Generic attributes with NavigationMenuItem class

hi,
Im building a dynamic navigation using a List<NavigationMenuItem>.
The menu is generated from a database.
I add a ActioListener to the NavigationMenuItem which resolves its value, depending on it the next page is displayed.
But id rather save the primary keys corresponding to the values into the NavigationMenuItems.
Is there a way i can add generic attributes dynamically to a NavigationMenuItem object?
Or do i have to extend NavigationMenuItem and a new property (i that possible at all?)
besides id like some general iformation about generic attributes, i cant find much.
thx in advance!

no pointers? :(

Binding ABAP Class Attribute with BUS2038 in a Standard WF task

Hi,
I need help as mentioned in the subject line.
In my standard task I am capturing event for BUS2038. In the General tab I have a ABAP class which has implemented IF_WORKFLOW. From BUS2038 I just need notification number.
Since my source is a BO and my target is a class. How do I make this conversion and pass the data to my class?
I know there are several solution but none have solved my concern.
Thanks,
Sridhar Karra.

Hi,
If you want to access teh attributes of the BOR inside a class emthod then you have to make use of teh MACROS.
1. include INCLUDE CNTN01_SWC in the class local macros section. and in the type groupsof the class include SWC0.
2. Now if you know the key of the BOR instance then create a BOR object inside the class method as below
DATA lo_object TYPE SWC0_OBJECT.
SWC0_CREATE_OBJECT lo_object '<BUSXXXX>' '<Key of the BOR>.
the above line will create the instance of the bor inside the class method
now inorder to access the attributes of the BOR use the below code
DATA lv_notif_no TYPE <type of the notification>.
SWC0_GET_PROPERTY lo_object '<ATTRIBUTE NAME> lv_notif
In this way you can access the BOR attributes inside a class method.

Generic Attribute in MXBean

Hi,
I'm trying to register an MXBean (using Java 1.6) that has a get attribute that returns a generic class with the type specified in the interface. I get a non-compliant mbean exception thrown indicating that the method in question returns a type that cannot be translated into an open type.
Here is some code that illustrates what I am trying to do:
    public static class GenericValue<E>
        private final E val;
        GenericValue(E val) {
            this.val = val;
        public E getVal() {
            return val;
    public interface GenericHolderMXBean {
        public GenericValue<Float> getVal();
    public static class GenericHolder
            implements GenericHolderMXBean {
        @Override
        public GenericValue<Float> getVal() {
            return new GenericValue<Float>(1.0f);
    TestMbeanStuff.GenericHolder genericHolder = new GenericHolder();
    MBeanServer m = ManagementFactory.getPlatformMBeanServer();
    ObjectName name = new ObjectName("com.test:type=GenericHolder");
    m.registerMBean( genericHolder, name )Is there a way to make this work? It seems analogous to List working as an attribute in an MXBean, but perhaps support for collections is a special case made by JMX and it is not possible to use one's own generic types?
Thanks,
Ryan

