RE: what setters do i implement in an indexed tag ?

[Deadman, Hal]

Ignore my previous post because I was mistaken. You don't need a setXYZ(int
index, XYZ x) method because struts will call the "public XYZ getXYZ(index
i)" method and then call the appropriate set method on the bean that is
returned. This worked for me (with last nights CVS):






 /td>



which generates field names like "interestRate[0].monthId"

so struts will call form.getInterestRate(0).setMonthId(somevalue)

I had this in my form class:
ArrayList interestRates; // initialized in constructor and reset()

public InterestRateJBean getInterestRate(int index)
{
if (index > interestRates.size()-1)
{
interestRates.add(index,new InterestRateJBean());
}
return (InterestRateJBean) interestRates.get(index);
}

Again, I just got this to work so I may be missing something.

In the indexed tags write up at
http://www.husted.com/about/struts/indexed-tags.htm, it only mentions the
two types of get methods required in the action form. It doesn't mention the
setters that are required. It looks like the getParameterList() method is
only used by the iterate tag. To populate the form on submit the only setter
needed is:

public void setParameter(int index, Parameter p){...};

In your case that means:

public void setParameter(int index, FieldMapping f) {...};

You probably don't need:
public void setFieldMappings(java.util.Vector newFieldMappings) {
fieldMappings = newFieldMappings;
}
unless you use it in your action to populate the form object before
displaying the form jsp.

I am about to try this myself so this is just a guess.

I've created a page using indexed tags (neat stuff!).
Here is what is currently working for me:
o If i populate the form's vector, values from that vector are displayed in
the jsp
Here is what it not working:
o when the form is posted back, the vector is null (in the struts perform()
method)
I suspect i haven't implemented some sort of setter within the form but i
can't find an example as to what method should be implemented.  I've tried
ArrayList and using parameterList instead with no different result.

java report article says "bye-bye struts"

[Deadman, Hal]

Clearly there are too many java magazines and they will publish anything. In
the July issue of Java Report there is an article titled "Writing a Reusable
Implementation of the MVC Design Pattern" by Prashant Sarode from Brience.
It's interesting because it has a section title of "Bye-Bye Struts". The
section starts out as follows:

"While the Struts framework is a powerful idea, it is not yet a product.
Although excellent in dealing with Web-based applications, Struts is not
ready to take on EJB."

There are other gems in the article but I won't reproduce them all here.

The premise of the article is that the author went looking for an MVC
framework. He found the Blueprint document and liked that but it was too
complicated. He then found Struts but apparently it didn't meet his need for
"a reusable implementation of the MVC pattern." Prashant must be a hard man
to please. I think he wants one framework that can be used for both web
applications and desktop applications. Personally I would rather share the
model components and let my MVC framworks be a little less abstract and more
useful to the task at hand.

I couldn't find the article on-line. I just skimmed the rest of the article
because it it was hard to concentrate or take it seriously after the Bye-Bye
Struts section.

RE: Struts Beta 03 Build Problem

[Deadman, Hal]

Did you get the ant binary distribution or did you build ant yourself?
Building ant yourself may get you a version of ant that supports fewer tasks
depending on what is in your classpath when you build it. Certain classes
such as org.apache.tools.ant.taskdefs.optional.TraXLiason don't get built
unless certain things are found in your classpath when ant is built.

If you have the pre-built ant distribution, make sure the optional ant jar
files are in your classpath. PostgresSQL probably doesn't use the ant style
task which uses org.apache.tools.ant.taskdefs.optional.TraXLiason.

RE: Any Hashmap examples used in jsp page?

[Deadman, Hal]

I don't think what you are trying to do should be done in the JSP by a
struts/custom tag.

Why not copy the value objects in the HashMap to an array based on the order
of the keys in your String array? Then pass the array to the JSP instead of
the HashMap. If you need the keys and they aren't attributes of the value
objects then you can pass the String array of keys to the JSP too.

RE: How do I Internationalize ActionError parameter values?

[Deadman, Hal]

Use the request argument to get the session and then get the locale out of
the session using getAttribute(Action.LOCALE_KEY). If you have a shared base
class for all of your forms (that extends ActionForm) it might make sense to
put a getLocale(request) method in there.

RE: How do I Internationalize ActionError parameter values?

[Deadman, Hal]

Getting the locale object is easy. If you are in an Action perform method,
just call:

getLocale(request);

If you are not in the Action class, you can do what that method does,

Locale locale = (Locale) session.getAttribute(Action.LOCALE_KEY);
if (locale == null)
 locale = Locale.getDefault();

Subject: How do I Internationalize ActionError parameter values?


Hey,

Looking through the archive I found a couple of notes about
internationalizing the ActionError parameters.  I'm talking about the
following:

public ActionError(java.lang.String key,
   java.lang.Object value0,
   java.lang.Object value1)
Construct an action error with the specified replacement values.
Parameters:
key - Message key for this error message
value0 - First replacement value
value1 - Second replacement value

What I want to do is pass in keys from the properties file into the second
and third parameter.  Specifically I want to pass in the prompt keys to
display to the user the fields that are in error.

