Hi all. I develop the web-console for jbpm server and I tried to use IdentityManagement component for it. When I access IdenityLoginModule, and call a login() method, I get an IllegalArgumentException, which I cannot avoid in anyhow. Here is the listing of login method: public boolean login() throws LoginException { // get userName and password NameCallback nameCallback = new NameCallback(null); PasswordCallback passwordCallback = new PasswordCallback("pass",false); try { callbackHandler.handle(new Callback[]{nameCallback, passwordCallback}); } catch (Exception e) { e.printStackTrace(); throw new LoginException("callback failed"); } .... .... .... } In the first string there is a constructor of NameCallback, which is: public NameCallback(String prompt) { if (prompt == null || prompt.length() == 0) throw new IllegalArgumentException(); this.prompt = prompt; } As soon as NameCallback constructor is invoked with a null argument, the code throw IllegalArgumentException immediately, and I cannot do nothing.. Can you explain how is it possible, if this class was tested or if I do something wrong?.. I use JBPM 3.2.2, jbpm-identity.jar-3.2.2 e JDK 1.6.0. Thanks a lot!
