All,

We are facing an inconsistent issue in our application. We have developed few pages using Prototype AJAX calls and our
application is over https. Some cases, we get "unable to read request from client". We kind of feel that, the issue is with IE6,
AJAX, HTTPS combination and it looks socket connection is opened, but request is not sent to server. Hence, server returns
an error saying "unable to read request from client" and the error is from Tivoli Access Manager / ALTEON.

And if i use HTTPWatch for seeing the request and its strange that the request has header content-length as 16, but there
is NO DATA sent to the server. On some occasions, data is sent. And its highly inconsistent.

I found these articles, but not sure how to reproduce this problem consistently. Can anyone suggest some ideas/fixes.

Hi,

We are trying to use AXIS2 for webservices. Which databinding is efficient and performant?
Is it ADB or XML Beans or JiBX. Can AXIS2 support any other data binding in addition to these 3?
Kindly reply.

We are developing a intranet site based on J2EE techs. The requirement is, as soon as the user logs into intranet application, we should be able to show his/her windows network user id.

For. e.g Assuming, mylibrary is developed in J2EE, as soon as we click http://mylibrary, it should display the logged in windows user id.

Kindly assist.

All,

I have a requirement where two business classes should share the same value object. And these two business classes should be instantiated one per request and value object is common for both these.

<bean id="bus1" class="com.foo.Business1" scope="prototype">
<property name="account" ref="acct"/>
</bean>
<bean id="bus2" class="com.foo.Business2" scope="prototype">
<property name="account" ref="acct"/>
</bean>
<bean name="acct" class="com.foo.Account" scope="singleton">
</bean>

I need this acct to be singleton for bus1 and bus2 instances and not for entire IOC container. In this way, when a user logs on, bus1 and bus2 will share the same acct. And for another user, a different acct instance has to be created, but shared between bus1 and bus2.

Is this possible in Spring or should i do it programmatically?

Kindly help.

Hi All,

I have been hearing about MAC(message authentication code). What is this all about and should this be used in J2EE applications? More specifically does this has to do with Mobile applications, meaning any web applications accessible through mobile device browsers?

In case if we use clear trust / Tivoli access manager / any other 3rd party tool for authentication, then should we still use MAC in our application?

Could anyone provide pointers?

Hi,

The reason for not using CSS is, our application should be accessible from mobile device. And not all mobile devices support javascript or CSS. This is where we got struck.. and i am searching for solution
Hi,

If i put a submit button, then i need to do some styling to make it look like <a> tag. Without CSS, can we achieve this styling? Also, if i put submit button, then the user will not know which all links he previously visited. Am i right?

Is there a way to solve?
Hi Ulf,

The constraint is, we should not be using CSS. So how to address this?

Hi All,

In our application, we have a requirement to put HREF's and on clicking it, it should take to next action with few parameters. We do not want to append parameters in HREF using '?'. Also we should not be using javascript/CSS to submit the form.

Is there a way to submit a HREF without javascript.

Thanks,
venkat
