bad version number in .class file

[andries]

I am trying to implement the Aspirin framework to send SMTP messages.

However I always get the bas version number in .class file error. Apparently this means that I am running an older version of Java then in which the Aspirin.jar file is compiled. This actually surprises me as my current Java version is really up to date ( I am working on Mac OS X ).

I have following Java Environment installed: J2SE 5.0

Does anyone have a clue? or got already into this problem?

Can you post the exact error message that you're getting? This will help figure out what version of Java it's looking for.

[andries]

of course :

this is the code I am trying to run

import java.io.IOException;  

import java.util.Properties;  

import java.lang.*;

   

import javax.mail.Message;  

import javax.mail.MessagingException;  

import javax.mail.Session;  

import javax.mail.internet.InternetAddress;  

import javax.mail.internet.MimeMessage;  



import org.masukomi.aspirin.core.*;



MimeMessage msg = new SimpleMimeMessageGenerator();



return "test"

this is the error ScriptMaster returns:

I'm getting similar errors - the plugin won't even run in filemaker 10 adv on 10.5.7 server

with the latest scriptmaster 3.301

and it's not the nice new design that I see in the video!!

some log entries:

[Jesse Barnum]

Can you try download the newest version (posted just minutes ago at 10:47 am) and see if that fixes the problem? There was a problem with our initial build of 3.301 where it required Java 6, we've posted a new build and kept the 3.301 version number.

[andries]

I installed the new version.

the error remains the same, but I get now two dialog boxes. First the one that was always there showing you the error "Looks like an error occured".

Next I get a dialog box: "360Works ScriptMaster Error" with the message: java.lang.UnsupportedClassVersionError: Bad Version number in .class file

[Smef]

Could you please send me your log file immediately after you get this error next? Logs can be found at:

thanks in advance !

[holstermedia]

Great - it works ok for me now:

fmp adv 10

thanks!

[Jesse Barnum]

Andries, thanks for sending the log file. Your computer is set to load Java 1.5 by default:

jvm version: 1.5.0_22-147 from /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home

It looks like the Aspirin framework is set to require Java 6. That is why you're getting this error; Java 5 cannot run classes compiled in Java 6. Your best solution would be to either:

1) Get a version of the Aspirin framework compiled for Java 5

2) Upgrade to Snow Leopard, which makes Java 6 the default.

[andries]

allright I will give this a try.

Can you explain me how you see this? I really tried reading the error log, but couldn't find it.

thanks !

[andries]

works perfect !

if I get something working, I'll come back with it!
