CGS4854 Tutorial 5

Due Thursday, 3/31

If you did not do a previous Tutorial, then create a web application named Tutorials in NetBeans. Review the web page that contains instructions on creating a servlet in a NetBeans project: Creating a Project in NetBeans

All previous Tutorials should still be able to be accessed and run from the application.

If you had errors in any of the previous tutorials, fix them, so that you do not lose points again for old mistakes.

Implement the Post Controller in the Tutorials web application. It must work exactly like the example from Chapter 5 of the book. In other words, it must also do required validation.

• Implement the RequiredValidation controller. It must work exactly as it does on the web site. Visit the tutorials page for step-by-step instructions.
• Implement the RequiredPost controller. It must work exactly as it does on the web site. Visit the tutorials page for step-by-step instructions.

Take a look at your log file, you will see that there are messages in it.

• Open the Files tab in NetBeans and navigate to build -> web -> WEB-INF -> logs
• Open the error.log file. It will look something like this.
  

Submitting Homework

Be sure that your NetBeans project is configured so that .java files are added to the WAR file: Adding .java files to a WAR file

Clean and Build your web application. After doing this, navigate to the WAR file in NetBeans and verify that the .java files are included: View WAR File

• Since you are using a log file that is in the web application, you will need to shut down Tomcat before you can do a Clean and Build.
• Open the Services (Runtime in 5.5) folder and open the Servers folder.
• Right-click the Tomcat server and select Stop.
• Now you can do a Clean and Build. 

In the operating system (not in NetBeans) navigate to the dist folder in the NetBeans project.

Deploy the WAR file on ocelot: Deploy a WAR File

• After deploying, open the WEB-INF/logs directory in winscp or on ocelot.
• Change the permission of the error.log file to 606 and restart the web app from your manager. This will allow Tomcat to write to the file.
• Access your application and visit all the pages, then verify that some new messages have been added to the log file.

The WAR file is too big for you to submit to me. To hand in the tutorial, zip the Tutorials web app directory and upload it. If your web app is named something other than Tutorials, then use that name in the zip command.

• Remove the old zip file from the last upload.
  rm username.zip
• Please use the following command to compress your webapps folder.
  zip -r username ~/cgs4854/webapps/Tutorials -x \*.jar \*.zip \*.war \*.jpg \*.png \*.gif 
  Replacing username with your user name. This will create a file named username.zip.
• Check the size of the ZIP file, it should be less than 3 MB. If it is not, then you probably have another ZIP file stored in the ZIP archive. Delete it and re-zip.
• You then have a choice for submitting the file.
  • If you are logged onto ocelot, use my uploading program to upload the file. Enter this command at the command prompt:
    ~downeyt/cs/public/webftp/webftp.pl
  • If you are using winscp, then download the zip file to your computer; then, upload the file to me: Submitting homework on-line via the Web.
• Upload the file as binary.
