I've already added few jar files... But right now, I'm getting this error...

java.lang.NoClassDefFoundError: org/jfree/data/general/Dataset


After searching that jar file... I downloaded and put jfreechart-0.9.19.jar this file in my WebContent/WEB-INF/lib folder....

Any idea about this...

Hi,


I want to implement iReport from Struts action...

I have got some code... But there is some problem...

Anyone has some idea about this....

Something like this....

ServletOutputStream outputStream = response.getOutputStream(); System.setProperty("jasper.reports.compile.class.path", "/WEB-INF/lib/jasperreports-3.7.6.jar" + System.getProperty("path.separator") + "/StrutsExample1" + "/build/classes"); File reportFile = new File( realPath + reportName + ".jasper"); Map parameters = new HashMap(); String loginName = "gerry"; parameters.put("loginName", loginName); bytes = JasperRunManager.runReportToPdf(reportFile.getPath(),parameters ,dbConn); if (bytes != null && bytes.length > 0) { response.setContentType("application/pdf"); response.setContentLength(bytes.length); outputStream.write(bytes, 0, bytes.length); outputStream.flush(); outputStream.close(); }

Any idea about this....

Yes. I think , 3rd option is partially correct in my situation.

Actually, its a framework based application, And it might not be getting appropriate
parameters to login in to, besides Login name and password. So its getting redirected to login page and responding it to me with login page source.

I had some other way around idea. I'm almost sure its not possible but just asking...


Is it possible if we can invoke a click event in Java??, and the button of which the click
event is to be fired, is in a JSP..... Is it possible in any other way (through java)....???

you could add the file to the context watch list, but when that sees a change it would redeploy (and reload) the file but bouncing the context may not be the most elegant solution.

@David O'Meara : Should it be added into web.xml or struts-config.xml?

The given code is understandable, but its not making the login happen...

It is responding with source code having Login page contents instead of Home Page.

Hi,

I want to Login into a website through a java code.

I found out some thread like this

http://www.1your.com/drupal/LoginToWebsiteByHTTPPOSTCodeListing

It uses HttpURLConnection in java.net package.....

It can fetch response from the URL when we give User Name & Password to it.

But i'm not able to get proper response i.e.

Instead of getting Home Page source , I'm getting the source of Login Page from that response.

I need to get proper response..

Please refer to that link....

Here is some part of the code....


HttpURLConnection urlConnection = doHttpPost(TARGET_URL, urlEncodedContent); String response = readResponse(urlConnection); System.out.println("Successfully made the HTPP POST."); System.out.println("Recevied response is: '/n" + response + "'");

When you write like this

String some= Some_String + Some_Other_String;

The (+) symbol will CONCATENATE any value or null in the given strings.

As your both strings have NULL assigned to it. It'll just return null and append
it with previous string.

Are you having the following pattern of contents in your file...???


Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value , Some key = Some value ,

If yes, then go ahead using this pattern...?? And explain your requirement....


If no , then put some sample data file of which you want to upload data....

Now its looking neat....

No, I haven't implemented serializable to my POJO.... But is it mandatory that the class MUST be implemented with Serializable interface...??

I also have some other POJO's which have been set in Session attribute as List of POJO objects.... But only one of my class gives this exception....

Hi,

I've a POJO of which i create an ArrayList<myPOJO>

I'm storing it in a session attribute my ArrayList<myPOJO>

Considering above scenario....

Rarely, i get NotSerializableException refering to myclass i.e. myPOJO

Is it related to following.....?

session.setAttribute("myPOJOlist",list); //list is this ArrayList<myPOJO>

Thanks,
Aditya Kanitar.

Thank god... Problem has been resolved now...

Thank you Guys....

It was related to, the way objects were declared.....

How did you pass parameters to myObj? particularly the getMyMap() method? Your sample code doesn't show how that method provides you different Map objects for different users.
Is this a real code or just an abstract code?

And i had some static var i.e. some collections like arraylist and maps...

Now i've removed it....

Still its not working....

And yes, its a real code... The data we bring over here is dependent on login name

I get that login name in myClass...

But, I think that is not related to this problem....
It gets appropriate user....

Duc Vo wrote:Lol, that's funny. You didn't have any problem with your original code in term of accessing the session scope. Two things:
1. How did you create the myObj object? Is it a new instance everytime a user logs in? Or is it created when the application starts?
2. How did you test the two sessions scenario? From 2 browser windows on the same machine or from two different machines?

There was one issue...

Now i've declared myObj like this


<%! myClass myObj=new myClass(); %>

But, still problem persists and scenario is like this

Two user logs in separate machines

And still same problem is happening.

Currently, i have not modified the attribute names....
