Hi All,

We have a very strange issue. All the time when we have a change that affects only one or two classes in our application we do a manual deploy. Basically, we copy the compiled classes into WebSphere deployment directory and restart the server. We never had any issues before. Last week we did the same thing for one class, lets say A. However, after we restarted the server, we didn't see a change. Checked the time stamp of the file, size, permissions - everything looked good. We removed the file, and restarted the server. The server didn't start complaining that it could not find the class A. Copied file again, restarted. Still - no change... Old information is show on the site. Restarted WAS with Verbose class loading enabled. Checked the path from there the file is loaded - it's correct. Not really sure what is going on. Have anybody had something similar ?

I really appreciate any help or suggestions!

When I retrieved the bean from the session I used the attribute name. I've changed it to form name and everything works perfectly now.

Thanks a lot for your help!

I've done some additional testing. And notice, that validation is not triggered then I have attribute="docForm" in the action tag:

<action path="/ShowFile" type="com.xxx.xxx.action.ShowFileAction" name="showFileForm" scope="session" attribute="docForm" input="/WEB-INF/jsp/error/Error.jsp" validate="true">

When I've removed that attribute, validation is executed properly. But I need it, in order to retrieve bean from a session in the code... Is there any other way to identify form bean?

Yes. After restart it still skips validation. Is that possible that I am missing some additional parameters for a session scope?

I use initial.
<form-property name="fileName" type="java.lang.String" initial=" "/>

Then, in the action class, I print them out, and they came out blank.

Thank you for response. Unfortunately, it did not help. The initial values have been assigned to blanks.And, it looks like the validation is not triggered at all. It goes further to the action class, instead of going to the error page.

Hi All,

I have a web app that uses STRUTS(1.1). For some reason when I changed the scope in the action tag from request to session my validation stopped working.
It looks like it's ignored.

I expect validation to pass with URL: www.site.com/ShowFile.do?lang=EN&doc=4&number=148&fileName=fileName.doc
And fail with URL: www.site.com/ShowFile.do?lang=EN
But it does not fail...

Any ideas?


Here is my struts-config.xml:
... <form-bean name="showFileForm" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="number" type="java.lang.String" /> <form-property name="lang" type="java.lang.String" /> <form-property name="doc" type="java.lang.String" /> <form-property name="fileName" type="java.lang.String" /> <form-property name="type" type="java.lang.String" /> </form-bean> <action path="/ShowFile" type="com.xxx.xxx.action.ShowFileAction" name="showFileForm" scope="session" attribute="docForm" input="/WEB-INF/jsp/error/Error.jsp" validate="true"> <forward name="path1" path="/WEB-INF/jsp/Path1.jsp"></forward> <forward name="path2" path="/WEB-INF/jsp/Path2.jsp"></forward> </action> ...

And validation.xml:

... form name="showFileForm"> <field property="number" depends="required,mask"> <var> <var-name>mask</var-name> <var-value>${number}</var-value> </var> </field> <field property="lang" depends="required,mask"> <var> <var-name>mask</var-name> <var-value>${lang}</var-value> </var> </field> <field property="doc" depends="required,mask"> <var> <var-name>mask</var-name> <var-value>${doc}</var-value> </var> </field> <field property="fileName" depends="required,mask"> <var> <var-name>mask</var-name> <var-value>${fileName}</var-value> </var> </field> <field property="type" depends="mask"> <var> <var-name>mask</var-name> <var-value>${type}</var-value> </var> </field> </form> ...

Hi,

I am migrating java 1.4 application to 5.0 and I have a question. In our application we have a class SomeCollection that extends Vector. And that SomeCollection used everythere in the app to store different types of object.
As I understand correctly, with Java 5.0 vector should be parameterized. Is there any way to make it general? So I don't need to change every line in app? Or the only way to get rid of SomeCollection and use parameterized vector instead?

This is what I have now:
public class SomeCollection extends Vector { ...}

I tried this:
public class SomeCollection extends Vector < ? > {...}
But it gives a compile error.

Thanks.

