Hi I'm using axis1.4 and wss4j. When I define in client-config.wsdd for WSDoAllSender and WSDoAllReceiver different signaturePropFiles where I have different key stores defined with different certificates, I'm able to have different certificates for sending and receiving. But when I use the same signaturePropFiles' with the same keystore. I get this message when I try to send a message:

  org.apache.ws.security.components.crypto.CryptoBase -- Cannot find key for alias: [monit] in keystore of type [jks] from provider [SUN version 1.5] with size [2] and aliases: {other, monit}

How to have two certificates for wss4j in the same keystore? why it cannot find my certificate there when i have two certificates in one keystore.

I have the same password for both certificates regarding PWCallback (CallbackHandler)

My properties file:

org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin 
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=keystore
org.apache.ws.security.crypto.merlin.keystore.alias=monit
org.apache.ws.security.crypto.merlin.alias.password=***
org.apache.ws.security.crypto.merlin.file=key.jks

My client-config.wsdd:

  <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
