TextDemo from the scratch / regarding the tutorial #137

Closed seteahconnoc closed 2 years ago

seteahconnoc commented 2 years ago

Hello

I was able to follow this instructive tutorial: https://docs.leaningtech.com/cheerpj/Tutorial.html The authors made use of this jar file: https://docs.oracle.com/javase/tutorialJWS/samples/uiswing/TextDemoProject/TextDemo.jar The corresponding java source is found here: https://docs.oracle.com/javase/tutorial/uiswing/examples/components/TextDemoProject/src/components/TextDemo.java

I tried to generate a TextDemo.jar by using TextDemo.java. I managed to execute the jar file on my system. Sadly, I wasn't able to use cheerpj on my jar file.

I am quite aware, that the task of cheerpj is to get jar files running in a browser - and not to generate generate good java code.

Anyway, it would be quite helpful, if someone could help me on generating a TextDemo example from the scratch (based on a java file). Obviously, I'm using something, that isn't supported by cheerpj. I guess that the documentation of a working example would be easier for the community than analyzing my error logs.

Thanks for cheerpj. Feel free to ask for further details. Any suggestions would be welcome.

CheerpJ supports only Java 8 at this time. You are building the code using Java 11.
