Problem with JDBC & Struts Connection Pool (possible to reconnect?)

[mech]

Hi,

I'm running Tomcat 4.1.18 on Solaris 9 with a local MySQL 3.23.54-max
(InnoDB) database on port 3307 using started with mysqld (not
safemysld...difference btw?).

After not using any connection over night for let's say 12 hours or
more, I get SQLExceptions next morning:

"java.sql.SQLException: Communication link failure:
java.net.SocketException"

In my application I use JDBC for Tomcats security realm feature and
form-based auth. When I try to login for the first time, I get this
error log (see below), but if I try to login twice the db connection
seems to get reset automatically. (A solution I could live with,
although I have now idea why the connection was cut while it should be
idle overnight)

Unfortunatelly my struts connection pool that I use in my application's
data access classes doesn't get reinitialized after such a
SocketException (see below). The only solution so far was to reload or
stop/start the webapp with the Tomcat manager. Bad solution

In my struts-config.xml I already have something to reconnect (see
below), but it obviously didn't do the trick with my
"mysql-connector-java-2.0.14.jar" J/Connector. I simply lost the
connection somehow...

Can anyone give my an hint what happens to my MySQL connections? I don't
seem to have a problem if I send a query from time to time, but if I
wait too long and do nothing, I'm cut off... :-(

In case there's no way to stop this, is there a solution how to tell my
application (a java code snippet would be great...) to reinitialize the
Struts connection pool when this exception is thrown. For Tomcat's
JDBCRealm it is done somehow, how can I reset the MySQL connection for
Struts? I think I could live with a reconnect on the second try for a
query.

Thanks you!
Michael

PJA libraries

[Yakov Belov]

Dear All,

this might be the wrong mailing-list to send this question to, however maybe not.

I am using PJA (pure java graphics implementation) libraries for my chart drawing with 
Struts on Tomcat.

To use these libraries I need to change the system a bit, like this:

System.setProperty ("awt.toolkit", "com.eteks.awt.PJAToolkit");
System.setProperty ("java.awt.graphicsenv", "com.eteks.java2d.PJAGraphicsEnvironment");
System.setProperty ("java.awt.fonts", "/usr/share/fonts/default/TrueType");

and I place all the jar files under WEB-INF/lib for the application. However when I 
try to draw an image, I receive:

java.lang.Error: Could not find class: com.eteks.java2d.PJAGraphicsEnvironment

where com.eteks.java2d.PJAGraphicsEnvironment is a class in one of the jar files. What 
might be the problem?

Thanks in advance,
Yakov

P.S. I should try Tomcat mailing list as well.

Re: changing ActionForm to be a Java interface

[Dan Jacobs]

Hi Mark,

Contravariance is generally easiest to understand in the context of 
aggregation.  Consider the parameterized types (looking ahead to Java 
generics) List and List, and variables fruitList and 
bananaList, and assuming that Banana is a subtype of Fruit.  Even though 
it should be ok in a polymorphic language to assign a value of [static] 
type Banana to a variable with a type of Fruit, it should be legal to 
assign a List to the variable fruitList.  If you did, then 
static typing would indicate that you could add an Apple to that list, 
and that would be wrong!  It has to do with *static* (i.e. compile-time) 
typing, which is the kind of typing that makes most Java programs easy 
to understand.

There are some excellent papers by Luca Cardelli that deal with this in 
a much more rigorous manner, but they're not fun to read to your friends 
at parties :-).

In the context of this thread, contravariance is the mathmatical 
relation between types that exposes the dark side of inheritance.  This 
usually shows up when an "is-a-part-of" relationship is implemented as 
an "is-a-kind-of" relationship.  This results in a subclass that has 
operations that don't make sense for the superclass, or are just 
contradictory when applied to the superclass.  That's what I'm claiming 
is the problem with the current implement of form-beans.

Based on the oft misunderstood property of contravariance, I *do* 
conclude that form-beans should not be subtyped from Java Beans, for the 
reason that subtypes are never supposed to have fewer behaviors than 
their supertypes.  It's customary in good object-oriented design to use 
delegation rather than subclassing to use only a selected subset of 
behaviors from another kind of thing.  If Struts is saying that a 
form-bean should never act like a bean in such-and-such manners, then it 
follows that form-beans should not be beans.  This *is* an architecture 
issue.

Re: AW: Refresh on MSIE, PLEASE HELP!! NOT SOLVED

[Karim Saloojee]

Hi

I know that in IE you sometimes have to set the response headers in Java,
e.g:

<%
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Cache-Control", "no-cache");
%>

Put that in skel.jsp.

One last thing, make sure you have cleared out your IE cache before
re-testing (Tools > Internet Options > Delete Files > Delete All Offline
Content > Ok).

Good Luck,
Karim

Display values after validation (was RE: action input)

[Susan Bradeen]

But by using an action path for input instead of a JSP, isn't the 
ActionForm reset, so you no longer have your form values to show in the 
JSP again? How do you redisplay the incorrect values the user typed into 
the JSP?

Re: (Another test) App Modules and multiple tiles configuration files...

 According to the log, both factories are loaded. So, there should be 
something wrong. Can you send me directly ([EMAIL PROTECTED]) your 
simple example (zip or war), so I can reproduce the problem ?

From my limited knowledge it looks like both Tiles definition 
factories are loaded. Yet, if I do not include the knowledge defs in 
the first factory load they are not seen correctly by the knowledge 
module.

I'm open for any suggestions.


Thanks, ajTreece

Thanks Cedric for replying...

