December 11, 2014 file is missing in android application

While working with an android application in eclipse, some times the file may missed out from the application. This is because the XML files in the app may have errors. So, resolve those errors in the XML files and then clean the project. Now the file will be automatically created.

android.content.ActivityNotFoundException: Unable to find explicit activity class

I am developing an android application. On the home screen, it has a button, on click of this an activity should be displayed. While testing the app, on click of the button, the app is giving the below error and the app got terminated.

E/AndroidRuntime(Number): java.lang.RuntimeException: Unable to resume activity {app package}: android.content.ActivityNotFoundException: Unable to find explicit activity class {activity class}; have you declared this activity in your AndroidManifest.xml?

The solution for this is,

Every activity created in android application should be configured in AndroidManifest.xml of the app. To do so, open AndroidManifest.xml and goto Application tab. Under Application Nodes, add all the activities.

Error: oracle.jdevimpl.deploy.common.Jsr88RemoteDeployer

I am developing a REST web service. While deploying the web service to the application server, I got the below error.

Remote deployment failed (oracle.jdevimpl.deploy.common.Jsr88RemoteDeployer)

The error occurred because my web service has two methods with the same path name. After changing the path names, the issue got resolved and the web service was deployed successfully to the server.
