Re: Another custom type handler issue
Do you have to use arrays? How about lists instead? iBATIS (to my knowledge) doesn't support returning arrays. My guess is if you were to have ListAddress addresses and ListCommunication communications (type specification not necessary, just highlighting what its doing) - then iBATIS would do the right thing.

For instance, I have a Client, which contains Address[] arrays and Communication[] arrays. I'd like to populate it with a custom type handler. While I can get the type handler to execute for a single Address or communication object, I can't seem to find a way to get iBatis to understand that it needs to fire a type handler for an array of those objects. An even better way to handle this would be if there were some way I could nest the result maps so that I point the nested cursor to a second result map. Any ideas? Either way, I think I feel another hack coming on :( Thanks, Ken -- Brice Ruth Software Engineer, Madison WI
Re: Very Confused.
Hi Dave, If you're new to Java, I wouldn't suggest trying to setup jPetstore ... that can be kinda tricky even for folks who've been around Java for a while. I would suggest setting up your SqlMap.xml and sql-map-config.xml files, as provided in the tutorial, and then creating a SqlConfig file that initializes the configuration and provides a static method that returns the SqlMapClient instance. Then, create a very simple application that gets a SqlMapClient instance and calls a query and verifies the results. Let me know if that works for you - if you need more guidance (e.g. code), I can help you with that, too.

Re: PreparedStatementLogProxy log4j output with bind variables

Hello All,
I was wondering if there was a way to either request a change or if there
was a way to override the current logging output sent to log4j as shown

From PreparedStatementLogProxy.java
public Object invoke(Object proxy, Method method, Object[] params) throws
Throwable {
try {

if (log.isDebugEnabled()) {
log.debug({pstm- + id + } PreparedStatement: +

log.debug({pstm- + id + } Parameters: + getValueString());
log.debug({pstm- + id + } Types: + getTypeString());
}
.
.
.
The invoke() method simply prints the prepared statement with no bind
variable substitution so the statement is printed with the embedded '?'
placeholders. Is there a way to also include the statement as it would be
sent to the database backend as the actual string with bind variables
replaced. If not is there a way that this Proxy could implement a SPI
interface and adapter that could be configured as a runtime class that
could have a custom Proxy implementation.
Otherwise as it stands I would have to modify the class and rebundle a
custom jar to change the log4j output ...

Re: Oracle 9.2 connection reset problem
One thing that may help ... when I set up a connection pool in Tomcat,
I noticed I could set up time-based connection validation, but I could
also set it up such that whenever a connection was requested by the
application, it would validate the connection BEFORE handing it over.
Regardless of the timing. This quickly took care of similar problems I
was having.
Does the data pool you're using have such an option?

Re: Transactions/BatchStatements
If you're not using startBatch() - then iBATIS will have JDBC run each one individually ... the batching is something that's driver specific (but supported by JDBC), if I recall correctly. It just adds some efficiency.
Each of your inserts runs at the time they are called (without batching), the commit is just a message sent to the database. What *it* does at that time, is implementation dependent.If you look at your JDBC traffic, tho - you'll see it executing each insert when its called, and not waiting for the commit/endTransaction to be called.

And it is important to use an editor that is writing the file in the encoding that you are putting at the top of the XML file. Most editors default to the system encoding, which on Macs would be Mac Roman, and on Windows would be Windows-1252 or maybe ISO-8859-1, depending on the editor. Use good editors! On 4/21/05, Philippe Laflamme [EMAIL PROTECTED] wrote: Daniel, To represent every character from every alphabet, Unicode requires multiple bytes to represent each character (I think 21 bits are required, but most implementations simply use 4 bytes, 32 bits). Since Unicode is cool you're probably interested in using it... On the other hand, you're probably not interested in encoding each of your characters using 4 bytes (quite an overkill for English for example). That's where UTF-8 (or UTF-16) comes in. UTF-8 is a way of encoding the whole Unicode character set using sequences of 8 bit wide characters (1 byte). In other words, it uses multiple (from 1 to 4) 1-byte wide characters instead of one multibyte (32 bits) character. UTF-16 is similar, but uses sequences of 16 bits wide characters. The advantage is that almost all western characters can be represented using one byte, just like to old days... Of course, because of special codes, the character set is not as large as ISO-8859-1 (for example), so certain latin characters we are used to require a specially crafted sequence of 2 (or more) bytes to represent. For example, the letter é (0xE9 for ISO-8859-1) is represented as Ã(c) (0xC3 0xA9 in UTF-8). The XML standard specifies that if the encoding of a file is not specified, it is UTF-8 by default. So, if I were to write é in an UTF-8 file, it wouldn't be read as 0xE9, but as an invalid sequence... It's generaly good practice to set the ecoding of an XML file.

