Short question about networking, Threads and web services..

Lets say I got 2 classes, Midlet A and Thread B.
I created Thread B because web services (jsr-172) uses networking and It has to be done in a separate thread other then the Midlet A.
So, in Thread B, I have the run(), where I do all my stuff, and some getSomething() methods.
I need to have run() complete before calling getSomething(), so I used something like this in Midlet A:
while(true){
if(b.isAlive())
getSomething();
}Problem is, Thread B only runs to completion when I don't call b.isAlive(). (I know from System.out.println I placed in it) When I do use any methods like wait() or join() or isAlive(), Thread B stops at the web service call.
I really don't understand what's the problem. I've tried various ways to only call getSomething() when the thread finishes running, but all of them made my WTK emulator hang at the part where it asks for permission to access the network.
If I don't use getSomething(), which is the purpose of starting the thread in the first place, it runs fine in the emulator and doesn't hang anywhere. Oh the irony.

Bump!
Anyone got even half a clue what's wrong? =O
Hmm. I think that having the midlet wait for the thread causes the midlet to hang because the thread will then wait for the midlet for permission to access the network, but the midlet is waiting for the thread to finish it's code. Damn.

Question about using threads and synchronizing objects

Hi all,
I am not that familiar and I have 2 questions.
QUESTION 1
I have a server which just sits and accepts incomming connections, then I spawn off a new thread which implements Runnable, and then call the run method. But the loop would not iterate, it would just sit inside the run method (which has rather long loop in it). I changed the class to extend Thread and called the start() method, rather than run(), and everything worked out fine.
Anyone know why this is?
QUESTION 2
So I am building a client server chat application where a user can be in multiple chat rooms. I have this personObject which has output/input streams. In the personObject, I create writeObject/ readObject method, which simply does as it implies.
I figured that I should make these methods synchronized, to ensure things run smoothly. however, when I made a call to readObject, which sat there and waited, and then made a call to writeObject, I would not enter the writeObject method. I took out the synchronized on the writeObject, and everything worked out fine.
I was under the assumption that synchronizing a method only synchronized on that method, not on the whole class. How come then was I not able to enter the writeObject method?
The more I think about it, I don't think I need to have these methods synchronized, but I thought it wouldn't hurt.
Thanks for the help.

You should still implement Runnable, rather than extending Thread. Like this: Runnable r = new MyRunnable();
Thread t = new Thread(r);
t.start(); run() is just another method. Nothing special about it as far as multithreading or anything else goes.
start() is the method that actually spawns a new thread of execution.
I was under the assumption that synchronizing a
method only synchronized on that method, not on the
whole class. How come then was I not able to enter
the writeObject method?When you synchronize, you obtain a lock. As long as you hold that lock--until you exit the sync block or call wait()--no other thread can enter that block or any other block that obtains the same lock.
Two synchronized methods on the same object rely on obtaining the same lock--there's one lock for each object.

Examples about ABAP Proxies and Web Services creation

Hi everybody.
I have been reading SAP NW PI 7.1 help about Web Service creation and sincerely, I am a bit confused. Also I have searched SDN forums, blogs and documents but my confusion persist.
I will try to depict my integration scenario below.
SLD are conformed by two machines: SAP ECC 6.0 system, client 100 and SAP PI 7.1 system, client 001.
There are two integration scenarios.
1. ABAP Client Proxy -> PI -> Web Service
I need to consume a Web Service provided by a third part. They provided me with WSDL files and I imported them into ESR. I already construted all other objects (data types, message types, etc.). In the examples I found I cann't see what to do with those definitions, I don't find any suitable example. This is an asynchronous scenario. The Web Service will be consumed from SAP ECC 6.0 system through an ABAP Cliente Proxy.
2. Web Service -> PI -> ABAP Server Proxy
I need to provide a Web Service for others to consume it. I already have created the WSDL for Service Interface I created in ESR using the respective wizard in Integration Builder. This is an asynchronous scenario. The Web Service will be consumed by others outside landscape configuration. When the Web Service is consumed must run an ABAP Server Proxy.
In spite of my investigation about Web Services building in SAP NW PI 7.1 I cann't finish my work successfully.
I just need a good example, any suitable example for each integration scenario.
Thanks in advance.
Rafael Rojas.

