Same problem. have you fixed this error?thx.

[pralitp]

To debug this we would need more information. Are you able to run the Model Interface .jar and is it using the same version of Java as GCAM is attempting to use?

Note you can manually change which Java is being used by GCAM by editing run-gcam.bat and changing:

REM SET JAVA_HOME=C:\Program Files\Java\jre1.8.0_101

To:

SET JAVA_HOME=<path to the correct version of Java>

In addition you should ensure you do not have any copies of jvm.dll into your exe directory. Some users have had this happen and causes a failure such as this.

Hi @pralitp, I am facing a similar issue. The error is something like this.

Configuration file:configuration.xml Parsing input files... Error occurred during initialization of VM Failed setting boot class path.

I did follow the steps you mentioned but still nothing.

[pralitp]

Could you post which version of Java you are using?

I haven't seen the "Failed setting boot class path." (which is different than "Unable to load native library: Can't find dependent libraries ") however some googling seems to indicate it might be related to special characters in the path to your GCAM workspace. You could test this theory out by moving the entire GCAM workspace to someplace simple such as C:\GCAM and see if still have the issue then.

[Amalsarfraz]

JDK 16.0.2.

And still no luck with the simple GCAM workspace. Still getting the same error.

[pralitp]

Could you try running Java directly from the Windows CMD prompt from within the "exe" directory of your GCAM workspace as follows to replicate the way GCAM will try to run it and see if it works:

java -cp XMLDBDriver.jar;../libs/jars/*;../output/modelinterface/ModelInterface.jar -Djava.system.class.loader=WildcardExpandingClassLoader XMLDBDriver --help

And maybe also just:

java -cp XMLDBDriver.jar;../libs/jars/*;../output/modelinterface/ModelInterface.jar XMLDBDriver --help

[Amalsarfraz]

Getting the following errors nows.

For the first one. Java HotSpot(TM) 64-Bit Server VM warning: Archived non-system classes are disabled because the java.system.class.loader property is specified (value = "WildcardExpandingClassLoader").

[Cermouth]

Hi there! Have you solved the problems?

[Amalsarfraz]

Hi, after doing everything pralitp said, I also set a system variable named JAVA_HOME.

[Cermouth]

Following @pralitp 's words, getting the following errors nows.

For the first one:

Different from @Amalsarfraz 's errors. Could anyone help? Thanks :)

Hi @pralitp , my problems are similar to @LyyDandelion 's. Error occurred during initialization of VM Unable to load native library: Can't find dependent libraries

I have set the JAVA_HOME and am sure the environmental variables are correct (because the model runs well on another computer).

Java version: JDK-17.0.2

Thanks for your help!

[Cermouth]

I deleted the "jvm.dll" in C:\Windows\System32 and the model worked. Thanks anyway for this issue!

[Fan-Ru]

(MACOS 12 system-M1 chip) I am using oracle JDK 17 x86 version because the arm64 version failed to run. But the ModelInterface requires other versions of JAVA. By following the instruments of the computer, a version of JAVA 8 update 333 was automatically installed in the Library/ Internet Plug-ins/.... After the installation, ModelInterface can be successfully opened. Yet the 'java -version' in terminal still shows as "17.0.3.1".
Then,I have the same problem as @Amalsarfraz , the error occurred as "Failed setting boot class path" when running the run-gcam.command , and after conducted @pralitp 's suggestion, the error still showed exactly like Amalsarfraz's. The environmental variable JAVA_HOME was already set as "JAVA_HOME=$(/usr/libexec/java_home)" . There is no non-english character in the work path. What can I do to solve this problem?

[Fan-Ru]

the .bash_profile was set as: JAVA_HOME=$(/usr/libexec/java_home) PATH=".$PATH:$JAVA_HOME/bin" CLASS_PATH=<GCAM workspace>/exe/XMLDBDriver.jar:<GCAM workspace>/libs/jars/*:<GCAM workspace>/output/modelinterface/ModelInterface.jar

[ecwood]

Has this been solved? I am similarly getting an error like this:

Parsing input files...
OpenJDK 64-Bit Server VM warning: Archived non-system classes are disabled because the java.system.class.loader property is specified (value = "WildcardExpandingClassLoader"). To use archived non-system classes, this property must be not be set
ERROR: XML Read Exception message is:

when I attempt to run gcam.exe on my Ubuntu 20.04 system.
