Struts and state information
I would like to keep session state soley in cookies so I can use round robin HTTP load balancing versus sticky load balancing(sticky load balancing as in all requests are directed at a specific web server for a given user. I read Professional JSP, perused this mailing list and looked on the web and nothing really elaborates on where the state is stored by default. I see how the html:link /html:link directive is translated into a href=http://...;jsessionid=X/a but where does it get X and where does it store the session information related to X? Does it rely on the jsession ID being passed around in URLs then keep the associated session information cached on the server? So if you have multiple servers you will need to use sticky load balancing to make sure users only use one webserver? What options are there in case I want to keep all session state in cookies? That is, ideally, I would generate an encrypted cookie w/ CRC containing the logged in username and minimal information about the user. And I would like to do this within the confines of Struts. Thanks for any help and I aplogize if this is a redundant question. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Help needed uploading files
Hello, I know this has been discussed before but the struts site seems to be playing up and I cant get into it to search the list. Anyway I am having problems getting files to upload to my server. The problem I have is when I read from the InputStream opened from the Request I get -1. In other words there is nothing to read. Is there anything I have to configure with Struts so that the files in the HTML page are uploaded properly. At the moment it seems as if they are not arriving correctly to the server. (I have ENCTYPE set to multipart etc). Thanks. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Executing code before each action
Hello, I have a piece of code than I need to execute before each action (it checks which country the user is in the then sets a session variable). I want to execute this before each action so that if a user bookmarks a page and returns without entering through the front door I still have the session variable. What is the best way of doing this. I have thought about using the RequestProcesser but as I understood it that is for changing request behaviour rather than this type of thing. Thanks in advance.

RE: can't register struts-config dtd on tomcat 4.0.3 (1.4 LE) - P roxy problems?
I'm really strecthing here, but:
* I was under the impression that it would use the dtd from the
struts.jar... are you using the v1.1 JAR in the webapp? Is there a problem
with the way 1.1 works, because I get this for v1.0:

* It is using crimson, but I didn't think that was what was included with
jdk1.4 (I could be wrong, I don't recall off-hand). If that's the case there
may be some sort of conflict, but there shouldn't be and it doesn't explain
the error.
* Have you tried using a small java program with a URLConnection to see what
happens when getting the URL? That'll affirm Java's network is at least
working correctly.

Proxy problems?
Are you behind a proxy? If so, you'll need to make sure that the JVM
knows about it before ActionServlet starts trying to read the DTD. One
way of doing this would be to subclass ActionServlet and override the
init method to something like this:
public class ProxyActionServlet extends ActionServlet
{
public void init(ServletConfig config)
{
System.setProperty (http.proxyHost,proxyserver);
System.setProperty (http.proxyPort,proxyport);
System.setProperty (https.proxyHost,secureproxy);
System.setProperty (https.proxyPort,secureproxyport);
System.setProperty (http.proxyUserName,username);
System.setProperty (http.proxyPassword,password);
super.init(config);
}
}
(I've typed this from memory so it may not work if you just cut and
paste). Then you'll need to make sure your web.xml file points to your
new class.

RE: Forward after check-login
I actually extended ActionServlet and intercept each request. From there, I can check whether we are restricting certain paths, then check the login cookie for the necessary permissions. If they haven't logged in, I forward to the login page with the requested URL in an attribute. This might not be the best approach. Can anyone suggest a better way while still having it in the controller? Extending ActionServlet poses problems for later if we start using Tiles with definitions when struts 1.1 is released. Is there a way to plugin to the action servlet at the doPost/doGet level as I currently do without extending it? Whatever the case, this code should certainly reside in the controller, not in a tag which is processed in the view because whatever the action is doing, it has already processed it before checking auth. - Brett -Original Message- From: Andy Timm [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 24 April 2002 2:13 AM To: [EMAIL PROTECTED] Subject: Forward after check-login I have some pages which require a user to be logged in and some which do not.

RE: Struts vs EJB, thoughts?
I prefer apples to oranges because they don't take their name from their colour. FYI, we use Struts with EJBs. EJBs are the M of MVC, Struts is the VC. There is little to no overlap. If you don't need the container support provided for EJBs (remote invocation, pooling, transactions, etc), then you use plain JBs as the M and struts as the VC. (That may be simplifying it somewhat, but you get my drift).

