Connection to partner broken error message

[Former Member]

Hi everyone,

We have an issue with uploading of large files on NetWeaver 7.1 SP3 (it works fine for small files). After some time of upload running, the following exception is thrown:

....................................................

Caused by: org.jvnet.mimepull.MIMEParsingException: com.sap.bc.proj.jstartup.fca.FCAException: Cannot get InBuffer: -7 connection to partner broken.

Is it possible to tune the http service like in NW 6.4 version?

Thanks,

Hi Shaji,

we have two possibilities to upload large files:

1. Using MTOM Web Services. Here we provided our own Web Services implementation layer based on JAX-WS 2.1.3 reference implementation. For larger files we got the “connection broken” exception, with the following NW related stack trace:

…………………….

……………………….

2. Using the HttpServletRequest input stream. In this case, the NW related stack trace is:

……………………………..

Again, it works well for small files.

Thanks in advance,

The solution to our problem was to update NW from SP3 to SP5 and to install all patches released after SP5 !
