Problem with SAXParserFactoryImpl dependency

2020-06-06T15:06:26Z

Hi all,
I’m experiencing an error related to SAXParserFactoryImpl class due to transitive dependencies on net.sf.jasperreports library.
I’m developing a service module on Liferay CE 7.3 GA1, using Java 1.8 and maven.The error I get is the following:

Caused by: javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found

I checked the /liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/webapps/ROOT/WEB-INF/lib folder and the previous jar is included.
I guess the library is included as jar from tomcat classloader.
I tried to:
1. Include on Pom.xml the xercesImpl dependency with compiled scope. I got the same error
2. Include on pom.xml the xercesImpl dependency with provided scope. I got the same error
3. Remove the xercesImpl from Pom.xml. I got the same error.
I tried to search on google the error related to xercesImpl libraries, anyway I have not found the solution.
Have you ever experienced this problem? How did you solved it?
Thank you.
Best regards,
Alex
