Java CAPS 6/JBI Note 4 – File to File, with Java logic using Java EE SE

By Michael Czapski Sun No Comments »

The attached document explores the ability of Java CAPS 6/JBI and OpenESB to expose and execute Java-based logic as a JBI service. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution that reads an XML record from a text file, invokes java logic that operates on that record then writes the XML response record into a file.

There are errors in pictures on pages 12 and 13. The WSDL name in the pictures does not correspond to the name in the text. This error is corrected in revision 1.1 of the document, 04File2FielJavaEE_1.1.pdf. Thanks to Juraj Kazda for spotting the issue.

Java CAPS 6/JBI Note 3 – File-2-File with CSV to XML Decode/Encode

By Michael Czapski Sun 2 Comments »

The attached document briefly explores the Encoder aspect of Java CAPS 6/JBI and OpenESB. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution that reads comma-delimited record from a text file, ‘decodes’ then into XML and writes the XML-equivalent records into a file. The project is then extended to ‘encode’ XML records back to CSV format on output.

The focus is the practice of using JBI components not the theory of JBI.

This document addresses the integration solution developers, not developers of Service Engines or Binding Components.

The project uses JBI components only, that’s why it is just as good for OpenESB exploration as it is for Java CAPS 6/JBI exploration.

JBI (Java Business Integration) is not discussed to any great extent. JBI artifact names are used in discussion but not elaborated upon. Explanations are provided where necessary to foster understanding of the mechanics of developing integration solutions using JBI technologies in OpenESB and Java CAPS 6/JBI.

Java CAPS 6 and OpenESB are two of a number of toolkits that implement the JBI specification (JSR 208). When I use an expression like “In JBI …” I actually mean “In JBI as implemented in Java CAPS 6 and OpenESB …”. The same things may well be implemented differently in other JBI toolkits.

Java CAPS 6 “Revenue Release” is used and shown in illustrations. OpenESB can be used instead however the appearance of components shown in illustrations may vary somewhat.

I use Windows to develop these solutions and make no effort to verify that the solutions will run on other platforms.

The complete walkthrough is here.

Java CAPS 6/JBI Note 2 – Basic File-to-File projects with multi-record files

By Michael Czapski Sun No Comments »

This document is intended to help you get over the initial hurdles of exploring Java CAPS 6/JBI and OpenESB. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution, and a simple File to BPEL Process to File solution, with detailed step-by-step illustrations. Both solutions use inbound files with multiple records. The focus is the practice of using JBI components not the theory of JBI. This document addresses the integration solution developers, not developers of Service Engines or Binding Components. The projects use JBI components only, that’s why they are just as good for OpenESB exploration as they are for Java CAPS 6/JBI exploration.

Java CAPS 6/JBI Note 1 – Basic File-BPEL-File Project

By Michael Czapski Sun 1 Comment »

As implemented in OpenESB and Java CAPS 6/JBI, JBI at first put me off completely. I had no idea where to start and what to do. This was particularly annoying as I was reasonably effective in developing solutions using Java CAPS 5.x and did not look forward to trying to figure out how to do in OpenESB the same thing I already new how to do.

This document is intended to save you the anxiety and help you get over the initial hurdles.

Java CAPS 5.1, Implementing WS-Security 1.0 (2004) with JAX-RPC

By Michael Czapski Sun 2 Comments »

A couple of years ago I worked out how to supplement WS-Security infrastructure in Java CAPS 5.1.1 with additional services that WS-Security 1.0 (2004) supports, namely SOAP Message Security, X.509 Certificate Token Profile and Timestamp Token Profile. Together these provide Java CAPS solutions with XML Digital Signatures, XML Encryption, Sun Access Manager-mediated Username-based authentication and Timestamp support.

The attached document is 1 and a half years old. It makes statements about Username Token support in Java CAPS 5.1.1 being broken. Java CAPS 5.1.3 supports Username Token just fine so these statements are no longer true. Java CAPS 5.1.3 U2 adds a mechanism for hooking SOAP envelope handlers into the Java CAPS Web Services framework so what I did and described in the document can now be done differently – perhaps better and more transparently. I have not tried.

This material is provided on request on “all care but no responsibility” basis. Sun Java CAPS Support will not support this and neither will I. JAC-RPC from WSDP 2.0, which is at the heart of the implementation, is deprecated and has long since been replaced by WSIT/JAC-WS/Tango. Still, here it is if anyone is interested.

“JCAPS with JWSDP 2.0, Implementing WS-Security_1.1_JCAPS5.1.1.pdf” – discussion paper

Supporting materials are over 40Mb so I can’t post them to the blog. If anyone is interested says so.

Well, someone said so. The archive, WSSecSampleProject_1.2_JCAPS5.1.1.zip, is posted. Please understand that this is “all care and no responsibility” material. I don’t have the time to spend working through issues with individual people. It all worked at the time I put it together and on occasions since. It ought to work for you as well 🙂

Java CAPS 5.1 and Java CAPS 6 – Streaming Large FTP Transfers

By Michael Czapski Sun 34 Comments »

Transferring large payloads, on the order of tens or hundreds of megabytes, between a FTP server and a local file system, in either direction, requires selection of appropriate features of the Batch FTP and Batch Local File eWays, and tuning certain timing parameters.

Default timing parameter values result in timeout exceptions when transferring large payloads.

The Batch FTP eWay and the Batch Local File eWas are typically used to receive the entire payload before writing it out. This results in attempts to allocate memory many time the size of the payload being transferred and, for large files, causes memory exhaustion and application server failures.

Discussion in the attached document points out which timing parameters need to be tuned to facilitate transfer of large payloads. It also presents sample Java code that uses facilities of the Batch FTP and Batch Local File for streaming payload between the FTP server and the local file systems without using excessive amount of memory.

The material covered in the document was prepared using Java CAPS projects developed and tested in Java CAPS 5.1.0, exported, imported into Java CAPS Release 6 and tested again. It is expected that the code will work in all versions of Java CAPS from 5.1.0 up.

Java CAPS 5.1.3 – Sun SeeBeyond IS – Logging to additonal destinations

By Michael Czapski Sun No Comments »

By default, the Sun SeeBeyond Integration Server domain uses a single log to log all events, whether arising out of execution of the Integration Server or arising out of execution of Java CAPS solutions deployed to it. This log is named server.log and is kept in the <JavaVACPInstallRoot>/logicalhost/is/domains/<domainroot>/logs directory.

This note discusses how the Integration Server can be configured to deliver all or selected events to an additional log handler and how XML-formatted event information can be obtained. This note also presents some ideas on multiple logging destinations and notification.

Here is the Note itself: Java CAPS 51 – logging to additional destinations.pdf

Warning

The writing of this note, and the underlying development and configuration work, were prompted by repeated questions about logging in Java CAPS, in particular how it could be made to behave like it used to in the non-J2EE versions of the SeeBeyond EAI products. For these readers who are still waiting for the answer they like – there will be no such answer coming. It is not possible to configure logging for ‘your interface’ separately from logging for all other ‘interfaces’ since there is no notion of ‘your interface’ as a separate component in Java CAPS. There is no way to collect logging information pertaining to a specific project or deployment in such a way that all relevant information is collected, no information is lost and no information on unrelated components is included.
