The JNI interface does not work very well. See http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII4.0/ptII4.0.1/doc/ptII4.0.release.htm or $PTII/doc/ptII4.0.release.htm
--start-- Limitations in JNI # The Interface to C actors using the Java Native Interface is not available via the Windows Installer (or Web Start). To use the JNI/Ptolemy II interface, you must download Ptolemy II as source files and compile. # The JNI user interface does not permit creation of new JNI actors. If you follow the instructions in JNIUtilities, then eventually you will get a NameDuplicationException. The resulting model will be missing <property name="output" class="jni.Argument" value="false,false,true,double"> </property> We are working with the original authors on a solution. In the short term, one workaround is to edit the xml file directly and add the appropriate property by hand. # JNI will not work with Hierarchical classes, subclasses, and inner classes --end-- Also, if Ptolemy exits when running the JNI model, then try using gcc-3.2.x in the Cygwin installer from http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII5.0/cygwin.htm which includes gcc-3.2.x The BASH: cant cd "Ptolemy/ptII4.0.1/" "Sun/AppServer/jdk/bin"..... error message you report makes no sense to me. Can you copy and paste the contents of the Cygwin bash window? To do this, highlight the text by left clicking in the Cygwin bash window and dragging the mouse over the text. Then hit the Enter key to put the text into the cut buffer. Note that to use the JNI interface, you must rebuild Ptolemy II from sources. $PTII/bin/vergil -jni should work for you, I just verified that it brings up JNI for me after I've installed Ptolemy II 4.0.1 from the Windows installer and then rebuilt. You might need to do export PTII=c:/Ptolemy/ptII4.0.1 $PTII/bin/vergil -jni For information about using JNI, see $PTII/jni/demo/jni/README.htm BTW - Don't include /cygdrive/c in your CLASSPATH. Java does not understand /cygdrive/c See "Cygwin Directory Mapping" in http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII4.0/ptII/doc/install.htm or $PTII/doc/install.htm Instead, you would do: CLASSPATH=c:/Ptolemy/ptII4.0.1 export CLASSPATH or export CLASSPATH=c:/Ptolemy/ptII4.0.1 _Christopher -------- hi I m trying to open vergil with jni interface enabled. 1.created a c file called "meaningOfLife.c" which contains double meaningOfLife(){ return 42.0 ; } 2. created a header file called "meaningOfLife.h" which contains extern "c" double meaningOfLife(); 3. $gcc -shared -o meaningOfLife.dll meaningOfLife.c 4. $ CLASSPATH=/cygdrive/c/Ptolemy/ptII4.0.1 $ export CLASSPATH 5. $ ./vergil BASH: cant cd "Ptolemy/ptII4.0.1/" "Sun/AppServer/jdk/bin"..... what may be the problem? even i have tried $vergil -jni, $PTII/bin/vergil -jni. It says no such command or file name. Could anybody please enlighten me. with luv, karthik venkatesh _________________________________________________________________ Manage information better.
