org.apache.poi.openxml4j.exceptions.OpenXML4JRunti

问题:

I'm facing org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Fail to save:an error occurs while saving the package : The part /docProps/app.xml fail to be saved in the stream with marshaller <br/> org.apache.poi.openxml4j.opc.internal.marshallers.DefaultMarshaller@7c81475b

Exception when try to write the each test scenario result(PASS or FAIL) into Excel sheet(.xlsx) after the each test scenario execution completion. I write the following two different modules for this purpose.

Please tell me where is the problem and how to resolve it..

//Method for writing results into Report
 public void putResultstoReport(String values[])
 {
      int j=NoofTimesExecuted;
      NoofTimesExecuted++;
      XSSFRow row = sheet.createRow(j);
      for(int i=0;i<values.length;i++)
      {
           XSSFCell cell = row.createCell(i);
           cell.setCellValue(values[i]);
      }
      try {
           System.out.println("Times:"+NoofTimesExecuted);
           wb.write(fileOut);
      }
      //fileOut.flush();
      //fileOut.close();
      }
      catch(Exception e) {
           System.out.println("Exception at closing opened Report :"+e);
      }

//Method for Creating the Excelt Report
 public void createReport()
 {
      String FileLocation = getProperty("WorkSpace")+"//SCH_Registration//OutPut//TestResults.xlsx";
      try {
           fileOut = new FileOutputStream(FileLocation);
           String sheetName = "TestResults"; //name of sheet
           wb = new XSSFWorkbook();
           sheet = wb.createSheet(sheetName);
           fileOut.flush();
           fileOut.close();
      }
      catch(Exception e)
      {
           System.out.println("Exception at Create Report file:"+e);
      }
}

回答1:

I also had this error.

I found my mistake was caused because I was opening the same file / workbook multiple times.

So I would recommend to make sure you are opening just once before attempting to close as well.

回答2:

I had this problem today and fixed it already.

The problem is in putResultstoReport()

You can't wb.write(fileOut); in your cycle.

resolution:

first call putResultstoReport(); then wb.write(fileOut);

I had similar Issue. Finally I got the reason and that was version for the below jar file was getting overrided.

  org.apache.xmlgraphics:batik-dom

Hence, I added below dependency and now it is working fine.

<dependency>
    <groupId>org.apache.xmlgraphics</groupId>
    <artifactId>batik-dom</artifactId>
    <version>1.8</version>
</dependency>

This jar contains dependency for xalan. To generate the report xalan is required.
