Types of bad operand for the binary operator '! =' error

Hello

I get the following compilation error:

types of bad operand for the binary operator '! =';  Firstly, type: oracle.jbo.domain.Date;  Second: null type >

When I try to compare a Date with null object, for example:

    public static Calendar jboDateToCalendar(Date d) {
        if (d != null && d.getValue() != null) {
            Calendar c = Calendar.getInstance();
            c.setTime(d.getValue());
            return c;
        }
        return null;
    }

I use JDev 12.1.3. running with Java 1.7.0_75.

Does anyone have an idea? Ever seen this error before.

Media do not help btw.

Thank you

Johannes

I found the solution. I used only the 'Oracle BC4J areas' library to import the Houston to date data types.

After adding "Oracle JDBC" such as the library, the errors disappeared.

  • Storage VMotion - a general error occurred: could not wait for the data.  Error bad0007.

    People,

    I searched through this forum and have not found an answer that works in many positions out there, I say to myself that I would ask him once again.

    Here's the context:

    We have 12 identical Dell M600 blades in 2 chassis with 16 GB of Ram, 2 x Xeon E5430, they are all connected to an Equallogic PS 5000XV iSCSI SAN on a separate iSCSI (vswitch1) with 2 cards network dedicated network and dedicated switch, console svc iscsi dedicated, dedicated VMkernel port for iscsi access. Net access (vswitch0) contains port groups VM for our various networks and a console port and vmkernel svc for VMotion with 2 separate NETWORK cards as well.

    We are running ESX 3.5 U3 and VCenter 2.5 U3 on Win2k3 R2

    VMotion works between all servers, Storage Vmotion works for most machines, HA works and the value 2 host failurs with no monitoring of vm, DRS is set to manual for now I have a few machines on the local stores that I complete my rebuilt LUN, there is no set of rules for DRS and VMware EVC is enabled for guests of the Intel. However, I'll just describe one machine to do svmotion below.

    Here's the problem:

    I'm trying to Svmotion via svmotion.pl - interactive, a Machine to Windows 2000 with a virtual disk and a virtual RDM. I am aware of the requirements for the RDM and required parameters for svmotion, independent is not selected for the RDM, and I also have svmotioned several machines linux and win2k3 with the same configuration without problem. In the interactive session, I choose to individually place the disks and I chose the virtual disk to only the virtual machine to be moved, essentially, as I saw it move vdisk virtual machine and then copy to the pointer of the RDM.

    The use of the processor in this machine is about 25% average. but I try to run migrations at the time the lowest. and The Host it itself shows only about 5.5 GB of the 16 GB of RAM used. so I think we're good on the RAM. the volume/datastore that I'm migrating from has 485 GB free and the volume/datastore I migration towards a 145 GB free. the VM virtual disk is only about 33 GB.

    I run the script the windows version of the RCLI svmotion. and when to begin the process, I get the following error at around 2 percent of the progress:

    "Since the server has encountered an error: a general error occurred: could not wait for the data."  Error bad0007. Invalid parameter. »

    After searching around, I found the following hotfixes to the U2 release notes

    • Migrate.PageInTimeoutResetOnProgress: Set the value to 1.

    • Migrate.PageInProgress: The value 30, if you get an error even after the setting of the Migrate.PageInTimeoutResetOnProgress variable.

    I've made these changes, and I still get the same error.

    When I dig in the newspaper, I see these entries in the journal of vmkwarning:

    The vmkernel on out of memory error, I had that before. And vmware support recommends setting 800M Max service console memory. And I did it and have no problems after that.

    See if that helps the issue.

  • Is it possible to use a Type of personalized content for the REST service operation messages?

    I try to POST to the third party, documentum of EMC, REST service using service broker in 8.53 peopletools integration operations. Unfortunately, the third party only accepts a content type of 'application/vnd.emc.documentum+json', which I could not send PeopleSoft and use a message definition at the same time.

    In my service operation, if I do NOT fill the request message I can POST to the URI with the such custom content type defined in the property page of the connector in the routing. I have not found a way to do it and also present JSON content on demand, since there is no message associated with the operation. Is it possible to include in this type of message content without using a request message?

    If I DO not fill the request message I can't POST successfully because the message content-type of "application/json" gets passed as the content-type instead of the value in the property page of the connector from the routing. Is it possible to change the content type during the use of a message definition?

    Thank you

    Paul

    Hi Paul - you can turn on tracing by using the on demand connection as follows:

    1. on the routing set detail header and detail "journal".

    2. Main Menu > PeopleTools > Integration Broker > Service Operations Monitor > Administration > control installation Options

    -Enable logging of the bridge

    -On the registration of demand = 5 (to enable detailed logging)

    Note: On request connection only works for the outgoing synchronous Services. In this case, we should be fine. You will find the by transaction log file on your gateway web server... / applications/peoplesoft/PSIGW.war/WEB-INF/.

    I did it for one of the REST service operations my test (I'm on 8.52.22). I have my content type of message the value application/json to the operation of the service page. On the routing page, I added a connector property content-type=application/vnd.emc.documentum+json.

    Here are the results on the integration gateway logs:

    The Content-Type of the delivery is sent as HTTP Connector of the target and the content of the message (text/json) Type property is always persistent (see the text in bold above). You can compare logs between your two scenarios (with and without the message in the POST) and see if you find something interesting.

    I even tried the following code to see if that helps, but I get the same results.

    & MSG. IBInfo.LoadRESTHeaders ();

    / * Adds additional headers not defined on the route * /.

    REM & MSG. IBInfo.ConnectorOverride = True;

    bRet = & MSG. IBInfo.IBConnectorInfo.AddConnectorProperties ("Content-Type", "application/vnd.emc.documentum+json", % Httpentete);

    & RESP = IntBroker.SyncRequest % (&MSG);)

    I'm working on a similar project at this moment where I'm integrating perceptual Nolij Web RESTful API (Document Management System). I had to resort to using a http client base (common of apache) java instead of broker of integration because of the similar frustrations with REST (cookies are lost, unable to deal with raw binary data in a response message, etc.).

    Benefits: Java provides total flexibility.

    Cons: As we are bypassing framework Integration Broker, we need everything (error handlng, logging, etc.) do it ourselves.

  • Precedence of operators for the increment operator

    Hi guys,.

    When I try an example for working with the increment operator (pre increment or post-increment operator), I studied in a book that the associativity of the increment operator will be from right to left. And I tried an example to confirm, but apparently works left to right associativity.

    Here's my example
    public class RightToLeft 
    {
         public static void main(String[] args) 
         {
              int i = 5;
              int j = ++i * i++;
              System.out.println(" i value :"+i);
              System.out.println(" j value :"+j);
         }
    }
    
    Ouput : i value : 7
                j value : 36 
    Here, if java works with right of associativity of left in handling operator increment the value of j would be 35, but it gives 36 by evaluating the expression from left to right.

    Can you please let me know if I believe in a bad way.

    Thank you
    Uday

    Increment operators are monadic and monadic operators bind more closely than any diadic. The associative property does not apply to monadic operators.

    So you get the equivalent of (++ i) * (i ++). Associativity is related to the * operator, but it only applies if you have more than one driver of diadic of the same priority.

    Associativity determines the order in which, for example 'i + j + k' is evaluated. It's like (i + j) + k or i + (j + k). (Either way it is always evaluated left to right).
