Setting Smart Aliases

Configuring Smart Aliases

1. In SAP NetWeaver Developer Studio, choose  Window  Preferences 

2. In the dialog box that appears, on the left hand side, expand the Rules Composer node, the Smart Aliases node.

   You should see the Java and XSD options under the Smart Aliases node.

To use Java annotations for aliases

1. Choose the Java option.

2. In the screen that appears, select the Use Java Annotations for Aliases checkbox.

3. Enter the class name and alias name method in the relevant fields.

   Example

   Annotation Class Name = com.sap.annotation.MyAlias

   Annotation Alias Name Method = aliasName for the following example.

   Annotation Class:

   package ;

   @RetentionPolicy(RetentionPolicy.RUNTIME)

   public @interface {

   String aliasName();

   Sample Class:

   package com.sap.sample;

   @ ( ="Employee Object")

   public class Employee {

   private String name;

   @ ( ="Employee's Global Id")

   public String GLOBAL_ID = "I047312";

   @ ( ="New Employee")

   public Employee(){

   }

   @ ( ="Employee's Name")

   public String getName() {

   return name;

   }

   }

4. Select the Use Pattern checkbox and enter valid patterns in the text box.

   Note

   Examples of few valid patterns:

   • {MemberName} of {ClassName}

   • A {ClassName} has a {PropertyName}

   • {ClassName}.{MemberName} (This is similar to default aliases)

   Keywords

   {PropertyName} is a place holder for properties. The property names are derived from the member names of the class.

   {ClassName} is a place holder for Java class name or Definition name.

   {MemberName} is a place holder for properties. The property names are derived from the member names of the class.

To use XSD annotations as aliases

1. Select the Use XSD Annotations as Aliases checkbox

2. In the Read XSD Annotation as section. do one of the following:

   • Choose Attribute and enter the attribute name in the relevant field.

     Example

     Attribute Name = aliasname for the following sample schema:

     http://www.w3.org/2001/XMLSchema

     xmlns:ns4="http://demo.sap.com/samples"

     xmlns="xmlsc.xsd" targetNamespace="xmlsc.xsd"

     elementFormDefault="qualified" attributeFormDefault="qualified">

     <xsd:element name="students" type="studentsType"/>

     <xsd:complexType name="studentsType"/>

     <xsd:sequence maxOccurs="unbounded">

     <xsd:element name="student" type="studentType" />

     </xsd:sequence>

     </xsd:complexType>

     <xsd:complexType name="studentType">

     <xsd:sequence>

     <xsd:element name="rollNo" type="xsd string">

     <xsd:annotation>

     <xsd:appinfo ns4: =Student Roll Number />

     </xsd:annotation>

     </xsd:element>

     </xsd:sequence>

     </xsd:complexType>

     </xsd:schema>

   • Choose Element with "source" URI and enter a valid source URI in the relevant field.

     Example

     Source URI = com.sap.brms.alias for the following sample schema:

     http://www.w3.org/2001/XMLSchema

     xmlns:ns4="http://demo.sap.com/samples"

     xmlns="xmlsc.xsd" targetNamespace="xmlsc.xsd"

     elementFormDefault="qualified" attributeFormDefault="qualified">

     <xsd:element name="students" type="studentsType"/>

     <xsd:complexType name="studentsType">

     <xsd:sequence maxOccurs="unbounded">

     <xsd:element name="student" type="studentType"/>

     </xsd:sequence>

     </xsd:complexType>

     <xsd:complexType name="studentType">

     <xsd:sequence>

     <xsd:element name="rollNo" type="xsd string">

     <xsd:annotation>

     <xsd:appinfo source=" ">

     Student Roll Number

     </xsd:appinfo>

     </xsd:annotation>

     </xsd:element>

     </xsd:sequence>

     </xsd:complexType>

     </xsd:schema>

   • Choose Element without "source" URI .

     Example

     Sample XSD Element with annotation defined as an attribute without source URI:

     <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns4="http://demo.sap.com/samples" xmlns="xmlsc.xsd" targetNamespace="xmlsc.xsd" elementFormDefault="qualified" attributeFormDefault="qualified">

     <xsd:element name="students" type="studentsType" />

     <xsd:complexType name="studentsType">

     <xsd:sequence maxOccurs="unbounded">

     <xsd:element name="student" type="studentType" />

     </xsd:sequence>

     </xsd:complexType>

     <xsd:complexType name="studentType">

     <xsd:sequence>

     <xsd:annotation>

     <xsd: >

     Student Roll Number

     </xsd: >

     </xsd:annotation>

     </xsd:element>

     </xsd:sequence>

     </xsd:complexType>

     </xsd:schema>
