About Teechart 2012 requirements

[Softwell]

Hello there,

I'm currently have the Teechart v1.
I would like to know somethings:

I used the trial, and realize that it requires the JDK 1.6 to be used (At least in the trial was like that).
1) I would like to know if it's possible to use the new version of teechart 2012 with JDK 1.5 (My project currently works on JDK 5).

2) I would like to know if the price to buy the 2012 version is the same as a new user or i have an "update price" ?

Waiting for answers.

Another question:

I've download my latest version available for v1:

Code: Select all

TeeChart v1 for Java with 100% Source Code
TeeChartJava_with_Sources.zip
February 02, 2010	
File size - 10,37 MB 

When i use the JDK 1.5 to "install" it (generate the TeeChart.Swing.jar) it give me the error:

Code: Select all

Well, the latest version of Teechart v1 isn't compatible with JDK 1.5 ?
I installed it using the JDK 6 and it extracted the TeeChart.Swing.jar sucessfully.
But when i run the jar in my application, i get the error:

Code: Select all

java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class com.steema.teechart.exports.ImageExport) at 

Well, i had a version of TeeChar.Swing.jar that currently works in my JDK 1.5 application, but i don't know how the old developer (doesn't work in my company anymore) get it working on JDK 5.

Waiting for answers...

Ok: About the question of JDK 1.6, i could generate the jar with 1.5 just getting the source and compiling it with JDK 1.5.

What about the others ?

Hi,

used the trial, and realize that it requires the JDK 1.6 to be used (At least in the trial was like that).
1) I would like to know if it's possible to use the new version of teechart 2012 with JDK 1.5 (My project currently works on JDK 5).

We are aware of this and trying to fix it.
I hope we can provide the next maintenance release built with 1.5.

2) I would like to know if the price to buy the 2012 version is the same as a new user or i have an "update price" ?

Find the prices for the upgrades and new licenses in the order page:

If you have any further question about prices, I'd suggest you to directly contact the sales department writing at "sales at steema dot com".

Ok: About the question of JDK 1.6, i could generate the jar with 1.5 just getting the source and compiling it with JDK 1.5.

The message above is confusing me. I'm not sure if you solved the problems with both v1 and the actual evaluation version, or just in one of them?

[Softwell]

Well,

I got the latest version of the v1 in the website and it is compiled using JDK 1.6.
But, i have the source code, so, i generated the jar with the SDK 1.5 and everything worked fine.

Then, i asked: The v3 is the same? Because the trial is compiled with JDK 1.6 too, but i don't have the source code of it (because i don't have v3 version) to know if i can compile with JDK 1.5 too...

Got it ?

Hi,

Right. The latest version (both the eval and the registered versions) were compiled with jdk 1.6. We are correcting it for the next maintenance release as we aim to support jdk 1.5.
In the meanwhile, we could provide a temporal evaluation version to those customers who ask for it. I'll send it to the mail account you have registered in this forum.
