　　Compiere自带的报表，在导出为pdf文档时，会在pdf文档的背景上附带有Demo Version字样，下面讲述如何移除Demo Version字样。

 

1，把jPDFPrinter.jar放到compiere_all（源码）的lib文件夹。

 

2，在compiere_all/print/src/org/compiere/print 建立一个print.java类。

// add by huhailong 20071109

package org.compiere.print;

 

import java.io.*;

import java.awt.*;

import java.awt.print.*;

import javax.print.*;

import javax.print.attribute.*;

 

import org.compiere.print.layout.*;

 

publicclass Print implements Pageable, Printable, Doc

{

   

    public Print (LayoutEngine layout, boolean isCopy)

    {

       m_layout = layout;

       m_isCopy = isCopy;  

    }

   

    private LayoutEngine m_layout; 

    privateboolean          m_isCopy;

   

    publicint getNumberOfPages()

    {

       returnm_layout.getNumberOfPages();

    }

   

    privateboolean havePage (int pageIndex)

    {

       if (pageIndex < 0 || pageIndex >= m_layout.getNumberOfPages())

           returnfalse;

       returntrue;

    }

   

    public PageFormat getPageFormat (int pageIndex) throws IndexOutOfBoundsException

    {

       if (!havePage(pageIndex))

           thrownew IndexOutOfBoundsException("Print.getPageFormat - no page index" + pageIndex);

       returnm_layout.getPageFormat();

    }

   

    public Printable getPrintable (int pageIndex) throws IndexOutOfBoundsException

    {

       if (!havePage(pageIndex))

           thrownew IndexOutOfBoundsException("Print.getPrintable - no page index " + pageIndex);

       returnthis;

    }

   

    publicint print (Graphics graphics, PageFormat pageFormat, int pageIndex)

       throws PrinterException

    {

       if (!havePage(pageIndex))

           return Printable.NO_SUCH_PAGE;    

       Rectangle r = new Rectangle (0, 0, (int)m_layout.getPaper().getWidth(true),

              (int)m_layout.getPaper().getHeight(true));

       Page page = m_layout.getPage(pageIndex+1);

       // 

       page.paint((Graphics2D)graphics, r, false, m_isCopy);

       m_layout.getHeaderFooter().paint((Graphics2D)graphics, r, false);    

       return Printable.PAGE_EXISTS;

    }

   

    public DocFlavor getDocFlavor()

    {

       return DocFlavor.SERVICE_FORMATTED.PAGEABLE;

    }

   

    public Object getPrintData() throws IOException

    {

       returnthis;

    }

   

    public DocAttributeSet getAttributes()

    {

       returnnull;

    }

   

    public Reader getReaderForText() throws IOException

    {

       returnnull;

    }

   

    public InputStream getStreamForBytes() throws IOException

    {

       returnnull;

    }

}   // Print

 

3，把ReportEngine.java的 createPDF (File file) 方法改为以下內容。

/**startaddbyhuhailong20071109*/

import com.qoppa.pdfPrinter.PDFPrinterJob;

/**endaddbyhuhailong20071109*/

 

publicboolean createPDF (File file)

    {

       String fileName = null;

       URI uri = null;

 

       try

       {

           if (file == null)

              file = File.createTempFile ("ReportEngine", ".pdf");

           fileName = file.getAbsolutePath();

           uri = file.toURI();

           if (file.exists())

              file.delete();

 

       }

       catch (Exception e)

       {

           log.log(Level.SEVERE, "file", e);

           returnfalse;

       }

          

       log.fine(uri.toString());

      

       /**startaddbyhuhailong20071109*/

       if (m_layout == null)

           layout ();

       Print print = new Print (m_layout, false);

       PrintRequestAttributeSet prats = m_layout.getPaper().getPrintRequestAttributeSet ();

       prats.add (new JobName(fileName, Locale.getDefault()));    

       prats.add (new Destination (uri));    

       try

       {

           if (false)

              Class.forName("com.qoppa.pdfPrinter.PDFPrinterJob");       

           com.qoppa.pdfPrinter.PDFPrinterJob job = (PDFPrinterJob)PDFPrinterJob.getPrinterJob ();   

           job.setPrintable(print, m_layout.getPageFormat());

           job.print(fileName);

       }

       catch (ClassNotFoundException cnf)

       {         

           returnfalse;

       }

       catch (Exception e)

       {         

           returnfalse;

       }

       /**endaddbyhuhailong20071109*/

 

       /**startcommentbyhuhailong20071109*/

       /*try

       {

           if (m_layout == null)

              layout ();

           ArchiveEngine.get().archive(m_layout, m_info);

           Document.getPDFAsFile(fileName, m_layout.getPageable(false));

       }

       catch (Exception e)

        {

           log.log(Level.SEVERE, "PDF", e);

           return false;

       }*/

       /**endcommentbyhuhailong20071109*/

 

       File file2 = new File(fileName);

       log.info(file2.getAbsolutePath() + " - " + file2.length());

       return file2.exists();

    }   // createPDF

 

4，修改 compiere_all/print/build.xml，如下：

<pathelement path="../lib/jPDF.jar"/>

       <!-- start add by huhailong 20071109 -->

       <pathelement path="../lib/jPDFPrinter.jar"/>

       <!-- end add by huhailong 20071109 -->

把jPDFPrinter.jar抄到 compiere_all/print/

 

5，修改 compiere_all/Client/build.xml，如下：

<pathelement path="../tools/lib/j2ee.jar"/>

       <!-- start add by huhailong 20071109 -->

       <pathelement path="../lib/jPDFPrinter.jar"/>

       <!-- end add by huhailong 20071109 -->

……

<unjar src="../interfaces/Interfaces.jar" dest="${build.dir}" />

    <!-- start add by huhailong 20071109 -->

       <unjar src="../lib/jPDFPrinter.jar" dest="${build.dir}" />

       <!-- end add by huhailong 20071109 -->

 

6，编译print，然后编译client，测试，移除Demo Version成功。
