Long running reports using java servlets

Hello,
I'm running into a problem using java servlets to produce database reports and sending them back to the client browser as excel or html. The problem comes into play when the user has submitted two reports then goes to run a third and the browser hangs. I realized now that this is because of the two active connections that the user already has to the app server. Does anyone have any suggestions on how to get around this? I'm trying to now write the report to the server, and provide the browser with a url, but it seams as though the connection isn't totally closed even though I close the response printwriter.... Any suggestions would be greatly appreciated....

Unfortunately I dont have an answer to your question, but:
If the reports are large/long running, should they be generated on demand? You could schedule the reports to be generated every day, month or whenever appropriate, stored on the server and then quickly pulled by the user whenever needed.

XML Reading Using Java Servlet

I need some help in reading xml file using java servlet.
May i have some sample codes to read xml files?
I would really appreciate your help. Thanks!!!

This grabs a url and parses it with a servlet.
URL befreeUrl = new URL(urlString);
uri = new URI(urlString);
URLConnection yc = befreeUrl.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
factory.setValidating(true);
out = new OutputStreamWriter(System.out, "UTF8");
DefaultHandler handler = new BeFreeRequestSAXParser(); /* custom handler class */;
parser.parse(uri.toString(), handler);
in.close();

How & where to use Java script to create new button in object detail page

Hi All,
I want to create "New/Add button" in object detail page. If i am not wrong i need to use java script for that but could you please let me know how & where to use Java script to create new button in object detail page in CRMOD.
Thanks in advance.
Regards,
Manish

Any related object on the detail page should have an "Add" or "New" or both buttons by default - This is vanilla functionality and will do the required action.
If you want to modify this behaviour and do something tricky you will potentially have to go for javascript. You should add the javascript on a custom web tab on that Object.
Admin --> Application Customization --> Contact -->Contact Web Applet
Now, add your javascript in the code area, after you select the type = HTML for this web applet, expose this web applet on the Contact detail layout and your javascript will be invoked whenever this page is loaded.
Check this online document to see how javascript can be embedded in CRM on Demand http://helponmyproject.com/TTOCOD/

Using Java Servlet with CSV

Hello!!
I would be obliged if some one could tell me anyway of using CSV (Collaborative Source Versioning) with Java Servlets. I have searched and the only package that I have found is jCSVSlet but I can't figure out how to use it. I would be obliged if anybody could point out any other packages that can be used for File Versioning or if anybody could send me any examples of JCSVSlet or any other related software.
Saad Tawwab

And what do you mean by "with"? Do you want to control versions of the source code of the servlets, or do you want to write a servlet to control version of the source code of something else?

Problem of Query Chinese words in MySQL using Java (Servlet java)

It outputs nothing!
if i change the 'Chinese word here' to English,it have result!
But if I query in mysql, i can
If the 'Chinese word here' is get in a form, (ie 'Chinese word here' is got by req.getParameter but not built in), it can display result, why???

Hi hlj_zhj
Oh your method works, I change the Gb2322 to Big5,
and I have a question about your "return shift", shift is not defined in your part of programme, so I change to follows:
private String getISO(String gbstr){
String temp=null;
try{
String temp_p = gbstr;
byte[] temp_t = temp_p.getBytes("Big5");
temp = new String(temp_t, "ISO8859-1");
catch(Exception e){}
return temp;
ANOTHER question, Some of my BIG5 words contains "Hong Kong Words,eg:�`��", therefore, using temp_p.getBytes("Big5") not work in this case, do you have any suggestion in this case? thanks

Please try this code:
import god.java.pdf.*;
PDFWriter pw=new PDFWriter(new OutputFile(new String("sample.pdf")));
pw.print("This is your text.");

i closed the first resultset and statement object. now open the second resultset and statement..
here the objects are created but the while doling "while(rs.next())" is not executed...was an error thrown?
if not, just sounds to me like no database records were found/returned
i.e. empty ResultSet

Java servlets - JDBC

hi,
I have a problem... i would like to fetch some strings from the database using JDBC and create a tree structure using java servlets to be displayed on a browser using html.
Currently i have tried using a hashtable as well as defaultmutabletreenode, both of which grew complicated and did not give the desired results.
Pls help...

I tried using both a DefaultMutableTreeNode
containing all the other nodes as child nodes and a
hashtable with a series of internal hashtables -- and
passed it to the servlet displaying the html
l content.
Is there a better/simpler data structure to use in
this case other than a Hashtable and a
DefaultMutableTreeNode?How should we know? You're asking what is better to solve your problem, without saying what your problem is. (Hint: "I can't do this" or "It doesn't work" are not useful problem descriptions.)
If I were doing this, and if I had to build a tree structure in memory before producing HTML from it, I would use DefaultMutableTreeNode. But then I don't know anything about your problem.

Problems calling Java Servlets from HTML pages Online

Hello
I have created a Web site using Java Servlets, and have acquired some servlet enabled web-space however i am having some difficulty in calling the actual servlets from the HTML pages i was using the line of code as follows
http://localhost:8080/servlet/....
followed by the name eg.
http://localhost:8080/servlet/Login
however this doesn't seem to be working i have also tried using the exact address of the servlet but this didn't work either
i.e ..servlet/Login.java
I was wondering would anyone have any idea as in how the servlets should be called
Thanks very much

Once you write the Servlet code, you have to compile and put the classes in the server classpath. To refer these servlets from your pages, you have to configure them in the server configuration(typical a xml file). There you define how you are going to refer to the servlet(/servlet/Logon) and the correponding class.

Java Servlet/Html link problem

Hi,
I have been using the Java servlet to create the html code itself using the PrintWriter.I would like to know if it possible to input ALL the code into -
PrintWriter out=null;
out.println("<Html><Body>the entrie html code</Body></Html>");
or must I input in this form?-
out.println("<html>");
out.println("<Body>");
out.println("<The entire html code>");
out.println("</Body>");
out.println("</Html>");
Does it really make a difference?
I would also like to know it is possible to retrive data from a database and (via servlet) input the list of data into the combo-box of an html Webpage.
Thank you very much for your assistance.Kindly acknowledge receipt.
Yours sincerely,
Aeshan
PS- I'll send more information soon

Your answers are yes ...and yes.
But don't use:
PrintWriter out=null;
Use:
PrintWriter out = response.getWriter();
Usually the println() method is used to make both the servlet source code ...as well as the html it generates ...a little nicer to read. This may or may not be important to you, but may matter to your employer and those who maintain your code in the future.

Labview Java Servlet interface

Hi. I am researching and making a plan for a project. The Goal is to Use LabView trough the internet with a java servlet to make circuits and designs in the front panel and back end (block diagrams).
I have to use Java (Servlet) , PHP, SQL, CGI in a project.
Is this feasible or am I aiming in the wrong direction.

I wasn't suggesting that you work for NI. What I was saying that if you want to 'create' anything programatically, you will be on your own as the API for creating front panel objects and wiring on the block diagram is not documented or supported for general users. This is a topic called LabVIEW scripting. If the idea is to simply let remote users 'run' an existing LabVIEW program, then that's pretty easy to do. But, if you want to give remote users the ability to create a new LabVIEW program without having LabVIEW itself installed, then you have a very difficult task ahead of you and you might want to look into possible licensing issues. Logging into a remote computer with something like VNC is doable but I don't think that is was you are attempting. If you do want to pursue LabVIEW scripting, there is a forum on that suject at http://forums.lavag.org/.

Taking control back while calling stored procedure using java programme

I have stored procedure to load data. This procedure is invoked by java program.
The stored procedure take around 10 to 15 minutes to do complete loading of database. I want to write stored procedure when it starts loading of database at the same return the control to calling java programme so that java program can do other operation i.e. java program can not wait for control back from stored procedure.
In short stored procedure runs in background and return control back to java program when stored procedure is invoked. Is it possible then How we can achieve this.

U can acheive this using Java Threads. Create a thread submit this loading job. Once you submit the thread, you will get the control back to do other stuff.
