Thank you it helped.

I am using ActiveXObject for some print jobs what I doing is placing java class file on Desktop and doing stuff as follows:
var shell = new ActiveXObject("WScript.Shell"); shell.run("cmd /c java HelloWorldPrinter1 \""+output+"\"");

It works fine.

I have moved my class file into C:\printjob

So I tried as follows:
var shell = new ActiveXObject("WScript.Shell"); shell.run("cmd /c C:/printjobjava/HelloWorldPrinter1 \""+output+"\"");

It is not working.

How can put path of a file correctly in ActiveXObject?

I am having a program to send mail as follows:

I am giving user name and password correctly. I checked it with sending mail from browser and it is working

import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class sendMail { String toMail = ""; String frmMail = ""; String frmPass = ""; String subj = ""; String body = ""; public sendMail(String toMail, String frmMail, String frmPass, String subj, String body) { this.toMail = toMail; this.frmMail = frmMail; this.frmPass = frmPass; this.subj = subj; this.body = body; } public String mailProcess() { String mailProcessed = ""; Properties props = new Properties(); props.put("mail.smtp.host", "smtp.bizmail.yahoo.com"); props.put("mail.smtp.socketFactory.port", "465"); props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "465"); Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(frmMail, frmPass); } }); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress(frmMail)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toMail)); message.setSubject(subj); message.setText(body); Transport.send(message); //System.out.println("Done"); mailProcessed = "true"; } catch (MessagingException e) { mailProcessed = e.toString(); //throw new RuntimeException(e); } return mailProcessed; } }

But I am getting the following error:
javax.mail.AuthenticationFailedException: 535 5.7.8 Error: authentication failed: authentication failure

Please help guys!!

I want to implement Real time notification in my page. Suppose I have page1 and page2. An action of page1, I need to implement the notification on page2. I have noted a tutorial in JSF which is called Primefaces. http://www.primefaces.org/showcase/push/notify.xhtml. Can you guys suggest anything similar in jsp/servlets?

I am getting the following error, while accessing the site hosted in Microsoft Azure Virtual Server after waiting for few minutes.



502 Bad Gateway The proxy server received an invalid response from an upstream server.



**The most confusing part is that, if we refresh the page, it works perfectly fine and loads very fast**



The following is the configuration:



OS: Windows Server 2012, VC 14 Webserver: Apache: 2.4.12 Tomcat: 8.0.23 Connector: Mod_JK 1.2.40

Apache workers conf:

worker.list=worker1 worker.worker1.type=ajp13 worker.worker1.host=localhost worker.worker1.port=8009



The following is the lines from the log file



[Mon Jul 20 08:21:05 2015][2640:996] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1291): (w_tc) can't receive the response header message from tomcat, network problems or tomcat (xxx.xxx.xxx.xxx:8009) is down (errno=60) [Mon Jul 20 08:21:05 2015][2640:996] [error] ajp_get_reply::jk_ajp_common.c (2176): (w_tc) Tomcat is down or refused connection.

So you mean I need to create GUID(Which will be universally unique id) on each login and save in session? Sounds like a good idea. Can you elaborate buddy?

It is a good idea. By the way it will not work in IE. Because window.name method won't work in IE!!

I am using jsp for view pages and servlet for setting resetting sessions

I am developing an application that needs to logged out when using different tabs just like Gmail

The Scenario is like this

let us assume we have user1 and user2

step1: I have logged in as user1 in a browser

step2: I take new tab in the same browser and log in as user2. At this moment I want user1 to be logged off automatically from tab1.

In current scenario the first tab automatically replaces user1 with user2.

I need it like Gmail when I login as different user from new tab then the first tab automatically get logged out with a message.

Please advice me how to do this?

I have the following program to read and list the serial port,

import gnu.io.*; import java.util.Enumeration; import java.io.InputStream; public class Connectnow implements Runnable, SerialPortEventListener { static CommPortIdentifier portId; static Enumeration portList; InputStream inputStream; SerialPort serialPort; Thread readThread; byte[] readBuffer; public static void main(String[] args) { portList = CommPortIdentifier.getPortIdentifiers(); System.out.println("portList=" + portList); System.out.println(portList.hasMoreElements()); while (portList.hasMoreElements()) { System.out.println("yes"); CommPortIdentifier portId = (CommPortIdentifier)portList.nextElement(); System.out.println("portId=" + portId); } } public void run() { } public void serialEvent(SerialPortEvent ev) { } }
I am using RXTX library for it.

I have compiled and run the java program as follows:

C:\SMS\work>javac Connectnow.java

C:\SMS\work>java Connectnow
portList=gnu.io.CommPortEnumerator@5e481248
false
I am getting the value of portList.hasMoreElements() as false. What to do? I have set all the things in the RXTX library correctly. I am using Windows 8.1 64bit system. Please help me. Why it is coming as false?
