When I am writing some content to a XML file using FileWriter.But it giving java.lang.OutOfMemoryError .TheactPolicy.toXml() returns a String.Which contains huge data of 150 MB.How to write a big file Pls help.
filetoCreate = file_path_xml + getCalendarDate() + file_name;
FileWriterfw=new FileWriter(filetoCreate);
BufferedWriterbw =new BufferedWriter(fw);
bw.write(actPolicy.toXml());
bw.close();
fw.close();
Read and write a little at a time, rather than the entire thing at once. If this is not possible then increase your allocated memory for java (as long as you have enough physical memory) using the -Xms and -Xmx options.
Yurgh.
Refactor for that method to accept a stream so it can write its info to a file instead of storing it all in memory. Returning such a String is just pointless.
Yup, as the-non-programmer says
actPolicy.toFile(file_path_xml + getCalendarDate() + file_name)
http://www.exampledepot.com/egs/javax.xml.transform/WriteDom.html looks about right to me.
Cheers, Keith.
