JAXB and binding

Hi all
I have a schema a.xsd that references another schema b.xsd.
I generated the binding classes for b.xsd now I want to generate the classes for a.xsd.
The problem is that xjc generates the binding classes for a.xsd, including the external ones included in b.xsd.
How can I solve this probem?
How can I tell xjc to point to an existing package for a set of already generated classes?
Thanks
Marcello

hi JAXB specification does not support full W3C schema
support in version 1.0.
u cant do "any"

Does BEA WLS 7.0 or 8.1 support JAXB and JAXR?

Hello
Does BEA WLS 7.0 or 8.1 support JAXB and JAXR?
Thanks

Hi a,
The short answer is no B or R yet, but stay tuned.
The somewhat longer story is that we are very much engaged with this
emerging binding standard to be used inconjuction with and beyond the
built-in types specified in JAX-RPC 1.1, it should be seen as a
compelling story for J2EE if JAXB could be used as a mechanism for
extending type mapping and offer a vendor neutral way to deal with user
defined types and to easily utilize user types that are developed for
XML applications in web services.
Concerning JAXR, I've experimented with SUN's RI using our UDDI server
and it works fine. As to the arguable merits of JAXR, all I can say is
that it is part of J2EE 1.4.

JAXB dynamic Binding ?

Hi,
I'm developing a geospatial application intended to use data shared through GML. GML specs defines a set of xml components to be used to define domain specific features that contain spatial information and / or contextual information. These features should be defined in their own schemas.
My app should be able to read whatever gml data fed to it (assuming this data is valid). For this purpose I used JAXB to bind GML components. But as those components are embedded in a top-level virtually unknown schema, I don't know how to handle that.
I hope i explaned well the issue :) and I hope someone could help me with this !
Thanx a lot.

Hi Marc,
I have one question regarding the use of <xsd:anyType>, Before that let me clear our requirement. We are trying to create a BPEL flow (Consumer) which has the ability to call other webservices (Producers) dynamically. There can be a number of Producer Webservices performing the same task. The end user should be able to add new Producer Webservices and remove already existing ones. We achieved this using EndPointReference (http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html) but the problem with this approach is that all the producer webservices have to work on a common schema. We want to support webservices working on different payloads.
My understanding is that when we map the XML document to xsd:anyType in the service's WSDL file, the producer web service need to have an implementation of this type in for of a java class. Is this correct ? Or can we provide the java implementation in our code itself? Can you please point me to some detail documentation on xsd:anyType?
Thanks

Apache axis, JAX-RPC, JAXR, JAXM, JAX-WS, JAXB, and Metro

Are all of the following the different APIs for creating web service applicaton?
Apache axis,
JAX-RPC,
JAXR,
JAXM,
JAX-WS,
JAXB, and
Metro
--If so, which one(s) are most widely used?
--If not, what are the differences among them?
Thanks
Scott

I think your are looking for a full web services framework.
Apache axis --> Is a WS framework. implements jax-rpc. Provides some features on its own
JAX-RPC --> Is a WS framework specification. Your application servers/axis implement this.
JAXR --> not an web-service api, rather a web-service registry access api
JAXM --> Is an api for xml messaging. Your framework provider may use this.
JAX-WS --> Is jax-rpc 2.0. Your application server provider will give implementation for this. Otherwise you can use xfire/metro as the implementation. Chose this over jax-rpc.
JAXB, --> Is used for xml-java binding. Jax-ws uses this. But not specific to jax-ws..
Metro --> Reference implementation for jax-ws.
All in all jax-rpc, jax-ws and axis2 are three options. go for jax-ws if you do not have any other constraints.As for selcting implementation of jax-ws, if you are working on an app-server (and not on a simple servlet container or without a server), server vendor will provide that. Otherwise look for xfire or metro.

