Migrating from ant to maven

I have migrated my project from ant to Maven using velocity frame work but I am getting following error:
SEVERE: Servlet /Labman threw load() exception

As the error message says :
java.lang.ClassNotFoundException:
org/apache/commons/lang/text/StrLookup
That means, that apache commons-lang is missing in your dependencies:
So you have to add the following to your pom:
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
In addition is to say, if you are using commons-lang3 but that has an other package name org/apache/commons/lang3.

You are probably missing this in your pom.xml:
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
Just add it under the tag <dependencies> and it should work.

ClassNotFoundException: javax.validation.ValidatorFactory

I am trying to run a Spring MVC application in my local machine through Tomcat, but I am seeing:
NoClassDefFoundError: javax/validation/ValidatorFactory
I have validation-api-1.0.0.GA.jar in webapp's lib folder. I am using Tomcat 7. Any guidance would be appreciated.

You have the necessary jar file you need in hibernate-validator. This jar includes the javax.validation.ValidatorFactoryvalidation-api. So if you are including validation-api explicitly, you might have dependency conflicts. If not, you might just be having class reloading issues. Try cleaning your tomcat and restarting your IDE.

add to pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>

😤 I encountered the problem when I launched my tests for the first time.
The problem comes from an incompatibility between the test dependency and the validation dependency.
📝 My pom.xml:
<dependency>
<groupId>jakarta.validation</groupId>
<artifactId>jakarta.validation-api</artifactId>
<version>3.0.2</version>
</dependency>
😀 I solved the problem, I replaced jakarta.validation-api for spring-boot-starter-validation.
📝 My pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>

I had the same problem.
For 2 months i was trying to find solution.
There was a error i made.
I copied hibernate validator jar and pasted it in java installation directory.
Now i was using maven which also downloaded the validator jar.
There where two jars present and so the error arise.
The problem was solved accidentally when i reinstalled java in my system.

For me it was a conflict with jakarta.validation version 3.0.1. Rolling it back to 2.0.2 fixed it.

Include jakarta.validation-api within your project jar file , and that will force Tomcat to use it. in pom.xml add scope provided as follows:
<dependency>
<groupId>jakarta.validation</groupId>
<artifactId>jakarta.validation-api</artifactId>
<version>3.0.2</version>
<scope>provided</scope>
</dependency>
good luck.

No idea whats going on and how its happening, cause when I do the same in my local box, I dont see any errors! My assumption is,using java 7 to build in local and using Java 8 in linux.
Is that whats happening or I am missing something else?

This issue occured to me because i didn't provide path in Deployement option in properties of project:
Right click on project ---> select "properties" --> Deployement assembly --> "ADD" option -->
select "java build path entries" --> select path

what is the Spring version? I think there is some issue with Spring 3 and Java 8.
If you are using Spring 3 change it to Spring 4 build and deploy using Java 8
or
Downgrade Java to 7 and use spring 3!

this is the prefect solution , i had been struggling since two days for the same.
Right click on project ---> select "properties" --> Deployement assembly --> "ADD" option --> select "java build path entries" --> select path(maven dependencies)-->Finish

http://papweb.wordpress.com/2011/07/29/spring-mvc-3-jsf-2-with-maven-2-and-tomcat/
and i am also getting the warning in faces-config like which shown in the below link :
Class org.springframework.web.jsf.el.SpringBeanFacesELResolver must extend the type javax.el.ELResolver

It would have been helpful to resolve if you had given your POM.xml because the exception clearly shows it cannot find necessary classes
java.lang.ClassNotFoundException: javax.servlet.jsp.el.ImplicitObjectELResolver
Check if you have dependencies for javax.servlet.jsp-api and javax.el-api in your pom.xml or add the below maven dependencies
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.2.1</version>

I tried to search for this error, but there seems to be very little information about it.
Does anyone have an idea?
Thanks.
EDIT: Here are the librairies I'm using
lib

Looking at the Spring 3.0 API reveals that the missing class is not part of version 3.x. I assume one of your Spring Jar files is still using the 2.5 version. Look at your pom.xml file to try to discover which Jar is still using this version.
Pay close attention to any of the jars in this list.
