WebService Client Generation Error with JDK8

Question

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

The following works for wsimport 2.2.9 included in jdk 1.8.0_66:

wsimport -J-Djavax.xml.accessExternalSchema=all ....

In my case adding:

javax.xml.accessExternalSchema = all

to jaxp.properties didn't work, I've to add:

javax.xml.accessExternalDTD = all

My environment is linux mint 17 and java 8 oracle. I'll put it there as an answer for people with the same problem.

I tested this for version 2.4 of artifact org.codehaus.mojo and that worked ~

<plugins>
    <plugin>