Not that I am looking for a job (I am not), I have been working with struts for the last 4 months and don't mind it. I see it as a poor mans EJB. I have no EJB experience but I don't think transitioning over to EJB after working with struts as a big deal. After all, they both act on server-side beans. Yeah, EJB has entity beans and session beans but you can easily simulate both of those types of beans using JSP/Struts/tomcat. Since there's a gazillion people on the planet now that know how to program in Java, getting an EJB position will be next to impossible (I guess) if you don't have EJB experience. Companies now have so many available Java programmers to pick and choose from and are in a position to require salary cuts for existing Java programmers on staff due to the plethoria of Java developers available to work who would be willing to work for less$Being a Java programmer is no longer an elite skill. Now it's as common as coding in Cobol once was :-( I have already read about the salaries of Java programmers declining and I expect the trend to continue due to the bad economy and the oversupply of qualified Java programmers in the market place. This is why so many companies can now demand specific product experience with Java (ie, if you don't have 1 year of Bea Weblogic experience, see you later!! Next person please...)... SO back to the Struts vs EJB issue: If one is comfortable with struts, how much more difficult would EJB be to get comfortable with? Also, seems like Struts is more useful for smaller companies and EJB is more suitable for large corporations.

RE: Hidden Field in a form. Do I use struts taglib or vanilla ht ml?
That's an interesting design decision. I have always had a form bean and
then another bean containing the actual data. The action copies it across,
processes it, and stores it.
The reason I'd do it that way is that I imagine the message is a business
class, and you don't really want you model polluted by extending an
ActionForm. Maybe I've been living in OOAD land too long though ;)
This can trip you up though - at least once I have added the form element,
added it to the bean, added it to the form bean, and forgetten to do the
setter in the action :) The way around that is probably a function in the
form bean that says fill my business class and fill from a business
class. Actually, I might put that in my todo list :D

And the hidden field is action=sendMessage and I didn't think that

I'm not talking about ActionForm validation, but rather the situation where an Action determines there is a error (ie either directly itself or via an exception from a business object). What is recommended approach with struts? - use of servlet errorpage specified in Web.xml? (not sure how this works yet, still have to find good doco) - use of struts errorpage as GLOBAL FORWARD to JSP which assumes maybe a ERROR_MESSAGE in request scope? - incorporate use of struts validation error infrastruture somehow? (eg re-use ActionErrors perhaps)? - would creating an ActionError in the Action itself and forwarding back to the original JSP page be possible in the case where there is not normally form validation on this page. ie leverage off ability to put html:errors/ in JSP just to handle presentation of backend errors (ie not formbean validation errors). I'm assuming the general approach overall is to throw business logic errors up the chain until hitting the Action classes so one may then present an appropriate error message to the user (via one of the approaches above?). cheers Greg _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: All the jar files cann't be read
Hi Lily,
I'm not sure which version of Tomcat you are using, but you need to read up
a bit on webapps, because it seems that the JSP's are not being handled by
Tomcat (perhaps Apache) or for some reason are being served as static files.
Tomcat 4 has some good documentation on how to set up a web application:
(should apply to 3 too). Sorry, can't send the link - jakarta.apache.org is
down :(
As for struts.jar, there is a doc on the struts site - probably in the FAQ
or kickstart FAQ, about where struts.jar can and can't be. I think it pretty
much says must be in web application's classpath - and nothing else. So
you can't put it in the CLASSPATH variable, jre/ext/lib, or tomcat's common
lib directory - that will make it available to Tomcat, other Java classes,
and other webapps, which will make things break.
Can I suggest you try getting the examples up and running first, then use
them as a model for your own system? That's what I found easiest.
Cheers,
Brett

Subject: RE: All the jar files cann't be read
I put the struts.jar file in that folder and put it into my classpath.
Maybe that is the reason why it shows that path. May I ask where I could
config this ?
By the way, I still got blank page but if I click view source, I can see
all the jsp code is there, which means that all the taglib or related lib
files could not be found or linked. I think I put all the lib files in
right place. May I ask where I could config this path other than at the top
of each JSP page ?
Tons of thanks.

My guess is that it got corrupted in the download, or perhaps because you

Can you unjar the struts.jar file manually into a temp dir to check it is

/processTrivia.do is in fact "root-slash-processTrivia" - but in relation to your current context. If your webapp is named sports, then it will have to be /sports/processTrivia.do How you get around this depends on your servlet container.

RE: ~~ Confusion with triggering an Action ~~
SoD:/myapp/WEB-INF/web.xml contains the action servlet
configuration. In that case /processTrivia.do should be the same as http://www.server.com/processTrivia.do,
because defaultWebApp maps to /
I'm
not sure about this one - perhaps Struts thinks your webapp is named sports.
Perhaps it is a weblogic problem.
I have
never had to reference anything other than the mapped name, unless I use a
"normal" href or form.
eg:
mapping: /logon in webapp "project"
html:form action='/logon'
but
form action="/project/logon.do"
Sorry,
I don't think I've been much help in the end :)

Subject: RE: ~~ Confusion with

I'm talking about webapps from the perspective of the servlet
specification. I don't think it's the same thing. (Think WAR files,
WEB-INF subdirectories)
Some servlet containers don't support/require this structure so
you may not be using them (eg older WebLogic).
What container/servlet spec.are you
using?
Cheers,
Brett

My default web application is not
"/sports", but rather just "localhost". If the site was live the
web app would be "http://www.mysite.com", and I would
be in the "/sports" directory. What can I do to get the behavior

/processTrivia.do is in fact "root-slash-processTrivia" - but
in relation to your current context. If your webapp is named sports,
then it will have to be /sports/processTrivia.do
How you get around this depends on your servlet container. In
Tomcat 4, you could make sports the default webapp, so
/processTrivia.do would go to the sports webapp. Other containers
probably have a similar method. However, I don't recommend any of
these, especially if you have multiple web
applications.

RE: tomcat 4.0 and struts problem
Title: RE: tomcat 4.0 and struts problem Hi, There was a similar problem discussed last week. My solution at the time was similar, and a bit dodgy :) I've just read the Tomcat 4 Class Loader HOWTO today and that explains the problems - as you've said its all to do with XML parsers. I think the suggestion from them is to move crimson and jaxp to $CATALINE_HOME/common/lib from jasper/lib, and not to put anything in your WEB-INF/lib directory. If you need Xerces 1.3+ instead, remove crimson jaxp from jasper/lib and put Xerces in common/lib (not WEB-INF/lib). I'm about to see if it fixes my struts mapping problems, and repost if not.

RE: Struts DB example
Title: RE: Struts DB example Castor has a mailing list you can subscribe to from http://www.exolab.org. The examples it comes with are quite good, and the list will be helpful in getting them configured for you. As far as using it with Struts (as I do), I've placed a wrapper around the persistence mechanism and retrieving/updating the business objects from my action classes, then calling methods on them. This is because most of the actions are simple and there was no need to shadow business classes with a data object.

Error: MAPPING configuration error for request URI
Title: Error: MAPPING configuration error for request URI Hi, I'm getting this error out of either struts or Tomcat. I'm a bit confused - the number of them (13) at a time, matches the number of action mappings I have, so it appears to be Struts related, but grepping the source doesn't reveal it. It isn't an exception - just a message like so: 2001-10-04 17:33:11 StandardHost[localhost]: MAPPING configuration error for request URI x13 I only noticed after introducing Xerces as the parser instead of Crimson/JAXP - this is a requirement of Castor (just using Xerces in WEB-INF/lib causes some other problems). It isn't critical - it doesn't actually cause anything to break as far as I can see, but I'd prefer to resolve it to make sure. I've found nothing on either web or the mailing list archives for struts or tomcat to see what this might be caused by. Cheers, Brett

RE: Struts DB example
Title: RE: Struts DB example The struts example struts-config.xml file has an example of how to create a connection pool. However, from what I now understand that is deprecated. The struts-documentation webapp does have details about it though if you are interested. I thought there was a struts taglib example that shows how to use the JDBC features from JSP pages, but I think I was mistaken there - it must be in the commons project. That being the case this isn't really a struts issue - you should look at the jakarta-commons (it has DB connection pooling with good examples, although it isn't really up to a release, you'll have to check out the CVS). Specific database examples will depend on which database you use, and which JDBC driver you use, and anything else you choose to layer on that (app server, connection pooling, etc.). You should consult those sources and the web for more examples.

