CROWD token and Jira / Confluence SOAP integration

I'm using CROWD and SSO for being able to log in in several applications such as Jira, Confluence and my own web application. My own web application provides a simplified user interface for searching Confluence pages and creating Jira issues. The connection web application in integrated into Jira and Confluence using their SOAP interfaces. SOAP integration is done with axis.

Now, I'm trying to get the whole set operated. I though that I could use the token received form CROWD (HttpAuthenticator.getToken()) and pass it as a parameter to the methods in the SOAP interfaces of Jira and Confluence. However, when I try to use that I get these kind of answers:

Jira:
org.springframework.remoting.RemoteAccessException: Cannot access remote service [

{http://spoink.solita.fi:8081/rpc/soap/jirasoapservice-v2}

jirasoapservice-v2]; nested exception is com.atlassian.jira.rpc.exception.RemoteAuthenticationException: User not authenticated yet, or session timed out.

Confluence:
org.springframework.remoting.RemoteAccessException: Cannot access remote service [

{http://spoink.solita.fi:8082/rpc/soap-axis/confluenceservice-v1}

confluenceservice-v1]; nested exception is com.atlassian.confluence.rpc.InvalidSessionException: User not authenticated or session expired. Call login() to open a new session

I tried to pass also a "foo" String as token. I got similar responses, meaning that I cannot be sure if this CROWD token is not meant for this kind of functionality at all.

My question is how could I utilize the SSO authentication in Jira /Confluence integration. I'm not willing to create an additional login page into my web application just for being able to get user's password. The password as a "real" text is needed for making login via in Jira / Confluence SOAP interface.