Thanks for your response Éamonn,
I do have a bit of a follow-up question. My original question was a simplification of what I would like to do. What I'm really after is having my MXBean interface return a type that has a generic type nested as an attribute. eg:
    public static class GenericHolder {
        public GenericValue<Float> getVal() {
            return new GenericValue<Float>(1.0f);
    public interface NestedGenericHolderMXBean {
        public GenericHolder getVal();
    public static class NestedGenericHolder
            implements NestedGenericHolderMXBean {
        public GenericHolder getVal() {
            return new GenericHolder();
    }I would still like to make this work and can see a way to make it work. But, there are a couple of ugly things about my solution. I can probably live with them, but would like to verify that they're unavoidable before I do.
NestedGenericHolder, as above, cannot be registered any more than my original example (for the same reason). My first thought is to make GenericHolder implement CompositeDataView and define how it should be converted to CompositeData. The modified GenericHolder looks something like:
    public static class GenericHolder implements CompositeDataView {
        public GenericValue<Float> getGenericVal() {
            return new GenericValue<Float>(1.0f);
        @Override
        public CompositeData toCompositeData(CompositeType ct) {
            try {
                List<String> itemNames = new ArrayList<String>();
                List<String> itemDescriptions = new ArrayList<String>();
                List<OpenType<?>> itemTypes = new ArrayList<OpenType<?>>();
                itemNames.add("genericVal");
                itemTypes.add(SimpleType.FLOAT);
                itemDescriptions.add("generic value");
                CompositeType xct =
                        new CompositeType(
                                ct.getTypeName(),
                            ct.getDescription(),
                            itemNames.toArray(new String[0]),
                            itemDescriptions.toArray(new String[0]),
                            itemTypes.toArray(new OpenType<?>[0]));
                CompositeData cd = new CompositeDataSupport(
                        xct,
                        new String[] { "genericVal" },
                        new Object[] {
                                getGenericVal().getVal()
                assert ct.isValue(cd); // check we've done it right
                return cd;
            } catch (Exception e) {
                throw new RuntimeException(e);
    }This doesn't help anything though because introspection still seems to inspect this class' attributes. ie: Even though I've manually defined how to convert to CompositeData, it still seems to want to verify that it could do it automatically if it had to. Anyway, my next fix, is to change the name of the "getGenericValue" method to "genericValue" so that JMX doesn't expect that "genericVal" should be an attribute of my type. (And then I will add it to the CompositeData as an extra item - as described in the CompositeDataView JavaDoc).
Registration now because (I believe) JMX refuses to convert an object to a CompositeData that contains no attributes. As a result, I attempt to fix this by adding another getter to my class:
    public static class GenericHolder implements CompositeDataView {
        // MXBean introspection rejects classes with no attributes.
        public Integer getOtherVal() {
            return 17;
        public GenericValue<Float> genericVal() {
            return new GenericValue<Float>(1.0f);
        @Override
        public CompositeData toCompositeData(CompositeType ct) {
            try {
                List<String> itemNames = new ArrayList<String>(ct.keySet());
                List<String> itemDescriptions = new ArrayList<String>();
                List<OpenType<?>> itemTypes = new ArrayList<OpenType<?>>();
                for (String item : itemNames) {
                    itemDescriptions.add(ct.getDescription(item));
                    itemTypes.add(ct.getType(item));
                itemNames.add("genericVal");
                itemTypes.add(SimpleType.FLOAT);
                itemDescriptions.add("generic value");
                CompositeType xct =
                        new CompositeType(
                                ct.getTypeName(),
                            ct.getDescription(),
                            itemNames.toArray(new String[0]),
                            itemDescriptions.toArray(new String[0]),
                            itemTypes.toArray(new OpenType<?>[0]));
                CompositeData cd = new CompositeDataSupport(
                        xct,
                        new String[] { "otherVal", "genericVal" },
                        new Object[] {
                                getOtherVal(),
                                genericVal().getVal()
                assert ct.isValue(cd); // check we've done it right
                return cd;
            } catch (Exception e) {
                throw new RuntimeException(e);
    }It now works, but not without a few compromises:
1. I have to implement toCompositeData(). This one isn't too big of a problem. I can certainly live with this.
2. I have to avoid method names that JMX will interpret as attributes when the return type are ones that it doesn't know how to convert to an OpenType. (I then add them into my MXBean, by adding them into the CompositeDataView I build.)
3. Such classes (GenericHolder) must contain at least one attribute with a type that can automatically be converted to an Open type.
I'd just like to make sure there aren't better solutions to the problems I described above.
Thanks and sorry for the overly long post,
Ryan

Page Attributes and Application Class Attributes

Hi, everyone,
I am quite new to BSP.
I have a question here:
what is the difference between page attributes and application class attributes of a bsp application? As they are both global attributes, there seems to be no big difference when we use them.
thanks a lot.
Fan

Hi Fan,
a BSP application can be made up of many pages.
A page attribute is visible only in the page it is associated with.
Attributes of the application class are visible from every page in that application.
Cheers

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

Problem with loading classes!!!

