Hi.

I'm using XADisk in my EJB for writing large files (> 20MB) to disk uploaded from my web application.

java.lang.ArrayIndexOutOfBoundsException is thrown with line "at org.xadisk.filesystem.virtual.NativeXAFileOutputStream.write(NativeXAFileOutputStream.java:91" repeated 1000x or more when using write(byte[]) method on XAFileOutputStream class.

This is my EJB method simulating that write operation using 50MB byte array:

public void testXADisk() {

byte[] b = new byte[50000000];

File file = new File("d:/temp/XADiskTest.txt");

try {

XADiskConnection c = this.xaDiskCf.getConnection();

c.createFile(file, false);

XAFileOutputStream xafos = c.createXAFileOutputStream(file, true);

xafos.write(b);

xafos.close();

} catch (Exception e) {

throw new RuntimeException(e);

} // end try-catch

}

... and the trace:

javax.ejb.EJBException: See nested exception; nested exception is: java.lang.RuntimeException: java.lang.ArrayIndexOutOfBoundsException

I'm using IBM Websphere Application Server 8.0.0.9 with installed XAFileSystem Resource Adapter 1.2.2.

Any ideas?

Thanks,

Igor

Hi Igor,

Please apply the following change to the file "NativeXAFileOutputStream.java", and see if it works for you:
https://java.net/projects/xadisk/sources/svn/revision/561 (click "diff")

This change is after 1.2.2, and is not in a release version yet.
Let me know if you have any questions.

Thanks,
Nitin
