The cause might be with missing classes in your project path. In my case, I am trying to make web service call through java class and I got the above issue. To fix the issue, I have added wseeclient.jar to the project class path. I am using IDE JDeveloper to run my main java class. And this jar will be present in below path in my case. C:\Oracle\Middleware\wlserver_10.3\server\lib 

This blog will explain how to send email from java code. In order to send email from java code, we need to set properties of mail server and protocol. In my example I have set the authentication to false. So no authentication required before sending the email. Below is the working java code to send email. import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class SendEmail {     public SendEmail() {         super();     }     public static void main(String[] args) {         SendEmail sendEmail = new SendEmail();         //here you can set array size more to send mail to more users.       ...

Many might have faced this situation while fixing bugs in ADF application. There will be one main application and it uses task flows or classes from different shared libraries. For example there is an issue in one shared library, to fix that we just run that particular project/application and try to fix the issue in that shared library project. But if the application is ADF security enabled then it is little difficult to perform exact test cases what we do when it is integrated with main application after fix. Because all the security settings are in main application jazn-data.xml file. We can disable security for a while and test the application. But it is not a good idea. Because by disabling security we are not doing full testing at all. So how to overcome this situation?   There is a sample way. We can create some dummy test users and test roles in development weblogic server. These test roles names should be same as the one we defined in jazn-data.xml in...
