Hi all,

I want to extend NACChannel by adding 2 properties (nii and f25) in it. So my channel config will look like:

<channel class="mobi.xxx.jpos.channel.XXXNACChannel" logger="Q2"

realm="channel" timeout="600000" packager="org.jpos.iso.packager.GenericPackager"

header="6000036549">

</channel>

My class look like:

public class XXXNACChannel extends NACChannel {

String nii;

String field25;

public XXXNACChannel(String nii, String field25) {

super();

this.nii = nii;

this.field25 = field25;

}

public String getNii() {

return nii;

}

public void setNii(String nii) {

this.nii = nii;

}

public String getField25() {

return field25;

}

public void setField25(String field25) {

this.field25 = field25;

}

Then when I start jpos, exception raised:

<warn>

error starting service

<iso-exception>

mobi.softpay.jpos.channel.XXXNACChannel
