JavaPOS Installation not compatible with Windows 10, therefore I need to write my own jpos.xml file. Which files to include? -

-

ive been researching ins , outs of javapos, jcl, jdk, paths , classpaths while trying figure out how can print line on epson tm-t20 receipt printer using javapos. since javapos installation disc (that came printer) not install correctly on windows 10 (thinks installing on linux), need create own jpos.xml file. needs contain device entries printer. (i have tried fresh javapos adk download epson , older version without success).

this setup far....

  1. i have extracted latest jcl. instead of setting classpath jcl binary files (jar files), ive placed them in java ext directory.
  2. i extracted java "src.zip" located in jdk1.8.0_74 jdk1.8.0_74 directory "src".
  3. i have placed "jpos" folder containing jpos source files "src" folder, can import them test application.
  4. i have studied other jpos.xml (including postest/2 & starmicronics eg.) idea of entries mine needs contain.
  5. ive placed jpos.xml in java "src" folder.

here jpos.xml....

<?xml version="1.0" encoding="utf-8"?> <!doctype jposentries public "-//javapos//dtd//en"  "jpos/res/jcl.dtd">  <jposentries> <!--saved javapos jpos.config/loader (jcl) version 2.3.0-rc3 on 6/03/16 1:20 pm-->  <jposentry logicalname="tm-t20">  <creation factoryclass="jpos.loader.jposserviceinstancefactory" serviceclass="jpos.services.posprinterservice114"/> <vendor name="seiko epson" url="http://www.epson.com"/>  <jpos category="posprinter" version="1.14"/>  <product description="epson thermal receipt printer tm-t20" name="tm-t20" url="http://www.epson.com"/>   <!--other non javapos required property (mostly vendor properties , bus specific properties i.e. rs232 )-->  <prop name="devicebus" type="string" value="usb"/> <prop name="portname" type="string" value="esdprt001"/>  <prop name="model" type="string" value="tm-t20"/> </jposentry>    </jposentries>

here test application...

the error message is.... "could not connect service logicalname = tm-t20: exception.message = jpos.loader.jpos.serviceinstancefactory.init()"

i'm guessing jpos.xml file entries incorrect, factoryclass &/or serviceclass. please can me. perhaps has jpos.xml file created tm-t20 , wouldn't mind sharing.

i'm using react-router first time , don't know how think in yet. here's how i'm loading components in nested routes. entry point .js reactdom.render( <router history={hashhistory} > <route path="/" component={app}> <route path="models" component={content}> </route> </router>, document.getelementbyid('app') ); app.js render: function() { return ( <div> <header /> {this.props.children} </div> ); } so child of app content component sent in. i'm using flux , app.js has state , listens changes, don't know how pass state down this.props.children. before using react-router app.js defines children explicitly, passing state natural don't see how now. using couple of react helper methods can add state, props , whatever else this.props.children render: function() { var children = react.ch...