Hi,
1. ABAP Client Proxy -> PI -> Web Service
1. Create all necessary objects in ESR
2. Create integration scenario objects with PROXY as sender SOAP or WS adapter as receiver
3. Create client proxy in your SAP backend using SPROXY
4. Create ABAP client proxy to execute the proxy which then will call your PI runtime to execute the webservice.
2. Web Service -> PI -> ABAP Server Proxy
1. Create your necessary objects in ESR
2. Generate server proxy in your back end system
3. Create integration scenario objects with PROXY as receiver and SOAP or WS adapter as sender
4. Generate WSDL from integration scenario and pass it to your partner.
You can find many blogs which discuss these steps in more detail.

Newbie question about the viability of web services.

Hello All,
I have never dealt with web services, and have only cursory knowledge of the technology, so forgive my ignorance in advance.
I have a situation that I wonder if Web Services might help me solve.
I have built a Java/JSP application that resides on a server that is inside our firewall. It has been successful, and management wants to make the data and functionality available to our customers outside the firewall.
The problem is that our organization tightly controls the "public" applications. And the UI for my system does not meet their standards. Nor will they punch a hole in the firewall to allow access to my server.
The solution we have been working on is to create a new UI using their approved methods, and copy the needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain two instances of the same class on two different servers.
Can I avoid this by using web services to make those classes available to other applications from my internal server?
Thanks in advance for your help.
James.

The solution we have been working on is to create a
new UI using their approved methods, and copy the
needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain
two instances of the same class on two different
servers. Okay, first, yes - webservices can help you if you MUST maintain two seperate UI's for some reason using the same backend data code or if you want to provide a datafeed only to your external users. It will take care of having to maintain seperate but identical class files, but it will create other overhead such as interfacing the existing files and the like, but if you must enable the UI then you will have two versions of this to maintain. If you are looking to just enable the data feeds and not the UI then it would seem a very logical fit.
If you must maintain the UI, then why can't you convert your app over to the approved UI and host it on the "public" server for all users (internal and external)? Then you only have one set of data to maintain - period and webservices aren't necessary. If you proceed with either your current implementation or even with a webservices based implementation, you will have at least two seperate UI's to maintain as well as whatever the resulting support code - be it webservice interfaces to existing code or replicates of existing code - to also maintain.

Question about the distribution of web service or servlet

Hello,
I don not know how to distribute a web servcie or servlet on the web server. I can only use this web service with the open state of the glassfish. If I close the glassfish server, the servlet cannot be accessed.
I just want the web service or the servlet to be disributed on the web server. Web service and the servlet are available when the web server is on.
anybody can help me?
thank you in advance.

Question about network simlocks and countries

No, I'm not asking how to unlock the phone, as that would be unethical. (Whether or not it is illegal is an interesting question, but not one I'm prepared to venture into here.)
A friend of mine has a phone that is simlocked to Orange in the UK, and I'm contemplating buying it from him.
However, even though I'm with Orange, I live in Switzerland.
Will a phone simlocked to Orange(UK) work with Orange(CH)?

The simlock information stored in the usually specifies network operator and country. The phone may ignore the country setting if the operator information is correct but I wouldn't bet on it!

