Installation
Zelix KlassMaster™ 23.0 is distributed in either a zip archive or tar.gz.
- The evaluation version is distributed as ZKMEval.zip or ZKMEval.tar.gz.
- The commercial version is distributed as ZKM.zip or ZKM.tar.gz.
- The full documentation is distributed separately as ZKMDocs.zip and ZKMDocs.tar.gz.
To expand the tar.gz archive in Unix use the tar then the gzip utilities.
The syntax is gzip -d ZKMEval.tar.gz then tar vxf ZKMEval.tar.
In Windows both the tar.gz and zip files can be expanded using WinZip.
When you expand the distribution archive, you should get
- the file ZKM.jar
- the file ZKM.class
- the file readme.txt
- the file license.html
- the file install.html (this file)
- the file defaultExclude.txt
- the file defaultTrimExclude.txt
Note that Zelix KlassMaster™ requires Java 8 (ie. JDK 1.8 or better) to run. However, it can process Java bytecode from versions 1.1 through to and including Java 23.
However, note that Zelix KlassMaster™ version 23 requires a newer version of a Java 8 JVM to run. If you use an Oracle JVM earlier than 1.8.0_152 then you may get a JVM crash due to HotSpot bugs.
The cleanest way to run Zelix KlassMaster™ is use the -jar parameter.
Alternatively, you can put ZKM.jar into the classpath. Note that it is not enough just to put the directory containing ZKM.jar into the classpath.
(The file ZKM.class exists as a separate file and as a file within ZKM.jar. The separate file exists purely to catch classpath errors and can be safely ignored.)
You run Zelix KlassMaster™ by telling Java to run the com.zelix.ZKM class. Typically you should give the JVM more than the default amount of memory to work with. If you use the -Xmx512m parameter then you will give the JVM 512MB of memory which should be adequate for most purposes. However, you should be sure not to give the JVM more memory than is physically available. Otherwise performance will deteriorate dramatically as the JVM starts to use virtual memory.
