and its my original beanimport java.util.Map;

import javax.faces.context.ExternalContext;

import javax.faces.context.FacesContext;

import com.crystaldecisions.reports.sdk.ParameterFieldController;

import com.crystaldecisions.reports.sdk.ReportClientDocument;

import com.crystaldecisions.sdk.occa.report.lib.ReportSDKException;

public class LIC3360{

private String licenseNum="0009/K/2005";

private String signIn="nonvice";

final String USER = "USER";

final String PASSWORD = "PASSWORD";

public String getLicenseNum() {

return licenseNum;

}

public void setLicenseNum(String licenseNum) {

this.licenseNum = licenseNum;

}

public String getSignIn() {

return signIn;

}

public void setSignIn(String signIn) {

this.signIn = signIn;

}

public String postMe(){

String reportType ="LIC3360";

String postLicenseNum = this.licenseNum;

String postSingIn = this.signIn;

FacesContext context = FacesContext.getCurrentInstance();

ExternalContext app = context.getExternalContext();

Map<Object, Object> sessionMap = app.getSessionMap();

ReportClientDocument reportClientDoc = new ReportClientDocument();

try{

reportClientDoc.open(reportType + ".rpt", 0);

ParameterFieldController paramFieldController = reportClientDoc.getDataDefController().getParameterFieldController();

paramFieldController.setCurrentValue("", "@lic_num", postLicenseNum);

paramFieldController.setCurrentValue("", "@person", postSingIn);

//set final

reportClientDoc.getDatabaseController().logon(USER, PASSWORD);

sessionMap.put("reportType", reportType);

sessionMap.put(reportType, reportClientDoc.getReportSource());

return "post";

}

catch(ReportSDKException e){

System.out.println("ReportSDKException!!!!!!!");

}

catch(Exception e){

System.out.println("Other Exception!!!!!!!");

}

return "post";
