upon which I cannot comment.
          Any help would be greatly appreciated.
          Regards

Regarding the exception

java.security.AccessControlException: access denied (java.util.PropertyPermission user.dir read)
The following exception was thrown while displaying the data from XML file in Applet window. The applet window shows the exception above.
I placed all the files (.java, .xml and .html) in same folder but still the exception continues. What can I do for?

This has nothing to do with JSP/JSTL.
The exception simply tells you that JVM is not allowed to read the "user.dir" system property. This is a security issue/configuration at the client side. Most probably you need to sign your applet to get it to work. Google "signed applet" for details.

Is it okay practice to have a constructor throw an exception?

Or is it just plain bad practice and it's better to catch it instead.

I don't know if there is anything wrong with the/a
constructor throwing an exception. It is a way to
inform the user that something "bad" occurred during
creation of the object.
I usually don't do it. I have my constructor call a
method that encapsulates the code that may generate
an error.
public class MyExample
public MyExample()
try
aMethodThatPerformsIO();
catch(IOException ioe)
n ioe) {ioe.printStackTrace();}
private void aMethodThatPerformsIO() throws
ows IOException
//blah
Presumably aMethodThatPerformsIO initializes the state of the MyExample being constructed, yes? That's why you call it in a ctor, yes?
MyExample myEx = new MyExample(); // exception is thrown, stderr gets some bytes, object is not properly initialized, BUT...
myEx.doSomethingThatAssumesValidState(); // ...this still executes (or tries to) despite the assumption about valid state being violated like godlie at a biker bar.I'd rather have the ctor throw the exception, but that's JMAO.

One method throw many exception

7. Create three new types of exceptions. Write a class with a method that throws all three. In main( ), call the method but only use a single catch clause that will catch all three types of exceptions.
Ok, I am learning java language from bruce eckel book. That is the exercise. I m having dificulties.
How can one method throw more than one exception?
class Satu extends Exception
   Satu() { }
class Dua extends Exception
   Dua() { }
class Tiga extends Exception
   Tiga() { }
class ThisIsIt
   public void f() throws Satu, Dua, Tiga
      throw new Satu();
      throw new Dua();
      throw new Tiga();
public class Enam
   public static void main( String[] args )
      try
      ThisIsIt a = new ThisIsIt();
      a.f();
      catch( Exception d )
      System.out.println( "Doing something here" );
}That code won't even compile because :
Enam.java:21: unreachable statement
throw new Dua();
^
Enam.java:22: unreachable statement
throw new Tiga();
Do I interpret that question wrong????

The problem you have is that when the code comes to the first 'throw' command it will throw the exception and exit the method (like a return does) so the code after will never be reached. In order to test your code you need to put some 'if's around the throws or give it a parameter from the console. eg.class ThisIsIt
    public void f(int errorType) throws Satu, Dua, Tiga
        if (errorType ==1)
            throw new Satu();
        if (errorType ==1)
            throw new Tiga();
        if (errorType ==1)
            throw new Dua();
}Ted.

JPA with GridRead configuration throws the exception
