Hello I have begun a migration from 5.5 to 6. Yes I know 6 is EOL but the migration from 5.5 to 6 has some more documentation compared to 5.5 to the latest version.
I followed the standard migration of libs and classes from /common /shared etc to the new /lin directory for 6.. The server engine runs and I can see the examples web pages come up. When I migrated my production webapps to the 6.0 instance however I get the following error. HTTP Status 500 - java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/index_jsp, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature Any insight on this is welcomed.. I notice in that my app has its own lib directory, does this means that there is a conflict with the lib files from the base directory ? ________________________________ Notice of Confidentiality: The information contained in this communication is intended solely for the use of the individual or entity to whom it is addressed and others authorized to receive it.
