In a Clover.ETL web project,
I put clover files into web\WEB-INF\clover directionary, it likes like this:
web
...+---WEB-INF
..........+---clover( *.grf)
.................+---connection (*.cfg)
.................+---metadata (*.fmt)

My test code like this:

String[] s = {request.getSession().getServletContext().getRealPath("/WEB-INF/clover/graphOrganLevel.grf")};

runGraph.main(s);

When I run this code in tomcat, It will throw a FileNotFoundException exception :
Graph definition file: E:\workspace\PMS\DEV\5.code\etl\web\WEB-INF\clover\graphOrganLevel.grf
java.io.FileNotFoundException: web\WEB-INF\clover\connection\pms.cfg
!!! Fatal error during graph initialization !!!

I can run this graph without any error in eclipse, but when in tomcat it will error .

Who can tell me what can I do to settle this relative path problem?

  I have settled this problem, I share my experience to all clover.etl develop friends:
  
  
  1. in action class , we can get project path:
  String projectpath = request.getSession().getServletContext().getRealPath("/");
  
  2.define parameter in graphOrganLevel.grf
  <DBConnection dbConfig="${projectpath}WEB-INF/clover/connection/pms.cfg" id="DBConnPms"/>
  
  3.invoice graph
  param = "-P:projectpath="+projectpath;
  fileName = projectpath+"WEB-INF/clover/graphOrganLevel.grf";
  String[] s = {param, fileName};
  runGraph.main(s);
  
  ok , now it can run without error.

  I find the why the tomcat will stop :
  I comment "System.exit(0);" in runGraph class, then the problem disappear.
  
  The source code like this:
  
  public static void main(String args[]) {
  ...
  if (finishedOK) {
  // everything O.K.
  System.out.println("Execution of graph finished !");
  //laq add comment: after I comment "System.exit(0)" the tomcat will not stop.
  //System.exit(0);
  } else {
  // something FAILED !!
  System.err.println("Failed starting graph !");
  //laq add comment: I think this line also neet to be commented.
  //System.exit(-1);
  }
  ....
  }
