Annotation Type Declaration

Why in anno type declaration some types look like methods ?
Example:
public @interface MyAnnotation {
   String doSomething();                   //HERE
   int count; String date();                 // int is fine but , String , why its a method ?
Usage:
@MyAnnotation (doSomething="What to do", count=1,
               date="09-09-2005")
public void mymethod() {
}

ya ..
it says
"The annotation type definition looks somewhat like an interface definition where the keyword interface is preceded by the @ character (@ = "AT" as in Annotation Type). Annotation types are, in fact, a form of interface, which will be covered in a later lesson. For the moment, you do not need to understand interfaces.
+The body of the annotation definition above contains annotation type element declarations, which look a lot like methods. Note that they may define optional default values.+ "
But does not explain why they are metods , observe in the above example that ,
primitive int is directly declared , not as a method ,
Then all should be methods ..

  • How to use %Type declaration with table residing in a different database

    How can I use the %TYPE declaration if the table is from a different database.
    E.g
    v_business_unit ps_jrnl.header.business_unit%TYPE;
    In the above declaration statement,the table 'ps_jrnl_header' resides in a different database(Database A) from the one I am currently in( Database B).(This is because data needs to be extracted from Database A into Database B).

    1. Create a database link to the other database (this probably already exists since your proc is interacting with that database)
    2. Create a synonym for the table in the other database
    create synonym foo for ps_jrnl.header@database_a;3. Reference the synonym in your variable declaration:
    v_business_unit  foo.business_unit%TYPE;

  • SAXParser type declaration not found - PLEASE HELP!!

    I am using XML to parse an incoming string of XML. I want to use an SAXParser to do this, but I cannot create an object of this type. I have the jar file jaxp.jar, xalan.jar, and crimson.jar in my classpath.
    Is there anything else that I need to do in order to get the parser to work.
    This is a very urgent need so any help is appreciated. Here is the error:
    Class SAXParser not found in type declaration;

    I have figured out the issue. Thanks for the help. I do have one more issue though. I am trying to parse a string of xml data and I need to pass my parse() method an InputSource object that I guess I will make from my incoming String.
    Any thoughts on how to do this?

  • Wildcards in type declarations or only methods?

    Can you declare wildcards in type declarations such as:

    ^
    2 errorsWhat am I doing wrong [if anything]?
    TIA
    -- Kraythe

    public class ListManager<List<?>> {
    }When I try this, I get the following compiler errror:Hmm .. I was thinking about this. .. What i was trying to declare was a class that would use as a parameter any declaration of a List. So what I want is a class that will take List<Integer> and List<String> and so on. So the result would be to use it like this:
    public void someMehtod() {
        ListManager<List<String>> strListMger = ...
        ListManager<List<Integer>> strListMger = ...
    }So if not with the wildcard, how is this accoplished (if it can be accomplished at all).
    I would also like to do something like:
    public class ListManager<Type extends List<?>> {
    }In this manner I would at least have access to the type. Except the extends is a misnomer since i want type to be any List<> type.

  • "Global Type declaration duplicated", cached xsd conflicting in jdeveloper?

    We're having problems recompiling a project after changing a schema in a second project on which it depends:
    Our HR composite app imports a schema from our FaultHandler app. I added 2 new elements to the FaultHandler schema and redeployed to the server - now our HR composite app won't recompile. It errors saying:

    Redepoy Fault Handler
    Clean HR app
    Make HR app
    We have the issue in both jdeveloper 11.1.1.3.0 and 11.1.1.4.0

    If your schema contains any characters which will be escaped when parsed by a browser, then version present in the actual .xsd and the version referenced via HTTP server will be different causing the issue.
    If you can post the content of your actual schema (as you see it in jDev and not the one opened in the browser) here it will help identifying the issue if any.

    i've an sql/plsql web service that return complex data type as xml
    in order to access the webservice in my application i generate webservice cproxy clinet java class

    now i go the proxyclinet.java class to execute the web service method the result is returned as string which is need to be parsed as xml nodes which is ok
    now suppose that i want to do another solution that is based on the Annotation Type XmlType to define a class to store the return data type as java object fro the xml data
    the
    java code as follow

  • Adding XML Declaration and Document Type Declaration.

    I'm using Oracle's XML Class Generator C++ version 1.0.2.0.0. I can create classes from a defined external DTD and create my XML document. But the document does not contain the XML Declaration <?xml version='1.0?> nor does it contain the Document Type Declaration <!DOCTYPE root-element-name SYSTEM "system-identifier">. What do I need to do to get these as part of my XML document? Does the class generator have methods to do this? Could someone show me an example?

    If you invoke the print method on the top-level ELEMENT, you get
    just the body of the document with no DTD or XMLDecl. if you invoke
    print on the top level NODE (the DOCUMENT node), then the output
    document will contain the XMLDecl and DTD.
    So please try to print from DOCUMENT node.

  • Global Type declaration/definition of name duplicated error

    Hi, All,
    We have two EJB exposed as the Webservice , so WS-1 and WS2, When I insert these two WS into the SOA Application to used by BPEL process. I get the compile error from jdev(11.1.1.1.3) like this:
    Global Type declaration/definition of name '{http://mynamespace-here/oracle}SearchParameter' are duplicated at the following locations:
    EJB WS1 xsd line ***
    EJB WS2 xsd line ***
    SearchParameter is bean SearchRequest‘s property, this bean is shared using in two EJB method interfaces.
    Our class design like this:
    @XmlRootElement
    @XmlType(name = "SearchRequest",
    namespace = " http://mynamespace-here/oracle ")
    public class SearchRequest
    implements Serializable
    private SearchInterface searchCriteria;
    @XmlElements(value =
    { @XmlElement(name = "SearchParameter",
    type = SearchParameter.class) })
    public SearchInterface getSearchCriteria()
    return searchCriteria;
    At here SearchInterface is an empty interface and SearchParameter is a class implement this interface.
    I feel @XmlElement in fact cause this duplicated error.
    So in this case, how can we expose this SearchInterface/SearchParameter through the XML properly?
    Thanks .

    If the message type in the external service and the one using in your local are using the same schema, could you check whether the external service has changed the schema in any way? Adding new fields, changing the field name, or changing the namespace? We had faced this issue before, and it was because the schema in our mds is different from the schema from OSB, which they changed it after we get the artifacts and we didn't have the updated schema in our mds.

  • PDF Custom Annotations Types?

    Can some kind reader comment and/or point to documentation on PDF's Custom Annotation Types?
    I was first introduced to those by Aandi Inston's reply to my "Click to Dial Plugin" posting.
    Unfortunately, such posting seems to have been pulled (lost?, relocated?, bitbucketed?) from the forum.
    My objective is to programmatically insert several links of different types in my PDF files. I intend to have a type for voice phone numbers, another for fax numbers, and yet another company or client ID, etc.
    The part below refers to a plugin (to be written).
    Later on, when the user clicks on a phone number, a call will be placed, clicks on a fax number will result in the document being faxed, while a click on an ID will result on a database lookup.
    I don't want to go through the hassle of studying the page's geometry to determine whether a phone number is voice or fax. I am just looking for a way to mark the different links, giving each one of them a type, which will be passed to the plugin upon a link being clicked.
    I recall that Aandi's explanation made an exact match for my application, but as I said before, his posting is gone.
    -Ramon

    Perhaps the use Custom Annotation Types (CAT) is an overkill? It seems that when a CAT is defined, an annotation handler has to be registered, and such handler provides the drawing. In my case I don't need any custom drawing. I just need to mark somehow the different links, assigning a type to each.
    Thanks for sharing your expertise, and helping the PDF format to become more useful and widespread...

  • Global Type declaration/definition are duplicated

    and below that there are numerous errors. I believe those are due to this first line. where am i going wrong?
    Regards.

    It looks like your local orsmds store and your server's oramds store are out of sync.
    To be sure, check the differences in WorkflowTask.xsd file at the following locations
