Error Parsing /index.xhtml: not supported setting property http://xml.org/sax/properties/lexical-handler

Question

I am trying to build a project using JSF, JPA, Spring, but I am not able to succeed. I am using JBoss as my server. It shows no error, but shows 404 error. Interesting thing is that when I use Tomcat, then the console is clear, but on loading page it shows,

Error Parsing /index.xhtml: not supported setting property http://xml.org/sax/properties/lexical-handler

Here's the complete stack trace

How is this caused and how can I solve it?

Answer 1

This error comes from pull-parser which is an optional dependency of dom4j. You might be inadvertently getting pull-parser on your classpath even though it's optional for dom4j. Try explicitly excluding it and using your JDK's built-in parser instead (e.g. com.sun.org.apache.xerces.internal.parsers.SAXParser) which it should do by default then.

This question is 6 years old, so the following cannot have been the problem, but: in my Gradle project upgrading from Gradle 5.4 to Gradle 6.5 suddenly resulted in pull-parser being on the classpath because of a dependency on dom4j even though, as mentioned, the dependency of dom4j on pull-parser is optional and previously that wasn't happening. I've reported this to the Gradle project: https://github.com/gradle/gradle/issues/13656.

Answer 2

I get rid of the error by adding following dependency (in Gradle syntax):

implementation 'pull-parser:pull-parser:2.1.10'
