Re: db error
It has been a while since i used oracle, but that url looks wrong:
jdbc:oracle:thin:oci8:1521:ora9i
Can you have thin and oci in one url?

Check your database is up before trying to connect to it. If it is and

can ping the database from your application server box, then check your

Re: Does instanceof work?
Neither are valid:
http://jakarta.apache.org/struts/api/org/apache/struts/taglib/logic/package-summary.html
According to the jstl doc I have, instanceof is reserved, but not
implemented.
If you are not concerned about subclasses of foo.MyType, you could
probably use this:
c:if test=${myBean.class eq foo.MyType}
...
/c:if

Larry [EMAIL PROTECTED] 03/15/04 2:20 PM I did a google search on this and didn't really come up with anything useful. Before I implement this myself, is there an existing implementation of parsing a search string which would produce tokens similar to how Google or other search engines parse search strings. For example, I would like to parse a search string into tokens where tokens are delimited by either a blank space or a quoted phrase. So the string: 'Struts web presentation tier' would return 2 tokens: - Struts - web presentation tier but the string: 'Struts web presentation tier' would return 4 tokens: - Struts - web - presentation - tier Any help is appreciated. robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Date attribute in ActionForm
Bean utils (what struts uses in this case) sucks when it comes to parsing anything but Strings. Generally what I do is make put String getter/setter methods on the Form, then in those (or in the Action) use a SimpleDateFormat to parse the string into a date. One other thing to note there is that the date format MM/dd/yy will parse 1/1/04 as 01/01/2004, but 1/1/4 as 01/01/0004, so you need to handle that yourself. Same trick with numeric classes.

Re: [OT] JSP or Velocity
[EMAIL PROTECTED] 02/27/04 5:44 AM
I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative
newbie
After looking at velocity, I am certainly of the opinion that it adds no
value over
jsp2/jstl. It offers absolutely nothing that the jsp2/jstl combination
does not.
The only difference is that velocity is a bit more terse (if/else/end
instead of
c:choose/c:when/c:otherwise) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in
tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study
was cleary biased towards velocity and had never even considered JSTL
(which
in all fairness may not have been available at that time). Looking at
the code
(both the velocity and jstl versions are below) I think that velocity
clearly had
an influence on the jsp2/jstl constructs.
The first thing I noticed was that the two pages do not do the same
thing.
The jsp turns off the session (the vm does not). The jsp stores
variables that
are never used which were factored out in the vm version. The vm version
is missing required code (for example, the repCode and urlEvent
variables
are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need
to use scriptlets in jsp1/jstl pages, and I suspect with jsp2/jstl, you
will not ever
*need* to.
With struts, you do not need to use jsp:useBean tags either because
the controller
does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you
cannot have things like if/else/end because they are unbalanced, but
other than
that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the % %
stuff, we
get something more like this:

It does not generate the proper path! I have been advised to use this instead: link href=html:rewrite page='/css/main.ss' rel=stylesheet type =text/css/ The problem is that the this does not work since it is not valid XML.

Re: [OT?]Tomcat multiple users developing
1) How do you share the same application development? Do you use a strategy? We are testing our business objects outside struts, Are you all sharing a single tomcat instance for development? If so, stop now! :-) Set up a version control system (like cvs), and use one instance of tomcat per developer (on each workstation). That way only your changes affect you. Update from cvs often and commit when your code works. 2) Is there another way to tell Tomcat that a class has been changed instead of reload the application or set the reload=true attribute in the context? No. Larry - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: struts and ibatis
We use it where I work on a daily basis. It is simple to use, rock
solid, and very durable.
There are two major components to iBATIS: the DAO layer and the SqlMap
API.
The DAO layer provides a way to create Data Access Objects to hide the
implmentation from the application. For example, we have DAOs based on
SQL, a filesystem, and LDAP. None of the applications know or care about
the source of the data, only the interface needed to get the data. To
the application, the interface is the same, regardless of how the data
is fetched under the hood.
The SQLMap API provides a way to use JDBC without having to deal with
all the junk that comes with it (i.e., the nested
try{}catch(){}finally{} blocks to make sure resources get allocated and
deallocated properly). It takes the SQL ResultSet objects and converts
them to more generic classes (like Lists, Maps, and beans) that allow
your application to work with data without making it a mess because of
the JDBC code. Because it removes the JDBC dependancies from your code,
it fits nicely with the DAO layer.
If you need help getting started, go to http://www.reumann.net and read
the tutorials. Rick does a great job making this clearer.
As Daniel mentioned, since you get the source with it, you can track
down issues when you come across them. Speaking from experience, they
are few and far between, but when you do run into one, the code is
pretty simple to follow, and Clinton Begin is real open to patches and
suggestions, and fast to get them in.

