JDBC Connection Pooling
Hi there, I'm currently trying to use the connection pool that comes with Struts but I have a problem with the spec in the Struts config file. The Bean simply doesn't show up in the servlet context (neither the default value nor my own key). When establishing the the connection pool by hand everything works fine. But when I try to access it in my initialization servelt (which is a subclass of the ActionServelt) via the config spec it don't. Any ideas what I may be missing? Regards Jürgen

I get the impression this is a dead race. Suppose XYZ puts a lot of effort in it and can get their product to be 99.9% compatible with TC 3.2. Does that mean they can do it again later (for 4.x)? I just don't think so. (sounds as if I'm talking about OS/2) Would'nt it (for us in need of Struts) be much smarter to avoid such problems and setup TC in front of our EJB-container? By the way, how do you judge the advances of running SE and EJB-container in the same VM compared to a) running on seperate VM's and b) running on separate machines? I can't express how glad I would be to see a discussion of that. Thanks.

Re: JDBC Connection Pooling
You can access the pool this way: GenericDataSource ds = (GenericDataSource) servlet.findDataSource(null); which I clipped from a working Action.perform method. -Ted. *** REPLY SEPARATOR *** On 1/23/2001 at 10:04 AM Lind Jürgen wrote: Hi there, I'm currently trying to use the connection pool that comes with Struts but I have a problem with the spec in the Struts config file.

Retreiving multiple values from SELECT boxes
I need to know how to retreive multiple values from a HTML select box using struts. So far I have set-up the SELECT box to allow multiple selects. On submission of the HTML form the values of the SELECT box are submitted in the request as an array of strings. However the bean setter method does not seem to be executed correctly as the required property is only set to the first element in the string array. I have stepped through the code and it seems to go wrong in the BeanUtils.populate() method were the incoming parameters are not properly recorded and sent to the property setter method. Has anybody come across similar problems ? Any feedback would be appreciated Regards Kevin
Capturing stderr to a file
Hi Struts Users, I've just installed a Tomcat / struts / JDBC application (standalone Tomcat on NT 4) and am working my way through porting it to talk to Oracle (original sample was PostgreSQL).. I've got it talking to the database OK, however the port has caused lots of type casting problems (it appears all my data gets returned as String from Oracle, however the original code seemed to get it back correctly). My biggest problem in finding these problems is that Tomcat is dumping STDERR to the terminal which scrolls away irretrievably, and I can't seem to get it to re-direct anywhere else - I've tried '2>filename' within tomcat.bat on the start command and have also tried setting it in the tomcat.properties and wrapper.properties files (changes in both these files seem ineffective). Any ideas ? Regards, Don Elliott [EMAIL PROTECTED]
FormTag problem
Having looked at the source code for the FormTag it appears that there is no
way to use it with an ActionMapping whose path contains a forward-slash
(other than at the start) because everything before the last one is removed
before looking up the ActionMapping. Why is this? It doesn't seem to me to
be the correct thing to do.

Struts and Weblogic 6.0

Is there an intention to make the example app work on WLS 6.0 and are there any aspects of struts that will not work on WLS 6.0 as a result of the serialization issues (and where are we with these too!). What is the situation with the change of the properties to use XML, properties files and database for storing internationalised strings?

Re: Struts and Weblogic 6.0
Hi, I'm currently buzy to migrate an application working on Tomcat to Weblogic 6.0 The problems with the PropertyMessageRessource class is not yet solved, but Craig confirmed me some days ago that he was working on it. Anyway, even if that problem still exist, it is possible to use Struts with webLogic 6.0, by doing the small modifications in MessageRessourceFactory ( it must be Serializable and de setPrintWriter must initialize the printWriter to null ). Otherwise I didn't had others problems ( I don't really know about the datasource problem, since I'm using an EJB implementation). except for small context path problems.

Tomcat, like any piece of software, has its own bugs, but a very large amount of attention is placed on ensuring that Tomcat is as spec compliant as it can be. Other platform providers decide for themselves how important that is to them. Pretty much all the container providers are represented in the expert group that *defines* those specs, so they don't have a lot of excuse IMHO not implement the requirements. >From a Struts perspective, we must absolutely stay within conformance to the specs, and not rely on the quirks of any particular server platform. > > Would'nt it (for us in need of Struts) be much smarter to avoid > such problems and setup TC in front of our EJB-container? > This is certainly possible, but you pay the (performance) price of having to do your EJB calls across network sockets (even if the EJB server is on the same machine).

Among the disadvantages of same-VM are: * Single point of failure (if the VM crashes, you lose everything) * Scalability (one mongo machine for everything versus being able to distribute and grow the front end or the back end independently as needed).

Locale and struts:message tag
I'm trying to display russian characters using the tag against an existing resource bundle. The resource bundle is being used by a working Swing application. The strings are displayed correctly in my Struts app for english, but for some reason when I set my locale and language to russian in the Web client, the messages are comming up in like ??? ?? ? . However, iIt appears that the number of spaces and ?s coorrelate to the actual characters in the resource file. I'm new to localization issues so please forgive my ignorance, but I suspect this may have something to do with encoding? I do know that I am able to view another page that cotains russian (cyrllic) characters. I'm not sure what I'm missing. Any advice would be most appreciated. Thanks. ;) Scott

That is because they are created, as part of the build process, from the files in the "src/doc" directory (such as "struts-bean.xml"). When you run the build, they are placed in the "lib" directory underneath your build destination.

RE: Struts and Weblogic 6.0
After seeing the talk about the API changes, I just downloaded the latest nightly build (01-23 binary version) and tried to deploy the example application to WebLogic 5.1 but it failed miserably with all kinds of XML related errors. I also tried to run the example app on JRun, but this failed as well (but with minor errors when JSP compiling- related to passing a string into the setLocale(), setFilter() perhaps also due to XML parsing?) Anyway, Struts 0.5 works for me on WL5.1 now on both of my development PCs so I am going to have to use this for now since I don't have time to figure out how to make the 1.0 build work. Hopefully this is as simple as suggested in the previous emails (I looked back a few weeks at the various threads). Or better yet, maybe my problem is just with my XML parser (I am using jaxp1.0.1). If anyone has successfully deployed the Struts v1.0 example application on WL5.1 please let me know... I may experiment some more with this next week.

set methods in ActionForm
I have two questions related with the set methods in any of the Form
class, such as MyActionForm.
1. It seems to me that if we use a form with POST method, the
corresponding "set" method will be called as it should be. What I want
to confirm is that if I have the URL with query string, does the
parameter specified overthere also cause the "set" to be called? For
example, I have the URL: http://.../action?name=value And in the
MyActionForm.java, I have the method:
public void setName(String name) {name = value;}
My experiment shows that when I clicked the URL, setName got called.
2. My second question is that I found the "set" method did not got
called if the length of the "keyword" is 2. For example, in the above
example, if "name" is "aT" and I have the "set" method,
public void setAT(String aT) {aT = value;}
The "setAT" does not got called.
Thank you for the help,

Any way to do includes in struts-config.xml
Is there a way within struts-config.xml to include data from external xml's. This way struts-config.xml does not get large and so the mappings can be managed in separate files. Our app has many optional componets, and it would be nice to be able to just do includes in the struts-config of the pieces.
Off Topic:: How do detect if user is still using your web application?
Hi This is a fundamental problem facing all web applications. Due to the asynchronous nature of Web pages, it is almost impossible to establish if the user is still "using" the application. In the client/server world. the user session terminates/disconnects when they close the application. How do you implement this for web session? My application creates a new session when the users log on, connects them to their database and store their database connection handle to their session. The problem is that I do not know when to terminate their database connection. At present, my application terminates their connection when their session times out, when they click on the logout button (which usually never happens) or when the application gets shutdown. I would be interested hear how people handles this especially if STRUTS have any mechanism to cater for this type of situation. TIA Michael Mok www.webappcabaret.com/teatimej

I imagine you really meant:
private String name;
public void setName(String name) {this.name = name;}
right?

Yes -- the controller servlet sees that the field name (from the form) matches
the property name (from the bean), once you apply the JavaBeans design patterns
for method names. See the JavaBeans spec for more details.

