Before you install

Before you install you need to check these tools:

A Linux based OS
Python >= 3.8 (For Python 3 application)
Python 3 development API (for Python 3 application)
gcc >= 9.4.0
cmake >= 3.16.3
make >= 4.2.1
git >= 2.25.1
execstack >= 1.0 (for Java application)
Java SDK development API (for Java application)
Node JS >= v16.20.2 API (for Node JS)

Downloading

git clone https://github.com/devfabiosilva/witsml21parser.git

Compiling

witsml21parser needs libbson library to be compiled. For first time compiling you need to download and compile dependencies first.

There are two static dependencies:

• libbson
• WITSML 2.1 - ETP validation schemas C code

- Compiling libbson third-party library

make install_bson

For multi-threading fast compiling use -jN option e.g:

make -j12 install_bson

- WITSML 2.1 - ETP validation schemas C code

make pre pre_shared

For multi-threading fast compiling use -jN option e.g:

make -j12 pre pre_shared

- Compiling WITSML 2.1 to BSON parser

After compiling libbson third-party library and WITSML 2.1 - ETP validation schemas C code just type:

make

For multi-threading fast compiling use -jN option e.g:

make -j12

Executing

Just type:

./cws <FILE_NAME>

E.g:

./cws BhaRun.xml

It will convert BhaRun.xml to BhaRun.bson file

- Compiling WITSML 2.1 to BSON parser for Java/Kotlin

To compile native library for Java/Kotlin just type:

make jni

For multi-threading fast compiling use -jN option e.g:

make -j12 jni

Executing Java WITSML 2.1 to BSON parser

Before you run your code you MUST set native library environment.

• Go to Java sources folder
• Execute shell script:

source env.sh

• Open with your favorite IDE and run Java code here
• Run Tests and Aplication

SAMPLE APP jwitsml21cmd-1.0.jar

This app shows how to use WITSML 2.1 BSON parser in Java/Kotlin

Before use

You need to compile JNI

cd <WITSML 2.1 BSON PARSER PROJECT FOLDER>/
make jni

File libjwitsmlparser21.so must be in root project folder.

Compile Java library with maven

cd <WITSML 2.1 BSON PARSER PROJECT FOLDER>/Java/library
mvn -U clean install

Running

cd <WITSML 2.1 BSON PARSER PROJECT FOLDER>/Java/sampleApp
source env.sh
java -jar jwitsml21cmd-1.0.jar <WITSML 2.1 XML FILES>

make nodejs && cd $(pwd)/NodeJS && source env.sh

Running

In your NodeJS folder:

node app.js

Executing Python 3 WITSML 2.1 to BSON parser

BENCHMARKS

Primary benchmarks in Java had been shown that WITSML 1.4.1.1 parsing objects are 56 % faster than JAXB in Java application.

JAXB only parses XML objects and store their values in respective Java objects. In other hand, WITSML BSON parser not only parses XML objects in C structs but it creates BSON objects, adds objects to BSON, serializes it and parses it to Java native byte object.

But wait! How is WITSML BSON parser faster than JAXB doing more stuffs?

Answer is simple.

• Less allocation/reallocation in memory
• Referencing objects instead create and copy
• gSoap optimization on parsing XML to C structs. See some interesting GENIVIA articles here
• Recycled alloc'd memory
• Low memory usage
• Only two library dependency (gSoap and libbson)
• No garbage collector on parsing objects
