在这篇文章中，我们将带领您了解JasperReports API：调用JasperCompileManager.compileReport的全貌，包括String方法引发了MalformedByteSequenceException异常的相关情况。同时，我们还将为您介绍有关.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列、asp.net – NullReferenceException在PipelineStepManager.ResumeSteps中、Caused by: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列、com.google.appengine.api.datastore.PreparedQuery.TooManyResultsException的实例源码的知识，以帮助您更好地理解这个主题。

JasperReports API：调用JasperCompileManager.compileReport（String）方法引发了MalformedByteSequenceException异常
public void openReport() { try { HashMap params = new HashMap(); params.put("aapor", 19); JasperReport jasperReport1 = JasperCompileManager.compileReport("C:/Users/emidemi.emidemi-PC/Documents/NetBeansProjects/FleetManager/src/FleetManager/newReport5.jasper"); JasperPrint jasperPrint1 = JasperFillManager.fillReport(jasperReport1, params, conn.getConn()); JRViewer viewer = new JRViewer(jasperPrint1); } catch (Exception e) { System.out.println(e.getMessage()); }}以上是我的脚本。
这是我的错误：
com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.BUILD SUCCESSFUL (total time: 7 seconds)有谁知道这是为什么发生以及如何解决？
答案1
小编典典字符编码存在问题。您是否尝试过在报告开头更改编码行？
例如，对于中欧字母，请更改：
<?xml version="1.0" encoding="UTF-8"?>通过
<?xml version="1.0" encoding="CP1250"?>您在这里有不同字符编码标准的列表：http

希望能奏效
.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列
Caused by: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列
解决方案：
把出现问题 xml 文件中的 UTF-8 修改为 UTF8 即可且看如下：
asp.net – NullReferenceException在PipelineStepManager.ResumeSteps中
由于我将主机更改为ASP.NET 4.0 Web窗体和IIS7集成模式,我的网站通常会出现以下错误：
[NullReferenceException: Object reference not set to an instance of an
object.] System.Web.PipelinestepManager.ResumeSteps(Exception
error) +197
System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext
context,AsyncCallback cb) +89
System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest
wr,HttpContext context) +189
但是,网站工作正常.如何解决这个问题？
解决方法
正如Gisli Konrao发表的,在评论中,这是因为您有一个自定义事件处理程序连接在ASP.NET MVC 4应用程序中.
在我的情况下,我有：
this.BeginRequest += new EventHandler(MvcApplication_BeginRequest);
在注释掉这个语句之后,问题就被修复了(ASP.NET将这些事件放在后台,所以只是定义它会使它工作).
