MS Access and Java JDBC help!

Hello, I having trouble with a java GUI.
I have a MS Access named Database.mdb with a table named Customer which I want my GUI to access.
I want my GUI to be able to flick through the records using the field I have made for them.
I already have connected the database using windows xp's "System DSN" and have no problem creating tables using sql statements in my code
Who can help me? any information would be great.
Thanks

is there any way that i can use void functions in my output? or would i need to change to a method that returns a value?
here is my code, please help me, it will be greatly appreciated :)

Vista, Access, and Palm ZZ--help!!

Hello. I have had my palm for almost 3 years. Just recently I had a blob on my calendar. To fix that I had to download Access, since I have Windows Vista. It is working fine now, but how do I put photos on my palm? I used Splash Photo before, but now have media on Access. I have the photos on the Palm Desktop, but when I try to move them to install it says it is not supported. Is the install tool not compatible with Vista? It was my understanding that that is what Access is for. Please help me!!
Post relates to: Palm Z22
This question was solved.
View Solution.

You need to install the spash photo on the PC so the conduits in the Hotsync manager and be updated to sync photos. You will need your Z22 CD.
Put the CD in. It should try to install if it does just cancel it if not don't worry less for you to do.
Next you want to go into your computer. From there right click on the CD ROM drive and either click open or explore.
Then select English.
Then Photos.
Then double click on splashphoto.exe.
then you should be able to sync your photos.

Accessibility and Java GUI testing

Hi,
Can java accessibility be used for developing java GUI testing tool for applet embedded in IE? If not is there any other way we can test Java Appet GUI?
best regards

I do not know of a free tool, but you can use the Robot class in Java to create what you need.

How can I access my java class file in a .jar file ...PLz Help anyone!!

Hi Folks,
I am new in Java programming, have a .jar file that contains .java files that I want no access and use from another .java file. These files in the .jar file basically form a library thus have no main-method. However I can not declare an instance of the library (in the .jar file) and use it within my program.
Plz help ...I have tried all I know in vain.
Thanks.

Jdbc and java stored procedures

Hi all,
I am new to Oracle Java Stored Procedures but I am interested in knowing to which extent is object passing supported.
Can I send any kind of object to a java stored procedure? And back from the procedure? Anybody knows any good resources online about Java Stored Procedures and JDBC?
I also saw that to pass the string back you need to specify java.lang.string, how would I do in order to pass back a user defined object, do I have to register the class in Oracle before (and if yes, how?)or is the classpath enough?
Many thanks,
A.

Hi again,
perhaps I didn't understand exactly what you meant with "publish", AFAIK you have to expose the java class (i.e. RowCounter) by using
CREATE OR REPLACE FUNCTION row_count (tab_name VARCHAR2) RETURN NUMBER
AS LANGUAGE JAVA
NAME 'RowCounter.rowCount(java.lang.String) return int';
(BTW this works fine)
or else you cannot access the java class you loaded on the server, and that's where my questions arose. What if I am passing an object, let's say myObject, shouldn't I use the STRUCT mapping then or something like that?
Or, could you clarify what do you mean by publishing to SQL, I just need to access the class from jdbc, not from PL/SQL or others, but as I understand to call the class from JDBC I need to call the function or procedure that calls the class and then I could call it from PL/SQL as well...
Thanks,
A.

Why signed and get "access denied (java.io.FilePermission hello.txt read)"?

I am learning the Java tools and policy to create some local browser application for personal use. So I signed a jar file with jarsigner, keytool and policytool and still trying to figure out why my browser application cannot read a simple local text file.
My question are
1. Why use java policy tool (policytool.exe)? If I signed a .jar with keytool and jarsigner, do I really need java policytool to write a policy?
2. What is the maximum validity days? 365? or more? Do I need to sign again when validity expire?
3. I don't want any of my local browser application gets to internet but only work with local files (read, write, or execute). how do I do that?
4. how to use java security policy to grant access to the jar applet? where do I place and import the policy file so the hosting web browser and the applet can work?
My java applet is a simple class that read a text line from a local file in the same folder, and pass the result to a calling web browser Javascript.
Currently the result in the web page is the error message below, even though the jar is signed correctly.
access denied (java.io.FilePermission hello.txt read)
Someone please help and enlight the newbie!

