Dear Gurus,
I really need your help. I've ben struggling my brain in order to develop a webservice which can show the content of one or several roles. Till now I could get a role list, but when trying to get attributes of role's content I'm geting class cast exception
I've tried many options, but always ended with a class cast exception
All your suggestions will be very appreciatted. Thanks in advance
My base are this posts:
Query pcd roles through api
Exposing the Enterprise Java Bean as a Web Service - Developing Java EE 5 Applications - SAP Library
Browse portal content and object properties - Code Gallery - SCN Wiki
This is my code:
public List<PortalObject> getContentsFromRole(String roleName)
{
this.portalObjArray = new ArrayList<PortalObject>();
Hashtable roleList = getRoleListByName(roleName);
Enumeration keyEnum = roleList.keys();
try
{
InitialContext ctx = null;
try
{
IUser principalObj = null;
try
{
// getting the SAP user.
IUserFactory userfact = UMFactory.getUserFactory();
principalObj = userfact.getUserByLogonID("e_aaceval");
}
catch (UMException umex)
{
portalObjArray.add(new PortalObject("getContentsFromRole() UMException:" + umex.getMessage()));
}
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
if (principalObj != null)
{
env.put(Context.SECURITY_PRINCIPAL, principalObj);
}
env.put(Constants.REQUESTED_ASPECT, IPcdAttribute.PERSISTENCY_ASPECT);
ctx = new InitialContext(env);
}
catch (NamingException nex)
{
//TODO
}
while (keyEnum.hasMoreElements())
{
String roleKey = (String) keyEnum.nextElement();
String val = (String) roleList.get(roleKey);
PortalObject po = new PortalObject();
po.setId(roleKey);
po.setName(val);
portalObjArray.add(po); // role data
IPcdContext rootRole = (IPcdContext) ctx.lookup(roleKey);
Object titleObj = rootRole.getAttributes("").get("com.sap.portal.pcm.Title");
portalObjArray.add(new PortalObject("getContentsFromRole() titleObj:" + titleObj.toString()));
if (titleObj instanceof IPcdAttribute)
{
IPcdAttribute titleAtt = (IPcdAttribute) titleObj;
String title = titleAtt.get().toString();
portalObjArray.add(new PortalObject("getContentsFromRole() title:" + title));
}
}
}
catch (Exception ex)
{
//TODO
}
return portalObjArray;
}
And this is the error:
Cannot cast class com.sapportals.portal.pcd.gl.PcdGlContext to interface com.sapportals.portal.pcd.gl.IPcdContext
