How to access the JAXB generated methods of Complex element

Hi all,
I am generating the java classes from the a XSD file which contains the Complex element , which again contains the simple elements. JAXB is generating the interface and public static class for the inner Complex element. But i not able to create the object of this inner class using the Object factory class. Then without object how can i access the setter and getter methods contained in this complex element.
My XSD file looks like -
<xs:element name="SSDecisionActivity">
<xs:complexType >
<xs:sequence>
<xs:element name="Id" type="xs:ID"/>
xs:element name="ConditionFlow">
     <xs:complexType>
     <xs:sequence>
     <xs:element name="Condition" type="xs:string"/>
     <xs:element name="DecisionCriteria" type="xs:string" minOccurs="2" maxOccurs="unbounded"/>
How shall i access the methods from the ConditionFlow (Complex element) like setCondition(....),getCondition().
If anybody knows plz tell me the way.

I'm a bit confused about this design approach.
[Bindable] public var storyList:IdmlStory = null;
The reason why the above line fails to compile in StoryList.mxml is that a variable of the same name already exists. You have specified a List with an id of storyList. The translation process will yield:
var storyList:List = new List();
and then fill in the properties.

How to access the application module4s methods.

I have deployed my business components to OAS and I am trying to use from the applet class the remote appMod. In local mode the connection returns moduleimpl, but now the return is a remoteinterface. How to use that as a moduleimpl??
Code is like this:
String ejbUrl = "oas://vader:8889/ProjectOAS/Project/ProjectModule";
// Setup the environment
Hashtable environment = new Hashtable();
// Turn JNDI on to OAS
environment.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "oracle.oas.naming.jndi.RemoteInitCtxFactory");
// Lookup the URL
Project.common.oas.ProjectModuleHome homeInterface = null;
try {
System.out.println("Creating an initial context");
Context ic = new InitialContext(environment);
System.out.println("Looking for the EJB published as 'ProjectOAS/Project/ProjectModule'");
homeInterface = ( Project.common.oas.ProjectModuleHome )javax.rmi.PortableRemoteObject.narrow(ic.lookup(ejbUrl), Project.common.oas.ProjectModuleHome.class);;

I am guessing that u r declaring inner class b as a member inner class in class a
in class c u have to instantiate class b
But objects of class b should always be bound with objects of class a
you can do it in this way
a obja = new a();
a.b objb = obja.new a.b();
and then call objb.area();
If the inner class is a static one then u can instatiate it
a.b objb = new a.b();
*No need to bind it with outer class's object.

How to determine the get/set methods of an element from the schema

Is there a way that I can obtain the java method call to an element using only the schema (maybe using SchemaTypeSystem, SchemaType, SchemaComponent)? For instance, as I traverse the schema is there a method that I can call that will return:
"getPurchaseOrder().getCustomer().getName()"
for the name element in the form of a string or some other representation?
Thanks in advance.

Sorry Manoj,
but i didn´t find out, why these programs should be able to solve my issue. They just display a picture using the CL_GUI_PICTURE control.
I am looking fo a way to resize a given control to the very maximum, so that it fills the whole SAPGUI window!
Thanks anyway...

How to access the attributes from a method

Hi,
Thanks to all who replied to my previous thread. Please let me know how to access the attributes in method of component controller in the view.
Let Component_method be my method in component controller which contrains few attributes like this
method component_method.
data : node1 type ref to if_wd_context_node,
        itab type standard type of mara.
endmethod.
I want to access the above attributes in method of view.
method view1.
wd_comp_controller->method_component( ).
????? how to access the data of the method_component?
endmethod.
Kindly help me out in the syntax.
Rgrds
Mahathi

Hi mahathi
You should define the parameters in the header, not in the body of the method:
You can define it as importing, exporting, changing or returning, as you need. For example, in SE80
Parameter             Cl.declar.          RefTo        Opt        Type ref
node1                    importing            X                          if_wd_context_node
itab                       exporting                                        mara
method_component().
" code here...
endmethod.
and when you have to call the method,
wd_comp_controller->method_component(
                EXPORTING     node1 = nodelocal   " not importing!!!
                IMPORTING      itab   = itablocal      " not exporting!!!
i think that it's this what you want, don't i?

