[jboss-user] [JBossCache] - Re: java.io.NotSerializableException: java.lang.Object -Clus
1. Based on some further research, I did not find any "java.lang.Object" declaration in the (Beans/VO, Action forms, Decorators) of the application classes. 2. The Mappings are clean and theres no DB -> field mapping of type Object. 3. Although, In "com.ibatis.db.sqlmap.cache.memory" package, MemoryCacheController has a inner class declaration "StrongReference", which has java.lang.Object declaration.

Well, I think this has got to do with the way Ibatis is implemented. Here's an
example.
private List runQueryForList(SqlStatement localSql, Connection conn, Object
parameterObject, int skipResults, int maxResults, RowHandler rowHandler)
throws SQLException
{
List list;
if(log.isDebugEnabled())
{
log.debug("executeQueryForList: " + name);
conn = ConnectionLogProxy.newInstance(conn);
}
ErrorField errorField = new ErrorField();
if(rowHandler == null)
list = new ArrayList();
else
list = null;
ResultSet rs = null;
PreparedStatement ps = null;
String errorMessage = "Check the SQL statement.";
try
{
sqlMap.incrementExecutionThrottle(conn);
ps = createStatement(conn, localSql, parameterObject);
if(sqlMap.isDriverHintsEnabled() && maxResults != -1 && skipResults
!= -1)
{
ps.setFetchSize(maxResults + skipResults);
ps.setMaxRows(maxResults + skipResults);
}
errorMessage = "Check the Parameter Map (or inline parameters).";
applyParameterMap(localSql, ps, parameterObject, errorField);
errorField.errorField = null;
errorMessage = "Check the SQL statement.";
rs = ps.executeQuery();
for(int i = 0; i < skipResults; i++)
if(!rs.next())
break;
errorMessage = "Check the Result Map.";
int n = 0;
if(rowHandler == null)
{
for(; (maxResults == -1 || n < maxResults) && rs.next(); n++)
{
Object object = applyResultMap(conn, rs, null, errorField);
list.add(object);
}
errorField.errorField = null;
} else
{
for(; (maxResults == -1 || n < maxResults) && rs.next(); n++)
{
Object object = applyResultMap(conn, rs, null, errorField);
rowHandler.handleRow(object);
}
errorField.errorField = null;
}
}
catch(Throwable t)
{
Throwable tt = unwrapProxyException(t);
String msg = "";
if(errorField.errorField != null)
msg = "Error executing '" + name + "' in '" + resourceName +
"'. " + errorMessage + " Check the '" + errorField + "' property. Cause: " + t;
else
msg = "Error executing '" + name + "' in '" + resourceName +
"'. " + errorMessage + " Cause: " + t;
if(log.isErrorEnabled())
log.error(msg, t.fillInStackTrace());
if(t instanceof SQLException)
throw (SQLException)t;
else
throw new SQLException(msg);
}
finally
{
closeResultSet(rs);
closeStatement(ps);
sqlMap.decrementExecutionThrottle(conn);
}
notifyListeners();
return list;
}
BELOW IS THE applyResultMap METHOD
private Object applyResultMap(Connection conn, ResultSet rs, Object
resultObject, ErrorField errorField)
throws SQLException
{Object object = resultObject;
String typeName = null;
if(getResultMapName() != null)
{
ResultMap map = getSqlMap().getResultMap(getResultMapName());
typeName = map.getClassName();
if(object == null)
object = instantiate(map.getClassName());
ResultMapping mapping;
for(Iterator names = map.getMappedPropertyNames(); names.hasNext();
setBeanProperty(mapping, object, conn, rs, errorField))
{
String propertyName = (String)names.next();
mapping = map.getResultMapping(propertyName);
}
} else
if(resultClass != null)
{
typeName = resultClass;
if(object == null)
object = instantiate(resultClass);
if(object instanceof BaseValue)
{
ResultMapping mapping = new ResultMapping();
mapping.setPropertyName("value");
mapping.setColumnName("VALUE");
mapping.setColumnIndex(new Integer(1));
setBeanProperty(mapping, object, conn, rs, errorField);
} else
if(object instanceof Map)
{
ResultSetMetaData rsmd = rs.getMetaData();
int i = 0;
for(int n = rsmd.getColumnCount(); i < n; i++)
{
String columnName = rsmd.getColumnLabel(i + 1);
((Map)object).put(columnName, rs.getObject(i + 1));
}
} else
{
autoMapResultSet(conn, rs, object, errorField
[jboss-user] [JBossCache] - Re: java.io.NotSerializableException: java.lang.Object -Clus
We investigated the application code and Ibatis sources. 1. All the application classes (Beans, Actionforms, Decorators) are serializable. (This takes care of all the objects in chain) 2. We suspected that Ibatis could be problem area and made all the classes serializable (For sanity sake) Yet the java.io.NotSerializableException: java.lang.Object is seen. Its becomming impossible to understand what could be the reason for this. Help Appreciated.
