How to avoid OutOfMemoryError when uploading a large file using Jersey client

Question

I am using Jersey client for http-based request. It works well if the file is small but run into error when I post a file with size of 700M:

Exception in thr         


        

Answer 1

If possible, can you split the file you send into smaller parts? This will reduce memory usage, but you need to change the code on both sides of the uploading/downloading code.

If you can't, then your heap space is too low, try increasing it with this JVM parameter. In your application server add/change the Xmx JVM options. For example

-Xmx1024m

to set Max Heap Space to 1Gb
