Question in ThreadPool

Hi All,
I am trying to create an application which runs a set of tasks(Runnable) perodically using a Thread pool.
The time period being taken from a config file(day, month,yearly).
Can anyone please tell me how to capture the change in the time period in the config file, while the application is still running. I do not want to stop the application.
Thanks in advence.

hey aconst_null,
apart from quartz what can we use???

ThreadPool Related-few question

Hi,
I am using Thread pool in my application . where i am creating
threads (and assigning name ChildThread1,ChildThread2 ..) and put them in the
Thread pool using the execute() method.
In my application i try to get the name of the current active threads.
So i use
<code>
Thread[] threadArray = new Thread[Thread.activeCount()];
int numThreads = Thread.enumerate(threadArray);
for (int i = 0; i < numThreads; i++) {
System.out.println(threadArray.getName());
</code>
to get the active threads.
But i found that it did not print the ChildThread name(as i defining at the time of
creation of childthread).Instead of that it prints
pool-1-thread-1
pool-1-thread-2
pool-1-thread-3
My question is that
1.whether this two threads(ChildThread1,pool-1-thread-1) denote the same one with different name.
2.ithey are different then how can i get the name of childThread ?
Thanks & Regards

Hello,
I understand that you are using the concurrent api, some code like this
ExecutorService executor = Executors.newFixedThreadPool(pool_size);The pool creates a number of threads, say 3, and then run the runnable tasks you load in the pool in this threads executing the runnable method of the task.
Your runnable task never become a thread runs inside a thread of the pool.
When you list your application threads you see the names of the threads in the pool not the names of the runnable tasks.
I hope i make my self understandable.

This is on the default index.jsp page that installs with Apache Tomcat/4.1.18... at http://localhost:8080/index.jsp which maps to C:\Program Files\Apache Group\Tomcat 4.1\webapps\ROOT\index.jsp
by now I have way too many java sdks installed...
C:\Program Files\Java\j2re1.4.1_01
C:\Program Files\Java\j2re1.4.0_03
C:\j2sdk1.4.0_03
C:\j2sdkee1.4
The first one I tried got me the same error I am getting now.. and since I have tried different versions changing JAVA_HOME
Right now..
JAVA_HOME = C:\j2sdkee1.4
CATALINA_HOME = C:\Program Files\Apache Group\Tomcat 4.1
I have no idea what's going on here not having much experience in settting up web servers or java SDKs. But in order to learn the stuff I have planned to I need teh following to get up and running on Win2K.. any help is greatly appreciated.
Java JDK 1.4.
Tomcat servlet\JSP engine 4.0.1.
MySQL database 3.23.46
If I stick a standard html page in the tomcat root it will show just fine.. so I suspect the whole Java thing is buggin for some reason.
Here's the full text of the returned error followed by the text of the index.jsp file

I ended up uninstalling every java this and that.. and tomcat.
Then installing only the j2sdk1.4.0_03 SDK.
Then set up JAVA_HOME for all users and modified the path with full path to the bin (c:\j2sdk1.4.0_03\bin)
Lastly I reinstalled tomcat and, voila, everything was working.
It can be quite maddening when you THINK you did everything by the boook and something doesn't work. When you replied and confirmed that I was on the right track.. uninstalling and trying yet again became les frustrating an option.
Thanks.
BTW- I needed this env to do the projects in what sems to be a very interesting book.. "macromedia Flash MC application design and development" by Jessica Speigel .. published by New Riders.
Her flash help website is at www.were-here.com.. the projects in the book are for flash-based multiplayer games and multi-user formums and such.

