Re: :80 in URL of Links generated in example app
I don't really understand you question, are trying to use struts with apache ? You have to know that struts will not work on the Apache server, you'll have to use Tomcat instead. The default port for Tomcat is 8080, so that you will have to type e.g. : http://localhost:8080/struts-example if you want to make it work on the 80 port you will have to change the server.xml file and change the value of the "port" parameter.

Re: :80 in URL of Links generated in example app
I'm running with Tomcat 3.2.1 and using mod_jk to work with Apache. Sorry for not making that clear before. I added .do to the JkMount for struts-example so the .do files are working but I'm finding I get thrown back to the logon screen whenever the link has the :80 appended to the base url. I'm using the just released beta binary version. I took a look at the source for BaseTag from the binary release and the source release and they are different. The source release doesn't append the :80 to the base URL but the binary source does. So, it looks like the two aren't in sync with each other. In a situation like this who would be contacted to get the newer version of BaseTag into the binary version? I've been meaning to compile from source so this will be my incentive to do that but I would think the source code should match. Agree?

servlet.log question
In the Struts example code wherever debug/log information is being printed to
the log, the code appears:
if (servlet.getDebug() = 1)
servlet.log("debug/log message");
I was wondering if that was advantageous over:
servlet.log("debug/log message", 1);
I am under the impression that the two samples work the same, and would prefer
to use the second, however I was wondering if there was some sort of
performance issue, etc . . .

RE: Beta 1 image tag bug
In the HTML spec, there are many tags which don't require an ending tag. The input tag is one such element. The XML-like self-closing tag is not part of the HTML spec. I've seen a lot of this with struts and other tools which use XML. Another example is the br tag which is often improperly specified as br/. Since it doesn't have an associated end tag, page authors often mistakingly specify this tag as br/. There are many more examples. So, the way Struts does this via html:image/ is correct. -Tom Tom Maccariella Sengen -Original Message- From: Denis Hanson [mailto:[EMAIL PROTECTED]] Sent: Monday, February 26, 2001 11:27 AM To: Struts-User Subject: Beta 1 image tag bug I just converted my project to the Beta 1 version of struts and encountered a problem with the html:image/ tag.

Re: What a jar file is needed?
Are you sure you have installed an XML parser? Make sure you download it first (http://java.sun.com/xml), and install the jar files (jaxp.jar, crimson.jar, xlan.jar) in C:\jdk1.3\jre\lib\ext (for JDK v1.3, for example). This will eliminate the need to modify CLASSPATH. Maya Muchnik wrote: Hi, I have tried to compile struts-example.

RE: html:text with value
I found the problem which was causing this. I was making a call to servlet.log in the getter method for that tag (and only that tag). I just wanted to verify when the getters were called in the overall sequence. I also discovered that putting a call to servlet.log in the getter methods for other tags, also causes this error. Wierd. Vic -Original Message- From: Fickes, Vic Sent: Sunday, February 25, 2001 3:04 PM To: [EMAIL PROTECTED] Subject: html:text with value Hi, I am experiencing a problem with the html:text tag. If I don't specify a value attribute for the text tag, I get an exception saying, "runtime failure in custom tag form" with no other useful information. This goes away if I specify a value attribute. But then I can't set the contents of the text in my Action.perform() processing, ie. the contents of the text tag are always set to the contents of the value attribute. I have a textarea tag right next to this with no value specified (so I can set the contents), but I don't get this error. My environment is WLS5.1SP8 with Struts v1b1 (but I have seen this in earlier versions of Struts, too.). Has anyone else ever seen this behavior, particularly those who are also using WebLogic?

Re: servlet.log question
Josh wrote:
In the Struts example code wherever debug/log information is being printed to
the log, the code appears:
if (servlet.getDebug() = 1)
servlet.log("debug/log message");
This is also my typical pattern throughout the Struts code itself.
I was wondering if that was advantageous over:
servlet.log("debug/log message", 1);
I am under the impression that the two samples work the same, and would prefer
to use the second, however I was wondering if there was some sort of
performance issue, etc . . .
If you do this as a method call, any expression required to calculate
the
debugging message will be performed, whether or not you ever really
write the log
message out. This can be pretty expensive if you are doing something
like this:
servlet.log("Name=" + name + " and value=" + value, 1);
which does a bunch of string concatenations. You don't mind paying the
price if
you are really doing the debugging output (because it's just for testing
anyway),
but you really do *not* want to spend the time doing the string
concatenations in
production. Using the "if" approach avoids that.
Thanks,

