Tomcat Installation and Setup on Windows [relevance: 1.49]

2007-09-13

make sure the file msvcr71.dll is present in the system path
intall java jre
install tomcat
copy the deployment directory onto the local drive
edit:
..\Apache Software Foundation\Tomcat 6.0\conf\server.xml
to include the deployment path to the application
this looks like this and should sit inside the following heirachy within the xml document
<Server>
<Service>
<Engine>
<Host>
<Context path="/Project" reloadable="true" docBase="C:\Project" workDir="C:\Project\work" />
</Host>
</Engine>
</Service>
</Server>
edit:
..\Project\WEB-INF\web.xml
to make sure the logging directories are set up correctly etc (packages etc)
launch tomcat and deploy the project from the project manager
it should now be available at http://localhost:8080
run emulate from the run.bat batch file - making sure its pointing to the right target within the batch file

Installing Java on Linux [relevance: 1.48]

2007-08-31

Install:

chmod +x jdk-6u2-linux-i586-rpm.bin

./jdk-6u2-linux-i586-rpm.bin

Follow prompts [yes]/[no] etc

If it gives the error message

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

Then you have to download

compat-libstdc++-33-3.2.3-47.fc4.i386.rpm

which can be found

ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/

or by googling it

rpm -i compat-libstdc++-33-3.2.3-47.fc4.i386.rpm
or # yum install libstdc++.so.5

The SDK installed in /usr/java/jdk/

add path to $HOME/.bash_profile

PATH=/usr/java/jdk/bin:$PATH:$HOME/bin:./

export PATH

export JAVA_HOME=/usr/java/jdk

export CLASSPATH=/usr/java/jdk/lib/tools.jar:/usr/java/jdk/jre/lib/rt.jar:./

Possible Issues

When installing Jboss 4.2.1.GA it throws a fit if you have anything less than Java 1.6 JRE and the 1.5 JDK installed - Centos installs it's own version of Java 1.4 to fulfil install dependencies and this seems to conflict with the Sun versions - make sure you uninstall GNU Java 1.4 from the package manager or any other way you fancy and then install first the 1.6 JRE followed by the 1.5 JDK. After that you can just drag a copy of Jboss onto the linux box and start it with /bin/./run.sh & (to spawn a process)

Bluetooth connection manager in Mobile Java J2ME [relevance: 1.17]

2009-03-17

This Bluetooth Java connection manager class and its data package class have quite a few issues - main one being that the thread for checking the incoming data stream should be reading each byte of data and queuing it rather than trying to receive discrete packages of data and queueing them - will be fixed and updated at some stage.

cnnet.hk scam [relevance: 1.07]

2007-12-03

If you receive email from cnnet.hk purporting to be from the main domain name registrar in China be very sceptical. China's main registrar is http://www.cnnic.net.cn/ and this company appears to be some sort of dodgy scam set up to obtain private information.

Here is an example of an email received from cnnet:

Dear Manager,

We are China Net Technology Limited, which is the domain name register center in China.I have something need to confirm with you.

we have received an application formally,one company named "Worldpro Investment Limited" applies for the domain names( ...biz\....cn\....com.cn\....net.cn\....tw\....com.tw\....hk\....mobi etc.) and the internet Brand Name(...)on the internet Dec 3. 2007. We need to know the opinion of your company, because the domain names and keywords may relate to the usufruct of brand name on internet.

we would like to get the affirmation of your company,please contact us by telephone or email as soon as possible. Please let someone in your company who is responsible for trademark or intellectual right contact me freely.
