How do I ping a URL in Java?

All I wanna do it ping a URL. Can I do it? Like, have the user input a URL, then make the URL object, then ping it, then display the results. Can I do this?

do you mean 'ping' in the traditional sense of computers finding the time delay in communication between them? Or do you really just wanna find out if theres a server listening on a certain URL/port? The only way I know how to find a time delay is to make a client/server so you'd have to have access to both machines, or perhaps use the ping protocol but I believe that is limited to Unix boxes? Or if you'd rather just findout if there's a server listening at a particular URL you can just create a Socket for the url/host and if it throws an exception you know theres nothing listening on the other side.

How to know the logout url in Java PDK

Is there any method that can give us the logout url of SSO using java PDK?
Thanks in advance,
Tony Cruz

Thank you for the replies. But what i really want to do is a login portlet that can show me a link to logout, and i want to use this portlet in all projects that my company is in, so the code of this portlet must be 100% dinamic, this means that i do not have to know the database schema/passwords, where database is, etc, i thought there was some method in the JPDK that was able to give the link to logout (this is possible for login) but until now i cannot find it. There is a solution for this using a PL/SQL procedure called wwsec_app_priv.logout that lies in the portal schema, this procedure works but i'm not able to redirect the browser to the url i want after logout (in the documentation they say its possible and that there is a parameter called p_done_url that can do this, but in the procedure signature this parameter its not implemented) so right now i'm stucked in this one, and im not sure if i can use the 100% dynamic approach with good results.
Thanks

How to get SEO url in java

Hi
My requirement is to generate a product feed which has its product url as one of the fields.
Now does anybody know how to get the SEO url of a product in a java file.
I know form front end we generate it via ItemLinkDroplet.
But is there a way i can generate it in my java class?
Thanks

Assuming you have used ATG SEO Repository and ATG DirectUrlTemplate and IndirectUrlTemplate etc..for SEO URL generation.
Now, create a standalone jsp, example, seolinkbuilder.jsp.
Let it take following parameters,
productId
categoryId
brandId
siteId
and any other ids as needed by your application.
Suppose you just needed SEO url for a given product id.
/contextpath/seolinkbuilder.jsp?productId=12345
The JSP would contain a droplet which would construct a SEO url and set it as oparam which can be written to JSP.
Finally, from an independent JAVA program, using Apache HTTPClient API, call seolunkbuilder.jsp by passing productId. Read the response for SEO url.
Let me know if you have further questions.

dose any one have any clue what should i do to get respond for sending this sms?

soudshoja wrote:
i tried applying it directly into browser did not work, I thought you said it did work. The reason is that browser a lot of the time will apply URL encoding on things manually entered.
and about ( URL encode the parameter values before concatenating them into the URL. ) i dont get what u mean can you be specific?Check java.net.URLEncoder Only specific characters are allowed in a URL, other characters need to be encoded/escaped using a process called URL encoding

How to access .asmx Web Service using JAVA? Newbie

Hello Experts,
Currently, I have a project where in I have to access a ,NET web service. It is made of C#. I just want to ask how will I start the accessing process? I made this simple equation on how my project is.
Java Project + C#.Net Web Service = Integration
1. Do i need to create a Web Service too for the Java Project? If yes, What are the necessary tools needed for the creation of this Java Web Service?
2. The .NET Web Service is available online. (It is made by other people).
3. Based on the equation, what is the equivalent technology for the + sign?
4. Can you site a concrete example for accessing a web service?
5. I'm new here. Totally I have no idea where to start.
6. Thank you experts.

Hello
Thanks a lot for your help ...
I am developing simple J2EE based web service client using IBM WSAD 5.1. I have used the following code to call .asmx web service in Java
String url = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
     String namespace = "http://tempuri.org/";
     name = request.getParameter("txtName");
     try
          System.out.println("In Internet Service");
          ServiceFactory factory = ServiceFactory.newInstance();
          Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
          System.out.println("Got Service......");
          Call obj = (Call)serv.createCall();
          System.out.println("Got Call......");
          obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
          obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
          obj.setTargetEndpointAddress(url);
          obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
          obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
          obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
          obj.setReturnType(XMLType.XSD_STRING);
          System.out.println("Parameters Set.....");
          Object[] params = new Object[]{name};
          k = (String)obj.invoke(params);
          System.out.println("Result: "+k);
     catch(Exception e)
        System.out.println("Exception is : "+e);
    }But this code is throwing exception that

How can i execute Spaces API in java main class?

