Created with second class object failure.

Hi All,
When I am trying to import tables from the database, I got the following warning message.
Only for some of the tables I am getting.
The table is importing properly. But I don't know why I am getting this error.
Please anyone can explain.
Thank you,
Regards,
Gowtham Sen.

Hello!
Second class objects are columns, indexes, constraints etc. Probably some of these contains reserved OWB keywords. You can check what went wrong by drilling down to these objects on the results screen.

SECOND CLASS OBJECT FAILURE

When I try to import a table into my target warehouse I get a message saying 'created with second class object failure'.
What is this referring to ??
Thanks in advance
Paul Heath

Paul,
It is possible that a second class object (a table field, for example) is not created correctly. OWB does not support certain data types, so I suggest to check you table structure.

MakePersistent exception and second class object value

1. When makePersistent is called on an object with application id that
already exists in the database, a JDOFatalDataStoreException is thrown.
The JDO specification calls for a JDOUserException (17.1.4).
2. If there are stray data for a second class field (e.g. Hashtable)
before the object is created, the stray data will become part of the value
of the second class object.
Suggestion: Delete statements should be issued to delete stray values for
second class fields.

Well, you can always do this type of cleanup manually if you so desire.
Having Kodo automatically guess about what constitutes valid data seems
pretty dangerous though.
I'd suggest that you put the appropriate deferred referential integrity
checks on your schema instead. This will let the database guarantee the
consistency of the data.

Help With Multiple Class Objects With Methods

I am dealing with multiple classes. I am wondering why I am getting an error on this line it's by the bottom
          obj1.array() = newArray[i];
It gives the array out of bounds. On another note I believe I can change obj1 to just like incomingArray if I wanted correct since it's just a reference because I should be able to do this method sort on any array.
method : selSort
input - none
output - void
This is where we sort the arary
Pseudocode Code:
1 Initialize variable oldlocation to hold spot of smallest number in original array
2 Initialize variable smallnumber to store smallest number in original array
3 Initialize new integer array
4 Set new array length to length of original array
5 Initialize variable length to store lengh of new array
6 For i = 0 and continue till i < new array length
6.1 Find smallest number in original array
6.2 Put the smallest number in new array
6.3 Remove smallest number from original array
7 Copy contents of new array that is sorted to original array
Basic concept is to repetitively find the smallest
(or largest) item in the original array. Once smallest
is found, move it to the next spot in a new array and
remove it from the old array.

Problems with String[] Class Object

Hi guys,
I'm writing a web server who should invoke a method of a class when asked by a client.
My problem is that if the method that should be invoked has a String[] parameter the web server is unable to invoke it and throws a java.lang.IllegalArgumentException: argument type mismatch.
Useful pieces of code to understand are the following:
//create the Class[] to pass as parameter to the getMethod method
Class[] paramType = {String[].class};
//find the class "className" and create a new instance
Class c = Class.forName(className);
Object obj = c.newInstance();
//the getMethod should find in the class c the method called nameMeth
// having paramType (i.e. String[]) as parameter type...
Method theMethod = c.getMethod(nameMeth, paramType);
//here's the problematic call!!
theMethod.invoke(obj, params);I've noted that System.out.println(theMethod); prints the signature of the method with the parameter type java.lang.String[].
System.out.println(paramType[0]); instead prints [Ljava.lang.String;
I know that [L means that it is an array, so why do you think that I'm having an argument type mismatch?
Thank you

I had no problems making that work.import java.lang.reflect.Method;
public final class StringArray {
    public static final String CLASSNAME = "StringArray";
    public static final String METHODNAME = "myMethod";
    public static final String[] sa = { "a", "b"};
    // automatic no-args constructor
    public final void myMethod(String[] sa) {
        for(int i=0;i<sa.length;++i) {
            System.out.println(sa);
public static final void main(String[] arg) throws Exception {
//create the Class[] to pass as parameter to the getMethod method
Object[] params = { sa };
Class[] paramType = {sa.getClass()};
//find the class "className" and create a new instance
Class c = Class.forName(CLASSNAME);
Object obj = c.newInstance();
//the getMethod should find in the class c the method called nameMeth
// having paramType (i.e. String[]) as parameter type...
Method theMethod = c.getMethod(METHODNAME, paramType);
//here's the problematic call!!
theMethod.invoke(obj, params);

Creating New Class Object progmatically

Instead of uploading an XML for a new type definition, I want to create a new class object progmatically.
In my code, I basically set up a ClassObjectDefinition, set the attributes, then call createSchemaObject.
I'm getting an exception saying that I have an invalid or missing option.
What is the bare minimum needed to create a new Class Object?
null

First - you must be admin mode to create any subclasses. Minimally, you need to set:
- ClassName
- SuperClass
- your custom attributes
If you have created your own java class which is optional, you will need to set:
- BeanClassPath
Then there's optional settings such as Description.
If this doesn't help, is it possible to post your code setting the ClassObject Definition attribute Values (AVs) and the create?
As a guide, you should set all the AVs that you used to create a subclass via XML.
Another note - once you create subclass named FOO, you will not be able to create another subclass named FOO.
Another note (!): by default, iFS will use your class name to create the DBMS table. If you have a particularly long class name which will exceed the DBMS limits for table names, then you will want to set:
- DatabaseObjectName
hope this helps.

