how to generate documentation of jfreechart using ant

Question

I am using jfreechart in my project. No documentation is provided. However a build.xml is provided which can generate documentation. I have downloaded ant 1.8.2 and installed in c:\\ant\\ant 1.8.2. from CMD prompt, when i type ant javadoc, i get the error saying: Unable to locate tools.jar. Expected to find it in C:\\Program Files\\Java\\jre6\\li b\\tools.jar Buildfile: build.xml does not exist! Build failed

I have pasted my build.xml file into c:\\ant\\ant 1.8.2. Just to tell you all, i have jre 6 in C:\\Program Files\\Java\\jre6. I have also set environment variable path to c:\\ant\\ant 1.8.2\\bin. Where am i doing it wrong? can it be done? Thanks in advance

Ensure that you are in the directory that contains the build.xml file when you run ant javadoc .

Rather than putting the build.xml file into your ANT install directories, install it by seting up your environment so that you can run ANT from anywhere . Then, CD to the directory that contains the build.xml and execute ant javadoc .

When you execute ANT, it expects to find a build.xml file in the directory that you are executing from, unless you specify a buildfile using the -buildfile option.

To make Ant use a build file other than build.xml, use the command-line option -buildfile file, where file is the name of the build file you want to use.

The warning about tools.jar is because you are running with the JRE, rather than a JDK. If you aren't compiling Java files, then you probably don't have to worry about it. ANT will run the majority of the tasks just fine using the JRE.
