I have been trying to build a custom code library that could be reused across our numerious scripts in out environment. We have come accross a good amount of logic that can be located in a single resource, if possible. I am mainly a .Net developer and fairly new to Java coding.

I have downloaded new JDBC Drivers for connecting to SQL Server "com.microsoft.jdbc.sqlserver.SQLServerDriver" and got everything to work. From this experience I was hoping I could achieve my goals by compiling my own library and accessing it in Script Tasks.

I have created a new test class and compiled it into a JAR. I then copied the JAR into the JRE\Bin folder. I have also modified the ClassPath System Variable value to include this location.

Any help would be great thanks!

Test Class is as follows
==========================
Code:

package com.horizonhobby.logility;
/* Imports */
import com.hitek.engine.mods.script.*;
public class Automize
{
   public Automize(){}
   
   public void writeLogInfo(String Msg){
      System.out.println("Started");
      Script.run("AutoTest");
      System.out.println("Finieshed");
   }
}

==========================

Here is a secon Test class that I added to the JAR to see if there would be compile / run time errors but everything works, except for nothing output to the Activilty Log
==========================
Code:

import com.horizonhobby.logility.*;
public class TestAutomize {
   public static void main(String[] args) {
      System.out.println("Void Main First");
      Automize myAutomize = new Automize();
      myAutomize.writeLogInfo("Brads Test");
   }
}

==========================

Here's the Sql JDBC Example
==========================
Code:

import com.hitek.engine.mods.script.Script;
import com.microsoft.jdbc.sqlserver.SQLServerDriver;
import java.io.*;
import java.sql.*;
import java.text.*;
import java.util.*;

String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String url = "jdbc:microsoft:sqlserver://ServerName:Port#;DatabaseName=DBName;";
String username = "Username";
String password = "Password";
Connection connection = null;
Class.forName(driverName);
Driver d = (Driver)Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
connection = DriverManager.getConnection(url, username, password);
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery("SELECT Top 10 * FROM Steps");
while (rs.next()) {
   s = rs.getString("Name");
   Script.act("Step Name: " + s);
   Script.out("Step Name: " + s);
}

1) To output to output log, use:
Script.out("test");

2) All jars in the main Automize folder are automatically added to classpath when launching the engine from user interface.

3) The other option is to launch the user interface and engine using batch files. Sample Automize.bat file is located in the main install folder. simply drop your .jar into Automize7 main folder and add the jar name to the launch code in the batch file.

I have tried dropping my JAR into the following and have not had any luck.

    C:\Program Files\Automize7
    C:\Program Files\Automize7\jre
    C:\Program Files\Automize7\jre\bin


To get the custome Sql Server JDBC Drivers to work I had to drop the three JAR files into the "C:\Program Files\Automize7\jre\bin" folder. Before that I was getting an invalid Classpath error.

Due to the fact that I am a .Net developer not a Java developer I am still trying to pick this up and it might be that fact that I am new to the errors that I am recieving.

Any help would be great.

Thanks

Here's my test Script trying to call my test class in my JAR.

Automize myA = new Automize();
myA.writeLogInfo("Brads Test");

1) hitek7.jar also has an Automize class. rename the class and see if the error goes away..
2) what is the hierachy of the Automize class in your jar?