Best practice question for implementing a custom component

I'm implementing a custom component which renders multiple <input type="text" .../> controls as part of it. The examples I've seen that do something similar use the ResponseWriter to generate the markup "by hand" like:
 writer.startElement("input", component);
 writer.writeAttribute("type", "text", null);
 writer.writeAttribute("id", "foo", null);
 writer.writeAttribute("name", "foo", null);
 writer.writeAttribute("value", "hello", null);
 writer.writeAttribute("size", "20", null);
 writer.endElement("input");
I don't know about anyone else, but I HATE having to write code that manufactures this stuff - seems to me that there are already classes that do this, so why not just use those? For example, the above could be replaced with:
 HtmlInputText textField = new HtmlInputText();
 textField.setId("foo");
 textField.setValue("hello");
 textField.setSize(20);
 // just to be safe, invoke both encodeBegin() and encodeEnd(),
 // though it seems like encodeEnd() actually does the work in this case,
 // but who knows if they might change it at some point
 textField.encodeBegin(context);
 textField.encodeEnd(context);
So my question is, why does everyone seem to favor the former over the latter? Why not leverage objects that already do the (encoding) work for you?

Got it!
You JSP should have this:
<h:panelGroup styleClass="jspPanel" id="jspPanel1"></h:panelGroup>
And your code page ValueChangeListener/ActionListner should have this:
 if (findComponent(getForm1(),"myOutputText") == null)
 FacesContext facesCtx = FacesContext.getCurrentInstance();
 System.out.println("Adding component");
 HtmlOutputText output =
 (HtmlOutputText) facesCtx.getApplication().createComponent(
 HtmlOutputText.COMPONENT_TYPE);
 output.setId("myOutputText");
 output.setValue("It works");
 getJspPanel1().getChildren().add(output);
 System.out.println("Done");
 DebugUtil.printTree(FacesContext.getCurrentInstance().getViewRoot(),System.out);
 else
 System.out.println("component already added");
I just have to figure out this IOException on the closed stream - probably has to do with [immidiate="true"].
Thanks.

How to get each thread in the threadpool

Hi,everyone.I'm now learning java.util.concurrent package and I have two questions about the threadpool.
1) How to get each thread in the threadpool;
2) How to get each thread's data in the threadpool and dispaly them onto GUI;
e.g :
There are 5 threads in the threadpool(ThreadPoolExecutor) and I have 100 tasks(Runnable or Callable),every task scans a directory(every task scans a different directory),how can I display the "real-time" count of the files in the directory which the current 5 threads in the threadpool scan onto the ListView Items in the GUI?

Finally you notify the monitor when the execution has completed.

Questions on AS2 setup for eXchange 5.1.3U2

All,
I am having some difficulty setting up the AS2 sample project. We got the X12 sample up and running with not too much trouble. The question I have is regarding AS2 setup on the B2B host configuration. In the B2B repository, you have your configurations. The one I am referencing for this forum in the sample project is named envEaiupgrepoDmnA_AS2. When I look at the transport under envEaiupgrepoDmnA_AS2 which is under B2B repository, the http configuration is shown. After clicking on the http configuration, I see the various properties of the HTTP transport:
· Outbound ToPartner
· Inbound FromPartner
· ACK - Outbound ToPartner
· ACK - Inbound FromPartner
In each of those properties, I see the “End URL” configuration which seems to be a required field in the configuration. The value currently in that field is “Set value.” This would lead me to believe why our AS2 sample project isn’t working. Furthermore, when I look HTTP external system in eDesigner for that specific domain, there is no URL specified in the properties.
Please advise.
Regards,
John Ferron

Andreas,
I have actually resolved a lot of issues since the last post. The last part I have a question on is the setup of the keystore in the environment. Can you go into detail on how you set that up? A colleague initially set this up and I am going back and resolving these issues to get the sample to work. In the Sun B2B Suite AS2 Protocol Manager User's Guide on page 118, the steps they show are not exactly the same what I did in the EPM webapp. For Step 7, I did not have to add a password for the companya_cert certificate.
Could you let me know what you did to get the certificates and encryption for the AS2 sample working? Here is the exception I am currently seeing:

"there were not enough threads in the threadpool object to complete the operation" exception

