Can we avoid specifying User ID & password for connecting to LiveCycle server through code?

Hi,

I am developing a JAVA program that connects to the LiveCycle ES server to assemble two PDF files. Here is some part of the code I am using. The code works fine.

Properties connectionProps = new Properties();
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_DEFAUL T_EJB_ENDPOINT, "jnp://localhost:1099");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_TRANSP ORT_PROTOCOL,ServiceClientFactoryProperties.DSC_EJB_PROTOCOL);
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_SERVER _TYPE, "JBoss");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDEN TIAL_USERNAME, "administrator");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDEN TIAL_PASSWORD, "password");

ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);

AssemblerServiceClient assemblerClient = new AssemblerServiceClient(myFactory);

If I do not use the credential info (user ID and password) I get some credential exceptions. Is there a way that I can avoid providing the credential information? The reason for this is I do not want to hardcode the user ID and password information as the password can change. Is there any other way to solve this issue?
