Chapter 6 - Code Snippets

Add Data Validation Code: Phase I - Add a Validation Check on the Salary Column Using Java
p. 183-184

To add the error handling class, locate the import statments and add

   import oracle.jbo.JboException;

Locate setSal() method and modify it to look like the following code:

/**
  * Sets <code>value</code> as the attribute value for Sal
  */
public void setSal(Number value) {
  if (value.floatValue() < 500){
  throw new JboException("Salary below minimum");
 }
 setAttributeInternal(SAL, value);
}

Add Data Validation Code: Phase II - Create Attribute Validation at the Row Level
p. 184-185

To add an error handling class, locate the import statements and add the
following code:

   import oracle.jbo.JboException;

Add the following code just above the getGrade() method. You may implement either block of code.

public void validateEntity() {
   //Generated call
   super.validateEntity();

   //Custom validation is added here using special Jbo Boolean checks
   //Rule: Losal is greater than Hisal - throw exception
   if (this.getLosal().compareTo(this.getHisal()) > 0 ){
      throw new JboException("Losal greater than Hisal.");
   }
}

or

public void validateEntity() {
   //Generated call
   super.validateEntity();

   //Custom validation is added here using type conversion
   //Rule: Losal is greater than Hisal - throw exception
   if (this.getLosal().shortValue() > this.getHisal().shortValue()){
       throw new JboException("Losal greater than Hisal.");
   }
}
