Re: JNLPClassLoader cannot find class: ClassNotFoundException

Can you please send the logs of the time it runs and fails with OWS 3.0.0?

Will it be possible for you to provide a small example or allow us to run your Jnlp from our machine?

Re: JNLPClassLoader cannot find class: ClassNotFoundException

Can you provide us with a sample to reproduce the issue?

Can you try running with https://github.com/karakun/OpenWebStar ... 0.0-alpha2 and let us know if it worked?

Re: JNLPClassLoader cannot find class: ClassNotFoundException

Code: Select all

java.lang.ClassNotFoundException: javax.media.jai.JAI
com.sun.media.imageioimpl.plugins.tiff.TIFFImageMetadata
Does your app run with Java 17 in standalone mode?

Please check if these classes are supported by Java 17? You will have to export modules or find alternative libs.

Re: unable to launch jnlp File - Fatal: Read Error: Could not read or parse the JNLP file

Could not read or parse the JNLP file at 'file:/C:/Users/Harald/Downloads/accesscard%20(1).jnlp'
Please check if the Jnlp file exists. Also please remove blanks from the jnlp file name.

Re: unable to launch jnlp File - Fatal: Read Error: Could not read or parse the JNLP file

You seem to be using Icedtea-web and not Open Web Start. Please use Open WebStart and if that does not work send the log file. Please don't copy logs in the post.

Re: problem with log4j2

Thanks very much for sharing the solution. Would it be possible to provide a small snippet of your application which is using "some appender implementations which use PatternLayout class from log4"? We can then debug why OWS was not able to find classes with Log4J 2.17.1 and why it is work...

Re: InvocationTargetException

Just to confirm that when you run the jnlp file with OWS on Win and Mac the app runs but the same jnlp file does not run on Linux?

Can you please send the logs from the time it runs on Win and from the time it fails on Linux?

Please see https://openwebstart.com/docs/OWSGuide.html#_logging

Re: error generating xml files

OWS is starting your application but your application is crashing because it cannot find an class javax.activation.DataHandler. May be the JRE that was chosen to run the application does not have this class. Please send the openwebstart log files by enabling logging as described here: https://openwe...

Re: Building OWS from src

OWS 3.0.0-alpha2 is not complete. Features like Sandbox are missing. It does have an improved classloader. We gave it up for lack of resources. After all this is an opensource project and we have limited budgets.

Re: Building OWS from src

You can just take OWS-3.0.0-alpha2 and test the log4j issue. Let me know if it works out of the box.

We tried new class loader in OWS-3.0.0-alpha2 but it is not complete yet, it is missing the sandbox and some other features.