Re: Struts plugin question
That seems like a questionable design (dependancies between plug-ins), but one possible solution might be to make plug-ins #2..n not really plugins, but components that plug-in #1 uses. Then use the configuration for plug-in #1 to specify which components to make available. That would also eliminate a Struts dependancy from your 2..n components. Larry [EMAIL PROTECTED] 01/16/04 10:12 AM Hi all, In my application I have to connect to MBean server and registers some MBeans, that will be then available (thru an interface) to my application. For doing that, I was thinking of writing a plugin that contains my JMXAgent (plugin1) to abstract the connection to MBean server (different implementation may have different way to connect to it) and one plugin for each MBean that I need to register (let's say, plugIn2 .. n) Plugin2...n will retrieve plugIn1 in order to register themselves with MBean server. Assuming that I adopt this solution, plugin1 must be loaded before any other plugIn.. and I was wondering if struts was loading plugIn in the same order that I declare them or randomly.. Anyone can answer?

Re: iBatis DAO + Hibernate?
I am working in an environment where we are mixing the two. My advice to you is to *not* do it. Pick one and use it as it was intended to be used. I personally prefer iBATIS. It is very simple; it plays well with existing databases; it allows you the flexibility, commodity and performance tuning of sql; it provides object wrappers for your data. All while staying in your DAO and out of your application. From my experience, if you are using hibernate, you write hibernate applications, not java applications that use hibernate - even if you try to wrap it so that it is not used directly. Trust me, we did. If you are willing to accept that, hibernate may work for you. Some other factors to consider: - How many developers know hql vs sql? - How much time will it take for a new person to learn the idiosyncrasies of the tool (and they both have them)? Larry [EMAIL PROTECTED] 12/16/03 9:40 AM We're needing to roll out DAO and ORM in our webapp... been evaluating hibernate and it looks awesome, but we'd like to insulate our app from that, has anyone tried using iBatis' DAO layer then plugging hibernate underneath that? -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [OT] RE: iBatis DAO + Hibernate?
The iBATIS DAO is for sure *not* sqlmap or jdbc specific. I have used the iBATIS DAO for LDAP and file system based data access. Larry [EMAIL PROTECTED] 12/16/03 3:35 PM From: Ted Husted [mailto:[EMAIL PROTECTED] You might be confiusing the iBATIS SqlMaps framework with the seperate and distict iBATIS DAO framework.

Re: Question regarding ActionForms.
Welcome to java 101, formerly known as the struts-users mailing list.
Object references are passed to method calls. While that reference
cannot be changed, the object that it references can. On the other hand,
if you create a new action form and assign it to the form parameter,
nothing will happen because that reference cannot be changed.

[EMAIL PROTECTED] 12/01/03 8:42 AM
Hi,
I am currently using Struts 1.0.2 and have notice something with regard
to
handling of ActionForms.
Why is it, that in the perform() method of my Action I am able to
modify
the passed-in ActionForm and all modifications that I make to the
ActionForm in my Action have effect on the ActionForm in the session,
without the need to reset the modified form in the session. e.g.
public ActionForward peform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,
)throws IOException, ServletException
{
MyForm myForm = (MyForm)form;
form.setMemberA(valA);
form.setMemberB(valB);
// why dont I have to do the following: session.setAttribute
(myFormName, myForm);
return success;
}
I thought that since Java passes method arguments by value and not by
reference, then I would have to reset my modifed copy back into the
session
for changes on the form to be visible in the form in the session ?
Any insights on how this mechanism works would be greatly appreciated.
Thanks,
Sepand

Why not put this in ApplicationResources and then use the bean:message

Import the class in your jsp, then you can directly access it.

Subject: Accessing a static final constant from Class in JSP
Hi,
I have a class called ProjConstants.java which is a static class
with
some static final constants here is the sample
public class GSOPConstants{
public static final String LINK_EDIT = linkEdit;
}
How can I access this LINK_EDIT constant from JSP
without
using scriplets???
Any help appreciated.

