axis2 - why pwcb.getPassword is null in this code -

-

i try add rampart security axis2 web service using rampart module.

so here have made:

  1. i have stored in database hashed value of "bobwww" password , salt

in pwcbhandler.java class

•i select stored in database password , hash

•i try hash same algorithm pwcb.getpassword() same stored salt

•check if new hashed password equal stored password

but receiving nullpointerexception decide check , wrote code

if(pwcb.getpassword()==null) {    try {         throw new exception ("passwordget pass null" +pwcb.getpassword());         }          catch (exception e)          {            // todo auto-generated catch block         e.printstacktrace();          } }

and see pwcb.getpassword() empty. here code of pwcbhandler.java

public void handle(callback[] callbacks)   throws ioexception,  unsupportedcallbackexception    {        (int = 0; < callbacks.length; i++)         {                       wspasswordcallback pwcb = (wspasswordcallback)callbacks[i];             try {               pasandsalt = getdataforchecking();                if(pwcb.getpassword()==null)             {                  try {                     throw new exception ("passwordget pass null" +pwcb.getpassword());                 } catch (exception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }             }                try {                 passwordforchecking = hash(pwcb.getpassword(),base64.decodebase64(pasandsalt[1]));               } catch (exception e) {                  // todo auto-generated catch block                 e.printstacktrace();             }                   if((pwcb.getidentifier().equals("bob")) && (passwordforchecking.equals(pasandsalt[0])) )               {                 return;               }           }

and here soaprequest sequeiry header

 var sr =                   "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +                 "<soapenv:envelope " +                    "xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" " +                  "xmlns:nilo=\"http://nilo\">"+                   "<soapenv:header>"+                   '<wsse:security xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\" soapenv:mustunderstand="1">'+                   '<wsse:usernametoken xmlns:wsu="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:id="123">'+                   '<wsse:username>bob</wsse:username>'+                   '<wsse:password type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#passwordtext">bobwww</wsse:password>'+                   '</wsse:usernametoken>'+                   '</wsse:security>'+                   "</soapenv:header>"+                   "<soapenv:body>" +                   "<nilo:getdataforchecking>" +                   '<nilo:data>'+tranxml+'</nilo:data>' +                     ' </nilo:getdataforchecking>'+                      '</soapenv:body>' +                      '</soapenv:envelope>';

according soap headers can see using plain text password instead of password digest. might need change rampart configuration 

<wsse:password type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#passwordtext">bobwww</wsse:password>

this might helpful you. http://wso2.com/library/240/

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