How to access the *.java file corresponding to a TypeElement T?

Here is a problem:
How to access the *.java file corresponding to a TypeElement T from a AnnotationProcessor environment?
Let us say the hook method
public boolean process(Set<? extends TypeElement> annos, RoundEnvironment roundEnv)
is invoked with a TypeElement T such that T.getQualifiedname() = "a.b.c.X"
And the problem is how to locate the file that has the *.java source code for a.b.c.X?
That is the file that has the source code for a.b.c.X say "some/path/a/b/c/X.java"?
For simplicity, let us assume that TypeElement T corresponds to a top-level Java class.

Pinaki wrote:
That is not something you as the annotation processor author should be asking about. That is something you the person configuring the javac environment should set up via the -d option or its equivalent.
I strongly recommend using a separate output directory hierarchy.That is the way the current implementation is. The annotation processor takes a -Aout= <some directory path> to write generated output relative to a user-specified location (which defaults to the class output location).That is contrary to the design of the annotation processing facility. The intended use is for that information to be configured via options like "javac -d".
Additionally, IMO it is a serious configuration error to put generated files and input files, presumably tracked under version control, in the same directory. Interesting you said that. We are just running some "field trial" with these things and some users want them to be in the same directory of the original *.java files (especially when their source files are spread across many roots) .
Who knows what the user wants?The user does and the user is free to (mis)configure their environment however they like ;-) However, that is the user's option and the user has control of this via the javac command line. The annotation processor is not the proper place to configure this setting; see slide 7 of http://blogs.sun.com/darcy/resource/J1_2006-BOF-0606.pdf for some thoughts on different roles in annotation processing.
presumably tracked under version control, in the same directory.version control is another 'usability issues' that we are trying to get our heads around with this stuff. "To check-in or not?" - that seems to be the question. When presented these facilities without any cue, "the users" were divided -- some wanted them to be checked-in, some did not. The context where these generated files being used -- there exists some rationale to check them in a version control system.The right answer depends on the circumstances, but IMO generally generated files should not be checked in under version control, especially if they are derived from other source files. Checking in generated files of this nature just creates the opportunity for them to get out of date with the originating files.

How to access the photos on icloud

hi
how to access the photos which i saved in i cloud, from my iPhone 5,
Note: i do not use any PC. and i only have purchased 20 GB of space on an annual sub. so as to save my photos, and create space in my phone and now i am unable to access it,
please advise
thanks
xxv

There isn't really a way to "save" photos to iCloud currently with non-beta software.
iCloud is involved with photos in 2 ways -- backup and Photo Stream.
Backup of an iOS device includes Camera Roll photos but they cannot be viewed at iCloud.com -- the backup can only be used when doing a restore of an iOS device.
Photo Stream photos also cannot be viewed at iCloud.com; Photo Stream is designed as a method of transferring photos from one device to another and is not designed to store the photos. More info http://support.apple.com/kb/HT4486
There is a new feature -- "iCloud Photo Library" -- coming sometime after the iOS 8 release next week: http://www.macrumors.com/2014/09/12/apple-demotes-icloud-photo-library-beta/

OOABAP-How to access the protected methos from a class

How to access the protected methos from a class..There is a built in class..For tht class i have created a object..
Built in class name : CL_GUI_TEXTEDIT
method : LIMIT_TEXT.
How to access this..help me with code