Here is what is happening and I'm not convinced that it is how it 
should work

I have two modules A and B (for simplicity). They are defined in 
web.xml as follows:


  config
  /WEB-INF/config/struts-A-config.xml


  config/B
  /WEB-INF/config/struts-B-config.xml


I have (at this time) three tiles defs files... COMMON, A, and B. 
The COMMON defs handle the main page layout and other tiles common 
to all modules for this site. Tiles defs A and B are specific to 
that particular module. Here is how they are defined in each module 
xml file which is not working:

...struts-A-config.xml...

  
 value="/WEB-INF/config/tiles-COMMON-defs.xml,
/WEB-INF/config/tiles-A-defs.xml" />
  


...struts-B-config.xml...

  
 value="/WEB-INF/config/tiles-COMMON-defs.xml,
/WEB-INF/config/tiles-B-defs.xml" />
  



The only way I can get the tiles to display correctly is if I 
include B's tiles defs in the module A's plugin as follows:

 ...struts-A-config.xml...

  
 value="/WEB-INF/config/tiles-COMMON-defs.xml,
/WEB-INF/config/tiles-A-defs.xml,
/WEB-INF/config/tiles-B-defs.xml" />
  


Also note, that module B's plugin must still include both the COMMON 
and B's tiles defs to work. It is almost acting like ALL of the 
tiles defs need to be initialized via first plugin accessed via 
web.xml. Is there something wrong or is that the way it is suppose 
to work?

Thanks again, aj

Am I reading the books / docs incorrectly? I am assuming that each

 Yes, each module have its own definitions file when 
moduleAware="true".
 Can you check the servlet logs to see if there is one or two 
factory loaded ?


Has anyone else had success using multiple application modules

  Yes, me ;-). The tiles-documentation.war use modules with

Re: ActionErrors getting lost between action and JSP

[Giri Alwar]

When  you call the saveErrors(...) method in the Action class' execute
method, Struts will store the ActionErrors object under the default request
attribute name "org.apache.struts.action.ERROR". In the JSP, when you add
the empty html:errors tag: , Struts will look for this
attribute in the request and display the errors. There is generally no need
for you to save the errors under a different attribute name in the request
in your Action class or specify a "name" attribute in the html:errors tag.

You stated that you were saving the errors under the name "errors" in your
Action class but your earlier code snippet shows that you were just calling
saveErrors(...). Are you saving the errors yourself under a different
attribute name? If so, are you doing this in addition to or in place of
calling saveErrors()? It is not clear to me what your execute() method looks
like.

Re: Struts app design for multiple client types

[Kris Schneider]

Thanks for tip, I took a quick look. I have to say the first example 
made my head spin.

http://home.attbi.com/~danjacobs/jplates.com/examples/test/ClassInfo1.jplate

It just doesn't look like the kind of approach that would appeal to the 
no-scriptlet faithful (which is where I firmly plant myself). Of course, 
I didn't get much beyond the example, but I'm not too inclined to keep 
investigating at his point. The front page of the site sounds great 
though...

Hi Kris,

Unless your application data starts off as XML in the first place, and 
assuming you're a Java programmer, I recommend using JPlates 
(http://www.jplates.com) for multi-target transformations.  JPlates is a 
fully object-oriented template language, and I've used it very 
sucessfully both for generating HTML and for transforming XML.

The classic text (and the one that really popularized the notion of caring
about the "design patterns" concept) is by four authors colloquially known
as the "Gang of Four" (or GoF):

  Gamma, Helms, Johnson, Vlissides, DESIGN PATTERNS:  ELEMENTS
OF REUSABLE OBJECT-ORIENTED SOFTWARE, Addison-Wesley, 1995.

Punch "design patterns" into Google or Amazon and you'll find lots of info
sources, including many focused on Java or J2EE (servlet/JSP are the
standard web tier technologies for J2EE).

On "when to use which patterns", it's a skill that comes from practice and
experience.  However, I'd start by seeing if your problem space is similar
to things in the "Applicability" section of many pattern descriptions.
And check the "Consequence" (both good and bad) to see if applying this
pattern would help you towards better results.

There's some philosophical and introductory stuff on the JUnit web site
(www.junit.org).  But JUnit is primarily a tool to implement a philosophy
-- the philosophy of "unit testing" as a discipline.  You might want to
search for that term to get some references.

One thing you might want to do is download the source code to a small bit
of code that is heavily unit tested (such as commons-beanutils that Struts
uses), and see what we did -- the intent was to write tests for every
possible invocation of every possible method.  Having the tests in place
does two primary things for us:
* Documented proof that the method being tested behaves
  according to it's (Javadoc) specification
* Protection from future developers making changes and
  inadvertently changing the behavior that users of the
  code depend on.

You can grab a source distro of commons-beanutils (pick any recent nightly
build) at:

  http://jakarta.apache.org/builds/jakarta-commons/nightly/commons-beanutils/

and look in the "src/test" directory for the unit tests.

Unit testing is also one of the foundations of a development approach
called Extreme Programming (XP), so there will be lots of pointers and
examples in the information about XP as well.

Well, the web runs on HTTP.  The facts that HTTP is synchronous
(request/response) oriented, and stateless, are critically important.
The facts of how security and cookies work are driven by the HTTP
standards.  Little details like the fact that HTTP headers are sent at the
beginning of a message, so you can't usually add them at the end of your
servlet, will help you avoid lots of frustration.

It's sort of like learning to drive -- if you focus on the mechanics of
steering a car, but don't understand the driving laws in your country,
you're likely to have a lot more problems than if you had studied both
:-).

It's fine to learn the details as you need them, but if you haven't done
a pretty complete overview, then how do you know what's there that you
*haven't* needed yet?  Servlets are foundational to understanding JSP.

I will post here when I am ready soon. Glad there is interest, I got

As I plan to donate materials to Jakarta I would like to see if some

It's probably worth throwing in "installing and configuring a servlet

know how
to set Tomcat up on your development PC.

