CGS4854 Assignment 5

Due Thursday, 4/2 at 1pm.

If you had any errors in Homework 4, then fix them, so that you don't lose points twice for the same mistake.

Post Controller

Create a new package for this assignment in your username web app.

• Do not change the files that were used for assignment 4.
  • Assignment 4 should still be accessible from the web app.
  • You may copy files from assignment 4 into this new package.
  • You may import files from assignment 4, if they are unchanged.
• Modify the application so that it implements the Post Controller from Chapter 5 with required validation. Review the steps in Tutorial 5.
  • Add all the necessary files to the shared package.
  • Note that HellperBaseCh5 should be placed in the shared package.
  • Add all the necessary JAR files to the Libraries folder.
• Bean
  • Place the bean in the same package as the controller.
  • The bean should implement required validation.
    • Validate that one of the numeric fields is in a specific range of numbers. Do not include 0 in the range. There are additional annotations that can be used with numeric properties.
      • Remove any default validation for this field.
      • @Min(value=100). Do not use the Hibernate annotation, use mine. Add the following files to the shared package: Min.java, MinValidator.java.
      • @Max(value=200). Do not use the Hibernate annotation, use mine. Add the following files to the shared package: Max.java, MaxValidator.java.
      • @Range(min=100,max=200). This is a built-in annotation for Hibernate: Built-in Annotations for Hibernate.
      • Each of these needs an import statement:
        import shared.Min;
import shared.Max;
import org.hibernate.validator.Range;
    • Use the Pattern annotation to validate that one of the string properties only contains one of several words.
      • Choose at least three words.
      • The match should not be case sensitive.
    • For each field that is to be validated, display information in the web page that indicates the correct format of the data to be entered.
• Controller Helper
  • Use a unique name, other than "helper", to save the controller helper in the session.
  • Rename the getData method.
  • Modify jspLocation so that it returns the correct path for JSPs.
• JSPs
  • There should be no hidden fields in any of the JSPs.
  • The JSPs should be in a hidden directory, but not in the same directory as the controller. Move the JSPs to an appropriate subdirectory of WEB-INF (not under classes).
  • Modify all the EL statements so that they refer to the new name that you used to store the helper in the session.
  • Modify all the EL statements so that they refer to the new name that you used instead of getData.
• Be sure there is a hypertext link in the index.jsp page to the controller. Use a relative link.
• The web app must use the secure web.xml file and should only allow you and me to access your application: Edit tomcat users
• Be sure to modify the project so that the .java files are placed in the WAR file: Configuring WAR File
• After the app is running in NetBeans, upload it and run it on ocelot: Uploading a WAR file

Submitting the Assignment

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.
• Use the manager to stop your web application and then start it again. This will force it to reread the web.xml file so that the logger can be initialized.
• 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.

• Please delete your old ZIP file that you used to submit homework.
  rm username.zip
  Replacing username with your user name.
• Please zip the following. Issue a separate ZIP command for each. All the files will be added to the same ZIP file.
  • Please use the following command to compress your cgs4854/webapps/username folder.
    zip -r username ~/cgs4854/webapps/username -x \*.jar \*.zip \*.war
    Replacing username with your user name. This will create a file named username.zip. It contains the username 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.