I am loading classes using
// Open File
InputStream jarFile = new BufferedInputStream(new FileInputStream(
pluginPath));
// Get Manifest and properties
Attributes attrs = new JarInputStream(jarFile).getManifest().
getMainAttributes();
jarFile.close();
// Read Main Class
String mainClass = attrs.getValue("Protocol-Class");
// Load all classes from jar file without giving classpath
URL url = new URL("jar:file:" + pluginPath + "!/");
JarURLConnection jarConnection = (JarURLConnection) url.openConnection();
URL[] urls = new URL[] {
url};
ClassLoader classLoader = new URLClassLoader(urls);
// Create new instance of protocol
Protocol protocol = (Protocol) classLoader.loadClass(mainClass).
newInstance();
I am loading classes one by one say a order A, B, C. In my case class c extends class A. So I am loading class A first and later B and finally C. But I am getting exceptions when loading class C that Class A is unknown.The following exception is thrown
java.lang.NoClassDefFoundError: com/a/A at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:537)
Please give me a solution to make it run.

You create a new class loader for each class. The class loaders are independent, and so the class hierarchies they load are independent. Class A loader by classLoaderOne doesn't see class B loader by classLoaderTwo - they are loaded into their own sandboxes.
Either load everything with one class loader or create the class loaders in a hierarchy. To create a hierarchy use the class loader constructor that takes a parent class loader as a parameter. One class loader may be easier because then you don't need to worry about loading order.

Accessing the attributes of a class using field symbols?

An option to pulll a variable into a user exit that otherwise would be out of reach is detailed [here|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/208811b0-00b2-2910-c5ac-dd2c7c50c8e8]
Can a similar approach involving field symbols or otherwise, be used to pull in the attributes of a class into the exit? For now, I'm trying to access the A_FRONTEND_INDEX attribute of the class CL_HRXSS_REM.
any ideas?
~Suresh

Hi,
Have you already tried (PROGRAM)(OBJECT)->A_FRONTEND_INDEX in your code? I prepared small testing scenario with two programs and it works.
REPORT zmv_test1.
FORM test.
FIELD-SYMBOLS: <fs> TYPE ANY.
ASSIGN '(ZMV_TEST2)zip->crc32_map' TO <fs>.
IF sy-subrc EQ 0.
<fs> = 'Test'.
ENDIF.
ENDFORM. "test
REPORT zmv_test2.
DATA: zip TYPE REF TO cl_abap_zip.
START-OF-SELECTION.
CREATE OBJECT zip.
PERFORM test IN PROGRAM zmv_test1.

Using reflection api to copy like named attributes of a class

Hi guys,
I have been hearing about this for a long time now. How can one copy like named attributes from one class to another using the reflection api??
Can anyone provide a small example, with code??

What I have to do? Why getDeclatingClass () returns null, but in dejasmin code

Outer$Inner naming convention is not used by JVM to get declaring class.
You need to have proper InnerClasses attribute (refer to http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#79996)
in the generated classes. Did you check using jclasslib or another class file viewer and verified that your .class files have proper InnerClasses attribute?

Generic counter with leading zeros

Good evening everybody,
I was searching the code of a generic counter with leading zeros, but I did not found anything over the Internet. Therefore, I code it all by myself.
I give you the code, it will maybe helps someone.
Only needed leading zeros are generated, which means the following sequences :
0 - 1 - 2 - ... - 7 for a max of 7,or
00 - 01 - 02 - ... - 23 - 24 - ... - 89 for a max of 89, or
000 - 001 - 002 - ... - 432 for a max of 432.
public class LeadingZerosCounter {
public String[] counters = null;
public LeadingZerosCounter(int maximum) {
    this.counters = new String[maximum];
public String[] init() {
    int maxLeadingZeros = 1;
    int index0 = this.counters.length;
    while ((index0 /= 10) >= 10) {
      maxLeadingZeros += 1;
    int counter = 0;
    for (int index1 = 0; index1 < maxLeadingZeros + 1; index1++) {
      while (counter < java.lang.Math.pow(10, index1 + 1)) {
        String stringCounter = new String("");
        for(int index2 = 0; index2 < (maxLeadingZeros - index1); index2++) {
          stringCounter = stringCounter.concat("0");
        stringCounter = stringCounter.concat(new Integer(counter).toString());

