Too many open files - A p:graphicImage Error (I guess)

[Vandre Caetano]

Hi there

I an jsf application the user upload photos and I am using primefaces <p:graphicImage> tag to show the photos and <p:fileUpload> to upload then, but when put this code in the production server, it start to get really slow and throws a "too many open files" Error

Do you have any idea what could be possibly wrong?

my code for uploading :

public void handleFileUploadImage(FileUploadEvent event) {
	UploadedFile file = event.getFile();
	String name = id + "_intern_" + getDataType(file.getFileName());
	upload(file, name);
}

public boolean upload(UploadedFile uploadedFile, String name) {
	try (InputStream stream = uploadedFile.getInputstream();
	     FileOutputStream outstream = new FileOutputStream(IMAGE_SOURCE + "/" + name)){
	    
	    long size = uploadedFile.getSize();
	    byte[] buffer = new byte[(int) size];
	    stream.read(buffer, 0, (int) size);
	    outstream.write(buffer);
	    return true;
	} catch (Exception ioe) {
	    return false;
	}
}

And to read the image:

public DefaultStreamedContent getImage(String name) {
	try {
	    return new FileInputStream(IMAGE_SOURCE + "/" + name);
	} catch (FileNotFoundException e) {
	    return null;
	}
}

Of course I found no way to close this fileInputStream so far but I sow its implementation of finalize and it seems the garbage collector should be able to handle it... I guess


Do any of you know who to fix it?

By the way, I'm using glassfish 3.1.2 and the homologation server often behaves differently than the glassfish in my computer.

Thanks in advance
