RE: ??? STRUTS 1.2.4 FEEDBACK ???

[David G. Friedman]

Niall,

While researching (out of curiosity) a recent help request on how to use
custom ActionForwards with set-property, I actually read the
struts_config_1_2.tld and the ActionServlet class (from CVS). I found that
the tld describes how to set various init-params in web.xml for
ActionServlet which don't seem to exist anymore.  There are no references as
the tld comments describe in the 1.2.4 userGuide\configuration.xml or the
latest ActionServlet.java code. Maybe no one remembered it was an odd
comment in the 1.2 (v 1.8) tld?  Below are the 3 comment sections including
their seemingly obsolete notes on init params:

David

Has anyone tried out Struts 1.2.4?

If so can you feedback - positive or negative.

RE: CustomActionForward -- How do I pick it up in the Action?

[David G. Friedman]

John,

I've been playing around with your issue on 1.2.4 and it all worked
normally. (code examples and plenty of notes below)

I was able to set the global-forwards parameter "type" to my ActionForward
subclass.  I had to shut down Tomcat completely and start it clean to get
that to work. My ActionForward subclass contained a dump property name, yes,
"property" (i.e. getProperty()/setProperty(String)).  I was also able to set
the ActionForward subclass on an individual forward, both in the
global-forwards section and as a nested (inside the Action declaration)
forward using the className="someActionForwardSubclass" parameter.

There is a second way to globally override forwards in the web.xml by
specifying the "forward" init parameter to the ActionServlet but that DID
NOT work for me.  The notes that this should be possible are in the
struts-config_1_2.tld file:



There is nothing in the code.  It looks like the init params "debug",
"detail", and "forward", etc. are no longer valid init-params for the
ActionServlet according to the latest CVS commit at:
http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts
/action/ActionServlet.java?rev=1.178&only_with_tag=STRUTS_1_2_4&view=auto

If you want the example code that I used, here it is.  My package is
com.friedsoftware.struts.

// my ActionMapping subClass:
// ---
package com.friedsoftware.struts;
import org.apache.struts.action.ActionMapping;

public class ActionMappingExample extends ActionMapping {
String commands;

public String getCommands() {
return commands;
}

public void setCommands(String commands) {
this.commands = commands;
}
}

// ---
// My struts-config.xml global-forwards (which work)
// My action always does a lookup for the mapping "success"
// ---






// ---
// My struts-config.xml action setup and forward are:
// ---








// ---
// My example Action
// ---
package com.friedsoftware.struts;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class ActionExample extends Action {
private Log log = LogFactory.getLog(this.getClass());

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
log.info("Checking mapping: " + request.getPathInfo());
log.info("Retrieving the ActionForward named 'success'");
ActionForward am = mapping.findForward("success");
log.info(" ActionForward of type: " + am.getClass().toString());

if (am.getClass().toString().equals(
"class 
com.friedsoftware.struts.ActionForwardExample")) {
ActionForwardExample newAm = (ActionForwardExample) am;
log.info("The cast was successful");
log.info(" Asking for property, it was set to '" +
newAm.getProperty() + "'.");
return (newAm);
}

return (am);
}
};

// ---
// And finally, my logged output showing it works:
// ---
[INFO] ActionExample - Checking mapping: /successDefault
[INFO] ActionExample - Retrieving the ActionForward named 'success'
[INFO] ActionExample -  ActionForward of type: class
com.friedsoftware.struts.ActionForwardExample
[INFO] ActionExample - The cast was successful

[INFO] ActionExample -  ActionForward of type: class
com.friedsoftware.struts.ActionForwardExample

// end of all sorts of code...

Re: Idea for chain and DB transactions

[Sean Schofield]

Craig,
Thanks for your response.  The main problem with that idea would be that I 
would have to count on the connection being in the context and the command 
would have to directly access the database.  I was thinking that my commands 
would be simple "facades" to the DAO layer.  That way I could leave my DAO's 
intact (and would be free to change them when I needed.)

Why not have the first command in the chain get a connection from the pool 
and store it in ThreadLocal?  Then the DAO's can use the connection without 
the commands having to deal with the connection or the datbase logic.  Do 
you see any drawbacks to this approach?