That's because this spelling does not match the required design pattern, so the
controller servlet (actually, it is the Java introspector that is used to ask a
bean class what it's property setter methods are) does not recognize this as a
property.

RE: how to change the window target in a JSP file?
Title: Deploying Struts on iPlanet 4.1 - any successes?
Hi
James,
You might need some heavy duty JavaScript
for this one but here it goes. Make sure you have refernece to the window
you want to optionally load within a hidden frame of window A (form submitting
window). When you submit the page, pull back the default page to
display in window A and if you need to populate window B then store the
contents of window B in Javascript in window A. When the default page
loads in window A use the window reference in the hidden frame of window A to
dynamically rewrite the contents of window B using docuemnt.open(),
document.write ("HTML to Populate other window that you got from foo.jsp"), and
document.close() to commit the changes.
Good
Luck,
Abraham

Deploy WAR file with Weblogic 510 sp8 on Solaris 7
I am able to deploy my WAR file with an un-jarred fashion. However, I wasn't able to deploy my WAR file as it is. My WAR file consists of a set of gif, xml, jsp, jar, css, so, and js files. Under WEB-INF\lib folder, it contains a set of jar files. Under WEB-INF\lib\solaris, it contains a set of library files. When I deploy the WAR file, I expected to see the set of .jar and .so files under WEB-INF\_tmp_war_abc\lib and WEB-INF\_tmp_war_abc\lib\solaris folder (where abc is my context name). Instead, I only see the .jar files under WEB-INF\_tmp_war_abc. In a result, some of my servlets and functions could not be found. Any idea will be appreciated. Thanks, Teresa

In regards to WL6, although this may not fix anyones particular problems, we noticed one thing with the beta version we have. Anyting in the /WEB-INF/lib dir does not automatically become part of the classpath. I assume this is (or was) a bug with WL6. It works fine in Orion App Server.

RE: Off Topic:: How do detect if user is still using your web application?
First of all..NEVER I repeate NEVER store a database connection handle in
the HttpSession. This is a VERY bad thing to do. If your site grows..you can
forget about scalability. You'll be paying out the rear for licenses if you
have 1000's of users hit your site. At any rate, the first thing you need to
do is institue a connection pool for database connections. Second, have your
action class grab a connection at the start from this pool, then return it
at the end. Also, make sure you wrap everything up in a try..catch block and
catch Exception or better, Throwable and make sure you ALWAYS return the
connection (infact..put a finally{} block in that always returns the
connection.
Now, once that is done, here is the only thought I have on making sure a
session is terminated if they are done.
Now, write a javascript routine that submits a form or href link (or use an
applet on your site and have the javascript call the applet which then calls
through RMI or something to the server) to free any resources and invalidate
the session.
I am not sure how feasible this is. The only way I would really do this is
to have your entire site wrapped up into a two frame setup, with the first
frame being a hidden one with no size to it. Load an html page that loads in
the javascript that does the above..so that if they leave your site all
together, that little routine is called which will then close their session
info on the server. However, if you can't use frames in this manner, I am
not quite sure the above will work. The main reason is..each and every time
they go off of one page..even if they are going to another page on your
site, that javascript routine will be fired. I suppose you can have all
links and for submissions set a flag if they are clicked that is then
checked by that routine. If the flag is set, it jumps to the link clicked.
If the flag is not set, it submits the post to close the session (indicating
they are leaving your site).
Let us know what you come up with.

RE: Deploy WAR file with Weblogic 510 sp8 on Solaris 7
I have the same problem with WL5.1 well sort of. In my case, WL only deploys *.class files, so struts failed because it needed the applicationResources.properties and it could not be found. In your case, perhaps WL is ignoring the SO files. This seems to be an issue with WL, as there are posts on newsgroups.bea.com related to this but I could not find a solution... I even posted this to the install group but no reply :( I also find deploying to WL particularly annoying (compared to JRun or Tomcat) because it does not add WEB-INF/lib or WEB-INF/classes to the classpath- you have to do this manually. Apparently it does automatically add the path for *.wars, but then then it only deploys *.class files... argh!!! -Bob -Original Message-From: Yu, Teresa [mailto:[EMAIL PROTECTED]]Sent: Tuesday, January 23, 2001 9:31 PMTo: '[EMAIL PROTECTED]'Subject: RE: Deploy WAR file with Weblogic 510 sp8 on Solaris 7 I have all of JAR files under "WEB-INF/lib".

