I have a problem to launch the application on mac os x 10.6.8.

Hi, Nicolas. What version of the Java Runtime Environment (JRE) are you running? If it's not the most current, please update your JRE and let me know if that fixes it. Thanks.
Hi,
I looked for the latest version of JRE on the Apple website:
http://support.apple.com/kb/dl1573.
Thank you for the support.
PS: is that it is a 64-bit version?

#3Well, Nicolas, you didn't tell me what JRE version you have installed. Your link to http://support.apple.com/kb/dl1573 does not work.
I did search the Apple support site and it appears that OS X with patches would be running Java 6 at best. The pre-compiled LDCT JAR file requires Java 7 and the error messages suggest that this is the problem. No, the 64-bit thing should not be an issue given how Java works.
It seems that you have two options:
You can install an OS X version of Java 7 from http://java.com/en/download/faq/java_mac.xml#getjava.
You can download the LDCT source code and recompile for your environment.
I hope the above will solve the problem for you. Please update this discussion/ticket if you have more information. I'll leave this ticket open for a few days in case that happens.
Thanks,
robert
Hi,
I checked I have the latest version of JAVA.
The link you provide me (http://java.com/en/download/faq/java_mac.xml
getjava #) does not work with Snow Leopard.
Link told me to go through the update software (in the Apple menu if you
know).
So I do not have a choice I have to be recompiled JAVA application from
source code in console mode?
I leave you to manage the trouble ticket.
Thank you and best regards.

#3Hi,
Thank you it's me who is not understood as it should.
Excuse my English level.
I'll try with the source code compiled on my platform.
Can you give me the command line, I am no longer JAVA development for a
while.
Thank you and best regards.

#3Well, I attempted to compile for Java 6. There were 83 errors so it won't be a simple recompile. Give me a few days to see if I can make the changes.
Nicolas, I have modified the source code for Java6 and compiled a new JAR file. Go to the Files tab and go into the Temp folder. Download "LDCT v0.9.17 Java6.jar" and see if this works for you.
Please do not include all of the previous discussion text in your reply. Thanks.
One more thing, Nicolas: There seem to be lots of "how to install Java 7 on snow leopard" answers out there. Here's one:
http://geekforgeek.com/archives/java-update-to-version-7-on-mac-os-x-snow-leopard
You might want to do some searches and give it a try.
The Java6 version worked so I'm closing this ticket. I'll open a new ticket regarding the internationalization issue.
Note that I may or may not support Java6 going forward. Thanks.
