JNDI Viewer for OC4J

Does anyone know of any JNDI Viewer out there that could be used to view the JNDI Tree of one or many OC4J instances? Please don't say that there's one in the Enterprise Manager, or Mangler as we call it, as it isn't a runner for us to run the EM.
WebLogic provide this with the admin console.
Thanks,

I have the same question - and finding no immediate answer I have resorted to deploying a servlet with my webapp that contains the code
http://andersnorgaard.blogspot.com/2005/08/piece-of-java-code-to-walk-jndi-tree.html
Needs some hack to work from the root "" like "name + ("".equals(name) : "" ? "/") + ncp.getName()"

Shared JNDI view among security role

Hi,
We're working on project which needs to expose EJB across different Apps( EAR) in the same OC4J. To my knowledge, in order for those Apps to be able to access the JNDI entry for the exposed EJB, there could be follwing options.
* To enable JNDI entries to be global visiblle. so Bean can be accessible from all other App. This should not be a preferred option since we should not mandate that.
* Whichever app need to access the EJB, it should set the JNDI env to add the credential & JNDI provider URL.of the EJB so the EJB is accessible from those Apps. This adds up the complexity of the configuration for the EJB client.
Would like to see if there's such option to create certain kind of grouping so we can have all the Apps in the same group (e.g. with the same security role) to share the view of JNDI entries so that EJB clients don't need to maintain the credential & provider URL in order to access an EJB across Apps(EAR). Or any other option?
thanks

Calvin,
You can group your client applications together. Here is what you need to do:
1. Deploy your EJB's
2. When you deploy your client applications, under parent application choose the name of your EJB application. This way OC4J knows that the client application is a trusted source (i.e. a child of the parent) and it will not ask you for the credentials. You can then use the JNDI name of the resource that you are looking up.
When you choose the parent application, your server.xml will change and it will get a parent attribute:
<application name="clientapp" path="../applications/clientapp.ear" parent="EJBAppName" auto-start="true" />
Hope this helps.

Specifying JNDI Details for Controls (EJB/JMS) in Workshop

Hello,
I was running into some basic issues in using workshop for building applications. Any help is appreciated !
How do I point Controls (EJB/JMS) to JNDI where the Objects have been bound
In J2EE I will do this :
Context ctx = new InitialContext(ht); // ht has Provider URL etc.
Specifically in Design view of Workshop for (WLI) JMS Control how do you define PROVIDER_URL, SECURITY_PRINCIPAL, etc. My JMS Server is targeted to separate Managed Server that where Workshop Applications are deployed and I do not want to create Foriegn Destinations etc. on Managed Server where Applications get deployed.
For EJB Controls: How do you lookup remote EJBs that get deployed as a part of (EARs) on managed server (different from where Workshop Application and EJB Controls reside)
Basic Question: How do we distribute this "EJB Control" JAR to clients to call these EJBs using controls and specify the JNDI Environment for the control that surfaces the EJB resource deployed remotely?
I cannot import these as modules in an Workshop Application (=> EAR) and generate controls from these as they will get "deployed" in that application and we want only one deployment.
Thanks

Hi there,
In your GUI client you should consdier building a model that represents the data that you want the GUI to display. This model would contain the references to the EJB's that you need to use. If you want to avoid using some kid of model then it really depends on the complexity of your GUI. If your GUI consists of one JFrame then everything can be done inside the main class for the GUI. If you have lots of sub windows then you need to consider where the references will be used. If theyare used in more than one window then you could end up with lots of complex cross references which is why the model would be better in this situation.
JNDI lookups can be expensive and this depends on several factors particularly network latency, if your client is self contained then once you have a reference to a home interface then you may as well keep and use it for any future calls. The key to this is keeping references to home interfaces as instance variables rather than scoping them locally.
There should really be no bottleneck caused by using as single session bean as a Facade to your EJB tier. The Session Facade is a very common pattern and the one that is most espoused by the various authors writing EJB tech books. As far as coupling is concerned this is an ideal situation as your client can then make coarse grained calls to the single facade session bean instead of making lots of smaller fine-grained calls to several session beans. I'd say that this is a good general design.
Hope this helps

JNDI name for TransactionManager?

