Re: Best practice for redirecting on session timeout?
Hello, It should be done in the RequestProcessor. If none of your JSP is doing a forward to other JSP directly.

Connection Leakage
Hello All, I have got a application which is running live. (Struts with the usage of DBCP for connection pooling) We have found a problem that at many places we have not closed the connections. To solve this problem we thought of increasing the number of Maximum active connection. We are also thinking if there is a way by which we can configure the connection pool so that it should close the connection after some time if it is not done by the code.

Slow Response Time (Tomcat 5.0.16)
Hello All, I am using Struts Framework and Tomcat 5.0.16 for the development of my application. The application seems to be working very slow as there is a lot of data transmitted over the net. I used the HttpCompression technique to reduce the response time from the server to browser. But this has solved the problem in one direction i.e server to browser.

HTTP Compression
Hi, Using the servlet 2.3 specification one can compress the data (gzip) while sending from server and uncompress on the client (Browser).

Re: Intermediate loading page
Hi Puneet, I am really in needs of such a type of javascript code. This code should work both on IE and netscape. I know i need to use the DIV and LAYER tag.

Regards Shailender Jain [EMAIL PROTECTED] wrote: But if you change your approach of showing work in process label, while the report is being generated, to this one, both your problems get solved. write some javascript that will show a layer which is opaque in the browser, and let that layer show some text like 'processing...' in blinking mode. invoke this function onSubmit event of your screen. The report gets fired at the server side and when it gets generated it send response to the browser the advantages of this approach are 1.You avoid one network round trip ( which is a primary focus for architects of remotely accessible applications, that have high network latency) 2.There is no flag at the server side therefore half complete reports get completed and those are not sent anywhere and does not cause any problem. do u think it can work for u ?

I moved the report generation to a thread and set a session variable which is a boolean indicating that a report is currently being generated. Once the report generation is complete that session variable is set to false again. I have come across another problem though. Say a user starts generating a report. The boolean session variable is set to true. If the user tries to generate another report while the fist oneis not complete, then the boolean variable is checked and the user is not allowed to generate another report (until the first one is complete and the boolean session variable is set to false). In this scenario, if the user abruptly closes the intermediate page which is supposed to load the report , then the session variable is still set to true (indicating report is being generated) as the thread on the server has not finished running. If the user now tries to create another report then s/he will not be allowed to do so (until the thread on the server is done running). So I guess my question is : Is there any way to set a session variable when the user closes a browser window abruptly? Or is there another way to approach this problem? Yes and no. Since the browser sends no closing informaiton to the server, there isn't much you can do... however using HttpSessionListener, you can know when the session is destroyed, in the case of the user wandering away, this would be a session timeout... you can use the event to get some information from the session, but not necessarily the exact cause of the session destruction. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ForwardSourceID:NT2806 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Testing for con.close()
Hi, I have implemented the connection pooling provided by Struts for developing my application. The application after going live gets hang quite frequently.

Reporting Tool
Hi, I want to generate some reports in my application. I am currently using Struts as a framework. The current architecture for generating reports uses Crystal Report 9.0 The problem faced with this are 1. The data in the crystal report can be read only from a data source i.e. tables. Therefore there is a need to create some table for reports. 2. The reports needs to be presented in such a manner that the rows needs to be converted into columns. (Transpose) The transpose logic makes the reports response time very slow. 3. There is a need to make a call to IIS. Can somebody suggest a reporting tool which has got the features like Crystal Report (Export, Print, Group, Page Header, Page Break) but can also use the data of the java classes for generating reports. I have heard of Datavision, JFreeReport tools but not sure whether they can take data from java classes to generate reports and have the same features.. Taking data from java classes is important as it will be easy to put the transpose logic in the java code and will in the end improve the response time of reports. Thanks, Shailender Jain

This method will be executed for each request and will be before action class gets executed [EMAIL PROTECTED] wrote: Dear Strusts users, I have a typical requirement where i need to do some business logic before any action class gets executed.

session problem
I am using session object in my application to validate whether the user is valid or not. I am doing this in the processPreprocess() method of RequestProcessor. But in I.E. 6.0 update version: SP1, the session object becomes null. So once user click at any link in the application he gets logged out. The system admin has also done the following configuration 1. I installed the application on a machine having the IP (10.1.252.41). The system admin made a virtual IP (10.1.252.42) and gave me a DSN dbomis.com which can be used to access the application. This DSN points to virtual IP. 2. Now when i access the application using http://10.1.252.41/ or http://10.1.252.42/; in IE 6.0 SP1 then it works ok. 3. When i use the http://dbomis.com/; then the login page come. User is able to login (processPreprocess() method does not check for session while user is logging in). But when the user clicks on any link the session becomes null so the user is logged out of the application. This problem happens only on I.E. update version SP1. On I.E 5.5 this url works ok. Anyone has got any idea why this must be happening
Re: session problem
Thanks Andrew for the response. Should i just put html:rewrite/ in all my JSP or some attributed also needs to be passed. Where should i put this tag in the JSP.

(Its best to make sure you use the html:rewrite tag (or equivelent) for your links though so that your app will support users when they have cookies disabled). -Original Message- From: nikhil walvekar [mailto:[EMAIL PROTECTED] Sent: Friday, 11 June 2004 17:34 To: Struts Users Mailing List Subject: Re: session problem Hi, same thing i have experienced with IE 6.0, it will work with mozilla Problem is that with each request session id is not passed.

Re: Connection PoolingOT?
Thanks for your attention. Abandand connection management can you give more details on how to do this. Masashi Nakane wrote: And if you have a chance to try DBCP , Abandand connection management function will tell you exactly where the unclosed connections are . You will love this. Masashi At 23:33 04/06/08 -0700, you wrote: And Some other guy says the set the max number of connectons to 1. Yes this is another good way, thank you for bringing that up. I had a fairly big app that was throwing away connections and when I set the max connections to 1 it became almost immediately aparent where the problem was. Good suggestion Masashi. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: html:options ....
Hi All, If the someBean.getDefault() has some values which is not there in the collection SORT then the problem is that the select tag will display some value from the collection not the value from someBean.getDefault(). I faced this situation when i had to display a blank combo box and the collection having the data of the employee names. Any idea on how to handle this?

Connection Pooling
I have fished developing the application using Struts and Tomcat 5.0.16 as server. We used the Connection Pooling provided by Struts (DBCP) After the development we have realized that somewhere in the application the connection is not getting closed. Due to this the application is getting hang very frequently. We have actually assumed that the application gets hang due to this reason only. Is there any way to DEBUG where in the application where the connection is not getting closed.
