How to distribute html component between different web applications?
Hello. I have a project which consists of several modules. Each module is a separate web-application which can be deployed on a separate application server. All modules must have one menu. The problem is how to implement the menu.
It would be good to maintain it as a separate project and to distribute it between modules as a jar archive. I have an idea to create a custom tag library which will generate and insert html code where it is necessary. But modules can look different, they can use jsf, richfaces or jsp for the page rendering and the menu must suit the page. So I think that the data and the rendering mechanism should be separated somehow.
Thanks.
Starting with Servlet Spec 2.3 (I think) the push has been towards complete web applications; even if it means duplicate files in each (disc space is exponentially cheaper than it was a decade ago).
The easiest way to manage duplicate files is to keep a single copy for development and use build tools like ANT, Maven, etc.. to assemble your web applications at build time.

How to share HttpSession between different web application ?
I have two web application ( ie two different war files), I discovered that the jsp in the two war files are not able to share the HttpSession, may I know how to you share the HttpSession between two different web application ?
From the api doc:
"Session information is scoped only to the current web application (ServletContext), so information stored in one context will not be directly visible in another."
You can not share a Session object between web apps. You can create your own sessions using a database, textfile or hashmap. Do a search on the O'Rielly web site for psuedo-sessions. -

Sharing object across 2 different web application
Hello,
I do not know if this is a right place to ask this kind of question...
I have two different web applications running on 2 different tomcat servers.
One of them creates one object ( say myComplexClassObject) which is serializable..
and I want to share this object in another web applications.
Both the apps are developed using JSP and servlets.
Is there any way, I can make this object available in another application ?
As the request object can not be used across 2 different contexts, I can not set it as attribute on request.
I tried serializing myComplexClassObject in some test.dat. Problem going by this way is that
how do I send this file to another application ?
What I did is as follows....
In the first app , I created the object and serialized it in one file test.dat. In the same app I read
test.dat and send the content as query parameter to a JSP in another app. That JSP collects all the query parameters
and constructs a big string out of it and then writes it to a file, test2.dat and tries to deserialize this.
File sizes come out to be same. But it gives me StreamCorruptedException.
Any idea, where I am doing wrong ? or any other way to share this object or to send the file to another app?
I can not use FTP for some reasons. Size of the test.dat file is more than 10 KB.Some possible solutions:
Use a webservice calls to pass the object,
Use JAXB to convert the object to XML, pass the XMLover HTTP or a socket and use JAXB to convert the XML back into an object.
Store the object as a blob in a database.
Store the object in a Java aware database that can handle Java objects.
Store the data in the object in a database.
I am curious as to what information ot functionality is contained in this object that you feel the need to pass it between two servers. -

How to enhance the context menu in Web Applications - BW 7.0
We have to enhance the context menu of several Web Applications and,
initially, we based our solution on the paper "How to enhance the

described on the paper refers to the BW version 3.0 and we need the
solution for the BW version 7.0. The technical content described on the
paper, version 3.0, is very different from the content of the version
7.0, used by us. Is this feature available for the version 7.0?Hi,
did you find a solution already?

How sharepoint understand when user requests for web applications by their DNS names
HI
I configured Alternate access mapping in my sharepoint farm for default ,intranet zones
and spt farm has two web front end servers and they load balancing by F5 device
in WFE servers there are different web applications are running on different ports
so here I want to know how load balancing works, load balancing configured in F5 device.
when users request a webapplication from browser (ex http://cms) where this request will go
1)when I ping cms and other web applicaations it returns me a loadbalancer server IP for all web applications;
ping cms : it returns 10.xxx.0.80 , same ip returns when I ping for other web app
but ex CMS web application run on the 10.xxx.1.26:81 port in sharepoint server
2) and these sharepoint web applications running on different ports in sharepoint web servers , so here how sharepoint understand when user requests for web applications by their DNS names
http://cms and http://products etc
adilI'm not sure if the F5 can add a port number (I'm not an expert on load balancers). But in general if you design the SharePoint site to run on port 81 then you need to have port 81 appended to the request or it won't work. http://cms in your
example would take you to http://cms:80 not http://cms:81. But in general DNS will resolve the address back to the F5 load balancer. The load balancer will look at the header of the HTTP request (which contains the original address you requested)
and forward the request to the appropriate web front end IP address. If your web front end is using one IP address for multiple sites then those sites need to be differntiated by using a custom port like 81 (which must be included in the original request)
or because a host header was bound to the web application when it was created. If they are running on different port numbers then the request must include the port number by the time it gets to the SharePoint server.

