Thread-topic: java.lang.OutOfMemoryError during downloads
Hi
if i am not wrong the streamlioning functionality in webobjects is to overcome the problem of uploading and downloading huge files right.Please correct me if I am worng.But now I am uploading a file (<filename>.tar.gz) of size 17.2 MB.The upload is happening prperly.But now if i downlod the file from the application server to the users desktop ,I am getting the following error
.
2003-11-22 11:19:59 IST] <WorkerThread0> <WOWorkerThread id=0 socket=null> Throwable occurred: java.lang.OutOfMemoryError
[2003-11-22 11:19:59 IST] <WorkerThread0> java.lang.OutOfMemoryError
<<no stack trace available>>
[2003-11-22 11:19:59 IST] <WorkerThread0> <WOWorkerThread id=10000 socket=null> Workerthread exiting due to error, respawning with ID 10000...
com.webobjects.foundation.NSForwardException for java.lang.OutOfMemoryError
<<no stack trace available>>
.I am not very sure of what this error is.But I think this error has occured because of low memory.But this should not happen because of streamlining functionality.Can you please tell me why this has occured.While downloading the file, i am actually sending it from the application server by appending it to the response object.Below is the code for the same.Please tell me if I am going wrong somewhere.
public void appendToResponse(WOResponse aResponse, WOContext aContext) {
aResponse.setHeader("application/octet-stream","content-type");
aResponse.setHeader("attachment;filename=\"" +
downloadFileName + "\"", "content-disposition");
try{
aResponse.appendContentData(data.dataWithContentsOfFile(filePath));
}catch(IOException ex){
ex.printStackTrace();
}
aResponse.setContent(data);
isdownloaded=false;
}
