A technique for enhancing the startup operation of a user application within a client server network. At least the client is running software in JAVA language. Java Archive (JAR) files needed for startup are housed in the server. Rather than hard code the Jar files which makes upgrades difficult, embodiments of the present invention employ two applets operating on the same HTML page in the client. One applet, the Jar finder applet obtains all Jar files needed for startup from lists of Jar files stored in a directory which is also housed in the server. This directory is readily accessible to software developers allowing its easy modification by adding or removing Jar files or by substituting an entirely new directory. Another applet, the Jar user applet (or user application) receives the lists of Jar files from the Jar finder applet and thereafter obtains the actual Jar files from the directory in the server. After loading the Jar files, the Jar user applet launches the user application and the startup operation of the network is concluded.