Re: hide a link or JSP's URL
Maya Muchnik wrote: Hi, How make a link or JSP URL "invisible" to a browser? I have read some chapter in a book, I know that this is possible. Is it possible with Struts? Is it some property "visible=true / false"? Another Craig knew the JavaScript trick for this one :-). The second question is about "input" parameter in "Action Mapping" section of struts-config.xml. For example, struts-example has no "input" for "Edit user registration", but has "forward" for "success". On the other hand, "A walking tour of the example application" (http://localhost:8080/struts-example/tour.htm) has both (paragraph "CheckLoginTag.java": I suspect this part of the walking tour was based on an older version of the example code. --- !-- Edit user registration -- action path="/editRegistration" type="org.apache.struts.example.EditRegistrationAction" name="registrationForm" scope="request" validate="false" input="/registration.jsp" forward name="success" path="/registration.jsp"/ /action -- What is right? The "official" version of the example (that is, the code that is actually executed when you run the example), does not have an "input" attribute on the "/editRegistration" action. The reasoning is this: the "/editRegistration" action is never used as the target of a form submit, so there is no concept of returning to an input form after a validation error. This action is invoked to "set up" a new form bean before transferring to "registration.jsp" for entry, so there is no need for input processing before it is invoked. One of the places that "/editRegistration.do" is referenced is on the main menu page -- it is the destination of the hyperlink for the "Edit your user registration profile". So, if we follow through on what happens when you run the app: (1) Log on and go to the main menu. (2) Click the hyperlink for "/editRegistration.do" (3) This action sets up a form bean, populated from your current user information. (4) This action returns a forward to the "success" page, registration.jsp (5) The registration page displays, accepts your input, and submits to the "/saveRegistration" action (6) This action has an input form declared, so the validation occurs. If there are any errors, returns to (5) with the error messages object created (7) If there are no errors, the save registration action is called. So, you should use an "input" attribute only on actions that actually accept an input form (and therefore might detect validation errors and need to return). Actions that don't do this do not need an "input" attribute. Maya Craig
Re: Beta 1 image tag bug
Tom Maccariella wrote: In the HTML spec, there are many tags which don't require an ending tag. The input tag is one such element. The XML-like self-closing tag is not part of the HTML spec. I've seen a lot of this with struts and other tools which use XML. Another example is the br tag which is often improperly specified as br/. Since it doesn't have an associated end tag, page authors often mistakingly specify this tag as br/. There are many more examples. So, the way Struts does this via html:image/ is correct. It doesn't need the closing "/", but it definitely needs a closing double quote on one of the attribute values. This will be fixed soon. -Tom Tom Maccariella Sengen Craig
Re: Base tag question
James Howe wrote: Is there some reason why the base tag defined in the HTML tag library doesn't let you specify the optional target attribute? I'm working with a frames based web application and I need to use both the href and target attributes. I know I could subclass the custom base tag, but before I do, I was wondering if there was any particular reason why the standard Struts base tag does let the user specify the target. I prefer not to support attributes that aren't in the official HTML 4.01 specs, and this is one of those. You're welcome to support it yourself in a subclass, however. Thanks. Craig

More seriously, that's why a lot of attention on the STRUTS-DEV list is being paid to building a unit test infrastructure for Struts 1.0. That way, we can catch the occasional slipup fairly quickly, and then (because tests are usually added to cover bugs that have been fixed) you can usually avoid regressions later on. Struts is pretty high quality (if I do say so myself :-), but not yet high enough. Jason Haase Craig PS: Just committed the one-line fix for this bug. It will be in tonight's nightly build.

Re: netscape 4.7x, session ids and struts
This is same problem I so awkwardly brought up this morning. The examples work on Netscape 6, Mozilla 0.7, Lynx and even IE5 but not on Netscape 4.72. Rick Gordon Maclean wrote: 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? Gordon Maclean -- * Gordon Maclean, Software Engineer, 303 497-8794 Nat'l Center for Atmospheric Research, Boulder CO USA *