How do you load information into a bean that your form uses before displaying it?
I have a struts html:form which uses a struts Form bean. I'd like to read data from a database and use that data as the default data for the form. What is the best way to do this? Read the data and set the value parameter of the html:text html:select and html:checkbox tags? Load the data into a Form bean and use that bean for the form? I'm not sure how to do either of these options or if there is a third better way to do it? Thanks, Brad
Null PointerException when run with Apache/SSL/Tomcat
We are getting a NullPionterException which seems to originate from the the struts-html tag libraries. The error only occurs when we run Struts with Tomcat/Apache and SSL. If we bypass SSL and just go through Apache (port 80) we do not see the error. Has anyone else seen this problem when running Struts through SSL? Any suggestions would be appreciated. The error message is shown below. Thanks in advance for your help.

still not getting struts to work yet with Tomcat 3.2.1
Hello,
I've been trying for awhile to get my own version of the 'logon' example
to work. I've done everything essentially the exact same as the struts
example, except using 'login' where I saw 'logon'.
Upon starting up Tomcat, there is a bunch of output generated. After
reading this output, it seems that my action classes and action mappings
are not getting set up in the servlet context, since I do not see any
output - though I do see all the struts example servlet contexts getting
setup. For example: 'ActionServlet.addMapping(...)'.
I think the problem might be related to resolving the DTD entity in my
struts-config.xml file. Here is a snippet for the output I receive
after staring Tomcat. Has anyone seen this problem at all. I would
appreciate any help.
Thanks,
Brett Procek

You are correct, my ActionServlet is not starting up property. I looked
at the output and I listed some of it below.
For some odd reason Struts cannot resolve a certain DTD that it needs.
Please take a quick look.

Another bean:iterate question
I've been working on this bean:iterate ... problem for some time now. I
finally had to use a scriplet to get it to work. I am trying to get a list
of FieldTypes from a record controller (PrimaryServer below) which implement
an AbstractField object (this may be the entire problem ... let me know if
Abstract objects will cause problems). The controller has a method called
getFieldList which returns an Iterator of these AbstractField objects. I
then want to get the name of each field using the property getFielName().
The following is a snippet of my Jsp page. Tomcat always returns with an
error saying it "can't find bean 'field' in scope null".
logic:iterate id="field" name="PrimaryServer" property="fieldList"
type="com.iic.dbsync.IntField"
tr
td align="center" jsp:getProperty name="PrimaryServer"
property="fieldList"/
bean:write name="field" property="fielName"/ /td
td html:text property="field2" size="100" //td
/tr
/logic:iterate
Here is the scriplet that I wrote to finally get the results that I wanted.
% Iterator iter = PrimaryServer.getFieldList();
while( iter.hasNext() ) {
AbstractField field = (AbstractField) iter.next();
String fieldName = field.getFieldName();
%
tr
td align="center" %=fieldName% /td
td html:text property="field2" size="100" //td
/tr
%}
%
The iterator tag still trips me up from time to time. If anyone has any
suggestions I would appreciate them. I have enjoyed reading the previous
postings concerning the iterator tag.
Thanks again,
Brett
FormAction Bean for dynamically created forms
What is the best way to develop a FormAction bean for HTML forms that are dynamically generated? In other words, the FormAction bean won't know the parameters names of the form until runtime. For example, if I wanted to process HTML forms for relational database tables dynamically. Each input element could represent a column in the table. I have a Record class that contains a HashTable of the fields for a particular table. The Record class can be used to verify that the submitted values are correct for each field, but I can't have a static FormAction bean that knows every form paramter. Any suggestions would be greatly appreciated. Thanks in advance. Brett

Anyway -- the only way to get around the issue you are encountering is to take out the following line in your web.xml: load-on-startup1/load-on-startup Now as a consequence of doing this you will need to follow these two steps every time you restart your weblogic instance: 1. Load a jsp page through your browser before doing anything else (especially a post). This fixes the classloader problem with weblogic 5.1. 2. Next, load the ActionServlet by posting to an action class. This will also load your application.properties.
