                                                                           关键字  php java bridge iReport jasperReports pdf

1.先安装配置环境，请参阅前辈们的文章 我也提供一个参考地址 http://zhengdl126.iteye.com/blog/418574  按文中第一种配置就ok了。



2.编辑数据库连接的java通用类JdbcConnection.java

/*

* @(#)JdbcConnection.java

*

* Copyright (c) 2010 AsiaSoft Company Limited. All Rights Reserved.

*/



package org.altic.jasperReports;



import java.io.InputStream;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

import java.util.Properties;



/**

* Class description goes here.

*

* @version 1.00 2010-3-12

* @author Frank.wu

*/

public class JdbcConnection {



private String driver; // "oracle.jdbc.driver.OracleDriver";

private String connectString; // "jdbc:oracle:thin:@YOUR_ORACLE_HOST:1521:YOUR_SID";

private String user; // "YOUR_ORACLE_USER_NAME";

private String password; // "YOUR_ORACLE_PASSWORD";



public JdbcConnection() {

// loadPropertiesConnection();

}



public JdbcConnection(String driver, String connectString, String user,

String password) {

this.driver = driver;

this.connectString = connectString;

this.user = user;

this.password = password;

}



public void loadPropertiesConnection() {



this.driver = "";

this.connectString = "";

this.user = "";

this.password = "";



try {

Properties props = new Properties();

InputStream resourceAsStream = getClass().getResourceAsStream(

"/connection.properties");

props.load(resourceAsStream);

this.setDriver(props.getProperty("driver"));

this.setConnectString(props.getProperty("connectString"));

this.setUser(props.getProperty("user"));

this.setPassword(props.getProperty("password"));

} catch (Exception e) {

e.printStackTrace();

}

}



public Connection getConnection() {

try {

// Change these settings according to your local configuration

Class.forName(this.getDriver());

Connection conn = DriverManager.getConnection(this

.getConnectString(), this.getUser(), this.getPassword());

return conn;

} catch (ClassNotFoundException e) {

e.printStackTrace();

} catch (SQLException e) {

e.printStackTrace();

}

return null;

}



public String toString() {

return " Driver : " + this.getDriver() + " | " + " ConnectString : "

+ this.getConnectString() + " | " + " User : " + this.getUser()

+ " | " + " Password : " + this.getPassword();

}



public String getConnectString() {

return connectString;

}



public void setConnectString(String connectString) {

this.connectString = connectString;

}



public String getDriver() {

return driver;

}



public void setDriver(String driver) {

this.driver = driver;

}



public String getPassword() {

return password;

}



public void setPassword(String password) {

this.password = password;

}



public String getUser() {

return user;

}



public void setUser(String user) {

this.user = user;

}

}

3.在Eclipse下面，将项目已导出jar包的形式导出，（方法是选择项目，右键-->export，然后next就可以了），在这里我的导出为iReport1.jar

4.将项目中相应的jar包都复制到 D:\lib文件夹下。在文章的末尾可以下载到。

5.iReport.php代码

setDriver("com.mysql.jdbc.Driver");

// url for mysql

$Conn->setConnectString("jdbc:mysql://localhost/aerp");

// mysql user name

$Conn->setUser("root");

// mysql password

$Conn->setPassword("root");

  

   $jrm = new JavaClass("net.sf.jasperreports.engine.JasperRunManager");

   $jrm->runReportToPdfFile(

   "D:/report1.jasper",

   "D:/report5.pdf",

   new Java("java.util.HashMap"),

   $Conn->getConnection()

   );

    } catch (JavaException $ex) {

    $trace = new Java("java.io.ByteArrayOutputStream");

$ex->printStackTrace(new Java("java.io.PrintStream", $trace));

print "java stack trace: $trace\n";

}

?>

6.启动apache....

7.http://localhost/demo/iReport.php  即可，在D:/下就可以看到生成了一个pdf报表。


我也是这几天反复尝试再弄出来，各位如果不理解之处，可以联系本人。[e-mail]