RE: Form data vs request attributes
The reason I don't do this is because if the form is in session scope, it hangs around consuming memory until the session goes away. As a caching mechanism, this bites rocks, because it is cached for each user. :-/ By putting this type of stuff in request scope instead of on the form, it becomes transient regardless of where the form resides. But if you use a DAO layer with caching (like iBATIS), one copy of this stuff can be cached (globally) so you are not hitting the database all the time. Larry [EMAIL PROTECTED] 11/18/03 4:41 PM From: Mainguy, Mike [mailto:[EMAIL PROTECTED] Although, I don't really see a major problem with storing the options in the form itself (just to make things simple). Anybody have a compelling reason NOT to do this? i.e. I put my statesCollection as a property on my ActionForm with a List datatype. Then I can just use the form property to populate my options. Every time Struts instantiates your Form object, it also creates that list of states. If you have 'state' on more than one form, there's another list, times how ever many users have forms going at any one time. Since the list of states is unlikely to change, I think it makes more sense to put the list in application scope (as a context parameter) and have only one instance of it. However, memory is cheap, so it's probably not going to matter where you put it as long as you're happy with your decision. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: PDF File Display in JSP-Struts
Why would you ever do this? This looks like a complete and total kludge.
If you are sending back binary data (application/pdf), just do it from the action
class using the response.getOutputStream() and return null from the execute method.
Advantages:
- you already have everything you need right there
- you eliminate the entry in struts-config
- you eliminate a useless jsp
- you can specify any content type (not just one per jsp)
- you get better exception handling
- the list could go on and on...

something like this (using a custom fo to pdf bean)... (note: everything up
to, and including, the c:set var=junkWhiteSpace is on one line)
%@ page contentType=application/pdf %%@ taglib prefix=c

There's actually a much more fundamental reason than all of the above (which are true nonetheless) -- JSP pages are not allowed to create binary output. They never call response.getOutputStream().

It is like using a screwdriver as a hammer because you like screwdrivers.

Re: [OT - JavaScript] Setting value on a html:select/
Disabled controls are not sent - that is an HTTP thing. You can use a hidden field or some other trick to get it there (or rely on the value of the radio button). Last I checked, the first form works only in IE. If you are writing only for IE, that's ok, but it is something to consider. The second works in almost any browser. Larry [EMAIL PROTECTED] 10/29/03 9:44 AM Been screwing around with this all morning, and can't seem to find an answer. I've got two radio buttons on a form. If the user clicks the second radio button, I need to force the value of a following html:select/ to a specific value, and disable the select. So, using JavaScript, on my radio button I fire an onclick event that run a real simple javascript function. In this function I've tried using document.formName.selectVar.value = default value // is accepted, but the default value isn't passed to my form bean document.formName.selectVar.option[0].selected = true // ditto document.formName.selectVar.option[0].value = default value // ditto document.formName.selectVar.option[0].isSelected = true// ditto JavaScript seems to accept all of these formats, but the setter method in my form bean for 'selectVar' is never getting called.

Doing it the way you describe will only work from a servlet. If that is ok, stop reading and do it that way. :-) A more general way would be to use a classloader instead. There are many good articles on how to do this (google for 'classloader resource'), but one simple way is this: InputStream is = getClass().getClassLoader(). getResourceAsStream(foo.xml); To do this, the resource foo.xml *must* be on your classpath. If it is in a package, you need to specify that in the call made to the getResourceAsStream() method. Also this cannot be done in a static context.