I wonder if Tomcat is used in real and critical application by major 
companies? What other servlet containers out there? I once played

FW: Problem with JDBC & Struts Connection Pool (possible to reconnect?) : Solution/Fix: J/Connector kills unused connections after 8 hours

[mech]

You can ignore my last email or read through if you encounter similar
problems and need a fix.
I just found out from the MySQL J/Connector documentation that
connections are cut off after 8 hours of inactivity.


"I have a servlet/application that works fine for a day, and then stops 
  working overnight".

  Resolution: 

  MySQL closes connections after 8 hours of inactivity. You either
  need to use a connection pool that handles stale connections or use
the 
  "autoReconnect" parameter (see "USAGE AND INSTALLATION"). [...]

  

I guess (from my bad experience) that the Struts connection pool can't
handle stale connections so I just added "autoReconnect" to my
struts-config.xml. I hope this fix keeps my webapp work overnight this
time... Tomcat's JDBCRealm seems to handle stale connections
automatically... 
Maybe this would be a nice to have thing for the Struts connection pool,
too?!

BTW: You cannot use "set-property" for those special properties like
"autoReconnect" or "profileSql". They have to be in the connectionURL
like this (I tried it differently with "profileSql" but nothing happend
on stderr):

Use instead similar to:


Thanks anyway.

Subject: Problem with JDBC & Struts Connection Pool (possible to
reconnect?)


Hi,

I'm running Tomcat 4.1.18 on Solaris 9 with a local MySQL 3.23.54-max
(InnoDB) database on port 3307 using started with mysqld (not
safemysld...difference btw?).

After not using any connection over night for let's say 12 hours or
more, I get SQLExceptions next morning:

"java.sql.SQLException: Communication link failure:
java.net.SocketException"

In my application I use JDBC for Tomcats security realm feature and
form-based auth. When I try to login for the first time, I get this
error log (see below), but if I try to login twice the db connection
seems to get reset automatically. (A solution I could live with,
although I have now idea why the connection was cut while it should be
idle overnight)

Unfortunatelly my struts connection pool that I use in my application's
data access classes doesn't get reinitialized after such a
SocketException (see below). The only solution so far was to reload or
stop/start the webapp with the Tomcat manager. Bad solution

In my struts-config.xml I already have something to reconnect (see
below), but it obviously didn't do the trick with my
"mysql-connector-java-2.0.14.jar" J/Connector. I simply lost the
connection somehow...

Can anyone give my an hint what happens to my MySQL connections? I don't
seem to have a problem if I send a query from time to time, but if I
wait too long and do nothing, I'm cut off... :-(

In case there's no way to stop this, is there a solution how to tell my
application (a java code snippet would be great...) to reinitialize the
Struts connection pool when this exception is thrown. For Tomcat's
JDBCRealm it is done somehow, how can I reset the MySQL connection for
Struts? I think I could live with a reconnect on the second try for a
query.

Thanks you!
Michael

java.lang.String question disguised as an ActionForm question

[Jagdish Arora]

ok, though this problem came up dealing with ActionForms, I completely
understand that this is a fundamental Java question, nothing more, so I will
pose it as that only.  Also, I am prepared for taking some
thisQuestion(OrYou)DoesntDeserveToBeHere flak:

String s1 = "" + null;
System.out.println ("s1: " + s1);
if (s1 == null)
System.out.println ("s1 is null");
else
System.out.println ("s1 is not null");

produces output:
s1: null
s1 is not null

While if I replace the first line by, String s1 = "";
then it produces output:
s1:
s1 is not null

(which I have no problem with).

Question: Why does the 1st line of the output of the first case read s1:
null  ?

AW: How to set a parameter in an action

[Oliver Kersten]

Hi,
thanks for your answer, now we have solved the problem.

We are using our own class (ActionForwardWithParameter) which is extended
from ActionForward. Our class gets the original ActionForward as a parameter
and then (with some tricks) we use our own method to add a parameter. The
return value of the execute() method is our own ActionForwardWithParameter.

ciao Oliver.

Betreff: Re: How to set a parameter in an action


Servlet API doesn't allow you to write request attributes (parameters,
headers...)

You can try to forward to a new ActionForward object, build with the mapping
to your "another" action, adding needed parameter with GET syntax :
...
return new ActionForward( NEXT_ACTION_URL + "?param=" + paramValue );
(I'm not sure it will work...)


Another solution is to put param value in request and forward to a JSP that
will redirect browser to the NEXT_ACTION_URL with param added :

# in your action:
request.setAttribute("param", paramValue);
return new ActionForward( "redirect.jsp" );


# redirect.jsp :

  ">


document.forms[0].submit();

Why would it be necessary to add XSLT functionality to Struts tags, when
the  tag already exists.  Or, to put it another way, what
does the  tag (by itself) *not* do that you think would be
helpful?

My gut feel is that further XMLish integration into Struts itself should
focus more on things like defining a processing pipeline in struts-config
-- sort of like Cocoon's sitemap, but not quite so much work.  In other
words, focus on enriching the controller functionality.

Tag libraries like JSTL are designed to interoperate with each other, so
if you happen to be using JSP for output, it makes perfect sense (at least
to me) to use them.

RE: [OT] Date format

[Andrew Hill]

Your best bet is to use the static factory methods in the DateFormat class.

ie:
Locale locale = getLocale(request); //Use struts Action method to get locale

dateTimeFormat =
ateFormat.getDateTimeInstance( DateFormat.SHORT,DateFormat.SHORT, locale);
dateFormat = DateFormat.getDateInstance( DateFormat.SHORT, locale);
timeFormat = DateFormat.getTimeInstance( DateFormat.SHORT, locale);

Its all in the javadocs you know. :-)


In case you were wondering how the java.util.Date.toString() works, heres
its source code:

public String toString() {
DateFormat formatter = null;
if (simpleFormatter != null) {
formatter = (DateFormat)simpleFormatter.get();
}
if (formatter == null) {
/* No cache yet, or cached formatter GC'd */
formatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz ",
 Locale.US);
simpleFormatter = new SoftReference(formatter);
}
synchronized (formatter) {
formatter.setTimeZone(TimeZone.getDefault());
return formatter.format(this);
}
}

Group of radio buttons with indexed="true" within nested iterate

[Yujin Kim]

Hi

I'm having some issues with indexed="true" and nested iterate tags. I'm
hoping some of you would be able to give me some directions.  BTW, I had
to strip out the orignial source code.  I apologize for that if this
makes difficult to follow.  I'd be happy to provide more details in
private channel.