One possible solution proposed was by Craig as follows:

The java.text.MessageFormat class (which is how Struts is doing the
substitution) does not support internationalizing the replacement
parameters directly.  But how about doing this in two steps?

* Look up the internationalized replacement value from
  a MessageResources bundle

* Use the returned String as the replacement value in the
  ultimate message.

However, I need to get the locale somehow.  It seems alot easier to just
override ActionError to accept keys as parameters.  Has anyone overridden
the ActionError class to accept "java.lang.String key" parameters instead of
"java.lang.Object value0"?

RE: Null PointerException when run with Apache/SSL/Tomcat

This could also be caused by a link URL including the port number which
sometimes caused a new session to be used. A NPE could result when code that
normally expected something in the session didn't find it because the
session was new. As indicated by the other post, this may be fixed in b3.

RE: Size on html:file tag??

[Deadman, Hal]

If your looking at the documentation on the web, it may be newer than your
build. I think the size tag was added to the tld recently. Do you have a
recent build?

RE: Tag Iterate !!!

[Deadman, Hal]

Based on what you are showing in your email, everything looks OK. I don't
think the problem is with the iterate tag. The message
"javax.servlet.ServletException: Cannot find bean client in scope null"
would have to be coming from bean:write which is looking for a bean called
client. It's looking in all scopes (null just means you didn't specify a
scope), so you don't need to add a scope. The iterate tag should put a bean
in the page scope with the name client.

Are you sure that it is the bean:write tag inside the iterate tag that is
causing the error or is there something else on the JSP that you aren't
showing? Try removing the bean:write from the iterate tag and replacing it
with some html.

RE: Resources clarification - is there a work around

[Deadman, Hal]

I am suggesting that with a database it would be easier to specify a bundle
for each page so you wouldn't have to worry about collisions. The table
might look something like this:

bundle (null = default)
key
value
locale

(or you could normalize it so the bundle/key would have many values in
another table, one for each supported locale)

The bundle could be the page name if that's how you want to break up your
properties. You would have one application that helped you maintain your
data rather than having hundreds of files. Of course, you would probably
want to have an export/import utiltity so you could check the properties
into source code control. You can do global search and replace with SQL
fairly easily if you have to. One file per jsp doesn't sound _too_ bad but
if you then support three languages I think it becomes a maintenance
problem.

It would be a fair amount of work to get that going so it's not really an
option for you anyway.

RE: Resources clarification - is there a work around

[Deadman, Hal]

Let me preface this by saying I haven't given this much thought. Since
struts already supports multiple bundles (i.e. with the bundle attribute on
bean:message) would it make since to have struts read all the resource files
from a particular directory or path and use the base filename of the
property file as the name of the bundle? That would allow people to break up
their properties files however they want to. The default file with the
bundle key Action.MESSAGES_KEY would still be used whenever a bundle was not
specified.

I think if I were going to have a huge number of bundles like one per page,
I would pull my resources from a database using a custom
DatabaseMessageResourceFactory. I have considered writing a such a factory
and the accompanying webapp to maintain the translations but I haven't
followed through.

If you are using Weblogic there is an Ant task that does it in the optional

a modified version that works fine. Tomcat has a batch file that will run
Jasper on a whole directory tree full of jsps. I used it once but I never
tried to  run the compiled jsps.

RE: getting a specific ArrayList element

[Deadman, Hal]

Each element in the collection is exposed as a bean with name determined by
the "id" attribute of the iterate tag. So inside your tag you can access
that bean in a scriptlet or with the bean:write tag. The bean will be of
type Object unless you use the type attribute of the iterate tag.

RE: action classes

[Deadman, Hal]

I actually use EJBs for the model objects. I have some non-struts related
JavaBeans that I use for transport objects. These are the beans that I nest
inside Struts action forms. They are passed to EJBs model components. That
way the EJBs have no Struts dependancies and I don't have to duplicate the
JavaBeans in the ActionForm.

The transport JavaBeans don't have any business rules or logic. The business
logic is in session beans and entity beans are used mainly for container
managed persitence. The entity beans typically duplicate the same fields
that are in the transport JavaBeans but the properties are not necessarily
exposed in the remote interface. Not every entity bean has an associate
transport bean and not every struts form has a nested bean. I only use them
for entities with many properties.

I think there is a different term rather than "transport Javabeans" for this
pattern but I forget what it is. It basically allows for methods with fewer
parameters.

You are basically going to have to duplicate the properties in at least two
places or you will tie your model components too closely to your view
components. Another technique for making this a painless as possible is to
use the BeanUtils.copyProperties() method to copy data from the view bean to
the model bean.

RE: action classes

[Deadman, Hal]

Struts allows you to nest your existing beans inside the form class. You
won't need to duplicate the get/set methods. You reference the nested beans
with dot notation. There are examples of this in the html-setters.jsp in the
excercise-taglib webapp that comes with struts.

it. It's real but it's relatively new so you aren't going to see it in use
by really big well known sites. The fact that they are well known means that
they have been around longer than struts.

That's where you will forwarded back to if the validate() function on the

RE: Options tag problem

[Deadman, Hal]

I don't think the option tag will work like that. You can either put your
Hashset in some scope, call it something like "persons" and then use the




Or you could have two methods on your form, one that returns a collection of
Strings for the label and another that returns a collection of Strings for
the value. If they are the same then what you are doing  will work but you need to change the getPersons method
to return a collection of strings instead of beans.

The options documentation is confusing but giving the tag any more
flexibility would only make it that much more complex. The fact that the
attributes "property" and "labelProperty" mean two different things
depending on whether "collection" is used makes it confusing. You basically
need the first usage with an alternate way of specifying the collection.

Disclaimer: I could be confused myself.

RE: Regarding making your own tags with Struts

[Deadman, Hal]

You can change the font of the header by modifying the values for
errors.header and errors.footer in your application resources properties
files.

errors.footer=
errors.header=Validation ErrorYou must
correct the following error(s) before proceeding:

You can write your own tags in struts the same way you write JSP tags
without struts. Look on this page for links to tutorials.

RE: dynamic button names

[Deadman, Hal]

It looks like this was broken in a recent update. The ButtonTag.java needs a
doAfterBody() method in order to set the text instance variable to the body
content. That will make it work like the SubmitTag.java. You should submit
this as a bug on Bugzilla. http://nagoya.apache.org/bugzilla/ If you can't
do that, let me know and I will do it.


/**
 * Save the associated label from the body content.
 *
 * @exception JspException if a JSP exception has occurred
 */
public int doAfterBody() throws JspException {

if (bodyContent != null) {
String value = bodyContent.getString().trim();
if (value.length() > 0)
text = value;
}
return (SKIP_BODY);

}

RE: How to use the new iterate tag?

[Deadman, Hal]

It seems like overkill because the alternative would be simple scriptlet:

<% int i=0; %>

<%= ++i %>


But I think it makes sense to have a tag, my opinion is that the overhead from tags 
should be insignificant compared to the overhead from network and database access. 
Nobody has to use the tag if they think it's overkill. 

I submitted the tag as a low priority enhancement request on bugzilla.

RE: How to use the new iterate tag?

[Deadman, Hal]

Do you just want to display the index? If you do, I just wrote a custom tag that does 
that. It allows me to remove one of the last instances of scriptlets that I have in my 
jsps. It's seems overkill to have a tag that just displays the iterate counter but oh 
well. If nothing else, you can use it as an example of how to access the index of the 
iterate tag.

RE: How to use the new iterate tag?

[Deadman, Hal]

Type should be available as an attribute of the iterate tag. Which tld are you using? 
The tld and the documentation are generated from the same xml file so they shouldn't 
be out of sync. 

I think the iterate tag exposes the index for use by nested custom tags, but I don't 
know if any tags in struts make use of the exposed index. Maybe you have to write your 
own tag to access it?

RE: Urgent help needed

[Deadman, Hal]

Where is your struts.jar located? Have you modified your classpath at all? I
am not sure if struts-blank.war is meant to actually run out of the box. It
may just be shell to get started with. Does struts-example.war work for you?

RE: Checkbox Arrays - Internationalising them?!

[Deadman, Hal]

Do you want bean:message to be able to get the key from a bean method? It
doesn't do that now...

Since  is printing the value of a bean property, your bean
property could use the MessageResources class to do the internationalization
in your bean method.

Inside an action you can get the MessageResource object and the Locale
object by calling these methods from the base Action class:

Locale locale = getLocale(request);
MessageResources messages = getResources();
messages.getMessage(locale,"some.key",args));

where args is an optional String array.

I am not sure how easy it would be for you to pass the messages and locale
objects into your bean and use them there.

RE: Help needed extending BaseHandlerTag

I think weblogic is masking the real error. Put a temporary try catch block
inside your html:form tag on the JSP to trap the real error. If the

RE: Philosophical question(s) related to STRUTS

[Deadman, Hal]

Struts has a bright future, as long as JSPs have a future. I don't think
Struts has any serious competition among JSP-centric MVC frameworks, but
Struts' fate is somewhat tied to that of JSPs. If you decide that you don't
like JSPs then there are lots of competitors to JSPs, mainly templating
languages like Velocity or XML focused solutions like Cacoon/XSP or (soon)
Microsoft WebForms. MS Webforms strikes me as a direct competitor of Struts
since they are both geared towards Webapps. (It's probably not MVC though?)

I personally like JSPs/Struts but it's good that there is competition out
there. I also think the different technologies work well for different types
of web-sites or even different parts of a site. I hope Struts continues to
open up to other non-JSP presentation frameworks. Struts works especially
well for Webapps. If you have a large brochure/informational site, it might
make sense to store that in XML and convert it to HTML in batch via XSLT.
There are probably other examples but I have only worked on a few web-sites
(none using XML).

One thing I have been wondering about recently, are we headed towards a
world where servers serve up XML and XSLT is done on the client? How does
JSP work in that kind of environment?

Webforms:

RE: Checkbox Arrays

[Deadman, Hal]

Don't use the html:checkbox, use html:multibox and use bean:write in the
body of the tag. An html:multibox resolves to an HTML checkbox.

RE: Checkbox Arrays

[Deadman, Hal]

I posted this same response to your Posting Collections question yesterday.
Here it is again. If you use the html:multibox, you can get back an array of
key values instead of an array of booleans. They key values can be Longs,
Strings, whatever, as long as it uniquely identifies the row that you want
to know was checked. If you haven't used multibox, it generates an html
checkbox. The array that will be set in your form will only contain the key
values for the rows that were checked.

Here is the post from yesterday:

I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.

in the jsp form (where restaurant id is a key for the item being deleted):

...



...



in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];

public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}

public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}

I am not sure if initializing the array to new Long[0] is necessary,
probably not.

RE: Logic iterate problems

Have you tried this? It should work as long as whatever is in the Vector has
a method defined like: public String getName();






Put something like this at the top of your JSP just to make sure tabTest is
in there.
<%
Object obj = session.getAttribute("tabTest");
if (obj==null)
{
System.err.println("The action wasn't called before this jsp");
}
else
{
System.err.println("tabTest is a " + obj.getClass().getName());
}
%>

RE: Logic iterate problems

I 
don't think you need the jsp:useBean. You also don't need type="Client". If you 
want to use type, make sure the class is fully qualified with the package it's 
in.

html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.

in the jsp form (where restaurant id is a key for the item being deleted):

...



...



in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];

public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}

public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}

I am not sure if initializing the array to new Long[0] is necessary,
probably not.

RE: Potential Security Flaw in Struts MVC

[Deadman, Hal]

It's 
fine to nest a JavaBean in an ActionForm if that bean is just a transport object 
that is passed to EJBs but it probably isn't a good idea to nest your model 
objects directly in the form. 
 
If you 
are going to nest a javabean in a form you don't need the getName()/setName() 
methods, you can just have a getUser()/setUser() and reference the properties of 
the nested bean by labeling the field in your jsp as 
"user.name".

  Ah, this maybe a problem in the way I've adapted 
  Struts.  I reflect all UserForm method calls directly into the contained 
  User object owned by the UserForm.  So for instance, I have
   
  public class UserForm extends

  user.setName(name);
      }

  }
   
  Now can you begin to see my original

There is a security risk here as you describe, if (and 
only if) you are using a generic introspection-based function (like 
Struts' PropertyUtils.copyBean) to copy the values from the UserForm 
object to the User object. There are several ways to avoid this

class.2. In UserAction, don't use the generic bean copy utility -- 
instead, manually copy the values, excluding the admin flag.3. As a 
smarter alternative to #2, don't use a generic bean copy utility -- 
instead, write an intelligent copy function in the User class, which 
"knows" that it's copying FROM a UserForm, TO a User, and therefore, 
skip the copying of the Admin flag.BryanJeff

  security flaw in struts that I would like to hear from others 
  regarding.
   
  Consider a simple set of struts classes 
  that represent a user in a system. You would probably have classes 
  that look something like this:
      User    
              (the model 
  representing the user)
      
  UserForm        (an enrollment form for 
  a new user)
      
  UserAction        (Saves the UserForm 
  information to db, etc)
      
  The User class would have accessors and 
  modifiers like getFirstName(), setFirstName(), 
  getAdministrativeUserFlag(), setAdministrativeUserFlag(), etc.  
  The basic implementation of the UserForm is to take the UI form data, 
  introspect the beans, and call the correct modifier of the UserForm 
  bean based on the fields contained within the UI 
  submission/form.  A developer of course would not expose the 
  "Administrative User Flag" option on the UI for enrollment (that would 
  be found possibly in some other administrative-level module).  
  However, if someone is familiar with the db schema and the naming 
  convention the developer used, that user could subvert the application 
  by writing his own version of the UI which contains an "Administrative 
  User Flag" field (or any other field for that matter) and the basic 
  form processing in Struts will kindly honor the request and set the

I assume you have you looked at Jmeter? http://jakarta.apache.org/jmeter I

You can use the html:link tag to pass parameters. The example shows how to
pass a single parameter, there is another method involving a Map that lets
you pass multiple key/value pairs as parameters.

RE: Confusion with form beans

I am not sure what the default is but you should specify redirect="false" if
you are passing things on the request object. That will cause a forward
instead of a redirect. If the default for redirect is true then the
/ShowLog.do action will be requested with a new request.

RE: Problem with bean:struts tag

I think bean:struts is used to access configuration information from
struts-config.xml. Are you trying to use it to access the properties of a
particular form instance? You can do that with bean:write directly if the
form is already in some scope.

Your best bet is to display static text for the existing entries because I
doubt HTML supports disabling a select box. You would probably need to use
Javascript to prevent someone from changing a select option but that would
be annoying. If they can't change something, why put it in a select box?

RE: how to access related ActionForm from within .jsp?

[Deadman, Hal]

You are using redirect="false", correct? It shouldn't matter what type is
used when the action form is put in the request. setAttribute takes an
Object so you can put anything in there but it will actually be the type of
the form bean specified in struts-config.xml. Can you submit the section of
the struts-config.xml file that contains the actions you are using? There
should be one action that forwards to the jsp with a redirect=false. There
should be another action that your jsp submits to. Both actions should use
the same form. You may want to submit part of the jsp that tries to access
the form bean.

