First start

    Netsilon is delivered as a ZIP file. The product can be installed in any folder location (about 10 Mb).

    Presentation

    The application is given by 25 files with different targets:

• xml (vide.xml and web.xml): XML files for XMI import and Java deployment
• dtd (uml11.dtd and uml13.dtd): DTD for XMI import check
• new: model for empty project
• jar for Netsilon (gnu-regexp-1.1.4.jar, jh.jar, xalan.jar and xerces.jar): necessary for Netsilon execution
• jar for deployment (jakarta-oro-2.0.3.jar, mysql.jar and oracle12.jar): necessayry for deployments; may be copied into java generations
• Netsilon itself (Netsilon.jar): a java executable archive
• Netsilon help (NetsilonHelp.jar): an archive including integrated help
• kos files (jsp.kos, jspJdbc.kos, php3.kos, php3mSql.kos, php3msSql.kos, php3MySql.kos, php3odbc.kos, php3oracle.kos, php3postgreSQL.kos, php3sybase.kos and servlet.kos): XSLT files for final file generation

    You should not modify, delete or replace these files.

    Execution

    Netsilon is written in Java and can be used on any platform which runs a compatible Java virtual machine (1.3 compliant). ObjeXion recommends :

• Sun Java 2 Runtime Environment Standard Edition 1.3 (JRE) for Windows and Solaris(http://java.sun.com/)
• IBM Runtime Environment Release 1.3 (http://www.ibm.com/java/) for Linux and other platforms.

Notice: proper execution of Netsilon requires libraries, like Xerces, Xalan and others to access databases. An error message (such as "No class def found error"), at program start, or while reading or writing a project file, often indicates that a wrong library is taken. This happens typically with the Java VM for Windows from IBM. Check then if there are no overriding libraries.

    Netsilon requires memory resources. It is advised to specify the maximum amount of memory allocated to the virtual machine (most Java VM allocate 64 Mb by default). A good compromise is 2/3rd of the available memory. 128 Mb is a minimum, 256 is recommended. To specify the amount of memory to allocate, there is a non-standard option -Xmx???m, where ??? is the memory size in Mb. Refer to your Java VM documentation to find the supported options.

    Netsilon is delivered as a JAR executable file, as well as several XML files. If the Java VM supports the -jar command line option, use it o start Netsilon. If the VM does not support this option, run uci.uml.Main after having specified the absolute path to the jar file, in the environment variable CLASSPATH.

Examples of command lines

• with the jar option: 

java -Xmx256m -jar NetsilonInstallationPath/WebProject.jar

• without the jar option on Windows: 

set CLASSPATH=%CLASSPATH%;NetsilonInstallationPath\WebProject.jar 

java -Xmx256m uci.uml.Main

• without the jar option on UNIX: 

set CLASSPATH=$CLASSPATH:NetsilonInstallationPath/WebProject.jar 

java -Xmx256m uci.uml.Main

    Netsilon may be started with options as well. For instance, to specify the help option:

java -Xmx256m -jar NetsilonInstallationPath/WebProject.jar -help

The following command line options are available:

• help: displays the list of available options.
• big / huge: uses large fonts.
• nosplash: starts without splash screen.
• errorfile <FileName>: redirects the error output to the specified file. This feature may be used for problem isolation and resolution.
