I have extracted rt.jar from SUSE Jre1.8 . I can see that rt.jar\sun\security\tools\keytool\CertAndKeyGen.class is existing in it . Then why i am getting java.lang.NoClassDefFoundError ?
Any help or suggestions ?

Trying to get JSON response with JavaEE JAX-B, Jasper and Glassfish 4.1.1, but I get error 500

I am learning WebServices with JAX-B and Jasper. I can easily generate XML response, but I want to get JSON response, but I get error 500.
Here is exception:
javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/xml/parsers/ParserConfigurationException
root cause
org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/xml/parsers/ParserConfigurationException
root cause
java.lang.NoClassDefFoundError: javax/xml/parsers/ParserConfigurationException
root cause
java.lang.ClassNotFoundException: javax.xml.parsers.ParserConfigurationException not found by org.eclipse.persistence.moxy [228]
Full server log: http://pastebin.com/Eq2KbyKJ
Okey, I tried with Tomcat, and it works, it seems that is Glassfish related problem, but I want to use Glassfish as server, since I use EJB in my projects.

It's a bug inside Eclipselink: https://bugs.eclipse.org/bugs/show_bug.cgi?id=463169 , try upgrading to the latest version?

SQLException stack trace

So I got sort of strange situation. I have Spring webapp and in it I have JNDI datasource that I have defined in tomcat's server.xml to connect to mysql database
I have mysql-connector-java 5.1.2 in my Maven pom.
Application works when I start it from localhost, but when I deploy it to remote tomcat it is not getting the call to the database.
This Exception occurs :
Couldnt execute sql CALL shareholders_company_list(?)
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Unable to create correct SQLException class instance, error class/codes may be incorrect. Reason:
** BEGIN NESTED EXCEPTION **
java.sql.SQLException
MESSAGE: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException
STACKTRACE:
java.sql.SQLException: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException
Is there away to avoid this ClassNotFoundException, so that I can get full stack trace, since it seems that explicit error why this happens is in MySQLNonTransientConnectionException, and I can't seem to reach it.

import required version(if you don't have any preference go for latest) of mysql-connector-java-latestVersion.jar under tomcat\lib

Tomcat Server Error

I am getting following error while starting my application:
SEVERE: Exception starting filter CSRF
java.lang.ClassNotFoundException: org.apache.catalina.filters.CsrfPreventionFilter
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
Tried to find jar for org.apache.catalina.filters.CsrfPreventionFilter on findjar.com but could not find anything.

You should check your tomcat installation, since this is a tomcat class.
