Just as an FYI, the file format for properties files is actually
documented, but the location is a little bit obscure -- check out the

RE: Struts on WebSphere

[Torben Norling]

Hi Andreas,
We use Websphere 3.5.2 on NT and it works ok for us.
There are no "Struts-specific" issues that I know about except for Websphere
being the product it is...

If you plan on using Struts with Websphere on Linux the issue is that there
is no WAS fixpack 2 for linux, this means there is no Servlet 2.2 / JSP 1.1
support that is required for using Struts 1.0. WAS Fixpack 3 should fix this
in mid februari.

We have at some point got into problems with reading the struts-config file
but in the end it always turn out to be the ing classloader(s) in
websphere that caused the problem...

Sorry, but I'm not to impressed with Websphere.

If you have an option to choose another appserver I would strongly recommend
that.

RE: Struts on WebSphere

[Hines, Bill]

Someone a while back said they had Struts working or almost working on WAS.
It seems that was before the 3.5.2 fixpack that brought WAS up to servlet
2.2 and JSP 1.1, so I don't know how that could be. Probably because it was
'early Struts' that still used JDK 1.1, servlet 2.1, and JSP 1.0. I'm
interested as well, if anyone has notes on this. I know that IBM is planning
to release WAS 4.0 this quarter, which is supposed to be fully J2EE 1.2
compliant, so we might just hold off until then. But I'd like to actually
play with Struts on our WAS 3.5.2 test box if that's possible.

The action attribute is used for two things:
* Create the destination hyperlink to submit to (which
  you don't need in this scenario)
* To look up the corresponding ActionMapping entry
  and, from there, determine what form bean to use.
  This information is used by all the nested field tags.

If you don't need either of these features, you probably don't need the
 tag.

I believe, session, since each visit to each page in sequence is a separate
request.

In both versions, the "scope" attribute of the  element

RE: Struts and MySQL

MySQL does support transaction (check out this article

You will need to set your table type to "BDB" to enable transaction support.
I am using mm.mysql JDBC driver version 2.0.3 which is JDBC 2.0 driver and
it is quite stable. I would recommend that you to upgrade to this version of

Digging into the GenericConnection class code teached me the following:

Consider a case where the Struts example application uses a conditional tag
outside the scope of an  tag -- the check for which type of
transaction is being performed at the top of "registration.jsp" in several
places, including when creating the  element:





If the name attribute were not entered here, I don't see how the tag could know
what bean you are referring to.

It would be feasible to make an assumption that, if you're inside a form, then
you must be talking about the form bean -- although that risks confusion as
well because the tag would behave quite differently depending on where it was
placed.

RE: Struts on WebSphere

[Bielby, Randy J.]

Bill,

We have the example app running on NT with WAS 3.5.2. I didn't configure it
myself but I don't think there was much special we had to do other than make
sure that you have the right jar in the classpath (xml parser etc) since WAS
puts xalan.jar and xml4j.jar in the classpath for you.  I think if you use
the WAR file to XML utility you can create an xml configuration file that
you can import into the admin console for the example app or whatever other
app you want to use.  There are two utilities you can use wartowebapp
(http://www-4.ibm.com/software/webservers/appserv/doc/v35/ae/infocenter/was/
040210.html) and wartoxmlconfig
(http://www-4.ibm.com/software/webservers/appserv/doc/v35/ae/infocenter/was/
060600020104.html).  I'm not sure which is the most appropriate to use (I
think wartoxmlconfig) but you can find them in the bin directory.  Also,
remember that if you are also using VAJ the WTE does NOT support servlet api
2.2, use the Tomcat test environment instead.

Missing message for key index.title

I grabbed the latest nightly build, recompiled struts, dropped
struts-example.war in the webapps dir, but when I try to run it I get the
above error. I noticed quite a few threads on this, but most pertaining to
the Orion server. I'm using Tomcat.

Everything was working with my 0.5 tree, but I decided to upgrade and here I
am. The properties file it is looking for in web.xml does exist, and there
is indeed an entry for index.title.

any suggestions ?

Request scope objects are retained across a *forward* but not across a
*redirect*.  The reason is that a redirect is actually a message sent back to
the browser, which then submits a second request to the new URL.  The request
attributes are not shared because it is not the same request any longer.

Session scope objects, on the other hand, would be retained across the
redirect.