Question About Java Threads and Blocking

I'm helping someone rehost a tool from the PC to the Sun. We're using the Netbeans IDE and the Java programming language. I took a Java course several years ago, but need some help with something now. We're developing a front-end GUI using Swing to allow users to select different options to perform their tasks. I have a general question that will apply to all cases where we run an external process from the GUI. We have a "CommandProcessor" class that will call an external process using the "ProcessBuilder" class. I'm including the snippet of code below where this happens. We pass in a string which is the command we want to run. We also instantiate a class called "StreamGobbler" my coworker got off the Internet for redirecting I/O to a message window. I'm also including the "StreamGobbler" class below for reference. Here's the "CommandProcessor" class:
// Test ProcessBuilder
public class CommandProcessor {
public static void Run(String[] cmd) throws Exception {
System.out.println("inside CommandProcessor.Run function...");
Process p = new ProcessBuilder(cmd).start();
StreamGobbler s1 = new StreamGobbler("stdin", p.getInputStream());
StreamGobbler s2 = new StreamGobbler("stderr", p.getErrorStream());
s1.start();
s2.start();
//p.waitFor();
System.out.println("Process Returned");
Here's the "StreamGobbler" class:
import java.lang.*;
import java.io.*;
// Attempt to make the output of the process go to the message window
// as it is produced rather that waiting for the process to finish
public class StreamGobbler implements Runnable {
String name;
InputStream is;
Thread thread;
public StreamGobbler (String name, InputStream is){
this.name = name;
this.is = is;
public void start(){
thread = new Thread (this);
thread.start();
public void run(){
try{
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
while (true){
String s = br.readLine();
if (s == null) break;
System.out.println(s);
//messageWindow.writeToMessageArea("[" + name + "]" + s);
is.close();
catch(Exception ex){
System.out.println("Problem reading stream" + name + "...:" + ex);
ex.printStackTrace();
The "CommandProcessor" class calls two (2) instances of the "StreamGobbler" class, one for "stdin" and one for "stderr". My coworker discovered these are the 2 I/O descriptors that are needed for the external command we're running in this case. We're actually called the Concurrent Versions System (cvs) command from the GUI. Here's what we need it to do:
We want to display the output real-time as the external process is executing, but we want to block any actions being performed on the GUI itself until the process finishes. In other words, we want to show the user any generated output from the process, but don't want to alllow them to perform any other actions on the GUI until this process has finished. If we use the "waitFor()" function associated with a process, it blocks all external process output until the process has completed and then spews all the output to the screen all at once. That's NOT what we want. Also, if we don't use the "waitFor()" function, the code just continues on as it should, but we don't know how to block any actions on the GUI until this process has finished. My coworker tried the following code, but it also blocked any output until the process had finished:
while (s1.thread.isAlive() || s2.thread.isAlive())
// We really don't do anything here
I'm pretty sure we have to use threads for the output, but how do we instantly show all output and block any GUI actions?
Thank you in advance for your help!

You're talking about a GUI, but there's nothing in that code which is putting events into the GUI update thread. You also say that nothing happens to the GUI until the CommandProcessor.Run() method returns if you wait for the process.
This implies that you're calling CommandProcessor.Run() in an ActionListener. This will block the GUI thread until it completes.
I was going to explain what to do, but a quick Google informed me that there's a new class which is designed to help in these situations SwingWorker (or as a [separate library|https://swingworker.dev.java.net/] if you're not up-to-date yet).

Question about networking iMac and streaming video to TV

I have the 24" iMac 2.66GHz with 4 G ram. Currently using Motorola SBG900 (Docsis 2) cable modem & router to stream Comcast through house (another PC, iPhones, LG Blu Ray player/digital video streamer).
Recently acquired a Netgear Rangemax 3700 which is supposed to be the fastest current wireless router. Here are my questions:
1) Can I just use the Motorola SBG900 as modem ONLY and run the ethernet out of it to the Netgear router (thus bypassing the router built into the SBG900). Will this accelerate the streaming of video to other receivers?
2) Would I be better off with a Motorola 6120 Docsis 3 Cable modem feeding the Netgear router (even though my Comcast cable feed is Docsis 2, not 3)?
3) Since my Comcast account is rated 10 Mbps max (though it sometimes goes up to 15 or so late at night) and I believe the existing Motorola SBG90 is rated at 54 Mbps, is the limiting factor the speed of my Comcast connection and all else doesn't matter? That is, is it impossible to speed up my streaming or download speed without a faster connection to the Internet?
4) What kinds of connections are there that are faster than Comcast cable connections?
Basically, I don't want to waste money or time if I'm already at the maximum throughput available given my connection. If I can get marginal speed increases by adding new modem and router, that's fine. I'll do that.
Thanks for your help.
PS: I owned and returned the Airport Extreme Base Station. It did not increase the speed of my connection or streaming, but then it tested very poorly at www.smallnetbuilder.com -- about half the speed of the Netgear Rangemax.