.. So I signed a jar file with jarsigner, keytool and policytool and still trying to figure out why my browser application cannot read a simple local text file.
My question are
1. Why use java policy tool (policytool.exe)? If I signed a .jar with keytool and jarsigner, do I really need java policytool to write a policy?No. In fact, don't stuff around with policy files - they are a path to madness.
2. What is the maximum validity days? 365? or more?Keytool accepts an argument for the number of days to remain valid. I do not believe it has an upper limit, but it might be best to experiment with it and find out for yourself. Please report your findings back.
(2a) Do I need to sign again when validity expire?No, but the end user gets a huge warning that the certificate has expired. Further, if it was a certificate that was certified by a CA, the 'always trust' check box which used to default to true, would now default to false.
3. I don't want any of my local browser application gets to internet but only work with local files (read, write, or execute). how do I do that?I am not sure I understand, but if you only offer a JFileChooser for the applet to access resources, that should restrict it to resources off the local file-system. Of course, that would not restrict the end user from downloading something from the internet to their local disks, then accessing it using the applet.
4. how to use java security policy to grant access to the jar applet? where do I place and import the policy file so the hosting web browser and the applet can work?The only place it will work is in the JRE directories of the end-user's machine. Even if you find a way to install your local policy file, do not go messing with the end-user's policy files.
My java applet is a simple class that read a text line from a local file in the same folder,.. In the 'same folder' as what? (1)
..and pass the result to a calling web browser Javascript. That might be the problem. AFAIR, using JS with trusted applets causes the security to be tightened. Perhaps it could be fixed by calling System.setSecurityManager(null) on applet init(), but I have also seen references to using [AccessController.doPrivileged()|http://java.sun.com/j2se/1.4.2/docs/api/java/security/AccessController.html] to wrap the problematic code. I am hazy on the details of how/if that works.
Currently the result in the web page is the error message below, even though the jar is signed correctly.
access denied (java.io.FilePermission hello.txt read)
1) If the answer to my question is what I suspect, there may be better ways to access the resource that are usable even in a sand-boxed app.

Applets are not allowed to connect to other server
than the one they were loaded from. This is probably
the reason here.You mean that I can use the applet after uploading on my web-site and using "getDocumentBase()" only?
OK.
The applet works perfectly if I use that function, but I have another question.
If I want to use something like:
Img1=getImage(getDocumentBase(), "s01.jpg");
it works perfectly.
If I do the fillowing:
Img1=getImage(getDocumentBase(), "pic/s01.jpg");
it also works.
But is it possible to go a level up?
Like:
Img1=getImage(getDocumentBase(), "../pic/s01.jpg");
That is if an applet is in one folder and the pictures are in another, but to get to them I have to go a level up and then enter another folder.
Please help.
Thanks.

Q: How to access and modify xml tags using Java

I have an xml based document that i need to access and change. For example, the code
<section id="section1">
<div>
<xforms:group id="id1">
<xforms:label id="label1">
<l style="font-size:16pt"> something </l>
</xforms:label>
</xforms:group>
</div>
</section>
Working with Java I need to access all the tags, select some of them that are relevant to the current device and remade the document. I thought I would read the file character by character identifying the different labels and building a tree, storing in the tree nodes the relevant information as some kind of attributes (for example, in the case of the <xforms:group id="id1"> I would name the node "xforms:group" and create an "id" attribute with value "id1"). I'm not sure if that is the most efficient way of accessing the problem (computational power might be an issue), and would appreciate some help on the subject.
Thanks,

this may help you..
this is a little util i made to help me read/write files.
using this, you are only one step away from your solutions, you only need to figure out the regex you need to run on the text of the file to make it become what you need it to become.

Access denied java.lang.RuntimePermission accessClassInPackage.sun.jdbc.

When i am running my applet program with database the following message is displayed in command prompt .
" access denied <java.lang.RuntimePermission accessClassInPackage.sun.jdbc.odbc> "
Above program is running fine without applet i.e. normal java application

@OP
Well this is bound to happen my friend..In general are designed to be more secure & don't have adequate access to System(Fils,Audio,SSL,Native Code,Database.. & etc) resources.
Well need sign the applet inorder to do that.
you may go through the link given below to which provides details about siging an applet.

(An advice)It is not a gud practise of using vunerablities where there is a security restrcition... we might quite often mishandle resources in this case.
Hope this might be of some help :)

J2me and java card, need help to communicate

we are trying to put together a reader to read smartcards using j2me and we figure that it would be easiest if we could develop it to work with java cards rather than standard smart cards, the problem is we get garbage when we communicate to it, the chip sends us crap, any suggestions what might be wrong, any calls we might be missing, has anyone worked with j2me and java cards or smart cards, any help would be appreciated.

.... reader app and the ME behind it .... smells like mobile ....
First of all - if you want to have one mobile application running on this just make sure that whatever is written in ME can use drivers from the reader chip ....
Workin on the PC is something completely different. There was one good example how to develop one host application in Java provided with the JCOP tools long ago ... I don't know if this is now in the new Eclipse tools.
But - there was a small API provided that can give you good hints what to do - and - once you have it on the reader side - you can easily integrate ME methods with this ...

I continually get a Java error. I've uninstalled and reinstalled firefox and nothing has helped. I've updated flash and Java.

I have used Firefox as my default browser for many years. I've recently started getting a Java error message. It pops up continually. I have updated flash and java. I have uninstalled and re-installed Firefox and nothing has helped. I have had to start using Chrome instead of Firefox which I don't care for but I don't have the java error with Chrome. How do I fix this problem? The error reads as follows:
Java Script Application
Error: syntax error

Your '''JavaScript''' error has nothing to do with the Java plugin . It is likely caused by an added extension (the earlier forum threads [/questions/944619] and [/questions/943088] mention disabling or updating the Social Fixer extension will resolve the problem).
You can read this article for help troubleshooting your extensions: [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
