(教學)在Ubuntu裡建立Apache with Tomcat 服務-3

前二篇資料(教學)在Ubuntu裡建立Apache with Tomcat 服務-2    (教學)在Ubuntu裡建立Apache with Tomcat 服務-1

讓Apache Server與Tomcat Server做溝通

使Apache支援JSP及測試ImageMagick及JMagick是否可用

1.設定apache使用apj與tomcat做溝通,把所有內容向tomcat送

#sudo vi /etc/apache2/sites-available/default
在<VirtualHost *:80></VirtualHost>tag內增加

        LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
        LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
        LoadModule proxy_connect_module /usr/lib/apache2/modules/mod_proxy_conn$
        LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so
        ProxyPass / ajp://127.0.0.1:8009/
        ProxyPassReverse / ajp://127.0.0.1:8009/

2.重新啟動tomcat及apache

#sudo /etc/init.d/tomcat5 restart
#sudo /etc/init.d/apache2 restart
測試http://localhost/是否跟http://localhost:8080/一樣

一樣的話就是成功了!

3.測試jmagick是否可用




#sudo vi /etc/tomcat5/webapps/ROOT/testimage.jsp

        javax.imageio.ImageIO.write(bimg,"jpg",f);
        bs.close();
    }catch(java.io.IOException e)
    {
        throw e;
    }
    finally
    {
        try
        {
            if(bs!=null)
            {
                bs.close();
                bs = null;
            }
        }catch(java.io.IOException ex)
        {
        }
    }
}
if (System.getProperty("jmagick.systemclassloader") == null) {
    System.setProperty("jmagick.systemclassloader", "no");
  }
  magick.ImageInfo info = new magick.ImageInfo(strAbsPath+"/test.jpg");
  magick.MagickImage image = new magick.MagickImage(info);

//resize image

magick.MagickImage scaleImg = image.scaleImage(65, 46);
scaleImg.setFileName(strAbsPath+"/test2.jpg");
scaleImg.writeImage(info);

如果可以看到一個大圖一個小圖那就是沒問題了
