Access wwv_flow_files objects through GUI

Can the files from wwv_flow_files be accessed through the GUI ?

Deltagamma,
It depends on what you mean by "accessed".
If you upload an image you will be able to see it in the list in HTML DB.
If you upload say, a large Word document, then to view it you would have to download it and view it in Word or use the MS Word plugin to view it in your browser.
If you simply want to upload and download documents or other files then I suggest you check out the How-To on that subject and try it out.
Probably best if you can explain exactly what it is you are trying to do then someone will be able to provide proper advice.

How do I access session data through an EJB?

Hi
How do I access session data through an EJB?
I am currantly developing a Web service (using ejb's, JBoss.net and Apache Axis). A client making a call to this Web service, is expecting a bussiness-object in return. My problem is that this bussiness-object i stored in a users session data. How do I retrieve this bussiness-object from the users session.
I have read that this does not work with httpsessions, is this true? If this is true, is it possible to store the bussiness object in a JavaBean e.g:
<jsp:useBean id="userContextWebImpl" scope="session" class="com.ac.march.client.UserContextWebImpl">
<%
String key = "test";
String value = "This is the value";
userContextWebImpl.setValue( key, value1 );
%>
</jsp:useBean>
and then retrieve this information through the EJB? Or is it possible to do this by using Statfull JavaBeans? Or can this be done through a nother solution?
Please help!

I have created a JavaBean with scope="application" to store some data. The data is stored when a user prefomes a spesific task.
A different person then makes a call to a Web-Service on the server. The Web-Service then asks an EJB to retrieve the data stored in the JavaBean (servlet cotext). In other words: How do I retrieve this data from the EJB?
I have tried with this code, but with no luck.
(ApplicationContextWebImpl is the JavaBean)
public static String getBookingResult( String key )
     String myResult = null;
     String myKey = key;
     ApplicationContextWebImpl applicationContextWebImpl = null;
     try
          applicationContextWebImpl = new ApplicationContextWebImpl();
          myResult = (String)applicationContextWebImpl.getValue( key );
     catch ( java.rmi.RemoteException e )
     return myResult;
}

Accessing wwv_flow_files changed after upgrading from 2.0 to 2.2

We have recently moved to 2.2 After the move uploading files, under some circumstances, failed.
Further investigation found that the upload was working fine, accessing wwv_flow_files table had changed in some way.
From the SQL Workshop we could see the files which had been uploaded. From SQL*Plus we couldn't see the same files.
I have read Re: Lost permissions on WWV_FLOW_FILE_OBJECTS$ and see at the end it says that access to wwv_flow_files is not supported from SQL*Plus. That's fine.
The problem we have is that the same limit seems to apply to functions called from within an APEX application. We have a function that at one point issues the following SQL -
SELECT blob_content
INTO l_blob
FROM wwv_flow_files
WHERE name = p_file_name;
(The function goes on to extract rows from the uploaded file to be uploaded into a table).
This function was not able to find the row which we knew was in the table.
Drilling down wwv_flow_files is a view of wwv_flow_file_objects$ with the following condition 'where security_group_id = wwv_flow.get_sgid'
By changing the original SQL to
SELECT blob_content
INTO l_blob
FROM WWV_FLOW_FILE_OBJECTS$
WHERE name = p_file_name
AND created_by = 'HTMLDB_PUBLIC_USER';
we get what we want.
My question is .. as the function is called from with an APEX application, why is the where clause preventing it from accessing the data we need.

Thanks for the details, it's making more sense to me.
The function extracts the rows from the uploaded file and displays them in a textarea.When you say "and displays them in a textarea" it sounds like something that happens during page rendering. But I think maybe your page selects the rows in an after-submit process and puts some content into a textarea item for display during the next page "show". Tell me if I'm on the right track. In 2.2, there's a bug that prevents queries from seeing the just-uploaded "files" or rows until after computations have fired. You need to move any code that selects those rows to a process "after computations and validations" (you could run it as a validation if you really needed to). Let me know if you think this explains what you're seeing. This is fixed, by the way, in 3.0.
The created_by = 'HTMLDB_PUBLIC_USER' clause is required as the >>WWV_FLOW_FILE_OBJECTS$ table also contains objects created by other users, for >>example ADMIN (eg APP imports etc)But your predicate specifies "where name=" and name has a unique constraint so you'll get the row you want without specifying created_by.

Accessing RMI Application through an Applet hosted on Apache web server

Hi All,
Just to let you know, I'm a complete novice at RMI. Ok, heres the story...I have an applet which is deployed on Apache Webserver (localhost), with the neccessary files needed for the RMI app in the same directory - htdocs(i.e. Applet class, RMI Interface, and Stub). I have the object server running on the same machine - which is in the directory C:/pumps. For the binding I'm using rmi://localhost/PumpService. I'm running the rmiregistry in the C directory. The problem is that when I access the applet through localhost(i.e. http://localhost/pumps.htm) it doesnt work, doesnt seem to access the remote object. However, if I directly load the html page from C:/Apache2/htdocs/pumps.htm - it works perfectly. Any ideas on the way I could get it working through the localhost?
Thanks...

