Connecting to IBM Informix (JDBC)
This example illustrates how to connect to an IBM Informix database server through JDBC.
•JRE (Java Runtime Environment) or Java Development Kit (JDK) must be installed. This may be either Oracle JDK or an open source build such as Oracle OpenJDK. MobileTogether Designer will determine the path to the Java Virtual Machine (JVM) from the following locations, in this order: a) The custom JVM path you may have set in application Options; b) The JVM path found in the Windows registry; c) The JAVA_HOME environment variable.
•Make sure that the platform of MobileTogether Designer (32-bit, 64-bit) matches that of the JRE/JDK.
•The JDBC driver (one or several .jar files that provide connectivity to the database) must be available on your operating system. In this example, IBM Informix JDBC driver version 3.70 is used. For the driver's installation instructions, see the documentation accompanying the driver or the "IBM Informix JDBC Driver Programmer's Guide").
•You have the following database connection details: host, name of the Informix server, database, port, username, and password.
To connect to IBM Informix through JDBC:
2.Click JDBC Connections.
3.Next to "Classpaths", enter the path to the .jar file which provides connectivity to the database. If necessary, you can also enter a semicolon-separated list of .jar file paths. In this example, the required .jar file is located at the following path: C:\Informix_JDBC_Driver\lib\ifxjdbc.jar. Note that you can leave the "Classpaths" text box empty if you have added the .jar file path(s) to the CLASSPATH environment variable of the operating system (see also Configuring the CLASSPATH).
4.In the "Driver" box, select com.informix.jdbc.IfxDriver. Note that this entry is available if a valid .jar file path is found either in the "Classpaths" text box, or in the operating system's CLASSPATH environment variable (see the previous step).
5.Enter the username and password to the database in the corresponding text boxes.
6.Enter the connection string to the database server in the Database URL text box, by replacing the highlighted values with the ones applicable to your database server.