Hi,

We are migrating from WAS5.1 to WAS 6.1 and I have some questions. The J2EE level of our application is 1.2. I am wondering how critical it is if we leave it at the same level. I also would like to know does WAS 6.1 support J2EE 1.2. If it supports that level, could you please give me some points why it is better to change to J2EE 1.3? Personally, I�d prefer to keep our application more up to date, but I need to persuade my manager to do that. So far, I was not able to find any information on that topic.

Thanks.

Thanks, Bear.
So, you are saying that there is not much difference between writing UI of web application in AJAX or in let�s say in plain JSP. Is that right?

Hi All,

I think it�s a right place to ask general questions about AJAX. Currently we have VB6 client � server application. The application is login-based application and deals with money. As VB6 will be out of support soon, our manager is talking about rewriting the application to web using AJAX. I don�t have any experience with AJAX, but I have some with JS. And it�s not good. So I am wondering will it be appropriate to write client part of secure application that deals with money in AJAX? Is there any security issues? How about browser compatibility? How stable AJAX now and what future does it have?

Well, I have topic below�

https://coderanch.com/t/120706/HTML-JavaScript/window-focus-or-Adobe-plug

Basically, it�s if a pop up window already open, the focus() function gives an error and the content of the window is not reloaded.

Hi ALL,

Is there any other way to set up focus on the window besides using window.focus() function.
I have some problem with it.

Thanks.

I have a web application where user can click a link and PDF file is loaded in a popup window. Users, who have Adobe 6 installed does not have any issues if they did not close popup window and click another link. The new PDF file simply reloads in the same popup window. However, after upgrading Adobe to version 7 or higher, users have to close popup window, before clicking the link to open PDF file. If popup window is open and the link is clicked, the JavaScript error is given:
� Member not found �.

After investigation, I found that if I comment out the window.focus() function in my JS, it works fine, no error is given. But, the popup window is not activated, so user does not see it.
So, I am trying to understand there the actual problem is: in the Adobe plug-in for IE or in the browser, or somewhere else and how can I fix it.

If somebody has any clue, please help. Any help is appreciated.

This is JS I am using:
function openwin(url,winname, winfeatures) { var win = window.open(url, winname, winfeatures); if (win && window.focus) { win.focus(); return win; }

Hi All,

We are running a stress test for a web application. And, after a 4 hours of heavy load the app server (WAS) crushes with OutOfMemory error.
The following piece is from GC log:

<AF[1999]: Allocation Failure. need 32784 bytes, 1090 ms since last AF> <AF[1999]: managing allocation failure, action=2 (0/536803840)> <GC(2002): freeing class sun.reflect.GeneratedMethodAccessor61(30fe9fb8)> <GC(2002): freeing class sun.reflect.GeneratedMethodAccessor62(30fe9e28)> <GC(2002): unloaded and freed 2 classes> <GC(2002): GC cycle started Mon Apr 23 23:54:49 2007 <GC(2002): freed 13628680 bytes, 2% free (13628680/536803840), in 1800 ms> <GC(2002): mark: 1649 ms, sweep: 151 ms, compact: 0 ms> <GC(2002): refs: soft 0 (age >= 32), weak 0, final 50, phantom 0> <AF[1999]: managing allocation failure, action=3 (13628680/536803840)> <AF[1999]: managing allocation failure, action=4 (13628680/536803840)> <AF[1999]: clearing all remaining soft refs> <GC(2003): GC cycle started Mon Apr 23 23:54:52 2007 <GC(2003): freed 298504 bytes, 2% free (13927184/536803840), in 2829 ms> <GC(2003): mark: 2098 ms, sweep: 161 ms, compact: 570 ms> <GC(2003): refs: soft 50 (age >= 32), weak 0, final 2, phantom 0> <GC(2003): moved 12792 objects, 10615880 bytes, IC reason=5> <AF[1999]: completed in 4749 ms>

It looks like there are a lot of soft references to the sun.reflect.GeneratedMethodAccessor class and GC cannot properly clean it. But we don�t use soft references directly.
I am just wondering why this class is used and by whom?

Thanks.