The problem is that
when I access the applet through localhost(i.e.
http://localhost/pumps.htm) it doesnt work, doesnt
seem to access the remote object.Are the exception and the line of code you get it on a secret?

Thread safety bug in XPS Serializer or FixedDocument sequence? "calling thread cannot access this object..."

Every once in a while (500 iterations or more) I'm getting an exception in the static method below stating "calling thread cannot access this object because a different thread owns it". Thing is, this method references no external objects
and performs no special threading operations. All of the WPF objects are created and consumed in this method. The only aspect that is multi-threaded is that this method can get called concurrently on different threads in the same app domain (the
project is a Windows service). That said the fileToDecollate parameter will be unique every time, so there is no "collision" as far as that goes.
Any ideas?   This is maddening and in theory it should not be possible to blow this error.

I have opened a support case with Microsoft through my employer. I'm convinced there is some .NET framework code that is not thread safe. I did put together a test harness app that demonstrates the problem (within 30 seconds or so after
you start it) and I sent that to MS support. They're looking into it. Anyone else who is curious can download the sample project here:

Thru OEM get list of queries and their schemas that accessed my objects

Hi,
I have a list of objects on my schema and i need to track the list of sql queries by different users that accessed by object during this time period.
i haven't enabled any auditing yet.
is there any way i can get that list of queries and their schemas that accessed those particular objects during a particular time period through OEM.
Can someone guide me please.
Thanks in advance.
Philip.

create a name property in your class and assign a name property to your instances (either in the contructor) and/or using getters/setters. (you'll need a getter anyway.)

Accessing view object class (impl) method from bean (or vice versa)

Halo everyone, I am using JDeveloper 11.1.2.1.0
I have a UsersViewImpl class with a method which refresh the user table like below.
public void resetEmployeeSearch() {
removeApplyViewCriteriaName("viewCriteria");
executeQuery();
and I have a UserBean class with a method which reset the search fields values like below.
public void resetInput(ActionEvent actionEvent) {
........RichInputText = input ...
input.setValue("");
AdfFacesContext.getCurrentInstance().addPartialTarget(searchForm);
I would like to implement it in such a way that, once I press a button, both methods will be called.
I have tried to call from bean method using UsersViewImpl vs = new UsersViewImpl ..... which is wrong and wont work.
I have read about doing something like ViewObject vo = am.findViewObject("DeptView1") but I duno how to use it because I cant have a proper example.
Any suggestion on accessing view object class (impl) method from bean (or vice versa)?
Or is there any way to combine both method in the same class ?
Thank you :(

User, if you get class not found exceptions you need to tell us which classes you can't find. The JSFUtils and ADFUtils classes needing some other libraries which should already be part of your Fusion Web Application template (which your adf application should be based on). If you did not use this application template, you may have to add some libraries yourself.
What is the diff of using the ADFUtils and OperationBinding way?
The ADFUtils can get you access to the application module which you then use to call exposed methods on. The disadvantage of doing this is that you have to implement your own exception framework which then handles exceptions thrown by the application module. An other thing is that if you e.g. alter a VO which you use on the page this changes are not seen on the page until you refresh the page. The binding layer does not know about these changes so the iterators (which are used on the page to show the data) are not refreshed and so you don't see the changes.
In general you should avoid using the application modul in a managed bean method and always use the binding layer (OperationBinding) to call methods. This ensures that exceptions are all handled the same way and that changes to the data model are reflected in the GUI.

Accessing WSDL document through JAXR

I am trying to access the WSDL document of a web service through JAXR. Any has any idea how to get to it? I've used UDDI4J which has methods corresponding to each method in the UDDI API. I can't understand why the Sun WS package did not do the same thing. I mean why provide 1 API to connect to two different registries (ebXML, UDDI).
The WSDL service implementation is stored in the BindingTemplate of UDDI, whilst the service(s) interface is stored in the tModel. Anyone can tell me which are the objects / methods that map to getting the WSDL documents ?

I am also trying to figure out how to access specific WSDL information and am going through the spec again now to see if I have missed something.
Have you determined any way to at least retrieve the parameters (ie: String etc...) needed to access the service through the JAXR query API? Seems like a simple thing, though haven't found any methods which seem to do this...
Thanks,

Privileges for creating DB objects through portal

All,
I am a portal administrator and want to give portal access to a developer to create their own portal page against their own db schema. They would like to create db objects through the portal interface (i.e. tables).
My question:
What privileges/grants/roles do I need to give them to create db objects? Do I need to give them the DBA role? Do they need "Full Administrator" privileges within portal?
Thanks,
Jon.

Sorry, your question is not very clear. From what I got:
You want the privilege to be able to create DB Objects. For that:
you just need an End-User with "Manage" privilege on any of the "Schema".
