Unable to launch the EarthMoversStochasticConformancePlugin

Spylft

Hi,

Sorry for asking so many questions in a short time.

When I try to launch ProM Package Manager, it outputs:

错误: 找不到或无法加载主类 org.processmining.contexts.uitopia.packagemanager.PMFrame

The Chinese means it can't find org.processmining.contexts.uitopia.packagemanager.PMFrame.

--------------------------

When I try to launch ProM with UITopia, it outputs:

Error occurred during initialization of VM

java.lang.Error: java.lang.ClassNotFoundException: org.processmining.framework.util.ProMClassLoader

Which I have solved before by change the jre to jdk1.8.0 from jdk18, but it doesn't work this time.

I searched in this website, but found many answer saying it is caused by the outdated files.

How can I fix this error?

Thanks

Hi,

Did you perhaps mix two versions of ProM?

Please check which files are there in the dist folder, and which files are actually mentioned in either the .bat file (I guess you're trying to start ProM using the .bat file, if not please let me know how you're trying to start it). The files mentioned in the .bat file should match the files in the dist folder.

Kind regards, Eric.

Hi,

I use SVN to download this plugin from https://svn.win.tue.nl/repos/prom/Packages/EarthMoversStochasticConformanceChecking/.

And I use eclipse to open this project, use Ivy to resolve dependencies.

After that, I use this configuration to run:

The first four figures for PMPM, the last two figures for PM.

But it output errors like above.

Did these steps wrong in anywhere?

Thanks

hverbeek

In the Classpath tab, is Ivy listed there? Like follows:

ProM should get the framework jar files from this Ivy folder.

Spylft

HI,

There is ivy in it, but have many jars in it too.

The PMPM is simiar.

But in another plugin, it have Classpath in PM and have Dependencies in PMPM. Why is this different?

Thanks

hverbeek

If you right-click the project and open its Properties, what do you see in the Libraries tab?

My guess is that you see different things here, and that you need to update this list.

Spylft

There are also jars in this tab. Need I remove them all from this tab and only leave Ivy and JRE System Library in here?

hverbeek

Yes, please remove all but the last two entries (Ivy and the JRE). Please also check the Projects tab. It should be empty, and the Source tab:

Spylft

After I remove them, it still doesn't work.

And the error outputs the same as before:

错误: 找不到或无法加载主类 org.processmining.contexts.uitopia.packagemanager.PMFrame

for PMPM

for PM

Spylft

Hi,

I get up and try again.

I work in a new workplace, and cleaned all ivy cache. Resolve the dependencies.

When run PM, it outputs:

Exception in thread "main" java.lang.NullPointerException

at org.processmining.contexts.uitopia.UI.main(UI.java:58)

--------------------------

When run PMPM, it start successfully, but outputs:

No packages were found. Please check your internet connection.

And in console it outputs:

[PackageConfigPerister] Context URL set to http://www.promtools.org/prom6/packages/

The URL is not complete.

How can I fix it?

Thanks

Hi,

I tried to use the method in other discusstion, added timeout threshold in ProM.ini:

#

# Timeouts used when trying to get a file from the repository.

# Setting a timeout to 0 means no timeout will be set.

CONNECT_TIMEOUT = 0

READ_TIMEOUT = 0

But it still doesn't work, outputs as above the same.

Spylft

Hi,

Here is my files of this project at this time. Can you please check the setting files? I really don't know why another ProM plugin project can run successfully but this project can't launch in the end.

EarthMoversStochasticConformanceChecking.zip

Spylft

When I switch the JRE to jdk-18.0.1.1 and run PM, it outputs new error message:

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "org.processmining.framework.boot.Boot.AUTO_UPDATE" is null

at org.processmining.contexts.uitopia.UI.main(UI.java:58)

Shows that org.processmining.framework.boot.Boot.AUTO_UPDATE is null. Is it the key error? But what caused it? have I download the right files? Like org.processmining.contexts.uitopia.UI.java or others? How can I check it?

Spylft

Hi Eric,

I solve this problem in a special way: I copy this project's code and its ivy.xml's containing to another project's folder, and that project can run successfully. Now I can run this plugin in other project🤣.

Thanks for your greatful help!
