RemoteOperationException: ERROR: Invalid username and/or password Hi Do you face this problem? When you try to start up the oracle database using EM,you are prompted to enter windows username and password.And you are sure that the username and password are correct, however this error occurs. This is the solution: Step1 : Goto control panel -> Administrative Tool -> Local Security Settings.        Local Policies -> User Rights Assignment -> double click on 'Log on as a batch job' Step 2 : Add the user here which you are trying accessing the OEM and click apply and OK. Step3 : Follow the step 2 for adding user to 'Log on as a service'. Step4 : Now try to log on to OEM.           You will get the following screen if db is down. Hope this could help you to resolve the error.

In this discussion , I will show how to achieve this task within both the ViewController and Model project. 1- How to achieve this in the ViewController Project. The following method accepts a String parameter which is the KEY and return the text for this key in the resource bundle. String resourceBundle is variable represents the class name of the resource bundle file. In order to now the resource bundle for the project , Just go to the project property,Resource Bundle /** * added by tarek fathy  * oct 02 2012  * use this method to return a value from the ViewControllerBundle file  * just pass the key  * @param identifier  * @return String  * this method will work only if the rec...

To ensure that the credentials that you supply in the database connections for your ADF Application are deployed and include the password, add  -Djps.app.credential.overwrite.allowed=true  to the JAVA_PROPERTIES entry in the FMW_HOME /user_projects/domains/ yourdomain /bin/setDomainEnv.sh file (or setDomainEnv.cmd if you are on Windows), and restart the server using FMW_HOME /user_projects/domains/ yourdomain /bin/startWebLogic.sh. This is what you need to do if you have deployed an ADF application to your server but are seeing the following errors when the application is accessed: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection. at oracle.jbo.server.ConnectionPool.createConnection(ConnectionPool.java:253) at oracle.jbo.server.ConnectionPool.instantiateResource(ConnectionPool.java:168) at oracle.jbo.pool.ResourcePool.createResource(ResourcePool.java:546) at oracle.jbo.pool.ResourcePool.useResource(ResourcePool.java:327) at oracle.jbo.server.Conn...

Some times you  want to check if the data has been modified by the user or not. We can remember how easily we make this in forms builder using ":System.record_status" or :System.block_status" or :System.form_status". But the ADF world is somehow different. Just write this code

Instead of looping throw the iterator to get the value from the index, You can simply set the property "valuePassThrough" = true in the list
