EJB ClassCastException Retrieving from Collection in same AppServer

I am experiencing a weired Problem.
I am passing a Collection of IdNameTO Transfer Object from My EJB Client(JSP) to EJB.
At Server Side EJB is able to get the Object From Collection but when it does a Cast to convert the Object back to IdNameTO I get ClassCastException on IdNameTO.
This problem happend only when Both Client and Server(EJB) are deployed on Same Application Server(WebSphere) i.e. same Virtual Machine. If Both Client and EJB are deployed on separate Servers then I don;t get any Exception.
If I form a collection of IdNameTO in EJB and pass it to EJB Client then even on same Server I don't get any exception.

Order of rows retrieved from collection

hi -- If I do not specify an ORDER BY clause when selecting rows from a collection, is
there any pre-defined order in which they'll be returned? (Eg perhaps in the order each
row is added to the collection...)
I ask because I've been using a particular collection for ages, but forgot to specify
an order when querying from it. Just today it returned the rows in a different order
than it has in the past -- only once -- and then they were returned as before.
The order I want -- and have been getting -- is the order in which they're added to the collection.
Will the 'no query transformation' hint accomplish this, or do I need a member that specifies the order?
Thanks,
C

Never mind... got it.

T3Client connection to cluster from appserver ends up *always* in the same appserver!!!! Why???

I found that T3Client connection to cluster from appserver ends up always
          in the same appserver!!!!
          Why??? I fail to understand why it wouldn't follow the standard round-robin
          procedure???
          -- Angsuman


I guess the RMI object you connect to is using "sticky to first server".
          This is default. For your own RMI object, there is a way to turn the
          "sticky" off, refer to cluster and RMI object documents for details.
          For EJB objects, refer to "Urgent: Please help!" message for details.
          Cheers - Wei

Error: The report source could not be retrieved from the state object.

I have been trying to create a report in a JSF page. The relevant parts are below:
Inside the JSP page, this is the code:
              <jsp:useBean id="MyBean" class="com.nm.facade.rto.POJOViewerBean" scope="session" />
                <jsp:setProperty name="MyBean" property="reportLocation" value="Report1.rpt" />
               <v:reportPageViewer reportSource="#{MyBean.reportSource}"
                                       displayToolbarPrintButton="true"
                                       printMode="ActiveX"
                                       zoomPercentage="100"
                                       displayToolbarExportButton="true"
                                       displayToolbarRefreshButton="true"
                                       viewerName="My Viewer"
               ></v:reportPageViewer>
In the backing bean, this is the relevant code:
    public Object getReportSource() throws ReportSDKException
        if (propertiesChanged || reportSource == null)
            propertiesChanged = false;
            if (reportLocation == null)
                throw new RuntimeException("The reportLocation property must be set before a report source is retrieved");
            ReportClientDocument rcd = new ReportClientDocument();
            rcd.setReportAppServer(ReportClientDocument.inprocConnectionString);
            rcd.open(reportLocation, 0);
            DatabaseController dbc = rcd.getDatabaseController();
            //Create the POJO collection and populate it with data
            ReportData[] data =
              new ReportData("B.B.", "King", 6, new Date(25, 9, 16)),
                new ReportData("Muddy", "Waters", 7, new Date(15, 4, 4)),
                new ReportData("John Lee", "Hooker", 8, new Date(16, 8, 16)),
                new ReportData("Otis", "Rush", 9, new Date(34, 4, 29)),
                new ReportData("Buddy", "Guy", 10, new Date(36, 7, 30))
            //Create the result set from the collection of POJOs
            POJOResultSetFactory factory = new POJOResultSetFactory(ReportData.class);
            factory.setVerbose(true);
            POJOResultSet results = factory.createResultSet(data);
            ResultSetMetaData metaData = results.getMetaData();
            //Set the resultset as the report datasource
                  //Get the table name from the 'Set Datasource Location' dialog in the Crystal Reports designer
            String reportTable = "getReportDataDataSource";
            dbc.setDataSource(results, reportTable, reportTable);
            IReportSource reportSource = rcd.getReportSource();
            if (reportSource == null)
                throw new RuntimeException("Unable to get a report source.");
        return reportSource;
In the CRConfig.xml, this is what is there:
<?xml version="1.0" encoding="utf-8"?>
<CrystalReportEngine-configuration>
    <reportlocation>../reports</reportlocation>
    <timeout>0</timeout>
    <ExternalFunctionLibraryClassNames>
         <classname></classname>
    </ExternalFunctionLibraryClassNames>
</CrystalReportEngine-configuration>
The report template 'Report1.rpt' is packaged under WEB-INF/reports in the war file.
When I try to generate the report by accessing the JSF page, I am getting an error: "The report source could not be retrieved from the state object. "
I am not sure what is wrong. Can someone help me in resolving this issue?

Call stateless session bean EJB 2.0 from Webdynpro Java UI

Hello,
Can someone please tell me asto how to call a stateless session bean EJB 2.0 from Webdynpro Java UI?
The NWDS version is 7.0.
Thanks and Regards,
Arya

Hi Aryadipta
Please check this pdfs
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10&overridelayout=true
Steps for calling stateless session bean in Webdynpro java
Go to NWDS -> open perspective ->j2ee
select EJB Module Project ->create a project with name
Open the Project -->RC on ejb-jar.xml -> Select new --> EJB
Give name to EJB Bean (First letter should be in capital letters)
select the type of bean as Stateless session bean and give the package name to store that EJB bean.
After that Expand ejb-jar.xml and then select the <projectEJB>
Double click on this on method tab double click you will get business method where we will create the methods for business logic
Double click on projectEJB and then RC on bean tab and write required business logic in bean window as follows(based on requirement we will design a business logic).
After writing the business logic go to project -> rebuild
Till now we have created one EJB jar file
then go to File-->Enterprise Application Project -->create a project (projectEAR)
After creating a project click on next-> here we will have ear projects and then we select specific project required for our application.(here select projectEJB)
After that Calculate EAR project will be available on j2ee explorer.
Right click on <Bean> here
select New->Web Service->give a name to webservice and select Default configuration type as simple SOAP
-->click next -> Finish.
That webservice and related are created in ejb-jar.xml .
Expand the ejb-jar.xml.and double click on < webservice>
RC ProjectEJB -> Build EJB Archive RC on CalculateEAR ->Build applicationarchive.
Expand the projectEAR->RC on CalculateEAR.ear->Deploy to J2EE Engine
Double click on calculateEAR.ear ->Webservice navigator tab ->we eill servers expand the node
select the specific WebService
Here we test the webservice by click on Test and test it.
After that go to Web dynpro perspective ->create one webdynpro Project and one component
RC on model> Select import Web Service model(last)>give model name and package
and select radio button as local file system or URL
Go to WSnavigator->copy the WSDL path and paste it in model WSDL path and click on finish.
from here onwards steps are same as that adaptive RFC model
Hope it helps
Thanks

DirectAccess Server 2012 Configuration cannot be retrieved from domain controller

Hi everyone,
We are using DirectAccess over Server 2012. There is just one server, no load balancing.
Everything works fine, all clients can connect successfully and operations status page shows all in green. Nevertheless on the dashboard page in the configuration status section it say “Configuration for server [servername] cannot be retrieved
from the domain controller.”
I found a few hints what could cause this problem:
In my case, the RAConfigTask, a scheduled task, was not enabled on the affected WS2012 server (DA entry point in a multisite deployment). After just enabling it, the errors has gone."
http://blog.gocloud-security.ch/2013/01/11/ws2012-directaccess-and-the-configuration-for-server-server-name-retrieved-from-the-domain-controller-cannot-be-applied-error/
Group Policy was filtering out my DA server from the GPO object for some reason. To fix, I opened up Group Policy Management on the domain controller and made sure that my DA server was a part of the group."http://www.joedissmeyer.com/2012/12/more-issues-and-solutions-for.html
Server has no connectivity to the domain in order to update the policies. Run “gpupdate /force” on the server to force policy update. GPO replication might be required in order to retrieve the updated configuration.
This could be because there is no writable domain controller in the Active Directory site of the Remote Access server. http://social.technet.microsoft.com/Forums/en-US/winserverNIS/thread/56fedb17-1274-4e1a-b2d0-fea809f0bc45
I checked everything. Task is enabled and completed successfully, GPO is not filtered out, run gpupdate without any errors, could connect to domain controller, no errors on domain controller, domain controller is writable.
So, I have no idea what could cause this error. Any ideas or hints?
Thanks
Regards
Sebastian

i have the exact same problem i figured out that there was a problem with the logon as a service
secpol.msc --> Local Policies --> User Rights Assignement, Logon as a service i have NT Service\All Services
i can acces the group policy via the cpnsole just fine i have not connectivity issues what so ever.
i decided to open a call with microsoft, their suggestion .... we dont know reinstall so i did and here we are same problem and no solution. it is getting frustrating...

