hibernate annotations compile error

Question

I'm encountering a strange problem when i try to compile a DTO file which has hibernate annotations to map to db . when fails with a strange message log below. what could be the cause of this problem? i suppose the error comes from file CashDTO . what am i doing wrong in file CashDTO.java?

Solution

Sounds like the classes for javax.persistence are not on the classpath of the javac task in your test-ws Ant target.

This is caused by the bug in compiler - bugs.java.com/view_bug.do?bug_id=6550655

hmm strange! before i added class CashDTO the test-ws was running successfully and CashDTO is not different from other old DTOs in my code. why only class CashDTO that complains about it and not other DTO classes very similar to CashDTO?

[othman]

sorry you right. i shouldn't use hibernate annotated DTOs in my test-ws . i have to create another DTO to use with test-ws.

[rogerdpack]

But why doesn't javac have them by default in its classpath, that's my question? javac itself is nestled within the JDK c:\Program Files (x86)\Java\jdk1.6.0_26\bin\javac.exe so shouldn't it find them?

@rogerdpack, I don't think the JPA libraries ship with the JDK, unless that is a recent change.

[rogerdpack]

That makes sense. For some reason I thought they did but I guess they only do with Netbeans/J2EE or something like that. So my next question is whether getting them from hibernate is the best place or not...it's surprising that something that's javax.xxx doesn't ship with the JDK tho...
