Coding Java Linux

Eclipse and Ubuntu 8.04

I was having some trouble running Eclipse 3.3 Europa on Hardy Heron.  It was unstable, crashing a lot, and hogging way more ram than it normally hogs.

Then I realized what I’d forgotten to do on this fresh install.  I forgot to simply ‘sudo update-java-alternatives -s java-6-sun’ and voila, it works like a charm.

Eclipse doesn’t work well with the gjc java (the ‘free’ and default) Hopefully this little thing won’t be an issue in the future when sun java 7 (open java) is ready to rock the free world.


Subversion on the Mac

Why does subversion on the Mac have to suck so bad?

Sure there’s apps, SvnX, SCPlugin for Finder, and a few others that typically suck — and unfortunately I always end up using Eclipse and it’s Subversion plugin.

But really, the user friendliness of it all is making my stomach turn.

Coding Java Linux PHP

Installing PHP Java Bridge on Ubuntu

Source Install

First, make sure all php packages are updated — if you update PHP after installing this, it will likely segfault.

For the purpose of this, I’m using Ubuntu 7.10, and Java 6 (sun-java6)

First, get the build essential, as well as php5-dev, sun java and automake

# apt-get install build-essential php5-dev sun-java6-jre \
    sun-java6-jdk sun-java6-source automake

Second, get the PHP/Java bridge source.

# cd /usr/src
# wget
# tar xzfv php-java-bridge_5.2.0.tar.gz

And, install.

# cd /usr/src/php-java-bridge-5.2.0
# phpize
# ./configure --with-java=/usr/lib/jvm/java-6-sun-,/usr/lib/jvm/java-6-sun-
# make
# chmod +x
# ./

Answering the questions for the install script is fairly simple. It looks for some tomcat stuff for the servlet portion of the Java Bridge, but we won’t be using it.

Copy *.inc to someplace it can be found.

# mkdir /usr/share/php/java
# cp *.inc /usr/share/php/java


# php test.php

By default, java is only enabled in the command line php; to enable it in the global instances of php, edit the php.ini file and add the extension.

;; java.ini: Activate the PHP/Java extension

;; zend_extension = "/path/to/"
extension =

;; If you have installed the java-servlet.ini leave this file alone,
;; edit the servlet or standalone ini file.  Otherwise uncomment the
;; following java section and one of the following options:

There are no other options required. Make sure the java.hosts and java.servlet are disabled. If logging is desired, that’s another story.
