in my project I'm using Apache MyFaces 1.1 lib, Spring 3.2.9, Java 8 and tomcat 8.

I'm getting following error while deploying in tomcat 

SEVERE: Servlet.service() for servlet [Persistent Faces Servlet] in context with path [/app_Palisades] threw exception [java.lang.Exception: javax.faces.FacesException: Problem in renderResponse: /YardSnap.xhtml @183,89 timeZone="#{yardSnapBean.timeZone}" null] with root cause

Jun 02, 2016 5:17:38 AM org.apache.catalina.loader.WebappClassLoaderBase modified
INFO: One or more JARs have been modified in the web application [/app_MyApplication
Jun 02, 2016 5:17:38 AM org.apache.catalina.core.StandardContext reload

Please help me, I'm facing this issue from 2 days.

Thanks in advance

  • How and why exactly did you override Apache EL with Oracle EL? If you already have no clue what I'm asking, then start with listing all JARs you have in `/WEB-INF/lib`. The stack trace at least tells that the webapp is using Oracle EL, which is strange as Tomcat itself already ships with Apache EL out the box. This very much suggests classpath pollution with wrong/duplicate/competing libraries supplied via webapp which only conflict server's own libraries, resulting in "weird" exceptions coming from internal classes like this. – BalusC Jun 02 '16 at 10:47
  • actually this project is a migration from weblogic to tomcat . that why , I've dependency in POM.XMl com.sun.el el-ri 1.0 – Shital Bisen Jun 02 '16 at 11:02
  • That's a server-provided dependency which you're supposed to mark as `provided`. This applies to all server-provided dependencies. This is most likely the answer you're looking for: http://stackoverflow.com/questions/8081234/how-to-properly-install-and-configure-jsf-libraries-via-maven/8081384#8081384 – BalusC Jun 02 '16 at 11:06
  • so what should I do, remove that dependency or to give provided or use some other library . I'm fully confused right now. – Shital Bisen Jun 02 '16 at 11:13
  • Take a pause and then read the given link once again with a fresh mind and logical thinking capabilities. – BalusC Jun 02 '16 at 11:14
  • OK . Thanks for replying.. :) – Shital Bisen Jun 02 '16 at 11:19
  • the above error is gone but some other issue I'm facing seems like database information is not right but it's proper . I'm using Spring-jdbc instead of commons-dbcp . error I'm getting is java.lang.UnsupportedOperationException: Not supported by BasicDataSource at org.apache.tomcat.dbcp.dbcp2.BasicDataSource.getConnection(BasicDataSource.java:1551) – Shital Bisen Jun 03 '16 at 13:30
  • That problem has a different cause. Just copypaste error message into [a search engine](https://google.com/search?q=java.lang.UnsupportedOperationException%3A+Not+supported+by+BasicDataSource+at+org.apache.tomcat.dbcp.dbcp2.BasicDataSource.getConnection) to find clues. – BalusC Jun 03 '16 at 13:37
