I got a problem here.
We got a java application.
We store the pdf file as a blob in an Oracle database.
When we read it we have to write it out and then:
String command = "cmd /c start " + pathToPdfFile;
			Runtime.getRuntime().exec(command);

I was wondering if it is possible to avoid the write. We will not have write permissions any more.
Maybe somehow get
AcroRd32.exe to read it from a string, or to pipe it or something like that.

I was trying:

String command = " C:\\Program Files\\Adobe\\Reader\\AcroRd32.exe <" + blobString; or String command = " C:\\Program Files\\Adobe\\Reader\\AcroRd32.exe <" + "echo \"" + blobString + "\"";

Runtime.getRuntime().exec(command);

Does not work!!!
Does someone know???

Thanks!

PS. Running Java (J2SE) on Windows XP. Which I do not think makes any difference.