What is the JNDI name for TransactionManager on Oracle9ias? I thought
it was "java:comp/UserTransaction" but everytime I try to get the
TransactionManager I get a javax.naming.NamingTransaction, root exception is java.lang.NullPointerException. Any help would be appreciated. :-)
TransactionManager trans = null;
String name = null;
try {
InitialContext ctx = new javax.naming.InitialContext();
name = "java:comp/UserTransaction";
trans = (TransactionManager) ctx.lookup( name );
out.println("<p>*** class of TransactionManager is: " + trans);
trans.begin();

Srini,
You mention EJB client -> is the EJB an entity bean? Is it BMT or CMT? If its an entity bean with CMT then you cannot (and should not) be starting the transactions. If however this is BMT then you can use a Sesssion Bean to start and commit the transaction.
I have a feeling that you are using a remote client to access the EJB and then would like to start and commit a transaction. I would like to point out that this kind of transaction demarcation is not supported in OC4J. Here is quote from the OC4J documentation:
"Client-side transaction demarcation is not supported in the application client container: OC4J does not support client-side transaction demarcation. This form of transaction demarcation is not required by the J2EE specification, and is not recommended for performance and latency reasons."
I would recommend that you start using SLSB instead of remote clients.
Hope this helps.

Ios 5 Update New Features says that iCal now has a week view for iPhone but after updating last weekend, I don't see any week view--just List, Day and Month..How do I get the week view?

ios 5 Update New Features says that calendar now has a week view but after updating my iPhone 4 last weekend, I don't see any week view for iCal--just List, Day and Month as in the past. Is the weekly view available for iCal and if so, how do I access it?

HT201412 I cannot open the month of March 2013 in my iPad3 calendar. I can however see it in the year view for 2013 and I can view the daily and weekly calendars for March 2013. Any ideas what has gone wrong ? Thanks

I have a new iPad3 and have found I cannot open the month of March 2013 when I tap on it. All other months open OK ! I can see March 2013 in the yearly view and I can open the individual days, and weeks, of March 2013 but I cannot see the whole month in the monthly view. When I try to open the monthly view for March 2013 it returns me to the start screen which shows all the apps etc and closes the Calendar app. Any guidance of what is going wrong and how it can be corrected. Thanks !

Don't worry we have to start somewhere. Feel free to post your questions here, we learn from each other.

Create a Maintenance view for table T500P

Hi Experts,
We have a requirement where customer want an additional field in table T500P and for the same a custom maintenanve view has to be created.Moreover, If there is any update insert or change in the ZView/Ztable the same should be reflected in standard table T500P.
Steps already taken :-
We have created a ztable (copy of T500P ) and add the required custom field to it.
We have also copied the view i.e V_T500P to our custom view and also use base table as T500P .
We also create a foreign key for PERSA in Ztable and use T500P as check table for that with cardinality 1:1.
To update the MOLGA & BUKRS field data in ztable we have set both the field as a primary key & create a foreign key with check table T500L & T001 & cardianality as 1:CN for key fields.
In custom maintenance view we have set the realtionship of ztable t500l & t001 with the base table T500P.
Now, if we are trying to maintain the view only T500P table is getting updated and Ztable is updated with only PERSA value.
Please provide some directions for the resolution of this issue.
Thanks,
Pooja Goel.

