Unmarshalling Error Java Heap Space

Contents

Is there any other more 'memory efficient' method of parsing large XML files ~ 500mb? The object I am marshaling has a byte array property. Because of this i am getting outofmemory error. If you expect how to quickly fix the problem, then the answear would be expanding JVM memory. navigate here

Jaxb Unmarshal Large Xml Files

Here is the marshaling I am doing: StringWriter writer = new StringWriter(); jaxbContext = JAXBContext.newInstance("package name"); Marshaller jaxbMarshaller = jaxbContext.createMarshaller(); jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,Boolean.TRUE); jaxbMarshaller.marshal(myObject, writer); return writer.toString(); the error I am Automated exception search integrated into your IDE Test Samebug Integration for IntelliJ IDEA 0 mark UnmarshalException when getting informations from my server using SOAP Stack Overflow | 2 years ago | The only significant amount of memory a map task would need would be for loading in libraries needed for execution. share|improve this answer answered Oct 12 '15 at 6:24 Prem 995 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign

  1. There are a few additional issues to be aware of when managing task attempt memory.
  2. What does 彼女は私ほど自分のことを好きじゃない mean?
  3. Any help is appreciated.
  4. Does DFT produces the same output as FFT?
  5. Calculate memory needed.

Why don't miners get boiled to death at 4 km deep? So if you increase the amount of memory given to each task attempt JVM, you will also need to reduce the number of map/reduce task slots presented by TaskTrackers. How do we play with irregular attendance? What does 彼女は私ほど自分のことを好きじゃない mean?

Strange device identification Is Certificate validation done completely local? JAXB will then advance the XMLStreamReader to the end of that element. Before I leave my company, should I delete software I wrote during my free time? Not the answer you're looking for?

This is a complex situation, because if you run different jobs concurrently on a cluster, you can have task attempts from one job (job A) that need lots of memory, and Browse other questions tagged java web-services soap jax-ws cxf or ask your own question. If you know how much memory your map task attempts should receive (in this case it’s 512MB), the next step is to launch the JVMs with that amount of memory. asked 5 years ago viewed 7754 times active 1 year ago Get the weekly newsletter!

up vote 1 down vote favorite 1 Currently I am using JAXB marshaller to marshall the lasrge java object and it is working but when i recive the large java object It is very strong tool and is able to use SAXt at least for parsing, so probably it knows to serialize objects incrementally too. Then we look for the next fragment we want to unmarshal from. –Blaise Doughan Nov 1 '11 at 19:03 1 @Tyc - You'll need to play with advancing the XMLStreamReader

Which towel will dry faster?

The problem was that i used SOAP instead of HTTP. The number of map/reduce task attempt slots presented by a TaskTracker is set at the time the TaskTracker starts, and is controlled via two settings in mapred-site.xml on each node: mapred.tasktracker.map.tasks.maximum How can I make two cutting lines close to each other? it works now.

Limit your nodes use of swap space and paged memory. Are you running an application or a web app? –Tim Biegeleisen Oct 12 '15 at 5:38 @Tim Biegeleisen can you tell me how to check current heap and memory The first step in avoiding Java heap space errors is to understand memory requirements for your map and reduce tasks, so that you can start the JVM with an appropriate memory weblink I keep getting java.lang.OutOfMemoryError: Java heap space @ Unmarshaller um = JAXBContext.newInstance("com.sample.xml"); Export e = (Export)um.unmarhsal(new File("SAMPLE.XML")); I'm guessing this is becuase it's trying to open the large XML file as

thanks a lot. I am not sure, but try XStream. If possible, how to include cut marks in PDF? (using watermark?) What are the German equivalents of “First World War”, “World War I”, and “WWI”? Probably XML representation occupies twice more.

If you want to write XML to file use FileWriter directly. Remember that there are default settings that come into play when launching those JVMs, unless you have explicitly overridden them. What do you call someone without a nationality? Do pulled hair from the root grow back?

It's true that you could combine StaX and JaxB to selectively parse XML fragments, but it's not always possible or preferable.
