Hi i’ve been trying to install the library on Thinking in Java book 4th edition and i hit a very thick brick wall. I’ve done everything that the guide from the website told me to do and i still can’t get the library to work. From what i’ve read it seems that the problem is from the build.xml files. having no xml knowledge I am clueless about how I have to modify it in order for it to work. In both cmd and eclipse I am getting these error

c:\TIJ4\code\build.xml

Build Failed

c:\TIJ4\code\build.xml:59:J2SE5 required

Can anyone tell me what I should do ?

I am using eclipse if there is a simpler solution by using eclipse rather than ant please help me out. It’s been a week now and I still can’t make it work.

    The important thing to do is to realize that your ant file has a specific java requirement.

    Something to try that might fix this very easily : I believe you can remove any references to a specific JDK, and if you have a reasonably up to date JDK, the build will succeed.

    The definete fix : Look into the exact (line 59) of your build file, and try to satisfy the java version that line requires. Java is generally backwords compatible — something designed to run in J2SE5 should run in the latest JDK. Its not terribly difficult to update your JDK (just google for instructions on your OS).

    • The most common mistake I see is that people who have the java run time installed believe they also have the Java SDK as well.
