Support for Read Only EJBs ?
Hi;
I'm trying to discover if OC4J 9.0.3 provides support for Read Only Entity EJBs? If anyone can point me to docmentation on deployment descriptor elements controlling this, I'd be most grateful..
Thanks in Advance;
Simon
Simon -- We do support read-only concurrency in OC4J. Have a look at the EJB Developer's Guide (available on OTN) for more information. It is in the section on locking modes.
Thanks -- Jeff

SharePoint 2010 List View Web Part not showing for read-only users?
Hello all,
I have List View Webparts on my Blank Web Part page, and it's not showing for Read-Only users.
Is this intended by Microsoft or is it a bug?
Thank you!Hi,
According to your post, my understanding is that the read only user could not see the list view web part.
Per my knowledge, the issue may be cause that the user do not have the proper permission for the list.
1. Check whether the user can access the list.
2. Check whether the user can view all the items instead of partial items in the list.
3. Check whether there are some fields refer to other lists or terms, especially the lookup field or managed metadata filed.
If that is the case, make sure the user can access the lookup list.
Thanks,
Jason

Enter event not triggering for read-only checkbox
I have some objects in a form that get "locked" when the user signs the form. I'm not using the digital signatures. Instead, when the user types their name into the signature text field, a script runs on the change event that makes all of the fields in the form read only. It also unlocks the fields if the signature is deleted.
I was worried that we would get a lot of phone calls with users that didn't understand that the form had locked ("Why doesn't this form work?!"), so I added some code to the enter event for all of the fields that would pop up a messagebox to explain to people trying to edit a signed form that the form was locked and that they would need to delete the signature to edit the form.
This plan works perfect for my text fields and decimal fields. It does NOT work at all for my checkboxes. For some reason, the enter event is never triggered for read-only checkboxes. I don't see any other events that would obviously work for me though. Any ideas?
ThanksThanks, those are reasonable suggestions.
In the first suggestion, I'm unclear about one aspect of how I would accomplish this. I assume I would allow people to modify fields in the form, but that when they did, a msgbox would pop up that would inform them that, if they continued with this modification to a signed form, the signature would be removed. I'm all good to that point. But if they answered that they do not want to continue modifying that field and removing the signature, how can I code it to set the value back to what it was before the change? Is there some method that will give me access to the value of the field BEFORE the attempted modification? I went looking for something like $.previousvalue, but found nothing.
I'd suggest that I could use a two-stage solution, in which I store the previous value on the enter event, and save it just in case they do not want to change the field when prompted by the msgbox, but since the enter event does not exist for checkboxes (my original problem), that seems like it won't work.
As far as radio button suggestion, I like radio buttons very much except for one fatal flaw: they aren't (as far as I can tell) clearable. That is a shame. Clearly some people (like me) want both exclusivity AND clearability. And we'd like the controls to have an enter event. But I know I'm demanding Anyway, as it is, I just end up having to use checkboxes and create a boatload of silly code to make them exclusive.

