thinkorswim Java app for equities trading...

[Dariusz Piatkowski]

Has anyone had any luck getting this to work in OS/2?

I have the following version of JRE installed:

java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-b05)
Java HotSpot(TM) Client VM (build 1.4.2_09-b05, mixed mode)

Here is the link to the software download page:

And here is the direct link to the 'non-windows/linux' platform Java installer:

Attempting to get this running I get the following:

[G:\TEST\THINKORSWIM]\java142\bin\java -jar launcher.jar
java.lang.NoClassDefFoundError: java/io/Closeable
at java.lang.Class.getDeclaredMethods0(Native Method)

at java.lang.Thread.run(Thread.java:534)

I thought I'd try the 'work-around'...which is to install the WIN version, and
then get the JAVA application over to my OS/2 machine, this was a good plan, but
I ran into the "major.minor" Java problem...and there just isn't much I can do
about that, see the following:

[G:\TEST\thinkorswim_win]\java142\bin\java -verbose -jar launcher.jar > output