Can't help with Q 1 + 2, but here are some things to consider re:
+3) Since my Comcast account is rated 10 Mbps max (though it sometimes goes up to 15 or so late at night) and I believe the existing Motorola SBG90 is rated at 54 Mbps, is the limiting factor the speed of my Comcast connection and all else doesn't matter? That is, is it impossible to speed up my streaming or download speed without a faster connection to the Internet?+
My Comcast account is rated 15 Mbps and I never get that. I've done everything I can here including Cat 6 cables (instead of Cat 5), but the major problem/hangup in my case is: Comcast is using 20-year old buried cables from their hub (approx. 10 mi across town) to the neighborhoods here - those cables are "leftovers" from the company Comcast purchased the rights from. So, we not only have old cables, but the little boxes all over the neighborhood feed at least 6 - 10 homes each, so you are sharing the available bandwidth with the neighbors. And, whenever everyone seems to be online at the same time, my downloads slow down to a c r a w l (as slow or slower than dialup occasionally!).
So, unless you have a better/newer cable setup where you are, you need to keep that in mind; in that case, no matter what you do, you are at the mercy of Comcast's equipment and your neighbors' usage.
4) The only one I know of is FioS (fiber optic).

SSL certificates and Web Services Usage inside Oracle Database Questions!

We have implemented a specific business logic using PL/SQL for our client, so we open a file and process each line of this, doing something in the Database and also call a Web Services (Service1) using UTL_HTTP package. Service1 runs in a Windows 2008 Server in the DMZ as Database server.
Service1 is already working, and we can call the service from PL/SQL without troubles.
However, according with security client's policies they requires all Web services be consumed via https including Service1, so we must to follow the procedure established for Oracle in order to enable the calling of service1 via https from the Database.
Our client's DBA and IT Team are concerned about two subjects before to continue to follow the certificate installation:
     - SSL Certificates:
1- Can installed certificates in the Database put in risk the stability of the database?
          2- Can installed certificates in the Database generate performance issues?
          3- Can installed certificates reloading the Databases?
          2- Can installed certificates in the Database generate security issues?
     - Web services:
1- Can web services calling from the Database put in risk the stability of the database?
2- Can web services calling from the Database generate performance issues?
3- Can web services calling from the Database generate security issues in the DMZ?
Could you please give us any clues, about the possible negative impact related with the SSL certificates and Web Services Usage inside Oracle Database, if it’s the case this impact exists?.
Those are the links describing the procedure mentioned above.

Thiago:
You are correct in that there should be no problem interacting with a Web service that has an HTTPS endpoint as long as you create a wallet and specify it when you make your UTL_HTTP calls, like the PayPal example.
I am not aware of a PL/SQL utility to create a XMLDsig Standard message, but if you find some Java source out there that does it, you may be able to follow a technique I used for a similar use case:

Different versions of JDeveloper for client and web service

Hi,
Here is a tricky question: I've created a web service using JDeveloper 10.1.3.3 and I want to generate a client from the corresponding wsdl. The thing is however that the client will reside on Oracle Application Server 10.1.3.0 so I have to generate it from JDev 10.1.3.0.
I first tested to generate a client in JDev 10.1.3.3 and it worked fine sending messages from my local machine. But then I tried to generate a web service proxy in JDev 10.1.3.0 and in the last step when pressing the finish-button I get the following error:

Messages Monitoring and Web Services Sequences .... SOAMANAGER

When can I use Mesage Monitoring and Sequence Monitoring .
We are making a proof a concept and we are the following.
1. A program which executes a proxy and with this proxy we are consuming a web services.
2. The proxy and web services were implemented in the same Abap Machine .
3. We execute the test and everything works very well and we consume the webservice and the program displays the expected result.
Now want to know How can we use the Message Monitoring and the Sequence Monitoring . Is this posible ? Do we have to make any previous configuration?
We don´t have any XI installation and for that we wonder if we can monitorize the webservices sequences ?
Any idea about if we can realize such king of actions ..
Many Thanks

hi,
short answer: you can't. to my knowledge there is no such thing as message/sequence monitoring outside of PI/XI.
the only thing you can do is to enable debugging and access some debugging info from ST22. other than that you do not have access to the original (XML) message, the HTTP headers or the ST(simple transformation) info or anything else.

The Oracle Database Programming using Java and Web services book is out

This book http://www.amazon.com/gp/product/1555583296 shows how to build pragmatic applications using the combination of PL/SQL, Java in the database, JDBC, SQLJ, JPublisher, and Web services. It is intented for database developers, DBA, data architects, Java developers and Web services assemblers.
My blog http://db360.blogspot.com/ and the free/sample chapter http://www.oracle.com/technology/books/pdfs/mensah_ch1.pdf will give you a feel of the content.
Enjoy, Kuassi

Hi Kuassi,
Thanks for letting us know that your book is available. I have been following one of your articles about "Virtualize Your Oracle Database with Web Services". More specifically "The Database as Web Services Consumer". I think that this is an area that has in the past been under estimated as to the potential benefits.
I am currently trying to develop a solution that consumes several interfaces with a couple of them being published web services, so an ideal solution. I have then spent the last three weeks having to read up about the architecture of Java in the database, Jpublisher and make sense of how it all works together.
I have got very close to getting one of the web services to work but failed due to using 10gR2 where all the java & libraries has moved to version 1.5. The solution is to load the jdk1.4.2 and configure jpublisher to use this. So far so good except this is not available on some platforms, Windows - 64 bit (not itanium).
The configuration is proving very challenging but will hopefully reap rewards.
(Thought I would give you some background to my experience).
Anyway my question to you is having looked at Jdeveloper it appears to do almost anything except consume services into the database, also with Java now being at version 1.5 outside the database for 10gR2 and supporting 1.4 inside, do you see some alignment of these in future database releases?
Finally off to buy your book now as no doubt there is a huge amount more to learn.
Kind Regards

Requirement to have email and web service.

I have Verizon wireless and they are telling me that I am required to have the email and web service on the Blackberry and I was also told that I needed for the operation of the phone to operate as a regular phone. Is this true? I wanted them to take off the email and web service until I could get another job because I can't afford the 30.00 dollars per month but sill have the phone use as a regular phone. I was wondering if it is Blackberry or Verizon that is requiring this.

It is Verizon requiring that. You are using their network, and they have a right to require what they wish while you use their network.

XML and Web Service Data Source Missing in Crystal Reports for VS

I would like to use a Web Service as the data source for a Crystal Report that will be running outside of my Visual Studio application. So setting the data source to the web service in code is not possible. My understanding is Crystal Reports has a connection (in the Database Expert under New Connection) named XML and Web Service. Here you can select web service and enter the WSDL URL for the web service. However it does not appear in the list for Crystal Reports for Visual Studio. Does this connection type come with the Visual Studio version of Crystal Reports and if not is their a way to obtain it?
Thank you for your assistance.

None of the bundled versions of CR have the driver. Reason is that the driver responsible for these connections requires the Java framework and I suspect MS would not be too pleased if we installed the Java framework. The stand alone versions, since they are not part of any bundle can and do install the Java framework and the driver. Note that even the latest release of CR - CRVS2010 does not have the driver as it essentially becomes a bundle or a VS2010 plug-in.
So, the short of it is; you have to obtain a stand-alone version of CR. I'd recommend CR 2008 (12.x) as CRXI R2 will run out of support in June of this year.
