Hi,
I am not able to set the license for aspose cells on web application, we have temporary license for non-commercial use only, below is the code which is used to set the license
License license = new License();
license.setLicense(INPUT_STREAM_OF_THE_LIC);
INPUT_STREAM_OF_THE_LIC is not null and it is initialized with the correct input-stream of the license file. When we set the license locally i.e. on standalone JVM it works fine, but we get below error when we deploy on web application.
Caused by: com.aspose.cells.CellsException: Cannot find black listed licenses resource or black list is invalid. Please report this error to Aspose.

When I debugged the byte code of the “com.aspose.cells.License” it seems that we have problem locating to the resource file named “Aspose.License.BlackList.xml”.
The same issue was reported for aspose powerpoint in the forum Cannot find black listed and it seems you guys have fixed the issue of the resource loading for the black list, but don’t know how it still getting the exception.
Could you please tell me if I need to do something else for the web application deployment or is it a issue. and the web application we are using is “jboss-4.2.1.GA” and soon well be migrating to “jboss-6.1.0.Final”.
thanks,

Hi,
Can you please try this?
Make some folder on some drive say: c:\myfolder
Place license file there and then modify your code like this
Note: Suppose your license file name is Aspose.Total.lic so the full path to your license will be c:\myfolder\Aspose.Total.lic
[Java]
string yourLicenseFilePath=“c:\myfolder\Aspose.Total.lic”;
License license = new License();
license.setLicense(yourLicenseFilePath);
Hi,
I made the changes told by you and I end up with the same exception. As a note I think its the resource loading issue (ClassLoader) for Aspose, where in the method “b” of License class, it tries to load the resource named “Aspose.License.BlackList.xml” and can’t find it, when we run locally i.e. from standalone JVM its not a problem, the exception comes only when we deploy our web application and we try to set the license as stream or as file name.

Hi,
We have tested a simple web application with jboss-6.1.0.Final and cannot find the issue. Our code looks like following:
License lic = new License();
lic.setLicense(“Aspose.Cells.lic”);
Workbook wb = new Workbook();
wb.save(“res.xls”);
