(1) Javaの設置
jarファイルで設置も考えましたが、変更もあり得るのでそのまま設置しました。
今回は以下を設置しました。
https://github.com/smzn/Sentiment
今回は外部jarファイルがあるので、/usr/local/lib にjarファイルを入れておき
$ vi ~/.bashrc
export CLASSPATH=/usr/local/lib/mysql-connector-java-5.1.45-bin.jar:/usr/local/lib/io.indico-3.15.0.jar:/usr/local/lib/io.indico-3.15.0-jar-with-dependencies.jar:$CLASSPATH
と設定しました。
実行できることを確認します。
(2)シェルスクリプトの作成
シェルスクリプトを作成し、置いておきます。クラスパスは必要です。
$ vi ~/indico/sentiment.sh

| cd /home/ms000/indico | |
| javac sentiment/*.java | |
| java sentiment.Sentiment_main |
$ chmod +x ~/indico/sentiment.sh
シェルスクリプトから実行できることを確認します。

#!/bin/sh export CLASSPATH=/usr/local/lib/mysql-connector-java-5.1.45-bin.jar:/usr/local/lib/io.indico-3.15.0.jar:/usr/local/lib/io.indico-3.15.0-jar-with-dependencies.jar:$CLASSPATH cd /home/ms000/indico javac sentiment/*.java java sentiment.Sentiment_main
PHPから呼び出すときに、exec関数を利用します。

| public function sentiment($id = null) { | |
| if (!$this->Keyword->exists($id)) { | |
| throw new NotFoundException(__('Invalid keyword')); | |
| } | |
| $options = array('conditions' => array('Keyword.' . $this->Keyword->primaryKey => $id)); | |
| $cmd = 'sh /home/ms000/indico/sentiment.sh'; | |
| exec($cmd, $opt); | |
| //print_r($opt); | |
| $this->set('keyword', $this->Keyword->find('first', $options)); | |
| } |
これでPHPからJavaを実行できました。
