    copied!<p>I am trying to migrate my Spring project from Hibernate to ObjectDB. On ObjectDB page, they say that ObjectDB is 100% compatible with JPA. However, I have problem with this JPQL query:</p> <pre><code>SELECT e FROM Employee e WHERE e.present = false AND NOT EXISTS (SELECT c FROM Computer c WHERE c.employeeEntity = e) ORDER BY e.name </code></pre> <p>with Hibernate, there was no problem with this query, but ObjectDB throws exception:</p> <pre><code>com.objectdb.o.UserException: Unexpected query token 'EXISTS' </code></pre> <p>Second problem is with Criteria Language. This code:</p> <pre><code>In&lt;Employee&gt; inExpression = cb.in(root.get(Computer_.employeeEntity)); for (Long id : emplIds) { Employee e = new Employee(id); inExpression = inExpression.value(e); } list.add(inExpression); </code></pre> <p>was working with Hibernate, with ObjectDB it is throwing:</p> <pre><code>com.objectdb.o.UserException: Unexpected query token ':l2' at com.objectdb.o.MSG.d(MSG.java:61) at com.objectdb.o.TKN.J(TKN.java:765) at com.objectdb.o.QNF.B(QNF.java:894) at com.objectdb.o.QNF.I(QNF.java:1294) at com.objectdb.o.QNF.k(QNF.java:315) at com.objectdb.o.QNF.H(QNF.java:1270) at com.objectdb.o.QNF.k(QNF.java:210) at com.objectdb.o.QNF.t(QNF.java:611) at com.objectdb.o.QNF.t(QNF.java:605) at com.objectdb.o.QNF.k(QNF.java:218) at com.objectdb.o.QNF.j(QNF.java:135) at com.objectdb.o.QRC.z(QRC.java:321) at com.objectdb.o.QRC.v(QRC.java:212) at com.objectdb.o.QRC.u(QRC.java:166) at com.objectdb.o.QRM.U6(QRM.java:250) at com.objectdb.o.MST.U6(MST.java:933) at com.objectdb.o.WRA.U6(WRA.java:291) at com.objectdb.o.WSM.U6(WSM.java:113) at com.objectdb.o.STC.r(STC.java:449) at com.objectdb.o.SHN.aj(SHN.java:489) at com.objectdb.o.SHN.K(SHN.java:156) at com.objectdb.o.HND.run(HND.java:132) at java.lang.Thread.run(Unknown Source) </code></pre> <p>Does anybody have any idea how to solve these problems?</p> <p>Milan</p>