My jsp looks like this:








theForm is the form bean contains the following:
itemList - java.util.List of ItemBean
idValueBeanList - java.util.List of IdValuBean which represents
lookup table in the database

ItemBean is a simple bean that has some properties in primitive data
types that represents a row.
Say ItemBean holds the following properties [ int itemId; int
itemTypeId; String itemName ]

IdValueBean is another simple bean that contains id and value of a
lookup table.
We can presume that IdValueBean represents a single in item_type_lu
lookup table.

So what I need to do is have the html come out as follows
[input type="radio" name="item[0].itemTypeId" value"1"]
[input type="radio" name="item[0].itemTypeId" value"2"]
[input type="radio" name="item[0].itemTypeId" value"3"]
[input type="radio" name="item[0].itemTypeId" value"4"]
[input type="text" name="item[0].itemName" value="some item
name"]

[input type="radio" name="item[1].itemTypeId" value"1"]
[input type="radio" name="item[1].itemTypeId" value"2"]
[input type="radio" name="item[1].itemTypeId" value"3"]
[input type="radio" name="item[1].itemTypeId" value"4"]
[input type="text" name="item[1].itemName" value="some item
name"]

..

But with the above jsp code, I end up having an html code that looks
like this:
[input type="radio" name="item[1].itemTypeId" value"1"]
[input type="radio" name="item[2].itemTypeId" value"2"]
[input type="radio" name="item[3].itemTypeId" value"3"]
[input type="radio" name="item[4].itemTypeId" value"4"]
[input type="text" name="item[0].itemName" value="some item
name"]

[input type="radio" name="item[1].itemTypeId" value"1"]
[input type="radio" name="item[2].itemTypeId" value"2"]
[input type="radio" name="item[3].itemTypeId" value"3"]
[input type="radio" name="item[4].itemTypeId" value"4"]
[input type="text" name="item[1].itemName" value="some item
name"]

...

I was trying to learn how to use nested tag hoping it might solve the
problem, but I didn't quite get how to use it.

Any help would be greatly appreciated.

If you're running on a Servlet 2.3 / JSP 1.2 container, JSTL is right up
your alley:

  
...
  

You can get the code that is the basis of the reference implementation
from:

  http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html

Struts 1.1b3 includes a "struts-el" package (in the contrib directory)
that supports the same kinds of expressions in many Struts tags.  It also
requires Servlet 2.3 / JSP 1.2, and JSTL, to operate.

problem with ResultSetDynaClass

[usha]

Hi

i am stuck with this error from past  2 hrs. can any body tell me what i 
am doing wrong here
i am writing the following code to use with struts

 con = CxcSvcLoc.getInstance().getCxcDataSource().getConnection();
 stmt = con.createStatement();
  rs = stmt.executeQuery("select ivtransbatchid from ivtranshdr");
  ResultSetDynaClass rsdc = new ResultSetDynaClass(rs);
  BasicDynaClass bdc = new BasicDynaClass("foo", 
BasicDynaBean.class, rsdc.getDynaProperties());

  Iterator rows = rsdc.iterator();
  while (rows.hasNext())  {
DynaBean row = (DynaBean) rows.next();
DynaBean newRow = bdc.newInstance();
PropertyUtils.copyProperties(newRow, row);
results.add(row);
  }

the above code is giving the error msg like this , the batchid that i am 
seleting from database is of type Integer.

Session lost between Actions using mapping.findForward(HELP)

[Jason Yam]

Hi everyone,
 
 I almost finish my project but I have one more problem: "session lost".
I save a session variable named "username" in ProcessLogonFormAction before
I use findForward("homepage") to go to my homepage "homepage.jsp" through
the action DisplayHomePageAction.  DisplayHomePageAction will check the
existence of the session variable "username" to decide whether to forward
the request to the homepage.
 
For the first time, I can see homepage.jsp after clicking the submit
button of the logon.jsp and so DisplayHomePageAction can see the correct
session varaible "username".  However, when I click a link that runs
DisplayHomePageAction again, it shows the logon page instead of homepage.jsp
because the session variable "username" is lost.  In debugger, I see the
session ID is different between Step 6 and Step 7 .  I don't think I have
used session.removeAttribute() and session.invalidate().
 
Here is my program flow:
 
1. DisplayLogonFormAction => 2. logon.jsp => 3. click submit => 4.
ProcessLogonFormAction => 5. DisplayHomePageAction => 6.homepage.jsp
=>7. DisplayHomePageAction => 8.homepage.jsp
 
Is it related to URL not encoded (JSession ID)?  Can someone show me how
to make it work? 
 
Thank you
 
Jason

Hello,

but the following doesn't:

Which means subdirectories within the context are not recognized by

How can I fix this?
Thanks in advance.

 form[oRequired[x][0]].type == 'radio' ||
 form[oRequired[x][0]].type == 'password') &&

Please let me know if anyone knows how to fix this problem.

Validator and Form Bean

[Suresh Addagalla]

Hi,

Does Struts Validator *pass back* the form bean object if a validation
fails? Or does it pass back only the errors?

My scenario is as follows. I have a page for creating a "Service". I
enter all the data and submit it. Assume that the validation fails. In
this case, along with the error message, I should display the submitted
values so that the user can correct them and re-submit. But now, my
whole form is not getting displayed because I am not getting the form
bean back. Any thing I am missing? **Must the form bean be in session
scope if I want this functionality?**

Thanks,
Suresh

I applied struts in the simplest form and received the below error message.
This application resides on a Weblogic 6.0 server.

