Thanks for the helpful hints.
In addition to your hint, I also found the following in another discussion answer from PTC-167919.
ant -f bin/tools.xml class -Dclass.includes=*.java -Dclass.source=C:\LoadECR
I used this syntax using my folder structure to complete the compile.
My Java and class skills are not good. As I was looking at the examples in the Customizer guide, I found references to fields like 'Default_Representation' in DerivedImage. Since I was looking to use the DerivedImage table and the field Last Modified field, I was expecting to use the syntax 'Last_Modified' but keep getting 'cannot find symbol' in reference to using 'Last_Modified' during the compile.
I can't believe how difficult it seems to be to find references to the field names for use in the queryspecs. I obviously am still missing where to find this info. In the report management tool, Last Modified field is in the DerivedImage table.
*** Last_Modified as a date field - I did see reference to ModifyStampA2 ***
SearchCondition sc2 =
new SearchCondition(DerivedImage.class,
DerivedImage.Last_Modified,
SearchCondition.LESS_THAN, DateExpression.newExpression("2012-01-01"),
0L);
There must be some other documentation that is worth reading that I haven't come across.
Thanks,
Mike