Count rows in a table being retrieved from dba_segments

Hello guys,
I was wondering how can I count the rows in a table that is being retrieved from dba_segments.
-- I am getting the table name from dba_segment
-- Is it possible to count the number of rows in that table at the same time?
-- If not, is there an alternative step without analyzing the table or schema, then getting the result from num_rows in all_tables?
I want the count code to add to the select statement..
SELECT owner, segment_name , segment_type, partition_name, bytes
FROM   dba_segments
WHERE owner = UPPER( v_schema )
ORDER BY segment_name;I try to add this to the select statement. count(segment_name), but that did not work.
Any direction(s)?

Can I use stored procedures to improve data retrieval from the database?

I have been requested to get multiple pieces of data from multiple tables and return the output in an array for use in a Java program.
Eliminating multiple calls to the database. Currently, the data is retrieved from the database in multiple steps but to eliminate
possible bottlenecks in the future, I created several complex sql statements.
For instance,
In the first table there are 20 columns of data. has a column named type which can have the one of these values: line, inn, or bsc
In the second table there are 6 columns of data. has the additional data for type line
In the third table there are 7 columns of data. has the additional data for type inn
In the fourth table there are 2 columns of data. has data regardless of type
etc...
Depending on a specific column value retrieved (inn) from the first table:
I need to collect all 20 columns in the first table and get all the columns in third table and the columns in the fourth table, etc.
Question: How can I remove the duplicate primary key columns without specifying for each table the column names to be returned?
I used the wildcard SELECT * because I didn't want to have to update the retrieval methods if additional columns are added to these
secondary tables.
example of my sql for type inn data:
select * from first_table f, third_table s, fourth_table t
where (f.column1='xxxx' and f.column2='xxxx') (the 'xxxx' are passed into the sql statement)
and
((s.column1=f.column1 and s.column2=f.column2)
and
(f.column3=t.column1));
Currently, I've duplicated the separate sqls for each valid type found in the first table (at least a dozen types). The only difference is
the table name. Instead of the third table I use the second table, etc.
The MAIN Question: How can I set this up to have one sql to handle each type? I want to eliminate having over a dozen duplicated sqls. Can I
incorporate this into a stored procedure or something? If so, how? Can anyone provide sample coding?
Your help is very much appreciated. Thank you.

Hi, Salah.
Use "Exec" in your query to run procedures.
SAPbobsCOM.Recordset oRS;
oRS = (SAPbobsCOM.Recordset)pCmp.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRS.DoQuery ("EXEC YourStoredProcName");

Data Retrieval from SSRS 2008 R2 to SQL Server 2012 standard

Hello,
We have a virtual machine running SSRS 2008 R2 and a physical server running SQL server 2012 standard. We are having an issue with a report that is taking almost 10 minutes for the data to be retrieved from the sql 2012 database. We used the
execution logging query to debug and analyze. We see that it renders and processes very fast, but the data retrieval time is very slow. When the same query is run using sql studio mgr. from the SSRS server it runs just fine...it
takes seconds for the results to come up.
I don't believe there is a compatibilty issue because other reports run fine. We're just having problems with one report.

A long shot, but I've seen where the data type of a report parameter is mismatched against the data type of the table it is being compared against. SQL profiler would show this clearly.
This would explain why the query returns quickly in ssms but not with the report.

Workflow task details are being retrieved from the server

Hi,
Using an approval workflow. when the task has been assigned to the person he is getting an email but when clicking on the edit this task button ,the pop window with the
"workflow task details are being retrieved from the server"
error is getting. SharePoint site 2007 and Microsoft Outlook is 2010.

