• How to enable Jetty to support cometd/reverse ajax while let it listen to port 80?

  - by janetsmith

  Hi, I would like to use cometd / reverse ajax capability of Jetty 7. I tried to configure it so it listen to port 80, instead of 8080. However, according to http://jetty.mortbay.org/jetty5/faq/faq%5Fs%5F200-General%5Ft%5Fapache.html , Apache can be configured as a HTTP/1.1 proxy to pass selected request to the Jetty using the HTTP/1.1 protocol. This is simple to configure and use, but current versions of the apache mod_proxy do not support persistent connections. As far as I know, the reverse ajax in jetty is depending on continuation (I guess it is persistent connection). So how to let jetty support reverse ajax, while coexist with apache server? Thanks.

  Let's say I have a table containing following data: | id | t0 | t1 | t2 | | 1 | 4 | 5 | 6 | | 2 | 3 | 3 | 2 | | 3 | 6 | 4 | 5 | | 4 | 4 | 5 | 5 | I want to retrieve all the rows containing 4, 5, 6 (regardless the position of numbers in the tables), so row 1 & row 3 will be selected. How to do that with SQL query?

• cryptic error message: Length of Bind host variable exceeds MaxLength

  - by janetsmith

  Hi, I've encountered a cryptic error message thrown by Sybase IQ server. com.sybase.jdbc2.jdbc.SybSQLException: ASA Error -1001019: Function not supported on varchars longer than 255 Length of Bind host variable exceeds MaxLength , -- (df_Heap.cxx 2145) at com.sybase.jdbc2.tds.Tds.processEed(Tds.java:2636) at com.sybase.jdbc2.tds.Tds.nextResult(Tds.java:1996) at com.sybase.jdbc2.jdbc.ResultGetter.nextResult(ResultGetter.java:69) at com.sybase.jdbc2.jdbc.SybStatement.nextResult(SybStatement.java:204) at com.sybase.jdbc2.jdbc.SybStatement.nextResult(SybStatement.java:187) at com.sybase.jdbc2.jdbc.SybStatement.updateLoop(SybStatement.java:1642) at com.sybase.jdbc2.jdbc.SybStatement.executeUpdate(SybStatement.java:1625) at com.sybase.jdbc2.jdbc.SybPreparedStatement.executeUpdate(SybPreparedStatement.java:91) at ibs.dao.CM3RM1DAO.updateToTable(CM3RM1DAO.java:197) at ibs.dao.CM3RM1DAO.isXMLProcessed(CM3RM1DAO.java:88) at ibs.xml.parser.XMLParser.parsingXMLIntoBO(XMLParser.java:2125) at ibs.common.util.MainClass.main(MainClass.java:74) We have several columns (DESCRIPTION etc.) which are of type varchar(4000). However I can update them directly without having any error. And, I don't see any code specifying any bind variables, so I have no idea where the message comes from. This is the code (I've modified it a bit): String sql = "UPDATE TABLEX SET " + "COMPANY = ?, CUSTOMER_REFERENCE= ?, " + "STATUS = ?, CONTACT_FIRST_NAME = ?, CONTACT_LAST_NAME = ?, " + "SEVERITY = ?, PRIORITY_CODE = ?, REQUESTEDDATE = ?, " + "CLOSE_TIME = ?, LEAD_TIME = ?, CHANGE_REASON = ?, MODTIME = ? WHERE NUMBER = ?"; stmt = conn.prepareStatement(sql); for loop here { stmt.setString(...); . . stmt.executeUpdate(); } Any help is appreciated

• How to code for Alternate Course AKA Rainy Day Scenary?

  - by janetsmith

  Alternate course is something when user doesn't do what you expected, e.g. key in wrong password, pressing back button, or database error. For any programming project, alternate course accounts for more than 50% of a project timeline. It is important. However, most computer books only focus on Basic Course (when everything goes fine). Basic course is rather simple, compared to Alternate course, because this is normally given by client. Alternate course is what we, as a programmer or Business Analyst needs to take care of. Java has some built-in mechanism (try-catch) to force us to handle those unexpected behavior. The question is, how to handle them? Any pattern to follow? Any guideline or industry practice for handling alternate course?

• How to figure out which record has been deleted in an effiecient way?

  - by janetsmith

  Hi, I am working on an in-house ETL solution, from db1 (Oracle) to db2 (Sybase). We needs to transfer data incrementally (Change Data Capture?) into db2. I have only read access to tables, so I can't create any table or trigger in Oracle db1. The challenge I am facing is, how to detect record deletion in Oracle? The solution which I can think of, is by using additional standalone/embedded db (e.g. derby, h2 etc). This db contains 2 tables, namely old_data, new_data. old_data contains primary key field from tahle of interest in Oracle. Every time ETL process runs, new_data table will be populated with primary key field from Oracle table. After that, I will run the following sql command to get the deleted rows: SELECT old_data.id FROM old_data WHERE old_data.id NOT IN (SELECT new_data.id FROM new_data) I think this will be a very expensive operation when the volume of data become very large. Do you have any better idea of doing this? Thanks.