Post Author: crystalmatrix
CA Forum: .NET
I have a WinForm application using a Crystal Report Viewer control that in turn connects to a CR web service to display report. The client side application runs on WinXP SP1 with .Net framework 1.1, and the server is Win2k with ASP.Net 1.1. I am using CR XI out of the box.
Users would periodically get "there were not enough threads in the threadpool object to complete the operation." exception when trying to launch the report viewer connected to the web service. The web service is a standard example implementation derived from CrystalDecisions.Web.Services.ReportServiceBase class. The problem usually happens when the user tries to open multiple report viewer forms, but once they get the error, it would continue to happen even after the user shuts down all viewer forms and then tries to launch a new one.
There are some posts on the web regarding multiple asynchronous HttpWebRequest draining threadpool when running simultaneously and each one taking a long time to complete. However, our reports all run pretty quickly and results are usually returned before the next report starts to run. So my question is: does Crystal Report Viewer control has a problem with web service in that it may hold the HttpWebRequest thread even after the report is returned, or any other problem that may prevents the asynchronous thread being released back to the Threadpool? Anyone has experienced similar problems and has a workaround?
Any advice is appreciated.

Thank you and Regards.

Hi,
Thank you for response.I have modified the program as what you told me.it can startup now,But it suspended at LoginAction,the running message is printed as following:
LoginAction.execute(ActionMapping, ActionForm, HttpServletRequest, HttpServletResponse) line: 18
RequestProcessor.processActionPerform(HttpServletRequest, HttpServletResponse, Action, ActionForm, ActionMapping) line: 419
RequestProcessor.process(HttpServletRequest, HttpServletResponse) line: 224
ActionServlet.process(HttpServletRequest, HttpServletResponse) line: 1192
ActionServlet(HttpServlet).service(HttpServletRequest, HttpServletResponse) line: 709
when I click on the information "RequestProcessor.processActionPerform",it popup a message that show "Source not found ,The jar file Struts.jar has no source attachment",Does it need to attach the source of struts.jar?
I list the LoginAction.java as following:
package classmate;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public final class LoginAction extends Action{
public ActionForward execute(
 ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response) throws Exception {
 UserForm userform = (UserForm) form;
 String name = userform.getName();
 String psw = userform.getPsw();
 if("jenny".equals(name) && "hi".equals(psw)){
 UserLoginLog ul = new UserLoginLog();
 ul.save(name,psw);
 return mapping.findForward("successed");
 }else{
 return mapping.findForward("failed");
as I debuged the program,the breakpoint line "UserForm userform = (UserForm) form; "
and the UseForm.java is listed as following:
package classmate;
import org.apache.struts.action.ActionForm;
public class UserForm extends ActionForm{
 private static final long serialVersionUID = 1L;
 private String name = null;
 private String psw = null;
 public UserForm(){}
 public void setName(String name) {
 this.name = name;
 public String getName() {
 return name;
 public void setPsw(String psw) {
 this.psw = psw;
 public String getPsw() {
 return psw;
and I have written the web.xml and struts-config.xml in above message.
how can I run through the breakpoint line so that I can access the ActionForm's Data? if anybody can tell me how to resovle it ,Please reply to help me. Thanks you.

Pros/cons of a threadpool

I've seen some example of nio servers using a threadpool and some who don't.
A little question about it:
what are the pros are of this method or why would u use a threadpool and not seperate threads.
Cons seems like its bit difficulter because of synchronisation etc.
Thanks in advance!
(idk if there is a problem that i've to unanswered questions in this forum now, tell me if so)

The purpose of a thread pool is to amortize the overhead of creating new threads over a large number of uses of the thread. You can also limit the total number of threads, which can help in low-memory situations.
See java.util.concurrent.Executor and friends.

Several CUMA questions

Hi, I'm just configuring CUMA 7.1. I have some questions about CUMA configuration. Actually, my client cannot connect to CUMA server and I coundn't find the source of this problem.
My CUMA is running, I have connection to AD and activated one user in CUMA. I have also connection to CUCM (7.1) and Presence server. CUCM is not synchronized with AD, but there is end user with the same login and password such as in AD. I added one mobile phone to my test user in CUMA (country = other, provider = other, phone model = Nokia E-series N-series and S60) with tel. number of my mobile phone 420......... .
In CUCM I registered deskphone 7911. End user has associated Remote dest. profile with one Remote destination. In this remote destination is as dest. number my phone number in the same way as in CUMA. This remote dest. is also associated with the line of my deskphone. I have also registered CUMC to CUCM with line of my deskphone.
I have deployment with ASA, but ASA doesn't have certificate signed by VeriSign. I created my own certificate and to my mobile phone I imported certificate of my certificate authority.
1 - my problem is, that CUMC in my phone is not able to connect to CUMA. There can be problem with ASA. Will I see all incoming connections to CUMA in cuma.log? I suppose, that if I will have some bad settings in my phone, I will at least see, that someone is trying to connect to CUMA and from log messages, I will be able to localize problem.
2 - in CUMA - System manag. - Network conf. - Proxy host name -> there is an outside IP address of ASA, which is accessible from Internet. We don`t have an entry in DNS yet. Can it be a problem?
3 - End users in CUCM are not synchronized with AD. Users in CUMA are taken from AD. End user in CUCM has got the same login and password such as user in AD. Is it OK?
4 - in CUCM, Cisco Unified Mobile Voice Access Service is up and running, Do I need to set up some special mobility configuration in CUCM?
5 - do I need to connect in CUCM registered CUMC and Remote dest. profile or remote destination? Remote destination is set with my mobile phone number and CUMC is registered with the primary line of my deskphone?
I hope, that if there will be some problem in configuration in CUMC, my mobile phone client will be able to log into the CUMA and I will see some error messages in cuma.log
Messages in current cuma.log are:
INFO | null - ThreadPool-Thread-389| com.orative.core.service.sip.uapool.SipConnectionPool| | | | | | inactivityTimerExpired|SipConnectionPool: Inactivity timer callback called. context is com.orative.core.service.sip.uapool.DsConnectionWrapper@1b84411
INFO | non-persistent-timer-queue-tp#6-Thread-282| com.orative.cluster.ManagedServerRegistration| | | | | | register|Registering managed server with admin server at http://localhost:7080/adminportal/registerManagedServer
I will appreciate any help because now don't know the source of my problem:(

Hi
1. While there is a way to request them, it only works if the mail recipient is using Outlook/Windows Mail to read their email, and only then if they have it turned on. Read receipts is not a standard feature of email. So I wouldn't bother.
2. Go to the Address Book, click on the group, hit Return and give it a new name.
3. You can print the whole email with attachments (if they're printable), but not attachments directly from within Mail.
4. Use the Option key to create foreign characters and symbols in any application. For example, the euro symbol is shift-option-2 (for a US keyboard). I believe option-2 might work for a UK keyboard.
5. I'm not sure what you mean by this. Can you explain in more detail?
Hope that helps!

Need info regarding tasks in ThreadPool, Executor and ExecutorService

Hi all,
I would like to know the answers for the following questions regarding tasks:
1.How do you create a self-starting task.(the task that starts executing as soon as we create runnable object)
2. how do we create a task which is executed outside the runnableObject
3. If we are executing one task in a program, how many tasks are actually running in the JVM
4. how do we know whether a task is active or not
5. what happens when a task in in wait but no one signals it
6. what happens when a task does not release the lock
7. which method is used to pause a task
8. how do we stop and restart a task
9. if three instances of a runnable class start executing in parallel, which one terminates first.
I was looking for the answers for the above question in java doc and few other sites, but was of no help.
It would be great if anyone can answer these questions. That would be lot of help.
Thanks!!

I see nothing in your questions relating to ThreadPool or Executors.
Sounds like a "homework" assignment.
First thing you need to be clearer on is what is a "task". There is no pre-defined notion of "task" in Java.
Any introductory text of multi-threading in Java will answer those questions as they apply to threads. See the FAQ for some references.

