Why does a variable set in java class appear null in message body

Hello,
I set my variable in the java class like this:
DocumentProcessor dp = new DocumentProcessor(
                                                  control_file, path, working_dir );
               Properties prop = new Properties();
               prop.put( "user-variable:XMLPUB_BODY_VAR", "from_email" );
               dp.setConfig(prop);
               dp.process();
and in the control file like this:
<xapi:message id="123" to="${C_EMAIL_ADDR}" attachment="true" content_type="html/text" subject="Remittance Advice for check#${C_CHECK_NUM} ">Hello,
Attached is the remittance advice: #${C_CHECK_NUM}
If you have any queries, please send an email to: ${XMLPUB_BODY_VAR}
The problem is that he XMLPUB_BODY_VAR appears null. Is this a know problem? Any solutions?

does anyone know of this bug? I've heard similar problems before where some of the variables in the email content don't mysteriously get replaced.
Is this a known bug?

Binding a JavaFX variable to a Java class instance variable

Hi,
I am pretty new to JavaFX but have been developing in Java for many years. I am trying to develop a JavaFX webservice client. What I am doing is creating a basic scene that displays the data values that I am polling with a Java class that extends Thread. The Java class is reading temperature and voltage from a remote server and storing the response in an instance variable. I would like to bind a JavaFx variable to the Java class instance variable so that I can display the values whenever they change.
var conn: WebserviceConnection; // Java class that extends Thread
var response: WebserviceResponse;
try {
conn = new WebserviceConnection("some_url");
conn.start();
Thread.sleep(10000);
} catch (e:Exception) {
e.printStackTrace();
def bindTemp = bind conn.getResponse().getTemperature();
def bindVolt = bind conn.getResponse().getVoltage();
The WebserviceConnection class is opening a socket connection and reading some data in a separate thread. A regular socket connection is used because the server is not using HTTP.
When I run the application, the bindTemp and bindVolt are not updated whenever new data values are received.
Am I missing something with how bind works? Can I do what I want to do with 'bind'. I basically want to run a separate thread to retrieve data and want my UI to be updated when the data changes.
Is there a better way to do this than the way I am trying to do it?
Thanks for any help in advance.

Hi,
If you don't want to constantly poll for value change, you can use the observer design pattern, but you need to modify the classes that serve the values to javafx.
Heres a simple example:
The Thread which updates a value in every second:
// TimeServer.java
public class TimeServer extends Thread {
    private boolean interrupted = false;
    public ValueObject valueObject = new ValueObject();
    @Override
    public void run() {
        while (!interrupted) {
            try {
                valueObject.setValue(Long.toString(System.currentTimeMillis()));
                sleep(1000);
            } catch (InterruptedException ex) {
                interrupted = true;
}The ValueObject class which contains the values we want to bind in javafx:
// ValueObject.java
import java.util.Observable;
public class ValueObject extends Observable {
    private String value;
    public String getValue() {
        return this.value;
    public void setValue(String value) {
        this.value = value;
        fireNotify();
    private void fireNotify() {
        setChanged();
        notifyObservers();
}We also need an adapter class in JFX so we can use bind:
// ValueObjectAdapter.fx
import java.util.Observer;
import java.util.Observable;
public class ValueObjectAdapter extends Observer {
    public-read var value : String;
    public var valueObject : ValueObject
        on replace { valueObject.addObserver(this)}
    override function update(observable: Observable, arg: Object) {
         // We need to run every code in the JFX EDT
         // do not change if the update method can be called outside the Event Dispatch Thread!
         FX.deferAction(
             function(): Void {
                value = valueObject.getValue();
}And finally the main JFX code which displays the canging value:
// Main.fx
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import threadbindfx.TimeServer;
var timeServer : TimeServer;
var valueObjectAdapter : ValueObjectAdapter = new ValueObjectAdapter();
timeServer = new TimeServer();
valueObjectAdapter.valueObject = timeServer.valueObject;
timeServer.start();
Stage {
    title: "Time Application"
    width: 250
    height: 80
    scene: Scene {
        content: Text {
            font : Font {
                size : 24
            x : 10, y : 30
            content: bind valueObjectAdapter.value;
}This approach uses less cpu time than constant polling, and changes aren't dependent on the polling interval.
However this cannot be applied to code which you cannot change obviously.
I hope this helps.

Why does illustartor CC open then crashes and i get a message saying windows don't know the prob?

why does illustartor CC open then crashes and i get a message saying windows does not know what the problem is. everytime i open it, Now i know it works on my computer becuase i've used illustartor plenty of times on my current desktop but ever since today its been acting wierd and work so i've unistalling and reinstalling but still nothing works then i tried installing on another hardrive still did not work and i cleaned out my registryies, optimized my disk, and cleaned temp files tooo so i just do not know what went wrong and i really need help i have class assignments that i have to get done in illustartor so if anyone can help me and let me know what the problem is and what i have to do i would really apreciate it.

