How do I add a jar file into the build path of the compiler?

Question

Hey,
I'm trying to import a jar file into the build path of the compilation process, but it does not find the packages or the classes that are in it.
I think I don't add it right...
          ArrayList<String> options=new ArrayList<String>();
          options.add("-d");
          options.add(targetDirectory);
          options.add("-classpath");
          for(String str:includeDirectory)
               options.add(str);
          if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call());
                ....and I've tried this way:
     public void setTargetDirectory(String targetDirectory) {
          this.targetDirectory = "-d " + targetDirectory;
     private void compile(Iterable<? extends JavaFileObject> compilationUnits) throws Exception {
          ArrayList<String> options = new ArrayList<String>();
          options.add(targetDirectory);
          String classPath="-cp ";// tried this also with "-classpath"
          for (String str : includeDirectory)
               classPath+=str+":";
          options.add(classPath);
     if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call())
          // throw new Exception("Compilation Error");
     }Thanks in advance,
Adam.

Answer 1

Thank you for your reply,
Q: Are there .class files in that directory in that jar file? (the compiler doesn't ( can't )) look for directories, it can just look for specific files , and scan to get a list of all files matching certain criteria. So if there are no class files, it will say the package doesn't exist, even if there is a directory, possibly containing other files.yes there are class files in the jar, the tree structure:
j2MeDataChunkGenerator_Plugin\(lots of class files)
META-INF\manifest.mf
and thats it.
, your code will only work on windows because other platforms use a different path separator. You should use java.io.File.pathSeparator not explicit ';" when building your classpath. (this is unrelated to your problem, but you should correct it)will do, thanks.
Q: Is that error in your post formatted by your own diagnostics? (we could possibly help you better if we didn't have to guess!!)I would not post my own error code, this text is generated by the compiler diagnostic.
{code}
     System.err.println(" Error details: " + diagnostic.getMessage(null));
{code}
Q: Is line 3 of ImageCroper_Editor.java (sic) an import statement? (we could possibly help you better if we didn't have to guess!!)it is an import error... didn't the error message stated that it is an import problem? wired, I'm sure before it did. anyway it is an import error.
Also you don't show us what the variable includeDirectory is in terms of type, and contents, that might be helpful. (we could possibly help you better if we didn't have to guess!!)It has only one String object: "D:\%Important Documents\WorkSpaces\PacMan\ApplicationManager\Plug-in\Data Chunk Designer.jar"
the last file on the classpath list.
Q: Have you proven this? that i did post, in this long line of text.
Q: Is the compiler finding other classes (in other packages) in that same jar file?No. all the class files are in the jar, they all have entries that start with "j2MeDataChunkGenerator_Plugin\*.class", and since I get 47 errors I guess it does not load any other class.
thank you for you comments, the problem with having these errors, is that I can't even get a piece of information where this error is coming from, only that it is an import loading error package not found, what does that mean? that the jar was not loaded in compilation(no error about this), that the jar is corrupted(no error about this), that the path is incorrect(it is correct I made sure), that there is no such package in the jar(There is), that the compiler does not load the package(does it even do that?), really I can't even guess why this happens, I've been at this on and of all day today, really annoying.
Thanks,
Adam.
