qflib- Download and installation

qflib comes in two flavors, one for JDK 1.1 with Swing 1.1 and one for JDK 1.2 and above. Both versions are essentially the same, the only difference being the location of the collection classes.

The collection framework is a part of the Java Foundation Classes (JFC). With the release of JDK 1.2 the JFC were integrated into the standard Java class library.

Since the collection classes are far superior to their predecessors Vector and Hashtable, use of them is widespread throughout qflib. SUN has released a JDK 1.1 compatible version of the collection classes under http://java.sun.com/products/javabeans/infobus/index.html#DOWNLOAD_COLLECTIONS. To use qflib with JDK 1.1, the collections.jar archive from the above release must be present on your CLASSPATH.

Simply ensure that the correct qflib jar archive for your environment is present on your CLASSPATH, i.e. qflib_11.jar for JDK 1.1 or qflib_12.jar for JDK 1.2 and above. In the case of JDK 1.2 it is also possible to simply copy qflib_12.jar into the jre/lib/ext directory of your JDK installation.

To test the installation execute
java de.qfs.lib.Version
This should print a short message stating the installed qflib version.

The latest version of qflib is always available from the qflib download page.
