Linux Permissions

It doesn't belong here ... but was worth sharing.

• chmod /*change the permissions of a file*/
• chown /*change the owner of the file*/
• chgrp /*change the group that the file belongs to*/

example:
chmod 777 somefile.file /*this gives exe write and read to all */ not recommended for any file.

For chmod here is a list of the numbers and what they mean

• the 100's are for the owner of the file

400 reed
200 write
100 execute

• 10's are for the group of the file

40 read
20 write
10 execute

• 1's are for everyone else

4 read
2 write
1 execute

you add the number together to get different permissions

jdbc:microsoft:sqlserver://:[;DatabaseName=]
com.microsoft.sqlserver.jdbc.SQLServerDriver

MySQL (MM.MySQL Driver)
jdbc:mysql://:/
org.gjt.mm.mysql.Driver

Oracle OCI 8i
jdbc:oracle:oci8:@
oracle.jdbc.driver.OracleDriver

Oracle OCI 9i
jdbc:oracle:oci:@
oracle.jdbc.driver.OracleDriver

PostgreSQL (v6.5 and earlier)
jdbc:postgresql://:/
postgresql.Driver

PostgreSQL (v7.0 and later)
jdbc:postgresql://:/

Sybase (jConnect 4.2 and earlier)
jdbc:sybase:Tds::
com.sybase.jdbc.SybDriver

Sybase (jConnect 5.2)
jdbc:sybase:Tds::

To test your driver once it's installed, try the following code:

{
Class.forName("Driver name");
Connection con = DriverManager.getConnenction("jdbcurl","username","password");
//other manipulation using jdbc commands
}
catch(Exception e)
{
}

Removing the Extra Fat - JBoss

You can remove the following components:

• AOP Application
• Cache invalidation service (keep for a clustered installation)
• Console/e-mail monitor alerts
• CORBA/IIOP
• HTTP Invoker
• Hibernate session Management services
• HSQL DB
• Integrated HAR deployer
• J2EE client deployer service
• JBoss scheduler manager
• JMX Console
• Mail service
• Management console
• Sample Schedule service
• Scheduler service
• Test queues and topics
• UUID key Generation
• Web services support

You can remove all or selected ones depending on what services of JBoss your application will be using. Generally applications have their own implementation of Schedulers, Mail services Queues etc. but if you are dependent on JBoss's implementation then choose wisely.

How and What to remove:

For removing the ones listed above you need to take care of their dependencies else JBoss will be sad and fill your log.

SSL and JBOSS : Baby Steps

I am not sure how many of you have visited http://24x7-java.blogspot.com/ and felt good.

You'll find lots of pages describing the process of enabling ssl on JBoss, but many of them explain in a way which it too technical. The intention here is to let everyone do it easily (on windows OS).

So describing it in baby steps

Q. What you need?

A. JDK and JBoss

Step 1. Open command prompt and goto bin directory under JDK (not jre) and execute

keytool -genkey -alias tomcat -keyalg RSA

(if you have JAVA_HOME/bin in your system path then you can just execute the above command on the prompt ).

You'll be prompted for the following and fill as per your need.

Enter keystore password:
Re-enter new password:
What is your first and last name?
[Unknown]: Sunil

What is the name of your organizational unit?
[Unknown]: development

What is the name of your organization?
[Unknown]: test

What is the name of your City or Locality?
[Unknown]: Shimla

What is the name of your State or Province?
[Unknown]: HP

What is the two-letter country code for this unit?
[Unknown]: IN

Is CN=Sunil, OU=development, O=test, L=Shimla, ST=HP, C=IN correct?
[no]: Yes

Enter key password for
(RETURN if same as keystore password):

Keep the key password same as your keystore for ease.

Step 2. Copy the default keystore created in your C:\Documents and Settings\<currently-loggedin-user>.keystore
to
<drivepath>:\jboss\server\default\conf and rename it to my.keystore

Step 3. Edit file
<drivepath>:\jboss\server\default\deploy\jboss-web.deployer\server.xml or
<drivepath>:\jboss\server\default\deploy\jbossweb-tomcat55.sar\server.xml depending on the version of jBoss and make the following changes.

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false"
strategy="ms"
address="${jboss.bind.address}"
keystoreFile="${jboss.server.home.dir}/conf/my.keystore"
keystorePass="keypassword"
truststoreFile="${jboss.server.home.dir}/conf/my.keystore"
truststorePass="keypassword"
sslProtocol="TLS"/>

Step 4. Start you jboss run -c default and thats all. Your application will now be avaliable on both http:// and https:// . If you want to disable http:// Comment the tag below in server.xml

<Connector port="80" address="${jboss.bind.address}"
maxThreads="250" maxHttpHeaderSize="8192"
emptySessionPath="true" protocol="HTTP/1.1"
enableLookups="false" redirectPort="443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />

The Connector port is by default 8080.

Will Oracle kill Java Community

I spent my few hours going through various forums and reading about the after effects of the one of the biggest mergers in software industry, Oracle's acquisition of Sun. There were concerns which made me think too.

1. Will MySQL die ?
   Being Database giant will Oracle support MySQL or silently kill it. The database market is currently ruled by three major companies - IBM, Microsoft and Oracle - controlling 85 per cent of the market in revenue terms and Sun's MySQL (free and open source) will extend further into Oracle's market as its functionality improves. So why will Oracle support it?
   
   
2. Future of GlassFish ?
   Will GlassFish become extinct? Oracle already sells WebLogic (after it acquired BEA Systems) and Oracle Application Server. Oracle may say no to support GlassFish project as it already has to support two identical application servers.
   
   
3. What will happen to NetBeans?
   Oracle is a strong supporter of Eclipse so NetBeans might die with time as well.
   

Oracle has to get everyone together as soon as possible to spell out their future plans for Java Community. If Oracle doesn’t, they’ll have Java developers running, not walking, away from the Sun/Oracle Java as fast as they can.