Dynamic sql and bind variables

Hi,
I have a stored procedure which filters a table on 5 five columns. The filters come from the input parameters,
and these 5 parameters can come in any combination, I mean some of them may be null and some of them may not be null.
So I constructed the where filter of the query with IF blocks like the following:
dynamic_query := 'select * from TESTTABLE where 1= 1';
IF (P1 is not null) THEN
dynamic_query := dynamic_query || ' AND column1 = :1';
END IF;
IF (P2 is not null) THEN
dynamic_query := dynamic_query || ' AND column2 = :2';
END IF;
IF (P3 is not null) THEN
dynamic_query := dynamic_query || ' AND column3 = :3';
END IF;
IF (P4 is not null) THEN
dynamic_query := dynamic_query || ' AND column4 = :4';
END IF;
IF (P5 is not null) THEN
dynamic_query := dynamic_query || ' AND column5 = :5';
END IF;
OPEN CUR_OUT FOR dynamic_query USING P1, P2, P3, P4, P5;
The problem is how can I construct the USING and bind parameters, I cannot use "USING P1, P2, P3, P4, P5" because some of bind variables
may not be in dynamic query if the input parameters are null. Is there a way to overcome this problem without writing all the 2 ^ 5 combinations?
Any help is greatly appreciated.

here it is in the Tomer Cohen way:
IF (P1 is not null) THEN
dynamic_query := dynamic_query || ' AND column1 = :1';
ELSE
dynamic_query := dynamic_query || ' AND :1 IS NULL';
END IF;
IF (P2 is not null) THEN
dynamic_query := dynamic_query || ' AND column2 = :2';
ELSE
dynamic_query := dynamic_query || ' AND :2 IS NULL';
END IF;
IF (P3 is not null) THEN
dynamic_query := dynamic_query || ' AND column3 = :3';
ELSE
dynamic_query := dynamic_query || ' AND :3 IS NULL';
END IF;
IF (P4 is not null) THEN
dynamic_query := dynamic_query || ' AND column4 = :4';
ELSE
dynamic_query := dynamic_query || ' AND :4 IS NULL';
END IF;
IF (P5 is not null) THEN
dynamic_query := dynamic_query || ' AND column5 = :5';
ELSE
dynamic_query := dynamic_query || ' AND -1 = :5';
END IF;
OPEN CUR_OUT FOR dynamic_query USING P1, P2, P3, P4, P5;Amiel Davis

Creating and Binding View Objects dynamically : Oracle Jdeveloper 11g

Hello,
We are trying to create and bind view objects dynamically to adf data visualization components.
The view object is a result of multiple tables.
We are using Oracle JDeveloper 11g Technical Preview. ( can't upgrade to TP2 or TP3 now).
We have found this : http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html on our search for the same.
The sample application however, is in 10g , hence required migration.
Also, it was a standalone application with the TestClient.java having a main() method.
Our requirement is for Web Application; we use Adf+jsf .
Guidance of any sort is very much appreciated.
Thanks in advance.
-Anil Golla

Hi,
there also exist a forum for JDeveloper 11: JDeveloper and OC4J 11g Technology Preview
What you are trying todo is not trivial because you need to not only dynamically create the VO, you would also dynamically need to create the binding meta data for it (assuming you use ADF). Not sure if the API to modify the binding is public, so posting it on the JDeveloper 11 forum bears a glimpse of hope for an answer
In JDeveloper 10.1.3 you can't do this

Regarding Value and Binding properties of af:inputTextBox

Hi All,
I am using JDeveloper 11.1.1.6.0. I want to set the value for af:inputTextBox from the backing bean.
I observed there are two properties for this component, 'Value' and 'binding'.
So, I thought of using 'Value' property. For this I created a property in my backing bean.
Number textBoxValue; //Setter and getter methods for this ( I want to display numbers ans persist the same thats whay i have given as Number)
and in one of my methods I had given,
textBoxValue = new Number(12);
I am able to display the value in the UI
Here goes my queries, please clarify these.
1) What is the need of these two properties?
2) How can set value using the 'Binding' Property.
3) Can I set value to the input using both properties?
4) If 2nd point is correct then what will happen, if I set two different values to the textbox using these two components.
Thanks & Regards,
Ravi.

