WSDL: (/YourProject/YourService?wsdl) is working fine but
Tester (/YourProject/YourService?Tester) is not working
Then, this can be solved using:
Create a new text file and rename it 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
Then, restart the glassfish server and you are good to go! Good Luck.
There is another way to fix this if you are facing this problem when working on a Maven Web Project:
(Since the above solution perfectly worked for me, I didn't test this solution:)
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 found the above plugin configuration on StackOverflow.
