Buying TeeChart Java ver. is under consideration.

But While we tested TeeChartJava2Evaluation(2009-04-27)_Example_Swing , there is an error.
Testing process:
1. Export Chart for .tej.
2. Import that file -> Error occurs.

So, I attach test files and a project source made in Eclipse.

Test Contents:
1) Success importing .xml files (TeeChart.xml)
chart1.setChart(chart1.getImport().getTemplate().fromXML("C:/TeeChart.xml")); ==> Success using .xml files
2) Fail importing .tej files (TeeChart.tej)
chart1.setChart(chart1.getImport().getTemplate().fromFile("C:/TeeChart.tej")); ==> Fail drawing Chart to import .xml files
Error message:

Code: Select all

Hi Seth,

With your application and your .jar file I've reproduced the java.lang.NullPointerException you mention.
Then I've tried with NetBeans and your .jar throws an java.io.InvalidClassException exception.
However, your .xml loads without problems both in Eclipse and NetBeans. With your .xml loaded in NetBeans, I've exported the chart to a new .jar file. This new .jar loads successfully in NetBeans but in Eclipse. Find it attached here. Could you please try it in your Eclipse?

Hi Yeray

I tested your sample file with getImport().getTemplate().fromFile() in Eclipse , but it had InvalidClassException, too.

Error Message:
java.io.InvalidClassException: com.steema.teechart.TeeBase; local class incompatible: stream classdesc serialVersionUID = 75565439472837495, local class serialVersionUID = -1669827993778815851

And, TeeChart.tej that I've sent you have been saved with [Show Export Dialog] offerd TeeChartJava2Evaluation(2009-04-27)_Example_SwingTeeChart.Features.jar of Exporting.

Pleas check again.

Hi Seth,

Thanks for the feedback. I've added it to the defect list to be fixed in future releases (TJ71015420).
