O jar do mysql ja está na minha pasta lib. Já procurei alguns tópicos, mas não consegui resolver.

Engraçado que junto do erro da lib você tem um NullPointer at com.agenda.model.AgendaDAO.salvar(AgendaDAO.java:21) . Não sei c é normal esse erro
Oq vc tem nessa linha?

Pq vc ñ remove a lib do driver da sua aplicação e ñ a coloca na pasta de biblotecas do tomcat?

Estranho mesmo. Mas talvez a aplicação dele execute normalmente até que seja chamado um método que use a conexão, dai da o nullpointer.

Ou ele ta sem o driver ou pode estar com o driver na lib do server e da aplicação.

williamdasflores 30 de abr. de 2012

Então nessa linha eu tinha um “rollback” dentro de um “catch”, comentei ele e o erro Nullpointer não aparece mais. Mas o outro erro ainda continua. Segue trace.

Hebert_Coelho 30 de abr. de 2012

E com relação aos jars?

williamdasflores 30 de abr. de 2012

Então…fiz o download do zip do hibernate e coloquei todos os da pasta “required”.
Vou listar aqui pra você quais estão na minha pasta lib

antlr-2.7.7.jar
dom4j-1.6.1.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.2.jar
hibernate-entitymanager-4.1.2.jar
hibernate-envers-4.1.2.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
javax.faces.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
jstl-api-1.2.jar
jstl-impl-1.2.jar
mysql-connector-java-5.1.19-bin.jar
slf4j-log4j12-1.6.4.jar
slf4j-log4j12-1.6.4-sources.jar

Hebert_Coelho 30 de abr. de 2012

Pq ou para q vc fez isso? O problema está com o jar do driver e não com hibernate.

williamdasflores 30 de abr. de 2012

Então listei todos pq fiquei com receio de estar faltando algum.
O jar do driver mysql eu até tinha trocado ele, pois eu estava usando 5.1.17 aí pensei que poderia ser isso…então coloquei esse que está listado o 5.1.19. Mas não surtiu efeito

romarcio 1 de mai. de 2012

Você está gerando um arquivo .war?
Se tiver, da uma olhada dentro dele e vê se a biblioteca do mysql está adicionada lá junto com as outras.

williamdasflores 1 de mai. de 2012

Não, não estou gerando .war. Estou rodando pelo eclipse mesmo.
Com relação as libs, estão corretas?

williamdasflores 6 de mai. de 2012

Consegui resolver. Coloquei o driver do mysql dentro da pasta “jre” que está dentro de “jdk”

JH-programador 14 de ago. de 2013

willians blz cara?
to com o msm problema que o seu so que uso o Jboss, mas o erro do trace e o msm.
nao entendi bem a sua soluçao sobre o erro… tipo vc jogou a lib dentro da pasta de instalaçao do jdk dentro do c:\programas?
