Got exception while using a command parameter in subreport

Hi All,
I've make a report with some subreport full ODBC based(master report and all the sub report have a ODBC database source).
The main report has a parameter 'a'. I linkened the parameter 'a' from the main report to the sub report and used it as a parameter at the command (query).There are no problems when I work at the crystal designer.
For my purposes i need to change the datasource at runtime to JDBC. If i try to change at runtime the dasource using the standard ChangeDataSource method (the same in CRJavaHelper.java file) i've got the exeception :
JRCCommunicationAdapter: detected an exception: java.lang.NullPointerException
at com.crystaldecisions.reports.reportdefinition.ParameterFieldDefinition.qJ(Unknown Source)
at com.crystaldecisions.reports.reportdefinition.ParameterFieldDefinition.qL(Unknown Source)
The Problem is because the subreport use the parameter as a command
After that I tried Ted solution mentioned in the thread:
Runtime Change datasource problem with JDBC report
but with no success, after that i continued investigating and i found that the report parameter field defined inside the command of the subreport was changed and no more linked to the subreport parameter field.
Thanks

Exception while using unit of work commit

Hi,
I have using this code to create a object
KbAdAlerts alert = new KbAdAlerts();
alert.setAlertId(kmData.getAlertId());
alert.setAlertDesc(kmData.getOutcome());
alert.setAlertLastRevisionDate(KmUtils.convertReviewDate(kmData.getReviewDate()));
alert.setAlertType(kmData.getAlertType());
System.out.println("Alert Object :" + alert);
KbAdAlerts alertClone = (KbAdAlerts) uow.registerObject(alert);
System.out.println("Clone Alert:" + alertClone);
uow.printRegisteredObjects();
uow.commit();
I am getting exception while using uow.commit(). I have gone into alert object and everything seems to be fine.
Could you help me in this issue.

Hi,
I am having a similar problem that results in this stack trace. The funny thing is that it occurs after a session.logout/login and re-read of the object I'm trying to update. The other thing is that if I remove objects from the transaction it just happens somewhere else - on a different object/descriptor. I am attempting to upgrade from 9.03 runtime to the 10.0.3.1 builder/runtime. I am connecting to a Sybase 12.5 db.
Any ideas on this one?
Thanks,
Bret

The issue was improper privleges of the Nested Types in the schema to which my server was connecting. Once proper privelges were given, everything started working just fine ...

Dabase link while using copy command in Oracle 9i

Hi,
Is it must to have a database link while copying data between two databases in Oracle 9i using COPY command?
I am using the copy command like following:
SQL> copy from xxx/xxx@xyz to abc/abc@stu insert Table using select * from Table
Database link is always required in Oracle 9i to copy data ?
rgds,
Karna

When you use the copy command, all you need is that both databases are in the tnsnames.ora file and you can commect using the username/password#sid string. The copy command doesn't use the DBlink.

Getting Errors while using IMPDP command in UNIX

Hi All,
My work involves Refreshing of DB with latest Data. For this i am using IMPDP command to import the data. But Every time during refresh i will get errors saying like "oracle Generated Errors Oracle Not available".
I don't know what is the reason for getting this error, and that too my db goes down after this error. Again i will startup the db , and i will try my luck to complete the process.
so please tell me what are the actual problems that might cause the IMPDP to be failed.
with one advise , i have stopped my listener and done the importing, Interestingly this time IMPDP works without errors. But this is also not always working.
But i feel that every time starting and stopping the listener is not the correct solution.
so please help me in this regard.
Regards
Naveen R.

The error i am getting is...

Coppy commit while using copy command

I am seeing the following message when I used Copy command in Oracle 9i.
Array fetch/bind size is 15 (arraysize is 15)
Will commit when done (coppycommit is 0)
Maximum long size is 80 (long is 80)
Could someone tell what does it mean and is there any harm with coppycommit being ZERO ? If so how we could change it ?
DBA was telling the following:
In using the copy command in oracle, not specifying 'arraysize' and 'copycommit' attributes for large records will blow up the rollback segment and return errors.
thanks,
Karna

Datatype problem while using copy command

Hi all,
I an using copy command to copy data
SQL> copy from xyz/abc@xxx to aaa/sss@aaa create Table1(Name,duration) using select * from Table2The problme is in Table2 duration is like 4.5,but when after copying in Table1 it is coming as 4 .
Could someone help me in fixing this ?
rgds,
Karna

try not defining the columns first, the create will do that.
copy from xyz/abc@xxx to aaa/sss@aaa create Table1 using select * from Table2
I am assuming the table2 only contains the two columns.