I am forced to use struts 0.5. Hence I pulled back the upload package into

DiskMultipartRequestHandler (or whatever implementation is used) is created
inside of RequestUtils.populate(Object,String,String,HttpServletRequest).
The RequestUtils.populate method is called from
ActionServlet.processPopulate()


>What makes the handleRequest() to be called as the first method

handleRequest(HttpServletRequest request) is an interface method in
MultipartRequestHandler that is specified to be called on to handle
multipart requests.  "Handling" multipart requests consists of doing
whatever the implementation wants it to do.  The
DiskMultipartRequestHandler
reads the ServletInputStream and obtains form input entries and file input
entries.  It's called inside of RequestUtils.populate() soon after the
MultipartRequestHandler class is instantiated.

The Struts example application does something similar to this -- the only
difference is that I chose to use two different actions (/editSubscription.do
versus /saveSubscription.do) for the two distinct functions of populating the
form bean versus saving the results to the database.

RE: logic:greaterEqual tag (also logic:iterate with Arrays thread)

[Pete Black]

Does anybody know whether this will be the preferred method of accessing
bean methods using logic tags in Struts?

It seems a little confusing that you have to know the names of the bean you
are using when you use logic:xxx tags, but not with html:xxx tags.

If it counts for anything, my vote would be to keep the default case in all
the tags consistent - when there is no name parameter defined, the property
tag refers to the bean bound to the current action in struts-config.xml. It
makes things clean and magical like they should be.

Is the current behaviour set in stone for version 1?

ActionForward: scope of modifications?

[John Raley]

I didn't do a thorough walk through the source, but it appears that if I
modify an ActionForward returned from an ActionMapping passed to
Action.perform I am changing global state in struts.  Is this correct?
If so, I think this should be in the javadoc for ActionMapping, and
ActionForward should be cloneable or have a copy constructor.

Thanks,
John

Re: Is "request" shared across a redirect?

Certainly makes sense.  I was able to change to using forward and now I'm

Re: Is "request" shared across a redirect?

[Bear]

James,

A redirect causes the client to make a new request of the server. As such, 
the target of the redirect is a new request and will not share attributes 
with the previous request.

Re: Is "request" shared across a redirect?

[John Raley]

A redirect instructs the client to generate a new request, so by the time
foo.jsp is invoked the request containing the bean is gone.

Struts on WebSphere

[Gehmeyr Andreas]

Has anyone installed a current version of struts on WebSphere3.5.2? Any problems/hints?
Thanx,
Andreas

Re: Is "request" shared across a redirect?

[Jason Kitchen]

Requests are not preserved over a redirect because this generates a redirect
response back to the browser. The browser responds by requesting the URL provided
in the redirect response.

Request and response objects are preserved over forward because this is internal
to the webserver.

Is "request" shared across a redirect?

[James Howe]

I have two JSP pages which I want to have share a bean.  In the first JSP 
page I do something like this:

[...]



[...]

In "foo.jsp", I have code which looks like this:

[...]

Message not available





[...]

When I invoke the first page, I make the transition to the second page, but 
the bean property is never found.  I've debugged the code and it appears 
that the request object used by the second page does not have the attribute 
defined by the first page.  I guess I thought that objects put into the 
request scope were maintained across a redirection.  Was I wrong or am I 
just doing something stupid?

Thanks.

Re: WebLogic 6 & Example App

[John LeGassic]

Carl,
I was wondering if you could give me a hand.  I have been trying
to migrate a Struts 0.5 App that ran on weblogic 5.1sp6 to weblogic 6. 
Perhaps you could answer the following:


What version of struts are you using?


Did you upgrade Weblogic 6 to use the EJB 2.0 jar


In weblogic5.1 there needed to be a WebAppStartup.class, which I believe
modified the order in which classes where loaded.  Did you need this
class in weblogic 6?   If so how did you specify where to find
the class in weblogic 6?  Could you share your config.xml file?


Finally, could you share any other details that may be of use.

Any help you can provide would be appreciated.  Thanks!!!

IE4.0 / linked stylesheet problem?

[Ned Seagoon]

Hi all,

I hope you can really help me out here, I'm really stuck for ideas. I'm 
running Struts 28/1/01, tomcat 3.2.1 and IE 4 version 4.72.3110.8

I have just spotted a problem that does not replicate under IE 5 (which i 
have always used).

I have a jsp could be accessed by localhost:8080/test/showsomething.jsp . 
That jsp has the following



(have have tried with no directory and at root, still not working).

Now under IE 5, the site displays correctly with the stylesheets. If I 
access from IE 4, then the stylesheets are not loaded. However if I enter 
localhost:8080/test/site.css, I can access the stylesheet.

Other sites with css can be seen from this browser.

Is this a struts or tomcat issue do you think?

Cheers
Ned

Hi alI,

I am trying to implement paging for web application. The query may return
over thousand records and it is a bad idea to dump all of those to the
client. I was thinking to feed only 50 records at a time and have client to
click for next or previous page. We are using struts with EJBs. Our action

I appreciate any responses.

