findAll fails with missing expression, but ejb-ql looks OK
I am a somewhat experienced EJB programmer trying CMP for the first time. I have an existing app running smoothly with some BMP beans, so I think my configuration is OK. I took an existing BMP entity bean, converted it to CMP, and it deployed without error. I ran a simple test client which I have used before and got the attached error. Since the error message implies a faulty SQL query, I tried setting the log4j priority to TRACE but I got no additional information. I tried this with my default Oracle db and also with hsqldb; same results. There must be some simple error somewhere, but I don't see it. Source code for the EJB, client, and ant-generated ejb-jar.xml follow. Does anyone know what the problem is? Thank you very much.
I am using JBoss-3.0.4_Tomcat-4.1.12, Oracle 8.1.7, Win2K, Ant 1.5.1, Xdoclet 1.2b2.
