java在ApacheTomcat上部署GWT应用程序
在服务器端,我有一个用于将SVG文件转换为PDF的类
public class PdfHandler {
private File savedFile;
private File svgTempFile;
public PdfHandler(String fileName) {
this.savedFile = new File(File.separator + "documents" + File.separator + fileName);
}
public void convertToPdf(String inputFileName) {
this.svgTempFile = new File(inputFileName);
System.out.println(inputFileName);
if (this.svgTempFile.exists()){
System.out.println("Svg File exists");
}
else {
System.out.println("Svg File not exists");
}
try {
Transcoder transcoder = new PDFTranscoder();
System.out.println("Transcoder created");
FileInputStream fis = new FileInputStream(this.svgTempFile);
System.out.println("Input stream created");
FileOutputStream fos = new FileOutputStream(this.savedFile);
System.out.println("Output stream created");
TranscoderInput transcoderInput = new TranscoderInput(fis);
System.out.println("Transcoder input created");
TranscoderOutput transcoderOutput = new TranscoderOutput(fos);
System.out.println("Transcoder output created");
transcoder.transcode(transcoderInput, transcoderOutput);
System.out.println("Conversion finished");
fis.close();
fos.close();
} catch (Exception ex) {
ex.printStackTrace();
System.out.println("Exception");
} finally {
this.svgTempFile.delete();
System.out.println("File deleted");
}
System.out.println("End of method");
}
}
我有一个RPC调用的方法
public String generatePdf(PayDoc filledDoc) {
//String svgFileName = this.generateSvg(filledDoc);
//String pdfFileName = this.generateFileName("pdf");
PdfHandler pdfHandler = new PdfHandler("myPdf.pdf");
pdfHandler.convertToPdf(File.separator + "documents" + File.separator + "mySvg.svg");
return null;//pdfFileName;
}
在eclipse中,所有这些都可以正常工作,但在Tomcat上不行。当我在Tomcat上调用它时,RPC失败 这是Tomcat控制台输出:
\documents\mySvg.svg
Svg File exists
Transcoder created
Input stream created
Output stream created
Transcoder input created
Transcoder output created
File deleted
在“文档”文件夹中,我有“mySvg.svg”(仍然没有删除)和“myPdf.pdf”(它是空的)

看起来您没有在部署的应用程序中包含所需的库
ElementTraversal
是xml-apis-X.XX.X.jar
的一部分,必须与应用程序捆绑在一起由于有大量的构建工具,我不知道您使用的是哪一种,所以我不能建议更改