By the way, I do plan on still using postProcess() to the return the 
connection to the pool.

Atta,
You could write your own custom plugin that would initialize the chain 
stuff.  Note that commons-chain is its own project and does not have to be 
directly tied to Struts.  The struts-chain effort is going to use 
commons-chain to handle some of the behind the scenes struts implementation. 
Once its available you can probably piggyback off their plugin to initialize 
the chain stuff.

In the meantime, write your own plugin (use the one in struts-chain as a 
basis).  The plugin should store the Catalog in servlet context and can be 
used by your actions, etc.  Take a look at the CatalogConfiguratorPlugin 
that is in the contrib section of the nightly source tarball.

HTH,
sean

RE: Slow Response Time (Tomcat 5.0.16)

[David G. Friedman]

Shailendar,

You mention "The application seems to be still slow since there is a data
transmitted from Browser to server."  So I have to ask some dumb questions:

1) Are your clients uploading large files?

2) Are those files being compressed by the client?
(compress/zip/winzip/winrar/gzip/etc.)

3) Are your clients performing the above tasks over slow connections, such
as dial-up?

Depending on your answers, the problem might be them, not necessarily Struts
or your server.  The last time this came up, the poster was complaining
about Struts problems when the issue was their clients sending uncompressed
large files (>1 MB) being uploaded over dial-up connections on a daily
basis.  So it depends no the particulars of the client-to-server direction
of tasks being performed.

Hello All,

I am using Struts Framework and Tomcat 5.0.16 for the development of my
application.

The application seems to be working very slow as there is a lot of data
transmitted over the net.
I used the HttpCompression technique to reduce the response time from
the server to browser.
But this has solved the problem in one direction i.e server to browser.
The application seems to be still slow since there is a data transmitted
from Browser to server.

Is there any way i can reduce this.
Like using Apache with Tomcat

Any indication will be helpful

Re: Validation in Struts

[Rogue Chameleon]

In your ActionForm, add the validation to the validate method.

For example, you would have something like this:

public ActionErrors validate(ActionMapping mapping,
 HttpServletRequest request) {

ActionErrors errors = new ActionErrors();

if ((person == null) || (person.length() < 1))
  errors.add("person", new ActionError("ch03.hello.no.person.error"));

return errors;
  }


where 'person' is the name of the select box field.

Use the "required" validator rule and be sure to use the html:javascript tag

Re: JTidy integration?

[Craig McClanahan]

Using a servlet filter would be the easiest way to implement something
like this (no change required to your application or to Struts), but
I'm having a hard time understanding why anyone would want to spend
the extra server side processing cycles for doing this.  It won't have
any affect on the semantics of the HTML page, and won't even be
visible to a browser user unless they use the "View Source" option.

If you're interested in this solely to reduce the number of whitespace
characters, you'd be better off designing a filter that just focused
on collapsing those (which will run a lot faster than a general HTML
tidying application).  Alternatively, if your client browser support
processing compressed responses, you might look at using a Filter that
applies compression on the entire response stream, thereby reducing
the number of bytes sent down the wire.  Tomcat has an example filter
in its source code that does exactly this sort of thing.

Re: Idea for chain and DB transactions

[Craig McClanahan]

Commons Chain (on which Struts Chain is based) has a design pattern
built in for the general case were one command in the chain wants to
allocate resources that will be required for later commands in the
chain, plus the ability to clean up that resource when the chain
completes.  See the Javadocs for org.apache.commons.chain.Filter.

For example, assume you want to allocate a connection from a
connection pool defined as a JNDI resource (the same principle applies
to any other sort of resource allocation factory) -- create a Filter
with the following functionality:

* In the execute() method, acquire a reference to the data source,
  acquire a connection, and store it as an attribute in the context.

  public boolean execute(Context context) throws Exception {
  InitialContext ic = new InitialContext();
  DataSource ds = (DataSource)
ic.lookup("java:comp/env/jdbc/CustomerDatabase");
  Connection conn = ds.getConnection();
  context.put("connection", conn);
  return false;
  }

* In the postprocess() method, call close() on the connection,
  which returns it to the pool:

  public boolean postprocess(Context context, Exception exception) {
Connection conn = (Connection) context.get("connection");
conn.close();
return false;
  }

  Note that the postprocessing method will be called even if an
exception was thrown in a
  subsequently called command.