Hi J,
- Do you see an AICC splash screen? If yes then could you please let us know where exactly it crashes i.e. while loading which plugin or font?
- Do you have any 3rd party plugins installed? Can you please remove those (do take a backup of them) and see if AI launches fine? This way you would be able to find the plugin creating the problem.
- Did you install any OS or Ai update after which it started showing the problem?
- Please check if you have all the Verdana family fonts installed.
Let me know if any of these work.
Thanks,
Dhirendra

To obtain the value of a session variable in a JAVA class

Hello again.
I have a JSP page, in witch I kept a session variable with a value, and later (in the same JSP page) I use a JAVA class to obtain the value stored in this session variable (I make this to verify that this works well and that this is possible)
When I run the file, I obtain the following error:

Why JMS if we can use JAVA classes for the same

if we can communicate using the java classes which are protable and platform independent why do we have to use JMS for that. what is so specific about it and what is the benefit that makes it outstanding

James/Steve,
I feel that some of your points are misleading. The original authors point was a comparison against JMS and other means of achieving similar functionality with Java. Regarding your combined points:
2) Scalability is something that can be achieved regardless of whether JMS is used. Clustering has nothing to do with JMS, each vendors clustering implementation is entirely proprietary.
4) Aside from the inclusion of JNDI the JMS specification offers nothing for management. You only need to look through this forum at the amount of times a question like �how do I make a topic programmatically?� has been asked. All good JMS vendors offer management API�s and tools but all are vendor specific implementations.
10) There is no JMS standard for load balancing. The generic round robin features of a JMS queue falls a long way short of true �load balancing�. Any vendor (ourselves included) that offers load balancing does so in an entirely proprietary manner.
11) Again�JMS provides no standards for clustering of running one or more server. This is entirely down to implementation and functionality is vendor specific.
12) Dead Message/Letter Queues are not defined in JMS
14) What does serialization have to do with the original point? How one chooses to serialize their content ( XML, Object Serialization, Externalizable etc..) is equally applicable to both bespoke Java coding and JMS implementations.
To birs1982:
JMS is merely a collection of interfaces that define how one might read and write to a topic or queue. Vendors (both open source and commercial) recognize that these interfaces alone are not enough to offer an entire middleware messaging solution and complete the offering with sophisticated management, resilience, clustering, security and other value added features. These value added features require considerable effort to get right as do things like scalability and performance.
Given JMS like messaging is almost commodity now (just look at the amount of JMS vendors that have leaped into the ESB space) and a common (perhaps essential) infrastructure component why produce it yourself? Surely your time is better spent serving your clients and business lines rather that writing what amounts to plumbing. All the hard work has been done and the price for this hard work (depending on your requirements) is anything from free to many thousands of pounds.

How to access variables declared in java class file from jsp

i have a java package which reads values from property file. i have imported the package.classname in jsp file and also i have created an object for the class file like
classname object=new classname();
now iam able to access only the methods defined in the class but not the variables. i have defined connection properties in class file.
in jsp i need to use
statement=con.createstatement(); but it shows variable not declared.
con is declared in java class file.
how to access the variables?
thanks

here is the code

is this the right procedure to access bean variables

Accessing String variables from several JAVA classes

Hi.
I have several java classes that accesses the same String variables. Instead of putting the String declarations in every java files, how can I put these declarations in a single file source, and get each java class to get the variables data from this file ?
Please advice.
Thanks.

hi, of course you can solve it by the following methods:
Method 1. define a superclass including the common string variable, and extend other classes from the superclass.
Method 2. define a class , and define your common string variable as a static variable in it. In your other classes, you can call the string variable.
Method 3. define it at your each classes.

Why does the Time Capsule of my neighbour appears and not mine?

Why does the The Time Capsule of my neighbour appears and not mine? I tried everything.
What generation is your neighbour's and what generation is yours??
Sometimes the changes in the TC and firmware can make wireless fail.. also location is important.. the location of your neighbours might be better than yours.. his also might interfere with yours.. set a fixed channel and try the various channels.
Can I use the Capsule as merely a back up without making use of Wifi? By connecting by cable to the computer?
Sure, but you need to work out how the network is going to work.. if you are still picking up network from wireless.. then set static ip for the TC in a different IP range.. set no gateway (router ip) or dns and it will work just fine.

How to log the error/variables info in java classes

We are using the third party jar and the jar is independent to the application. So this is why I am not able to see any errors in the web server log. In that file using the below sample code is using. And my problem is I am not able to print the variables info either in web page or in the terminal. Please can any one suggest how to make it possible(to print the variables info).Just fyi, the methods in this class are calling by Java bean and the java bean in turn calling by servlet.

JSP does not have visibility of java classes in simple Web Module Project

Dear Experts
I am developing what I thought would be a very simple Web Module Project for a simple webservice
to allow a user to logon to Netweaver Portal with a simple logon and password.
I have not done this in over 8 years, and am somewhat rusty.
The webservice is package in a .war and is deployed via an Enterprise Application project as a .ear.
The issue I am having is that I want to enhance the presentation of the webservice through the
provision of css and adding a couple of images. The "libraries" are visibile in the build path of web
module project.
At the top of my .jsp for logon form I want to import some java libraries in order
to get String webpath = componentRequest.getWebResourcePath()"/":
<%@ page session = "true"%>
<%@ page import = "com.sapportals.portal.prt.resource.IResource" %>
<%@ page import="com.sap.security.core.sapmimp.logon.SAPMLogonLogic" %>
<%@ page import="com.sap.security.core.sapmimp.logon.SAPMLogonCertLogic" %>
<%@ page import="com.sap.security.core.logonadmin.IAccessToLogic" %>
<%@ page import="com.sap.security.core.logonadmin.ComponentAccessToLogic" %>
<% IAccessToLogic proxy = new ComponentAccessToLogic (componentRequest, aResponse, IAccessToLogic.ENV_LOGONCOMPONENT);
final boolean inPortal = true;
String webpath = componentRequest.getWebResourcePath()"/";
// todo: find layout schema...
aResponse.addResource(componentRequest.getResource(IResource.CSS, "css/main2.css"));
%>
However, during runtime the libraries are unknown and I get the following SAPJ2 EE errors
indicating the methods etc are not known to the jsp:
