Spring Batch, is an open source framework for batch processing – execution of a series of jobs. Spring Batch provides classes and APIs to read/write resources, transaction management, job processing statistics, job restart and partitioning techniques to process high-volume of data.
The following Spring Batch tutorials and examples are tested with :
Spring Core 3.2.2.RELEASESpring Batch 2.2.0.RELEASE
P.S Spring Batch is part of the Spring Portfolio.

I am parsing(reading) an xml file(without root tag) that has multiple records through spring batch, but it is throwing an error. Please help me with the same. It works fine with the root tag but i want to parse it without root tag.

Hi can you add a tutorial on spring batch process read the input from ibm websphere mq and inserting into databse
Regarding Job Restart:::
can you add a tutorial on spring batch failed scenario(abnormal termination :jvm crash or power off) when the job is restarted then job start processing the input file where it has left off in the previous execution which was failed.
consider the scenario, parsing flat file line by line and printing or storing in database. Ex: input file contains 100000 records, 60000 records are processed successfully what i mean inserted into database successfully, but in the middle job crashes. I want to restart the batch and batch should start picking recrods from line 60001 (line number) but not from starting.
I need to implement a file locking mechanism such that while a particular process is reading the file, no other process is able to read it. Using FileLock from Nio Api is not working when I am deploying the application in a local server, can you provide a proper solution for this?
What other libraries you use in addition to those mentioned?
I have a error and I can’t fix
Error creating bean with name ‘step1’: Initialization of bean failed; nested exception is java.lang.reflect.MalformedParameterizedTypeException

Hi. Can you please help me how to configure a spring batch admin in spring based web application. i use JBOSS server to deploy the application.
Please help me on DB to DB batch process. I have an use case for simply reading from one Db and writing to another without any process. How do I achieve this without any intermittent RowMapper class. Please share me the use case. My writer class fails while inserting in to db.It says invalid SQL operation. How does the writer get to know from where it has to pick the data. Please share the sample for db to db without any DAO class.
I thought these collections were a great introduction to Spring Batch. I am still strugging to over-come the ORA error I encounter using Oracle for my job repository and I am trying to use the Spring Batch Admin from the instructions I found here: http://stackoverflow.com/questions/19840826/how-to-get-a-stable-release-of-spring-batch-admin And I have been successful at creating the appropriate batch-oracle.properties which I placed under the spring-batch-admin-sample (sub-directory within the set of things I downloaded per that link) under src/main/resources. I gather my problem is related to the transaction level for create, but I am uncertain where to provide whatever *.xml override or *.properties override as I see suggested in a few references regarding the: SQL
