Conversion Features

  • All database connections in Informix 4GL application are migrated to JDBC connections with a correct connection command.
  • All DML statements are migrated to PreparedStatement in Java. In case when a database is different from Informix Ispirer MnMTK conversion tool automatically changes a DML statement accordingly to new database rules.


    Source Informix 4GL statement:

    1. SELECT zip FROM accounts

    Result after conversion into Java:

    1. mStmt = conn.prepareStatement("SELECT zip from accounts");
    2. Rs = mStmt.executeQuery();

    Examples from different databases:

    Source Informix 4GL statement:
    1. SELECT tab1.col_id
    2. FROM tab1, tab2
    3. WHERE tab1.tbl_name = "tab_name"
    4. AND tab1.br_id = "col_name"

    Results after conversion into Java with target database MSSQL:

    1. mStmt = conn.prepareStatement("SELECT tab1.col_id FROM tab1
    3. tab1.tbl_name = 'tab_name' AND tab1.br_id = 'col_name' ");
    4. Rs = mStmt.executeQuery();

    Source Informix 4GL statement:

    1. SELECT col2[2,2] FROM test_table;

    Results after conversion into Java with target database MySQL:

    1. mStmt = conn.prepareStatement("SELECT SUBSTR(col2,2,1)
    2. from test_table");
    3. Rs = mStmt.executeQuery();
  • Informix 4GL Modules to Java classes migration:
    • Main functions in the Informix 4GL application are migrated to Constructor class in Java.


      Source Informix 4GL :
      1. MAIN
      2. DEFINE
      3. i INTEGER,
      4. j INTEGER
      5. LET i = 3
      6. LET j = 5
      7. END MAIN

      Results after conversion into Java:

      1. import java.util.*;
      2. public class Main_func_4gl
      3. {
      4. int i;
      5. int j;
      7. public Main_func()
      8. {
      9. i = 3;
      10. j = 5;
      11. }
      12. }
    • Informix 4GL records are represented by Inner Class in Java. Every field in record is a property of inner class.


      Source Informix 4GL :

      1. LRRpt RECORD
      2. account LIKE accounts.account,
      3. name LIKE,
      4. addr1 LIKE accounts.addr1,
      5. addr2 LIKE accounts.addr2,
      6. addr3 LIKE accounts.addr3,
      7. city LIKE,
      8. state LIKE accounts.state,
      9. zip LIKE,
      10. phone LIKE
      11. END RECORD

      Results after conversion into Java:

      1. class Lrrpt_class
      2. {
      3. String account;
      4. String name;
      5. String addr1;
      6. String addr2;
      7. String addr3;
      8. String city;
      9. String state;
      10. String zip;
      11. String phone;
      12. }
  • Infromix 4GL forms to Java Swing migration:
    • For composing components our migration tool uses GridBagLayout class. So all your controls will be placed as grid in a Java application.
    • All static text goes to JLabel and all results in a field go to JTextField.
  • You can download more samples:
