RE: RowSetDynaClass

[Rajat Pandit, Gurgaon]

just one more passing thought, I was wondering if there was some way to make
the SQL generic for all databases? (or is it not feasible). This seems to be
specific for oracle? Do correct me If I am wrong.

String q = "SELECT * FROM (SELECT ROWNUM ROWNO, Q.* "

try {
PreparedStatement ps = conn.prepareStatement(q);
ResultSet rs = ps.executeQuery();
rows = new RowSetDynaClass(rs,true);
rs.close();
ps.close();
}
catch(SQLException e) {
throw new PagedTableException(e.getMessage());

public Collection getRows() {

It was that simple :-)  And now anytime I need paging done, I simply store

I also got fancy and added a few helper methods to this PagedTableBean class
to give me quick access to the current page number, whether a prev/next page
exists, as well as a method called getSize() that issues a "SELECT COUNT(1)

This way, I can easily show something like:

  [<<] 100-150 of 7532 records [>>]

Let me know if you have any questions!

RE: Internationalization support in Tiles

[Suresh S]

Thanx joe , so its something like this i may be reusing a particular
layout again and again like the footer ,menu,.. etc but the original
body content may vary now instead of defining the html  tag in
each of the body pages is there any way we could do it from tiles (i
mean from tile-definitions.xml) by defining the key in the xml and to
later use bundle to extract the title .And also 



  
  
  
  


There is one more property in this
 so what is the use of this the 
book
says that

"There is an additional parameter, not shown, called definitions-factory-class. You 
can create a custom definitions factory and supply the class name here.
 The default is org.apache.struts.tiles.xmlDefinition.I18NfactorySet."

does it how anything to do with I18n ?


Thanks
Suresh S

RE: RowSetDynaClass

[Rajat Pandit, Gurgaon]

Hey Chris,
Thanks a lot for the detailed information. I have just one more issue, I
have used the RowSetDynaClass (beanutils.jar) and I had this issue where I
couldn't control the position of the column numbers as in the 2 column in
the sql could be anywhere in the resultset returned. I was passing the
collection object back to the display tag. Maybe it internally stores the
metadata information in a Map, or is it something wrong with my
understanding.
Do let me know if you have had any such issues before?
Regards
rajat

The PagedTableAction class I'm using don't do any client-side or JVM caching
because the data could change relatively quickly depending on the nature of
our business.  Thus, for us, letting the database handle the "subset" rownum
limits works well and is very efficient.  Right now I can return any subset
of data from a table that contains over 75000 records within < 2 seconds ..
And that's on pagesize ~ 100/150 or so.

Take care,

if that was really a problem for you, then there could any/both of 2

1. You never used ValueListHandler pattern.
2. You never had used any pager taglib.

and Chris, you could also look into *sql* JSTL that can help you doing

RE: Internationalization support in Tiles

[Joe Hertz]

Assuming you understand how Struts deals with internationalization
issues, and tiles here...

What sort of things are you looking to see demonstrated?

I'm doing just this, and I find that there isn't anything I really need
that is specific to tiles. Your tiles deal with the i18n issues as if
they weren't tiles at all. 

About the only concession I make to i18n with tiles is that I try to
avoid specifying string attributes in the tiles-config.xml.

String q = "SELECT * FROM (SELECT ROWNUM ROWNO, Q.* "

try {

RE: RowSetDynaClass

[Rajat Pandit, Gurgaon]

Hey navjot,
Thanks for the inputs(any pointers to the documentations (URL) would again
be of great help) I have been pretty happy using the display tag, for small
record sets (about 12000 or so) but I needed something more in case I needed
to customize the pagination stuff. Like caching stuff etc. 
Any pointers?
Rajat
(OT (only for navjot) ps: any clue where amit malhotra is these days?)

if that was really a problem for you, then there could any/both of 2 
reasons.

1. You never used ValueListHandler pattern.
2. You never had used any pager taglib.

and Chris, you could also look into *sql* JSTL that can help you doing 
what you want. And probabaly i recommend using this only for quick 
reports generation.

RE: session time out

[Rajat Pandit, Gurgaon]

Hello Lokanath,
I am not sure if this is the best way to go about it, but yes maybe you
could give it a shot, in the action where you are checking for the session
object (could be a login bean or something) make sure that you throw a
custom exception and using the global exception handler in the
struts-config.xml you can use GlobalForward to forward it to a particular
page, say a login page or something.
Do tell me if this worked out for you, because I might have to implement it
at a later stage, I am currently documenting the specs for my project.
Regards
rajat

Hi,
same thing i have experienced with IE 6.0, it will work with mozilla
Problem is that with each request session id is not passed.
You need to explicitly pass it as url parameter.

1. I installed the application on a machine having the IP

2. Now when i access the application using http://10.1.252.41/ or

3. When i use the "http://dbomis.com/"; then the login page come. User
is able to login (processPreprocess() method does not check for
session while user is logging in). But when the user clicks on any
link the session becomes null so the user is logged out of the
application. This problem happens only on I.E. update version SP1.
On I.E 5.5 this url works ok.

Anyone has got any idea why this must be happening

Re: Strange error message

[Shailender Jain]

I think you are using some code
after response.sendRedirect() or doForward() which forward the request to other
page.
The best practice will be to use a return statement after doing the forward.
You should ensure to complete all you business logic before these statements are
used.

Yes, this happens when you have already sent the headers to the client and

RE: Cannot Find Bean in Any Scope

[Caroline Jen]

I am following your suggestion.  I put my "while" loop
in the  tag, and I have changed 

<%=threadBean.getSender()%>
to 


There is a situation which I do not know how to
handle.
Inside the  tag, I have a line of
code:

<%=SiteUtil.filter( threadBean.getPostTopic(),
false/*html*/, true/*emotion*/, false/*mvnCode*/,
false/*newLine*/, false/*URL*/ )%>

This JSP expression calls a method 'filter' in another
class SiteUtil.java.  And one of the properties
(postTopic) of the threadBean is passed as a parameter
to that method.  

How do I use the  tag in the above JSP
expression?

Thank you in advance.

RowSetDynaClass

[CRANFORD, CHRIS]

I am storing a RowSetDynaClass property in my java class and I have
implemented a method on my class as follows:

public Collection getRows() {
  return((Collection)rsdc.getRows());
}

In my action, I store my custom class object reference as follows:
  request.setAttribute("results", myResultsObj);

Then in my jsp, I do the following:
  
  
.  -

  

I get the following error:
[ServletException in:/pages/test-body.jsp]
An error occurred while evaluating custom action attribute "value" with
value "${row.item_id}":
Unable to find a value for "item_id" in object of class
"org.apache.commons.beanutils.BasicDynaBean" using operator "." (null)

Can someone tell me what I am doing wrong here and how I can do this
properly to get it to work?

Re: [OT]Help needed in wring regular expression

[Navjot Singh]

but you can achieve your objective in 2 easy regex.
Anyway can you try something like this
(\d(1)[^0])|(\d(1)\d(1)[0-9]{1,3})|(FEW)|(few)|(MANY)|(many)

first non-zero integer and totally 4 digit maximum. 

I tried using "(\d(1)?[1-9]{1,4})|(FEW)|(few)|(MANY)|(many)" to avoid
entering 0 as first value but it fails if we enter "00","000""" + I
could not restrict the size to be 4 digit max when I tried to enter more

Can anybody help me to write regular expression for the above conditions or
any sample example code for the above case or any suggestions.

RE: Cannot Find Bean in Any Scope

[Caroline Jen]

I am following your suggestion.  I put my "while" loop
in the  tag, and I have changed 

<%=threadBean.getSender()%>
to 


There is a situation which I do not know how to
handle.
Inside the  tag, I have a line of
code:

<%=SiteUtil.filter( threadBean.getPostTopic(),
false/*html*/, true/*emotion*/, false/*mvnCode*/,
false/*newLine*/, false/*URL*/ )%>

This JSP expression calls a method 'filter' in another
class SiteUtil.java.  And one of the properties
(postTopic) of the threadBean is passed as a parameter
to that method.  

How do I use the  tag in the above JSP
expression?

Thank you in advance.

Trust me this isn't an attempt to open up a whole flame war. I'm just 
curious how many of you have messed with Spring and what your thoughts 
concerning it are.

I've been looking at it some and I do see some strengths it has, but some 
of those strengths I also see as potential weaknesses (maybe).

In my short study (and I mean very short:) of Spring, here's what I've been 
thinking so far...

(Note, Spring handles a lot more than the just the front end framework, but 
since Struts is mostly a front end framework these comments about Spring 
are in relation to the web component portion of Spring).

Flexibility. Here is where I think Spring's major strength lies. You are 
given some out-of-the-box controllers and stuff but how the application is 
put together with the framework allows for a lot of flexibility. In a large 
corporation, though, this all could be a weakness if one isn't careful. It 
seems very easy to have part of an application being coded using entirely 
different Spring concepts than another part. Struts has this problem as 
well, although it appears more difficult to abuse since, unless you start 
really doing funky things in Action execute methods (seen it done), it's 
pretty easy to stay within 'best practices' guidelines.

Learning curve. I can't really tell which is an easier framework to pick up 
and learn. I've been working with Struts for a long time now, so it's 
difficult for me to look at this objectively. The fact that there are a lot 
more ways of developing web applications with Spring can be somewhat of an 
obstacle for picking it up quickly.

View tags. I happen to like the basic struts html tags related to forms. 
Spring doesn't come with much of a tag library that I can tell. I'm not 
sure how tags such as the Nested tag will play with Spring. Currently you 
have to provide all form field values with JSTL... not a big deal except a 
bit unwieldy for nested beans (imo).

Lack of ActionForms. Spring doesn't use ActionForms and I like this. You 
can tie a Value Object right to your front end form. Very nice.  If Struts 
got away from ActionForms I'd be very happy (although I'd lose some of the 
nice html tags functionality).

Spring also uses a lot of cool stuff like IoC (Inversion of 
Control/Dependency Injection).

Right now, as it stands, I'm finding it difficult to justify switching over 
to 'yet another framework' (Sheesh how many are there now - Spring, 
WebWorks..:). I've run into some limitations using Struts (such as its nice 
handling of a 'form wizard flow' where you might need to action chain - 
gets a bit ugly) but overall I don't really have many complaints about 
Struts. It appears that I'm not going to gain that much switching over to 
Spring. A lot of my good buddies in #FunkyCodeMonkey on darkmyst.org are 
former Struts users and they seem to like Spring better - although, they 
haven't given me enough compelling reasons to jump ship.

I've only begun to start looking into Spring so I'm sure I'm missing a TON 
of points that could be made

A couple tiles questions. 

1.) Is there any way to have a global-forward forward to a tile, It always

Hmm not sure what is wrong. You could try adding contextRelative="true" 
to the global forward. We have some global forwards that look like:



2.) I am using the same forms for editing and creating new entity instances.
These happen in different tiles, I want to have my local action forward to
the tile which called the action in the case of success or failure. Is this
possible (struts 1.1) 
I'm not exactly sure what you are asking, but if you set up two tiles 
definitions, I'm not sure how there would be a problem. I might be 
missing where the problem is.

3.) How can I do a context switch from within action code to forward to a
different context (preferably without writing extra action elements in my
struts-admin.xml config file) 
Not sure about that.
Side note... using SiteMesh instead of tiles will make all of this 
easier. You won't have to make a bunch of tile defiitions, you simple 
forward to jsps. Based on the url pattern (or other ways) you then have 
the page decorated for you. I threw up a simple example here

I used the stuff from jpowered.com and it works pretty well.  I am not
to the point yet where I have the licensed version yet, but the demo I
got a week or two ago is working out pretty well with my Struts app.

RE: security roles

[Zhang, Larry \(L.\)]

Thanks Pedro. 

I am not using Tomcat, instead I am using IBM WSAD , so if I define the following 
lines in web.xml, 


A normal employee user
Employee


a manager user can do PR
Manager


can I access Employee and/or Manager role in struts-config.xml?

(2)also say a manager logon our sites, I can obtain the info for this user such as 
"managerFlag", and then where should I put the logic to decide whether the user is a 
manager or an employee, and how to map this user to a security-role defined above?

  In struts-config.xml, define the actions this way:


Only manager can execute the action



Only employee can execute the action



Manager or employee can execute the action




Everyone can execute the action




You can define the roles on your TOMCAT_HOME/conf/tomcat-users.xml (for
Tomcat 4.1.30).

I want to define two security roles, one of which is employee and another is
manager. Employee is not able to see some resources belonging to manager.
Under J2EE standard, we can define these in web.xml, it also seems to me
that this can be done in struts.

Can you point out how to perform this task? Detailed instruction is
appreciated.

RE: [OT] A first look at Spring vs Struts

[Ricardo Cortes]

The best application framework I've used for developing web applications has to be 
WebObjects (http://webobjects.com), hands down.  Although the cost is $700, you get 
what Struts, Tiles, Hibernate, JSP and servlets try so hard to emulate except that 
it's all bundled in one package.  So integration between database modeling and 
front-end display is seemless.  Also, the persistence layer, in my opinion, is miles 
ahead of anything out there, including Hibernate and JDO (notice I didn't even mention 
EJBs).  With that said, the WebObjects market has indeed gone downhill and the 
specifications behind J2EE have somehow made proprietary software less of an option 
than they were 5 years ago but it's still the best application framework I've ever 
used.

Now, with respect to the thread at hand, we are currently using both Spring and 
Struts.  Struts and Tiles are used on the front end and Hibernate and Spring are used 
on the backend.  The integration Spring has for Hibernate out of the box makes things 
a heck of a lot easier.  I don't see our platform transitioning to a 100% pure Spring 
implementation but I also don't see us ever taking Spring out of the equation.  So, 
all in all, they both can be used side by side and not just as a replacement for the 
other.

Ciao,
Ricardo

Subject: [OT] A first look at Spring vs Struts


Trust me this isn't an attempt to open up a whole flame war. I'm just 
curious how many of you have messed with Spring and what your thoughts 
concerning it are.

I've been looking at it some and I do see some strengths it has, but 
some of those strengths I also see as potential weaknesses (maybe).

In my short study (and I mean very short:) of Spring, here's what I've 
been thinking so far...

(Note, Spring handles a lot more than the just the front end framework, 
but since Struts is mostly a front end framework these comments about 
Spring are in relation to the web component portion of Spring).

Flexibility. Here is where I think Spring's major strength lies. You are 
given some out-of-the-box controllers and stuff but how the application 
is put together with the framework allows for a lot of flexibility. In a 
large corporation, though, this all could be a weakness if one isn't 
careful. It seems very easy to have part of an application being coded 
using entirely different Spring concepts than another part. Struts has 
this problem as well, although it appears more difficult to abuse since, 
unless you start really doing funky things in Action execute methods 
(seen it done), it's pretty easy to stay within 'best practices' guidelines.

Learning curve. I can't really tell which is an easier framework to pick 
up and learn. I've been working with Struts for a long time now, so it's 
difficult for me to look at this objectively. The fact that there are a 
lot more ways of developing web applications with Spring can be somewhat 
of an obstacle for picking it up quickly.

View tags. I happen to like the basic struts html tags related to forms. 
Spring doesn't come with much of a tag library that I can tell. I'm not 
sure how tags such as the Nested tag will play with Spring. Currently 
you have to provide all form field values with JSTL... not a big deal 
except a bit unwieldy for nested beans (imo).

Lack of ActionForms. Spring doesn't use ActionForms and I like this. You 
can tie a Value Object right to your front end form. Very nice.  If 
Struts got away from ActionForms I'd be very happy (although I'd lose 
some of the nice html tags functionality).

Spring also uses a lot of cool stuff like IoC (Inversion of 
Control/Dependency Injection).

Right now, as it stands, I'm finding it difficult to justify switching 
over to 'yet another framework' (Sheesh how many are there now - Spring, 
WebWorks..:). I've run into some limitations using Struts (such as its 
nice handling of a 'form wizard flow' where you might need to action 
chain - gets a bit ugly) but overall I don't really have many complaints 
about Struts. It appears that I'm not going to gain that much switching 
over to Spring. A lot of my good buddies in #FunkyCodeMonkey on 
darkmyst.org are former Struts users and they seem to like Spring better 
- although, they haven't given me enough compelling reasons to jump ship.

I've only begun to start looking into Spring so I'm sure I'm missing a 
TON of points that could be made. I'd appreciate any other comments good 
or bad concerning either framework. I'm sure many of you fall into the 
same frustration-boat that I feel like I'm in- "So many technologies out 
there - only so much time." I've trying to determine if I really need to 
be investing the time to explore this framework more when I could be 
exploring other things I need to learn more about. I'm sure many of you 
can relate:)

[OT]Help needed in wring regular expression

[RDoss]

Hi,
Web page contains a text box can accept only maximum of four digits and it
can be integers/String(accepts only "many","MANY") if enter a single integer
value it should not be 0(zero) and 0(zero) can be entered subsequently after
first non-zero integer and totally 4 digit maximum. 

I tried using "(\d(1)?[1-9]{1,4})|(FEW)|(few)|(MANY)|(many)" to avoid
entering 0 as first value but it fails if we enter "00","000""" + I
could not restrict the size to be 4 digit max when I tried to enter more
than a digit.

Can anybody help me to write regular expression for the above conditions or
any sample example code for the above case or any suggestions.

Thanks in advance.

Re: security roles

[Pedro Salgado]

  In struts-config.xml, define the actions this way:


Only manager can execute the action



Only employee can execute the action



Manager or employee can execute the action




Everyone can execute the action




You can define the roles on your TOMCAT_HOME/conf/tomcat-users.xml (for
Tomcat 4.1.30).

It's not obvious from your email, but
did you:
1) Check for conflicting servers i.e.
telnet www.michaelmcgrady.com 6082
2) Check that /127.0.0.1 is a valid
interface for [your] machine.

Re: Struts/Lunar Pages/Resin

That makes sense, James, except my site is not using
or accessing struts at 
this time.  That site is only using a single page which merely accesses
the 
request object's remoteAddr parameter.So, my product could not be the 
issue.  Did you read the stderr log?  My suspicion is that the
server 
administrator at Lunar Pages is OTL.  But, I thought I would ask here

first.  It seems clear from the stderr log below that my site details
could 
not be causing the trouble.

Re[2]: Caching data from resultset

[Andrey Rogov]

You can try the following. If there are no data in the cache you can
select
 SQL :
SELECT *.blah...,
rownum
 FROM (
  SELECT *.blah...
FROM portal.dbtables dbt
   WHERE 
   ORDER BY dbt.datemessage desc
  )
 WHERE ( rownum between #firstrow# and #lastrow# )

   Oracle 9i will do it fast. It has cache of its own. Appropriate lines
   will be picked out of the table. Then you save  bean collection in session scope
   or application scope. Then, if more pages are picked out you can
   find, if there are data in the cache - then show,  if not, add etc. I apply both
   Oracle rownum and a small cache for dynamic data if data update is not so frequent.

   Best regards,

   Andrey.

Re: Struts/Lunar Pages/Resin Issues

[mike]

That makes sense, James, except my site is not using or accessing struts at 
this time.  That site is only using a single page which merely accesses the 
request object's remoteAddr parameter.So, my product could not be the 
issue.  Did you read the stderr log?  My suspicion is that the server 
administrator at Lunar Pages is OTL.  But, I thought I would ask here 
first.  It seems clear from the stderr log below that my site details could 
not be causing the trouble.

Re: images

[mike]

There are lots of ways to do this.  You can use the File class to see if a 
file exists (images are files, of course) and go from there in a million 
directions.

Simple struts question.

[Bullard, James]

A couple tiles questions. 

1.) Is there any way to have a global-forward forward to a tile, It always
tells me that such a path does not exist, meaning that rather than recognize
the page as tile def it thinks it is a page. 

2.) I am using the same forms for editing and creating new entity instances.
These happen in different tiles, I want to have my local action forward to
the tile which called the action in the case of success or failure. Is this
possible (struts 1.1) 

3.) How can I do a context switch from within action code to forward to a
different context (preferably without writing extra action elements in my
struts-admin.xml config file) 

Thanks in advance , j

Lunar Pages suspension due to Resin difficulty with Struts

[mike]

For unknown reasons lunarpages suspended my account, saying that my struts 
application was causing the server to restart by having the initialization 
procedure tied to the message resources to try and bind to 
127.0.0.1:6802.  Does this make any sense to anyone?  I think someone at 
lunarpages screwed up.  Nothing had changed on my site for at least a 
month.  Then, suddenly they had this problem.  Does this make any sense to 
any of you?

Accessing Array element while iterating through Map

[Geoff Simonds]

I am trying to iterate through a Map and use the key from the map to 
access an element in a separate array.   I have an array of data points 
and only want to display the entries that are specified in a separate Map. 
 Here is a snippet:






The Map contains data that looks like this:
"1", "1 yr"
"2", "2 yr"
"5", "5 yr" 
etc...

Whe the page is rendered, it draws a bit of the page and the remainder of 
the page remains blank.  I can't find any log entry to indicate that any 
errors are being thrown.  If I print out the results of <%= 
"annualizedReturns[" + year + "].performance" %> between , I get the 
correct value ( ie, annualizedReturns[1].performance) and when I replace 
the property attribute in the bean:write tag above with 
"annualizedReturns[1].performance" hardcoded, it works fine.  What am I 
doing wrong? 

Thanks for any help.

Approach for using view Action and save action

[Jyoti Singh]

I am working on an application where I read combo
boxes option values from database based on certain
fields values. I do not want to store the option
values in the session. Currently I forward to view
action after saving the form data. View action always
reads data from database for populating actionform
values and the option List values. In normal case
everything works fine. But if save can not be done
because of some data validation errors, I set an
attribute "doNotReadFromDatabse"in request scope in
save action and I check  that attribute in view
action. If it present, I do not modify the form
values. I just read the combo box list values and put
in the request scope.

Is it a good approach? 
Thank you very much,
Jyoti

how to transfer the link value of tiles to the related-URI in html:link tag...

[Ricky Lee]

thanks for reading
 
i know the html tag of struts a little..and in the html:link tag, i can use the page 
attribute to generate a server-relative URI by including the context path... but now i 
have a problem. i couldn't nested a  inside another tag. just like:
 


" target="main">

 
because the link property is from the tiles definition named tiles-defs.xml, some 
definition code like this:
 

 
 
   

 

 
the URL address i access to the jsp page is   http://localhost:8080/forum/index.jsp
 
if i set the link value to "/page/admin/forumAdd.do", the hyperlink change to 
http://localhost:8080/page/admin/forumAdd.do  ,   it lost the path "/forum"..
 
how to transfer the link value to the related-URI automatically just like the page 
attribute of html:link tag..
 
could i use the code like this?
 
" target="main">

 
i try it.. i couldn't work... maybe i lost something important about struts tag..
 
lastly, i change the code like this:
 
 




 
could someone tell me what can i do except this

RE: Caching data from resultset

[Kies, Daniel]

Here is where the inline views are needed.

Try it like this:

select * 
  from ( select rownum r, --add your other records
   from (SELECT * 
 FROM some_table)) WHERE r between 11 and 20

I can't remeber why you can't use:
WHERE ROWNUM BETWEEN 11 AND 20

It has something to do with rownum being a sequential number coming back
from the resultset.  That's why you need the inline views to order your
resultset properly.  

Here is a real query that I am running:

select * 
from ( select rownum r, 
 INSURED_NAME, 
 POLICY_NUMBER,
 POLICY_EFFECTIVE_DATE,
 WRITTEN_PREMIUM_W_PC, 
 EARNED_PREMIUM_W_PC, 
 TOTAL_LOSSES_INCURRED, 
 INCURRED_LOSS_RATIO*100, 
 commission_expense 
   from (select trim(t.INSURED_NAME) INSURED_NAME, 
t.POLICY_NUMBER,
  t.POLICY_EFFECTIVE_DATE,
t.WRITTEN_PREMIUM_W_PC, 
t.EARNED_PREMIUM_W_PC, 
t.TOTAL_LOSSES_INCURRED, 
  t.INCURRED_LOSS_RATIO, 
t.commission_expense 
 from some_insurance_table t 
  where t.ACCIDENT_YEAR = '2003'
order by trim(t.INSURED_NAME) ASC,
t.POLICY_EFFECTIVE_DATE desc )) 
WHERE r between 11 and 20

If you still have problems getting your query running, send it to me
directly and I'll see if can't get it going.

I recently implemented pagination for resultsets using Oracle 9i.  Instead
of loading up the entire resultset into memory, I just queried based on the
records that the user requested.  

1) Before getting the records, I first counted the records that were coming
back in the result.  That way I can say to the user...showing results 26-50
of 2,183.  
2) For the first resultest, I would run my query appended with a "rownum
between 1 and 25" 
3) If the user paginates, then I throw the pagination numbers into the query
so the query would be appended with "rownum between x and y"

This is a pretty simple solution to pagination with Oracle.  You may have
some issues getting your resultset ordered properly coming from Oracle, but
using inline views should take care of that.

The advantage to doing this is scaleability.  I am running this code on top
of a Data Warehouse where every milisecond counts.  Using rownum for the
resultset off the database limits query execution time and allows for
resultsets of any size.  Using resultsets with a rownum will allow Oracle to
cache the SQL you are using to execute quicker.

Let Oracle do the work.

Not sure how much this is going to help because we're averaging about 15
seconds to transform a resultset of 1200 records into dynabeans.  My goal
really is to be able to dynamically traverse only the needed records within
my resultset.
 
So, when my resultset gets returned and I forward to page 1 (assuming we
show 10 hits per page), I would fetch rows 1-10 and cache their data.  Then
when the user hits page 2, I would fetch 10 more rows from the resultset and
append records 11-20 in the cache.  So at this point, records 1-20 are
cached and my resultset it pointing to record 21.
 
Now, if the user hits the previous page button, my application would move
the offset back to current offset - viewable count (11-10=1) and it would
pull records 1-10 from the cache.  This avoids calling the database for
data.  Then hitting next page would check and see that the resultset pointer
is at 21 but offset < resultset offset, so assumes cache.  It pulls records
11-20 from the cache list again without a call to the database.
 
Is this what I am looking for and didn't know if a package already existed
to do this.  If so, great.  If not, I need to invest some time in developing
one for a project due tomorrow afternoon :-)

RE: Caching data from resultset






Not a problem because I do have an OTN account.  But I guess the question is
whether it will work with Oracle 8i or only 9?

In the past what I have done is used introspection to convert the resultset
via metadata into a collection of objects that represent a record in the
database and use this "collection" in the JSP layer.  I typically notice
that this is where the MAJORITY of my time is consumed creating these
objects in memory, especially on very large data sets.

Ideally I want to create a business wrapper than extends some form of
caching resultset mechanism that permits me to save already viewed rows in
memory and only "fetch" ahead rows from the resultset as the user jumps to
the next page.  Since oracle 8i only provides forward scrolling in the
resultset, its important that previously viewed records be cached in the
bean.

Would all this be functionality available using CachedResultSet (ocrs12.zip
from oracle) via 8i database and jdk1.2?

RE: Caching data from resultset

[Kies, Daniel]

I recently implemented pagination for resultsets using Oracle 9i.  Instead
of loading up the entire resultset into memory, I just queried based on the
records that the user requested.  

1) Before getting the records, I first counted the records that were coming
back in the result.  That way I can say to the user...showing results 26-50
of 2,183.  
2) For the first resultest, I would run my query appended with a "rownum
between 1 and 25" 
3) If the user paginates, then I throw the pagination numbers into the query
so the query would be appended with "rownum between x and y"

This is a pretty simple solution to pagination with Oracle.  You may have
some issues getting your resultset ordered properly coming from Oracle, but
using inline views should take care of that.

The advantage to doing this is scaleability.  I am running this code on top
of a Data Warehouse where every milisecond counts.  Using rownum for the
resultset off the database limits query execution time and allows for
resultsets of any size.  Using resultsets with a rownum will allow Oracle to
cache the SQL you are using to execute quicker.

Let Oracle do the work.

Not sure how much this is going to help because we're averaging about 15
seconds to transform a resultset of 1200 records into dynabeans.  My goal
really is to be able to dynamically traverse only the needed records within
my resultset.
 
So, when my resultset gets returned and I forward to page 1 (assuming we
show 10 hits per page), I would fetch rows 1-10 and cache their data.  Then
when the user hits page 2, I would fetch 10 more rows from the resultset and
append records 11-20 in the cache.  So at this point, records 1-20 are
cached and my resultset it pointing to record 21.
 
Now, if the user hits the previous page button, my application would move
the offset back to current offset - viewable count (11-10=1) and it would
pull records 1-10 from the cache.  This avoids calling the database for
data.  Then hitting next page would check and see that the resultset pointer
is at 21 but offset < resultset offset, so assumes cache.  It pulls records
11-20 from the cache list again without a call to the database.
 
Is this what I am looking for and didn't know if a package already existed
to do this.  If so, great.  If not, I need to invest some time in developing
one for a project due tomorrow afternoon :-)

I also failed to mention that a database connection is unqiue for each user
session and is persisted at the session-layer.  Not sure if that makes a
difference in how to best do what I'm after but I felt it was important
mentioning is its how the user/security model was originally designed.

Indexed Property with checkbox

[Davide Gurgone]

Hi all,
I'm new of this newsgroup and I tried to find about the subject, but I don't
succeed :( ...

however... I have a bean that extends ActionForm with also this R/W property

  private String[] esami;
  public String getEsami(int index) {
return esami[index];
  }
  public void setEsami(int index, String value) {
esami[index] = value;
  }

In the JSP I have in session *another* object called "esami" that contains a
list of checkboxes:

  
  
]" 
   value=""
   id=""/>

  

this code whant to replicate the  tag, with the indexed property.
I whanna do this thing because the value of the  could not insert
a runtime value on it (e.COD_RISULT).

In this way the code does not run and raise a BeanUtils.populate exception.
I think I wrong the way, But I don't know what can do...

I hope I'll not create a flame,

best reguards,

RE: Different input formats

[Robert Taylor]

Use Strings as data memebers in your action form when ever possible.
You can "translate" the input in the action class performing what ever
logic is necessary.

Actually, it looks like this is only
available for Oracle 9 or greater.  Sorry about that.  You might
have to go with the standalone rowset.jar.

Hi Leon,

I suppose that, since you're talking about caching the ResultSet, you've
already given a thought to the amount of data that you'd be handling,
consider it to be feasible and reasonable to cache it.

This said, why don't you take a look at CachedRowSet?

http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/rowset/CachedRowSet.html

Different input formats

[Renato Romano]

I have an  input in my form, in which the user should put a
float value. Now I would like to allow the user to enter the Italian
decimal separator, that is comma (",") instead of dot ("."), but of
course I got a null property value for the Float in my ActionForm!! I
then tried to do this by myself, and it works fine, but I have to
directly access request.getParameter("...") which is undesirable, also
because now I have a form in which the former is nested, and so
request.getParameter("...") should take this into account.

Is there a better and "standard" solution to this ?
Thanks everyone

I was using rowset.jar before I started JDK 1.4. I think you could download
it from the internet. Not sure if it works on your case.

Let me know if you need me to send you this package.

RE: Help with Datavision + Struts

[Frank Zammetti]

I'm using Datavision in a Struts-based application.  I'm not sure about 
passing an entire where clause, I've never tried that, but you can easily 
pass parameters to the report, which obviously you can use in your where 
clause.  Here's some code for doing that:

Report report = new Report();
report.parametersSetManually(true);
Parameter p = report.findParameterByName("myParameterName");
p.setValue(0, "myValue");
If you truly have to set arbitrary where clauses, that probably won't help.  
One thing you might be able to do is read in the XML of the report, then 
just modify the  element of the  element.  You could parse if 
as XML, but what might be easier, since you need to read it into a String 
anyway to hand off the the Report object, is just locate  and 
 in your String, copy from the start of the string until the end of 
 to a StringBuffer, then append the query your user entered, then 
append the remainder of the original String from the beginning of  
to the end.  A little more work, but nothing mind-shattering.

This is a Query class that takes as a constructor parameter a Report 
object... I'm not sure if that is any help, but it does have a 
setWhereClause method... the question is whether it sets it in the Report 
you pass in, and I don't know the answer.  Even if it doesn't, it does have 
a writeXML method that writes out the full  tag, and maybe that will 
be helpful to you.

If none of this is any help, I suggest hoping on the Datavision mailing 
list.  Jim, the author, has bee helpful to me in the past, I'm sure he'll 
answer your question promptly.

Subject: Help with Datavision + Struts
Date: Mon, 14 Jun 2004 09:20:16 +0200
Hi. We are de developing an application using struts. In this application
we have to develop reports (of course) and we decided to use Datavision. We
want to use datavision in our action classes. We have one problem and we
don't know how to solve it. The problem is:
The user has a form in wich he or she enters some criteria to select the
records to be listed. ?Can I pass the WHERE  clause to datavision as a
parameter? Something like this: ID > 100 AND ID < 500 AND NAME LIKE
'PETER%'. If I can, do you have any example.
	Does anyone have  experience with other reporting tool?, is there any 
other
tool better than datavision?

Thanks in advance.

[ANN] Xkins 0.9.8 Released (includes Struts and Xkins POC)

[Guillermo Meyer]

A new version of Xkins (http://xkins.sourceforge.net/) has been
released.
This new version has some new features including the capability of
compose new Skins based on existing ones.

Xkins is a framework to mannage Skins for web applications.

You can download the last version from:

http://sourceforge.net/project/showfiles.php?group_id=83923&package_id=8
6521&release_id=245465

There is also a Proof of Concept of Xkins using Struts. This demo will
show how Struts and Xkins can be combined to add Skinning capabilities
to Struts web applications.

The full list of features is:
New functionality: 
1) Skin composite: allows to compose a skin with templates from other
skins, in a composite fashion. 
2) Proof of Concept Xkins application: uses Xkins in a Struts based web
application. Allows to create a Custom Skin by the user. 
3) XkinsEditor: a new class that allows to compose Skins. see example in
skinAction in Xkins POC 
4) Log4J: XkinsLogger is created. Uses this logging mechanism inside
Xkins. XKINS category is created. 
5) JByte: New Template processor that uses Java By Template.
 
Changes: 
1) Add release() method to taglibs. 
2) API improvement: Allows to use xkinProcessor and create templates on
the fly easily: 
a) Add a constructos for Skin with name, and with name and
processor. 
b) Add a constructor for Processor that receives a class as the
TemplateProcessor 
c) Add a constructor for Content to receive a string with the
content or the url where the template content is. 
d) Add a contructor for Template to receive a string with the
content or the url where the template content is, and with name and
processor. 
3) Upgrade to Velocity 1.4 
4) Bug correction on reloading Velocity based templates: When a Velocity
template was modified and Xkins were reloaded, templates remained
cached. This is solved in this version. 
5) XkinProcessor and an undefined skin: if you create a XkinProcessor
with an undefined skin name, the default skin name is used. 
6) Add a SkinType getter to Xkins 

Cheers.
Guillermo.

I am using the Struts framework.  I have a JSP, which
imports a JavaBean "ThreadBean".  Therefore, in the

<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

I have

<%@ page import="org.MyOrg.MyProj.message.ThreadBean"

In my JSP, I try to write out the properties of this
JavaBean; for example:

  <%=threadBean.getSender()%>
  <%=threadBean.getThreadReplyCount()%>
  <%=threadBean.getThreadViewCount()%>

I got the error message:

- Root Cause -
javax.servlet.ServletException: Cannot find bean
threadBean in any scope

What is the correct way to do it?

Hi Leon,

I suppose that, since you're talking about caching the ResultSet, you've already given

reasonable to cache it.

This said, why don't you take a look at CachedRowSet?

R: Caching data from resultset

[Amleto Di Salle]

Hi,
you can use the Value List Handler design pattern.
See http://www.corej2eepatterns.com/Patterns2ndEd/ValueListHandler.htm
for an overview.

See http://www.theserverside.com/patterns/thread.tss?thread_id=26139 for
an implementation. I never used it but it is seems very good.

If you will use it please give us some feedback!

RE: Struts scalability and benchmarking

[Jesse Alexander (KXT)]

If you are not sure whether you will end up with 100 or 100'000 users...

Well, I would try do design the system with "clustering" in my mind.
Then I could throw more hardware at it, without too much problems. Seems
that even Tomcat 5 is capable of clustering nowadays, so  it should not
even be a problem of money.

"Clustering in my mind": If its just for scalability, then try to avoid
applicaiton-wide caches. If its also for fail-over: then you have to watch 
your session size.

What if the system needed to scale to thousands (or potentially even
millions) of user? Would just throwing more hardware solve the
scalability issues? I know this sounds really open ended, but I'm just
trying to figure out how well struts has performed (or will) in the past
for large websites. The FAQ seems to have the "struts powered website"
link missing.