I have a similar issue with my version of SharePoint.
SharePoint 2010 Enterprise.
Outlook 2013 with MS Exchange
Document approval workflow.
When you open the document approval email that comes from SharePoint and click on "Open this task" the popup window flashes across "workflow tasks details are being retrieved from the server ".
I've tried the regedit fix and the hive fix and resetting IE that some of the other people have said that works and it doesn't.
When I go the site, and connect the task list to Outlook, I can complete the task that way.
I also created a new approval workflow in SharePoint designer and it behaves the same way.
Anything else I should try?

Data Could not be retrieved from database...

Hi All,
I have a problem on Excel 2007 while refreshing (for pivot table) data from SQL Server view:
"Data could not be retrieved from database. Check the database server or contact your database administrator. Make sure that external database is availiable, and then try the operation again"
Excel file is distributed on about 20 workstations in network with the same Excel version, and problem occurs only on one station. I have checked credentials and connection between workstation and server and it seems to be ok.
Any ideas?

it is problem, because sql server is not member of domain... so I'm using sql aunthentication.
strange thing is that from any other workstations (aldo in domain) it works fine when providing SQL user. I'm supposing that it is problem with some excel settings

How do you retrieve a Collection of objects using JDBC?

How do you retrieve a Collection of objects using JDBC.
MORE INFO:
I have created a class i.e. Account class and I want to retrieve all the accounts previously created for accounts in my Mysql database..
my method would retrieve an array of Account instances in the database i.e.
public Vector retrieveAccounts();

Connection con = null;
ArrayList accounts = new ArrayList();
try{
con = DriverManager.getConnection(...);
PreparedStatement ps = con.prepareStatement("select * from accounts");
Resultset rs = ps.executeQuery();
while (rs.next()) {
    Account account = new Account(rs.getString(1), rs.getString(2), ...);
    accounts.add(account);
Account[] account_array = new Account[accounts.size()];
accounts.toArray(account_array);
catch (SQLException sqle) {
   sqle.printStackTrace();
finally {
if (con != null) {
    con.close();
}should pretty much to what you want, you will obviously need to change it so that, a) the SQL query is correct and b) the Account class is correct and c) the correct values are taken from the result set to create an account.

Problems with Apple Mail retrieval from EarthLink

I just bought a new computer (MacBook Pro 10.8.2 Mountain Lion) and when trying to set up Apple Mail v.6.2 I have a problem. It won't connect properly with my ISP email (EarthLink). I am unable to retrieve any POP mail on Apple Mail. It keeps saying "Logging in to the Earthlink POP server "pop.earthlink.net" failed. Make sure the user name and password you entered are correct....." However, I am able to send mail via Apple Mail because the outgoing mail server (smtpauth.earthlink.net) does work. It's strange because it's the same user and password. So I can send but not retrieve using Apple Mail.
I also have Thunderbird, which I don't really like, and its POP setup both sends and retrieves from EarthLink without a problem. Plus I can always go to the EarthLink website if necessary. So this is not critical, but I prefer Apple Mail.
Any ideas?
(I'm also going to contact EarthLink to see if they can help.)

I'm having this difficulty with my shared host provider as well. hostpapa.ca keeps telling me to 'check my account settings.' This is not difficult to do and the error code I keep getting tells me that there's a problem connecting to the mail server.
While I argue with them, is it possible that there is a problem from within Apple Mail or with my wifi? Mail works well when I'm not on my home network - at the office, on 3G, if I use webmail, if I connect directly to my DSL modem. I tried to delete the account and add it in again - but it just won't connect when on wifi.
I'm wondering if there's anyone who has an answer to this...?

EJB not found from client Servlet

Hi:
Using Netbeans 6.0 and Glassfish
I have deployed a stateles session EJB.
From a servlet in a different application I call the EJB with the following annotation:
@EJB
private LogFacadeLocal logFacade;
When I deploy this servlet I get the following error:
Deploying application in domain failed;
Error loading deployment descriptors for module [WebDBT] --
Cannot resolve reference Unresolved Ejb-Ref WebrDBT/LogFacade@jndi: @[email protected]@Session@null
What is missing? How can I define the EJB so the servlet will find it with the above anotation?
Thanks

what you're missing is the comprehension that an EJB local interface will work only from within the same enterprise application (so the same ear file or EJB jar).
