DW CC 2014, writing web services

Web Services has been deprecated in DW for some time now. What solutions have been introduced or deployed to help development of web services consumption in the DW environment? Are there any extensions, tools, or other services that allow for integration of web services into my DW projects?

Web Services is a very broad term that, as a whole, barely describes any of the features that Dreamweaver has or had. Presumably, you are referring to the database connectivity and the associated Behaviours panel.
The closest match that I can come up with can be found here MySQLi Server Behaviors | Dreamweaver extension | WebAssist.
The Data Bindings extensions found here http://www.dmxzone.com/search.asp?searchString=data+bindings&STypeId=3&action=Search perform a similar task, but on a different footing, namely more Ajax orientated.

What's a lightweight method to call a web service from an applet?

So, writing web service clients in java is pretty easy these days using the JAX-RPC library. Problem is in an applet you want it to load fast. I need my applet to call a web service, but don't want to include all the 'baggage' that comes along with JAX-RPC. It looks like you need XML libraries for JAX-RPC stuff to run, and those are huge jar files (many megabytes). I want a lightweight way to call web services. They are my own web services, so I don't need a general solution. There's got to be a way to just form a soap message and use http to send it. It seems like that has been done already.
On a related note. I will be passing byte arrays as parameters, so if I do try and form my own SOAP XML message, how are byte typically encoded into these messages?
Thanks a bunch for any suggestions.
Mike

The scripting prompt is due to locally installed WebHelp. If you put it on a server, it should work fine. (Or try to enable Mark of the Web for your output.)
The problem with CSH not working is probably because the CSH is not enabled in the output. In the single source layout settings, make sure that all your map files are selected:
The easiest way I see it to create a simple API yourself. (We did it for Delphi and C# and it took about ten minutes.) You can just create a URL and feed it to the default browser. If you want to be able to load new help calls in the same tab, you will have to hook into the browser somehow.
The URL's are really easy to create. See http://www.wvanweelden.eu/article-category/context-sensitivity for a complete overview of all your options in HTML and WebHelp. If you want to call a CHM context sensitive look at the following article: http://msdn.microsoft.com/en-us/library/2bk8zwb3(v=vs.90).aspx

How to add image in ejb web service

Hello Community,
I am writing web service to create a PDF file using itext API. In PDF file i want to add an image.
Can someone please tell that , how can i add image(jpeg, png , etc.) to an ejb web service?
Thanks in advance
Regards,
Dishant Chawla

Hi,
Please check the below code which i used to add image to the header using iText . Similarly you can add image directly to the document also as a element.
Adding image as Header:
httpServletRequest = request.getServletRequest();
domainURL=httpServletRequest.getScheme()+"://"+httpServletRequest.getServerName();
imgLogo=domainURL+request.getWebResourcePath()+"/images/XXXX.jpg";
image =Image.getInstance(imgLogo);
image.scalePercent(22);// As per you need
chunk = new Chunk(image, 0, -20);
HeaderFooter header_pdf = new HeaderFooter(new Phrase(chunk), false); // here i have added image as header
header_pdf.disableBorderSide(0);
header_pdf.setAlignment(Element.ALIGN_CENTER);
header_pdf.setBorder(0);
document.setHeader(header_pdf);
(or)
Adding Image a Element:
httpServletRequest = request.getServletRequest();
domainURL=httpServletRequest.getScheme()+"://"+httpServletRequest.getServerName();
imgLogo=domainURL+request.getWebResourcePath()+"/images/XXXX.jpg";
image =Image.getInstance(imgLogo);
image.scalePercent(22);
document.add(image);

Web Services using Java 6

Hi,
Well, I've been very enthusiastic in implementing a new application that's taking advantage of the newly introduced technology that Java 6 has to offer, instant web services that is. I've implemented the web services and was also able to launch the internal server that comes with the JDK. I must admit that life became really easy due to those introduced technologies, it saved me a lot of time. Furthermore, now I've reached a point where an application I'm integrating with needs to call my server by invoking a simple http request, however, since my server only provides web services I'm kind of stuck and can't think of an easy (fast) solution... I wouldn't like returning to the frustrating old days where I had to use Tomcat and also Axis in order to support both of these functionalities... the question is whether there is a simple way to also expose a simple servlet by using the internal Java 6 server or maybe there is a way to expose a webservice that is actually a servlet...
your answers are very appreciated :)
thanks,
Gil.

