Access a database in applet

2002-4-17 15:46
I can run application program to handle a database ,
But when I convert the code of application to the code of applet,
then i run appletviewer ***.html;
it tell me that it cant access the database ,
"java.security.AccessControlException: access denied (java.lang.RuntimePermission
accessClassInPackage.sun.jdbc.odbc)"
why?
How to resolve it!
thanks

This is due to the Default SecurityManager in Applet.If u run as a simple application u don't get any AcessControlException.
By Default Applet is having its own SecurityManager and for Applications haven't.
So two possiblities are there to acess the DataBase.One is by writing a permission file for the SecurityManager and add to the Envroinment.ie assigning permissions
Other is write an servlet which retrives data from the database and the applet gets data from the
servlet.This the the normal way which people are using.

How to access remote database using applet

hi all,
I want to know how to access remote database using applet,
Please help me anybody.
Regards

If the database is on a public server, you probably can't access it directly (security wise). You can make your applet talk to a server-side application, which makes the database calls on behalf of the applet. But even in an intranet environment this setup is often preferable, because you don't need to distribute a JDBC driver to all your clients.

Access a file using applets

hello friends,
i'm trying to access a file using applets but i'm getting security error.
similar error for accessing the data base also so pls if you know help me how to access file/database using applets.

You need to use a signed applet and know where the file is and in an accessable area; signing an applet will not allow you to go on a "fishing expedition" through the file system.

WHY can't I access my database from an applet???????????

The security code won't let my applet access its own database (from its own server)..
I'm using getDocumentBase()
to try and tell it that it is my own damn file..
I keep getting :
java.securityAccessControlException: access denied <java.util.PropertyPermission jdbc.drivers write>
...etc.
This applet crap is really starting to piss me off. I can see why they came out with JSP.
All I need to do is access my database, update it, etc. It kind of defeats the purpose of being able to do jdbc from applets if you can't even access the database on your own damn server.
If you all don't have a clue, I'm freakin switching to PHP--I'm tired of this crap-I was thinking Java was a damn good language until I hit applets.

The simple answer to your question is: Because of security concerns.
The somewhat longer answer is that directly accessing a database from an applet is generally not a good idea. A lot of security-critical code like DB username/password must be hidden in the applet which potentially can be downloaded (and disassembled) by anyone that hits your webpage. Maybe you do an intranet solution with trusted users but that is not what applets were originally designed for.
The clean way is to make your applet talk to a servlet that talks to your database.
If that is not the way you want to do it, make sure that all client policy files (yes, on the browser machine) contain the permissions that your applet needs.

How to access database from applet using connection pooling.

Hi,
I am using tomcat 4.1, JRE 1.4.2_10, MySQL 5.0, and IE 6.0. I can access the database using connection pooling from JSP without problems. But, if I try to acess from the applet, I get the following exception (related to JNDI.):
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
I know what this acception means, but I don't know how to fix it. I set up connection pooling in my Tomcat 4.1 that talks to MySQL 5.0. As I said, when I access from jsp, JNDI works. But, applet complains. Please help. In my applet, the following code accesses the database:
ArrayList toolTipData =
      access.getToolTipData (projectName,interfac);This is the snipet of my Access class:
public ArrayList getToolTipData (String projectName, String interfac) {
    System.out.println("In getToolTipData");
    ArrayList toolTipData = new ArrayList();
   try{
    Context ctx = new InitialContext();
    if(ctx == null )
        throw new Exception("No Context");
    DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/interfacesDB");
    if (ds != null) {
      Connection conn = ds.getConnection();
      if(conn != null) {
          Statement s = conn.createStatement();
          //For some reason paramtized queries don't work, so I am forced
          //to this in slighly less eficient way.
          ResultSet rst = s.executeQuery("select * from interfaces");
          while (rst.next()) {
             if (rst.getString("Project_Name").equals(projectName) &&
                 rst.getString("Interface").equals(interfac)) {
               System.out.println("getToolTipData: ITG #" + rst.getString("ITG"));
               toolTipData.add("ITG #: " + rst.getString("ITG"));
               toolTipData.add("SPNE Prime Name: " +
                               rst.getString("SPNE_Prime_Name"));
               toolTipData.add("PD Prime Name: " +
                               rst.getString("PD_Prime_Name"));
               toolTipData.add("IT Prime Name: " +
                               rst.getString("IT_Prime_Name"));
               toolTipData.add("MLC Priority: " +
                               rst.getString("MLC_Priority"));
               toolTipData.add("Gary's Prime: " + rst.getString("Garys_Prime"));
               toolTipData.add("QA Prime: " + rst.getString("QA_Prime"));
               toolTipData.add("Brief Description: " +
                               rst.getString("Brief_Description"));
               toolTipData.add("Project_Status: " +
                               rst.getString("Project_Status"));
          conn.close();
}catch(Exception e) {
    e.printStackTrace();
return toolTipData;
....

The jsp runs on the server, whereas the applet runs on the client so
you must package with your applet any jndi implementation specific classes
and
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory" );
props.setProperty("java.naming.provider.url", "url:1099");
Context ctx = new InitialContext(props);
Object ref = ctx.lookup("...");

Thank you so much!

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.

i want access to database in page html with use AppletFirst of all, that doesn't make any sence, if it's a single user application make it a java
application.
If it's a multu user application make it a client server where the web server connects to
the database when the client requests a connection.
When the applet connects to the database any client running the applet needs a
connection to your database server, the client needs the jdbc drivers and the client's
jre needs to find them (set classpath with runtime parameters or set the classes in
javadir lib). After that the client needs to change thiere java.policy or you need to sign
the applet.
Needless to say that's a lot of trouble. And if you go through all that trouble the client
can de-compile your applet and see the connection to the database server and the
server name. Now the client can destroy your database or worse see date it is not
supposed to see.
Since you are a brainless ... who needed to post this question 6 times did not respond to any of my post in your other threads I can just say good luck with your problem.

