Java on a mac (OS X 10.3.5), continued from last post (with lj cuts)
Does anyone know what kind of java is on a mac (I've been asked, and don't know)?
(eg sun's java, ibm's java, ...)
In this post, I am including instructions for setting up java in order to be able to run things on our own computers as well as remotely on school's computers. But they are instructions for Windows users, and I am a mac user. So the question is, what do I need to do with the line in the build.xml file that says:
property name="java.runtime" value="${java.home}/jre/lib/rt.jar"/
For windows users, here are the instructions for downloading java:
1. Go to http://java.sun.com/j2se/downloads/index.html
2. Download the latest version of the Java 2 Standard Edition (J2SE) SDK (currently J2SE 1.4.2)
3. Run the downloaded file to install java
4. When the installation prompts for what components to install, click the "Change" button and
change the installation directory to: C:\j2sdk1.4.2
Then, what they have under /appl/j2sdk1.4.2 which is:
[use@name user]$ dir /appl/j2sdk1.4.2/
total 11364

How to setup Windows Environment Variables for Java
1. Go to the Windows Control Panel (Start->Settings->Control Panel OR Start->Control Panel)
2. Double click "System"
NOTE: In Windows XP, if you do not see "System" you might need to click "Switch to Classic View" first.
3. Click the "Advanced" tab
4. Click the "Environment Variables" button
5. Click "New" to add a variable
6. For "Variable Name" put:
JAVA_HOME
7. For "Variable Value" put:
C:\j2sdk1.4.2
8. Click the OK button
9. Find the variable "PATH" and click the "Edit" button
10. Add this to the end of the string for "Variable Value":
C:\j2sdk1.4.2\bin;C:\appl\ant1.6.2\bin
11. Click the OK button until you get back to the control panel
12. Close the control pane
So that in the end they can refer to this simple name in build.xml
Here is the build.xml code. NOTE: It's xml code, and to post here, I've replace ">" with ")" etc.
Here is where I need to know JAVADIR:

ANT TASKS
---------
all creates the "${classDir}" directory, compiles the code,
and puts the compiled classes into the "${classDir}"
directory.
batchrun run the program in batch mode. arguments can be passed
to the batch run by doing:
ant batchrun -Dargs="your arguments here"
see below about setting arguments on the command line
clean deletes the directory "${classDir}"
compile compiles the project and puts the compiled classes in
"${classDir}"
debug run the project in debug mode, piping the output to ${debugFile}
distjar creates a distribution jarfile in "${distDir}/${projectName}.jar"
parsereport parses an XML report file given by the F argument.
for example, to parse the report file "report.xml.00" do:
ant parsereport -Dargs="report.xml.00"
prepare prepares the project to be compiled (creates the
"${classDir}" directory)
projecthelp shows the help that is printed in the project
realclean deletes "${classDir}", "${libDir}", "${distDir}", and the debug
and report files
run run the program in GUI mode. you can pass arguments to the
model by doing:
ant run -Dargs="your arguments here"
see below about setting arguments on the command line
save create a jarfile with the contents of the current directory
and store it in:
"${saveDir}/projectName-today'sdate-timerightnow.jar"
for example, if one were created right now it would have
the name:
"${saveDir}/${projectName}-${today}-${timenow}.jar"
-------------------
OPTIONAL PARAMETERS
-------------------
Here is the list of buildfile parameters that can be changed:
NAME DESCRIPTION
----------------------------------------------------------------------
debugFile the debug file name
args a listing of the arguments to send to the java program
example:
ant run -Dargs="iPFN=dat/parameters1.xml nA=100"
debugFile and args could be used with any of the run commands
To set any of the above parameters do -DNAMEOFARGUMENT="value"
For example,
ant run -Dargs="iPFN=dat/parameters1.xml nA=100"
