OntoBuilder Instructions

In order to use the OntoBuilder tool you must follow these instructions:

If running it as an applet:

• You must have the Java Plug-in with a JVM version 1.4 or higher
• Download the tool libraries and copy them in the %JRE%\lib\ext, where %JRE% is the directory where the Java Runtime Environment was installed (usually C:\Program Files\Java\j2re1.4.0 for the JRE 1.4.0 on Windows)
• Download the keystore and copy it in your user home directory. On Windows it is usually in C:\Document and Settings\%USERNAME%, on UNIX is usually in the variable %HOME. Make sure the keystore has the following name: .keystore
• Download the policy file and copy it in your user home directory where you copied the .keystore file.
• Open the java.security file located in the %JRE%\lib\security directory. Add a line to the policy.url section. It should look something like the following:

  				# The default is to have a single system-wide policy file,
  				# and a policy file in the user's home directory.
  				policy.url.1=file:${java.home}/lib/security/java.policy
  				policy.url.2=file:${user.home}/.java.policy
  				policy.url.3=file:${user.home}/policy
  			

  The line in bold is the entry for the policy file downloaded in the previous step

If running it as a Java Web Start application:

• Install the Java Web Start with a JVM version 1.4 or higher.
• Download the tool libraries and copy them in the %JRE%\lib\ext, where %JRE% is the directory where the Java Runtime Environment was installed (usually C:\Program Files\Java\j2re1.4.0 for the JRE 1.4.0 on Windows)

If running it as a standalone application:

• Install the Java 2 SDK version 1.4 or higher.
• Download the tool libraries and copy them in the %JAVA_HOME%\jre\lib\ext, where %JAVA_HOME% is the directory where the Java 2 SDK was installed.
• Copy the same libraries in the %JRE%\lib\ext, where %JRE% is the directory where the Java Runtime Environment was installed (usually C:\Program Files\Java\j2re1.4.0 for the JRE 1.4.0 on Windows)
• Dowload the OntoBuilder.jar file. Once donwloaded, double click on it (or use java -jar OntoBuilder.jar from the command line) to run the tool.
