Re: [rules-users] com.google.protobuf.InvalidProtocolBufferException thrown when deserializing

Hi Droolers, I am using DroolsObjectOutputStream/DroolsObjectInputStream to serialize/deserialzie a Stateful knowledgeSession. The process of serialziation worked well and the size of the file containing the serialzied infomation is about 150M. However, when I tried to deserialize the file into a session, I got an exception. The stacktrace of the exception is as follows: com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large. May be malicious. Use CodedInputStream.setSizeLimit() to increase the size limit. at com.google.protobuf.InvalidProtocolBufferException.sizeLimitExceeded(InvalidProtocolBufferException.java:89) at com.google.protobuf.CodedInputStream.refillBuffer(CodedInputStream.java:720) at com.google.protobuf.CodedInputStream.isAtEnd(CodedInputStream.java:666) at com.google.protobuf.CodedInputStream.readTag(CodedInputStream.java:99) at org.drools.marshalling.impl.ProtobufMessages$Header$Builder.mergeFrom(ProtobufMessages.java:963) at org.drools.marshalling.impl.ProtobufMessages$Header$Builder.mergeFrom(ProtobufMessages.java:769) at com.google.protobuf.AbstractMessageLite$Builder.mergeFrom(AbstractMessageLite.java:212) at com.google.protobuf.AbstractMessage$Builder.mergeFrom(AbstractMessage.java:746) at org.drools.marshalling.impl.ProtobufMessages$Header.parseFrom(ProtobufMessages.java:720) at org.drools.marshalling.impl.PersisterHelper.readFromStreamWithHeader(PersisterHelper.java:234) at org.drools.marshalling.impl.ProtobufInputMarshaller.loadAndParseSession(ProtobufInputMarshaller.java:221) at org.drools.marshalling.impl.ProtobufInputMarshaller.readSession(ProtobufInputMarshaller.java:152) at org.drools.marshalling.impl.ProtobufMarshaller.unmarshall(ProtobufMarshaller.java:117) at com.sample.engine.CepEngine.deserialize(CepEngine.java:308) at com.sample.engine.CepEngine.<init>(CepEngine.java:77) at com.sample.test.EventDataConsumer.<init>(EventDataConsumer.java:19) at com.sample.test.CepTimeTest.main(CepTimeTest.java:19) Exception in thread "main" java.lang.NullPointerException at com.sample.engine.CepEngine.initCommons(CepEngine.java:138) at com.sample.engine.CepEngine.<init>(CepEngine.java:90) at com.sample.test.EventDataConsumer.<init>(EventDataConsumer.java:19) at com.sample.test.CepTimeTest.main(CepTimeTest.java:19) It seems that some code of drools set the size limit of deserialized file. Thus, where can I set the size limit to meet my needs? Is there a configuration file I can use? Thank you very much. Any response will be appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/com-google-protobuf-InvalidProtocolBuff...
