Tem como postar o conteudo do jnlp ?

segue…

<?xml version="1.0" encoding="utf-8"?>
<jnlp
spec="1.0+"
codebase="http://localhost:8080/Gerador"
href="Gerador.jnlp">
<information>
<title>gerador de Relatorios</title>
<vendor>Jesse</vendor>
<homepage href="http://localhost:8080/Gerador/index.html"/>
<description>Gerador</description>
<description kind="short">Gerador</description>
<icon href="logo.png"/>
<offline-allowed/>
</information>
<resources>
<j2se version="1.3+" href="http://java.sun.com/products/autodl/j2se"/>
<jar href="Executar.jar"/>
<property name="myProperty" value="Gerador de Relatórios"/>
</resources>
<application-desc main-class="relatorios.Main"/>
</jnlp>

Se estiver usando tomcat dentro da pasta webapp vc deve ter uma pasta chamada Gerador e dentro desta pasta deve estar o arquivo Executar.jar e Gerador.jnlp

No arquivo server.xml

&lt;/Host&gt;

&lt;jar href="Executar.jar" main="true" /&gt;

substitua seu jnlp por este

&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;!DOCTYPE jnlp PUBLIC "-//Sun Microsystems, Inc.//DTD JNLP 1.5//EN" "http://www.netbeans.org/jnlp/DTD/jnlp.dtd"&gt;
&lt;jnlp codebase="http://localhost:8080/Gerador" href="Gerador.jnlp"&gt;
  &lt;information&gt;
    &lt;title&gt;Gerador&lt;/title&gt;
    &lt;vendor&gt;Gerador&lt;/vendor&gt;
    &lt;homepage href="http://localhost:8080/Gerador"/&gt;
    &lt;description&gt;Gerador&lt;/description&gt;
    &lt;description kind="short"&gt;Gerador&lt;/description&gt;
    &lt;!-- icon href="seuIconeSeTiver.jpg"/ --&gt;
    &lt;!-- icon kind="splash" href="LogoSmall.jpg"/ --&gt;
    &lt;shortcut online="true"&gt;
      &lt;desktop/&gt;
    &lt;/shortcut&gt;
  &lt;/information&gt;

  &lt;security&gt;
    &lt;all-permissions/&gt;
    &lt;!--&lt;j2ee-application-client-permissions/&gt;--&gt;
  &lt;/security&gt;

  &lt;resources&gt;
	&lt;j2se href="http://java.sun.com/products/autodl/j2se" version="1.5+"/&gt;
	&lt;jar download="eager" href="Executar.jar" main="true"/&gt;

	&lt;!-- se tiver libs coloque todos aqui --&gt;

	&lt;!-- jar href="lib/antlr-2.7.6.jar"/ --&gt;
	&lt;!-- jar href="lib/asm.jar"/ --&gt;
	&lt;!-- jar href="lib/c3p0-0.9.1.jar"/ --&gt;

  &lt;/resources&gt;
  &lt;application-desc main-class="relatorios.Main"/&gt;
&lt;/jnlp&gt;
