View Replies View RelatedSo I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

I downloaded Connector/J in the the binary .zip form and extracted it to my C: drive and put the .jar file into my java directories lib folder. I also added the directory of the .jar file into my CLASSPATH and I still get the exception.
I have configured form based JAAS in my app. Basically, in web.xml I have declared security constraints on certain jsp page, declared specific roles, login and error pages. So, my login form is:
<form id="loginForm" action="j_security_check" method="post">
<p>
<label for="name">Username</label> <input name="j_username"
id="username" type="text" required/>
[Code] ....
This works fine when some user tries to access some of the pages declared in <security-constraint> tag of web.xml.
Container automatically manages login process, redirects to login page and if login details are valid, gives access to secured page.
Now, how should I implement login system so that user can go to login page (possibly same login form) and log in from there?

I have MS doc template documents they contain jpg pictures, and unusual formatting Is there a way of actually pulling those templates and do the merge and perform print operation?

I used the PLPDF software to generate a blob in PDF format in PL/SQL. I can open it in a browser but I would rather send it directly to a printer from PL/SQL.
I know I can use tools like BI and Jasper but I want this particular solution to be 100% database solution.
I was wondering of I can use JAVA in Oracle to send the blob to a printer.
I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.
I use the following code but the result is not good. I mean the image quality is not acceptable.
img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
I've also tried :
img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
The result is the same even if I change the image, very poor and unacceptable!

I've been googling information on how to print a pdf in java, and it seems that the java print api is used more for printing from a swing app. What I'm needing to do is send a pdf document to the printer upon user request. I would like my app to work as follows - User selects pdf to be printed- Program determines pages to be printed and deducts amount from user account- If sufficient money, program sends job to printer automatically without popping up the print screen.- If printed successfully, then program tells user it was printed. I'm able to figure out the rest of the pieces, in regards to user input and determining pages of the pdf, except I don't see how I will be able to print the pdf.
I've tried to use this code
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printerJob = defaultPrintService.createPrintJob();
File pdfFile = new File("c://myPdf.pdf");
SimpleDoc simpleDoc = null;
try {
simpleDoc = new SimpleDoc(pdfFile.toURL(), DocFlavor.URL.AUTOSENSE, null);
[Code] ....
But all that I get is junk characters spread across 15 or so pages, for a pdf file that simply says "Hello World". I can open the pdf file on my computer, and print it ok, but when using the above code, it just prints out junk. How I might need to format or setup the pdf so that I can print it correctly. My program could be run on any number of Linux systems, with a multitude of printer types.

I have a secured Struts application in WebSphere that uses FORM j_security_check for authentication.There is also a Post Logon "filter" defined which runs some code after a login is processed.The extract from web.xml showing the login configuration and filter is as follows:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyRealm</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
[code]....
If a user isn't logged into the application and they try to access one of the secured servlets, for example quotes.do, they are directed to the login page to enter their information.If they login successfully, they are then directed to quotes.do, rather than the default "welcome" page. Is there a setting in the web.xml or the post logon filter where I can force j_security_check to ALWAYS go to the default welcome page after a successful login?
