[英]Export Crystal reports to PDF in java via cfml
使用 Commandbox 4.7.0+00026,我正在嘗試打開 Crystal Reports 文檔以准備 output 作為 PDF。 我無法打開文件,出現錯誤
java.lang.NoClassDefFoundError: com/crystaldecisions/reports/common/data/CrystalResultSet
在線的
var rd = rcd.open(reportPath, 0);
我已經確認 CrystalCommon2.jar 在 lib 文件夾中。
這是完整的 CommandBox 任務運行器:
component{
/*
The .jar files from Java Reporting Component SDK are copied to `box\engine\cfml\cli\cfml-web\lib`
*/
property name = "out" inject = "java:java.io.ByteArrayOutputStream";
property name = "crs" inject = "java:com.crystaldecisions.reports.common.data.CrystalResultSet";
property name = "crv" inject = "java:com.crystaldecisions.report.web.viewer.CrystalReportViewer";
property name = "oro" inject = "java:com.crystaldecisions.sdk.occa.report.application.OpenReportOptions";
property name = "rcd" inject = "java:com.crystaldecisions.sdk.occa.report.application.ReportClientDocument";
property name = "ref" inject = "java:com.crystaldecisions.sdk.occa.report.exportoptions.ReportExportFormat";

*/
function run(){
var reportPath = "c:\reports\Statement of Account.rpt";
var openAsReadOnly = oro._openAsReadOnly;
var inprocConnectionString = rcd.inprocConnectionString;
var rd = rcd.open(reportPath, 0);
out.reset();
}
}
一些資源表明存在 CRConfig.xml 需求,但我沒有成功 - 嘗試了無數個位置。 CRConfig.xml:
<?xml version="1.0" encoding="utf-8"?>
<CrystalReportEngine-configuration>
<reportlocation>..</reportlocation>
<timeout>0</timeout>
<ExternalFunctionLibraryClassNames>
<classname></classname>
</ExternalFunctionLibraryClassNames>
</CrystalReportEngine-configuration>
其他資源維護 CrystalReportsEngine-config.xml 必須存在。 同樣,不確定它應該放在哪里。
<?xml version="1.0" encoding="utf-8"?>
<CrystalReportEngine-configuration>
<reportlocation>c:\reports\</reportlocation>
<timeout>10</timeout>
<keycode>MyLicenseKeyCodeHere</keycode>
</CrystalReportEngine-configuration>
原來我將 Crystal Reports jar 文件放到了錯誤的文件夾中。
將它們放入此 function 返回的同一文件夾中:
function jarPath(){
variables.jarPath = createObject( "java", "java.io.File" ).init(
createObject( "java", "runwar.LaunchUtil" )
.getClass()
.getProtectionDomain()
.getCodeSource()
.getLocation()
.toURI()
.getSchemeSpecificPart() )
.getAbsolutePath();
job.start(serialize(variables.jarPath));
job.complete();
}