Re: canceling statement?
The cancel() method in JDBC depends on driver support. So, I imagine that every RDBMS has its own way of internally cancelling a running statement, if its even an option.

Re: PaginatedList 'google like' results
The product catalogs on www.powersentry.com, www.newpoint.com,

PaginatedList to provide the Page [1] 2 3 4 ... functionality.
I have a simple Action that looks like this:
public ActionForward gotoPage(

ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
{
DynaActionForm myForm = (DynaActionForm) form;
// Get PRODUCT_INFO_KEY object from session
PaginatedList products = (PaginatedList)
request.getSession().getAttribute(Constants.PRODUCT_LIST_KEY);
if (products != null) {
try {
String page = (String) myForm.get(page);
if (page.equalsIgnoreCase(next)) {
products.nextPage();
} else if (page.equalsIgnoreCase(previous)) {
products.previousPage();
} else {
int pageNum = new
Integer(page).intValue();
products.gotoPage(pageNum);
}
request.setAttribute(Constants.PRODUCT_LIST_CURRENT_PAGE,new
Integer(products.getPageIndex()));
return
mapping.findForward(success.showCategory);
} catch (NumberFormatException e) {
return mapping.findForward(browse);
} catch (RuntimeException e) {
return mapping.findForward(browse);
}
} else {
return mapping.findForward(browse);
}
}
To make this work, when I do the initial query to populate the
PaginatedList, I do as you indicated - one query for the objects, one
query for the count. To hide this double-step, you could put that in
your DAO, if you're using one (I am not).

Re: RES: PaginatedList 'google like' results
Absolutely true ... of course, as I mentioned, I could put this in a
DAO and get around that problem. I just opted not to use a DAO this
time, mostly for expediency's sake (as usual).

Assunto: Re: PaginatedList 'google like' results
The product catalogs on www.powersentry.com, www.newpoint.com,
www.zincklysbro.dk, and www.wilkinsonswordgarden.com all use
PaginatedList to provide the Page [1] 2 3 4 ... functionality.
I have a simple Action that looks like this:
public ActionForward gotoPage(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
{
DynaActionForm myForm = (DynaActionForm) form;
// Get PRODUCT_INFO_KEY object from session
PaginatedList products = (PaginatedList)
request.getSession().getAttribute(Constants.PRODUCT_LIST_KEY);
if (products != null) {
try {
String page = (String)
myForm.get(page);
if (page.equalsIgnoreCase(next)) {
products.nextPage();
} else if
(page.equalsIgnoreCase(previous)) {
products.previousPage();
} else {
int pageNum = new
Integer(page).intValue();
products.gotoPage(pageNum);
}
request.setAttribute(Constants.PRODUCT_LIST_CURRENT_PAGE,new
Integer(products.getPageIndex()));
return
mapping.findForward(success.showCategory);
} catch (NumberFormatException e) {
return mapping.findForward(browse);
} catch (RuntimeException e) {
return mapping.findForward(browse);
}
} else {
return mapping.findForward(browse);
}
}
To make this work, when I do the initial query to populate the
PaginatedList, I do as you indicated - one query for the objects, one
query for the count. To hide this double-step, you could put that in
your DAO, if you're using one (I am not).

