Error invoking bsh method:....Error in method invocation: Method createCa( int ) not found in class'cacreator.CaCreator'
<p>I am pretty new to Jmeter tool and I am trying to use my own java class to call a function in BeanShell Pre-Processor.
I have written a Java programme and packaged it into a .jar file and copied it into the /lib/ext folder where the Jmeter is installed.
Here is my java class snippet:</p>

<pre><code>package cacreator;
import java.util.Scanner;

public class CaCreator {

static  String Name = "\"Name\" : 11";
static  String AppName = "\"ApplicationGroup\" : \"qa\"";
static  String caValues = ""; // = "[{";

public static String createCa(int count)
{

    for (int vCount = 1; vCount &lt;= count; vCount++) {
        caValues = caValues.concat( "\n" + "{ \n" + Name + ", \n\"Value\" : \"" + vCount+300 + "\",\n" + AppName + "\n}");
        if(vCount != count)
        {
            caValues = caValues.concat(",");
           // caValues = caValues.concat("\"Name\" : \"Test");
        }
    }
    return caValues;
}
</code></pre>

<p>and the code for BeanShell Pre-Processor:</p>

<pre><code>import cacreator.CaCreator;
CaCreator obj1 = new CaCreator();
int firstParam = Integer.parseInt(bsh.args[0]);
String outPut = obj1.createCa(firstParam);
vars.put("ca", outPut);
</code></pre>

<p>i am getting the following errors:</p>

<pre><code>ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval   Sourced file: inline evaluation of: ``import cacreator.CaCreator; CaCreator obj1 = new CaCreator(); int firstParam = I . . .

</code></pre>

<p>Thanks in advance!</p>
