Jasper with php帮助将从ireport/modules/ext复制的所有jar文件放在何处

我是贾斯佩雷波特的新手

有人能帮我从ireport/modules/ext复制jar文件吗

只有ireport/modules/ext中的jar文件就足够了吗

如何与php连接 有人能帮我吗

谁能帮我把jar文件复制到哪里 ireport/modules/ext？将仅在ir中保存jar文件

您必须将其复制到java_主目录。我正在使用windows7，所以在我的例子中它将是C:\Program Files\Java\jre7\lib\ext。请确保您已经为Java\u主页设置了类路径。（我希望你知道怎么做）

只有ireport/modules/ext中的jar文件就足够了吗

是的，这对您很有帮助

如何与php连接 浏览下面给出的例子

 include('../includes/javabridge.php');
java_set_file_encoding("UTF-8");

// Load the Jasper Report

$jrxml = new java("net.sf.jasperreports.engine.xml.JRXmlLoader");
$jasperTemplate = $jrxml->load(realpath("customer.jrxml"));

// Load the Query 

$_Query = new java("net.sf.jasperreports.engine.design.JRDesignQuery");
$_Query->setText("select * FROM customers");
$jasperTemplate->setQuery($_Query);

// Compile the Report after including the Query

$compile = new JavaClass("net.sf.jasperreports.engine.JasperCompileManager");
$report = $compile->compileReport($jasperTemplate);

// Connect to the database

$class = new JavaClass("java.lang.Class");
$class->forName("com.mysql.jdbc.Driver");
$mysqlDriver = new JavaClass("java.sql.DriverManager");
$conn = $mysqlDriver->getConnection("jdbc:mysql://localhost:3309/dbcustomer?user=root&password=");

// Now Fill the Report 
$jasperFill = new JavaClass("net.sf.jasperreports.engine.JasperFillManager");
$params = new Java("java.util.HashMap");
$params->put("title", "Customer");
$jasperPrint = $jasperFill->fillReport($report, $params, $conn);

// Now Export the Report to desired format 

$jasperExport = new java("net.sf.jasperreports.engine.JRExporter");

    // Change here to generate report in pdf , excel,docx etc..

这对我帮助很大。你为什么不纠正一下他的英语，而关闭这个问题？