Default value for Read-Only Picklist Field
Hi, all--
I would like to have a default value ("Undetermined") for the "Associated Account" read-only picklist value. I have an account record of this value for this purpose. This is because if there is no value in the field, the record will not be included in a report that includes the field. I do not want to make the field required at this point.
Field management doesn't appear to allow any default value for read-only picklists. Does anyone know how to get around this, either at the lead record stage or at the lead report stage (without resorting to an analytic, which won't work for what we are doing)?
Thanks.That's a great question. It doesn't appear as though you can select it from the typical method of Admin | Application Customization | Lead | Lead Field Setup | Associated Account.
Have you tried creating a workflow to populate the field using Before Modified Record Saved? -
Best practice for read-only functionality
Hi,
I'm part of the development team of a system with about 100 screens. The customer would like us to add some read-only functionality to the system, so that certain users are able to access the screens but not change any of the data on them. We already have policies in place on the database level that keeps read-only users from saving data, but it's not very user friendly to allow users to change data on a screen, only to tell them that they're not allowed to save those changes once they try to do so. It would clearly be better if all components are rendered as read-only components for read-only users, making them unable to make any data changes in the first place.
User privileges in the system are controlled by roles defined and set in the system (not ADF roles or Weblogic roles). At any given time and place, it's possible to check whether the current user has a certain role. We already use this in a number of places to make it possible to control which user has access to which screens. In a few places we even control which functionality should be enabled for the current user within a screen, but mostly the access control is currently on the screen level. With read-only users getting access to all screens, it seems we will need lot of extra in-screen access control to keep these users from changing anything.
But what's the best practice here? One way to go would be to add some logic to every single active component on every single screen, to determine whether it should be rendered as active or disabled/read-only. But that would require a lot of extra coding.
So my question is: Is there a smarter way to do this? Maybe something done through skinning? Or something else?
(I'm not sure how relevant this is for this sort of question, but we're currently using JDev 11.1.1.4.0, and expect to upgrade to 11.1.1.6.0 within the next 6 months)
Best regards,
AndreasHi Guna, Puthanampatti and Don,
Thanks a lot for your replies. I'm currently looking into implementing something along the lines of what Guna has suggested:
Our application consists of a number of individual work spaces that are deployed as adflibs which have all been added to a "master application work space", and the master application is deployed as an .ear file. Most of the individual work spaces are for all the different functional areas of the application, with their own task flows, page fragments etc. The rest are work spaces with common functionality, like datamodel (entity definitions), utility methods, page templates, and framework extensions. In the latter, we have defined custom classes for all the base classes (somewhat similar to what Don describes, I believe).
In our custom class for ViewRowImpl, I have added an isAttributeUpdateable method, and in our custom class for ApplicationModuleImpl I have added an isReadOnlyUser method. The isAttributeUpdateable method uses the isReadOnlyUser method to determine if the current user is a read-only user or not; if the user is a read-only user the isAttributeUpdateable method will return false, otherwise true. The isReadOnlyUser method in our base class is just a dummy method that always returns true. But in the ApplicationModuleImpl classes of our individual work spaces, i've written an override for isReadOnlyUser, giving the answer that is relevant for the work space in question (for instance, whether or not the current user has the role "User Administrator").
That pretty much takes care of all input fields in tables and forms, which is a big step in the right direction. This still leaves some work to be done for components that are not directly linked to view object attributes (like buttons), but I guess that can't be helped. Also, there are a few of the work spaces that contain a number of pages that are related to different user privileges (as in: page 1 requires user privilege A, and page 2 requires user privilege B); in these cases I will have to do something different than just writing an override in the "local" ApplicationModuleImpl class.
@Don: What you describe seems to be pretty close in functionality to what we already have, though your implementation is different from ours. You have used your custom base ApplicationModuleImpl class to keep read-only users from committing changes. We use Virtual Private Database and database policies to the same end: If a user without the required full-access role tries to commit data it will cause a database error, which we then handle in the application (so the user gets a message like "You don't have the required privileges to changes this data", rather than an ORA message). Unfortunately, our customers are not content with this. They want a solution where all input fields and most of the buttons etc. are disabled for read-only users, and that's why I'm looking into the best/smartest way to do this.
@Puthanampatti: We already use something similar to what you're suggesting. The challenge I'm currently facing is how best to disable/enable components based on the current user's roles, not how to determine and store those roles.
Best regards,

Invalid operation for read only resultset:
Hi.
I'm developing an app that connects to Oracle, but I ran into the following problem:
When I create a Statement, I specify
that I need an Updatable ResultSet with the following code:
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rset =stmt.executeQuery(somesql);
When I try to update the ResultSet, I get an SQLException: java.sql.SQLException: Invalid operation for read only resultset: updateString
Am I
doing something wrong or is this a bug?
Any info is greatly appreciated.
nullThere are limitations on the kinds of queries you can perform. If the query is not suitable for update, it reverts back to readonly automatically. Read the below article about limitations and examples.

Database open for read-only access ORACLE
while building a universe with a dblink betweens oracle databases, i try to create a derived table in the form
select field1 from table@db_to_db2
but i get the following message:
Exception: DBD, ORA-16000: database open for read-only acces State N/A.
I understand the statement "Set Transaction for read only" must be set before any transaction during the session, but still dont know how to trigger it in bo universe designer.
Can someone know how to solve it?I suggest you fill-in the BEGIN_SQL parameter on the Universe to turn on the read-only transaction.
Here is an excerpt from the Universe Designer guide:
The BEGIN_SQL parameter allows you to prefix SQL statements with the same parameters each time a SQL statement is generated.
1. Open the "Universe Parameters" dialog box in Designer.
2. Click the Parameter tab.
3. In the "Parameter" list, select the BEGIN_SQL parameter and enter the
appropriate prefix commands.
4. Save the settings.
5. Save the universe. -

