How to port AltibaseDialect

This document describes how to port AltibaseDialect to Hibernate to work with Altibase.

Hibernate full build

If you use the hibernate full build command as below, hibernate core library file containing AltibaseDialect.class will be created and detailed explanation can be found here.

git clone https://github.com/ALTIBASE/hibernate-orm.git
cd hibernate-orm
git checkout proper branch(ex:5.1)
./gradlew clean build

AltibaseDialect manual porting

You can compile only AltibaseDialect-related classes and add them to existing libraries without having to build hibernate entirely.

Hibernate library download

The Hibernate official distribution site provides hibernate core library for each version. The library provided by the Hibernate official distribution site does not include AltibaseDialect.class and should be repackaged and included.

AltibaseDialect.java compile

The AltibaseDialect.java file for Hibernate version can be downloaded from the link below. Starting with Hibernate 4.2, you need to compile with AltibaseLimitHandler.java.

  1. hibernate jar uncompress

    Move the hibernate-core-x.x.x.Final.jar file from the downloaded Hibernate library file to the directory where the java file is located and uncompress it.

     mv hibernate-core-x.x.x.Final.jar to-the-java-file-directory
 cd to-the-java-file-directory
 jar xvf hibernate-core-x.x.x.Final.jar

  2. Compile AltibaseLimitHandler.java, AltibaseDialect.java and SequenceInformationExtractorAltibaseDatabaseImpl.java files.

     javac -d . -cp . SequenceInformationExtractorAltibaseDatabaseImpl.java
 javac -d . -cp . AltibaseLimitHandler.java
 javac -d . -cp . AltibaseDialect.java

  3. When compilation is completed, the following class files will be created under the current directory.

     ./org/hibernate/dialect/AltibaseDialect.class
 ./org/hibernate/dialect/pagination/AltibaseLimitHandler.class
 ./org/hibernate/tool/schema/extract/internal/SequenceInformationExtractorAltibaseDatabaseImpl.class

  4. Delete the *.java files or move them to another directory so that the Altibase Dialet java source is not included in the jar file.

Port the AltibaseDialect class to a Hibernate jar file

Make a new jar file using the newly compiled AltibaseDialect classes.

jar -cvfm hibernate-core-x.x.x.Final.jar META-INF/MANIFEST.MF .