It doesn't make sense to read a database directly from an applet. If an applet needs data from a database is should request if from the server which the applet is located on and the server should do the actual database actions.
The whole point of applets is that they require no installation on the client machine. If you have to change policy files or the like, you might as well install a Swing application. Furthermore accessing a database tends to depend on how the client is set up on the network. Any sensible network has firewall settings that block access to the database ports to any external access (and, again, if you are limiting the facility to a few internal machines then why not just install a program on them).

Database in Applet

I use oracle as database, and i'm trying to show data from a table into applet form, but i've problem with accessing jdbc driver. I'm sure that my classpath and path setting are correct, and the errors are about AccessControlException and classLoader. I make this access but not in applet type and it works. Can you all help me and give me an example, cause this is my homeworks.

This is due to the Default SecurityManager in Applet.If u run as a simple application u don't get any AcessControlException.

<snip>The subject of this forum is Oracle databases. How does your problem relate to that subject?
Two bits of advice:
1) Make sure you ask questions in a forum related to your problem.
2) If you want to be taken seriously as a professional, drop the MS IM Speak and use the language of the forum. In this forum it is English, which is successfully used by many people for whom English is far from their native language.

An error has occurred while accessing SQL database or system resources. If this is the first time you have seen this message, please try again later. If this problem persists, please contact your administrator.

I have SP Server 2010, and when I try to DELETE a rule within an existing Audience, "Property (Account Name) = domain/username", I get this error, "An error has occurred while accessing SQL database or system resources. If this
is the first time you have seen this message, please try again later. If this
problem persists, please contact your administrator." When I try to "MODIFY" the rule I get this error, "One or more values typed on this page are not valid. Check the text for the indicated fields."
The last time I checked it was working, I'm not aware of any new updates installed recently? I did a full Profile Synchronization as well, but still not working, please advise? -- Evenstarline

Hi Sara,
First of all thank you very much for your prompt responses. Here are my comments to each of your suggestions below, and just to let you know I am using a Farm Admin account.  I
was able to do this way after we upgraded from SP 2007 to SP 2010 as well.   I would like to mention I'm not a SP expert, just been given the responsibility due to another person handling it just left, so apologize with some of
my novice questions below?
1. When I change the Operators to "Contains" or "Not Contains" get generates this error below.
     Error generating in red towards top of the audience page..."One or more values typed on this page are not valid. Check the text for the indicated fields."
     Error occurred where you enter your "Value"..."Could not resolve the user identity. Please re-enter the account name."
2. We have a 3-server-tier topology (SPWeb, SPDB, and SPFarm). Does the updates only apply to where the Central Admin is installed, which is the "SPFarm"? I checked all
3 servers, and NONE of the updates (KB2899494, KB2889845, and KB2883055) you'd mentioned are installed.
3. I'm new to IISRET, I need to be extra cautious of what I run in production, is this safe to run with no problem? What does it do? And How do I run it?
4. I'm also new to viewing the ULS log. I'd just downloaded a viewer for it. I'm assuming the only logs I need to be concern with viewing are within the SPAdmin (where Central
Admin is installed)? There's so many of them, what should I be looking for exactly?

How to access multiple database present in single instance

Hi Team,
In oracle 11.2, can there be multiple databases in an instance??? In one of our environment, I could see multiple databases in an instance. Could you please help me in giving the data dictionary or query to access those databases?
Actually, querying v$database, I could see only one database which is same as instance name. But in inventory, there are multiple database in an instance?
I am still not exactly clear about this. Can someone help me with this?
Thanks!
Vidhya

In Oracle one instance manages one (1) database. A database consists of multiple *schemas*.
Other vendors erroneously call a schema 'database'.
So, no, you didn't see multiple databases.
There is also one datadictionary, consisting of a set of views.
All views beginning with dba_ list the entire database, all schemas.
All views beginning with all_ list the objects you have access to.
All views beginning with user_ list your own objects.
The view DICT show you the contents of the datadictionary.
Oracle also has online documentation at http://docs.oracle.com
From your question it is clear you should read the document called the 'Oracle Concepts Manual'.
You can find all documentation for 11gR2 here Oracle Database Online Documentation 11g Release 2 (11.2)
Too many people here don't make any effort to read it. This is probably the reason why you got no response.

Not able to access the Database & Clusterware from OEM Console.

hi,
I had installed Oracle RAC 11g R2 in RHEL 5.3 Operating environment. I had installed my Oracle RAC with Enterprise Manager Console.
Its with the defailt port 1158. After the installation when i try to access my EM Console, i was not able to access the Database and Clusterware from EM Console.
When i access the EM console with url, I found with Startup and Perform Recovery option. But whereas my database is already startup and running.
So when i click startup its saying database is already started. Since it is a prodution environment i dont want to go with Perform recovery option.
Please tell me hw to attach files in this thread so that i can send the snap shot of the console for your reference.
with regards

hi,
As mentioned due to not having the default listener port 1521, we are facing this problem.
As meniotned i had changed the emoms.properties file and changed the port and my emctl page is opening.
But am not able to access the other parameters like ASM, Servers, Clusters etc bcoz since in some file it is looking for 1521 default port.
So is it better to go for emctl deconfig and config again or to change the port the files which required.
If i do in what are the file the default port will be located related to emctl.
with regards