RE: how to access related ActionForm from within .jsp?

[Deadman, Hal]

Let me ammend my comment. The formbean will only be available in the jsp if
the action that forwards to that jsp specifies the form when it is defined
in struts-config.xml. Otherwise the formbean isn't created until the jsp
submits to the action that is defined as having the form.

RE: how to access related ActionForm from within .jsp?

[Deadman, Hal]

The form bean is associated with an action, not a jsp. The jsp may contain
an html:form which references an action, thereby gaining access to the form
associated with that action. A jsp could have multiple html:forms. 

The form bean associated with the action is available in request scope for
the jsp but I don't know how you would get access to it without using the
name of the form. Is there a struts tag that will get actionmapping values
when given the name of the action? That would allow you to get the form bean
name using the same action used by the html:form. 

Maybe you could use the bean:struts tag to get the action mapping and then
get the form from that.

RE: Frames, concurrency, and EJB Stateful Session beans - a probl em.

[Deadman, Hal]

I like this. I have seen the business interface idea described before but I
like the handler as a way to hide EJB calls from the front-end code. Do you
typically access entity beans from stateless session beans or do you call
entity beans directly from the front end? Do you have business interfaces
and handler classes for both entity beans and session beans? 

>From the original post, why not store state somewhere else besides the
stateful session bean? I haven't run into a reason to use stateful session
beans in a web application where there are plenty of other places to store
state (cookies, session, db). I would be interested to hear when people have
found them to be useful.

RE: Communicating with EJB's from Action

[Deadman, Hal]

I like this description, mainly because it sounds like what I have been
doing. Something like this might make a good section in the documentation -
Struts & EJBs. I would consider the stateless session beans part of the
model because they contain business logic. You also talk about "basic value
checking of attributes". Would you also do this same value checking in the
ActionForm validate method?

Don't 
put WEB-INF/classes in your classpath and don't put struts.jar in your 
classpath. Any jarfiles in WEB-INF/lib and the WEB-INF/classes directory get 
added to your webapps classpath. Having them in a the classpath for 
the appserver will cause problems.

RE: More on my copyProperties/EJB woes

[Deadman, Hal]

Although copyProperties to an entity 
bean might work, it would be making a call through the remote interface 
each time it sets a property on the entity bean. I think it's good practice 
to minimize the number of remote calls made to an EJB. (Often in practice the 
calls are not really remote but it's good to pretend like they could be.) That 
would allow you to separate your JSPs and EJBs or use Tomcat for JSPs and 
Weblogic for EJBs. Normally instead of calling set methods on an entity bean 
from the web tier, I call a session bean and pass a simple JavaBean to it that 
isn't tied to Struts, often the bean may have been nested in an ActionForm. Then 
I have a create or an update method in the entity bean that accepts 
the JavaBean as an argument. I don't always put all the getters and setters 
for individual fields in the entity bean remote interface unless I need them. 

 
Sorry 
if this isn't helpful, I would be interested to hear if anyone disagrees.

I need to determine which of several html:image buttons in a form has been
clicked.  I have tried the following:

public class MyForm extends ActionForm {
...
private MyFormBean bean1 = new MyFormBean();
private MyFormBean bean2 = new MyFormBean();
...
public MyFormBean getBean1 () {return bean1;}
public void setBean1 (MyFormBean bean1) {this.bean1=bean1;}
...
}

The MyFormBean class has accessors for x and y.

Unfortunately, although the request contains bean.x and bean.y values
whenever the button with the property "bean1" has been clicked, getBean1()
returns null.

Am I doing something wrong?  Is there an alternative method of
distinguishing between html:image buttons?

RE: Database pooling code

[Deadman, Hal]

Weblogic's connection pooling lets you specify the SQL statement that you
want to test with. In Oracle you would typically test a connection with
"select dummy from dual". I think you need to allow the test SQL statement
to be configured for each pool. If an exception is raised when it is
executed you can assume the connection is bad.

RE: JSP includes of

[Deadman, Hal]

You need to use <%@ include file="/include/header.jsp" %> instead of
jsp:include.

When you use jsp:include it is invoking a seperate jsp. The include file
directive will do an inline of the code from the other file which doesn't
have to be a complete jsp, it may be just a code fragment. For that reason I
would rename header.jsp to header.inc or something. That way if you are
doing a batch jsp compile you will be able to tell jsp fragments from full
jsps using the extension.

Does this assume that you have loaded a Collection of LabelValueBeans in the

Place this where you want the Drop Down List on the JSP page.

RE: data-sources for oracle

[Deadman, Hal]

If I recall correctly, that error happens when the database isn't being
found. Is the Oracle listener running and properly configured? If it is and
you can connect from other applications then maybe your jdbc url is wrong.

Your url should look like this:
jdbc:oracle:thin:@SERVERNAME:1521:SID

Simple question:  I'm trying to test an oracle database connection via the
 configuation settings.  Below is a sample from my
struts-config.xml file:









where SERVERNAME is the hostname of the database server
and SID is the oracle sid 

This produces the following exception:

org.apache.struts.action.DATA_SOURCE java.sql.SQLException: 
The Network Adapter could not establish the connection


Any insight would be greatly appreciated.

