I have an application running on Weblogic 9.2.

The url of my application is something like http://abc.xyz.com/freeR/xxxx.action.

I have a requirement to write the JSESSIONID cookie under the .xyz.com domain.


I created a servlet filter "MyFilter" which creates the JSESSIONID cookie under the ".xyz.com" domain.

This is the mapping in my web.xml
<filter> <filter-name>MyFilter</filter-name> <filter-class>com.abc.filters.MyFilter</filter-class> </filter> <filter-mapping> <filter-name>MyFilter</filter-name> <url-pattern>/freeR/*</url-pattern> </filter-mapping>
I set the cookie value with session.getId().

Now, the issue is when I run the above url , I can see two JSESSIONID cookies getting created .

So, for e.g. if session.getId() returns 4WhSMLrfpGBG1xx5TpmPJ2C7msBL5g2wXngkD1pGgQm6tl7Y17RT!-288131970!1288186719727

one cookie gets created under abc.xyz.com with the value 4WhSMLrfpGBG1xx5TpmPJ2C7msBL5g2wXngkD1pGgQm6tl7Y17RT!-288131970
and the other JSESSIONID cookie gets created under .xyz.com with the value 4WhSMLrfpGBG1xx5TpmPJ2C7msBL5g2wXngkD1pGgQm6tl7Y17RT!-288131970!1288186719727

The difference in the value of the cookies is the last part (!1288186719727 in this case)

Is there a way I can restrict the cookie from being created under abc.xyz.com and secondly why are the values different in both the cookies( only the last part after the ! is different)?


Thanks in advance .

Hi Sudha,

In your insert method, you created a new object of class UserRegistrationForm method using
UserRegistrationForm userForm = new UserRegistrationForm();
Then you are calling a method on the userForm object
ps.setString(1,userForm.getEmail());

But, you haven't populated the userForm object yet, so your userForm.getEmail() will throw a null pointer exception. Hence, you are getting the Exception.
So, you need to populate the userForm object before calling any method on it.
Hope this helps .

Hi Joanne,
Thanks for the reply.
Using StringTokenizer doesn't work as my requirement is to be able to give both the start and end string, say if I can give "Link to " and ";" then I will get all data between them, which is what I need.
But StringTokenizer takes only one delimiter, so if I code something like StringTokenizer tokenizer = new StringTokenizer(text, "Link to"); while (tokenizer.hasMoreTokens()) { System.out.println(tokenizer.nextToken()); }
It's obviously not going to help me .

I would want to be able to select all data between
i) "Link to" and the next ";"
and
ii) "titled" and the next ";".
And so I would need to iterate through the whole content and store the above relevant data in some collection.

Hi,

I need to parse the following content which I am getting after parsing a webpage using HtmlParser. I can store the content in a text document or a String object. I need to extract the words in bold and store it in some Value Objects i.e. basically I need the " Link to" and "titled" data.

Hi,

Is Java 6 compatible with Weblogic 9.2?
The weblogic docs Weblogic 9.2 : Supported Configurations mentions only Java 5.
Just wanted to know if anyone has been successful trying to use Java 6 with WLS 9.2 or is it a no go?

Sorry, if this question has been already asked in this forum, but I couldn't locate it anywhere.

Am I eligible to invest my money in share market if yes,than how can I ?

Well, you can definitely invest in share market ( Not sure if you need to be over 18 yrs to invest in shares, but I assume you are over ) . Easiest way I guess would be to open a demat account like icicidirect, sharekhan etc.
Rest of your questions like which shares to buy to get good profits etc ... I wish I knew

Which version of Struts are you using?

Your folder structure looks ok. Are you able to get the initial page "login.jsp" atleast ?

Now I'm not getting any error/warning messages in the console but still the action class is not getting invoked..and I get 404 error.

Well, your server is unable to find your jsp's.
It seems your jsp pages are not in the right folder.
Can you tell us the folder structure ?

Why don't you try out Struts ?

Basically, what you were doing wrong in your example was that you were creating one thread in B and two threads in A and both your threads of A were trying to manipulate the single thread of B.
Now, the thread "t1" of Class A calls the startSearch() which in turn calls the run() on thread "th" in B. Once the run() is completed the thread "th" is dead(terminated) as per the figure below.



Now, when you call the startSearch() from "t2" of class A, it again uses the same thread object "th" from B and tries to call the start() on it. As this thread is already dead ( run() method terminated in the previous call), it is unable to start and hence throws an IllegalThreadStateException. Bottom line being, you can't start a dead thread.

Changing the run() of Class A as follows should solve your problem :

public void run(){ [B] B w = new B(); [/B] // Move it to inside the run() method w.startSearch(); }

The exception is due to this line
ScriptEngine engine = factory.getEngineByName("JavaScript");

Your factory class is unable to find(and load) the class referred by "JavaScript".

interface I{} interface J{} class C implements I {} class D extends C implements J {}



Class D implements Interface J, and "x is an Object of the Class D"
I x = new D(); // x is of type I but the Object is of Class D
Hence, x is an instance of D and as D implements J,
x is also an instance of J.
Hence, (x instanceof J) is true.

This is a good place to start of Struts Tutorial .
