Hey guys I'm having trouble opening jcalltracer, an open source program on sourceforge that reverse engineers a Java program into sequence diagram. I got error when I was trying to add the following to JVM -
java -agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5
Error -
Error occured during initialisation of VM
Could not find agent library C:\calltracer\jvmti\calltracer5.dll in absolute path, with error: Can't load IA 32-bit .dll on a AMD 64-bit platform
I am using Windows 7 x64 and I'm very sure that I installed the x64 version after checking the java sdk I downloaded and doing a java -version check. Any clues?
Looks like the calltracer5.dll has been compiled to work on a 32bit platform. You will need to recompile for 64bit.

I have downloaded "eclipse-jee-juno-SR1-linux-gtk-x86_64.tar.gz" from www.eclipse.org for linux-64 bit OS.
When i tried to run the installer, by double clicking on it. It showed the error
"A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java Virtual Machine was found after searching the following locations:
/home/shubham14/Downloads/Softwares/eclipse-jee-juno-SR1-linux-gtk-v86_64/eclipse/jre/bin/java
java in your current path."
I dont understand why this error has occured since i have jdk 14 already installed and its path is also set.
I recently created an application using the NetBeans IDE. I deployed it and created a jar file that runs perfectly on my computer and any computer that has the Java JDK installed, but when I try to run it on another computer that only has the JRE installed it says:
"Error: A JNI error has occurred, please check your installation and try again"
and then
"A Java Exception has occurred."
If you have JDK that you used to create jar with version1 and jre with version2 then you will encounter this kind of error.
For example:
If i used Java JDK 12 installed on my computer#1 to create jar.
At the same time, I had Java 8 (JRE) Installed on my friends computer.
So on my friend's computer it is not working because it has jre8..
I typed the follow commands to troubleshoot :
On computer#1 :
javac -version
// this gave me Java 12
On computer#2
java -version
// this gave me Java 8
In other words, my program is getting compiled with Java 12 (computer1)and I am trying to run with Java 8 on computer2.
To solve the problem, try running jar on same version of java used for development. Means match jdk and jre version.
I am using Idea with JDK1.8.0_201 and DCEVM-8u181-installer-build2. The installer seems to modify JDK without errors but when I try to run java -version or java -version -XXaltjvm=dcevm a system error pops up in my native language (I am using localised Win 7). The translation would be roughly "Entry point of procedure JVM_CopySwapMemory was not found in dynamically joined library jvm.dll".
What is the problem? Am I using incompatible versions of DCEVM and Java or does the problem lie elsewhere?
Hello im trying to use in a Project a dll generated with JNI.
i generated a 64 Bit dll but my project says %1 is not a valid win32 application
So i decided to generate a new DLL, but this time 32 Bit. I changed the Settings in my Visual Studio like i found i other posts, Configuration to Win32 and Target Machine to MachineX86.
this all works fine but when i try to launch the project with this DLL i get the same error. I checked the DLL with Dependency Walker and found out the DLL is 32Bit, but the included DLL's are 64 Bit.
So you guys are my last hope. Do you have any ideas ?
Notes: i can't change to Linux atm.
Visual Studio 2012
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
just read it but i already found my error, the problem was that eclipses changes it's installed JRE's when you switch workspace.
so in my testprogramm where i developed my 64bit libary worked. but not in the real project, where the installed JRE was a different one.
so if anyone has the same problem don't forget to check this
Please check your system PATH. Windows will attempt to load the first DLL it finds that matches the DLL's name. Windows doesn't check if the DLL is 32 or 64-bit, it will attempt to load it.
If you built a 32-bit DLL, then you're responsible for making sure that any dependent DLL is also 32-bit, and that Windows finds those 32-bit DLL's first.
I've installed Android standalone tools on Windows 7 32-bit, but when I am trying to run the android utility on the command line, the following error report is shown:
No suitable Java found. In order to properly use the ADT, you need a version of JDK installed (...)
I have Java properly installed in C:\Program Files\Java\JDK, and my JAVA_HOME is set to this path. (C:\Progra~1 - for ANT), PATH includes C:\Program Files\Java\JDK )
I have read on here in other posts that android utility simply starts find_java.exe, so when I start the program directly, I had this error:
The version of this file is not compatible with the version of Windows
you're running. Check your computer's system information to see whether
you need an x86 (32-bit) or x64 (64-bit) version of the program, and then
contact the software publisher.
It just seems like the SDK manager installs wrong (64-bit? I am not an expert on that, but the error seems like that) of Java finder for some reason.
Has anyone encountered a similar kind of error? What could some reasons for that be?
Thank you in advance
