Problem with a simple GRE tunnel

Hello everyone:
I have a problem with a simple GRE tunnel, and can not make it work, the problem lies in the instruction "tunnel source loopback-0" if I use this command does not work, now if I use "tunnel source <ip wan >" if it works, someone can tell me why?
Thanks for your help

Hello, thank you for the answer, as to your question, I have no connectivity within the tunnel, whether from Router 1, I ping 10.10.1.2 not get response ...
Now both routers remove the loopback, and the interface tunnel 0 change the tunnel source to "tunnel source " tunnel works perfectly, the problem is when I have to use the loopback. Unfortunately achieved when the tunnel work, this will have to endure multicast, and all the examples found carrying a loopback as' source '... but this is a step back ..

Problems with a simple stop watch program

I would appreciate help sorting out a problem with a simple stop watch program. The problem is that it throws up inappropriate values. For example, the first time I ran it today it showed the best time at 19 seconds before the actual time had reached 2 seconds. I restarted the program and it ran correctly until about the thirtieth time I started it again when it was going okay until the display suddenly changed to something like '-50:31:30:50-'. I don't have screenshot because I had twenty thirteen year olds suddenly yelling at me that it was wrong. I clicked 'Stop' and then 'Start' again and it ran correctly.
I have posted the whole code (minus the GUI section) because I want you to see that the program is very, very simple. I can't see where it could go wrong. I would appreciate any hints.
public class StopWatch extends javax.swing.JFrame implements Runnable {
    int startTime, stopTime, totalTime, bestTime;
    private volatile Thread myThread = null;
    /** Creates new form StopWatch */
    public StopWatch() {
     startTime = 0;
     stopTime = 0;
     totalTime = 0;
     bestTime = 0;
     initComponents();
    public void run() {
     Thread thisThread = Thread.currentThread();
     while(myThread == thisThread) {
         try {
          Thread.sleep(100);
          getEnd();
         } catch (InterruptedException e) {}
    public void start() {
     if(myThread == null) {
         myThread = new Thread(this);
         myThread.start();
    public void getStart() {
     Calendar now = Calendar.getInstance();
     startTime = (now.get(Calendar.MINUTE) * 60) + now.get(Calendar.SECOND);
    public void getEnd() {
     Calendar now1 = Calendar.getInstance();
     stopTime = (now1.get(Calendar.MINUTE) * 60) + now1.get(Calendar.SECOND);
     totalTime = stopTime - startTime;
     setLabel();
     if(bestTime < totalTime) bestTime = totalTime;
    public void setLabel() {
     if((totalTime % 60) < 10) {
         jLabel1.setText(""+totalTime/60+ ":0"+(totalTime % 60));
     } else {
         jLabel1.setText(""+totalTime/60 + ":"+(totalTime % 60));
     if((bestTime % 60) < 10) {
         jLabel3.setText(""+bestTime/60+ ":0"+(bestTime % 60));
     } else {
         jLabel3.setText(""+bestTime/60 + ":"+(bestTime % 60));
    private void ButtonClicked(java.awt.event.ActionEvent evt) {
     JButton temp = (JButton) evt.getSource();
     if(temp.equals(jButton1)) {
         start();
         getStart();
     if(temp.equals(jButton2)) {
         getEnd();
         myThread = null;
     * @param args the command line arguments
    public static void main(String args[]) {
     java.awt.EventQueue.invokeLater(new Runnable() {
         public void run() {
          new StopWatch().setVisible(true);
    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JButton jButton2;
    private javax.swing.JLabel jLabel1;
    private javax.swing.JLabel jLabel2;
    private javax.swing.JLabel jLabel3;
    private javax.swing.JPanel jPanel1;
    // End of variables declaration
}

Although I appreciate this information, it still doesn't actually solve the problem. I can't see an error in the logic (or the code). The fact that the formatting works most of the time suggests that the problem does not lie there. As well, I use the same basic code for other time related displays e.g. countdown timers where the user sets a maximum time and the computer stops when zero is reached. I haven't had an error is these programs.
For me, it is such a simple program and the room for errors seem small. I am guessing that I have misunderstood something about dates, but I obviously don't know.
Again, thank you for taking the time to look at the problem and post a reply.

