java - NetBeans compiling error for JWS app -

i created app various .jar files; wanted execute program using jws netbeans launches building error, , gives me 2 errors:

c:\proyecto ouma\ouma.administracfdi.reader\nbproject\jnlp-impl.xml:253: following error occurred while executing line: c:\proyecto ouma\ouma.administracfdi.reader\nbproject\jnlp-impl.xml:845: jarsigner returned: 1 

then refer lines errors gave me:

<antcall target="generate-jnlp"/>  <sign-jars keystore="${jnlp.signjar.keystore}"            storepass="${jnlp.signjar.storepass}"                  keypass="${jnlp.signjar.keypass}" alias="${jnlp.signjar.alias}" mainjar="${dist.jar}" destdir="dist"                 codebase="${jnlp.codebase.value}" signedjarsprop="jnlp.signed.jars"                 **componentsprop="jnlp.components"> 

i'm signing app using self-sign option in netbeans.

another rare thing happens: when don't use signing option, app doesn't give building error.

thanks responses!