Scheduler007 --
The view you selected by clicking File > Options > Project View is the default view for every new project you create from a blank project template. This is a global option, so setting it from the checked out Enterprise Global file serves no purpose.
When you select a view as your default view, you will see that view applied to the blank project that is opened when you launch Microsoft Project 2010, and you will see it applied if you create new blank projects. If you create enterprise templates for
people to use in your organization, you should simply apply the view to the template that you want as the default so that users will see this view immediately when they create a new project from the template. In addition, if you apply a view to an open
project, close and check in the project, and then reopen the project, you will see the last view applied in that project (as Guillaume correctly points out).
Beyond this, there is no method possible for the Project Server administrator to specify a default view for the Microsoft Project application used by the project managers in your organization. This is an option each PM must set. Hope this helps.

[ADF Help] How to create a view for multiple tables

Hi,
I am using Jdeveloper 11G and ADF framework, and trying to create a view to update multiple tables.
ex:
Table A has these fields: ID, Name
Table B has these fields: ID, Address
A.ID and B.ID are primary keys.
B.ID has FK relationship with A.ID
(basically, these tables have one-to-one relation)
I want to create a view object, which contains these fields: B.ID (or A.ID), A.Name, B.Address.
So I can execute C,R,U,D for both tables.
I create these tables in DB, and create entity objects for these tables.
So there are 2 entity objects and 1 association.
Then I create a view object based on B and add fields of A into the view:
If the association is not a "Composition Association",
when I run the model ("Oracle Business Component Browser") and try to insert new data, fields of A can't edit.
If the association is a "Composition Association", and click the insert button, I will get
"oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity"
If I create a view object based on A and add filed of B into the view:
When I run the model and try to insert new data, fields of B can't edit, no matter the association is or is not a composition association.
So... how can I create a view for multiple tables correctly?
Thanks for any advices!
Here are some pictures about my problem, if there is any unclear point, please let me know.

Hi Branislav,
Thanks, but the result is same ....
In the step 2 of creating view object, I can select entity objects to be added in to the view.
If I select A first, and then select B (the "Source Usage" of B is A), then finishing the wizards.
When I try to create a new record in the view, I can't edit any properties of B (those files are disabled).
If I select B first, and then select A in crating view object, the result is similar ...
Thanks for any further suggestion.

Do I need to create a view for this?

Hi Ihave got 2 tables emp and project
In emp tabe:
emp_no
family name
given name
In porgect table:
emp_no
status(assigned,unassigned)
start_date
end_date
emp_no Family_name given_name
1 Smith John
In project table same employee can have many assigement eg
emp_no status start_date end_date
1 assigned 01-may-08 01-july-08
1 assigned 01-sep-08 01-july-09
1 unassigned 01-july-09 01-oct-09
In the form:
there are 2 querable fields "project ends between field1(date) and field2(date)" which is used to
retrive records which have end date between field1 and field2.
The following fields are needed to get from database:
emp.family_name emp.given_name project.start_date project.end_date No.of time assigned
Requirements:
1. project.start_date and project.end_date must be the latest project_end_date for the same emp
so in the above sample date
2. No. of time assigned is a count of total of number records which have status='assign'
So for the given sample data the record expected after query would be(field1=01-jun-08 field2=02-july-09)
emp.family_name emp.given_name project.start_date project.end_date No.of time assigned
Smith John 01-sep-08 01-july-09 2
What is the best approach to get:
1 The lastest project(latest end_date) for the emp
2. get No.of time assigned.
Do I need to create a view for this? If yes, any sample sql code this this?
Thanks for your help

Hi W1zard,
Thanks for your reply. Could you clarify the following points for me:
1.) you could create a master block basing on your emp table and a detail block basing on your project table with the relation over emp_no. set the default_where clause of your detail block programmatically using
set_block_property('project', default_where, 'status = ''assigned'' and <your_date_criteria>');
Q1: where I pit this code? in pre-query trigger in detail block?
2.) Of course you could create a view to join both of your tables if you don't want to use master detail blocks; Also do the join over emp_no
create or replace force view v_emp as
select emp.family_name, emp.given_name, project.start_date, project.end_date
from emp, project
where emp.emp_no = project.emp_no
Q2 As I mentioned before, there are multipal entries for the same emp in project table and we only need the maching record from project table which has latest end_date. So I think I need something like
max(project.end_date) somewhere in create view to make sure only one record for one employee.
Also is there possible to include the no. of assigned field(select count(*) from project where status='assigned' and emp=emp_no) into the view as well?
Q3 All the fields mentioned above are diaplay-only. So Can I create a control block which has all the fields from emp and project. Then populate them with my sql. The question is
where I put this customerised sql so when user click excute query. My sql will run and display one the form?
REally appreciated your help!

Views for list web parts. Is there a way to allow users to change the view for a list web part without being redirected?

Hi,
I added a list view web part into a SharePoint 2013 page and it is working as expected, except for one thing.
I have enabled the option for the user to change the view for the web part. However when the user changes it, the user is redirected away from the page containing the web part, to the URL of the list itself.
Is there a way to circumvent this issue so when the user selects a different view it updates the listing in the web part itself, rather than the user being redirected?
Thanks in advance for the help.
Regards,
P.

Hi,
Please understand that one page can only display one view. You could find it out by observing the Address in browser when switching among different views for a list.
If you would like to change the view of a list web part, you could go to web part propertites > Select view and configure it.
In addition, here is a thread with similar requirement that might help:

:: NWA does not show table view for monitoring reports ::

Hi,
We are facing an issue in one of our portal system.
I click on Portal index page, then I go to Net weaver Administrator --> Monitoring --> Java system reports.
Here I get the resource utilization graphs.
The graphs show proper values however when I click on table view it does not show any value or table at all.
Then I click on Settings button, and click on Persistent radio button.
It asks to enter the number of days for which the the data should be stored.
I gave it as 2 days and click on Apply button.
It shows a message saying "changes would be effective after restarting monitoring service".
However when I go there i.e. NWA --> Administration --> Applications
I get below services
cafruntimemonitoring~ear
com.sap.ip.bi.sdk.monitoring
tclmwebadminmonitoravail~wd
tclmwebadminmonitorcomplib~wd
tclmwebadminmonitorprovider_ear
tclmwebadminmonitorstate~wd
tclmwebadminoverviewmonitoring~wd
tcmonitoringsysteminfo
Would you kindly suggest which service from above list should be restarted ?
Thank you, Regards,

I think what is being asked is "How do I expose a database view as a schema table in Configuration Manager?"
This is accomplished by creating a database view within the WCC database schema (and with the WCC schema user as the view owner). The view then will appear as a table in the "table" tab in Configuration Manager.
One caveat in 11g is that the user created by RCU does not have any privileges to read/create views in its own schema. You may need to grant privileges to views for the WCC schema user before this will work.

Changing the default view for Line Items in an Auction.

Hello All,
We have a version 5 client who is asking for us to change the default view for line items in an auction.
Currently, if you have an auction setup, and you go to the Line Items tab, the default view is the "Basic View". The client would like to change the Default from "basic view" to "price view".
Is there a way to change this default in the system? Can this be configured using query groups? Any information would be helpful.

Hi wood cloud,
This is not possible, bcz there is no VLV for that drop down and we cant set it to the price view.
Thanks,

Changing the default associated view for a related entity

A question from a peer:
Hey there
Do you know how in CRM 2015 to change the default associated view for a related entity?
Say you are in an Account and from the menu open the opportunities for that account.
That new pop up window states “Opportunity Associated View” I want to change that to “My Custom View”
I thought we covered this in class years back but cannot remember

There are a few ways to get what you want, the easiest being
Create a document as you want it for a particular site, save it is junk.php or similar and create a new file by saving as this as the proper document name such as index.php
Use the Dreamweaver template system, i.e. create a template with a .dwt.php extension like template.dwt.php and use that to create new pages.
There are other ways like creating your own php template system. But you can put that in the too hard basket.