Scenario:
It involves two JSP's, two form classes and an action class.  The Index.jsp
is loaded first where you key in the username and click the ok submit
button. It takes you to the other jsp, accept.jsp, which displays the user
name.

In the backend, when you click the button on the index.jsp, the value of
the username is taken to the form bean and in the action class the data
from the form bean of the index.jsp is retrieved and stored in the form
bean of the the accept.jsp and the jsp is loaded.  It automatically gets
the data from the form bean and displays  it on  the accept.jsp.


Problem:
The problem I'm having is once I click on the ok button from the index.jsp
I get the following error message displayed from weblogic:

Re: Indexed Properties and Population

David says:
"One implementation that should work based on your example
as long as you are willing to create a child factory is in the commons
collection package and is ListUtils.lazyList, which takes a List and
factory."

I have used this as well, in combination with the nested tag library.
We have  a page that displays and updates a List of Value Objects where
each have two internal Lists of Value Objects.
The structure of value objects are sent to me from the back end as such:

CustomerList
  CustomerVo 1
creditVo1   invoiceVo1
creditVo2   invoiceVo2
.   .

  CustomerVo2
creditVo1   invoiceVo1
creditVo2   invoiceVo2

I would be curious to know  this would done without the nested tags and

on demand. You can intercept gets and auto-extend the underlying
Collection. One implementation that should work based on your example
as long as you are willing to create a child factory is in the commons

collection package and is ListUtils.lazyList, which takes a List and
factory.

>>> [EMAIL PROTECTED] 01/16/03 02:31PM >>>
I have an ArrayList on a form... let's call the form Parent and the
ArrayList Children.

If I have:

private ArrayList children;

public void setChildren(int index, ChildForm childForm) {
 this.children.set(index, childForm);
}

Then saving my form results in a NPE for BeanUtils.copyProperties.  If
I
create a whole bunch of objects in the ArrayList in the constructor -
I
avoid this problem:

public ParentForm () {
children = new ArrayList(100);
for (int i=0; i < 100; i++) {
children.add(new ChildForm());
}

But I'm guessing that this fits better into the reset(mapping,
request)
method of my form.  My question is - how do I determine how many there
are?
Is there something in the request this this information - or should I
set a
hidden field with the number of children?

Thanks,

Matt

Re: Struts application

[Daniel Jaffa]

That is a great picture of what you are doing, but your question does not
help anyone help you.

1 Did you do any logging in your action to see where the null pointer is
being generated.  At least put some System.err.println(); in you code to see
where you are failing.
2. Are you sure that it is even getting to you action.
3. Is your manager causing the problem.

I use weblogic 6.1sp2 and use Log4J to log my app, if you are not currently
using it I would suggest that you do.

Subject: Problem with JDBC & Struts Connection Pool (possible to
reconnect?)


Hi,

I'm running Tomcat 4.1.18 on Solaris 9 with a local MySQL 3.23.54-max
(InnoDB) database on port 3307 using started with mysqld (not
safemysld...difference btw?).

After not using any connection over night for let's say 12 hours or
more, I get SQLExceptions next morning:

"java.sql.SQLException: Communication link failure:
java.net.SocketException"

In my application I use JDBC for Tomcats security realm feature and
form-based auth. When I try to login for the first time, I get this
error log (see below), but if I try to login twice the db connection
seems to get reset automatically. (A solution I could live with,
although I have now idea why the connection was cut while it should be
idle overnight)

Unfortunatelly my struts connection pool that I use in my application's
data access classes doesn't get reinitialized after such a
SocketException (see below). The only solution so far was to reload or
stop/start the webapp with the Tomcat manager. Bad solution

In my struts-config.xml I already have something to reconnect (see
below), but it obviously didn't do the trick with my
"mysql-connector-java-2.0.14.jar" J/Connector. I simply lost the
connection somehow...

Can anyone give my an hint what happens to my MySQL connections? I don't
seem to have a problem if I send a query from time to time, but if I
wait too long and do nothing, I'm cut off... :-(

In case there's no way to stop this, is there a solution how to tell my
application (a java code snippet would be great...) to reinitialize the
Struts connection pool when this exception is thrown. For Tomcat's
JDBCRealm it is done somehow, how can I reset the MySQL connection for
Struts? I think I could live with a reconnect on the second try for a
query.

Thanks you!
Michael

RE: contravariance

Hi Mark,

Contravariance is generally easiest to understand in the context of 
aggregation.  Consider the parameterized types (looking ahead to Java 
generics) List and List, and variables fruitList and 
bananaList, and assuming that Banana is a subtype of Fruit.  Even though 
it should be ok in a polymorphic language to assign a value of [static] 
type Banana to a variable with a type of Fruit, it should be legal to 
assign a List to the variable fruitList.  If you did, then 
static typing would indicate that you could add an Apple to that list, 
and that would be wrong!  It has to do with *static* (i.e. compile-time) 
typing, which is the kind of typing that makes most Java programs easy 
to understand.

There are some excellent papers by Luca Cardelli that deal with this in 
a much more rigorous manner, but they're not fun to read to your friends 
at parties :-).

In the context of this thread, contravariance is the mathmatical 
relation between types that exposes the dark side of inheritance.  This 
usually shows up when an "is-a-part-of" relationship is implemented as 
an "is-a-kind-of" relationship.  This results in a subclass that has 
operations that don't make sense for the superclass, or are just 
contradictory when applied to the superclass.  That's what I'm claiming 
is the problem with the current implement of form-beans.

It only resets numeric. For example, there is an amount property of your
bean which is a Double. If you enter abc and submit, abc is reset to 0.0. To
avoid this, change Double to String so struts can keep the original value.