Your result using 'SELECT *' is not updateable. Gimbal2 was pointing you in the right direction. You have to specify the columns in the select list to get an updateable result set.
You also need to use 'updateRow()' to update the database and have a commit somewhere to keep the results.
This code works for me. Note that I added an explicit SELECT list, the 'updateRow()' method and an explicit COMMIT.
try {
con = getOracleConnection();
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
// String query = "select * from employees";
String query = "select first_name from employees"; -- added explicit SELECT list
rs = stmt.executeQuery(query);
while (rs.next()) {
String fname = rs.getString(1);
if (fname.equalsIgnoreCase("Adam")) {
rs.updateString(1, "Mark");
rs.updateRow(); -- need this statement to actually update the database
// rs.updateString(2, "Robert");
break;
con.commit(); -- added explicit commit for testing
} catch (SQLException ex) {See Performing an UPDATE Operation in a Result Set in the 'Updating Result Sets' section of the JDBC Developer's Guide and Reference
http://docs.oracle.com/cd/B28359_01/java.111/b31224/resltset.htm#i1024720
As gimbal2 also alluded it is considered poor practice to use column numbers to perform result set operations when you don't know for certain what column a given number refers to. Before people start jumping all over that statement let me clarify it. The key part is KNOWING what column you are referencing. It is more performant to access result column columns by column number rather than by column name since the methods that take a column name call the integer method under the covers anyway but have to search the array of column names in order to get the column number.
With your query (SELECT *) there is no way to be sure the column order is the same since the table could be redefined with the columns in a different order or certain columns having been deleted. So for performance LOOP processing column numbers are used inside the loop but those column numbers are determined by using the metadata BEFORE the loop to convert column names to column numbers.
That way you code (BEFORE the loop) can use column names but you use a set of integer variables (one for each column) for the actual access inside the loop. -

This operation is not available for read only field 'Type MVF'
Hi All,
We are using OrderToCash PIP and we are on Siebel 8.1X.
While Synching the customer from Ebiz to Siebel facing the following issues:
Method 'WriteRecord' of business component 'Account' (integration component 'Account') for record with search specification '[Row Id] = "2d3434313239353"' returned the following error:"This operation is not available for read only field 'Type MVF'.(SBL-DAT-00402)"(SBL-EAI-04451)
Please suggest us what steps to be done in Siebel.
Thanks
MaanasaFirst check the process why this is calling Account BC WriteRecord(). The field "Type MVF" might be read only and this sync process is trying to update this field which is read only. This is the reason for the error. Check the OM log / EAI Obj Manager Comp log (set log level to 5) and check.

Hi
My first thoughts are
• iMovie ill behaving - Trash the iMovie pref file - use to set things right
• in reg. to Photos - Did You change iPhoto Photo Library - Then iMovie get's lost as it peeks into iPhoto on start up to see where photos are stored. Set iPhoto back to first Photo Library (when iMovie is not running) then start iMovie.

Primary Key for Read Only Entity Beans In EJB 3.0
Hi,
I have checked the spec for ejb 3.0 which mentions that, there is no common standard for the vendor to implement the Read only Entity Beans.
My question over here is how it is implemented in OC4J??
Do we need to specify a primary key attribute in the read-only entity bean?
w.r.t BC4J(ADF) i remember, we used to create a read-only View Object with out specifying a primary key.
Just want to check is that the way it works in EJB 3.0 (Implemented by OC4J).
Thanks for your help in advance.

Hello, I hope the experts here can advise me on which development approach for a new .net web application that I am to begin development shortly. I have the back end stored procedures complete and now I will build a .net front end.
This front end will be 95% populating custom html5/css3/jquery pages from c# DataSets which are themselves populated from calls to oracle stored procesures. There will be no updating - this is read-only querries of OLTP prpared tables off of a data
warehouse schema. I am a verteran at the back end stuff but my web app development skills are new so I hope to get a recommendation form the experts on what approach I should persue to build the front end. From what I have seen I might start
with MVC5 framework and build the web pages with RAZOR embedded c# code looping through the DataSets to create the html. I need to the ability to create very custom div elements throughout, so I understand I should not use some high level code generation
tool. Thanks so much for the feedback.Hello Jay,
This forum is discuss and ask questions about the C# programming language, IDE, libraries, samples, and tools.
>>I hope the experts here can advise me on which development approach for a new .net web application.

Using cache for read only data
In my application I have to display some read only data (in number of drop down present on several portlets)
this data might be driven from the database or from some XML/property file.Not decided yet.
for example : Country /state/City/Zip code etc..
Kindly let me know how can I implement the same in Weblogic Portal 10.0.
Do I have to use some third party caching mechanism like Hibernate cache for this
or
Weblogic portal do support caching ??
Please suggest the all possible soultions to implement this.Cache cache = CacheFactory.getCache("yourCache"); //any name can be passed, and you can create as many as you want , perhaps by functionality, perhaps by size etc. If you want to configure statically you must use this name in the xml file. If you define it in the xml file , you can administer the cache from Portal Admin
cache.put("key","value");
cache.get("key");
There are other advanced things you can do like Time To live / flushing / auto reload the cache which is all described in the javadoc