NOTE : the two return are mandatory.
Try maximum raised to a power of 10 and maximum raised to a power of 10 + constant in [1; 9] to understand.
If you find any solution to make it faster, please let me know.

I like Jos' idea better than mine (go figure - he's a better Javanista)....
public class Counter {
    private String pattern;
    private int count;
    private int max;
    public Counter(int max) throws IllegalArgumentException {
        if (max < 0) {
          throw new IllegalArgumentException("Max (" + max + ") must be a positive number");
        this.max = max;
        int len = String.valueOf(max).length();
        this.pattern = "%1$0" + len + "d";
    public boolean hasNext() {
        return count <= max;
    public String next() {
        String result = String.format(pattern, count);
        count++;
        return result;
    public static void main(String[] args) {
        // for demo purposes only;
        // replace with command-line arg parsing, if desired...
        String prefix = "picture_";
        String suffix = ".jpg";
        Counter c = new Counter(99);
        while (c.hasNext()) {
            System.out.println(prefix + c.next() + suffix);
        try {
            new Counter(-1);
        } catch (IllegalArgumentException e) {
            System.out.println("test: " + e.getMessage());

Nested-Generic Type with the same parameter as enclosing type?

Greetings. I want to write a nested generic type with the same type parameter as the enclosing type. For example, consider:
public interface BinaryTree<Type> {
     Node<Type> getRoot();
     interface Node<Type> {
          Type getValue();
          void setValue(Type value);
          Node<Type> getLeft();
          void setLeft(Node<Type> node);
          Node<Type> getRight();
          void setRight(Node<Type> node);
}In this example, I want Node to be specified to the same type as the binary tree's parameter specification. Does anyone know how to do that? I have tried several methods and am at a loss.
TIA

Is there any way to declare that? Essentially I want
the nested type to parameterize the enclosing type.I understand that but I don't think it's possible because of how java generics works.
This ,
SomeClass< SomeNestedClass<Type> >is wrong because you're supposed to give a formal type parameter within <> not an already defined type (like SomeNestedClass).
If you instead do
public class SomeClass<Type > {
    public static class SomeNestedClass<Type> {
}To think of the two Type as the same formal type parameter is semantically incorrect. Both the outer type and the inner type must be able to participate in variable declarations "on their own". Say you do
SomeClass<Integer> sc;Just because you did the above in which context is now SomeNestedClass supposed to be bound as SomeNestedClass<Integer>? To me this shows that SomeClass and SomeNestedClass cannot share the same formal type parameter.

Generic Datasource with Delta and functionmodule

Hi together,
who can help me ??
Ihave created a generic datasource with function module and
delta.
the extractor runs well while i use full update and also initialization.
If i start the delta extraction, the extractor crashed with short-dump.
the message is SAPSQL_INVALID_FIELDNAME
What can i do, and what is wrong.

Generic Attribute Access Pattern

Hi all,
I'd like to implement my BMP Beans with the Generic Attribute Access Pattern. So instead of using get/set methods I simply do get/put of the HashMap stored in the EJB.
Now my question is: how to I implement persitance of data on the DB with this pattern ?
Do I have to move the content of ejbStore into the method setAttributes(Map map) ? this way after calling setAttributes data is persited on the DB. But then what should I do with ejbStore? should I leave it empty?
thanks a lot
Francesco

The setAttributes method should set the attributes of the bean from the hashmap, not do
anything in the database itself. Your ejbStore method will take the attributes of the bean
and put them in the database. This is since you say you are using BMP. If you were using CMP
the case would be different.