I know that in IE you sometimes have to set the response headers in Java,
e.g:

<%
response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires",
0); response.setHeader("Cache-Control", "no-cache"); %>

Put that in skel.jsp.

One last thing, make sure you have cleared out your IE cache before
re-testing (Tools > Internet Options > Delete Files > Delete All Offline

The classic text (and the one that really popularized the notion of caring
about the "design patterns" concept) is by four authors colloquially known
as the "Gang of Four" (or GoF):

  Gamma, Helms, Johnson, Vlissides, DESIGN PATTERNS:  ELEMENTS
OF REUSABLE OBJECT-ORIENTED SOFTWARE, Addison-Wesley, 1995.

Punch "design patterns" into Google or Amazon and you'll find lots of info
sources, including many focused on Java or J2EE (servlet/JSP are the
standard web tier technologies for J2EE).

On "when to use which patterns", it's a skill that comes from practice and
experience.  However, I'd start by seeing if your problem space is similar
to things in the "Applicability" section of many pattern descriptions. And
check the "Consequence" (both good and bad) to see if applying this pattern
would help you towards better results.

There's some philosophical and introductory stuff on the JUnit web site
(www.junit.org).  But JUnit is primarily a tool to implement a philosophy
-- the philosophy of "unit testing" as a discipline.  You might want to
search for that term to get some references.

One thing you might want to do is download the source code to a small bit of
code that is heavily unit tested (such as commons-beanutils that Struts
uses), and see what we did -- the intent was to write tests for every
possible invocation of every possible method.  Having the tests in place
does two primary things for us:
* Documented proof that the method being tested behaves
  according to it's (Javadoc) specification
* Protection from future developers making changes and
  inadvertently changing the behavior that users of the
  code depend on.

You can grab a source distro of commons-beanutils (pick any recent nightly
build) at:

 
http://jakarta.apache.org/builds/jakarta-commons/nightly/commons-beanutils/

and look in the "src/test" directory for the unit tests.

Unit testing is also one of the foundations of a development approach called
Extreme Programming (XP), so there will be lots of pointers and examples in
the information about XP as well.

Well, the web runs on HTTP.  The facts that HTTP is synchronous
(request/response) oriented, and stateless, are critically important.
The facts of how security and cookies work are driven by the HTTP
standards.  Little details like the fact that HTTP headers are sent at the
beginning of a message, so you can't usually add them at the end of your
servlet, will help you avoid lots of frustration.

It's sort of like learning to drive -- if you focus on the mechanics of
steering a car, but don't understand the driving laws in your country,
you're likely to have a lot more problems than if you had studied both
:-).

It's fine to learn the details as you need them, but if you haven't done
a pretty complete overview, then how do you know what's there that you
*haven't* needed yet?  Servlets are foundational to understanding JSP.

Susan,

since the request is being forwarded (and not redirected) , then it (the
request) still contains the invalid user input and although the form is
being reset, since the request still has the user input, the form fields
should be repopulated with the users original (incorrect) values.

RE: Display values after validation (was RE: action input)

Like I said, "Try it and see."  I've never tried it, and apparently no one

But by using an action path for input instead of a JSP, isn't the 
ActionForm reset, so you no longer have your form values to show in the 
JSP again? How do you redisplay the incorrect values the user typed into 
the JSP?

There's no such thing.  You are thinking of the M$ VBScript debugger, which

RE: [OT] Date format

Hi,

What I am looking for is how to display the *format*, and not how to
display a date in a given format. So, there doesn't seem to be anything
provided with the API.

I need a method like "toPattern()" of SimpleDateFormat in the DateFormat
class because getDateInstance() returns me DateFormat and not
SimpleDateFormat.

RE: java.lang.String question disguised as an ActionForm question

[Andrew Hill]

Because in a string concatenation operation null will be converted to "null"
automatically.
Useful in debugging this is.
ie:
log.debug("value of bob=" + bob);

is a lot easier than always having to write

if(bob == null)
  log.debug("value of bob=null");
else
  log.debug("value of bob=" + bob);

Which you would have to do if it was converted to an empty string, or threw
a NullPointerException if you tried to output it...

Validator and Form Bean

[Suresh Addagalla]

Hi,

Does Struts Validator *pass back* the form bean object if a validation
fails? Or does it pass back only the errors?

My scenario is as follows. I have a page for creating a "Service". I
enter all the data and submit it. Assume that the validation fails. In
this case, along with the error message, I should display the submitted
values so that the user can correct them and re-submit. But now, my
whole form is not getting displayed because I am not getting the form
bean back. Any thing I am missing? **Must the form bean be in session
scope if I want this functionality?**

Thanks,
Suresh

Your best bet is to use the static factory methods in the DateFormat class.

ie:

dateTimeFormat =

dateFormat = DateFormat.getDateInstance( DateFormat.SHORT, locale);

Its all in the javadocs you know. :-)

That's pretty curious; I would never have thought to do this, and wonder why
you are.  Anyway, it seems pretty obvious that s1 ==  + null
and s1 != null, so it fails the s1 == null test.  You, of course, cannot see
the System.out.println of an empty String, with or without a null
concatenated.

RE: Problem with using DynaValidatorForm, is it possible to do it??

[James Turner]

Your main problem is that simply naming the variable the same as the
form Bean name isn't going to create the correct instantiation of the
form.  You're basically creating a "vanilla" uninitialized
DynaValidatorForm and then trying to set it's properties, but it doesn't
have any.

The "official" way to instantiate a DynaForm bean in struts is to have
it be the input form for an action, which will cause it to be
automatically instantiated.  Sometimes this can mean chaining through an
extra action just to instantiate a new form bean, especially in the
cases where you are processing one form, and then prepopulating another.

