Win64com.dll: Installation, Troubleshooting, and Updating Tips for Java and Windows 7

At one point the RXTX library included drop-in support for using the javax.comm api. I'm not sure if it still does, but the main change then to use the "native" RXTX packaging was primarily just a package name change.

Windows 7 java win64com.dll

I've integrated RXTX libraries into some of my earlier projects and i found out this bug it has while working with comm ports under windows, so you might want to check this first before going into some serious app design. Communication works fine, never had any problem with that, but once you open the port you cannot close it and reopen, if you use method provided for closing port, your app just hangs, no exception no nothing. I found later the same behavior described by users on web, but never really found the solution to this problem. Again, this might help you save some time, check it first.

i tried the RXTX binary for 64 bit and i was able to communicate with my device on some level... but... there were other problems as my application referenced a version of the jpos library that internally was using the comm-api (had import javax.comm.*... in some Serial...Listener class)....

I was getting the error "The module may compatible with this version of windows" for both version of RegSvr32 (32 bit and 64 bit). I was trying to register a DLL that was built for XP (32 bit) in Server 2008 R2 (x64) and none of the Regsr32 resolutions worked for me. However, registering the assembly in the appropriate .Net worked perfect for me.C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe

2. replace the following files in the following directories:[-win32com.dll-] should be copied to the following directories:%JAVA_HOME%/bin == C:\Program Files\Java\jdk1.5.0_10\bin%JAVA_HOME%/jre/bin == C:\Program Files\Java\jdk1.5.0_10\jre\bin%windir%/System32 == C:\windows\system32Here is how to copy the file to the above directories:a. click startb. click runc. type in one of the above directories in the textfield and hit ENTER, this will pop-up a window directed to the specified directory. if this does not work, this means that your windows system environmental variables for java is missing.d. copy the file to that directory.

[] should be copied to the following directories:%JAVA_HOME%/lib == C:\Program Files\Java\jdk1.5.0_10\lib%JAVA_HOME%/jre/lib == C:\Program Files\Java\jdk1.5.0_10\jre\lib

I am trying to do it with comm.jar(your win version but for linux). You know, that* got the same functions as your javax.comm. Is it posible to findit for linux. Just that properties. In properties, there is a win32 and so... But, it is not so important for me to work with javax.comm, I am a biginner. :)

I installed as per your instruction. But it is not working for me. What OS you are using?I am on Windows Vista. Is it possible to access direct IO from the user-mode? as per my knowledge, from windows XP onwards we need a SYS file to access the IO directly. Can you help me out?

However, from the error you posted, it seems that you java compiler can not access the library to identify the ports on your machine. I suggest doing the following:1. search Google, use keyword: java.lang.NoClassDefFoundError: javax/comm/CommPortIdentifier

Caught java.lang.ClassNotFoundException: com.sun.comm.Win32Driver while loadingdriver com.sun.comm.Win32DriverError loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.pathCaught java.lang.UnsatisfiedLinkError: com.sun.comm.SolarisDriver.readRegistrySerial(Ljava/util/Vector;Ljava/lang/String;)I while loading driver com.sun.comm.SolarisDriver

Caught java.lang.ClassNotFoundException: com.sun.comm.Win32Driver while loading driver com.sun.comm.Win32DriverError loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.pathCaught java.lang.UnsatisfiedLinkError: readRegistrySerial while loading driver com.sun.comm.SolarisDriver

what operating system are you using? I tried this on my 64bit Vista machine and it did not work, however, this did work previously on a 32bit windows XP. I think these drivers are only for 32bit systems.

example:google keyword search: Caught java.lang.ClassNotFoundException: com.sun.comm.Win32Driver while loading driver com.sun.comm.Win32DriverCaught java.lang.ClassNotFoundException: com.sun.comm.Win32Driver while loading driver com.sun.comm.Win32Driver

you need to things to start programming in java language.1. an IDE (editor) you could use the notepad in windows as long as you give your file the .java ext. I personally use Netbeans IDE from or you could use Eclipse from

sorry friend, but I do not have a sample code to send sms.1. you could search google for sample code. use the following search word: java code: sms -> =java+code%3A+sms&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a

i m facing this exception when i run my java app..i cant undstnd wats happng cz at one instance it runs perfectly but nxt time it dsnt..and den after it dsnt run for a long period of time..i hvnt found ne solution yet pls provide one.

1. first line of errors says that COM4 is being used by Unknow windows Application. before you run your java appley, you need to close any software that uses COM42. if you look through the comments on this post you will notice couple of codes samples. you should be able to tailor them to your needs.

The Windows UI API creates and uses windows to display output, prompt for user input, and carry out the other tasks that support interaction with the user. Most applications create at least one window.
