      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content.

Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

understanding SOAP message structure

7 posts in this topic

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:main="http://main.soap.com/">   <soapenv:Header/>   <soapenv:Body>      <main:getMessage>         <arg0>abc</arg0>      </main:getMessage>   </soapenv:Body></soapenv:Envelope>

This is the SOAP request generated by soapUI for the web service I created. The webservice method looks like this :

	@Override	public String getMessage(String name) {		return "Your name is " + name;	}

What I want to ask is why does the parameter use the element <arg0> instead of <name> which is the variable name for the parameter in the method?

 

I'm using Java to generate the web service. Also, I'd like to know how to publish the webservice if I have more than one class for my service methods? I normally publish the webservice using this syntax:

Endpoint.publish("http://localhost:8080/myservice", new Webservice1());

what if I have another class called Webservice2 or Webservice3 and I want to publish it on localhost8080:/myservice too? I'll get "Address already in use".

Thanks

The names of the parameters are not important outside of the function definition. It's not necessary for the calling code to know the name that you use for the parameter, the only thing it needs to know is which parameter it is.

 

If you want to have multiple sets of functions that all respond on the same address then you'll need to make a master class that inherits from each of the other classes. You can't have any method names be the same in the different classes or that will be a problem, if it's going to work then each class needs unique methods so that it can route requests correctly. You can also change the URL to set up different web services on different URLs. Combining them into one is the same as creating one large web service, you're still not running multiple web services on one URL. A URL is a single web service, but that web service could be one which encapsulates several other services.

hi, thanks for the response. But is it possible to actually get this display in the WSDL

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:main="http://main.soap.com/">   <soapenv:Header/>   <soapenv:Body>      <main:getMessage>         <Name>abc</Name>      </main:getMessage>   </soapenv:Body></soapenv:Envelope>

if it is, could you tell me how? which code should be added or modified?

thanks

That's probably a question for someone familiar with SoapUI.

 

You can make the WSDL whatever you want. You can write that code yourself if you want to. The web service needs to be expecting it though, you need to write the web service to look at the SOAP envelope and process it a certain way. If a program like SoapUI is going to do that part for you then you're limited by whatever options the program gives you.

How do I write the WSDL? as of now, I let eclipse publish the WSDL using the Endpoint.publish command in Java. thanks

The WSDL file is just XML. You would probably want to look up the WSDL specification to see what it requires though.
