RE: Back Button in Struts
You can't really use the javascript:history.back() function to hit the Action class as the history.back does not even hit the webserver. It is an internal client operation, like most javascript is. One solution you might want to try is to create a stack object for each session to track what actions they have run. Then you can implement a fairly decent back button. Haven't done this myself, but know of another project that has. -Original Message- From: Larry Maturo [mailto:[EMAIL PROTECTED]] Sent: Monday, August 20, 2001 9:11 AM To: [EMAIL PROTECTED] Subject: Back Button in Struts How do you implement a generic back button in struts such that it hits the Action Class? When you use something like: A HREF=javascript:history.back()Back/A You go back to the jsp, but miss the Action Class, which is often a bad thing. -- Larry Maturo
RE: Speed issues w/ Strut Tag Library
Here's a good general optimization article... http://www.jspinsider.com/jspbuzz/aug2000/buzz_8_15_2000.html#topic -Original Message- From: John M. Corro [mailto:[EMAIL PROTECTED]] Sent: Friday, August 17, 2001 3:27 PM To: [EMAIL PROTECTED] Subject: Speed issues w/ Strut Tag Library We have a JSP page that's using between 50-75 bean:write tags to display a given bean's information. This particular project is a rewrite of an older ASP implementation and we're seeing some performance issues when comparing the two. (ASP implementation is running from IIS, Java version is Tomcat both running from the same box which has a w2k server OS) This particular page tends to take ~5 sec to load vs. the ASP page which takes ~1 sec to load. Interestingly, the ASP page is hitting a DB while the JSP version (at this point) is hitting dummy values hardcoded in the bean. Two questions. First (a little off subj), in general is ASP faster than JSP. Second, does extensive use of the Struts bean:write tags cause performance issues? (I know that there is an upperlimit of how many custom tags you can use before you exceed the max size of the resulting servlet function)
RE: Problem With Struts and Tomcat

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.Stringkey, java.lang.Objectvalue0, java.lang.Objectvalue1) 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 thesubstitution) does not support internationalizing the replacementparameters 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.Stringkey" parameters instead of "java.lang.Objectvalue0"? Kyle Robinson Systems Consultant Pangaea Systems Inc.

Dirty flag on forms
Has anyone implemented the concept of a dirty flag on an form in Struts? For example if the form is changed then a flag is set and if the user wants to navigate away from that form without "saving" the info changed then they will get a prompt to save. Most of this is JavaScript but each element on the form needs to have some onChange code. Is there an easy way to do this by iterating over a whole form? Ideas?

And after sometesting i found out that a picture can't be larger then 16383 because if it is 16384 then an exception will be thrown. I tested this with the read in buffer: byte[] buf = new byte[16383]; if that number is larger then 16383 i wil get a exception when i write it. so if i keept it 16383 then the first write to out.write(buf, 0, read); will pass but the next bloc will fail.

We have a number of projects, big and small starting up that will be using Struts as a framework. Our main concern with this is how to best estimate with it. Does anyone have any experience with estimating with Struts? For example, how long it takes to do the following: 1. A basic screen (editing, saving to a db, etc.) 2. A medium screen (same as above but maybe with a parent, child relationship) 3. A complex screen (same as above but maybe some special naivgation, extra controls) This may sound broad but any help would be appreciated... Thanks.

logic:equal and nesting
Here's a piece of code that I want to do. However it gives a nested tag error as the closing /logic:equal tag ends up inside the html:form.I basically want the form to do different actions based on the property "title". Anyone know of a better way of doing the same thing? logic:equal name="supplierSearchBean" property="title" scope="request" value="Contractor" html:form action="contractorSearch.do"/logic:equallogic:equal name="supplierSearchBean" property="title" scope="request" value="Supplier" html:form action="supplierSearch.do"/logic:equal Kyle Robinson Systems Consultant Pangaea Systems Inc.

html:select multiple=true problem
Got another problem. I have on a form a select that allows multiple selections. However, I am getting a populate error when the multiple values are stuck into my object. It is declared as an ArrayList. Anyone have a code snippet they can provide to show how this is done? Kyle Robinson Systems Consultant Pangaea Systems Inc. (250) 360-0111
RE: logic:equal and nesting
Thanks. I went with option number two. It's more correct for what I want to do. -Original Message- From: Craig R.

In order to change the destination of the submit, you will need to create some JavaScript that does so on the client side, perhaps when the submit button is presed. (If you do this, be sure you use the same form bean on all of the actions, or Struts is likely to get confused.) Alternatively, you could have the html:form tag submit to a single action, (say, "/commonSearch.do") which could then look at the title property itself and then forward to either "/contractorSearch.do" or "/supplierSearch.do" appropriately.

RE: html:select multiple=true problem
I looked and now I have the code. It still won't populate. Basically all I want to do is pick a couple items from a multiple select and display the picked items on the next page. -Original Message-From: Maya Muchnik [mailto:[EMAIL PROTECTED]]Sent: Thursday, March 15, 2001 10:49To: [EMAIL PROTECTED]Subject: Re: html:select multiple="true" problemSeveral examples are in email archives (I have remembered that).

ActionForm (DataObject) generator?
We are using Struts with an Oracle database as the backend. We don'treally feel like handwriting 100's of java files (one for each table). Does anyone know of a good db table - java object generator? Preferably open source? Thanks Kyle Robinson Systems Consultant Pangaea Systems Inc. (250) 360-0111
RE: Mismatch Between html:options and logic:iterate
Sounds good to me... -Original Message- From: Craig R.

Well, this was one of them :-(. but my vote would be to make the html:options collection attribute act like the logic:iterate collection attribute. My reasoning is that I have several static methods that return collections that could be used to populate the select lists, and it would be nice to access them directly instead of having to get to them via a property in a bean. I also think the current logic:iterate behavior is more useful, and suggest that we change html:options to match. As a nod towards backwards compatibility, how about if we make html:options smart enough, as a special case, so that if it receives a String it will still be treated as a bean name? This behavior would be deprecated, but would avoid instantly breaking old code. Vic Craig

Drop-down list
What is the simplest way to dynamically create a drop-down list (select) that pulls values from a database? Is there a specific tag I should use? Iterator? Kyle Robinson Systems Consultant Pangaea Systems Inc. (250) 360-0111
RE: Drop-down list
I'd remove all the square brackets. If you want to keep them, the parameter
type in setProviderName should be String[].
I don't know for sure though.

Trying to use Multiple="true" attribute for html:select
Help!
O.k. so I declare it like so:
protected String[] providerName;
Then I get it:
public String[] getProviderName()
{
return (providerName);
}
Then I set it:
public void setProviderName(String providerName[]) {
{ this.providerName = providerName; }
}
What am I missing?

Add the attribute to your tag like so:
html:select ... multiple="true" ...
and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:
http://jakarta.apache.org/struts/struts-html.html#select
Hope this helps.

When adding options to a select that are stored in a database, we have
the
action class look-up the necessary information, store it in a bean,
place
the
bean in the request / session, and then use a taglib on the page that
specifies
the source (the bean) and the property (database column) that should
be
used to
populate the select.
This gaurentees that the data in the select list is up to date.

I thought html:options could reference the collection where it is in

This is how we do it...(I think the work simple should be ommitted)
Get the content at the top of the JSP page.
%
pageContext.setAttribute("nameSuffixTypes",
getServletContext().getAttribute("nameSuffixTypes"));

Place this where you want the Drop Down List on the JSP page.
html:select property="suffix"
html:options collection="nameSuffixTypes" property="value"
labelProperty="label" /
/html:select

Introspection
Has anyone used the concept of introspection with the struts framework? I believe the idea of it is that you write a use bean line in your jsp and call the jsp:setProperty name="blah" property="*" and when the form is posted all the properties of object blah get set to the values in the form objects that match the names. Tell me if I'm way off-base and if this is the opposite direction from Struts or not. Kyle Robinson Systems Consultant Pangaea Systems Inc. (250) 360-0111