How to avoid directory listing in java web applications.
how to avoid directory listing in java web applications.
That is on typing the url of the application it should not the directory listing. Welcome tag in web.xml doesnot fully solve the problem, since still the images folder etc is still accessibleI know of two ways.
If you're using tomcat and have access to the conf directory.
Edit your $TOMCAT/conf/web.xml. Find your default servlet properties and change
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>to <servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>And restart your server. This will affect every directory on the server, and return a 405 directory browsing forbidden error.
Another way, is to place an index.jsp inside each directory with a simple one line redirect to your applications CONTEXT_PATH.response.sendRedirect("http://yourserver/yourapp/");This will only affect specific directories which contain these index.jsp files.

HT3819 How do I share music between different users on the same computer?
I understand Home Sharing helps me share music across different computers. How do I share between different users on the same computer? We have a few instances of iTunes on a single computer and have to download from the same CD each time. I must be doing something wrong - seems crazy to have several copies of the same song on one hard-drive when Home Share allows for sharing across computers - how do I share within the same computer? Please outline specific steps. THANKS.
Hello Whigged-out,
It sounds like you would like to share one library between two different users on your iMac. I found an article with steps you can take to accomplish this:

How to exchange data between two web application (servlet)
Hello, all,
I have two servlets: SerlvetA and ServletB, they are deployed as web appA and appB in the same web container(tomcat)
How ServletA exchange data with ServletB?
I have tried follow methods:
1) appA and appB could not share HttpSession, so I could not transfer data through session
2) I write a new sigleton java class called AppBroker, servletA get AppBroker's instance, and set some data into the it. ServletB could not get the same instance of the AppBroker, because the appA and appB use different class loader.
tell me how to?thanks reply, but
1. static class can not solve the problem, it is same
as my sigleton class method, as different web app use
different class loaderhmm... at least in tomcat this seems not be true since i can use static classes in one webapp that are available in another web app on the same host/servlet runner.
Maybe if you build your own classloader than the "scope" of the static class is limited to that classloader (for my understanding this shouldn't be the case since i think it depends on the instance of the jvm and not of the classloader..?!).
2. rmi and object serialization are too expensive!
I am working on how to use jndi to solve this problem.
And I think this maybe a Sevlet specification's
shortcoming: maybe a Local Method as EJB local
interface need been introduced into servlet spec.
could you suggestion other methods?none at the moment. i guess the basic methods are listed.
Maybe there's just one left, a really ugly one. Depending on what kind of data and how often you have to exchange you could think of building a file-based queue, i.e. a dir where you drop files in an read out from the other web app (maybe based on a file/directory listener). But this would only be an appropriate way to go for kind of email and messaging systems i guess... -

How change information between two Web Applications?
Hi,
Has anyone any code sample or article how to build
a "bridge" that would change data stored into session and servletcontext
between two separete web application in same servlet engine?
What I have understood is that they can not normally share same
session or servletcontext data...
Thanks,Hmm...
Text in this Sun's tutorial says:
"This lesson, however, shows you what to do if your servlet requires a resource available from its own server"
The actual problem is following:
- In Web Application 1 servlets/jsps stores data into session object and servletcontext
- then user can request a page in Web Application 1 which should "activate/launch" Web Appilication 2 and
pass some session objects or objects stored into servletcontext from Web Application 1 to Web Application 2.
How to do this, it's the problem.