hi,
If inheritance is used properly, it provides a significantly better structure, as common components only
need to be stored once centrally (in the superclass) and are then automatically available to subclasses.
Subclasses also profit immediately from changes (although the changes can also render them invalid!).
Inheritance provides very strong links between the superclass and the subclass. The subclass must
possess detailed knowledge of the implementation of the superclass, particularly for redefinition, but also in
order to use inherited components.
Even if, technically, the superclass does not know its subclasses, the
subclass often makes additional requirements of the superclass, for example, because a subclass needs
certain protected components or because implementation details in the superclass need to be changed in
the subclass in order to redefine methods.
The basic reason is that the developer of a (super)class cannot
normally predict all the requirements that subclasses will later need to make of the superclass.
Inheritance provides an extension of the visibility concept: there are protected components. The visibility of
these components lies between that of the public components (visible to all users, all subclasses, and the class itself), and private (visible only to the class itself). Protected components are visible to and can be used by all subclasses and the class itself.
Subclasses cannot access the private components particularly attributes) of the superclass. Private
components are genuinely private. This is particularly important if a (super)class needs to make local
enhancements to handle errors: it can use private components to do this without knowing or invalidating
subclasses.
Create your class inse24 and inherit this CL_GUI_TEXTEDIT
class in yours. You can then access the protected methods.
Hope this is helpful, <REMOVED BY MODERATOR>

How to access the mysql using ordinary command line in Azure Website?

Hi
I deploying Django project on Azure. I created project and MySQL db according this method: https://pytools.codeplex.com/wikipage?title=PollsDjangoSql . I can create tables using django command "syncdb" in Visual Studio. I see
db structure in SQL Explorer. All works. But now I need to get access directly to mysql. For example with a view to set encoding of some column, or set permissions, change user password, etc.
I found about many different tools and methods in Microsoft portal. But the purpose of these tools, how to install it and how to use it is a very entangled (After several attempts to find out what's what two weeks later I found on my computer
three dozen programs with unknown purpose. I doubt that I need to install so many tools to just add the user in mysql).
How to access the mysql using ordinary command line (or the same simple tool) in my case?

Hi pvgdrk,
To get access directly to a mysql database, you can use the commandline tool(open a cmd window-->type mysql the commadline ) or the
GUI MySQL workbench.
Since this is a question about MySQL, I would suggest you post your question in a dedicated MySQL forum. You will get more prompt response.

Reg - how to find the purpose of methods in a class

hi everyone,
           can u plz help me with how to find the purpose of methods in a class???????
a description abt the methods in a class??????
                    thx in advance,
regards,
balaji.s

Hi Balaji
Pls find some stuff.
reward pts if help.
The following statements define the structure of a class:
·        A class contains components
·        Each component is assigned to a visibility section
·        Classes implement methods
The following sections describe the structure of classes in more detail.
Class Components
The components of a class make up its contents. All components are declared in the declaration part of the class. The components define the attributes of the objects in a class. When you define the class, each component is assigned to one of the three visibility sections, which define the external interface of the class. All of the components of a class are visible within the class. All components are in the same namespace. This means that all components of the class must have names that are unique within the class.
There are two kinds of components in a class - those that exist separately for each object in the class, and those that exist only once for the whole class, regardless of the number of instances. Instance-specific components are known as instance components. Components that are not instance-specific are called static components.
In ABAP Objects, classes can define the following components. Since all components that you can declare in classes can also be declared in interfaces, the following descriptions apply equally to interfaces.
Attributes
Attributes are internal data fields within a class that can have any ABAP data type. The state of an object is determined by the contents of its attributes. One kind of attribute is the reference variable. Reference variables allow you to create and address objects. Reference variables can be defined in classes, allowing you to access objects from within a class.
Instance Attributes
The contents of instance attributes define the instance-specific state of an object. You declare them using the DATAstatement.
Static Attributes
The contents of static attributes define the state of the class that is valid for all instances of the class. Static attributes exist once for each class. You declare them using the CLASS-DATA statement. They are accessible for the entire runtime of the class.
All of the objects in a class can access its static attributes. If you change a static attribute in an object, the change is visible in all other objects in the class.
The technical properties of instance attributes belong to the static properties of a class. It is therefore possible to refer in a LIKE addition to the visible attributes of a class through the class component selector or through reference variables, without prior creation of an object.
Methods
Methods are internal procedures in a class that define the behavior of an object. They can access all of the attributes of a class. This allows them to change the data content of an object. They also have a parameter interface, with which users can supply them with values when calling them, and receive values back from them The private attributes of a class can only be changed by methods in the same class.
The definition and parameter interface of a method is similar to that of function modules. You define a method meth in the definition part of a class and implement it in the implementation part using the following processing block:
METHOD meth.
ENDMETHOD.
You can declare local data types and objects in methods in the same way as in other ABAP procedures (subroutines and function modules). You call methods using the CALL METHOD statement.
Instance Methods
You declare instance methods using the METHODSstatement. They can access all of the attributes of a class, and can trigger all of the events of the class.
Static Methods
You declare static methods using the CLASS-METHODSstatement. They can only access static attributes and trigger static events.
Special Methods
As well as normal methods, which you call using CALL METHOD, there are two special methods called constructor and class_constructor that are automatically called when you create an object or when you first access the components of a class.

