how to debug why the jar main class is not loading

I am trying to convert old jnlp client to html format. I followed the documentation and used cheerpjRunMain. But still i am getting could not find or load main class. I am sure i have added the jar under app/.

Can you please share how is being called? Also please check the network tab to make sure the JAR is actually requested via HTTP

No jar is not being requested

apignotti•10/30/23, 5:53 PM

Then most likely the classpath used in is not correct. Can you share that line?

I think a similar issue happened to another user before, but I've just checked the docs and they look correct to me. Could you help us understand how we could have made the docs more clear?

Thats my mistake. I think i created app and thought it would be redirected there. Is there a way to add wildcards for the libraries

No, you need to list the jars explicitly. We are currently working on a Chrome extension to run JNLPs automatically. Consider getting in touch at sales@leaningtech.com for a preview if this is for a commercial project.

Also, by mindful that represents the root of the HTTP server. If the main class still cannot be loaded use the network tab to debug what URL is being loaded.

Great thank you

One more question is to how to inject jnlp property and extensions

Mukesh NairOP•10/30/23, 6:11 PM

I am interested in knowing more about chrome extension i will try contacting sales

apignotti•10/30/23, 6:14 PM

About properties, you simple add them to the call as documented here: https://labs.leaningtech.com/cheerpj2/reference/Runtime-API#javaproperties

apignotti•10/30/23, 6:14 PM

I am not sure what you mean by jnlp extensions, can you clarify?

Mukesh NairOP•10/30/23, 6:18 PM

Mukesh NairOP•10/30/23, 6:18 PM

Its part of jnlp syntax

apignotti•10/30/23, 6:19 PM

Please understand that I am not a JNLP expert myself, but it seems to me that it just another JNLP file that needs to be expanded and included in the / command.

Mukesh NairOP•10/30/23, 6:38 PM

Sure will try out. Thanks a lot @ap87no
