Failed to access database through applet! Please help!
Hi there,
I'm writing an applet to connect to a Microsoft Access 97 database situated on the same computer where the applet is invoked.
In appletviewer, it works fine...
appletviewer hello.html -J-Djava.security.policy=policy.plybut how could i get it run on Internet Explorer 5.0?
It always complains about failure to find the class...
Abstract of the program is shown below:
public class TestDB extends JApplet{
private Connection connection;
private JTable table;
public TestDB() {
String url = "jdbc:odbc:test";
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
connection = DriverManager.getConnection(url);
catch (ClassNotFoundException cnfe) {
System.err.println("Failed to load JDBC/ODBC driver");
cnfe.printStackTrace();
System.exit(1);
catch (SQLException sqle) {
System.err.println("Connection Err");
sqle.printStackTrace();
getTable();
setSize(450,150);
private void getTable() {
Statement st;
ResultSet resultSet;
try {
String que = "SELECT * FROM ChartOfAcct";
st = connection.createStatement();
resultSet = st.executeQuery(que);
displayResultSet(resultSet);
st.close();
catch (SQLException sqle) {
sqle.printStackTrace();
Thank you so much!
Jess
Thank you.
If i were to use a policy file... what should i do to let the browser know about that? Sorry i'm a completey idiot on this.
expected outcome:
typing an URL on the browser, say, http://abc.com/test.html --
an applet will load and the database in the root folder (applet is also in here) would be retrieved.
Thank you.
Jess

Hi, I want to display the number of Passed / failed tests in Testtand xml report , please help me.
My requirement is later i should be able to display these number of passed/failed test in report header too.
Solved!
Go to Solution.I have attached a sequence to give you an idea of how to get the Result count (I didn't check it's working ), I have used "SequenceFilePostResultListEntry" callback to calculate the Result Count,
and the Result Count is passed to the "ModifyReportHeader" through File Globals, where you can edit the XML file to show it in the Repot (follow the link in my previous post).
Hope this helps

I can't access my icloud account , please help
I can't access my icloud Account, please help .
How are you trying to access it? You can't access the iCloud website on Safari on an iPad, you have to sign in in Settings>iCloud and access the data through the relevant apps.
Have you successfully set up an iCloud account? Can you log in at http://icloud.com on a computer? What operating system are you running on your iPad?
Do you get an error message when you try to access it?
You really need to post more data with a question like this, just 'I can't access' doesn't really allow for any sort of answer. -

Open a new Finder window, Finder > File > New Finder Window, and it should appear on the left under Devices.
If you don't see it there, or to get it to show up on the Desktop: Finder > Preferences... General tab, check External disks to have it show on the Desktop, Or Sidebar tab, check External disks under DEVICES. -

Caonnecting ms access database through tomcat5.5 query
Hi,
I have installed tomcat5.5 and jdk1.6 on my machine which has Windows server2003 as OS.
I'm not able to clearly underdstand the steps in tomcat docs for connecting to database and the changes to be made in different files.
Can someone tell me detailed and clear steps for connecting to an ms access database through jsp?
Thanks in advance for your suggestions.I'm not exactly sure why you have this problem. I know that the Microsoft SQL Server driver has a parameter "readOnly=false". Check your DB2 docs to see if you need to set a flag like that, too.
Maybe it has to do with transactions and auto commit. See if DB2 assumes autoCommit true or false. Maybe you have to explicitly commit your INSERT.
Maybe you're writing to one database and opening another. Make sure that's correct.
There are other suggestions that I'll offer.
You do all that work with a database in a constructor? Bad idea.
You've got database and UI stuff all mingled together. Ever heard of MVC separation?
Be object-oriented - start by designing an object to encapsulate all those items you're trying to INSERT.
Then write a Data Access Object (DAO) that does CRUD operations for that object. Test these thoroughly, preferrably with JUnit, until they're 100% perfect.
Then have a separate UI that instantiates these objects and calls their methods. The persistence layer shouldn't know about UI stuff, and the UI shouldn't need to have any persistence code in it.

Hi,
When did you make the purchase? Can you try signing out of the CC desktop app, and then signing back in?
I'll see if I can get direct support sent your way as well. How much longer are you available for this evening? We can communicate directly as well if you prefer.
regards,
steve

}To give an applet special privileges you can specify the prifs in the java.policy file or sign the applet and choose "yes I trust" or "yes I allways trust" when the applet is loaded.
To give special prifs with the java.policy, it should look like this:
grant {
permission java.lang.RuntimePermission "usePolicy"; // prevents the popup from showing for signed applets
grant codeBase "file:C:/-" {
permission java.security.AllPermission;
grant codeBase "http://localhost/-" {
permission java.security.AllPermission;

my children enters wrong password several times on problem my ipad ..., the was it is indicated that it was disabled ... how can i access my ipad thanks please help ... thank you
If it's reached the point where you can't try re-entering the code then you will need to connect the iPad to the computer that you normally sync to and you should then be able to reset the iPad and re-sync your content to it - from http://support.apple.com/kb/HT1212
If you repeatedly enter the wrong passcode, your iPhone, iPad, or iPod touch will be disabled for longer intervals before you can try again. After too many unsuccessful attempts, you won't be able to try again until you connect it to the computer with which you last synced it.
You may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 -