RE: [OT] Date format

[Andrew Hill]

DateFormat is an abstract class of which SimpleDateFormat is a subclass.

When you call getDateInstance() what you get back is actually a
SimpleDateFormat - however I am under the distinct impression this depends
on the locale. Some locales could in theory give back something different
again or if the implementation of the factory methods changes in a future
JVM maybe it wouldnt use SimpleDateFormat?

You could do an instanceof to check if its a SimpleDateFormat and proceed
from there - of course for those locales that dont use SimpleDateFormat then
AFAIK you wont be able to get the pattern - this is because pattern is a
SimpleDateFormat feature and not a DateFormat thing so if it isnt a
SimpleDateFormat (or subclass of SimpleDateFormat) then there isnt a pattern
you can make use of anyway! (I could be wrong on that)

Out of curiosity I tried the following:
Locale[] locales = Locale.getAvailableLocales();
System.out.println("numLocales=" + locales.length);
for(int i=0; i < locales.length; i++)
{
  Locale locale = locales[i];
  DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, locale);
  String klass = df.getClass().getName();
  if(!("java.text.SimpleDateFormat".equals(klass)))
  {
System.out.println("class for locale" + locale + " is " +
df.getClass().getName() );
  }
}

It reported 145 available locales on my JVM. ALL of them used
SimpleDateFormat.
(But you cant rely on that - and in general its not considered good practice
to make assumptions about which implementation class you get back for a
factory method that returns a superclass or interface...)

Sorry I cant be of more help :-(

At the moment, it appears that the restriction that extension mapping must
be used for application modules will remain in the final release.  Two
things would be necessary to change this:

* Someone would have to come up with a strategy that resovles
  the problem of how to define path-mapped URLs that still
  include the module prefix in some reasonable fashion that can
  be parsed.

* Someone would have to implement this strategy.

For a non-module scenario, this is pretty much a cosmetics issue --
whichever style creates URLs that you like better is the one you should
use.

No, the FormBean can have request scope. How are you setting up the
form bean into the page initially? Are you sure you are setting it up
correctly in the struts-config.xml file? Maybe you could paste that
part of the code here.

I don't understand what you're asking, so I'll take a guess.  If you're looking for an 
escape senquence so that you can look for +'s and -'s  then try putting a \ in front 
of them, e.g., \+ and \-.

When I'm learning something new, I have always preferred to go "bottom
up".  For a prospective Struts developer, that probably means starting at
the appropriate point (for you) on the following list, depending on what
you're already familiar with:

* Fundamentals of object-oriented programming

* Java as a programming language

* Design patterns (at the programming level)

* Unit testing concepts and test-first design (JUnit is a wonderful
  tool for this in the Java space)

* Basics of relational databases, SQL, and the
  corresponding Java API (JDBC).

* Fundamentals of XML and XSLT (if you're going to be doing
  web services or XML-heavy applications)

* Architecture of the web (particularly how HTTP, HTML, and
  JavaScript work)

* The Servlet API -- foundation to every Java-based web application

* Basics of the view-layer technology (such as JSP) you plan to use
  If you're planning to use JSPs, plan on spending some time on:
  - Custom tags
  - JSTL 1.0 and the expression language

* Design patterns (at the architectural level)

* Implementations of the design patterns you plan to use
  (i.e. Struts as an implementation of the MVC design pattern)

* Use of advanced Struts features and extensions

The above list presumes you are going to be responsible for the entire
application.  In larger-scale environments there tend to be folks that
specialize on the various layers or tiers (persistent data storage,
business logic, presentation logic) -- if that is the place you are at,
you should spend more time on the technologies relevant to that specialty.

In all cases, there are an abundance of articles, tutorials, and books
around - the Struts resources pages include at least some starting points
for many of these areas.  To find more, "Google is your friend" :-).

Yes, that list is very long.  But the rewards for persevering and becoming
an expert are very great :-).

RE: java.lang.String question disguised as an ActionForm question

[Jarnot Voytek Contr AU HQ/SC]

"" + null ends up being "null" just as "" + 1 would end up as "1".  Remember
that Java will allow you to add anything to a String, it does the conversion
for you - that's why Object has a toString() method.

I am also very curious why one would ever need to write
String s1 = "" + null;

That's pretty curious; I would never have thought to do this, and wonder why
you are.  Anyway, it seems pretty obvious that s1 ==  + null
and s1 != null, so it fails the s1 == null test.  You, of course, cannot see
the System.out.println of an empty String, with or without a null
concatenated.

ok, though this problem came up dealing with ActionForms, I completely
understand that this is a fundamental Java question, nothing more, so I will
pose it as that only.  Also, I am prepared for taking some
thisQuestion(OrYou)DoesntDeserveToBeHere flak:

String s1 = "" + null;
System.out.println ("s1: " + s1);
if (s1 == null)
System.out.println ("s1 is null");
else
System.out.println ("s1 is not null");

produces output:
s1: null
s1 is not null

While if I replace the first line by, String s1 = "";
then it produces output:
s1:
s1 is not null

(which I have no problem with).

Question: Why does the 1st line of the output of the first case read s1:
null  ?

But by using an action path for input instead of a JSP, isn't the

JSP again? How do you redisplay the incorrect values the user typed into 
the JSP?

Axis/SOAP proposal for Struts

[Mike Oliver]

Struts Users, 

 

I would like to propose that Struts be extended to support another entry
point.  The ActionServlet would be augmented by an Axis/SOAP Web
Services Interface to Struts.  FormBeans would be part of the payload
for requests.  Responses would be generated by Forwards for SOAP.  This
new Axis entry point would do the same work as ActionServlet with the
only significant difference being the construction of the FormBean.
Incoming SOAP Requests would be configured to call the same
RequestHandlers and as far as the actions go they won't know that the
source was an HTML Form or a serialized FormBean.  

