Errors/Warning compiling a WSDL file - but the generated Java sources are ok

[weberhofer]

First: Thanks for all the new contributions to the project!

I have tried to update a project which creates java sources from a WSDL. Unfortunately I see the following exception on invoking the compiler:

[INFO] Sources are not up-to-date, XJC will be executed.
[WARNING] Error while parsing schema(s).Location [].
org.xml.sax.SAXParseException; Versuchen Sie, WSDL zu kompilieren? Unterstützung für WSDL ist zu Testzwecken bestimmt. Eine Aktivierung ist mit der Option -wsdl möglich.

...

The exception asks something like "Do you try to compile WSDL? Support for WSDL is for test purposes. You can activate it with the option -wsdl.

With version 0.14.0 everything was working without that message. However, the tool creates the Java-Codes as expected!

The relevant section in my pom.xml is:

			<plugin>
				<groupId>org.jvnet.jaxb2.maven2</groupId>
				<artifactId>maven-jaxb2-plugin</artifactId>
				<version>0.15.1</version>

						</plugin>
					</plugins>
				</configuration>
			</plugin>

[mattrpav]

Please try to add the WSDL option as the error message indicates

see this example: https://github.com/highsource/maven-jaxb2-plugin/tree/master/tests/wsdl

<plugin>
				<groupId>org.jvnet.jaxb2.maven2</groupId>
				<artifactId>maven-jaxb2-plugin</artifactId>
				<configuration>
					<schemas>
						<schema>
							<url>http://www.webservicex.net/globalweather.asmx?wsdl</url>
						</schema>
					</schemas>
					<schemaLanguage>WSDL</schemaLanguage>
				</configuration>
			</plugin>

[weberhofer]

Thanks for your response. This has already been confgured in the first line of the section. Switching over to the way to configure does unfortunately not change anything. As in the other cases, the sources are correctly generated.

I have found older issue having the same warning noted: #96 (comment)

Maybe an additional parameter "-wsdl" must be set when invoking xjc for WSDL-files? As everything works, the issue is not that important but it is a little bit annoying.

[yanivnahoum]

I have the exact same issue, and my configuration is identical to that of @weberhofer.

I have a similar error after upgrading from 0.14.0 to 0.15.1

Error message:

I'll take a look at it this weekend. Seems odd since the root of the stack trace is the xjc layer.

Hi, any update here?

[DeepanshuRastogi1]

I'm facing the same issue when upgrading to version 0.15.1 with java 17 and spring boot 2.7.0

Any news with it? My configuration is similar to others on JDK 17

[gadton]

I've noticed the same exception but all the sources were generated on JDK 17.
I've noticed no change after adding

<args>
   <arg>-wsdl</arg>
</args>

[fabian-froehlich]

I am also experiencing this exception on JDK 17. But It looks like it has no effect.

[ielkhalloufi]

I am also experiencing this exception with JDK 17 and Spring boot 2.7:
