Exception loading Custom DataSource FieldsProvider

[levas]

I am using iReport 3.6.2 (embedded in Netbeans) and have a custom datasource that I am migrating from the old iReport 3.0.0 stand-alone style.

While migrating, among other changes, I changed the FieldsProvider from it.businesslogic.ireport.FieldsProvider to com.jaspersoft.ireport.designer.FieldsProvider.

Then I place my custom data source jar in some directory and set the iReport classpath to point to it.  For example I edit the ireport.properties file and create a line that looks like:

IREPORT_CLASSPATH=;C\:\\Downloads\\JasperSoft\\iReport\\3.6.2\\iReport-3.6.2-src\\build\\testuserdir\\lib\\MyCustomDataSource.jar;C\:\\Downloads\\JasperSoft\\iReport\\3.6.2\\iReport-3.6.2-src\\build\\cluster\\modules\\ext\\jasperreports-extensions-3.5.3.jar

When I run iReport I see the classpath set in the options. 

I also set up a query executor for my custom datasource, setting the language name, the executor factory class name and the fields provider class name. I am positive that the class names I set are correct.

So when I create a report, edit the query, and set the language to my custom data source's language, a ClassNotFoundException is thrown.  The exeption from the log file is included.

I walked through the source and found that my when the class is being loaded by the class loader the excption is being thrown. This is around line 1276 in ReportQueryDialog.java.  I assume is a classpath problem.

any help on this would be appreciated.

Thanks,

Rob
