Play 2.0框架中允许的表的最大数量是多少？

Question

嗨所以我创建了一个快速的表：

package models; 
import javax.persistence.*; 
import play.db.ebean.Model; 

@Entity 
public class Phone extends Model { 
@Id 
public Long phoneID; 
public String group; 
public String name; 
} 

，我也得到了以下错误：

PersistenceException: Error getting sequence nextval javax.persistence.PersistenceException: Error getting sequence nextval com.avaje.ebean.config.dbplatform.SequenceIdGenerator.getMoreIds(SequenceIdGenerator.java:213) com.avaje.ebean.config.dbplatform.SequenceIdGenerator.loadMoreIds(SequenceIdGenerator.java:163) com.avaje.ebean.config.dbplatform.SequenceIdGenerator.nextId(SequenceIdGenerator.java:118) com.avaje.ebeaninternal.server.deploy.BeanDescriptor.nextId(BeanDescriptor.java:1218) com.avaje.ebeaninternal.server.persist.DefaultPersister.setIdGenValue(DefaultPersister.java:1304) com.avaje.ebeaninternal.server.persist.DefaultPersister.insert(DefaultPersister.java:403) com.avaje.ebeaninternal.server.persist.DefaultPersister.saveEnhanced(DefaultPersister.java:345) com.avaje.ebeaninternal.server.persist.DefaultPersister.saveRecurse(DefaultPersister.java:315) com.avaje.ebeaninternal.server.persist.DefaultPersister.save(DefaultPersister.java:282) com.avaje.ebeaninternal.server.core.DefaultServer.save(DefaultServer.java:1577) com.avaje.ebeaninternal.server.core.DefaultServer.save(DefaultServer.java:1567) com.avaje.ebean.Ebean.save(Ebean.java:538) play.db.ebean.Model.save(Model.java:76) models.Command.createCommand(Command.java:100) models.Command.populateCommands(Command.java:68) Global.onStart(Global.java:22) play.core.j.JavaGlobalSettingsAdapter.onStart(JavaGlobalSettingsAdapter.scala:15) play.api.GlobalPlugin.onStart(Global.scala:134) play.api.Play$$anonfun$start$1.apply(Play.scala:60) play.api.Play$$anonfun$start$1.apply(Play.scala:60) scala.collection.LinearSeqOptimized$class.foreach(LinearSeqOptimized.scala:59) scala.collection.immutable.List.foreach(List.scala:45) play.api.Play$.start(Play.scala:60) play.core.ReloadableApplication$$anonfun$get$1$$anonfun$apply$3$$anonfun$1.apply(ApplicationProvider.scala:125) play.core.ReloadableApplication$$anonfun$get$1$$anonfun$apply$3$$anonfun$1.apply(ApplicationProvider.scala:112) scala.Option.map(Option.scala:133) play.core.ReloadableApplication$$anonfun$get$1$$anonfun$apply$3.apply(ApplicationProvider.scala:112) play.core.ReloadableApplication$$anonfun$get$1$$anonfun$apply$3.apply(ApplicationProvider.scala:110) scala.Either$RightProjection.flatMap(Either.scala:277) play.core.ReloadableApplication$$anonfun$get$1.apply(ApplicationProvider.scala:110) play.core.ReloadableApplication$$anonfun$get$1.apply(ApplicationProvider.scala:110) akka.dispatch.Future$$anon$3.liftedTree1$1(Future.scala:195) akka.dispatch.Future$$anon$3.run(Future.scala:194) akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:83) akka.jsr166y.ForkJoinTask$AdaptedRunnableAction.exec(ForkJoinTask.java:1381) akka.jsr166y.ForkJoinTask.doExec(ForkJoinTask.java:259) akka.jsr166y.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:974) akka.jsr166y.ForkJoinPool.runWorker(ForkJoinPool.java:1478) akka.jsr166y.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:104)

有表，我的最大数量使用H2内存数据库允许吗？我真的不明白这个错误来自哪里。如果我删除此行能正常工作，但它看起来像另一个类引起的问题：createCommand，刚刚有以下几点：

public static void create(Command data) { 
    data.save(); 
} 
public static void populateCommands() { 
    createCommand(0x00, "Cmd1"); 
    createCommand(0x02, "Cmd2"); 
    createCommand(0x03, "Cmd3"); 
} 

任何帮助表示赞赏。

我认为问题在于我打开了eclipse。 我已经注意到一些与eclipse有关的问题，并在同一时间运行。 我需要关闭eclipse，再次运行播放框架和open eclipse。