1) Binding is uses as an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
Value represents the value of the component. If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode.
So they are different.
2) You don't
3) You don't
4) as 2) in not correct this is not relevant
If you want to set the value of a ui component from inside a bean you have different possible solutions. Lets assume you have a binding for The component to bean. In case of a input text the bean property would be of type RichInputText. Lets the property name be myIPT. Then you set the value as myIPT.setValue("YOUR VALUE"); (if the component shows text).
If you have bound the value property of the component to a bean attribute (using EL) you only need the change the bean attribute.
If the value is bound to a value binding (e.g. one that was generated by dragging a VO onto the page and dropping it as form), you get the the value binding by
// GET A METHOD FROM PAGEDEF AND EXECUTE IT
// get the binding container
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
// get an ADF attributevalue from the ADF page definitions
AttributeBinding attr = (AttributeBinding)bindings.getControlBinding("NAME_OF_THE_ATTRIBUT");
attr.setInputValue("test");Timo

Binding? Aren't you talking about JSF? That term doesn't occur in JSP world.

Nested Repeater and Binding Problem - Please Help

I have nested repeaters and binding seems to work with the
outer repeater, but not with the inner repeater. I have boiled it
down to a pretty concise case. If someone could offer hints I would
be most appreciative!
I understand the objects I am using to store data could be
different, but it only looks strange because I had to boil down a
complex case to a simple case.
Type a user and then an email address then click to add them,
the user TextInput and label gets created, but not the email
address label and text input.
Basically I want users in an ArrayCollection, and their
multiple email addresses in an ArrayCollection stored in an Object,
where I get that email ArrayCollection using the user as the key to
the object acting as an associative array.
The attached code should compile fine, so please have a go at
this. Thanks!

I wouldn't bind to methods like that...I'd make properties
and bind to
those.

PreparedStatement and bind variable

We are experiencing some werid performance break downs where database server looks healthy and our java applications are down to their knees.
I was wondering if someone could help me clarify the comparison between PreparedStatement and bind variable. When I execute a PreparedStatement in java through the JDBC thin driver, would the database consider it a dynamic SQL or is it a SQL using bind variable? If this same statement is executed 100000 times, is it parsed 100000 times? We are using JDK131. How does it work?
Is there any memory leak in PreparedStatement implementation in JDBC thin driver? Is there any known symptom to this problem? What is the recommended solution?
Thank you very much!

If PreparedStatement is parsed and cached, why is there setting to set implicit statement caching and explicit statement caching? Our DBA insists that it is parsed every single time. How would I find out for sure?
The SQLs have not been changed. This sudden performance degradation started when a new client went live and we experienced higher than usual volumn. We are connecting using JDBC thin client from weblogic server to Oracle 8.1.7. It's been happening everyday since the client went live and the only way to get the performance back is to shutdown and restart the database server.
I tried to search JDBC related issues. The only complain that I've found so far is that there may be some potential memory leak for a PreparedStatement. However, I have not found anything from Oracle's website that concurs to that.
What is my best bet?

Convert row to columns and bind with same ID

I have a table with 2 columns - ID as Int and ClientID as Varchar(max)
ID        ClientID
1         123,784

3         111
4         982,543,212,453
I want t-sql to get output like this..Whenever there is a comma, split them and bind it to same ID.
ID        ClientID
1         123
1         784
2         342
2         891
2         322

4         982
4         543
4         212
4         453
Create statement:
Create Table Sample
( ID Int null , ClientID varchar(max) null)
Insert statement:
Insert into sample (ID,ClientID) Values (1,'123,784')
Insert into sample (ID,ClientID) Values (2,'342,891,322')
Insert into sample (ID,ClientID) Values (3,'111')
Insert into sample (ID,ClientID) Values (4,'982,543,212,453')

