Hi Mortoza,

You just need create a class to Load any files that stay in your jar file.

That's the one way you can use:

- class name: LoadReport.java

// this is a subreport by name repassePeriodoResumido.jasper
  public static final String REL_REPASSE_RESUMIDO =
"/com/reports/repassePeriodoResumido.jasper";
  public static final String REL_REPASSE_ORGAO_AUTUADOR_RESUMIDO =
"repasseOrgaoAutuadorResumido.jasper";
        
  public String getURLFile(String arquivo) {
        Object obj = this.getClass().getResource(arquivo);
        if (obj != null)
                return ((URL) obj).toString();
        return "";
  }

in your main report create a parameter will receive the path of the sub-report.
For example: $P{SUB_REPORT}. In your class create a HashMap and insert the key
"SUB_REPORT" and, your value will be
loadReport.getURLFile(LoadReport.REL_REPASSE_RESUMIDO);

With this way you can load the sub-report.
