Java(tm) Communications API Solaris Installation Instructions
Version 2.0.3
License
-
Ensure that the library libSolarisSerialParallel.so can be loaded.
You can do this
either by adding libSolarisSerialParallel.so to the environment
LD_LIBRARY_PATH
or
by copying libSolarisSerialParallel.so to /usr/lib.
Example: Assuming your current working directory is where you extracted
the distribution,
% setenv LD_LIBRARY_PATH `pwd`:$LD_LIBRARY_PATH
or
$ export LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH
or, if you have administrative privileges on your machine,
% cp libSolarisSerialParallel.so /usr/lib
-
If you are using JDK (not JRE) Add comm.jar to your classpath.
Example: If you don't have a CLASSPATH set currently,
% setenv CLASSPATH `pwd`/comm.jar
or, if you have something in your CLASSPATH already,
% setenv CLASSPATH `pwd`/comm.jar:$CLASSPATH
-
Copy the file javax.comm.properties to your <JDK>/lib
or your <JRE>/lib directory.
If you don't have write permission to <JDK>/lib or
<JRE>/lib,
you can keep
javax.comm.properties in the same directory as comm.jar.
The search order for
javax.comm.properties is:
-
<JDK>/lib
-
the directory that contains the first valid comm.jar that is included
in the classpath.
The javax.comm.properties file must be installed. If it is
not, no ports will be found by the system.
-
Make sure you have the JDK native thread package installed. This implementation
only works
with native thread. Look at http://java.sun.com/products/jdk/
for details.
-
You should now be able to run your comm application Example:
% java YourCommAppPkg.YourCommApp
Note: If you are using JDK 1.1.6, include the -native flag.
Example:
% java -native YourCommAppPkg.YourCommApp
-
Several serial port sample applications are provided with this release.
One of them is BlackBox.
To run BlackBox, first add BlackBox.jar to your classpath:
% setenv CLASSPATH BlackBox.jar:$CLASSPATH
then run BlackBox:
% java -native BlackBox
-
One sample driver NullDriver is included in the samples/NullDriver
directory.
This is useful for folks attempting to write a new driver for their
own hardware.
Running with the JRE (Java Runtime Environment)
Use the -cp option to the JRE to specify the path to the comm.jar file
and to your application.
% jre -cp /home/extra/comm.jar:/home/bin/BlackBox.jar
BlackBox
or, if using JDK 1.1.6
% jre -native -cp /home/extra/comm.jar:/home/bin/BlackBox.jar
BlackBox
The javax.comm.properties file must be in the same location
as the comm.jar file or no ports will be found.

Notes/Known Limitations
-
In the current implementation we do not support the notify methods listed
below:
-
SerialPort.notifyOnRingIndicator
-
SerialPort.notifyOnOutputEmpty
-
The get...() methods can only return what the Solaris driver believes the
state to be.
and the following signals are not determined properly as per the following
notes
-
getRI - Not supported under Solaris
-
getDSR - Not supported on SBUS (SPARC) systems because they use the
zsdriver,
and the zsdriver does not return the state of this pin.
-
In the current implementation we do not support port ownership contention
resolution across
multiple Java(tm) Virtual Machines. It also does not support uucp style
ownership contention
resolution.
-
Both parity errors and framing errors are reported as parity errors.
 - Support for parallel port is very limited.
- On Solaris platforms the handshake
mode needs to be specified for both the
input
and output mode on both the sending and receiving side for it to work properly.