Re: Oracle + iBATIS - performance slows to a crawl over time
If its the same application, with the only difference being your JDBC driver, I would be highly suspicious of that driver, first. Assuming that your DataSource configuration is identical between the two applications (other than pointing to different databases using different drivers). I've heard mention of the Oracle 10g driver being quite a bit better than previous versions ... I don't have any particular experience with it, but you might want to give that a shot ... whatever the most recent JDBC driver for Oracle is. Other than that, you may want to look at some profiling tools. If I recall correctly, P6Spy can help you there.

Re: UI for iBatis
True. I guess it depends on the developer and how inuitive the gui is. The one argument made for the gui is that you don't need to worry about violating the DTD with cut and paste errors, which I am prone to make. To each his own on this one. I think a decent IDE with robust XML syntax support will help you out here ... I used to constantly run into run-time errors, but with Eclipse (and, I guess more specifically, the MyEclipse plug-in, $29.95/yr) - the XML editor let's me know of any errors before it gets that far. Saves me time and frustration. Decent code hint/autocompletion for XML, too.

Re: Duplicate Key in Db
I think you need to catch a DaoException, and check its cause. If its cause is a NestedSqlException, you'll need to interrogate that to determine what the real cause was. In your case, it appears a generic exception is thrown by the JDBC driver (com.borland.datastore.driver.SqlState), with a Runtime Error - you'll probably need to parse for Duplicate key to determine if that's what's being thrown. I've had to do something similar ... it certainly isn't elegant, at least not the way I did it! Maybe someone else has a better suggestion.

Re: SOAP attachement (pdf) stored into a db field
My understanding is that streaming data to a BLOB-type field (which
you would likely need to do with a 20MB+ dataset, is still a coming
soon feature - and I believe it requires the latest version of JDBC
(3.0), which may or may not be supported by the SQL Server driver
you're using (are you using jTDS?).
So, I guess what you're likely need to do is use JDBC for this
particular thing ... I'm not certain that even a CustomTypeHandler
will do the trick here for you - though it might, its worth a try.

Since this is not a standard JDBC type (that I know of), you'll probably need to write a custom type handler.

Re: StaleConnectionException
Does Websphere have a mechanism for validating connections, much like
Tomcat's DataSource? We simply supply a validation query that either
gets executed *every* time a DataSource is provided to a client -OR-
after a certain timeout (idle time).
This helped us when our iSeries was bounced regularly Sunday mornings.

And absolutely deserved (by WebSphere).
As I indicated - this (very common) problem is something that the
DataSource implementation provided by Tomcat (gratis) handles very
elegantly. If I setup my DataSource correctly, I can rest assured that
as long as the database is up and authentication is successful, my app
will get a valid connection - it (nor iBATIS) needs to know about
anything else, which is how it ought to be!

That is the single most ridiculous thing I have ever seend. That code

DataSource interface is to hide code like that and deal with
infrastructure issues in a single location, so you don't have to
everywhere.
That DataSource is flawed. I suggest you call IBM and tell them this
exactly. Tell them to fix their crappy datasource and their crappy
app server.
If they refuse (which they probably will if you've already paid them
their annual fees), then you could always wrap the datasource with
your own implementation that will deal with this.

// This exception indicates that the connection to the database is no

And now my question, is there a way to have ibatis automatically retry when
it gets a StaleConnectionException?
Or should each method implement something like below?
public Order getOrder(int orderId) {
Order order = null;
int retryCount = 5;
boolean error = true;
do {
try {
daoManager.startTransaction();
order = orderDao.getOrder(orderId);
for (int i = 0; i order.getLineItems().size(); i++) {
LineItem lineItem = (LineItem) order.getLineItems().get(i);
lineItem.setItem(itemDao.getItem(lineItem.getItemId()));
}
daoManager.commitTransaction();
error = false;
} catch (com.ibm.ejs.cm.pool.ConnectionWaitTimeoutException cw) {

The N+1 selects problem is when you query for n parents, and you need
one extra query for the children. Internally, this happens:
List parents = sqlMap.queryForList( getParents, parameter );
for ( Iterator i = parents.iterator(); i.hasNext(); ) {
Parent p = (Parent) i.next();
List children = sqlMap.queryForList( getChild, p.getId() );
p.setChildren( children );
}
So you end up with 1 query for the parent list, plus one extra for
each parent to get the children = n + 1. Rather inefficient.
This is the problem that 2.0.9 fixes.
Sorry for the confusion.