You can also do this using a user defined table valued function like this:
create FUNCTION [dbo].[ufn_SplitString_Separator](@InputStr VARCHAR(max), @Separator VARCHAR(1))
RETURNS @tmpTable TABLE (OutputStr VARCHAR(max))
AS BEGIN
DECLARE @TmpPOS integer
SET @TmpPOS = CHARINDEX(@Separator,@InputStr)
WHILE @TmpPos > 0 BEGIN
IF @TmpPos > 0 BEGIN
INSERT INTO @tmpTable VALUES (LTRIM(RTRIM(SUBSTRING(@InputStr,1,@TmpPos-1))))
SET @InputStr = SUBSTRING(@InputStr, @TmpPOS + 1, LEN(@InputStr) - @TmpPos)
SET @TmpPOS = CHARINDEX(@Separator,@InputStr)
END ELSE BEGIN
INSERT INTO @tmpTable VALUES (LTRIM(RTRIM(@InputStr)))
SET @TmpPos = 0
END
END
IF LEN(@InputStr) > 0 BEGIN
INSERT INTO @tmpTable VALUES (LTRIM(RTRIM(@InputStr)))
END
RETURN
END
And get the results:
DECLARE @Sample TABLE ( ID Int null , ClientID varchar(max) null)
Insert into @sample (ID,ClientID)
VALUES
(1,'123,784'),(2,'342,891,322'),(3,'111'),(4,'982,543,212,453')
select id, outputstr as clientid from @sample cross apply dbo.[ufn_SplitString_Separator](clientid,',')

Dynamic creation of ItemListBox and binding a child node

Hello @all,
I have the following context structure
root
--category
-- --report
-- -- --id
-- -- --name
-- --id
-- --name
the parent node is "category" with attributes "id" and "name" and the child node is "report" with "id" and "name".
Now I want on an onAction-Event of a Button, that for every category an itemListBox will be created with the according report names. the creation of the itemList is not the problem, but the binding of the datasource and/or the descriptivetext.
my code:
public void initItemListBox( )
    //@@begin initItemListBox()
    IWDView view = wdContext.currentContextElement().getSelectView();
    IWDGroup group = (IWDGroup) view.getElement("ItemListGroup");
    if (group.hasChildren())
      group.removeAllChildren();
    for (int i = 0; i < wdContext.nodeCategory().size(); i++)
      ICategoryElement catEl = wdContext.nodeCategory().getCategoryElementAt(i);
      wdContext.nodeCategory().setLeadSelection(i);
      generateItemLists(wdContext.currentContextElement().getSelectView(), wdContext, catEl);
    //@@end
public void generateItemLists( com.sap.tc.webdynpro.progmodel.api.IWDView view, de.mgi.portaldev.bc.mdw.msi.wdp.IPrivateCRSReportView.IContextNode wdContext, de.mgi.portaldev.bc.mdw.msi.wdp.IPrivateCRSReportView.ICategoryElement category )
    //@@begin generateItemLists()
    //    ItemListBox
    IWDGroup group;
    IWDGroup catGroup;
    IWDLabel label;
    String groupId = "group_" + category.getName();
    catGroup = (IWDGroup) view.createElement(IWDGroup.class, groupId);
    IWDMatrixLayout matrLayout = (IWDMatrixLayout) catGroup.createLayout(IWDMatrixLayout.class);
    String labelId = "label_" + category.getName();
    label = (IWDLabel) view.createElement(IWDLabel.class, labelId);
    label.setText(category.getName());
    IWDMatrixData layout = (IWDMatrixData) label.createLayoutData(IWDMatrixData.class);
    layout.setVAlign(WDCellVAlign.TOP);
    String itemListId = "itemList_" + category.getName();
    IWDItemListBox itemListBox = (IWDItemListBox) view.createElement(IWDItemListBox.class, itemListId);
    label.setLabelFor(itemListId);
    IWDMatrixData itemlayout = (IWDMatrixData) itemListBox.createLayoutData(IWDMatrixData.class);
    itemListBox.bindDescriptiveText("crsReporting.category.report.name");
    IWDNodeInfo reportNodeInfo = category.nodeReport().getNodeInfo();
//    itemListBox.bindText(reportNodeInfo.getAttribute("name"));
    itemListBox.setVisibleItems(5);
    IWDMatrixHeadData matrixHead = (IWDMatrixHeadData) itemListBox.createLayoutData(IWDMatrixHeadData.class);
    IWDAction itemListAct = (IWDAction) wdThis.wdGetItemSelectAction();
    itemListBox.setOnLeadSelect(itemListAct);
//    itemListBox.bindDataSource(reportNodeInfo);
    itemListBox.bindDataSource("crsReporting.category.report");
    catGroup.addChild(label);
    catGroup.addChild(itemListBox);
    group = (IWDGroup) view.getElement("ItemListGroup");
    group.addChild(catGroup);
    //    END ITEMLIST
    //@@end
What am I doing wrong? in every ItemListbox there are only the report names of the last category.
thanks.

