The server is Web sphere 6.0 the JVM is 1.4 thus I would assume 32 bit.

It is a heap size limit then???

I don't recall the specific array size limitations of 32 and 64 bit JVMs, but I seem to recall reading that the limit is much higher for 64 bit JVMs. Which JVM are you using?

Subject: [WEB400] SOAP Webservice returning PDF document

I have a requirement to return a PDF document on a call to the web service. It works beautifully, to a point, and was a lot of fun to code. 95% of the PDFs will be under 1M in size, but there will be a few that are greater than 16M, I have a test that is 26M. This is the point where the web service fails, and I'm not sure where to go from here, if there is any where to go.

The error message is "CPIAD07 - Host server error occurred with reason code 10 - 10 -- Reallocation of server buffer failed." This occurs in the web service Java code where it allocates the storage for the PDF "byte[] artifactInputBuf2 = new byte[artifactSize];" where artifactSize is the size of the PDF file on the server.

I'm not sure if this is a *SNGLVL/*TERASPACE issue or the Java program's heap space size, but is there any way for Java to "allocate" a byte array larger than 16M?