Questions on Print Quote report

Hi,
I'm fairly new to Oracle Quoting and trying to get familiar with it. I have a few questions and would appreciate if anyone answers them
1) We have a requirement to customize the Print Quote report. I searched these forums and found that this report can be defined either as a XML Publisher report or an Oracle Reports report depending on a profile option. Can you please let me know what the name of the profile option is?
2) When I select the 'Print Quote' option from the Actions drop down in the quoting page and click Submit I get the report printed and see the following URL in my browser.
http://<host>:<port>/dev60cgi/rwcgi60?PROJ03_APPS+report=/proj3/app/appltop/aso/11.5.0/reports/US/ASOPQTEL.rdf+DESTYPE=CACHE+P_TCK_ID=23731428+P_EXECUTABLE=N+P_SHOW_CHARGES=N+P_SHOW_CATG_TOT=N+P_SHOW_PRICE_ADJ=Y+P_SESSION_ID=c-RAuP8LOvdnv30grRzKqUQs:S+P_SHOW_HDR_ATTACH=N+P_SHOW_LINE_ATTACH=N+P_SHOW_HDR_SALESUPP=N+P_SHOW_LN_SALESUPP=N+TOLERANCE=0+DESFORMAT=RTF+DESNAME=Quote.rtf
Does it mean that the profile in our case is set to call the rdf since it has reference to ASOPQTEL.rdf in the above url?
3) When you click on submit button do we have something like this in the jsp code: On click call ASOPQTEL.rdf. Is the report called using a concurrent program? I want to know how the report is getting invoked?
4) If we want to customize the jsp pages can you please let me know the steps involved in making the customizations and testing them.
Thanks and Appreciate your patience

1) We have a requirement to customize the Print Quote report. I searched these forums and found that this report can be defined either as a XML Publisher report or an Oracle Reports report depending on a profile option. Can you please let me know what the name of the profile option is?
I think I posted it in one of the threads2) When I select the 'Print Quote' option from the Actions drop down in the quoting page and click Submit I get the report printed and see the following URL in my browser.

Yes, your understanding is correct.3) When you click on submit button do we have something like this in the jsp code: On click call ASOPQTEL.rdf. Is the report called using a concurrent program? I want to know how the report is getting invoked?
No, there is no conc program getting called, you can directly call a report in a browser window, Oracle reports server will execute the report and send the HTTP response to the browser.4) If we want to customize the jsp pages can you please let me know the steps involved in making the customizations and testing them.
This is detailed in many threads.Thanks

Satellite P300D-10v - Question about warranty

HI EVERYBODY
I have these overheating problems with my laptop Satellite P300D-10v.
I did everything I could do to fix it without any success..
I get the latest update of the bios from Toshiba. I cleaned my lap with compressed air first and then disassembled it all and cleaned it better.(it was really clean insight though...)
BUT unfortunately the problem still exists...
So i made a research on the internet and I found out that most of Toshiba owners have the same exactly problem with their laptop.
Well i guess this is a Toshiba bug for many years now.
Its a really nice lap, cool sound (the best in laptop ever) BUT......
So I wanted to make a question. As i am still under warranty, can i return this laptop and get my money back or change it with a different one????
If any body knows PLS let me know.
chears
Thanks in advance

Hi
I have already found you other threads.
Regarding the warranty question;
If there is something wrong with the hardware then the ASP in your country should be able to help you.
The warranty should cover every reparation or replacement.
But I read that you have disasembled the laptop at your own hand... hmmm if you have disasembled the notebook then your warrany is not valid anymore :(
I think this should be clear for you that you can lose the warrany if you disasemble the laptop!
By the way: you have to speak with the notebook dealer where you have purchased this notebook if you want to return the notebook
The Toshiba ASP can repair and fix the notebook but you will not get money from ASP.

Anyone know how to remove Overdrive books from my iphone that have been transferred from my computer? They do not show up on itunes. I see a lot of answers to this question but they all are based on being able to see the books in iTunes.

How do I remove Overdrive books from the library that were downloaded onto my computer then transferred to my iphone? The problem is that they do not show up in iTunes.
I see this question asked a lot when I google, but they always give answers that assumes you can find the books in iTunes either under the books tab, or the audio books tab or in the music. They do not show up anywhere for me. They do not remove from the app like the ones I downloaded directly onto my iphone.the related archived article does not answer it either. I even asked a guy working at an apple store and he could not help either. Anybody...?
Thanks!

there is an app called daisydisk on mac app store which will help you see exactly where the memory is focused and consumed try using that app and see which folders are using more memory
