JasperReport Error evaluating expression: Source text : new java.lang.Integer(1)
提问by kripton haz
I'm using JasperSoft Studio 5.1.0 for creating my report. This is library I used so far
我正在使用 JasperSoft Studio 5.1.0 创建我的报告。这是我到目前为止使用的库
- commons-beanutils-1.8.3.jar commons-collections.jar commons-digester-1.7.jar commons-javaflow-20060411.jar commons-logging-1.1.3.jar groovy-all-1.7.5.jar itext-2.1.7.jar jasperreports-5.1.0.jar
- commons-beanutils-1.8.3.jar commons-collections.jar commons-digester-1.7.jar commons-javaflow-20060411.jar commons-logging-1.1.3.jar groovy-all-1.7.5.jar itext-2.1。 7.jar jasperreports-5.1.0.jar
I'm trying using parameter and it's not showing any error when I see the preview on JasperSoft Studio, but when I try to print from my Java program it's show an error like this:
我正在尝试使用参数，当我在 JasperSoft Studio 上看到预览时它没有显示任何错误，但是当我尝试从我的 Java 程序打印时它显示如下错误：
net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : Source text : new java.lang.Integer(1)
net.sf.jasperreports.engine.fill.JRExpressionEvalException：评估表达式时出错：源文本：new java.lang.Integer(1)
the code I use on my program for action performed is like this
我在我的程序中用于执行操作的代码是这样的
try
{
String NamaFile = "src/Laporan Penawaran.jasper";
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection konek = Koneksi.getKoneksi();
HashMap hash = new HashMap();
hash.put("param1",no_tender.getText());
File file = new File(NamaFile);
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(file.getPath());
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, hash,konek);
JasperViewer.viewReport(jasperPrint);
} catch(Exception ex) {
System.out.println(ex);
}
I just wondering maybe my jasper file is error, but when I try to erase all field and using only static text the error still exist. What am I supposed to do?
我只是想知道我的 jasper 文件可能是错误的，但是当我尝试擦除所有字段并仅使用静态文本时，错误仍然存在。我应该做些什么？

well I'm just trying to update groovy-all to version 2. And after that there's no problem at all and work smoothly :)
好吧，我只是想将 groovy-all 更新到版本 2。之后就完全没有问题并且工作顺利了:)
note: make sure you are using a specific version for each library, somehow the new one it's not always match for your report
注意：确保您为每个库使用特定版本，不知何故新版本并不总是与您的报告匹配

FIX Worked for me
FIX 为我工作
- I have updated all reports/subreports language property from
"groovy"to"Java"and it's fixed . - Though it looks like workaround I suggest to update library which will include the missing class in
jasperreports-5.1.2.jar.
- 我已将所有报告/子报告语言属性从
"groovy"to更新为已"Java"修复。 - 虽然看起来像解决方法，但我建议更新库，其中将包含
jasperreports-5.1.2.jar.
