Attach plugin written in Java

If a function can not be made with PHP, it is possible to include a reporting system functions written in Java. The following describes the methodology to attach Test object and its use in the report

Attach Java object to ProReports.

Suppose you have a file test.java with the following content:

public class Test
{
private a int;
private b int;
public Test(Int a, Int b)
{
this.a = a;
this.b = b;
}
public Int Sum()
{
return this.a+this.b;
}
}

After compiling it you get a file test.class. This file should be placed in directory:

<directory of proreports>/webapps-plus/rep/WEB-INF/classes

If the class uses some libraries, they should be placed in the directory:

• Linux i Windows

<directory of proreports>/JRE/<dir of JVM>/lib/ext

• AIX

<directory of proreports>/JRE/<dir of JVM>/jre/lib

• or (for all operating systems) in

<directory of proreports>/webapps-plus/rep/WEB-INF/lib

The use of Java object in Internal report.

To use attached object in Internal report, in any Element of the report in part Expression/Code before Template or Expression/Code after Template please enter the code:

import Test;
$objtst=new Test(2,3);
$V[sum]=$objtst->Sum();

This code create object $objtst and set global variable $V[sum], which can be used anywhere in the report.
