No, our xquery can be simple or complex depend on customer requirement, it is not our control. xml document retrieval is part of xquery using doc('6301904f80000114/0601904f80007547.xml') .  

instead of 
for $article in doc('6301904f80000114/0601904f80007547.xml') return $article
are you suggesting to use below command. 
> XQUERY for $article in db:open('JunitDocbaseDB', '6301904f80000114/0601904f80007547.xml') return $article

but in case of db:open xquery, we need to know database name much before. where as in doc(...) xquery, no need to pass database name as part of xquery. we are getting xquery from client side and later on on server side, we are connecting to specific basex database and then run this doc(...) xquery. so db:open will not help us. 

connect to specific database:
=========================
    if(m_databaseName != null)
    xqs.setProperty("databaseName", m_databaseName);
    xqs.setProperty("user", m_administratorName);
 
    XQStaticContext xqsc;    
    m_conn = (XQConnection2) xqs.getConnection(m_administratorName, password);    

Run xquery :
==========
//got this query from client side
String xQuery = "for $article in doc('6301904f80000114/0601904f80007547.xml') return $article";

XQPreparedExpression xqPreparedExpr = null;
XQResultSequence resultSeq = null;
xqPreparedExpr = m_conn.prepareExpression(xQuery);
resultSeq = xqPreparedExpr.executeQuery();

running doc(...) xquery using above java program is working fine, if we open basexgui.bat and open database in GUI. otherwise throw error message. Is there any workaround to solve this doc(...) xquery.

Thanks,

Fine. If you want to access documents from the database, db:open is
always the better choice.