Hi,
well, I've taken your advice seriously and immediately turned into embedding Jetty into my application...
However, due to the fact that I'm a newbie to both Jetty and Web Services I have gotten to a point where I no longer manage to continue :-(
In order to enable web services I've followed this guideline ([http://gorik.wordpress.com/2008/03/15/jax-ws-and-jetty/]), however, it seems to mislead in some points or at least lacks some vital information I suppose...
I could not successfully access my webservice even after doing the following actions:
1 - Writing web service source code and using webservice annotations.
2 - Successfully generating wsdl and xsd files
3 - Successfully running Jetty server
4 - created folders under jetty\webapps\ : myApplication\WEB-INF, myApplication\wsdl
5 - copied jar file holding the webservice into WEB-INF lib, copied the wsdl under the wsdl lib
6 - created a web.xml file under myApplication with the following content:
<web-app version="2.4? mlns="http://java.sun.com/xml/ns/j2ee" xsi:schemalocation="http://java.sun.com/xml/ns/j2ee [http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd]">
<description>fromwsdl</description>
<display-name>fromwsdl</display-name></web-app>
<listener>
<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class></listener> <servlet>
<description>JAX-WS endpoint - fromwsdl</description>
<display-name>fromwsdl</display-name>
<servlet-name>WebServices</servlet-name>
<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>WebServices</servlet-name>
<url-pattern>/NadlanWebServices</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>60</session-timeout>
</session-config>
{code}
and what happens when I launch Jetty server is that it claims that it cannot find index.jsp file which is the file that's configured in jetty/etc/webdefault.xml,
though clearly, it should have not looked for this file due to the servlet mapping I've configured in the web.xml that appears above...
please help ....

Forms 10g, OAS and Web Services.... help!

Hello,
We're in the middle of a project that was originally supposed to be a (simple :D) upgrade of an existing Forms 6i application to a Forms 10g application.
During the course of the project we have encountered various problems with the older forms (shakes fist at Headstart code...) and as a side effect have had to upgrade our OAS to 10.1.2.0 (10gR2). That's fine, however we have recently been looking into replacing the C++ code that the old application uses to connect to SAP with a new Web Services system, using the SAP Adapter and WSDLs and BPEL and all the rest of it (steep learning curve).
In setting that up it seems it would be advisable for us to upgrade to 10.1.3.x (or "get a headache" said Oracle Support...) However, I now read (in an article from July last year) that Forms and Reports are not supported in 10.1.3.x...
So, do we ask our DBAs to go ahead and install the SOA suite 10.1.3.x? And if so, do I need to do something else to support our !0gR2 forms? Or will they just work? Can we do a "clean" install of 10.1.3.x or do we upgrade the existing 10.1.2.0 system....? Colour me confused.
Help!
Thanks in advance
Dan

You are correct, Forms 10gR2 is the latest and is not available on the 10.1.3 stack. I am also not sure if you are talking about writing web services or just consuming them. However you have 2 main options.
you can install 10.1.2 and use 10.1.2 for Forms and use 10.1.2 for your web services - this should work ok but of course you are "handicapped" by only being able to use 10.1.2 features of BPEL and WS.
Next option, you can install 10.1.2 for running Forms and run a separate 10.1.3 for running BPEL and SOA suite - nothing wrong with that. And if you write a web service and deploy to 10.1.3 you can call that from Forms.
Example of calling an external web service from Forms

http://www.oracle.com/technology/products/forms/forms_modernization.html - calling a BPEL process is just like calling a web services

Using JBoss for web services

hi,
I have to do an academic project that invovles writing web services to interoperate between a .NET client wriiten in C# with server side logic written with EJB 2.0. Initially, i was inclined to use WebLogic, but i wonder if JBoss along with the Jetty Web Server is a good alternative to WebLogic.
Could some pls help me in this regard
regards,
vishwak

It is free and it performs as well as weblogic. For an academic project, it will be a good choice.
Use other Open Source tools for your Web Service development and stay away from any vendor specific WS implementation.
Good Luck

2014 web service in cRIO build

I have labview 2014 and a crio 9023. In the developer mode I can run the rt.exe and the developer mode web service that sits on the crio. Then I can have my pc app talk to the server. All three programs work together, but then I make a build......
Question 1
In the web services dialog I check my server, configure the ports, but then I need to look for the ssl certificate. Since I'm using labview's generated ssl cert on the crio, I enter the cio name/ip address to query the for the ssl certificate but none are found. Something I'm missing here? So I just enter the path in the box provided to the ssl certificate on the crio c:\ni-rt\system\niwebcer\server_certs\server_0.cer and proceed.
Question 2
I build and deploy. The crio is running indicated by the user led on the controller. I also put RT Debug String in my server startup application so that every 2 seconds the startup vi outputs the time of the last update from the rt.exe. So now I know my server is running. But this server does not show up in the web based - web server configuration page? Is the web server config page for standalone servers only or should I see my integrated server that is tied to my build?
Question 3
I change the webserver port that my pc app is directed to, and run the program. Unfortunately the server is not found. If I use the "show URL" button in the project, copy that url into explorer, I still get a server not found. Do the paths change for a build besides the port? Do I need to include my server method VI's in the build?
Thanks

Got somewhere:
1. I leave that blank and let the crio use the "default" what ever that is. I can not get the the it to query and find the certificate. Couldn't resolve this question.
2. That page seems to be for standalone servers only. A unique server tied to the application does not appear here.
3. The ports I selected in the web services page of the build were already taken by the system/application web servers.

Help me in writing client for this JAX ws Web service

Hi ,
I am unable to write client for my Webservice deployed under glass fish v3 .please help.
package jws;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebParam;
@WebService(name="CalculatorPortType")
public interface Calculator {
    @WebMethod
    public int add(int value1, int value2);
} package jws;
import javax.jws.WebService;
@WebService(serviceName = "Calculator",
            portName="CalculatorPort",
            endpointInterface = "jws.Calculator")
public class CalculatorService implements Calculator {
    public int add(int value1, int value2)
         System.out.println("Inside web service class ");
        return value1 + value2;
My client which is incomplete :please help
import java.net.URL;
import jws.CalculatorService;
import jws.Calculator;
import javax.xml.ws.Service;
import sun.print.resources.serviceui;
public class Hi {
@WebServiceRef(wsdlLocation=
"http://localhost:8089/Ram/Calculator?wsdl")
CalculatorService service ;
public static void main(String argsp[]) throws Exception
} This is deployed under glassfish v3.

When you just use the JAX-WS standard you do not need any WebLogic related classes to create a client for your web service.
When the web service is deployed the WSDL can be accessed. By using this WSDL you can create your client by using tools
such as wsimport (which comes with a JDK distribution and is located in the JDK_HOME/bin directory)
wsimport -keep -d C:\YOUR_PROJECT\src http://hostname:port/context/SomeWebService?wsdlthe 'keep' option make sure the generated .java files are not thrown away.

Need help writing client for WSE 1.0 Web Service

Hello all,
I am attempting to write Java clients against a .Net service that uses WSE 1.0. I can't seem to get any of toolkits I have tried to work with this service. Unfounately, I do not own the service, so I cannot upgrade it to WSE 2.0. The problem seems to be that the WSE 1.0 expects namespaces from the July 2002 version of WS-Security, while all the libraries I have tried (JWSDP, Oracle Web Service Wizard, etc) use the oasis namepsace from January 2004.
Can he one suggest an alternative? Is there a way to set the namespace sent in XWS-Security? I think this might solve the problem...
Thanks,
KS

Hi,
firstly JWSDP 1.5 is pretty old, the latest release of JWSDP is JWSDP 2.0 that happened late last year.
The problem is most likely happening due to a bug in JWSDP 1.5. If you dump the Message that is going over the wire you will probably see
SOAPAction : ""
SOAPAction : "<the correct action value>"
And this is the reason for the failure. I believe you are using SOAP 1.1 messages right ?
What you will need to do is upgrade to
JWSDP 2.0 and more important also upgrade your SAAJ jars in the JWSDP installation to SAAJ 1.3
https://saaj.dev.java.net/files/documents/52/32730/saaj1.3.zip
Alternatively, you can use Sun's Project Tango (Sun's Next Generation WebServices Interoperability Technology Offering) which has been tested to interoperate with Microsoft WCF.
http://java.sun.com/developer/technicalArticles/glassfish/ProjectTango/
You can download Project Tango by visiting the following page :
https://wsit.dev.java.net/
Look at the Try It section for instructions on how to use it.
Using the Netbeans Plugin you can develop a java client which can securely communicate with the .Net WebService. All you need to do for that is use Netbeans to create a Java WebService Client by pointing it to the WSDL of the .Net Service.
Let us know if this helped.
Thanks...

Problem in writing a client web service from WSDL document

Hi,
I wrote a web service using .Net and a WSDL document. I tried after that to generate a client web service using Jdeveloper. but, the methode generated by Jdeveloper (in the stub) does not represente the original methode.
<?xml version = '1.0' encoding = 'windows-1252'?>


<definitions

</definitions>
Here The methode Validate consume two parameters : string and long
the generated stub look like :
public Vector Validate(Element requestElem) throws Exception
There is some one who have a solution ?
---------------------------------------

My guess is that it is because .NET defaults to generating a document style interface whereas JDeveloper defaults to generating an RPC style interface. The end result is that JDeveloper wraps the document interface in something that looks document like - thus your client. To see how to handle this right now, check out this sample - you have to parse the XML:
http://otn.oracle.com/tech/webservices/htdocs/series/net/content.html
In the preview of JDeveloper 9.0.3 which is due quite soon - next few weeks roughly (crossing my fingers) - JDeveloper will wrap .NET document based Web services in a much more elegant wrapper - giving you exactly what you are looking for - a method called Validate rather than a vector of Elements.
What I don't understand in your sample, however, is that you have WSDL generated from JDeveloper versus WSDL generated from .NET. Did you also do an implementation of the validate method in Java too?

Writing a web service that returns a table

Hello Experts,
I'm a bit new to J2EE programing and will appreciate your help.
The main question is:
What is the best way to return a table from a web service?
In details:
I wrote an EJB calling an RFC.
The RFC returns a table.
I've created a web service from this EJB and need to return the above table as an output parameter.
What is the best way of passing the JCO.Table as an output parameter?
Should I pass it as an Object (and the client will take care of the casting)
or - is there a simple type I should convert the table to before passing it?
Thanks for your help, Adi.

Hi Adi,
The way I always return a JCO table in my Webservice Interface is returning an Interface.
Say you JCO table is a Person with different attributes in it.
Then I create an Interface IPerson with methods like
public abstract String getName(); etc.
I also create an object Person with methods:
public String getName() {
return name;
In my bean the I have a method:
public IPerson getJCOPerson() {
//retrieve the JCO table person
IPerson pers = new Person();
pers.setName(//name from JCO table);
etc.
return pers;
I hope this helps you further.

Web Service in Workflow not writing back

Hi,
Ive created a simple Web service that gets the supervisor Id from the form creator Id.
Ive tested the service on the SOAP services page and it works as expected.
But when I try to use this webservice in a workflow it doesnt write the values back into the from-variables.
Also, when you assign the formvariables to the WS-variables in the QPAC properties, the xpath boxes are not really always at the same place, ie. not filled with data or the like.
Is there a serious bug in the webservices QPAC?
Im using LC WF designer 7.0.
Id be thankful for any kind of advice how I can get webservices to run correctly in the designer.
Cheers
Gunther

Hi Gunther
I'm not sure why you're not getting return values.
I suggest you actually try using the external web services, and see whether they work.
One of the issues may be that the wsdl of the web service you're invoking is very complex, more complex than the parser that is built into the Adobe Web Service QPAC is capable of handling. So the web service may be executing correctly, but the data is not being extracted correctly. Perhaps! If this is the case, we do have another web service QPAC you may want to try. It's takes a simpler approach than the Adobe one - rather than trying to parse the schema and present variables to you, it simply allows you to provide a xml input document, and returns a xml output document. You can embed process variables into the input doc, and can assign the output do to an XML variable, where you can use XPath expressions to extract the data. This is currently in beta, if you'd like an early copy, please let me know.

Writing RESTful Web Services

I sure hope I'm in the right spot for this, as I have run out of places to look for answers.
I need to write a web service. I can find all the information in the world on consuming RESTful webservices, but I need to write one in Coldfusion. I have a service that will return JSON, but I don't know how to make them RESTful.
We are using these services to communicate with a Rhosync Server, and that portion has already been written. All I have to go on is how to test the call, and what data will be returned. The test call I was given is:
$ curl -i -H 'Accept: application/json' --user username:password 'http://coldfusionServer.domain.ca/appname/users/'
Is there a specific location that the CFCs should be, or a setting I need to have in the CFAdministrator?
Right now, I have gotten to the point that if I go to
http://coldfusionServer.domain.ca/appname/services/user.cfc?method=remoteGetUser&uName=Jen n&pass=jenn
I can get back the data I want.
The CFC I have are simple queries, which return JSON data (I am getting the correct format back) - it's an array of structs.
Any help - links, code examples, explanations of how simple (I Hope) it is to read in a RESTful call, and return JSON back, would be most appreciated.
Thanks!
Jenn

The easiest way to get this working is to use some form of URL rewriting in the webserver. Such a rewrite could bes set up to translate http://coldfusionServer.domain.ca/appname/users/ to something like http://coldfusionServer.domain.ca/appname.cfc?method=users. The the username and password that are being sent are available to your application in the CGI scope just as the Accept header is.

QName error while calling a web service from Sourcing

I need to call a web service from Sourcing script. The web service team has provided us the WSDL and I have generated the required stubs using wsimport and packaged the required java classes in a custom JAR. Now while calling a web method using this jar from my script, I am getting and exception. The exception message that I printed out was this:
Caught exception e with msg Connection IO Exception. Check nested exception for details. (Connection
IO Exception. Check nested exception for details. (Connection Exception; nested exception is:
java.lang.IllegalArgumentException: cannot create QName from "null" or "" String).)
The same jar and same code works fine when called from a standalone java program.
I am not using or creating QName anywhere in my script. The only place where QName is used is in the generated java class and there it is created from the correct namespace URL
Can anyone please help me out in figuring out what is the issue?

How to Send and Receive Large Amounts of Data to and from a Web Service

Hi All,
My requirement is: .Net Web service should receive a file and services do some modification in that file and return the file. I need to write client (using Java) to invoke that web service. Please help in writing java client code for accessing that service. Suggest if any changes required in Web service code also.
My .Net web Service web method code:
[WebMethod]
public byte [] ByteEcho(byte[] data) {
- Some modification code -
return data;
}

that will work fine for small files. it will potentially cause OutOfMemoryErrors on client and/or server for large files. if you want to send/recieve large files, you need to stream them.
also, be aware that you cannot send raw byte[] via xml, you will need to encode the data using some sort of binary -> text encoding like Base64 encoding.