Next, set an environment variable CATALINA_OPTS to this: -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n Then start tomcat. Now, you can connect from netbeans: Debug Attach... Debugger Type: Default debugger (JPDA) Connector: SocketAttach Transport: dt_socket Host: localhost Port: 8000 If you have source versions of the jars, you can mount the directories (or jars) with the source and debug them too. For example, for jdk1.4, mount $JAVA_HOME/src.zip and you can debug all they way down to java.lang.Object if you are into that sort of thing. I usually unzip/unjar all source (java, tomcat, struts, jakarta-commons, etc...) into one directory tree, that way I can mount that one directory and debug everything. Another nice benefit of this approach is that you can run javadoc on that tree and have one place for all your javadocs... Larry [EMAIL PROTECTED] 05/15/02 03:27AM Hi World! I have got Struts 1.0.2 (particularly struts-example) running under NetBeans 3.3.1 (built-in Tomcat 3.2.1).
Re: I need help building tiles from src - please
Gee, I had the exact same problem at my house this weekend. ;-) The build for struts was trying to build tiles, but it looked like when using relative paths for my struts build, the tiles build looked in the wrong directories for supporting jars and puked. I changed one build.xml file and got one example to compile, then found the setting to NOT build the webapps. Once I turned that off, I got struts to compile, albeit without tiles. I suspect that if you used absolute paths that it would work, and hope that the next released build will work better with relative paths. I may spend some more time this week to try and get it going... Larry [EMAIL PROTECTED] 05/13/02 09:11AM Hi, I've been trying to build tiles and am struggling a bit. I downloaded and ran a build of 'jakarta-struts-1.1-b1-src' only to find that it doesn't automatically build tiles. When I finish building struts, I can see a contrib directory which contains a tiles subdirectory with the tiles source in it. When I read the build.xml notes, it says make sure this file is in the root of the struts-src directory. This is going to override the existing struts build.xml - which is surely not what we want. What is the best way to arrange things?
Re: How to productively use Netbeans and Struts?
This is how I use them (and ant with tomcat 4 instead of 3 now, but real similar setup on tomcat 3). I do not know that this is the *best* way, but it works pretty good for me. ;-) I mount the docRoot of my tomcat context in netbeans. When using 3.3.1, it creates a real useful project view for you (mounts all jars in WEB-INF/lib, etc). I am not sure, but this may require a build.xml in the context somewhere? :-/ Then I set up tomcat to allow remote debugging by setting the CATALINA_OPTS environment variable to: -Xdebug Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n Then I can use the remote debugger from netbeans: Debug Attach... Debugger Type: Default debugger (JPDA) Connector: SocketAttach Transport: dt_socket Host: localhost Port: 8000 I set my context to reload, so changes get reloaded by tomcat (no restarts!). Hope this helps, if you have questions, feel free to ask! Larry [EMAIL PROTECTED] 05/09/02 07:11AM So far I have been able to mount the struts.jar open the struts-example file and debug within Netbeans using the built in tomcat 3. Is this the best way to write software using Netbeans?
RE: Struts Beginner - Looking for *decent* documentation
The husted.com site has some good stuff. http://husted.com/struts/ Larry [EMAIL PROTECTED] 05/09/02 10:05PM I agree. The documentation is a little hard to follow. There are many other places that have docs and samplescheck out some of these links. http://jakarta.apache.org/struts/resources.html JM
RE: Question about select multiple='true' ...
I got it...I think.
There were two setters:
public void setUnt(int index, String unt) {
this.unt[index] = unt;
}
public void setUnt(String[] unt) {
this.unt = unt;
}
When the multi-select results got sent, they DID get sent as an array
(my bad). However, they got sent to the first setter, and since it was
not expecting an array, it puked and died.
After removing the first version, it now works.
So, now I am wondering if the right way to deal with this is to have
two properties: unt and untList where unt is the single item
indexed property and untList is the multiple item property?

OK, I have this html:

and these setters in my form bean:
public void setUnt(int index, String unt) {
this.unt[index] = unt;
}
public void setUnt(String[] unt) {
this.unt = unt;
}
But I get an IllegalArgumentException when I submit my page before
either method gets called.
What am I missing?
RE: Question about select multiple='true' ...
Second, a select sends only its value(s); you are (apparently)
expecting
the options' index position and text in your first mutator.
That was the question: How do those values get sent?
Clearly, they are not sent one at a time with an index.
Clearly, they are not sent all at once as an array.
Should I be watching for a carrier pigeon? :-)

Re: Form based security
Pete, You sound like you are on the same path I am. The last application used a custom model that was written in-house, based on jsp tags and struts action servlets. With the current project, we are using TC to provide the security (via LDAP to a Novell NDS tree). So far, the only surprise is that form-based authentication is a real stinker for development. When a class gets reloaded, the login information goes south, and you have to login again to refresh your page. Grrr. If you change to BASIC authentication, this is not a problem, but you have to be sure that if you are running over an untrusted network you are always going over SSL because the userid/password is sent as clear text with every request. One of the reasons we went with TC-based security instead of the roll-your-own variety was because now we can more easily harvest the web logs (that are automatically generated) for usage information using webtrends or other tools. Based on the logs (which contain the userid), we have a good idea of who uses what, when they use it, how often, what time of day, what day of the week or month, etc... We can then look at what users really use and focus our efforts instead of guessing based upon who complains the loudest. ;-) Larry [EMAIL PROTECTED] 04/29/02 02:12PM curious how other developers are approaching security. If you are using application server managed security, have you run into any limitations, or has it been a better approach than a custom solution? Thanks,

Re: Connection Pooling
You could use Oracle's connection pooling. You can use either the oci or thin client (in fact, the jdbc url is the same for pooling). The only difference I saw was that you get connections from the pool instead of from the driver manager. The pool class is oracle.jdbc.pool.OracleConnectionCacheImpl, and it implements the javax.sql.DataSource interface so you could (in theory, I have not tried this) swap out the pooling mechanism if needed with another pooling implementation. Larry [EMAIL PROTECTED] 02/01/02 12:31AM I've only taken a cursory look at Poolman and I'm a little unclear as to what benefits it provides. I'm using an Oracle server, and using the Oracle JDBC thin client to connect to it. The thin client has support for connection pooling. If I were to use Poolman, would it replace Oracle's thin client, or sit on top of it? What benefits are there to using Poolman? Or am I completely missing the point? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
