Overview

1. Check out the source code or unpack the source zip file from sourceforge
2. Install the Development Environment
3. Configure the build by creating a compilation_tools.properties file.
4. Run Eclipse and load the project into eclipse
5. Open the build.xml file in Eclipse and run the default ant target

Repository Organization

Unpack the source archive zip file or check the files out of CVS into d:\jacob or some other familiar place. Source Java and JNI files are located in separate packages from the unit tests and the samples.

• docs: documentation
• jni: c++ code
• lib: libraries needed to compile unit tests
• release: a directory built by the ant script where jacob is constructed
• samples: sample programs
• src: Jacob Java source files
• unittest: JUnit 3.8.1 unit test programs. Run from the test target in build.xml
• vstudio: some out of date VC++ project files
• bulid.xml: the ant build script. It can be run from inside Eclipse

The Servlet examples that required j2ee libraries to compile have temporarily been removed.

Development Environment

• Microsoft Visual Studio 2013 and it's included library. (to C:\ProgramFiles (X86) in my case)
• Eclipse from www.eclipse.org as the Java IDE.
• Eclipse C/C++ plugin can be used for C coding in place of VC++ IDE.
• Java JDK 1.6 , latest available
• Install the V7.1A libraries that originally came with VS2010

Microsoft Visual Studio 13 supports 64 bit builds. so no additional tools are required.
Microsoft changed the location of the windows sdk (formerly known as platform sdk) after VC 8.0. https://en.wikipedia.org/wiki/Microsoft_Windows_SDK

Build Process

The ant process is driven off of a configuration file named compilation_tools.properties that describes the locations of the JDK and Microsoft C++ tools. The build.xml file in the root directory contains examples of the contents of this file.

There are two main ant targets.

• "default" executes the following steps when using the default target.
  • Build the Java code
  • Build the jni code
  • create the dll
  • create jar file
• "packageRelease" runs the above listed steps and then
  • builds the javadoc
  • builds a source zip
  • builds a binary zip with the javadoc

Eclipse Java IDE

Eclipse users have to do some minor tweaks to their project if they want to use the integrated build process. This is because the unit tests are files located in the "unittest" directory while the project source files themselves are in "src" the root directory. By default, eclipse will add the entire project as source. This messes up the package naming. In addition, the build directory should be set to be the same place the ANT build puts the compiled java classes. A couple small tweaks to the build path fix these problems:

Open up the project properties and go to the "Java Build Path" properties panel.

• Remove the root of the project from the build path
• Add folders samples, src and unittest to the build path in the Source tab.
• Exclude *.txt from each of the newly added folders.
• Set the default build output directory to jacob-project/release/java

Troubleshooting Build Problems

• Symptom: Build Failed can't find javac compiler. JAVA_HOME does not point to the JDK Problem: The java library is pointed at a jre insted of the jdk. Update Project..Properties..Java Build Path to point at the JDK
• Symptom: The jar is built but no dlls were compiled.

  Problem: compilation_tools.properties does not have the correct location for the Microsoft tools.

• Sympton: Can't find jni.h or can't find C++ compiler

  Problem: compilation_tools.properties configured incorrectly. Either paths are wrong or the separator is wrong. It requires two backslashes for a separator.

• Symptom: Ant fails with the message Could not create task or type of type: junit..

  Problem: junit.jar must be copied from this project to the $ANT_HOME/lib directory.

Running Samples and Tests

	-Djava.library.path=c:/dev/jacob/release/x86 
	-Dcom.jacob.autogc=false 
	-Dcom.jacob.debug=false 
	-Xcheck:jni

JUnit test programs can be individually run from inside eclipse or en-masse via the ant test target. Last Modified 10/2008 1.15
