Currently we are using Aspose 220.127.116.11 jar for JDK 1.4
When we faced an issue (File error:data may have been lost) two days ago, Aspose team asked us to replace the Aspose Jar 18.104.22.168 with the latest version 7.0.1 to resolve the issue.
We found out that the above issue occurs when the report created and saved in Microsoft Office 2003 are opened in Microsoft Office 2010.
When we downloaded the latest version (Aspose 7.0.1) from the Aspose site and replaced our Jar with latest Jar ,we came across many compile time errors.
Some of the Classes like BorderLineType,NamedRange,HorizontalAlignmentType,CellHandler,LightCell,Worksheets which we make use of during excel rendering are not even found in the latest Aspose Jar. We are not sure if any new API does this job for us.
Ex: BorderLineType and NamedRange classes are found in com.aspose.cells package in the previous versions.But these classes are not found in the same package.
To use the new Asopse Jar, huge amount of code changes will be required in our application which is not the feasible solution. Ideally, when a new version is introduced, it should have backward compatibility. But looks like the new Aspose Jar is not backward compatable.
Please let know if there is a feasible way of handling the above scenario where the existing functionalities are not broken.
