Question

Getting java.io.EOFException while sending a large java object using AciveMQ.

Below is the large object that I am trying to send

class TestDataBean implements Serializable
{
private String testName = "TestName";
private String testDesc = "testDesc";

private String bigData = getBigString();

@Override
public String toString() {
    return testName +" : "+testDesc+" : "+bigData.length();
}


private static String getBigString() 
{
    StringBuffer stringBuffer = new StringBuffer();

    for(int i=0;i<1000; i++)
    {
        stringBuffer.append("tsssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss");
    }

    return stringBuffer.toString();
}

}

Below is the stackTrace.

Producer showing that its sending a proper object. But on consumer side it throws above exception.

I have also tried below configurations with ActiveMQConnectionFactory

ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(url);
        factory.setProducerWindowSize(1024000000);
        factory.setSendTimeout(600000);

Please suggest me some solution.
Thanks in advance.

Sorry, this was my mistake. Let me explain u what I was doing. – I was sending the message as StreamMessage – And reading this one in a byte array The size of data I was sending was about 70K bytes and As a SILLY MISTAKE the array I had was jus 10K capacity. n so I was getting this EOFException. Sorry I take ur time. And posting this hoping that no one else would be doing similar mistake 🙂 Thanks.