Personally, I think this would be more a function of
(1) the application server/container that you are using
(Tomcat/JBoss/WAS/...) and

(2) the hardware/clustering etc.

Also, you need to do some additional analysis on expected number of
users, estimate how much data will be held in the session, what database
you are using, blah blah

RE: Help with validate ActionForm method

Hi Satish,

Problem is not related to validate="true" set on two actions, I've only one
in my whole struts-confif.xml file.

Any other idea?

I hope you have not set validate="true" for the both the load and submit
action mapping
i.e there wld be a action mapping for loading the screen(say load) The
validate attribute for this action
Be set to false

Then there wld be a action maqpping when to want to validate(say on submit
of a button - lets call it submitaction). The validate attribute of only
this shld be set to true

Hi,

I'm using ActionForm for one of my pages and I implemented the validate
method as follow: public ActionErrors validate(ActionMapping mapping,
   HttpServletRequest request) {
ActionErrors errors = new ActionErrors();

if (isFieldEmpty(login)) {
  errors.add("login", new ActionError("loginForm.login.required"));
}

if (isFieldEmpty(password)) {
  errors.add("password", new
ActionError("loginForm.password.required"));
}

if (errors.isEmpty()) {
  if (!isConnected(login, password)) {
errors.add("login", new
ActionError("loginForm.msgs.wrongLoginorPassword"));
  }
}

if (!errors.isEmpty()) {
  getLogger().info(this, "Failed attempt to log in : [" + login + "/" +
password + "] from : " + request.getRemoteHost());
}
return (errors);
 }

You can see that I log each time someone fail to log in.
When the validate method returns an empty Error Array, login/password are
checked in an Action object.

The problem is that I have the following trace in the log when somebody
successfully log in : 09:26:54,500 INFO  [lex.LoginAction] User logged in
[login/pwd] sessionId [773BB4634682A159DC680847073E4EC8] from [10.10.10.10]
09:26:54,587 INFO  [lex.LoginActionForm] Failed attempt to log in : [/] from
: 10.10.10.10

These traces obiviously means that the validate method is called twice, the
second time the ActionForm having empty fields.

Does anybody know why such a thing would happen 

Thanks

Caching data from resultset

[CRANFORD, CHRIS]

I am working with Oracle 8i and JDBC and was curious how others have
implemented paging through large record resultsets from a JSP application
without making a SQL call from page to page to retreive the data and looping
through records to place the cursor at the right offset in the resultset.

What I would prefer to do is make the database call once and cache the
resultset object and as the user navigates forward, fetch row-by-row of only
those required for the display.  Then if the user navigates backward, those
records are in a cache inside this bean so the cache is referenced for the
data (due to the fact Oracle's resultset is forward step only).  

Is anyone familiar or done anything like this in the past?

RE: Chaining dispatchactions problem, how to do it cleanly

[Cosyns Xavier]

>I've used a similar approach but mine is working fine.
>what does your struts-config.xml look like?

Hi, 
Here is my struts-config, ShowAttributesList.do is my preaction before
displayin the list of objects, then we select one of the list and
execute the gocreateattribute action, and lastly we have the
CreateAttribute action which will reforward to the ShowAttributesList on
successful creation. The problem is that both actions are
DispatchActions with the same parameter. As explained in my former mail
I do not want to break that for different reasons.

Is there something I am missing?

RE: Cannot Find Bean in Any Scope

[Satish Kataria]

You are getting the error because you have not defined a scripting
variable for the threadbean.
Simple way of doing that is using the bean:define tag

 

Please let me know if there is any problem in using this

Subject: RE: Cannot Find Bean in Any Scope


Sorry for not being clear about the problem that I
have.

1. I have a JavaBean, which is named as ThreadBean
with lots of properties.

2. My ListThread.java class extends Action.  In that
class, I created a collection of beans.  Each of those
beans is a ThreadBean.

3. By the end of the ListThread.java, I passed those
beans to my JSP in the request scope this way:

  request.setAttribute( "ThreadBeans", beans );

4. In my JSP (I did import the ThreadBean), I have

<%
Collection threadRows = ( Collection
)request.getAttribute( "ThreadBeans" );

int odd = 0;
   Iterator iterator = threadRows.iterator();
   while( iterator.hasNext() ) 
   {
  odd = ( odd + 1 )%2;
  ThreadBean threadBean = ( ThreadBean
)iterator.next();

  .
   }
%>

5. when I tried to write out the properties; for
example:

<%=threadBean.getSender()%> <%=threadBean.getThreadReplyCount()%>
<%=threadBean.getThreadViewCount()%>
..

I got the error message:

- Root Cause -
javax.servlet.ServletException: Cannot find bean

Help with Datavision + Struts

[Miquel Angel]

Hi. We are de developing an application using struts. In this application
we have to develop reports (of course) and we decided to use Datavision. We
want to use datavision in our action classes. We have one problem and we
don't know how to solve it. The problem is:
The user has a form in wich he or she enters some criteria to select the
records to be listed. ?Can I pass the WHERE  clause to datavision as a
parameter? Something like this: ID > 100 AND ID < 500 AND NAME LIKE
'PETER%'. If I can, do you have any example.

Does anyone have  experience with other reporting tool?, is there any other
tool better than datavision?

Thanks in advance.