Bad Record MAC. exception while using urlConnection.getInputStream()

All,
In my SAP J2EE instance, from filter I am trying to do get data from an url (protocol is https).
For this I am using urlInstance.openConnection() after that urlConnection.getInputStream() and then reading from this input stream.
When I use http protocol, everything works fine. But with https, during urlConnection.getInputStream(), I get an exception saying "Bad Record MAC".
I tried to execute the same code in a standalone java program. It went fine with both http and https.
I get this error only when I run in SAP J2EE instance and only with https.
From the exception trace, I can see that while running in J2ee engine, the URLConnection instance is org.w3c.www.protocol.http.HttpURLConnection.
When I run a standalone program from command prompt, the instance is com.ibm.net.ssl.www.protocol.https.r. This runs without any issues.
I understand that these instances are different due to different URLStreamHandlerFactory instances.
But I didnt set the factory instance in either of the programs.
1. Is the exception I get is simply bcoz of instance org.w3c.www.protocol.http.HttpURLConnection?
2. In that case how can I change the factory instance in j2ee engine?
Please help.
Thanks.

May be my question is too complex to understand. Let me put it simple.
After upgrading to NW 7.01 SP5, an existing communication between SAP J2EE engine and a 3rd party software is not working.
After a lot of debuggin I came to know that its happening at the filter we implemented to route the requests through the 3rd party authentication system.
At the filter exception is coming from org.w3c.www.protocol.http.HttpURLConnection.getInputStream.
This instance of HTTPURLConnection given by protocol handler factory(implementation of URLStreamHandlerFactory) which SAP is considering by default. I want to replace this protocol handler with another handler as I see no problems running the same program outside SAP J2EE instance.
Can we change this protocol handler factory? Where can we change it?

Exception while using RSA BSAFE CryptoJ in Weblogic 7.0 (SP2)

I need to verify the digital signature in the application (Web Tier - Servlet)

Reponses are highly appreciated.

Weblogic is using RSA Crypto-J 3.3.1 The easiest solution is probably to modify
the signature verification code to use 3.3.1 api-s. The alternative solution would
require writing your own classloader for the application that would load BSAFE
classes from your jar.

Exception while using JDIC

I used jdic-0.9.1 for registering the file type association of the file format that i have created. While executing the code for registering the association it throws the following exception.
java.lang.UnsatisfiedLinkError: no jdic in java.library.path

I have given the code here...

          icubeAssociation.addFileExtension("icube");
          icubeAssociation.addAction(new org.jdesktop.jdic.filetypes.Action(
                    "open", "Path of application goes here"));
          icubeAssociation.setIconFileName("The icon file goes here");
          try {
               associationService.registerUserAssociation(icubeAssociation);
          } catch (AssociationAlreadyRegisteredException e) {
          } catch (RegisterFailedException e) {
}

That is because it can't find the jdic dll file. If
you're using Netbeans, you can just copy over
jdic.dll file over to where jdic.jar file is located
(and you have jdic.jar included in the library in
your project). If you're not using Netbeans (or other
IDE), you need to set java.library.path system
property, but I don't recall the complete steps.. you
can do a search for 'how to load dll in java'.
Good luck,
MaxI am also using NetBeans 5.5 and trying to work with JDIC, to no avail. I continue to get the following exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jdic in java.library.pathAnd there is no jdic.dll nor jdic.jar that exists, this while doing a CVS checkout per instruction of jdic into its own project "JDIC_WIN32" working alongside my "GUI" project.

How to handle "The specified resource does not exist" exception while using entity group transactions to purge WADLogs table

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.

Will
