There are some *.so files that come with the javax.comm distribution; they need to be installed properly. Check the documentation that came with your javax.comm product.

[Dhananjay Padalkar]

thanks
but i an not getting exactly

i will go through the documentation
if possible give exactly file name

[Rob Spoor]

Please Use Code Tags the next time.

Java is looking for a native library, which should have the name SolarisSerialParallel.so (you're running this on Solaris, right?).

[Dhananjay Padalkar]

no
i am using Microsoft platforms
Windows Xp SP2

[Ernest Friedman-Hill]

... ummm, OK. Then the problem is that you're trying to use a Solaris javax.comm implementation on Windows!

[Dhananjay Padalkar]

thanks

but what should i do now

help me out
it's very urgent,
i had to submit my project work

The download page for javax.comm at Sun's web site very clearly says:

Note: Sun no longer offer's the Windows platform binaries of javax.comm, however javax.comm 2.0.3 can be used for the Windows platform, by using it in conjunction with the Win32 implementation layer provided by the RxTx project. To use that, download javax.comm for the 'generic' platform (which provides the front-end javax.comm API only, without platform specific back-end implementations bundled). Then acquire the Windows binary implementation rxtx-2.0.7pre1 from http://www.rxtx.org.

So did you follow these instructions?

[Dhananjay Padalkar]

Dear sir
i had allready followed the setting of java home like this


comm.jar --- be placed in:
%JAVA_HOME%/lib
%JAVA_HOME%/jre/lib/ext

win32com.dll should be placed in:
%JAVA_HOME%/bin
%JAVA_HOME%/jre/bin
%windir%System32


RXTXcomm.jar --- placed in:
%JAVA_HOME%/jre/lib/ext
%JAVA_HOME%/bin

javax.comm.properties ---- placed in:
%JAVA_HOME%/lib
%JAVA_HOME%/jre/lib


rxtxSerial.dll ---- placed in:
%JAVA_HOME%/jdk/jre/bin
%JAVA_HOME%/jre/bin


even though the exception remains same

Is the error message exactly the same, i.e. is it still complaining about the Solaris native library? If yes, then you are still using the wrong version of the library. Make sure you use the right version, remove the wrong one from your system.

[Dhananjay Padalkar]

i had completely uninstalled java & relative path setting
& copied the files attached with in ZIP to the paths

comm.jar --- be placed in:
%JAVA_HOME%/lib
%JAVA_HOME%/jdk/jre/lib
%JAVA_HOME%/jre/lib/ext

win32com.dll should be placed in:
%JAVA_HOME%/jdk/bin
%JAVA_HOME%/jdk/jre/bin
%JAVA_HOME%/jre/bin
%windir%System32


RXTXcomm.jar --- placed in:
%JAVA_HOME%/jre/lib/ext
%JAVA_HOME%/bin

javax.comm.properties ---- placed in:
%JAVA_HOME%/jdk/lib
%JAVA_HOME%/jdk/jre/lib
%JAVA_HOME%/jre/lib


rxtxSerial.dll ---- placed in:
%JAVA_HOME%/jdk/jre/bin
%JAVA_HOME%/jre/bin
%JAVA_HOME%/jdk/bin


even though the same exception is there

"Caught java.lang.ClassNotFoundException: com.sun.comm.Win32Driver while loading driver com.sun.comm.Win32Driver
Error loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.path

what should i do now

[Dhananjay Padalkar]

i had jsut now again downloaded
RXTXcomm.jar from
http://www.rxtx.org/

& trying

for solution

It looks like you are still mixing parts of the Windows and the Solaris drivers. It looks like you don't have the Windows driver in your classpath, and you do have the Solaris driver in your classpath, which tries to load a native library for Solaris, which is obviously not what you want when you're running on Windows.

Are you sure you are not still using any of the JAR files from the Solaris version of the javax.comm package? What does the javax.comm.properties file contain?

Don't completely re-install Java, that won't help. Instead, concentrate on the problem that you're trying to solve.

[Dhananjay Padalkar]

the javax.comm.properties file contains -

#
# Drivers loaded by the Java Communications API standard extension
# at initialization time
#
# Format:
# Each line must contain ONE driver definition only
# Each line must be of the form:
# driver=<ClassName>
# No spaces or tabs in the line.
# ClassName must implement the interface javax.comm.CommDriver
# example: driver=Win32Serial
#
#
# The hash(#) character indicates comment till end of line.
#
# Windows Serial Driver
Driver=com.sun.comm.Win32Driver

[Dhananjay Padalkar]

is the property file can be used under Windows enviroment

[Dhananjay Padalkar]

is any answer to the exception
what should i d now
it's very URGENT

What should i do
can Uyou help me to get new versions of Comm.jar, win32com.dll, & javax.comm.properties

Why are you using the Windows driver for a Solaris environment? That will 100% guaranteed not work.

[Dhananjay Padalkar]

i am working in Windows Enviroment
OS : Windows Xp SP 2
JSDK 1.2.6

or if any new version of win32com.dll is available juts tell me i will download from the site

any think do you want to know so that i can clear them for easier to understand