I've tried but its not working u have any idea Plz help me out...
The scenario is I have my portal running in my machine & appserver(weblogic) running in remote and want to access that appserver
thru Remote EJB from my portal. I have tried with the t3 protocol and iiop but it is not working
The code i have use
Properties props = new Properties();
props.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
props.put(javax.naming.Context.PROVIDER_URL, "t3://10.1.87.46:7031");
it is giving me a nullpointer exception when i try to access the method in the ejb , it is not able to call that method...
Plz help me out to resolve this situation
Thnx in Advance.....

SanjayBala, just so you know that it is possible to create a database link in Oracle to non-Oracle databases in some circumstances. Look up Generic Connectivity aslo know as Heterogenous Services. With 11g Oracle has basically renamed the feature and replaced it with somethinkg named ike DG4ODBC.
I have not spent time studying the details for DB4ODBC but with HS Oracle provided the interface and you had to obtain the necessary ODBC driver on your own. I had Oracle on AIX reading and writing to SQL Server on Windows but the developers chose to write a java program and connect to both via it. On Windows and Linux platforms the necessary ODBC drivers might be available without the requirement to go out and purchase one.
The Oracle Open Gateway product is an advanced version of the above features with drivers for specific non-Oracle databases included like DB2 or Informix.

In VB Programming code -- How to access the formula for suppressing a field

In VB Programming code -- How to access the formula for suppressing a field
I am using Crystal Reports 2008 v1
Using VB code, I am attempting to modify a Crystal Report before exporting it into a PDF format and then displaying it on the Web.
My problem is that I am unable to access the formula used to dynamically suppress a field.
The following code is working:
mySections = rd.ReportDefinition.Sections
For Each mySection As CrystalDecisions.CrystalReports.Engine.Section In mySections
   ' myFieldToChange is a String set to the text of the field I need to adjust the Suppression
   iloop = 0
   For Each RecObj As CrystalDecisions.CrystalReports.Engine.ReportObject In mySection.ReportObjects
           If mySection.ReportObjects.Item(iloop).Name.ToLower = myFieldToChange Then
               myTextObject = CType(mySection.ReportObjects.Item(iloop), CrystalDecisions.CrystalReports.Engine.TextObject)
               myTextObject.Text = "new field text goes here"
               mySection.SectionFormat.EnableSuppress = True
               ' Here is where I want to change the formula for the Suppression
            End if
            iloop = iloop + 1
    Next
Next
I can not find any reference to the actual suppression formula in the SDK help file.
Note, the EnableSuppress can be set to True for False, but if there is a formula for dynamic suppression, the True or False value is overwritten. The results of the formula determine the suppression.
Is there a way to reference this formula. I know that I can put on in using the Crystal Report Designer software, I need to modify this formula using VB code and the SDK.

Hello, Mark;
If you are using the ReportDocument object you do not have access to the Conditional Suppression formula. You can get around it by using a formula field in the report for the supression and then using the FormulaField code to change it at runtime.
If you want to change the supression condition directly at runtime you need to use RAS and the ReportClientDocument.
