The Java interface
A Java component is included in the Server/Multi-user version of Barcode Tools for Crystal Reports.
The Java interface is provided by a Java servlet dbccr2d provided in the java\servlet folder of the 2D Barcode Tools for Crystal Reports installation directory. The source code for the servlet is included in the java\servlet_source folder and may be edited for changing the default barcode properties. Multiple servlets may be used where many different default barcode setups are required.
The Java servlet creates a Portable Network Graphic image of the barcode simply by referencing the servlet with suitable parameters, e.g. setting a graphic location to
http://myserver/dbccr2d?CodeType=1&Xunit=20&Caption=12345
generates the barcode image on the report.
Note that parameters passed in Java are case-sensitive.