In all other commands, the execute() method can simply use the
allocated resource, without having to care how it got there:

  public boolean execute(Context context) throws Exception {
Connection conn = (Connection) context.get("connection");
... use the connection to perform database transactions ...
  }

Using this design, you don't have to worry about external storage of
the allocated resources -- just store them under a well known
attribute name in the context object that is passed in to all
commands.

Re: Action mapping Path resolution

[Frank W. Zammetti (MLists)]

I think your getting confused because when you set up a path to an Action,
it's a virtual path, but when it's a forward, it's a physical path, in
BOTH cases it's relative to the root of your webapp.

For instance... You may have an Action that you map to the path
"/my/action/is/the/best/Action.act"  So that string is literally the
target of your form.  Your physical directory structure however probably
doesn't have any of those directories.  That's OK, if this is in an
 tag in struts-config.xml, the resource will be found because the
incoming URI can be mapped to that Action's path attribute.

When you write the path for a forward however, you are referencing a
physical resource (well, usually anyway, assuming it's a JSP).  In that
case, the path you see WILL be a real path, like
"/myProject/jsp/myJSP.jsp" in your case.  The exception is if you forward
to another Action (which you of course can do), then the path will be
"virtual" as before.

On your second point about window sizes, I'm 99% sure there's nothing in
Struts specifically that will help you.  You'll have to open the window
via Javascript and set it's size there.  Just load your popup.jsp into it
and you should be all set.

Hope this helped!

You do the same thing as anyone else.  It does not matter if the request
came from a "web browser" or a "browser plugin" such as an applet, flash, or
some other embedded component.  It is all the same to the servlet container
and thus is the same to Struts.
ok, but if I want use  actionForm with xml flash output I guess it'is 
different. I need translate xml to some things like as form field values 
because Struts work with post data.
Anyway thanks for the answer. I understand that if I send my data  with 
"post" may be actionForm work.
I can use error tag, too?

thanks Lorenzo

Action mapping Path resolution

[Ryan julius]

Hi,

I am trying to master, Struts.

I am creating a struts application with the following settings, and I am getting 
confused with the concept of the struts action "path".

Directory tree:

==

c:\project\adminProject => the root of my project called adminProject

c:\project\adminProject\jsp => for jsp pages

c:\project\adminProject/src/org/mycomp/user/action/AdminUserAction.java

CreateUser.jsp:

=



struts-config.xml:

=









Questions:

1.) I have been explained that the "path is a context-relative path of the submitted 
request starting with / character and omitting any file name extension if extension 
mapping is being used." (ref. Chuck C. book, and ...)

This definition is abstract for me. What is the path of a request? And mainly, which 
context is concerned here? Is it the container context or the application context?

a.) How do you setup that context? 

b.)How do struts resolves the path within its flow of execution?

c.)What are the rules of setting the path in order to avoid errors like "resource 
(/web/jsp/user/AdminUser) not found!"? 

d.)Is there any advantage of setting : path="/web/jsp/user/AdminUser" instead of 
path="/AdminUser"? 



2.) I would like the PopupMenu.jsp being a page into a window of a given size let say 
width=300 and height=200. At the moment, the content of my PopupMenu.jsp is displayed 
into a large window. I would like to dynamically set the size of this window.

Thanks for your reply.

Slow Response Time (Tomcat 5.0.16)

[Shailender Jain]

Hello All,

I am using Struts Framework and Tomcat 5.0.16 for the development of my
application.

The application seems to be working very slow as there is a lot of data
transmitted over the net.
I used the HttpCompression technique to reduce the response time from
the server to browser.
But this has solved the problem in one direction i.e server to browser.
The application seems to be still slow since there is a data transmitted
from Browser to server.

Is there any way i can reduce this.
Like using Apache with Tomcat

Any indication will be helpful


Regards
shailender jain
