Compile and run with javasci v2
How to compile a Java application using Javasci v2
Description
To compile a Java code based on Javasci v2, it is only necessary to have org.scilab.modules.javasci.jar and org.scilab.modules.types.jar defined in the classpath.
For example, with the code defined in the example of this page, the command would be:
on Linux/Unix/MacOSX:
$ javac -cp $SCI/modules/javasci/jar/org.scilab.modules.javasci.jar:$SCI/modules/types/jar/org.scilab.modules.types.jar
BasicExample.java
on Windows:
D:\> javac -cp %SCI%\modules\javasci\jar\org.scilab.modules.javasci.jar:%SCI%\modules\types\jar\org.scilab.modules.types.jar
BasicExample.java
To run Scilab, there are a few other things to set up.
Some global variables must me set:
SCI - Path to Scilab files
Linux/Unix/MacOSX:
In the binary version of Scilab, SCI will point to /path/to/scilab/share/scilab/
In the source tree of Scilab, SCI will point to the root of the source tree /path/to/scilab/source/tree/
Windows
path of scilab root directory:
set SCI=C:\program files\scilab-XXX
LD_LIBRARY_PATH - Paths to libscilab.so, libscitypes.so and libjavasci2.so (or .jnilib...)
Linux/Unix/MacOSX:
In the binary version of Scilab, SCI will point to /path/to/scilab/lib/scilab/
In the source tree of Scilab, SCI will point to the root of the source tree /path/to/scilab/modules/javasci/.libs/, /path/to/scilab/modules/types/.libs/ and /path/to/scilab/.libs/
Windows: Path to libscilab2.dll, libscitypes.dll and javasci.dll
equivalent to LD_LIBRARY_PATH on Windows is PATH
set PATH="%SCI%\bin";%PATH%
To launch the Java Application, you can either provide them with environnement variable
Linux/Unix/MacOSX:
LD_LIBRARY_PATH=/path/to/libjavasci/ SCI=/path/to/scilab/ java -cp modules/javasci/jar/org.scilab.modules.javasci.jar:modules/types/jar/org.scilab.modules.types.jar:. BasicExample
SCI=/path/to/scilab/ java -Djava.library.path=/path/to/libjavasci/ -cp modules/javasci/jar/org.scilab.modules.javasci.jar:modules/types/jar/org.scilab.modules.types.jar:. BasicExample
or with the arguments
Windows:
set SCI=c:\program files\scilab-XXXX
set PATH="%SCI%\bin";%PATH%
D:\java -cp "%SCI%\modules\javasci\jar\org.scilab.modules.javasci.jar";"%SCI%\modules\types\jar\org.scilab.modules.types.jar";. BasicExample
Optional options to launch java : -Djava.compiler=JIT
-Xmx256m
(With these arguments, you start javasci with same initial options like the standard scilab).
Note that two environnement variables are taken in account for specific needs:
SCI_DISABLE_TK=1
Disables Tk (Tcl's GUI)SCI_JAVA_ENABLE_HEADLESS=1
Launch Java in headless mode (no AWT/Swing)
Examples
// A simple Java example // javasci v2 // Filename: BasicExample.java import org.scilab.modules.javasci.Scilab; class BasicExample { public static void main(String[] args) { try { Scilab sci = new Scilab(); sci.open(); sci.exec("a=cos(%pi)*sin(%pi^2);"); } catch (org.scilab.modules.javasci.JavasciException e) { System.err.println("Could not find variable type: " + e.getLocalizedMessage()); } } }