Problem with XI simple scinario

Hi Friends,
I am new in XI, I am working on simple xi scenario. whn i create sales order i wan to send order confirmation . for that i am using ORDRSP. I had done all the ale settings and able to generaet idoc and send it to XI . Now the problem is that,once the idoc is sent from R/3 system, on the XI system I am not able to see it in transaction SXMB_MONI. I am able to c that idoc in transaction WE02,with error in XI system.
So please let me knw,how to solve this.
Regards,
Brij.....

hi,
plz once check in idx5 in xi server..
if u r able to see u r idoc in that then u can confirm u er IDOC reached to XI server..
if IDOC is not there in IDX5, plz do check in RFC destination remote connection, if u get the EASY ACCESS MENU of the XI system, then RFC destination is fine.
and once check port and partner profile also....
if u check all these things.. hope u r problem will be solved.
Thanks,
Madhav

Problem with a simple Crystal 10 report

Help please!!
I am writing what should be a simple report in Crystal 10 which is acting oddly.
The report is built on 3 tables which sit on a SQL database and are linked through ODBC views. The tables are property, referral and incident and the property table is the one that exists in all cases. All three have a Property ID and the other two tables are linked to the property table through two full outer join connections. A property can have a referral or an incident or both.
I just want to create a report which lists all the unique properties which have a referral or an incident which has been created within a particular timescale.
The filter I am using is:
{est_property.est_address_postalcode} = "AB12 5NX" and
(({est_referral.CreatedOn}>={?Start date}) and ({est_referral.CreatedOn}<={?End date}))
or
(({Incident.CreatedOn}>={?Start date})and ( {Incident.CreatedOn}<={?End date} ))
Note the 'AB12 5NX' bit is just to speed the testing process up as the databases that I am querying are large.
The version I am running is 10.0.0.533 although I am currently (very slowly) downloading SP6.
Thanks,
John

I have made some progress on this. I think the problem is because the filter fails when the tables it is querying have Nulls in them.
I have just tried building the filter again with an "if the 'created on' field in the referral table is NULL then just query on the incident table" type of query:
if isnull({est_referral.CreatedOn})=FALSE then
    {est_property.est_address_postalcode} = "AB12 5NX" and
    ({?Start date}<={est_referral.CreatedOn} and {est_referral.CreatedOn}<={?End date})
    or
    {est_property.est_address_postalcode} = "AB12 5NX" and
    ({?Start date}<={Incident.CreatedOn}and {Incident.CreatedOn}<={?End date} )
else
    {est_property.est_address_postalcode} = "AB12 5NX" and
    ({?Start date}<={Incident.CreatedOn}and {Incident.CreatedOn}<={?End date} )
This seems to work but seems to be very heavy on the processing. It would also require a very complex bit of coding when I start building the proper query which actually requires four sub-tables to be queried rather than ust two!
So still help required!
Thanks.

WAAS with IPSEC or GRE tunnels

Hello,
I have a client with HQ and remote site, I need to implement WAAS between them.
issue is they are connected GRE over IPsec over MPLS WAAN, is there anything to take care about when implementing WAAS in GRE/IPSEC deployment.
Thanks & BR
Moamen

I would keep in mind the following things...
1. Interception - You have to ensure you intercept the traffic outside the tunnels, otherwise you won't get any compression. Hardware based switches like the Cat6K cannot use WCCP on tunnel interfaces. Software based routers can do interception on tunnel interfaces, but don't scale as much as the hardware assisted platforms.
2. Packet size - if you are getting excessive fragmentation, try lowering the Optimized MSS value on the WAEs to under what you need for headers. WAAS default is 1432.
Other then that, what you have is a pretty normal installation situation.
Thanks,
Dan

A few notes:
1. You seem to have either a VPD policy active or you're using views that add some more predicates to the query, according to the plan posted (the access on the PK_OPERATOR_GROUP index). Could this make any difference?
2. The estimates of the optimizer are really very accurate - actually astonishing - compared to the tkprof output, so the optimizer seems to have a very good picture of the cardinalities and therefore the plan should be reasonable.
3. Did you gather index statistics as well (using COMPUTE STATISTICS when creating the index or "cascade=>true" option) when gathering the statistics? I assume you're on 9i, not 10g according to the plan and tkprof output.
4. Looking at the amount of data that needs to be processed it is unlikely that this query takes only 3 seconds, the 20 seconds seems to be OK.
If you are sure that for a similar amount of underlying data the query took only 3 seconds in the past it would be very useful if you - by any chance - have an execution plan at hand of that "3 seconds" execution.
One thing that I could imagine is that due to the monthly data growth that you've mentioned one or more of the tables have exceeded the "2% of the buffer cache" threshold and therefore are no longer treated as "small tables" in the buffer cache. This could explain that you now have more physical reads than in the past and therefore the query takes longer to execute than before.
I think that this query could only be executed in 3 seconds if it is somewhere using a predicate that is more selective and could benefit from an indexed access path.

