Description: java.sql.SQLException: Invalid value for getInt() - 'attachments.zipapplication/zip$PK' at com.mysql.jdbc.ResultSet.getInt(ResultSet.java:1217) at com.mysql.jdbc.ResultSet.getInt(ResultSet.java:1233) at org.apache.commons.dbcp.DelegatingResultSet.getInt(DelegatingResultSet.java:220) at com.privasphere.privalope.db.MySqlSystem.getAttachment(MySqlSystem.java:3715) Admitted, we are testing the boundaries. After the usual iteration until in my.cnf set-variable = max_allowed_packet=70M we got 45 MB into the DB quite nicely (at least the overall size of the table file indicates that it worked.) But when retrieving with the below query, we get this error. With about 13.6 MB - all works fine! The DBMS appears to be 4.0.13 on linux. First I thought this may be a AES decryption problem, but at least the error text is intelligible (the content have the filename "application.zip"). Somehow, it is changing the field boundaries in the query result. Any hints how to solve this would be highly appreciated. How to repeat: the code calling it: selAttachmentStmt = conn.prepareStatement( " SELECT " + TBL_ATTACHMENT + ".attachment_id, " + " file_size, " + " file_name, " + " content_type, " + " AES_DECRYPT(file_data_blob,) AS file_data_blob " + " FROM " + TBL_ATTACHMENT + " , " + TBL_MSG2ATTA + " WHERE " + TBL_MSG2ATTA + ".msg_id = " + " AND " + TBL_ATTACHMENT + ".attachment_id = " + TBL_MSG2ATTA + ".attachment_id ;"); selAttachmentStmt.setString(1, Globals.getInstance().getAESkey()); selAttachmentStmt.setInt(2, msgId.intValue()); // msg_id if (showAESqueries) { log.debug( "selAttachmentStmt: " + ((DelegatingPreparedStatement) selAttachmentStmt) .getDelegate() .toString()); } crs = selAttachmentStmt.executeQuery(); if (crs == null) { log.debug("row set is null!"); } if (!crs.next()) { log.debug(NO_MORE_SEL_RESULTS + i); throw new DatabaseException( "No attachment found for msg: " + msgId); } else { do { i++; atta = new Attachment(); atta.setAttachmentId( new Integer(crs.getInt("attachment_id"))); atta.setFileSize(new Integer(crs.getInt("file_size"))); atta.setSizeKB(atta.getFileSize()); atta.setFileName(crs.getString("file_name")); //LINE 3715 atta.setContentType(crs.getString("content_type")); atta.setFileStream(crs.getBinaryStream("file_data_blob")); } while (crs.next()); Suggested fix:
