CGS4854 Tutorial 5

Due Thursday, 3/26 at 1 pm.

If you did not do a previous Tutorial, then create a web application named book 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 book web application. It must work exactly like the example from Chapter 5 of the book. It uses many of the files from the Required Validation Controller.

• Follow the instructions for the Required Validation and Post applications on the book's web site.
• Add a hypertext link in index.jsp to the Post controller.
  • Be sure that the index.jsp uses the strict DOCTYPE.
  • Use a relative link from the current location to the controller. Use the url-pattern from the web.xml, but omit the leading /.
  • All the previous Tutorials should also have links from this page. All of them should still work.

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. 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.

To hand in the assignment, zip the following directories into one ZIP file and upload it.

• First, delete the current book.zip file
  rm book.zip
• Next, please use the following command to compress your cgs4854/webapps/book folder.
  zip -r book ~/cgs4854/webapps/book -x \*.jar \*.zip \*.war \*.nfs\*
  Replacing book with the name of your book web app, if you used a different name. This will create a file named book.zip. It contains the book web application.
• 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.

Be sure that all your files and subdirectories are included in the zip file.
After uploading, do not modify your files on ocelot until after your assignment has been graded.
