Cannot instantiate iPortal Security Adapter:

work_ph

Hi everyone, 
 
I am trying to build a Security Adapter for my report in order to make the access on tomcat 5.5.23 secure. 
For this I followed the tutorials: 
<a class='bbc_url' href='http://www.birt-exchange.org/wiki/Security_Integration_with_the_Actuate_BIRT_Viewers/'>Security Integration with the Actuate BIRT Viewers - BIRT Wiki - BIRT Exchange</a> and <a class='bbc_url' href='http://www.birt-exchange.org/documentation/Manuals10/creating-custom-deployment-kit-apps.pdf'>http://www.birt-exchange.org/documentation/Manuals10/creating-custom-deployment-kit-apps.pdf</a> 
 
I write the custom class and copy it to the lib folder. I also adjust the web.xml 
 
Here my example: 
 
1st my Security Adapter class: 
 
 
 
 
SecurityMgrSession.java 
 
import javax.servlet.*; 
import javax.servlet.http.*; 
import com.actuate.iportal.security.iPortalSecurityAdapter; 
 
public class SecurityMgrSession extends 
com.actuate.iportal.security.iPortalSecurityAdapter { 
public SecurityMgrSession() { 
} 
 
/** 
* authenticate() to authenticate the user. 
*/ 
public boolean authenticate(HttpServletRequest request) { 
HttpServletRequest httpReq = (HttpServletRequest) request; 
boolean returnValue = false; 
String param = request.getParameter("uname"); 
return returnValue; 
} 
 
public String getPassword() { 
return null; 
} 
 
public String getUserHomeFolder() { 
return null; 
} 
 
public byte[] getExtendedCredentials() { 
return null; 
} 
 
public boolean isEnterprise() { 
return false; 
} 
} 
 
 
 
and my web.xml: 
 
 
<context-param> 
 
<param-name>SECURITY_ADAPTER_CLASS</param-name> 
<param-value>SecurityMgrSession</param-value> 
</context-param> 
 
 
the jar file SecurityMgrSession.jar lies in the folder WEB-INFlib and was created by the command jar cvf SecurityMgrSession.jar SecurityMgrSession.class 
 
Every time I try to open the URL for my report i get the following page in the browser: 
 
HTTP Status 500 - 
 
 
type Exception report 
 
message 
 
description The server encountered an internal error () that prevented it from fulfilling this request.

Hi,

which version of java are you using to compile your class? I've had this problem when I compiled with 1.5 and ran on a new installation of A10 iPortal. When compiled using 1.6 it worked fine.

Thank you very much for your help, SailRCG!
