Class not registered Exception while initializing a new instance of SpeechRecognizer Class
Hi,
in my Windows 8.1 Store App with HTML/Javascript I want to use Bing Speech Recognition Control.
But when I call the contructor of Bing.Speech.Recognizer Class with the language and the authorization Parameters a WinRT "Class not registered" error occurs.
What could be the reason for this problem?
I am using Visual Studio 2013.4 by the way.
Thanks in advance.

RavikumarHi,
I am not able to find sharepoint word in your post so can you please confirm that your question is related to sharepoint?
> Class not registered
For you issue, this error usually comes if you don't have DLL in proper place so add SWFToImage.dll in GAC and then add this assembly reference in your project from GAC.

Thanks in AdvanceHi,
May be of use
1. Open the visual admin at <installdrive>:\usr\sap\J2E\JC00\j2ee\admin\go.bat
2. Login is Administrator + admin-password you defined during installation.
3. Under the Server 0... node select Services->Deploy
4. Select the "Application" radio button at the bottom.
5. Check if there exists an application sap.com/tcwdtools
And the following applications are running
sap.com/tcwdcorecomp
sap.com/tcwddispwda
sap.com/tcwdtools.
Last thing was their any errors in the installation.

GeneratePDFService : An unexpected exception while resolving a new connection to an Adobe Service.
Hi,
I'm using LC ES on Windows XP, turnkey installation.
I've created a workbench process that suppose to convert word document to pdf using GeneratePDFService. When I invoke the process it fails with the next error:
2008-04-28 09:30:32,781 ERROR [org.jboss.ejb.plugins.LogInterceptor] RuntimeException in method: public abstract com.adobe.native2pdf.bmc.ResultStruct com.adobe.pdfg.bmc.invoker.NativeToPDFInvokerLocal.convertPDFMToPdf(java.lang.String,java .lang.String,java.lang.String,int,byte[],java.lang.String,byte[],com.adobe.native2pdf.bmc.

Also I get the Windows error message :PDFGenerator Process Launcher has encountered a problem and needs to close.
Any Ideas ?
Thanks!Nevermind everyone. I figured out that I can do a manual change and just add the user to one of the groups and everything should be ok. Something happened silently within the system that caused it.

Kcmond: krb5kdc Not a directory while initializing krb5
These errors are appearing every 3 seconds in my system.log
Oct 6 23:25:53 Oc com.apple.kdcmond[88]: krb5kdc:
Oct 6 23:25:53 Oc com.apple.kdcmond[88]: Not a directory while initializing krb5
I posted on this same subject back in April on very different hardware (http://discussions.apple.com/thread.jspa?threadID=1468639&tstart=0), but never resolved it. I never managed to fix it, and it's still happening.
I have no explicit use for kerberos (I'm not using LDAP or anything like that), so anything it's being used for is standard system stuff.
Any ideas?Problem went away after a system update several years later.

Exception while getting the server instance. Stateless bean problem
Hi,
New to OC4J, I'm moving an ear that was running ok under jboss.
1- The wep app deploys. This is a piece of code inside the init() method of a struts plugin:
System.out.println("0");
AddressFacadeHome addressFacadeHome = HomeFactory.getAddressFacadeHome();
System.out.println("1.0");
AddressFacade addressFacade = addressFacadeHome.create();
System.out.println("1.5");
2- The code is run when the web app is initialized. This is the error message I get. system.out show that the error occurs on addressFacadeHome.create().
AddressFacade is a remote/local stateless bean. HomeFactory returns the jndi lookup/narrow of the remote object.

My guess is that it's a jaas issue (because i see security and getCurrentUser), but at init time, no user is authenticated.
Any clue would be very much appreciated. Let me know if I can provide anything else, such as deployment descriptors.
Thanks,
Christophe.After spending some time on this, I looked at the source code for com.evermind.server.ThreadState
This is the code that throws the exception:
if(applicationThread != null && applicationThread.httpHandler != null && applicationThread.servletInfo != null)
try
server = applicationThread.httpHandler.request.getApplication().getApplication().getServer();
catch(Throwable t)
System.out.println("caught exception while getting the server instance " + t.getMessage());
t.printStackTrace(System.out);
It looks like this method expects a httpRequest, and would find null because I'm in the servlet.init()
(at least, that's my interpretation)
I tested my code (the remoteFacade.create()) inside of a jsp, and it worked...
So, the next logical question is:
Can I make EJB calls from within the init method of a servlet? (or more specifically from a struts plugin, which I believe should be more or less the same thing)
If so, do I need to take extra steps?
Again, any experience/help on this will be much appreciated.
Thanks,
Christophe. -
Class not Found Exception while running an EJB
I have created and published a EJB in Oracle 8i (in a particular
schema) by running the deployejb tool supplied. The ejb was
published successfully. On running the client program I get an
error saying that the mybeans's HomeHelper class cannot be
found. This error occurs when there is a lookup to the home
interface of the bean. The exception thrown says Reasons are
unknown. On checking the objects of type 'JAVA CLASS' I found
that the homeHelper class object had been created automatically