Re: jpetstore: port to UNIX?
Typically, on UNIX systems, MySQL is only case-sensitive w/r/t table names, not column names. This is because MySQL maps a table name to a file on the file system, which is typically case-sensitive on UNIX systems.

Re: java.util.HashMap as resultClass
The Struts LabelValue bean is quite nice (and simple), though to use
it with iBATIS, I needed to created my own implementation that extends
the standard LabelValue bean, since what ships w/ Struts doesn't have
a default constructor (and hence is not useable with reflection). I
just extend the LabelValue bean and create a no arg constructor that
calls the (string,string) constructor with empty strings - then iBATIS
does the rest.
Using Struts html:optionsCollection is dead-simple then, just provide
it the property that contains the List populated from the iBATIS
queryForList(...) call.
By the way, I've recently really started using the common-beanutils
from Apache, they really are invaluable when working with an MVC
pattern, particularly Struts where you often have ActionForms,
DynaActionForms (map backed), etc. that you need to pull properties
out of and re-populate other beans to pass on to iBATIS or other
layers. Works great :)
Cheers!

If my guess is right. Looks like you trying to do this for your dropdowns. I
do it this way and i
feel it is much cleaner this way.
public interface ValueObject{

/**

All Objects that you are using for Dropdowns will extend the ValueObject, and
they will implement
the three methods. In your case getID() will return SKU, getValue will
return Description. and
for the getSortFieldValue() have an empty implementation. This way the bean
can be used for other
things and also used for dropdowns.
For the dropdowns have a common method that handles them or even struts has
the LabelValue bean.

Pascal,
Another approach is to use a wrapper class at your presentation layer.
After all, this is a presentation layer problem, that is probably
best solved in the presentation layer -- not in the persistence layer.
By aliasing your columns to ID and Value, you've made a change to your
persistence for the sake of a presentation requirement.
Here's my recommendation:
1) Use a real domain model. Avoid Maps. Create a real class that
represents your domain. In this case it looks like a Product class or
something (with properties such as SKU, Description etc.)
2) Map that class with iBATIS properly, using a real parameter class
and result class, with columns mapped to the JavaBean properties.
3) Use that domain object throughout your application. When a
requirement such as a droplist manifests itself, use a wrapper class
to manage special behavior. For example, given a Product class, you
could have a ProductDropListItem that knows how to provide the
appropriate identifier and value to the drop list.
Don't worry about having to make a matching DropListItem for each
class. It's very easy to make a generic one that will work with any
domain class (passed into the constructor). E.g. new DropListItem
(aProduct).
This keeps presentation layer problems out of the persistence layer.
It's also pretty easy to implement.
Cheers,
Clinton

Re: connection parameters
When you say
... in the page there are replaced with question marks '?' ...
I assume you mean a JSP that you're displaying your results in? I
would suggest that you set the character-encoding on the JSP to UTF-8
(change any HTML META tags appropriately as well). From what I can
tell, you're using MySQL - and if memory serves, the parameters you're
using are telling MySQL that the data is stored as ISO-8859-1 and to
pull the data out as Unicode.
Once iBATIS passes the Unicode data on to your presentation layer
(through Struts or otherwise), then it needs to be presented to the
browser appropriately, which in most cases is UTF-8.
That's what we do here, anyway ...

All my pages have character encoding iso-8859-1 and the database too.
I had similar problems in the past if I didn't specify the extra

In my pre-ibatis code I set it in a initServlet like:
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName(getInitParameter(driverClass));
ds.setUrl(getInitParameter(jdbcURL));
ds.setUsername(getInitParameter(user));