 

I feel this will give a great deal of flexibility to Applications where
they want a Web Browser User Interface as well as Web Services for the
same Application Data Model and Business Logic.

 

I am planning on doing this anyway, and felt it applicable to this group
and would offer to share it as a sub project and would welcome
contributions of thought, expertise and code.

DAO and Struts Best Practice

[Phase Web and Multimedia]

My struts app access my resource layer via a DAO pattern. I have been using
DAO for a while and have seen various manners in which this is implemented.
I have some questions for all of you out there in regards to the DAO pattern
that you use and why. Following are some comparison points between a few
patterns. What in your opinion are the pluses and minuses

Below I describe a few DAO patterns. If you have others feel free to append
them:

Static Method DAO Pattern:
- class is not instantiated
- class use static methods
- class contains multiple methods
- each method contains it's own connection instantiation and destruction
- parameters needed to perform each method's operation's are passed into the
method

Instantiated DAO with Method parameters: (* This is the pattern I use)
- class is instantiated
- class methods are NOT static
- class contains multiple methods
- connection is a setter/getter and is shared among all methods during the
life of the instantiated class object
- parameters needed to perform each method's operations are passed into the
method (no setters/getters)

Instantiated DAO Bean Pattern:
- class is instantiated
- class methods are NOT static
- class contains multiple methods
- connection is a setter/getter and is shared among all methods during the
life of the instantiated class object
- parameters needed to perform each method's operations are held on the
class level as members of the class. They are altered with setters/getters.
Each method receives no parameters.

The one method DAO:
This pattern can be applied to all of the above. Essentially every class
contains only one method that accomplishes a specific function.

I use the second pattern simply because during development I can see what
parameters my method needs to perform it's funtion and make sure they are
passed in. If I try to compile without providing the proper parameters the
compile fails and I know my error before I start testing the class. It's
simply a development things... easier javadoc and code completion as well.
But, there have been times when I questioned the amount of parameters being
passed into the method, but, rarely. My pattern does not easily lend itself
to using tools like BeanUtils to perform property copying from one bean to
another.

So, what are your thoughts.

Anyone know a good regular expression translator - or the equivalent of
allowing "+", "-" or " "?

Thanks,

There's no such thing.  You are thinking of the M$ VBScript debugger, which
comes with (at least) IE 6.0.  If you use Navigator, entering
"about:javascript" in the location field will return error messages.

Please, where can I download the Microsoft Javascript

RE: Indexed Properties and Population

[Raible, Matt]

Here's how I did it:

On my Form:

public ArrayList getKids() {
returns kids;
}

public void setKids(ArrayList kids) {
this.kids = kids;
}

public int getKidsSize() {
return kids.size();
}

In my JSP:


...

...



On my form (relevant for saving)

public void reset(ActionMapping mapping, HttpServletRequest request) {
// make the kids ArrayList the proper size and populate with
// empty objects
int kidsSize = Integer.parseInt(request.getParameter("kidsSize"));
kids = new ArrayList(kidsSize);
for (int i=0; i < kidsSize; i++) {
kids.add(new KidForm());
}
}

This seems to work great for me.  Any other suggestions/methods are
encouraged ;)  Is it lunchtime (beertime) yet?

HTH,

Matt

David says:
"One implementation that should work based on your example
as long as you are willing to create a child factory is in the commons
collection package and is ListUtils.lazyList, which takes a List and
factory."

I have used this as well, in combination with the nested tag library.
We have  a page that displays and updates a List of Value Objects where
each have two internal Lists of Value Objects.
The structure of value objects are sent to me from the back end as such:

CustomerList
  CustomerVo 1
creditVo1   invoiceVo1
creditVo2   invoiceVo2
.   .

  CustomerVo2
creditVo1   invoiceVo1
creditVo2   invoiceVo2
.   .


I would be curious to know  this would done without the nested tags and
lazy list.

Matt,

You really don't need to know how many there are, just create them
on demand. You can intercept gets and auto-extend the underlying
Collection. One implementation that should work based on your example
as long as you are willing to create a child factory is in the commons

collection package and is ListUtils.lazyList, which takes a List and
factory.

I have an ArrayList on a form... let's call the form Parent and the
ArrayList Children.

If I have:

private ArrayList children;

public void setChildren(int index, ChildForm childForm) {
 this.children.set(index, childForm);
}

Then saving my form results in a NPE for BeanUtils.copyProperties.  If
I
create a whole bunch of objects in the ArrayList in the constructor -
I
avoid this problem:

public ParentForm () {
children = new ArrayList(100);
for (int i=0; i < 100; i++) {
children.add(new ChildForm());
}

But I'm guessing that this fits better into the reset(mapping,
request)
method of my form.  My question is - how do I determine how many there
are?
Is there something in the request this this information - or should I
set a
hidden field with the number of children?

Thanks,

Matt

Hi guys,

I am trying to replace the Templates by Tiles ... 

The problem I am facing is, that the html:base tag is based on the
location of my layout-file. (in my case /layout ...) So all my images
now point to  ... /context/layouts/images/mg1.jpg, it should be
/context/images/img1.jpg ... 

Is there a solution for this  ?

thanks, Christoph

[Pani, Gourav]

The  tag also causes problems with links where you have to
implicitly specify the application root as part of your directory path in
your JSPs.

Re: Axis/SOAP proposal for Struts

[Joe Germuska]

I am planning on doing this anyway, and felt it applicable to this group
and would offer to share it as a sub project and would welcome
contributions of thought, expertise and code.


Craig has talked about a vision for Web Services being a part of 
Struts 2.x, although it doesn't seem to be on the "roadmap".

http://jakarta.apache.org/struts/status.html

I think a full release of 1.1 is the first priority, and then people 
seem ready to split into two streams.  But I suspect that Web 
Services properly belong in the 2.0 stream.

I'd be happy to hear why my suspicion is wrong...

Joe
