We have introduced CholaMeetings.com for all our live classes conducted through adf training at https://www.cholanacademy.com/.
While live classes are frequently taken through different tools, now we had switched to Chola Meetings for better control and features.
Based on the popular request from our learners, below is the self paced course bundle offering for you to save money as well as time. It is like learning yesterday, today and tomorrow of Oracle Technologies for an EBS Technical Consultant.
The courses included are OAF + ADF Beginners + Oracle Fusion Tech Cloud and the price is $299
On our 10th Year of ADFTraining.com, we would like to thank all our supporters and learners to help us sail through all these years. We started this website when US was under peak recession in 2008 to help people to learn new technologies for free.
In 2016, we went live with a large scale conversion of a College system from .net and oracle forms to Oracle ADF application with dashboard integration to OBIEE in Muscat with Ministry of Manpower, Oman. The major challenge we faced is the performance issues when there were around 6000 concurrent users and the expectation was to handle the 13000 concurrent users. Read more to view how we solved it...
I am excited to hear the news of new JDeveloper for Oracle ADF...You heard it right !!!..
Oracle JDeveloper 19.1.0.0.0 is coming and it has new UI features for ADF which can be Oracle JET integration..
In one of our ADF Training batches, we had noticed an issue related to ADF Security not working on the authorization part when enabled on a Oracle ADF REST API.The authentication part was working fine, but the authorization was failing on ADF 12.2.1.2.0
After scratching the head for few hours, the solution has been arrived at...Thanks to Google Search and Andrejus Post.
import oracle.jbo.VariableValueManager;
import oracle.jbo.ViewCriteria;
import oracle.jbo.server.ApplicationModuleImpl;
import oracle.jbo.server.ViewLinkImpl;
import oracle.jbo.server.ViewObjectImpl;
public void applyVCforGlobalSearchProjects(String searchCriteria){
ViewObjectImpl vo;
vo = this.getProjects();
ViewCriteria vc = vo.getViewCriteria("HrProjectsVOCriteria");
vc.resetCriteria();
VariableValueManager vvm = vc.ensureVariableManager();
vvm.setVariableValue("p_search_criteria", searchCriteria);
vo.applyViewCriteria(vc,true);
vo.executeQuery();
}
Below are the bugs which we found while working with JDeveloper 12.2.1.3.0 and their corresponding work arounds
In JDeveloper 12c there is a feature called add custom operator in view criteria, default operators are commonly using in many places, in some cases we need to have additional operators.
In sql developer we can use In clause parameter directly which jdeveloper doesn’t have by default.
Recently I had migrated the MAF app for one of our client to IOS 9.2 using MAF 2.2.1 and found the issue like below.
The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
Below are the steps to fix the issue
The main complaint against the JDeveloper is that it is very slow..Yes, of course you can increase the heapsize and use 64 bit jdk to speed up the slow jdeveloper.
But still the design view for the page and page fragment is very slow.Sometimes it hangs and creates lot of frustration among the ADF developers.Here is the way you can set the default view as source view for the page and page fragment.
The navigations were slightly confusing in 12.1.3 JDeveloper..Here is the screenshot for the same.
I had a requirement to move a bunch of personalization from one instance to another in my current project.I did lot of googling as well as raised an SR with oracle to find the best way to move the personalizations from one instance to another..And then I gave up on it for sometime and later while researching on a different topic I found out the best way to move adf saved queries and user personalization.
It is as simple as export from the source instance and import into the destination MDS using the EM Console.Let me show the steps here..
I got really excited to hear the news that Oracle JDeveloper 12c released finally.I tried to install the 12c jdeveloper to get my hands dirty but couldn’t even install it :(.
On windows, installer quit abruptly without any error message and on MAC, what the heck happened I don’t even know.Here is the solution to install them successfully on MAC and Windows.
In the last article, I had taken you through the steps required to source control your Oracle ADF apps with the help of code.adfapps.com repository and subversion.Let me show you how to checkout an existing oracle adf project from the code.adfapps.com subversion repository.
High level steps:
1) Connect to Subversion repository using the credentials
2) Open up the Versioning Navigator in the JDeveloper
3) Open up your repository and go to (Trunk or Branches or Tags)
4) Checkout the appropriate project folder by right click on the folder and say checkout
Below are the steps in detail:
In the last article, we had seen how to deploy Oracle ADF app to the java cloud from jdeveloper.In this article, let us create some objects in model project with the Department and Employees table from oracle XE database to deploy those tables to the database cloud.Once you migrate the required tables from the XE database to Database cloud, we can deploy our ADF app to javacloud.
Here are the high level steps.
1) Develop your ADF app locally connecting to the Oracle XE database
2) Migrate the referred tables to the associated database cloud
3) Modify the Root AM’s datasource to database.
4) Deploy the ADF app to the Java Cloud.
It is a very rare sight that a project team with more than 2 developers doesn’t have any source control in place while working on an Oracle ADF development project.If you don’t have source control for Oracle ADF development, then your project needs a better project manager and architect :).
I had created a small project to demonstrate source control with Oracle ADF jdeveloper’s native support for subversion(SVN).We will use the code.adfapps.com for our subversion project hosting.
Below are the high level steps..
1) Create a manual connection to subversion repository from Jdeveloper
2) Click on the Application menu and say version application.
3) Select the repository connection and choose whether to version control to trunk,tags or branch(Put it in Trunk for the first time)
4) That’s it.. We are done with source control..No, there are lot of challenges still.We will cover them one by one in the 5 part series.
For now, let us look at the above steps in detail.
Oracle public cloud simplifies the process of deploying your application and keep it running without much of a headache specially if you don’t have full fledged IT team to maintain the application.You need to register for Oracle Cloud Java Trial account with the below url.
https://cloud.oracle.com/mycloud/f?p=service:java:0:::::
Once the trial activation is done, you will receive username/password to login to identity console(Probably in your junk email :) )
Let us go over the steps in detail.
This is a very interesting issue which totally got me stumped as the application was working perfectly fine in 11.1.1.6 and then migrating the app to 11.1.2.3 resulted in the below error while uploading the file to a blob column.
Cannot create an object of
type:oracle.jbo.domain.BlobDomain from
type:weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB with
value:weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB@114
Solution is as below.
In the last part of this series, I had explained you about how to checkout an Oracle ADF project from subversion and run the page from JDeveloper.In this part, I will explain you how to make changes to the checkout project and commit changes to the subversion repository using the pending changes tab in JDeveloper.
High Level steps:
1) Make a change to the jsf page
2) Open up the pending changes tab
3) Select the changed files and click on commit button
4) Provide a commit message to commit the changes to repository.
Above steps in detail:
This is the feature you must have been used to if you had used forms developer and I missed this with the previous version of jdeveloper, specially during the OAF development days.But here is the relief in the 11g version of JDeveloper.I noticed this option while opening the jdeveloper 11g version 11.1.2.3 and came as a tip in jdeveloper.
Lets see how we can use this option.
