>Subject: upload fails in MultipartRequest for large files
>Date: Tue, 26 Mar 2002 15:10:03 -0500
>
>Hi folks. We're having problems uploading large files with the OReilly
>MultipartRequest class when using ssl. Files under 10mb work fine. If we
>upload more than that (in one large file or a combination of smaller ones),
>we get an Array Index Out of Bounds exception (dump follows). This only
>happens going through ssl; non-secure uploads work fine with very large
>files.
>
>I found a very similar bug report on the servlets.com site (description
>follows), and upgraded to the 19-Jun-2001 version of the
>com.oreilly.servlet package. Same symptoms after the upgrade.
>
>Any ideas or help would be most appreciated. Thanks.

>Environment:
>------------
>- Win2000 Server, patched up to latest levels
>- Tomcat 4.0.1 Binary distribution, running as a service
>- IIS 5.0, using ISAPI_Redirect.dll dated 12/08/01 (Thank you Henri Gomez!)
>- SSL Enabled through IIS
>- I have several servers with similar environments. Some servers have
>multiple logical web servers with multiple Tomcat instances. This
>particular server has only one instance of each. However, the same
>behavior
>is observed on any server/instance with SSL.
>
>Facts:
>------
>1] This only happens on https://, all other forms work fine.
>2] This only happens on files larger than just under 11MB (11,172,378
>bytes,
>plus or minus a few bytes for filename payload).
>3] The "Assert Failed" error comes from Ajp13.java, Ajp13Packet.java, or
>MsgAjp.java. I am not a Java programmer (yes, another one of those
>'systems' guys), but was able to dig throught the source to find the actual
>system.out lines.
>4] 11,172,378 / 1364 = 8191+-, the same size as the ajp packet. Why 1364
>ajp packets? Anything smaller works fine.

>Here's the bug report from servlets.com:
>
>
>
> Bug: File upload does not work with Apache JServ when uploading large
>binary files
>
>
> Symptoms: When handling a file upload the
>com.oreilly.servlet.MultipartRequest class throws an
> ArrayIndexOutOfBoundsException.
>
>
>
> Reason: JServ supports the older Servlet API 2.0 and in the API 2.0 source
>code for
> javax.servlet.ServletInputStream there's a bug in the readLine(byte[] buf,
>int off, int len) method
> where the len parameter is ignored, and as a result reading input lines
>that exceed the buf length
> will throw an ArrayIndexOutOfBoundsException.
>
>
>
> Workaround: The com.oreilly.servlet library has implemented its own
>buffering to work around this
> issue. If you're using another library, upgrade to a server that supports
>Servlet API 2.1 or later.