RE: Help: DiskMultipartRequestHandler

[Schachter, Michael]

>Where in the ActionServlet is the DiskMultipartRequestHandler class
>instantiated ?

DiskMultipartRequestHandler (or whatever implementation is used) is created
inside of RequestUtils.populate(Object,String,String,HttpServletRequest).
The RequestUtils.populate method is called from
ActionServlet.processPopulate()


>What makes the handleRequest() to be called as the first method
>automatically ? Who calls it ?

handleRequest(HttpServletRequest request) is an interface method in
MultipartRequestHandler that is specified to be called on to handle
multipart requests.  "Handling" multipart requests consists of doing
whatever the implementation wants it to do.  The DiskMultipartRequestHandler
reads the ServletInputStream and obtains form input entries and file input
entries.  It's called inside of RequestUtils.populate() soon after the
MultipartRequestHandler class is instantiated.

RE: Struts and MySQL

[Alix Jermyn]

I have been using mm.mysql-2.0.3 with the struts GenericDataSource for the
past fortnight without any problems, using the jRelationalFramework at
http://sourceforge.net/projects/jrf/  (you will have to apply the uncommited
MySQLDatabasePolicy patch as listed at
http://sourceforge.net/patch/?group_id=8796 and create any needed custom
ColumnSpec classes (pretty simple cut and paste job).

I am quite taken with jRelation; it does most of the work for you, but still
leaves you with quite a bit of flexibility and portability across most
serious databases.  If you are not going to use EJBs for data access, take a
look.
/alix


I've been using mm.mysql-2.0.2 - but checking <
http://mmmysql.sourceforge.net/ >. I see 2.0.4 is the latest stable
version as of 25-JAN. (The MySQL page is stale.)

I installed Resin last week, but had been using Tomcat 3.2 - and both

I just updated my MySQL version to 3.23 (declared "stable" as of

Struts installation notes - WebLogic 5.1

[rhayden]

I have put together the following install notes for WebLogic 5.1 based on my
experience over the past few weeks. Any comments or suggestions? I am
particularly disturbed by the fact that I can't get WL to deploy unzipped
web applications without including app-specific classes in the WL classpath!
Does anyone have another approach to this? Another problem I can't seem to
get around- Deployment of wars requires manually extracting the resource
file(s). Perhaps there is a way to get WL to find all files in the war (and
not just *.class)?

BTW- the builds for the past few nights have a problem with the lowsrc
property in class ImgTag (Thanks Carl for pointing out that problem with the
case in that method).


-Bob

~~

WEBLOGIC 5.1 (service pack 8)

(1) Obtain and install the Xerces XML parser (do not use the Sun reference
implementation). Put xerces.jar in your WebLogic system path.

(2) Obtain and unpack the Struts binary distribution (this procedure assumes
it was extracted to C:\jakarta-struts).

(3) Add an entry to weblogic.properties for each of the Struts web
applications that you would like to configure. For example, to make the
struts-example application available, add the following line to
weblogic.properties:

weblogic.httpd.webApp.strutsexample=c:/jakarta-struts/webapps/struts-example
.war

(4) You do not need to include struts.jar or any of the application specific
classes in the WebLogic classpath, since this will be done automatically
(unless deploying an unpacked web archive- see below).

(5) Start WebLogic server and point your web browser to the struts
application. For example, to connect to the example application added in
step 3:

http://localhost:7001/strutsexample

* This example application depends on the Struts specific resource file
ApplicationResources.properties to be present on the classpath. However,
WebLogic only extracts *.class files from the archive so this file will not
be found, resulting in an error the first time it is needed- something
similar to: javax.servlet.ServletException: runtime failure in custom tag
'message'. Steps 6 & 7 will need to be performed for this application, and
any other that relies on ApplicationResources.properties.

(6)  Extract ApplicationResources.properties from the *.war file, and
manually copy it to the respective package in the _tmp_war_ directory
WebLogic created for this application. Again referring to the struts-example
application, this would be:

c:\jakarta-struts\webapps\WEB-INF\_tmp_war_strutsexample

(7) Restart WebLogic. You will now be able to run the application:

http://localhost:7001/strutsexample


* The above steps should be followed for applications deployed as *.war
files. For unpacked web applications, configuration involves adding both
struts.jar and /WEB-INF/classes to the WebLogic classpath. For this reason,
I would suggest deploying applications as war files to WebLogic. However,
the same example application can be successfully deployed in extracted
format by modifying weblogic.properties (assuming the war was extracted to
directory webapps/struts-example):

weblogic.httpd.webApp.strutsexample=c:/jakarta-struts/webapps/struts-example
/

And starting WebLogic with the updated WebLogic classpath. For example:

c:\jdk1.3\bin\java -ms16m -mx64m -classpath
c:\weblogic\lib\weblogic510sp8boot.jar;C:\weblogic\classes\boot;c:\xerces\xe
rces.jar
-Dweblogic.class.path=c:\weblogic\lib\weblogic510sp8.jar;C:\weblogic\license
;C:\weblogic\classes;C:\weblogic\myserver\serverclasses;C:\weblogic\lib\webl

