Hi Friends....

I have questions...

Can we password protect a file / folder / drive (Pen drive or c: / d: drive of windows) using java?

I can zip and password protect a file and folder, but its actually creating the copy of original data....

can we password protect file / folder without zipping them?
can we password protect pen drive or windows drive?

Awaiting your response...

Thank you..

Hi,
i have created a project for my MCA 6th semester.
My question is how can i package My web application and Derby database together, so when i take it with me on presentation, it will be easy for me to present it,

because when i open my project on other computer, i can easily open the web application, but to make it fully functional, i need to create the database and and tables in it for every computer.

is there any way that database can go with project, and open with it.

Please help !!

Thank you

I am also getting the same error. aren't there any way around it. can't we store image on the database at all???
hi friends,
I want to store images (.jpg or .png or .gif) in MS SQL Server 2005 database using JDBC-ODBC connectivity in servlet. can anybody give me step by step procedure to do it.
I don't wan't to store the reference to images, instead i want to store actual image file in a database.

Please give me step by step procedure to do it.

Thank You
i found the way around it. i removed the Apache tomcat server form netbeans server list and added it again. by doing this the tomcat-users.xml file content been deleted automatically and when i add the tomcat again i also created the user using netbeans and after that it works. before i edit that tomcat-users.xml file manually but i won't work, but by editing it with netbeans it works.
now tomcat is using 8080 port instead of 8084.

tomcat manager is working now.

I can live without admin console, i asked it because when we right click and click on view admin console it point to localhost:8080/admin page when returns 404 error. when apache tomcat remved the admin features from 6th version then why it point to that same location.

anyways my problem get solved. i don't know there is some kind of magic in this blog whenever i stuck with something and post my problem here, my problem get solved always.

Thank you very much

hi friends,

Today i installed netbeans 6.7 with glashfish v2.1 and Apache Tomcat 6.0.18. I created an web application using Apache Tomcat as a webserver.

I am not able to access Apache Tomcat admin console. here is the steps i used to access admin console of tomcat:

1. click on service tab of netbeans IDE 6.7.
2. expand servers and right click on Apache Tomcat 6.0.18 and click start.
3. after the server starts. right click again on apache tomcat 6.0.18 and click on view admin console.
4. it opens a web browser with "http://localhost:8084/admin" url. and giving error "HTTP Status 404 - /admin".
5. when i open it using "http://localhost:8084/" it shows home page of Apache Tomcat Server.

6. when i try to access administration links like status and tomcat Manager, it asks for password (what is the default user name and password to access it).

7. when i click cancel on it . it says:

You are not authorized to view this page. If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file will contain the credentials to let you use this webapp.

You will need to add manager role to the config file listed above. For example:

<role rolename="manager"/>
<user username="tomcat" password="s3cret" roles="manager"/>


8. so i opened that file and tried to use the predefined users like username=tomcat password=tomcat, but it still says you are not authorized. so by following the above message I created a role manager and create a user in that account. but i am still not able to open its admin page.

Please suggest me what to do. because when i installed netbeans it asks for default user name and password for glashfish webserver, but not for Apache tomcat.

Please guide me so i can access the admin page of tomcat.

Thank you

Hi friends, i am working on my college project. My project is working perfectly. i used JDBC-ODBC bridge driver. but my teachers says that this driver is very useful for testing, but not for normal use, i.e., when we deploy our application to the web server over the internet, its not a good idea to use JDBC.ODBC bridge driver. Instead we should use JNDI driver.
Is this true?
I don't know much about JNDI connectivity. i am able to connect Derby database using the JNDI. but how to connect to SQL database using NetBeans IDE (i am using 6.5).
My teachers have no idea how to connect to SQL database using JNDI. whenever i ask them about it they say to connect to the SQL server we need to install a driver in NetBeans. they always say that.
Can/t we connect to SQL database using JNDI in NetBeans IDE 6.5 without installing any extra driver?

Please help me i don't know much about JNDI connectivity to SQL Database. will anyone give me some example or tutorial link.

I sent the complaint to sun's inquiry suggestion section. lets wait for their reply!!!