Basic (and I mean basic) java problem with a simple hello world script

I have a simple cut-and-paste html page and java class in my /home/jc158027/java directory.
jc158027> cat HelloWorld.java
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet{
Label helloLabel = new Label ("Hello World");
public void init () {
setBackground (Color.yellow);
add (helloLabel);
}Ok, so I javac HelloWorld.java and get HelloWorld.class, so far so good.
Next I create my html page:
jc158027> cat hw.html
<HTML>
<HEAD>
<TITLE>Jay's Java Test Page</TITLE>
<BODY>
<HR>
This line of text comes before the applet.<P>
<APPLET CODE = 'HelloWorld.class" WIDTH=500 Height=90>
</APPLET>
<P>
This line of text comes after the applet.
</BODY>
</HTML>The result is that the text lines work, I get a nice grey box with no applet running. Looking at my console I get the following error:
Caused by: java.io.FileNotFoundException: /home/jc158027/java/HelloWorld/class".class (No such file or directory)
What I don't understand is the HelloWorld/class".class portion, shouldn't it be just either HelloWorld".class or HelloWorld/class, it is as though it is trying to look in a directory (class) that does not exist.
What am I missing here?

And if you put dots in where it expects a class name, it assumes those dots are to separate levels in a package name.
So it was looking for a class named "class", which would be in a file called class.class, in a package named "HelloWorld". Packages correspond to directories relative to some classpath root, so it looked for the directory HelloWorld to be the parent of the classes in the HelloWorld package.

Problem with very simple 2 threads java application

Hi,
As fa as i'm concerned this is a thread licecycle:
1. thread created: it is dead.
2. thread started: it is now alive.
3. thread executes its run method: it is alive during this method.
4. after thread finishes its run method: it is dead.
No I have simple JUnit code:
public void testThreads() throws Exception {
WorkTest work = new WorkTest() {
public void release() {
// TODO Auto-generated method stub
public void run() {
for (int i=0;i<1000;i++){
log.debug(i+":11111111111");
//System.out.println(i+":11111111111");
WorkTest work2 = new WorkTest() {
public void release() {
// TODO Auto-generated method stub
public void run() {
for (int i=0;i<1000;i++){
log.debug(i+":22222222222");
Thread workerThread = new Thread(work);
Thread workerThread2 = new Thread(work2);
workerThread.start();
//workerThread.join();
workerThread2.start();
//workerThread2.join();
And
public interface WorkTest extends Runnable {
public abstract void release();
And that's it..
On the console I see 999 iterations of both threads only if i uncomment
//workerThread.join();
//workerThread2.join();
In other case I see random number of iterations - JUNIT finishes and Thread1 made 54 and Thread2 233 iterations - the numbers are different every time i start the JUnit..
What I want? Not to wait until the first one finishes - I want them to start at the same time and they must FINISH their tasks...
Please help me asap :(

This is very simple... Look at your code:
workerThread.start();
workerThread.join();
workerThread2.start();
workerThread2.join();What are you doing here? You start the first thread, then you call join(), which waits until it finishes. Then after it's finished, you start the second thread and wait until it finishes. You should simply do this:
workerThread.start();
workerThread2.start();
workerThread.join();
workerThread2.join();I.e., you start the 2 threads and then you wait (first for the first one, then for the second one).

Problem with getNodeValue() - simple Java XPath question

I am trying to extract the node values from a XML file:
<root>
<frame>
     <boxes>
       <box>
          <spec>22</spec>
          <spec>2222</spec>
       </box>
       <box>
          <spec id="BA" value="short"/>
          <spec id="BB" value="thin"/>
          <spec id="BC" value="black"/>
          <spec id="BD" value="full"/>
          <spec id="BE" value="7"/>
          <spec id="BF" value="deactive"/>
       </box>
     </boxes>
     <circles>
       <circle id="CA" value="blue"/>
       <circle id="CB" value="green"/>
     </circles>
</frame>
</root>I use this code:
         XPathFactory factory = XPathFactory.newInstance();
         XPath xpath = factory.newXPath();
         XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");
         Object result = xPathExpression.evaluate(doc, XPathConstants.NODESET);
         NodeList nodes = (NodeList) result;
         for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
         }But only:
null
null
null
null
null
null
null
null
get printed. I would have assumed:
22
2222
null
null
null
null
null
null
since the two first spec nodes contains the above numbers. Any ideas?

change this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");to this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec/text()");Need to xpath all the way down to the text of the node.
You could use
System.out.println(nodes.item(i).getTextContent());with your current xpath but if the spec node has children, these will also be included in the output.

Problem with a simple query

Hey. I've got a table which contains only one entry:
Table "users":
id | date | user | pass | profile | last_logged
1 | ... | evo | ... | ... | ...
My query is: "SELECT * FROM users WHERE user=evo". The problem is that im always gettings a null pointer exception, but if I get the data by refering to the id (WHERE id=1) then it works! Why is this?
I've got a login system which takes the username from the form and attempts to get the id corresponding to the user value. But it just won't work. help appreciated. Thanks.

