WebService Client Generation Error with JDK8

I need to consume a web service in my project. I use NetBeans so I right-clicked on my project and tried to add a new "Web Service Client". Last time I checked, this was the way to create a web service client. But it resulted in an AssertionError, saying:

java.lang.AssertionError: org.xml.sax.SAXParseException; systemId: jar:file:/path/to/glassfish/modules/jaxb-osgi.jar!/com/sun/tools/xjc/reader/xmlschema/bindinfo/binding.xsd; lineNumber: 52; columnNumber: 88; schema_reference: Failed to read schema document ' xjc.xsd ', because 'file' access is not allowed due to restriction set by the accessExternalSchema property.

The default Java platform for NetBeans was JDK8 (Oracle's official version), so when I changed my netbeans.conf file and made JDK7 (from Oracle, as well) as my default, everything worked fine. So I think the problem is with JDK8. Here is my java -version output:

java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

For now, I'm keeping JDK7 as my default Java platform. If there is a way to make JDK8 work please share.


Well, I found the solution. (based on http://docs.oracle.com/javase/7/docs/api/javax/xml/XMLConstants.html#ACCESS_EXTERNAL_SCHEMA)

Create a file named jaxp.properties (if it doesn't exist) under /path/to/jdk1.8.0/jre/lib and then write this line in it:

javax.xml.accessExternalSchema = all

That's all. Enjoy JDK 8.


Not an actual answer but more as a reference.

If you are using the jaxws Maven plugin and you get the same error message, add the mentioned property to the plugin configuration:

...
<plugin>
  <groupId>org.jvnet.jax-ws-commons</groupId>
  <artifactId>jaxws-maven-plugin</artifactId>
  <version>2.3</version>
  <configuration>
    <!-- Needed with JAXP 1.5 -->
    <vmArgs>
        <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
    </vmArgs>
  </configuration>
</plugin>

I run ant builds within Eclipse IDE (4.4, Luna, on Windows 7 x64). Rather than modifying the installed JRE lib or any ant scripts (I have multiple projects that include XJC in their builds), I prefer to change Eclipse Settings "External Tools Configurations" and add the following to the VM arguments for the Ant build configuration:

-Djavax.xml.accessExternalSchema=all