RE: How does nested syntax in property attribute work

[Deadman, Hal]

In your example you would have a nested JavaBean in your form with a get
accessor that retrieved a nested JavaBean with a definition something like
this:

private AddressBean mailingAddress = new AddressBean();

public AddressBean getMailingAddress();

The AddressBean would need to have getters and setters for a street
property. getStreet() and setStreet(String s).

When you submit the JSP, Struts would call the getMailingAddress() method to
return the nested javabean and then Struts would invoke setAddress and pass
in the data from the input text field. 

You would use this Struts feature if you have JavaBean already and you don't
want to duplicate all of its accessors in the form bean. Or if you want to
be able to pass the data in one JavaBean to a model component but you don't
want to pass Struts objects to your model components.

Hi,

In some of the e-mails I have seen nested syntax being used for property
attribute, e.g.,



what does that mean? Is it that the getMailingAddress() method of the bean

RE: Stupd question about Struts and EJB.

[Deadman, Hal]

I use EJBs without using copyProperties although it's a matter of
preference. I have a set of JavaBeans that you could call "Data Beans"
because they are often similar to my Entity Beans and they don't contain any
business logic. They are struts free and I pass these data beans to some EJB
components. I often nest the data bean inside the ActionForm class as a
property and use the Struts nested property functionality to populate the
Data JavaBean directly. Sometimes I don't use a nested JavaBean and I just
pass the individual properties of the form to the EJB component. I like
using nested java beans better than calling copyproperties because if I have
a Databean anyway, I don't want to have to redefine lots of getters and
setters in the Struts form bean.

My understanding is that with struts you should keep your EJBs entirely
independant of
anything to do with struts or servlets. You can and should however have
a standard naming
convention for the getters and setters across the EJB, the ActionForm
and the html form elements.
this allows you to call PropertyUtils.copyProperties(java.lang.Object
dest, java.lang.Object orig)
when you are ready to store the details entered by the user.

Please let me know if this does not sound right.

RE: Is the struts example itself is multi-thread safe?

[Deadman, Hal]

The example is thread safe. Methods don't need to be synchronized if they
aren't manipulating a shared object such as an instance variable. If your
action class doesn't have any instance variables and it only deals with
local variables and parameters then there is a good bet that it is thread
safe.

RE: Struts, WebLogic 6.0 and template tags

[Deadman, Hal]

I am not sure what you are looking for. The component library comes with
examples including a struts-template example that uses the component
library. 

The issue with components I was complaining about, albeit not clearly, was
that if a jsp that is part of a component instance and the jsp throws an
exception, the code surrounding the include will trap the exception and
print it to the browser. I would prefer that the exception was not caught so
that I could set up some global handler. Trapping the exception and printing
it to the browser means that the site operator won't know users are
experiencing trouble. 

Below is some of the offending code from
s1.struts.taglib.component.IncludeTag.java. Fixing it would involve trapping
the exceptions and throwing a JspException. Unfortunately that has its own
problems because JspExceptions can't nest the root exception so you don't
know exactly where the error occured. At least you know that something bad
happened. I am not planning to fix this problem for the time being, I am
just planning to write the jsps so they don't fail. :)

Hi, we like to use Struts with Bea WLS 6.0 for a B2B application. Currently
I am developing a prototype and the first tests under Tomcat worked fine. I
used the Struts template tags for a page design with header, navigation menu
and content. An example:

<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>

I tried to debug the application an it seems as if the setBodyContent()
method of class PutTag is not invoked, so that the bodyContent member
variable is null. This leads to a NullPointerException in the method
hasBody().
Is that right? Is there a workaround? I like the template tags, so i don't
want to give them up.

By the way: Is the problem described in msg01892 (PropertyResource problem

Hello, Torsen,

It is not an answer to your question. But I would like to use this email and
ask the struts development team about compatibility template library and
components library (http://www.lifl.fr/~dumoulin/components/). Components
allow
to define "instances" to reuse them with different parameter values. They
have
good examples how to use them for implementation. They do not have a "role"
attribute yet. Both components and templates have a lot of common. Why not
combine the best parts both of them and put under struts project before 1.0
release?

RE: help! confused over forms and errors and oooh, other stuff :-)

I don't know if I understand your question but would making the input
attribute of the action another action give you the opportunity to retrieve
data that the jsp form needs before the jsp is displayed? I have a form that
needs a drop down populated from the database before the form is displayed.
I can never go to the jsp form directly, I always reference the action that
gets the data needed by the jsp. The action returns a forward which forwards
to the jsp with redirect="false".

Subject: netscape 4.7x, session ids and struts




Using netscape 4.7x on either solaris, linux or windows, the
struts-example fails, because I am bounced between two different
sessions.

The symptom indicates to me that netscape keeps separate lists
of cookies for the following URLs:

http://myhost
http://myhost:80

As one goes through the struts example, the URL is
sometimes displayed as myhost, and sometimes as myhost:80,
and I am never allowed past the login because the user
information is kept in a session associated with myhost,
and can't be found in a session associated with myhost:80.

