I have an application which stores PDF documents in a longblob column of a
MySQL 5 table. A standalone Java application writes to the table and persists
the documents to the table. The documents can be downloaded via a web
application. The code to retrieve the documents is straight forward:
...
rs = stmt.executeQuery();
if (rs.next()) {
Blob blob = rs.getBlob(1);
InputStream in = blob.getBinaryStream();
}
The code works in Tomcat 5 but in JBoss 4.0.2 the call to rs.getBlob(1) throws
the following exception:
java.lang.reflect.UndeclaredThrowableException
at $Proxy77.getBlob(Unknown Source)
Caused by: java.lang.IllegalAccessException: Method=public abstract
java.sql.Blob java.sql.ResultSet.getBlob(int) throws java.sql.SQLException does
not return Serializable
...
..
Replacing rs.getBlob(1) with rs.getBinaryStream(1) also throws the same
exception.
This problem and a few other JDBC related problems are beginning to raise a lot
of doubts in my head about JBoss. The application works on Geronimo and Tomcat,
but I hate Geronimo and Tomcat has no EJB container. Help!