RowRepeater is available in WD Java since NW CE (7.1). With RowRepeater, the solution is trivial and can be done completely by declaration in view designer.
In earlier releases, you can solve it as follows (non-trivial)
- For each category, create a separate context node "Category_i" with an attribute "name"
- Inside each category node, create a non-singleton node "Reports" with an attribute "name"
- Foreach report, add a node element to the reports subnode of its category node <b>element</b>
All this has to be done using the generic context API.
On each change of the data, reset the context and re-create these nodes.
In wdDoModifyView(), check if data have changes and create UI elements programmatically.
- For each category, create a group, bind header text to category name.
- Inside each group, create a ItemListBox, bind "dataSource" to reports sub-node of category (non-singleton!) and bind "text" to text attribute of report node.
Sample code:
To build context structure:
private void createCategories()
    for (int i = 0; i < 3; ++i)
      IWDNodeInfo categoryNodeInfo = wdContext.getNodeInfo().addChild("Category" + i, null, true, CMICardinality.ONE, CMICardinality.ONE, true, null);
      IWDAttributeInfo att = categoryNodeInfo.addAttribute("name", "ddic:com.sap.dictionary.string");
      IWDNode categoryNode = wdContext.getChildNode(categoryNodeInfo.getName(), 0);
      categoryNode.getElementAt(0).setAttributeValue(att.getName(), "Category #" + i);
      IWDNodeInfo reportNodeInfo = categoryNodeInfo.addChild("Reports", null, false, CMICardinality.MANY, CMICardinality.ZERO_TO_ONE, true, null);
      IWDAttributeInfo attReportName = reportNodeInfo.addAttribute("name", "ddic:com.sap.dictionary.string");
      IWDNode reportNode = categoryNode.getChildNode("Reports", 0);
      for (int j = 0; j < 5; ++j)
        IWDNodeElement report = reportNode.createAndAddElement();
        report.setAttributeValue("name", "Report #" + j);
To recreate UI:
if (<data_have_changed>)
      IWDTransparentContainer root = (IWDTransparentContainer) view.getRootElement();
      for (int i = 0; i < 3; ++i)
        IWDNode categoryNode = wdContext.getChildNode("Category" + i, 0);
        IWDAttributeInfo attName = categoryNode.getNodeInfo().getAttribute("name");
        IWDGroup group = view.createElement(IWDGroup.class);
        root.addChild(group);
        IWDCaption header = view.createElement(IWDCaption.class);
        group.setHeader(header);
        header.bindText(attName);
        IWDNode reportsNode = categoryNode.getChildNode("Reports", 0);
        IWDAttributeInfo attReportName = reportsNode.getNodeInfo().getAttribute("name");
        IWDItemListBox list = view.createElement(IWDItemListBox.class);
        group.addChild(list);
        list.bindDataSource(reportsNode.getNodeInfo());
        list.bindText(attReportName);
