Spring batch writer: add a terminator record after a group of records
You're right, footerCallback of FlatFileItemWriter will always be called even if there's an error in writing the records. You can pass the "group" variable to the footer callback (e.g., through ItemStream) and the callback can refer to the latest "group" and write if it's not null. So you don't have to care/define the last group before you start writing. Alternative: Following your current setup, I'm thinking if it's possible for you to get the number of records you are expecting to read. Using that count, inform your writer so it knows when to write the last termination record.

write method in spring batch not called
I tried your config with latest version of batch (2.2.1.RELEASE), spring (3.2.3.RELEASE) and quartz (2.2.0) and all works fine substituting file:input/report.csv with file:${user.dir}/src/main/java/input/report.csv. Are you sure file exists and doesn't throw a IllegalStateException: Input resource must exist (reader is in 'strict' mode): URL [file:input/report.csv] You can try use classpath:input/report.csv or build the real path of file (or check if your file is not empty...)

Using wait in your batch file to call the executable will wait for them to exit before. START /WAIT batch1.bat START /WAIT batch2.bat Hope this helps

How to write child record using itemWriter in spring batch
If reduce commit-interval to a small value in not an option because one B element can have up to 1mil C objects you can do that: Process class A to class B without creating the C objects in processed B object; in your BWriter attach a ItemWriteListener<B>.afterWrite() where you create/save C objects (related to List<B> received in listener) one-by-one so your memory consumption in low, but you are guaranted to work in transaction boundaries. If problem is due to use of Hibernate instead of plain JDBC you can think to use a Stateless session or flush()/clear() session manually; 1mil record for a database is not a big number Unfortunately ORM is not the best choice when you have large amout of data. My 2 cents, I'm quite new with Spring-batch as you.

Postgresql batch update with Spring. How to write a function with no return value
As I understand it your problem is that PostgreSQL will add a row to the result set even though your function didn't return one. A quick test showed that, in fact, these are returning a null from PostgreSQL. What I do (and I realize this may not be the Spring way) is to have a function that does what I need it to do, and returns a useful value. Then I take that value and use it for sanity checking purposes. I might, for example, return the total number of rows updated (or perhaps the most recent version of the parent-most row) and hand that back to the application to use. However, yes, you will need to find another way to do this.

Why spring batch itemWriter has method write with list of data
The answer is in this sequence diagram from the Spring Batch documentation. If this is not clear enough, the documentation (again!) explains that Spring uses a chunck oriented processing style: Spring Batch uses a 'Chunk Oriented' processing style within its most common implementation. Chunk oriented processing refers to reading the data one at a time, and creating 'chunks' that will be written out, within a transaction boundary. Actually the Spring Batch documentation is quite good. I would recommend to read it if you are starting with Spring Batch.

how to write a batch file to execute TCL files
Um, are you sure you're writing Tcl? This isn't the syntax for Tcl. What you might be looking for is: for {set i 1} {$i < 100} {incr i} { set ns [new Simulator] .... ....(my NS code) .... $ns run } You use braces everywhere. The only time I can think of using brackets is for arrays, but I don't think I know Tcl deep enough to ascertain this, and your start conditions, test and next commands are in their own braces and incr i is equivalent to i++. Now, new is not a built-in function in Tcl. Do you have a proc named new somewhere? If you don't, then you'll get errors.

Spring batch one reader multiple writers
What do you mean by "multiple writers"? What you are trying to achieve seems NOT multiple writers, but a single writer with multiple-threads. To be clear, when we are talking about "multiple writer", we mean a reader read a chunk, and need to do different kind of "writing" for the chunk. e.g. you may have a PlayerRecordReader which read Player from somewhere, and you have PlayerDbWriter and PlayerFileWriter which writes to DB and File. Multiple writer are not for distributing the load. For case that you want the writing to be done in parallel, what you need is a single writer (of course you need to make it thread-safe) and using executor in your step definition. This page in Spring Batch give you clear instruction on how to do it. http://static.springsource.org/spring-batch/referenc

Liferay-Spring MVC portlet importing multiple .js files
Your references are relative to your web application context references, which normally is the portal ROOT context including the portlet instance and some other dependent constructs (the related LR theme) in this case and not the portlet (your application) context which you assume. So, the solution is to use a portal instance specific global variable with the prefix in front of your path definitions. To achieve this you have to construct this path before you render your HTML page content. This is usually achieved using some Liferay utility classes e.g. in case of a JSP like this: <link href="<%= PortalUtil.getStaticResourceURL(request, request.getContextPath() + "/css.jsp", portlet.getTimestamp()) %>" Apparently, in case you do not have server side scripting like the JSP (BTW w

Also, you should check to make sure that row contains enough elements before executing: if len(row) >= 10: #use first ten values in row, if there are at least ten cursor.execute("INSERT ...", row[:10]) You currently have your insert statement listed as two strings next to each other. This has the effect of joining them together with no space in between. You may want a space before "VALUES".