New class object statically.

I have a class Test. This class has a static method which has as its purpose to create a new Test object. I currently have something like this:
public static Test getInstance() {
return new Test();
}I was wondering if it is possible to write this code in such a way that no explicit reference to Test was made... and, as the always important follow up question, if it is possible, whether it is wise to do so?

I have an interface and several classes implementing
that interface. Each of these classes has a static
method that has a Hashtable as a parameter. When that
static method is called, the method creates an object
of the class it is in and then adds the object to the
Hashtable (the key for this entry is retrieved from
the class its from).
The 'problem' is that I have to write each of those
methods in each class myself, when all I really want
is to do the exact same thing over and over again
(with each of the classes), just with different class
objects.it's not "the same exact thing" over and over, though, is it? you're instantiating different classes in different methods. are you doing this to keep track of instances? you could have a factory that uses reflection to instantiate classes, and add them to the correct Map, but it can be awkward

Class object saving performce issue - (Workflow activity)

Hi,
I created a custom activity with a class object. If I call WorkflowDesigner.Save(filename) method, it takes a lot of time for saving class object.
public class Abc: AsyncCodeActivity
        public Class1 Class1Obj
            get
                return class1Obj;
            set
                class1Obj= value;

Hi,
where are your external services located   If they are in the same assembly as the workflow (and this goes for custom activities as well), you can have all sorts of problems because you (well, VS) are constantly reloading assemblies and they can
get out of synch.

I have tried incluijng those class files for the custom classes within the jar file, but I continue to get the same issue?
Any help would be gratefully received.
Thanks

This error is no longer coming up, it is now saying that it has an unsupported class version error. I believe this may be because the class file and library files have been complied under different versions, is there a method to check this?

Hello
I assume you want to create multiple instance of your class.
Assuming that you class is NOT a singleton then simply repeat the CREATE OBJECT statement as many times as you need.
TYPES: begin of ty_s_class.
TYPES: instance   TYPE REF TO zcl_myclass.
TYPES: end of ty_s_class.
DATA:
lt_itab      TYPE STANDARD TABLE OF ty_s_class
                 WITH DEFAULT KEY,
ls_record TYPE ty_s_class.
DO 10 TIMES.
    CLEAR: ls_record-instance.
    CREATE OBJECT ls_record-instance.
    APPEND ls_record TO lt_itab.
ENDDO.

Problem with Dynamically accessing EJB Class objects in WL 7.0 SP1

I am trying to build a component which has the ability to instantiate and execute
an known EJB method on the fly.
I have managed to build the component but when I try and execute it I get a ClassNotFoundException.
I know that the EJB I am trying to invoke is deployed and available on the server,
as I can see it in the console, I also seen to have been able to get the remote
interface of the object, my problem occurs when I try and access the class object
so I can perform a create on the object and then execute my method
The code I have written is below:
private Object getRemoteObject(Context pCtx, String pJNDIName, String pHomeBean)
throws Exception {
     String homeCreate = "create";
     Class []homeCreateParam = { };
     Object []homeCreateParamValues = {};
try {
//This call seems to work and doesn't throw an exception
Object home = pCtx.lookup(pJNDIName);
//However this call throws a java.lang.ClassNotFoundException
Class homeBean = Class.forName(pHomeBean);
Method homeCreateMethod = homeBean.getMethod(homeCreate,homeCreateParam);
return homeCreateMethod.invoke(home, homeCreateParamValues);
} catch (NamingException ne) {
logStandardErrorMessage("The client was unable to lookup the EJBHome.
Please make sure ");
logStandardErrorMessage("that you have deployed the ejb with the JNDI
name "+pJNDIName+" on the WebLogic server ");
throw ne;
} catch (Exception e) {
logStandardErrorMessage(e.toString());
throw e;
Any advice would be really appreciated, I'm fast running out of ideas, I suspect
it has something to do with the class loader but I'm not sure how to resolve it
Regards

Hello Joanne,
Congratulations! I'm very happy that you've managed to fix your problem. It's
always essential to understand how to package applications when deploying on BEA
WebLogic. Usually, by throwing everything into an EAR file solves just about all
the class loader problems. :-) Let us know if you have any further problems that
we can assist you with.