Is the user column of type string and evo a string value?
Which database are you using?
Don't you have to put single quotes around that?
String query = "SELECT * FROM users WHERE user = 'evo'"MOD

Having Problems With a Simple Thing: ImageIcons

this is part of my code:
public void buildToolBar(){
saveIcon = new ImageIcon("images/save.jpg");
searchIcon = new ImageIcon("images/search.jpg");
saveButton = new JButton(saveIcon);
searchButton = new JButton(searchIcon);
toolBar = new JToolBar();
toolBar.setFloatable(false);
toolBar.add(saveButton);
toolBar.add(searchButton);
i'm using NetBeans 5.5, and for some reason this doesn't work. the buttons show up in the toolbar but they do not have the images that i want in them. maybe i'm putting the images in the wrong directory?

No size has got nothing to do with it. Troubleshooting, I would ask these questions:
1. What image format are you using? Can Java read it?
2. Double-check the file name and be careful with upper/lower case.
3. Make sure it is in the directory you think it should ne in.
Here's a quick app to see if Java can read and display the file:
import java.io.*;
import java.awt.event.*;
import javax.swing.*;
public class ImageView {
    public static void main(String[] args) {
        final JLabel label = new JLabel("", SwingConstants.CENTER);
        Action open = new AbstractAction("Open"){
            JFileChooser chooser = new JFileChooser();
            public void actionPerformed(ActionEvent evt) {
                if (chooser.showOpenDialog(label) == JFileChooser.APPROVE_OPTION) {
                    label.setIcon(new ImageIcon(chooser.getSelectedFile().getPath()));
        JMenu menu = new JMenu("File");
        menu.add(open);
        JMenuBar bar = new JMenuBar();
        bar.add(menu);
        JFrame f = new JFrame("ImageView");
        f.setJMenuBar(bar);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(label));
        f.setSize(600,400);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
}

I´m having problems with a simple synchronized move

When using the "flex_start" function with the parameter AxisOrVectorSpace
set as 0X00 (MULTIPLE_AXES), is it possible that some axes move ahead of the others or does the Flex Software secure the synchronization?
I use motion controler 7344.

Please allow me to clarify my previous statement. Vector spaces greatly simplify synchronized movement across multiple axes because the generated trajectory is done on the vector. It is possible to start and end the moves of multiple axes without using a vector space; however, you will have to use a multi-start and then calculate the appropriate move constraints for each axis that brings it to the end of travel with the other axes.
The FlexMotion software will attempt to adhere to the calculated trajectory for each axis, and assuming these parameters are properly set such that all axes arrive at their end of travel at the same time, the axes should maintain synchronization. Factors such as one axis facing a significantly greater load than the others m
ay cause that axis to temporarily get out of sync, but this should only be for one PID loop update period. If you are using a closed-loop stepper system and your motor is missing steps that axis may deviate from its calculated trajectory, and the FlexMotion software will try to compensate for this at the end of the movement by doing up to three pull-in moves.
I hope this better answers your question. Best wishes!

Little problem with a simple schematic

I was trying the new Multisim 11 and so I decided to reproduce the schematic below, which I took from a book. It should be led flashing at intervals, but I can't get it to work. Can someone kindly tell me why it isn't working(flashing)?

Hello Poldoj and Andrew. I agree with Andrew. It didn't work with 470 kOhm (the time is long, but nothing at all happens - even if you wait a long time). It seems that the simulation never reaches the flash-point. I lowered 470 kOhm to 220 kOhm and then it works. In the simulation, the LED will flash (briefly), but it will not discharge the 2.2 uF entirely. I added a 100 Ohm resistor in across the LED to discharge the capacitor more. It is easier to see what happens in the graph then, but is probably not needed in the real circuit. See the two graphs with and without the 100 Ohm.

Little problem with a simple function

class function{
     public static int adjust (int m, int[] n){
          m++;
          n[0]++;
          return 1;
     public static void main(String [] args){
          int m = 4;
          int[] n = {4};
          adjust(m,n);
          System.out.println(m);
          System.out.print(n[0]);
Why does it print:
4
5
and not:
5
5
Why does n[0] increase by one and not m?
Is there a simple way to fix this, so that both gets the value 5?

Because Java is always pass-by-value.
A copy of m is passed, 1 is added to that copy, the original m is never touched.
A copy of the reference to the array is passed, 1 is added to the 0th element of the array, the original variable (reference) n is never touched but both it and the copy reference the same array.
