rxtx with Jabaco
Hi A1880,
thanks for the tip.
compiling is Ok now:
rxtx is loaded:
Listening for transport dt_shmem at address: Jabaco20832921x686
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
but then I get:

I have just downloaded jabaco and this is a very impressive program.
I am trying to add a serial port. I have read through this thread, and found the rxtxcomm program
I have extracted this to
C:\Program Files\Jabaco\serial\rxtx-2.1-7-bins-r2
and this directory contains several other directories, and it contains RxTxComm.jar
Next I have the code posted earlier.
but I get an error with the last line "Class CommPortIdentifier" not found.
I think this is importing the wrong file with 'Import javax#comm'. How do I import the correct serial port driver?
Many thanks.

Thanks for the quick response A1880!
When I get this working I'm going to write this up as a "step by step" guide as this is a little complex.
I've added the file, and I've added the folder.
With this code I get an error in the last line
error
Attached is a screen shot of the F1
1) The bottom entry is a link to the entire directory.
2) The second to bottom link is supposed to link to the .jar file.
3) It does not seem possible to check the checkboxes in the main list - only the sub boxes - see the screen capture.
4) A search at the bottom does not find the file RXTXcomm.jar - see the error message.
Any help here is most appreciated.

Thanks for the advice.
This is turning out to be extremely complicated. There are many variables so one has to work through them all:
1) I found this on wikipedia These files can also include a Classpath entry, which identifies other JAR files for loading with the JAR. This entry consists of a list of absolute or relative paths to other JAR files. Although intended to simplify JAR use, in practice it turns out to be notoriously brittle, as it depends on all the relevant JARs being in the exact locations specified when the entry-point JAR was built. To change versions or locations of libraries, a new manifest is needed.
So I copied these instructions
http://www.jcontrol.org/download/readme_rxtx_en.html
C:\Program Files\Java\jdk1.6.0_21\bin
and
and I have rxtxcomm.jar in
C:\Program Files\Java\jdk1.6.0_21\lib\ext
2) The instructions at the beginning of the program
The example earlier in this thread is
but there are suggestions to change this to something else. This website makes some suggestions
http://rxtx.qbang.org/wiki/index.php/Using_RXTX
But it says to change
Change the all occurences of the import javax.comm.*;
but we don't have that, we have javax#comm, so it is unclear whether to change this to
Import gnu#io
or some other syntax, eg Import gnu.io.rxtxcomm or Import gnu.io#rxtxcomm
I think I will use Import gnu#io because this autocompletes when you type gnu#
3) F1 and adding classes. I do not understand this. When you click on "Find Class", do you specify a .jar name, or do you specify just a filename, or a directory. What exactly is this searching for?
4) Adding a jar archive. F1 and "Add Jar-Archive" and it says it is searching for "files of type" "Jar-Archiv". Is this an extension? If so, I am not aware of an extension like this and a search does not find any files of this type. Scrolling through directories, the only files that are shown are ones ending in .jar. But above you said not to search for filenames, rather to search for classes. But a jar is an archive, and you can unzip and view the individual files with any zip program. So do we add the archive rxtxcomm.jar or not? I am assuming you do, because when I add this file, I get some very rapid messages on the screen about "importing".
5) This is my test code now
I split the line with the Dim and setting the value as there was a comment earlier about casting.
The error is on this line en = Cast(CommPortIdentifier.getPortIdentifiers(), CommPortEnumerator)
and it says "no rxtxserial in java.library.path
So I still think the error is that jabaco does not yet know where the library is.
Any advice would be most helpful. Kind regards.

Vielen Dank für deine Hilfe.
********** SUCCESS! ***************
I have got it working! It finds one parallel port, and three serial ports (two hardware, and one is a $2 USB to serial device).
Some of the answer came from here http://mango.serotoninsoftware.com/forum/posts/list/14.page
1) Put the .dll files in this directory C:\Program Files\Java\jdk1.6.0_21\jre\bin
The dll files are a) RxTxParallel.dll and b) rxTxSerial.dll
The "jdk1.6.0_21" part will change as Java is updated from time to time.
*** Very Important ***
do NOT put these files in the C:\Program Files\Java\jdk1.6.0_21\bin folder. Put them in the \jre\bin folder
2) Put the RxTxComm.jar in this folder: C:\Program Files\Java\jdk1.6.0_21\lib\ext and as noted in several discussion forums, you will need to create the \ext folder.
3) Type F1 in jabaco and "Add Jar Archive" and browse to this directory C:\Program Files\Java\jdk1.6.0_21\lib\ext and select the .jar file
4) To check that jabaco knows these files exist, down the bottom of that screen, in "Classname" type SerialPort and then check "Find Class". (You have to know what the name is to be able to search for it!! Searching for Serial will not work)
5) Use this code
The code on post 21 of this thread does not work for some reason.
The above code answers posts 24 and 25 on this thread
6) You can get the serial driver package here http://www.jcontrol.org/download/rxtx_en.html
Once again, thankyou so much to A1880.
Hopefully this post will help someone else in the future.
