ClassNotFoundException java.awt.Window$Type java.net.URLClassLoader$1.run

My apologies if this is a newbie error but I'm not able to run clj-ns-browser from the repl as per the instructions. I'm running the stock Java 1.6 on Mac OS X 10.7.5.

Please let me know if you'd like more info. regards, Alex

Hi Alex,

No need to apologize (ever ;-) )

It seems you're running into an incompatibility issue between java 6 and 7, and I used java 7 to compile, while you're using java 6 to run…

Please take a look at the associated discussion-thread in the seesaw-clj google-group:

https://groups.google.com/forum/?fromgroups=#!topic/seesaw-clj/WlXFIxGpaAs

I'm afraid there is no quick easy answer…

What you could do is either upgrade to java 7 if you can.

Or build the clj-ns-browser from source yourself, and keep it in your local maven-cache ("lein compile, jar, install"), because the source itself is explicitly dependent on java 7 and is know to compile&run well on java 6.

Or wait till I figure out how to compile, build and maintain a version for java 6, as I only have a version 7 right now.

Sorry for the inconvenience and thanks for pointing out the incompatibility.

Regards, Frank.

Just noticed a confusing typo:

I wrote: … because the source itself is explicitly dependent on java 7 …

but I meant: … because the source itself is NOT explicitly dependent on java 7 …

-FS.

Would it not be possible to catch the exception, and dump a nicer error message? Or run a "on Java 6, it's going to crash" check?

I updated to Java 7 (hadn't realised my machine was on 6). But lots of people will just give up!
