Camel - which pattern to use in order to complete xml with values from other services -

-

I have an XML, which is similar to the following, in which some elements have been created by the URL. That url is another webservice in which another XML is what I need to do, my XML is to complete with information from the webservice, and I want to achieve it with camel. Example goes here:

Initial xml 

  & lt; Root & gt; & Lt; Level11 & gt; Level1.txt & lt; / Level1 & gt; & Lt; Level12 & gt; & Lt; Level21 & gt; Http: // someservice / 11 & lt; / Level21 & gt; & Lt; Level21 & gt; Http: // someservice / 12 & lt; / Level21 & gt; & Lt; / Level12 & gt; & Lt; Level13 & gt; & Lt; Level22 & gt; Http: // someservice / 21 & lt; / Level22 & gt; & Lt; Level22 & gt; Http: // someservice / 22 & lt; / Level22 & gt; & Lt; / Level13> & Lt; / Root & gt;

http: // someservice is returning an XML that I need to convert to the original XML, for example

Http: // someservice / 11 return 

  & lt; Someservice & gt; & Lt; Test & gt; 11 & lt; / Test & gt; & Lt; / Someservice & gt;

http: // someservice / 12 returns 

  & lt; Someservice & gt; & Lt; Test & gt; 12 & lt; / Test & gt; & Lt; / Someservice & gt;

http: // someservice / 21 returns 

  & lt; Someservice & gt; & Lt; Test & gt; 21 & lt; / Test & gt; & Lt; / Someservice & gt;

http: // someservice / 22 returns 

  & lt; Someservice & gt; & Lt; Test & gt; 22 & lt; / Test & gt; & Lt; / Someservice & gt;

My final XML would be: 

  & lt; Root & gt; & Lt; Level11 & gt; Level1.txt & lt; / Level1 & gt; & Lt; Level12 & gt; & Lt; Level21 & gt; & Lt; Someservice & gt; & Lt; Test & gt; 11 & lt; / Test & gt; & Lt; / Someservice & gt; & Lt; / Level21 & gt; & Lt; Level21 & gt; & Lt; Someservice & gt; & Lt; Test & gt; 12 & lt; / Test & gt; & Lt; / Someservice & gt; & Lt; / Level21 & gt; & Lt; / Level12 & gt; & Lt; Level13 & gt; & Lt; Level22 & gt; & Lt; Someservice & gt; & Lt; Test & gt; 21 & lt; / Test & gt; & Lt; / Someservice & gt; & Lt; / Level22 & gt; & Lt; Level22 & gt; & Lt; Someservice & gt; & Lt; Test & gt; 22 & lt; / Test & gt; & Lt; / Someservice & gt; & Lt; / Level22 & gt; & Lt; / Level13> & Lt; / Root & gt;

So my question is, should I use the best pattern to achieve this result?

There are two panels in my JInternalframe. I want to add TopPanel to Jtree to nominate another. But I can not add Jaitari to the top of the panel.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
