Hi Andy Taylor I downloaded the messging (jboss-messaging-1.3.0.GA-src) source code and modified some lines. I followed these steps, 1. opened the org.jboss.messaging.core.plugin.JDBCPersistenceManager.java. 2. Modified the code at line no :2716 and 2760. 3.changes are: i) // ps.setBinaryStream(columnIndex, is, bytes.length); to ps.setBlob(columnIndex, (Blob)is); ii) //InputStream i = rs.getBinaryStream(columnIndex); to InputStream i = (InputStream) rs.getBlob(columnIndex); Now perfectly working. Is this the right way?. if ok , Is there any changes are Still required ?. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123532#...
