Background Slide di Ubuntu

Hi all..
Ternyata kita bisa membuat background slide di Ubuntu seperti yang ada pada Windows 7.
Ini cara membuatnya :

1. Masuk sebagai root (alt+F2)
2. Ketik : (gksudo nautilus)
3. Buat sebuah folder untuk tempat gambar - gambar yang akan di buat slide (tempat
terserah anda)
4. Copy gambar - gambar yang akan di buat slide ke folder tersebut
5. Buat sebuah file document di dalam folder tersebut dan beri nama background-2.xml
(nama file terserah anda) lalu save file tersebut dengan ext .xml
6. Buat script di file tersebut seperti ini :

<background>
<starttime>
<year>2009</year>
<month>08</month>
<day>04</day>
<hour>00</hour>
<minute>00</minute>
<second>00</second>
</starttime>
<!-- This animation will start at midnight. -->
<static>
<duration>1795.0</duration>
<file>/usr/share/backgrounds/gambar/013762.jpg</file>
</static>
<transition>
<duration>5.0</duration>
<from>/usr/share/backgrounds/gambar/013762.jpg</from>
<to>/usr/share/backgrounds/gambar/death_note_back.jpg</to>
</transition>
<static>
<duration>1795.0</duration>
<file>/usr/share/backgrounds/gambar/death_note_back.jpg</file>
</static>
<transition>
<duration>5.0</duration>
<from>/usr/share/backgrounds/gambar/death_note_back.jpg</from>
<to>/usr/share/backgrounds/gambar/FelixTheCatWallpaper1024.jpg</to>
</transition>
<static>
<duration>1795.0</duration>
<file>/usr/share/backgrounds/gambar/FelixTheCatWallpaper1024.jpg</file>
</static>
<transition>
<duration>5.0</duration>
<from>/usr/share/backgrounds/gambar/FelixTheCatWallpaper1024.jpg</from>
<to>/usr/share/backgrounds/gambar/013762.jpg</to>
</transition>
</background>

<duration>5.0</duration> ( itu menyetting durasi waktu slide nya bisa
disesuaikan dengan keinginan anda )
<from>/usr/share/backgrounds/gambar/FelixTheCatWallpaper1024.jpg</from>
( itu untuk alamat file gambar awal anda )
<to>/usr/share/backgrounds/gambar/013762.jpg</to>
( itu untuk alamat file gambar lanjutannya )

7. Save
8. Buka System >> Preferences >> Apperance >> Background >> Add (All
Files) >> pilih file .xml tadi >> Open
9. Close Selamat mencoba..!!

Cara membuat variabel di velocity

Ni hanya pengalaman saja.
Awalnya saya juga kesulitan dan bingung, bagaimana ya caranya membuat variabel di velocity???
Terus dari mencoba - coba dan akhirnya ketemu juga..

Ini contoh source code-nya :

#set ($n = 0)
#set ($data = "Riza")
#set ($n = $n + 1)

No : $n
Nama : $d


Kalau di java itu akan sama dengan :

int n = 0;
String data = "Riza";
n = n + 1;

Terima kasih telah membaca, bila ada kekurangannya saya mohon maaf..

Reporting In Java

Untuk membuat report dibutuhkan library;

cimande-2.0.jar
commons-beanutils-1.8.0.jar
commons-collection-3.2.1.jar
commons-disgester-2.0.jar
commons-logging-1.1.jar
commons-io-1.4.jar
groovy-all-1.5.5.jar
iText-2.1.7.jar
jasperreport-3.7.5.jar
rhino-1.7R1.jar
struts2-jasperreports-plugin-2.1.8.1.jar
(Library sesuaikan dengan versi iReport anda)

Setelah itu ikuti langkah"-nya..

Buat Kelas MyIO
import java.io.File; import java.io.IOException; import java.net.URL; import java.security.CodeSource; import java.security.ProtectionDomain; public class MyIO{ public static File getBaseFolder() throws IOException { ProtectionDomain domain = MyIO.class.getProtectionDomain(); CodeSource source = domain.getCodeSource(); URL url = source.getLocation(); if (!"file".equals(url.getProtocol())){ throw new IOException("Code source location not a file:" + url); } String path = url.getPath().replaceAll(" ", " "); return (new File(path.substring(0, path.lastIndexOf("/WEB-INF/")))); } }

Buat Kelas Untuk Reportnya import java.io.File; import java.io.FileInputStream; import java.sql.Connection; import java.sql.DriverManager; import java.util.HashMap; import org.blueoxygen.cimande.commons.CimandeAction; import net.sf.jasperreports.engine.JRExporter; import net.sf.jasperreports.engine.JRExporterParameter; import net.sf.jasperreports.engine.JasperFillManager; import net.sf.jasperreports.engine.JasperPrint; import net.sf.jasperreports.engine.export.JRPdfExporter; import net.sf.jasperreports.engine.export.JRRtfExporter; import net.sf.jasperreports.engine.export.oasis.JROdtExporter; public class Cetak extends CimandeAction { String fileType="pdf"; String fileURL="riza"; Sstring id_="1"; public String execute() { try { final String outPath = MyIO.getBaseFolder().getPath(); File file = new File(outPath + "/jasperFolder/" + getFileURL() + ".jasper"); HashMap map = new HashMap(); map.put("ID", getId_()); /* * Untuk membuat kondisi di HashMap langsung aje */ /* * Buat koneksi yang sama seperti pada report */ String url = "jdbc:mysql://localhost:3306/Jasper"; Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection(url, "root", ""); if (con != null) { System.out.println("koneksi " + con); } else { System.out.print("tidak konek"); } JasperPrint jasperPrint = JasperFillManager.fillReport( new FileInputStream(file), map, con); JRExporter exporter = null; if ("pdf".equalsIgnoreCase(getFileType())) { response.setContentType("application/pdf"); response.setHeader("Content-Disposition", "attachment;filename=" + "\"" + getFileURL() + ".pdf" + "\""); exporter = new JRPdfExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream()); exporter.exportReport(); } else if ("rtf".equalsIgnoreCase(getFileType())) { response.setContentType("application/rtf"); response.setHeader("Content-Disposition", "attachment;filename=" + "\"" + getFileURL() + ".rtf" + "\""); exporter = new JRRtfExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream()); exporter.exportReport(); } else { response.setContentType("application/vnd.oasis.opendocument.text"); response.setHeader("Content-Disposition", "attachment;filename=" + "\"" + getFileURL() + ".odt" + "\""); exporter = new JROdtExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream()); exporter.exportReport(); } } catch (Exception e) { String connectMsg = "Could not create the report " + e.getMessage() + " " + e.getLocalizedMessage(); System.out.println("\n" + "\n" + connectMsg); return ERROR; } return SUCCESS; } public String getFileType() { return fileType; } public void setFileType(String fileType) { this.fileType = fileType; } public String getFileURL() { return fileURL; } public void setFileURL(String fileURL) { this.fileURL = fileURL; } public String getId_() { return id_; } public void setId_(String id) { id_ = id; } }