JCOM - class not registered exception
Has anybody used JCOM successfully?
I'm trying to access a COM component from a java client using JCOM.
Component is registered locally (I can succesfully access it via other
clients). I created the Java wrapper classes with the com2java tool, but
when I try to use them, I get AutomationException - class not registered
error. CLSID in the generated wrapper class seems correct. Any ideas?
Thanks,
LeventHi Levent,
I don't think that the EJB discussion area is the best place for you to get
answers to this question. Maybe "tools" or "environment".

While there can be many causes for this generic error message, in my case the first parameter or ddwrt:DataBind function inside the SharePoint:FormFields element was
'i' and I was working with an Edit Form. Changing it to
'u' as it was with every other FormField fixed the issue.
<SharePoint:FormField runat="server" id="ff1{$Pos}" ControlMode="Edit" FieldName="Esittaja" __designer:bind="{ddwrt:DataBind('u',concat('ff1',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Esittaja')}"
/>
Explanation:
DataBind operation type parameters (the first parameter) are listed below:
'i' stands for INSERT,
'u' stands for UPDATE,
'd' stands for DELETE.

Hi,
We have a requirement to purge the Azure WADLogs table on a periodic basis. We are achieving this by using Entity group transactions to delete the
records older than 15 days. The logic is like this.
bool recordDoesNotExistExceptionOccured = false;
CloudTable wadLogsTable = tableClient.GetTableReference(WADLogsTableName);
partitionKey = "0" + DateTime.UtcNow.AddDays(noOfDays).Ticks;
TableQuery<WadLogsEntity> buildQuery = new TableQuery<WadLogsEntity>().Where(
TableQuery.GenerateFilterCondition("PartitionKey",
QueryComparisons.LessThanOrEqual, partitionKey));
while (!recordDoesNotExistExceptionOccured)
IEnumerable<WadLogsEntity> result = wadLogsTable.ExecuteQuery(buildQuery).Take(1000);
//// Batch entity delete.
if (result != null && result.Count() > 0)
Dictionary<string, TableBatchOperation> batches = new Dictionary<string, TableBatchOperation>();
foreach (var entity in result)
TableOperation tableOperation = TableOperation.Delete(entity);
if (!batches.ContainsKey(entity.PartitionKey))
batches.Add(entity.PartitionKey, new TableBatchOperation());
// A Batch Operation allows a maximum 100 entities in the batch which must share the same PartitionKey.
if (batches[entity.PartitionKey].Count < 100)
batches[entity.PartitionKey].Add(tableOperation);
// Execute batches.
foreach (var batch in batches.Values)
try
await wadLogsTable.ExecuteBatchAsync(batch);
catch (Exception exception)
// Log exception here.
// Set flag.
if (exception.Message.Contains(ResourceDoesNotExist))
recordDoesNotExistExceptionOccured = true;
break;
else
break;
My questions are:
Is this an efficient way to purge the WADLogs table? If not, what can make this better?
Is this the correct way to handle the "Specified resource does not exist exception"? If not, how can I make this better?
Would this logic fail in any particular case?
How would this approach change if this code is in a worker which has multiple instances deployed?
I have come up with this code by referencing the solution given
here by Keith Murray.Hi Nikhil,
Thanks for your posting!
I tested your and Keith's code on my side, every thing worked fine. And when result is null or "result.count()<0", the While() loop is break. I found you code had some logic to handle the error "ResourceDoesNotExist" .
It seems that the code worked fine. If you always occurred this error, I suggest you could debug your code and find which line of code throw the exception.
>> Is this an efficient way to purge the WADLogs table? If not, what can make this better?
Base on my experience, we could use code (like the above logic code) and using the third party tool to delete the entities manually. In my opinion, I think the code is every efficient, it could be auto-run and save our workload.
>>Is this the correct way to handle the "Specified resource does not exist exception"? If not, how can I make this better?
In you code, you used the "recordDoesNotExistExceptionOccured " as a flag to check whether the entity is null. It is a good choice. I had tried to deleted the log table entities, but I used the flag to check the result number.
For example, I planed the query result count is 100, if the number is lower than 100, I will set the flag as false, and break the while loop.
>>Would this logic fail in any particular case?
I think it shouldn't fail. But if the result is "0", your while loop will always run. It will never stop. I think you could add "recordDoesNotExistExceptionOccured
= true;" into your "else" block.
>>How would this approach change if this code is in a worker which has multiple instances deployed?
You don't change anything expect the "else" block. It would work fine on the worker role.
If any question about this issue, please let me know free.