Hello Joanne,
As Mr. Woollen mentioned, I also believe it's a problem with the class
loader.
You need to be careful how you arrange your EJBs, because WebLogic has
a specific
method in which it loads classes in an EAR, JAR, and WAR file(s). Please
refer
to http://dev2dev.bea.com/articles/musser.jsp for more information about
BEA WebLogic
class loading mechanisms and caveats. Also, try printing out the various
methods
that are available on the object that was returned to you via reflection.
For
example, use the getMethods() method, which returns an array of Method
objects
that you can subsequently cycle through and print out the various method
names.
This way you can discover if the class found/returned to you is indeed
the one
you intend to locate.
Hope this helps,

I believe the issue is the home interface class for this EJB is not

If you do:

Hi Ryan,
I also wanted to mention that if you do a "header search" in this

Are the EJBs that you are trying to access accessible via your
system
classpath?
Try to avoid having them accessible via the main system classpath,and
only bundle
them in your appropriate EJB jar files (contained in an EAR file,for
example).Maybe I should have laid the problem out a little clearer.
I have a number of EJB's bundled up in a JAR file which is hot deployedto
the
server. Within this first JAR file is an EJB (SSB) component that
needs
to
be
able to invoke a known method on another EJB. This second EJB may
or
may
not be
within the first JAR file but it also will be hot deployed.
The component trying to invoke the method on the 2nd EJB has to
be
able to
create
an instance of the 2nd EJB without actually knowing anything bar
a
JNDI
Name which
is passed in at runtime.
I can get as far as doing the
Object home = pCtx.lookup(pJNDIName);
This returned a class with the name
"com.csc.edc.projects.allders.httppostoffice.postman.PostmanBean_mp8qy2_Home
Impl_WLStub"
My problem seems to occur when I try and invoke the create method
Method homeCreate = home.getClass().getMethod("create", new Class[0]);
My code throws a java.lang.NoSuchMethodException at this point so
I
am
unable
to progress to the next step of :
Object bean = homeCreate.invoke(home, null);
So I can return the instantiated bean back to the calling client.
Why am I getting the NoSuchMethodException, is is because I am gettinga
stub
back rather than the home interface and if so how do I get the truehome
interface
from the bean
Thanks in advance

ABAP Objects with Workflows / Classes and Instances

Hello,
I am currently designing a workflow using an ABAP-Objects. So far I have been been able to get my Workflow to run with my class, but I have a couple of problems:
- I am using the Function 'SAP_WAPI_START_WORKFLOW' to start other subflows, which enables me to decide which subflow to start at runtime. All of the subflows have standart importing-parameters in their containers, such as the key of my class. In each workflow I instantiate my class using a self-written method, which checks the table T_INSTANCES in my object, and then either returns the object reference to an existing instance or creates a new one. Obviously all of the subflows that I call from my main workflow should be able to find the instance. As far as I can see in their protocolls, this happens without any problems. The problem starts when I make changes to the instance. For example the changing of attributes (with setter methods) seems not to work. After the subflows are finished, in my main workflow, I do not see (with getter methods) any changes that has been made to the object. Is local persistence really limited to one workflow ?
- My second problem is basically about the workflow container in workflow protocoll. In the same workflow, I can change the attributes of my object. Nevertheless, the protocoll always show the initial attribute, even though, my task with the getter-method returns the new value of the attribute.
I appreciate any help and thanks a lot in advance.

Hello Pauls,
Thank you for your answer. I think we are misunderstanding each other. The problem occurs (I think) because my class is not a singleton class. Or am I mistaken ?
When I directly start a subflow from my main workflow, then the instance that I have created in my main workflow is also visible to the subflow. As well as the static table which actually keeps track of the instances. So, in this case the subflows finds the instance and then can use the object as is.
When I start a subflow from my main workflow using the function I mentioned above, then even though the same object key is used, there is a new instance. And the static table (I assume that you mean a static variable from type table, when you say "class table") is completely empty. In this case, my "new" instance is created which overwrites every attribute that I have set in the main workflow, before I started the subflow. More interestingly, my main workflow instantiates another new object, as soon as the subflow has finished. (I am using an event to wait for the subflow to finish.)
On the other hand, I am not quite sure that I understood your approach with refresh and how it could help me. This method is not well documented anywhere, and all of the examples that I have found are about "leave it empty"
As far as I understood, this method is called by the workflow between the steps, when an object is used. I slowly start to think that I need advanced information about Workflows and Memory Management.
Thanks a lot again. Apparently, I am the only person who came across such a problem
