Java Question Problem with the development of libraries to generate PDFs from CrystalReports

I've been trying to add the functionality of passing parameters to the jCrystalReports library
but once I compile it with SLC it shows me some errors so I have to add some packages


B4X: 
    #AdditionalJar: CrystalReportsRuntime.jar
    #AdditionalJar: log4j.jar
    #AdditionalJar: logging.jar

it works but when I run it, it displays other errors.

here I leave the code as I have it modified with a parameter



B4X: 
public void LaunchReportWithParameters() {

 
    BasicConfigurator.configure();
    Logger.getRootLogger().setLevel(Level.ERROR);
    try {
      if (REPORT_NAME != "" && USERNAME != "" && SERVER_NAME != "" && CONN_URL != "" && DB_NAME != "" && DB_CLASS_NAME != "") {
        ReportClientDocument reportClientDoc = new ReportClientDocument();
        reportClientDoc.open(REPORT_NAME, 0);
        reportClientDoc.getDatabaseController().logon(getUSERNAME(), getPASSWORD());
        reportClientDoc.getDataDefController().getRecordFilterController().setFormulaText(SELECTION_FORMULA);
         ParameterFieldController parameterFieldController = reportClientDoc.getDataDefController().getParameterFieldController();
        parameterFieldController.setCurrentValue("", "Prefijo", new String ("HN"));
        ConnectionInfo connectionInfo1 = new ConnectionInfo();
        ConnectionInfo connectionInfo2 = new ConnectionInfo();
        DatabaseController dbController = reportClientDoc.getDatabaseController();
        IConnectionInfo iConnectionInfo = dbController.getConnectionInfos(null).getConnectionInfo(0);
        Fields pFields = null;
        if (TRUSTED_CONN != "true")
          TRUSTED_CONN = "false";
        PropertyBag pb = new PropertyBag();
        pb.put("JDBC Connection String", "!" + getDB_CLASS_NAME() + "!" + getCONN_URL());
        pb.put("Trusted_Connection", getTRUSTED_CONN());
        pb.put("PreQEServerName", getCONN_URL());
        pb.put("Server Type", "JDBC (JNDI)");
        pb.put("Database DLL", "crdb_jdbc.dll");
        pb.put("Database", getDB_NAME());
        pb.put("Database Class Name", getDB_CLASS_NAME());
        pb.put("Use JDBC", "true");
        pb.put("Database Name", getDB_NAME());
        pb.put("Server Name", getCONN_URL());
        pb.put("Connection URL", getCONN_URL());
        pb.put("Server", getSERVER_NAME());
        connectionInfo2.setAttributes(pb);
        connectionInfo2.setUserName(getUSERNAME());
        connectionInfo2.setPassword(getPASSWORD());
        connectionInfo2.setKind(ConnectionInfoKind.SQL);
        int replaceParams = 4;
        dbController.replaceConnection(iConnectionInfo, (IConnectionInfo)connectionInfo2, pFields, replaceParams);
      } else {
        System.out.println("Some fields were not filled. REPORT_NAME, USERNAME, SERVER_NAME, CONN_URL, DB_NAME and DB_CLASS_NAME are required.");
      }
    } catch (ReportSDKException ex) {
      System.out.println(ex);
    } catch (Exception ex) {
      System.out.println(ex);
    }
  }

I have even tried to replicate the library by just copying the code without modifying it and still I can't run it.

EDIT:

If anyone else is interested, I solved this problem by adding java code to a new class

and making use of this function with "RuntMethod" I am attaching the compiled library for the use of

exporting Crystal Reports reports with parameters

and I also leave here the code of the class in case someone needs to add more parameters or any other thing.

How to use?

create a variable with the instance of CristalReportsB4j

and then call the GenerateOT() function with the following parameters

GenerarOT(REPORT_NAME As String, USERNAME As String, PASSWORD As String, SERVER_NAME As String, _
CONN_URL As String, DB_NAME As String, DB_CLASS_NAME As String, SELECTION_FORMULA As String, PARAM_NAME As String, _
PARAM_VALUE As String, TRUSTED_CONN As String, RUTA) where RUTA is the location where the pdf is to be saved exp.

B4X: 
Dim cr As CrystalReportsB4J
    cr.Initialize
    cr.GenerarOT("C:\Users\Macbook\Desktop\LIBRERIAS EDITANDO\jCrystalReports\ReportesHN\rptOrdenTrabajo.rpt", "YourUser","SecretPassword","HN-VSR-SQL01", "jdbc:jtds:sqlserver://192.168.1.92:1433/DTKDBHN","DTKDBHN","net.sourceforge.jtds.jdbc.Driver","937690","Prefijo","HN","false", "DetektorOT-"&"937690"&".pdf")

Remember that you need to have both JcrystalReports libraries or create a class with the following code
1719493670332.png


B4X: 
Sub Class_Globals


End Sub

Public Sub GenerarOT(REPORT_NAME As String, USERNAME As String, PASSWORD As String, SERVER_NAME As String, _
    CONN_URL As String,  DB_NAME As String, DB_CLASS_NAME As String,  SELECTION_FORMULA As String, PARAM_NAME As String, _
    PARAM_VALUE As String, TRUSTED_CONN As String, RUTA)
  
    Dim reportFormat As JavaObject
    reportFormat.InitializeStatic("com.crystaldecisions.sdk.occa.report.exportoptions.ReportExportFormat")
    Dim pdfFormat As Object = reportFormat.GetField("PDF")
  
  
    Me.as(JavaObject).RunMethod("ExportReport", Array(pdfFormat, RUTA ,REPORT_NAME,USERNAME,PASSWORD,SERVER_NAME,CONN_URL,DB_NAME,DB_CLASS_NAME,"{OrdenTrabajo.OrdenTrabajoID}="&SELECTION_FORMULA,PARAM_NAME,PARAM_VALUE, TRUSTED_CONN))
End Sub


Public Sub Initialize
End Sub
