Overview

As mentioned in Part1,it is about references between mapping programs. Part 1 (References between Mapping Programs-Part1) talks about how to trigger java class from message mapping and Java mapping.

Part2:covers last two topics, means how to trigger java class from xslt mapping and how to trigger xslt mapping from other xslt mapping.

Part2

3. XSLT mapping can use (cross reference) other java class of an archive.

4. XSLT mapping can use (cross reference) other xslt mapping with help of "import".

Note:Same source message type and target message types are used as in the part1.

3. XSLT mapping can use (cross reference) other java class of an archive.

XSLT mapping can call a java method of other java class which is archived in the same software component.

In the given example xslt program calls "grade" method to find the grade of a students as providing their marks as input to the method.

Steps:

a) Create java class and import into XI (import archive).

b) Create xslt mapping program to trigger java method and import into xi(import archive)

Xslt and Java class (archive) 

//Java class which can be called from xslt mapping program:

*

package prasad.map

public class XSLTTesting {

public static String grade(String a,String b,String c)

{

int e = Integer.parseInt(a);

int f = Integer.parseInt(b);

int g = Integer.parseInt(c);

float average = (efg)/3;

if(average>=90)

return "Grade A";

else if(average>=80)

return "Grade B";

else if(average>=70)

return "Grade C";

else if(average>=60)

return "First Class";

else if(average>=50)

return "Pass";

else

return "fail";

}

XSLT mapping can use (cross reference) other xslt mapping with help of "import".

Description: It talks about how to call one xslt program into another xslt program. In this example there are two xslt mappings. 

Steps:

*1)"xslt_to_xslt_called.xsl" which implements complete mapping and it is triggered by main xslt mapping. 2)" xslt_to_xslt_main.xsl" which just calls the first xsl program. a) Create xslt mapping (xslt_to_xslt_called.xsl) which should be called from main xslt mapping and deploy it into xi (import archive). b) Create main xslt mapping (xslt_to_xslt_main.xsl) to trigger other xslt and deploy into xi (import archive) XSL Codes