I have the same experience as Matthias with autocommit off. I simply

I think it should actually throw UnsupportedOperationException or

Ted, could you possibly be using Caucho Mysql driver?

Re: Struts and MySQL

Hi Ted,

thanks for the quick response. Pls see my comments below.

This is true. Here is my datasource config section (looks pretty much equivalent
to yours):

All I wanted to say is what version I am using: 1.2c (from
mm.mysql.jdbc-1.2c.tar.gz)

I have a mm-mysql.jar in my classpath, too. And as I already said, my datasource
config looks almost perfectly the same.

What I did in order to narrow down the error was a call to conn.getTypeMap() in
a separate (non truts test application). This call always throws an
AbstractMethodError exception.

Maybe you are using a different version of the MySQL driver? Maybe 2.0preX
(which is pre-release beta)?

Sorry....RE: Struts installation notes - example's setLocale on JRun

[Moore, Mark A]

Sorry for the screwy mail before.  Here is what I sent.

My project got hold of JRun 3 SP2 yesterday and noticed that this is a Known
Issue (e.g. Unfixed Bug) in the service pack.  I don't have the bug number
handy.  There is no news on when an SP3 might be available.  I had
complained about this a few weeks ago in the JRun support forum, but there
was no response from any Allaire folks.

  (703) 796-6014email: [EMAIL PROTECTED] Unfortunately, 
it appears that JRun has an implementation bug. 
The servlet container is supposed to do automatic type conversions when 
the data type of a custom tag property is something other than a 
String.  In this particular case, the "locale" property accepts a 
boolean value. 
The set of required conversions are in Table 2-4 on page 65 of the JSP 
1.1 specification.  Originally, it was not clear (in the spec) that 
these conversions applied to custom tag attributes, as well as 
, but this was cleared up in an errata to the spec 
that was published last April, at: 
    http://java.sun.com/products/jsp/errata_1_1_a_042800.html 

As a workaround on JRun, you can add a String setter for each non-String 
property, but this is not a good long term solution, because such a tag will 
not work on any other servlet engine (because the Java reflection code will 
see two setter methods, and therefore decide that neither of them is 
appropriate -- so the property will be considered read only).

db connection pool

[Andre Wittenburg]

Hello,

i just looked at the GenericDataSource and thought it would be a nice
feature to shrink the pool size when the connections are not needed
anymore. If you all agree, imho there should be two more values in the
dtd for the data-source and GenericDataSource. 
true/false
100

What you think?

RE: logic:greaterEqual tag

[Ted Husted]

> I don't have to specify, for example, , i can just say ..
shouldn't the logic tags follow this model by default?

I think here the logic tags are following the general bean-tag model by
default. 

In the case of the HTML tag there is an implicit, default
name="[formbean]" parameter to the  tags, which is then made
the default name parameter to the tags nested within the form. Of
course, you can override this in either case by supplying another name
parameter. 

I'm actually surprised that you were able to use the greaterEqual tag
without a name parameter. I hadn't realized the logic tags were
consulting the action mappings now.

Shouldn't this be implicit - i.e. whatever FormBean is associated with

This is how the html:text tags etc. work.

shouldn't
the logic tags follow this model by default?

Re: using logic:iterate with Arrays

See if adding 

name="myFormBean" 

as a parameter to the logic tag helps.

Hi there,

can anyone help me out with the syntax for dealing with iterating

my current code looks like:

the method getRecords() in my FormBean returns a String[] array, but i
get
this error:

java.lang.NullPointerException at
java.util.Hashtable.get(Hashtable.java,

It looks like Struts thinks it is trying to iterate over a Hashtable.
The

use
another type of object, rather than an Array?

Re: Struts and MySQL

[Ted Husted]

I've been using MySQL locally on Tomcat and Resin for some time without
any problem. 

MySQL doesn't support transactions, so I have to keep autocommit off.

I'm not sure what you are saying here. I have a recent mm-mysql.jar on
my classpath, and then use this datasource config, but that's it.