RE: Struts and Weblogic 6.0
This is the functionality in 5.1 as well... must be a WL "feature" :) The classpath does seem to get included for a *.war, but then there are other issues (see my other post). Do you have Struts 1.0 working on WL6? If so, then what is your configuration? i.e. what XML parser do you use? can you do a wlconfig > config.txt and attach the file (so I can see the contents and order of your WL classpath)?

Re: Struts and Weblogic 6.0
Hi, There is already a XML parser included in the weblogic.jar file, so you don't have to add any other library in it. Personally, I didn't have to change anything in the classpath to make it work, the only thing I had to do is to copy the the struts. jar file under the WEB-INF/lib directory in my War file. One last thing, is, don't put the struts library in your classpath, it gave me a lot of problems. Thierry Thierry Cools Senior Java Developer S1 Brussels Kleine Kloosterstraat, 23 1932 st.

HtmlTag - locale
Hi,
I admit, I am a STRUTS-beginner and anyway not familiar with mailing lists
:-), but is it correct that in the HtmlTag the attribute locale is a boolean
?
My IPLANET6.0-Jsp-Engine tries to set a STRING and fails compiling my
JSP-page.
I thought every attribute in a Tag should be a STRING !?

HtmlTag:
protected boolean locale = false;
public boolean getLocale() {
return (locale);
}
public void setLocale(boolean locale) {
this.locale = locale;
}

logic:iterate and form controls, revisited
Hi all, I recently ran in to a need to perform a task that's been discussed on this list at least a couple of times since I've subscribed. Unfortunately, an actual way to make it work was only described once, and that approach was unappealing. The problem is that I would like to construct a JSP with an HTML FORM that has a series of similar lines, using logic:iterate. The fundamental problem is that the various struts-form tags use the same name for all instances of a control in a given "column". This means that struts can't automatically shove the posted data back into the form bean for you (at least correctly!). The one approach to solving this that I saw (over the last two months or so) was by Chandan Kulkarni. If you want to go back and check it out, here are the headers: Date: Fri, 5 Jan 2001 07:44:11 -0500 To: <[EMAIL PROTECTED]>, "Mishkin Berteig" <[EMAIL PROTECTED]> From: "Chandan Kulkarni" <[EMAIL PROTECTED]> Cc: "Chandan Kulkarni" <[EMAIL PROTECTED]> Subject: Re: Help: and form input fields Message-ID: <002f01c07715$3520bb50$[EMAIL PROTECTED]> This approach involves: (a) using raw HTML form tags, e.g., instead of . (b) constructing the value of the "name" and "value" attributes for the HTML form tags using JSP expression substitution - <%= %>. (c) Changing public static void populate(Object, String, String, HttpServletRequest) in BeanUtils.java to comment out the code which discards any subscript expression that might be present in the name part of a posted name/value pair. (d) Inserting code into public static void populate(Object, HashTable) in BeanUtils.java to look for an indexed or nested reference in the property name, and using PropertyUtils.setProperty to handle the setting in this case. Is there no way to accomplish this without all this monkey motion? I would very much like to find a solution that doesn't require me to modify code in struts.jar, and keep those changes up to date in the face of future changes to struts. The fact that the code modified in (c) *has* a check for a subscripted reference indicates to me that *someone* was thinking along these lines in the past. Was the original intent to do this in a different way? What am I breaking by commenting out this code now? Better yet, does anyone have a *better* alternative? I'm not at all averse to writing some tags to hide complexity at that point, or using a derived ActionServlet class (I already am in fact, to load some initialization parameters), but I'd really like to avoid modifying struts itself! Am I being unreasonable? Are there really so few people out there that want such an ability that no one has worked out a better way to do this? -- Erik
