The Web Services-Interoperability Organization (WS-I) was formed by Oracle and other industry leaders to promote the interoperability of web services technologies across a variety of platforms, operating systems, and programming languages. JDeveloper provides tools that allow you to test the interoperability of web services by checking that the services conform to the WS-I Basic Profile (currently Version1.1).

WS-I analyzes web services for interoperability across four areas:

A set of test assertions is used to test a web service for conformity across these areas.

This How To document describes the steps to analyze a service for conformance to the Basic Profile using JDeveloper's integrated WS-I testing environment. The HTTP Analyzer is used to monitor and log running web services and you can use any WS-I conformant analyzer and test assertions (called the testing tools) to check conformance with the Basic Profile. In this document, you use the tools provided by WS-I.

Using JDeveloper a tested web service can be:

This How To shows you how to analyze each of these types of service.

Install Test Tools

  1. Download and extract the Java version of the testing tools from This updated version is designed to test the Basic Profile1.1.
  2. In JDeveloper, open the Preferences dialog (Tools-->Preferences) and navigate to the WS-I Testing Tools preferences.
    1. Set the Home Location to your stored testing tools location
    2. You need to specify the Test Assertions document that you plan to use. A Test Assertions document is included as part of the testing tools that you downloaded in the step above so if you intend to use this one, check the Specify Test Assertions Document check box and navigate to the \common\profiles subdirectory of the location where you unzipped the downloaded file. Select the BasicProfile_1.1_TAD.xml file and click Open. However, if you wish to use your own set of assertions, specify its location here.

Test the WSDL description of a service

This How To uses an Oracle J2EE web service as an example. You can also generate an Apache SOAP web service and a JAX-RPC web service using the JAX-RPC extension available from OTN. It is outside the scope of this How To to provide a detailed description of publishing and running a web service.

Running the Analyzer against the WSDL file

  1. Create HelloWorld Java class

    public class HelloWorld
    public HelloWorld()
    public String sayHello(String name)
    return "Hello " + name;

  2. Publish as Oracle J2EE web service named HelloWorldService
  3. If the Log window is not open, use the menu View -> Log Window to display it
  4. Use context menu of generated HelloWorldService to analyze the WSDL file

  5. Note that the log window returns the messages from the WS-I testing tool. The WS-I tools and output are fully integrated into the JDeveloper IDE

  6. Note that the WS-I Profile Conformance Report (wsi-report.html) is generated and opened for viewing

Reading the Conformance Report

  1. Scroll down to the Summary section. Note that this WSDL file has passed the interoperability checks. Also note that the report is broken into four areas (discovery, description, message, envelope)

  2. Scroll down to the Artifact: discovery section. The discovery section covers the conformance of a web service's entry in a UDDI registry. In this example a UDDI registry was not used - so all the assertions are flagged as Missing Input. Note: Missing inputs do not constitute failure, however you should check that you are expecting missing inputs (as in this case).

  3. Scroll down to the Artifact: description section.
  4. Scroll down through the Summary Table and note the color scheme used for Assertion IDs. Those that have passed the conformancy checks are listed in green; those to which the checks are not applicable are listed in blue, and those that have some input missing are listed in red.

  5. You can click on any Assertion ID to see details about the selected assertion. Click BP2098 to see the details of its Test Assertion to understand why it has been flagged as having input missing. As you see from the screenshot below, it highlights the fact that the import element in the WSDL has an empty value for the location attribute.

  6. Scroll down to the Entry list table. This table allows you to see the test results for the various component types in the web service. Click the Reference Id for the sayHello message type.
  7. Note that the two assertions in this message have passed the conformancy test.

  8. Scroll to the Artifact: message section of the report. This section of the report tests the conformancy of the messages being passed between a client and a web service. In this example we are testing a WSDL file only, so all the inputs to this section are flagged as missing

Test the messages of a running service

To test the HelloWorldService you run it using the embedded OC4J in JDeveloper and generate a Java proxy client to call it. It is outside the scope of this How To to provide detailed steps on achieving this, but if you need guidance on how to do these steps, refer to the OBE tutorials, Developing Contract-Driven Web Services Using JDeveloper and Developing, Deploying and Managing Web Services Using JDeveloper and Oracle Application Server on OTN.

Running the HTTP Analyzer against the WSDL file

  1. Run the HelloWorldService you created earlier using the embedded OC4J.
  2. Generate a Web Service proxy and add the following line to the Main method

    System.out.println(myPort.sayHello(" to you "));

  3. Run the proxy and view the output in the Log window

    hello to you
    Process exited with exit code 0.

  4. Open the HTTP Analyzer from the View menu and click the green Start button

  5. Run the client again. Note the request/response packets are listed in the HTTP Analyzer.

  6. To see the contents of a packet pair, select it in the History page, then click the Data tab. The data page shows the value that was sent to the web service in the request information (left panels), and the value returned by the web service in the response information (right panels).

    If you have run other things with the HTTP Analyzer started, you can use the Previous Request/Response Pair and Next Request/Response Pair buttons to examine other packet pairs.
  7. Stop the HTTP Analyzer by clicking the red Stop button. Then click the WS-I Analyze button (last icon on the right) to launch the WS-I Analyze wizard. The WS-I Profile Conformance Report is produced.

  8. To close the HTTP Analyzer window, click the x on the HTTP Analyzer tab.

Reading the Conformance Report

  1. Scroll down to the Summary section. Note that, again, this service has passed the conformancy checks. Again, the report is broken into the four areas (discovery, description, message and envelope)
    The Description and Discovery sections should be the same as in the WSDL report created earlier in this example
  2. Under the Summary section, click on the message link to navigate to the Artifact: message section. Notice that this time most of the assertions have passed the checks, with a few reported as Not Applicable. However there are no failures.

    ( If the table shows all the assertions as Missing Input, then there is a mismatch between the endpoint that is named in the conformance report and the endpoint that is being returned over the wire. See

Test the discovery of a service via a UDDI registry

In this release of JDeveloper you can test the WSDL file of a web service from a UDDI registry entry. You cannot use JDeveloper to analyze the Discovery portion of the Basic Profile that checks conformance of the UDDI Registry entry itself.

Locating a web service in the UDDI registry

  1. In the JDeveloper Connections Manager, expand the UDDI Registry node. Note that it contains a default connection to the XMethods Public UDDI Registry. Right-click this connection and choose Find Web Services from the context menu. The Find Web Services wizard is invoked
  2. In the wizard choose to search by category, then select the UDDI Types taxonomy and expand the Web Service Specification and XML Based Web Service Specification nodes. Choose Web Service Described via WSDL and shuttle it into the Selected pane and then click Next.

  3. A list of tModels is displayed. You scroll through the list to select a tModel. In reality this would be the tModel for a web service you plan to use in your application, and which you first want to check for WS-I Basic Profile conformance. For this How To select Address Finder(Netherlands) and click Next.

  4. Step 5 of the wizard displays details of the tModel you have selected. When you click Finish JDeveloper offers you a number of choices for what to do with the web service. Specify that you want to generate a proxy for the service into your project.

  5. The Create Web Service Proxy wizard is invoked. Once the proxy has been created you see the service in the UDDI Registry node in the Connections Navigator

Analyzing the WSDL

  1. In the UDDI Registry expand the new node to identify the WSDL. Right-click the WSDL and from the context menu, choose WS-I Analyze WSDL

  2. Browse the generated wsi-report.html Description section for conformance failures and warnings


Problem Possible Solution
Message Assertions all have Missing Input You are running a WSDL analysis only so only the Description assertions are tested

The machine name and port no. captured in the wsi-report.html do not correspond to the name and port being returned 'over the wire'. This is most likely to occur when you are running the service in the embedded OC4J. Check that the port number is 8988 (in the WSDL file) before you start to run the TCP Packet Monitor. Also, try changing the machine name to the IP_address or the hostname (in lower case). See the JDeveloper online Help topic Analyzing Web Services Running in the Embedded Server for more details

Service Name and Port No. of WS-I Analyze Web Service Wizard are blank The web service is not running. Deploy and start the service or use the embedded OC4J
The machine name and port no. do not correspond (see above)
HTTP Analyzer does not capture request and response data Check your proxy settings. If you have problems making connections from JDeveloper you may need to change the proxy server settings you use. For example, if you are connecting to an IP address behind a proxy server, and your machine is also behind the same proxy server, then make sure that JDeveloper's web proxy preferences exclude the IP address you are trying to connect to. For more information see JDeveloper online Help topic Proxy Settings and the HTTP Analyzer
Expanding UDDI Registry and XMethods node gives a 'Failed to Find Business Entites' message As above, you need to check your proxy settings. If you have problems making connections from JDeveloper you may need to change the proxy server settings you use. For example, if you are connecting to an IP address behind a proxy server, and your machine is also behind the same proxy server, then make sure that JDeveloper's web proxy preferences exclude the IP address you are trying to connect to.
Discovery section of wsi-report.html has missing inputs JDeveloper does not test the Discovery assertions of WS-I Basic Profile 1.0
Search by Category of IBM/Microsoft Public registry does not return enough rows Sometimes providers place restrictions on the number of rows that are returned by a Category search. There is now way to get round this. Category searching is most effective when used for private UDDI instances.


JDeveloper seamlessly integrates the testing of web services against WS-I Basic Profile 1.1. You can test both the description and messages of services. It is up to the user to decide whether failure to meet a specific Basic Profile assertion will impact the interoperability of a particular service in their environment.