Environment: struts nightly download as of Feb 12, 2001.
Tomcat 3.2.1, mod_jk, apache 1.3.12 on RH7.

I have all cookies enabled in netscape preferences, with
"Warn before accepting a cookie" also turned on for debugging.

1. When I try the struts-example with the following URL:

http://myhost/struts-example

Netscape asks if I want to send the cookie JSESSIONID=f78s0eymd1,
and I click OK.

2. I select the "Log on ..." link.  Then the logon form is displayed at
a
   URL of
http://myhost:80/struts-example/logon.jsp;jsessionid=f78s0eymd1

Note the cookie in the URL because struts doesn't yet know if my browser 
accepts cookies.  Also note the port number 80 in the URL.

3. I enter user:pass and Submit.  

LogonAction logs the following message:

2001-02-15 01:59:47 - path="/struts-example" :action: LogonAction: 
User 'user' logged on in session f78s0eymd1


The mainMenu.jsp page is displayed, with a URL: 

http://myhost/struts-example/logon.do;jsessionid=f78s0eymd1

(note no port number is in the URL)

4. Then, when I select "Edit your" the netscape question box pops up
asking if I want to send a cookie JSESSIONID=ynsmafyqr1.
The URL is shown as
http://myhost:80/struts-example/editRegistration.do?action=Edit
 
This shouldn't happen, it should use the first session id!

5. When I click on OK, then, EditRegistrationAction logs the following
error:

2001-02-15 02:00:55 - path="/struts-example" :action:  User is not
  logged on in session ynsmafyqr1


The logon.jsp form is again displayed.  If I enter user:pass, then
LogonAction reports a successfull login in session f78s0eymd1
(the first session id again!)

When I select "Edit ..." I get the same error from
EditRegistrationAction about "User is not logged on in session
ynsmafyqr1".
And so on, ad-infinitum.

If I disable cookies in netscape preferences, then things
work with URL rewriting, and EditRegistrationAction forwards me to
registration.jsp.

The problem also does not show up with IE 5.

Also, at step 4, if I manually enter a URL of:
http://myhost/struts-example/editRegistration.do?action=Edit
then EditRegistrationAction succeeds and forwards to registration.jsp. 


If I am right about netscape keeping separate cookie lists, then perhaps
a workaround is for struts (specifically the html taglib) not to add
the port number when generating URLs?

I haven't tested this solution.  

Someone must have run into it also?

RE: Unable to start Tomcat with Struts

[Deadman, Hal]

The following was posted by Craig yesterday and it should answer all of your
classpath questions related to struts.jar. The short version is just put
struts.jar in WEB-INF/lib and do not put WEB-INF/lib in your tomcat
classpath. Do not put it any other location that tomcat can see. 

---from craig

There has been some confusion around the issue of placing "struts.jar"
on your CLASSPATH at execution time, in a servlet container like Tomcat
that makes all such libraries visible to web applications.  This message
is an attempt to clarify the issues, and document why this is
prohibited.

* The "struts.jar" must appear on your classpath at
  compile time for your web application.  The easiest
  way to make this happen is to use an Ant "build.xml"
  file (like Struts itself does) that sets the classpath
  dynamically, or create a custom shell script that sets
  the classpath temporarily for compiling Struts based
  classes.

* The "servlet.jar" file (from your servlet container) must
  be on your classpath at compile time as well, because
  your application's Action classes will refer to interfaces
  that are defined here.

* For reasons discussed further below, "struts.jar" MUST NOT
  be on your system CLASSPATH when you start your servlet
  container (in particular, this applies to Tomcat).

* Placing JAR files in $JAVA_HOME/jre/lib/ext (the system
  extensions directory for Java2) is the same as placing them
  on the classpath.  In other words, you will NOT want to put
  "struts.jar" or "servlet.jar" there.

* For Tomcat, placing JAR files in the "lib" directory (as opposed
  to the WEB-INF/lib directory of your web app) causes them to
  be added to the CLASSPATH automatically.  Therefore, you should
  not put struts.jar here either.

The reason that putting "struts.jar" on your classpath is a bad idea has
to do with the way classloaders work in most servlet containers.  The
details differ between them -- but here is the scoop for Tomcat (3.x and
4.x):

* The library files that are placed on the CLASSPATH when
  Tomcat starts up are made visible through the "system"
  class loader.

* Each individual web application has a custom class loader
  created for it, which makes the classes in WEB-INF/classes
  and WEB-INF/lib visible.  The "parent" class loader of this
  custom class loader is set to the system class loader mentioned
  above.

* When classes are loaded, the JVM starts at the bottom of the
  hierarchy of class loaders, with the webapp class loader, and
  works its way up the hierarchy until it finds that class.  Thus, if
  you have struts.jar in the system classpath, classes from struts.jar
  will be loaded by the system class loader instead of the web app
  class loader.

* When a loaded class references other classes, it looks in its own
  class loader first, and then up the hierarchy.  Under NO circumstances

  will it go down the hierarchy.

* Therefore, if a Struts class is loaded from the system class path,
  that class CANNOT see any of your application classes in
WEB-INF/classes
  or WEB-INF/lib -- you will get ClassNotFoundException instead.

This is the reason that the Struts example application will not run when
you have "struts.jar" on your CLASSPATH.  The digester module of Struts
is loaded from the system class path.  Therefore, it cannot see the
"User" class of the example app, because that class is under
WEB-INF/classes.

If you find that you need to put "struts.jar" on your system classpath
to make Struts work in Tomcat, that means your Tomcat install has been
corrupted.  If you find that your own app will not work UNLESS
struts.jar is in the system classpath, there is something about your
application organization that needs to be analyzed in detail.

David,
I tried having the struts.jar in both places that you mentioned and made
sure the classpath reflected the location. But no change...I am still
getting the same error.  Should I completely remove the jar from one
location if I am pointing to the other location in my classpath?  Would that
create problems?  Still not functional.

Here is another possible clue from a list member:  (does this help?)
"error when the database servlet starts up and tries to
load user objects from the persisted data in the database.xml file.
For some reason, the class loader isn't finding
org.apache.struts.example.User although it is definitly in the right
place."

Any info is appreciated,
Jessica

Check where the struts.jar file is placed.  I had this problem when the jar
file was placed in the tomcat\lib directory rather than the
tomcat\webapps\xx\web-inf\lib 

RE: Confusion about struts.jar in classpath

[Deadman, Hal]

Do you have struts.jar in the WEB-INF/lib directory of the webapp you wrote
yourself?

Yes with struts-example only I don't need to put 'struts.jar' in my
classpath but things are totally different if one has developed/deployed
another application also.

Maybe I will give a wrong answer. I think when you have a correct full
application as *.war file you do not need to use CLASSPATH for this
application, but when your
application is not as "good, full, packed" application you need
something,... But what - CLASSPATH or put struts.jar under tomcat/lib ?

I do not build yet my application and do not have your experiment. I have
tested only struts-example.war.

RE: Using ActionErrors

[Deadman, Hal]

I 
haven't tried it but I thought that you could specify the property attribute on 
the errors tag and it would pull out the error that has that property. When you 
add to the ActionErrors object the property is the first argument. You should 
probably use the property name that cooresponds to the property of the form 
field.

how to determine size of collections using tags

[Deadman, Hal]

Is there a way to determine the size of a collection that one might iterate
over using struts tags rather than a scriptlet? I often want to display one
thing if the collection is empty or I want to iterate over the collection.
The only thing I can think of involves adding a get method to the JavaBean
containing the collection that returns the collection size . That would let
me use the logic:equal tag to check the property. Is there a non-scriptlet
way to do this without adding a method to the JavaBean?


// print message about lack of order line items 



   // start table
   
// show each line item
   

html:img tag url rewriting

[Deadman, Hal]

When using the 
html:img tag with the page attribute it will do url rewriting but that doesn't 
seem to work on some webservers. 
 
This doesn't 
work:
http://jakarta.apache.org/images/logos/tomcat_3.gif;jsessionid=123123
 
Is there a way to 
turn off the url rewriting and have the img tag still add the appropriate 
context to the image path?

bean-cookie.jsp

[Deadman, Hal]

The struts documentation says 
this in 
.../struts-documentation/api/org/apache/struts/taglib/bean/package-summary.html
You must use  
to introduce a reference to an existing bean, if you wish to reference that bean 
with other standard JSP tags (such as  or 
). If you only wish to reference such beans 
with other Struts tags, use of  is not 
required.
The bean-cookie.jsp page in the 
struts-test application uses  but does not first use 
jsp:useBean. This makes Weblogic 6.0 very angry and it fails to generated any 
java code let alone compile the jsp. 
The jsp 1.1 spec implies that the 
jsp:useBean tag does not need to be used before using 
jsp:getProperty.
From page 66 of the 
spec:
An  action 
places the value of a Bean instance property, converted to a String, into the 
implicit out object, from which you can display the value as 
output. The Bean instance must be defined as indicated in the name attribute before this point in the page (usually via a useBean action).
end of 
spec
Either the struts documentation 
should be changed to be less emphatic about the use of 
jsp:useBean or the bean-cookie.jsp should be changed to be nice to 
Weblogic. It could use bean:write only and not use jsp:getProperty. I have 
always assumed the bean:cookie tag didn't work in Weblogic 6.0 because the 
bean:cookie test page didn't work. Maybe there should be a separate test page 
to assess the ability of a jsp engine to use jsp:getProperty for beans 
defined by means other than jsp:useBean. That seems like something the J2EE 
certification suite should test for rather than struts.

BUG: weblogic 6.0 multi-box release bug

[Deadman, Hal]

The name property in 
Multibox.java gets defaulted to Constants.BEAN_KEY but the release tag sets it 
to null. This causes it to bomb out in weblogic 6.0 because the name is 
null the second time the tag is used on a page. Actually, I haven't tested 
this yet but it seems to make sense. 
 
 
    protected String name = 
Constants.BEAN_KEY;
 
    /** * Release any 
acquired resources. */    public 
void release() {
 
 super.release(); name = null; property = 
null; value = null;
 
    }
