Eclipse jdt compiler/tomcat

Question

Hi all,
this question is for those familiar with the eclipse jdt compiler.
Im my web application i'm trying to dynamically compile a java file that i'm saving in a dir under my webapps folder say "mydir"
for the comipaltion i'm using the eclipse jdt compiler but to get it work i need to specify the classpath argument for the Main.compile() method to work.
now what is the default classpath of tomcat server ?
or saying it in other way what should be the classpath i should use as arguments in Main.compile() method of jdt ?
thanking you.

Answer 1

well let me explain this more :
i'm using the following code for dynamic compilation :
ByteArrayOutputStream baosMessages = new ByteArrayOutputStream();
          ByteArrayOutputStream baosWarnings = new ByteArrayOutputStream();
StringBuffer warnings = new StringBuffer();
String classpath ="";
//           Start compilation using jdtcore
          boolean compilationStatus = org.eclipse.jdt.internal.compiler.batch.Main
                .compile("-1.5 -source 1.5 -warn:" + warningSetting + " "
             + classpath + file ,
             new PrintWriter(baosMessages), new PrintWriter(
          baosWarnings));
StringBuffer compilerMessages=new StringBuffer();
          long time1 = System.currentTimeMillis();
          public  void compile() throws Exception {
          BufferedReader br = new BufferedReader(new InputStreamReader(
                new ByteArrayInputStream(baosMessages.toByteArray())));
          while (true) {
             String str = br.readLine();
             if (str == null) {
                break;
            // this._logger.info("/javac/ " + str);
             compilerMessages.append(str+"\n");
          BufferedReader brWarnings = new BufferedReader(
                new InputStreamReader(new ByteArrayInputStream(baosWarnings
             .toByteArray())));
          while (true) {
             String str = brWarnings.readLine();
             if (str == null) {
                break;
             //this._logger.warning("/javac/ " + str);
             compilerMessages.append(str+"\n");
             warnings.append(str+"\n");
          System.out.println(compilerMessages.toString()+"\n\n"+warnings.toString());
          System.out.println((time1 - time0) + " milliseconds, "
                + (compilationStatus ? "success" : "failure"));
     }Now when i run the servlet containing above code the result of compilation tells me :
No such directory : null
i'm suspecting i'm missing the class path . is that true ?
can u help ?
