Galera, estou começando a usar JWS. Porém quando tento rodar minha apliacação via JWS ele não está encontrando meu arquivo log4j.jar que está de do JAR principal da apliação. Está com a seguinte estrutura:

GUIVL.jar é o principal dentro de GUIVLjar tem a pasta lib/ que tem dentro dele o log4j.jar
Segue meu arquivo .jnlp

<?xml version="1.0" encoding="utf-8"?>

cara, não tenho bem certeza se é isto, mas edita o se jnlp
e dentro do resources voce deve referenciar as bibliotecas,
exemplo:

<resources>
        <j2se version="1.6+"/>
        <jar href="NOME_DO_MAIN.jar" main="true" />
        <jar href="BIBLIOTECA1.jar" />
        <jar href="BIBLIOTECA2.jar" />
    </resources>

Valeu!

Coloquei todas as bibliotecas declaradas no .jnlp. Até o log4j.properties eu declarei no .jnlp.
Ao fazer isto, ele da o seguinte erro:

com.sun.deploy.net.JARSigningException: Could not verify signing in resource: <a href="http://localhost:8080/tutorialjws/log4j.properties">http://localhost:8080/tutorialjws/log4j.properties</a>