Hi
I am able to execute Spaces API through portal application. However if i try to execute it in java main class, its throwing an exception
"SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)"
oracle.wsm.common.sdk.WSMException: WSM-00145 : Keystore location or path can not be null or empty; it must be configured through JPS configuration or policy configuration override.
How can i set this path, so that i can execute Spaces API from java main class.
Need this main class to configure in cron job, to schedule a task.
Regards

Hi Daniel
Currently i have implemented create functionality in my portal application using Spaces API, which is working fine. Now the requirement is, i need to implement a "Cron Job" to schedule a task, which will execute to create space(for example once in a week). Cron job will execute only the main method. So I have created java main class, in which I have used Spaces API to perform create space operation. Then it was giving exception.
Later I understood the reason, as I am executing the Space API with a simple JSE client, its failing since a simple java program has no idea of default-keystore.jks, jps-config.xml, Security Policy. Hence i have included those details in main class. Now I am getting new error,
SEVERE: WSM-06303 The method "registerListener" was not called with required permission "oracle.wsm.policyaccess"
For your reference i have attached the code below, please help. How can i use Spaces API in java main method(i mean public static void main(String[] args) by giving all required information.
    public static void main(String[] args) throws InstantiationException,

How to import a tcl package in Java

Hi,
I want to convert an existing tcl file into a java source file. In my existing tcl file, some tcl packages have been imported, using the syntax
package requires XML
where "XML" is the name of a tcl package.
But I am not sure how to import this tcl package in my Java code. Also, how can i call tcl procedures from Java code. The tcl package file contains a set of tcl procedures.
Please let me know that
1> How can I import/call a tcl package in a Java code.
2> How can I call a tcl procedure in a Java code. The tcl procedure is contained in the tcl package file.

I have searched the url provided by you. But I couldn't find anything relevant to my requirements.
They have basically explained about how to call a Java program from a tcl code using java::call command
But they haven't provided anything related to importing tcl package files inside java source.
Please let me know your opinion on this issue.

How to configure a JNDI URL resource

I am trying to replicate the Websphere's URL Resource provider functionality in Tomcat, but haven't been really successful. So what I would like to do is access a properties file from a URL. This provides a convenient approach to modifying prop files as apposed to residing within WAR file. Anyway back to my question, I have taken a stab at this and below is how my meta-inf\context.xml, web.xml, and jndi code snippet looks.
CONTEXT.XML
code:
<?xml version="1.0" encoding="UTF-8"?><Context> <Resource name="url/wfresource" auth="Container" type="java.net.URL" url="http://localhost:8080/ibi_html/wfresource.properties"/></Context>
WEB.XML
code:
<resource-env-ref> <description>Object factory for MyBean instances.</description> <resource-env-ref-name>url/wfresource</resource-env-ref-name> <resource-env-ref-type>java.net.URL</resource-env-ref-type> </resource-env-ref>
JNDI Lookup code snippet
code:
//Get a handle to the JNDI environment naming contextContext env = (Context)new InitialContext().lookup("java:comp/env");//Get a single valuejava.net.URL destURL = (java.net.URL)env.lookup("url/wfresource");
Its throwing an exception.
My question is if URL resource configuration is possible in Tomcat 5.5, and if so how.
thanks

Problem solved in the original thread. If you are trying to do the same be sure to check it out (the SUN documentation is faulty):

I apologize for starting two threads on this.

How can I build Instalation Program for java applet?

I want to build on line internet game based on java applet.
Uset must instull the game to his computer.And this program mast Connect to the server when user enter
to this application.Not from explorer,but from my application,like when i enter to ICQ.
My questions:
How can i build instalation program in java?
How can i connect to the server when user enter into my game not from explorer but from game?
Thanks,Maya.

Hi Maya
First of all an Applet does not have to be "installed" as you would with a normal application. The browser handles the install and execution of the applet.
Check out this URL for more about applets:
http://web2.java.sun.com/docs/books/tutorial/applet/index.html
On the subject client/server pairs - see:
http://web2.java.sun.com/docs/books/tutorial/networking/sockets/index.html
If you decide to make the game an application instead check out Sun's WebStart - under the products section.
That's about all the help I can give you.
Programming a game is a complicated subject - I am doing one too:

How can i get the result of java class to InputText Or OutputText ???Can you elaborate on your requirement? Do you mean the return value of a method in a class as output text? Or an attribute in your class (bean?) as text field?

Hi Mohan,
You need an account for the ES Workplace. I'm afraid this is not free, e.g. check [SAP NetWeaver, Composition Subscription|https://www.sdn.sap.com/irj/sdn/subscriptions/composition].
But I thought you wanted to play with a WSDL [you already had at hand|Sample code to access BAPI Web services from JAVA required;?
