How to set a default trust store just for DirContext not the whole JVM

Question

I need to connect to a secure LDAP server ( URL is ldaps://..../). The Server certificate in this LDAP server is a self signed cert so I need to put this certificate in my Keystore as well for me to connect to it.
My code is something like :
  DirContext ctx=null;
    Properties prop = .... ;
    // I set URL etc. in this.
    KeyStore ks = some_function_call();
    // save this keystore to file
    java.io.FileOutputStream fos =  new java.io.FileOutputStream("/tmp/newKeyStoreName.jks");
    char[] password = .....
    ks.store(fos, password);
    fos.close();
    // set this keystore as the default Keystore.
    System.setProperty("javax.net.ssl.trustStore", "/tmp/newKeyStoreName.jks");
    System.setProperty("javax.net.ssl.trustStorePassword", ...);
    System.setProperty("javax.net.ssl.trustStoreType", "jks");
    ctx = new InitialDirContext(prop);My problem is when I do a System.setProperty it makes it the default trust store for the whole JVM. I want a solution that would use this trust store only for the DirContext as I do not want this keystore to be used for other parts of my code. And its an MT application so setting keystore back to default one after this LDAP query gets over won't work.
I tried changing System.setProperty to props.put() it doesn't work.
Any ideas?

I have the same problem. I have to make 2 different SSL calls to 2 different 2 servers and if I set to System truststore and keystore properties I have a problem, 'cause those are different for each server.
I you have found the solution in the meanwhile, maybe you can write it here.
thanks,
