try to change the import of Sheet class with
org.apache.poi.ss.usermodel.Sheet
what you use right now is Sheet for Powerpoint Document.
here the reference of the library you use right now:

java.lang.NoClassDefFoundError: com/sun/star/lang/XEventListener

I am using pdfbox(pdfbox-app-2.0.0-RC3.jar) to convert any file to .pdf file. I am also using jodconverter-2.2.1.jar library.
Code I wrote (following this):
import com.artofsolving.jodconverter.openoffice.connection.*;
import com.artofsolving.jodconverter.openoffice.converter.*;
import com.artofsolving.jodconverter.*;
import java.io.File;
public class PdfBox {
public static void main(String[] args) throws Exception{
try {
OpenOfficeConnection con=new SocketOpenOfficeConnection(8100);
con.connect();
File inputFile=new File("x.docx");
File outputFile=new File("x.pdf");
DocumentConverter converter=new OpenOfficeDocumentConverter(con);
converter.convert(inputFile,outputFile);
con.disconnect();
} catch (Exception e) {
System.out.println(e);
}
}
}
Error message I get:
Any idea to get rid of this will be appreciated.

You need to add openoffice-ridl-2.0.3.jar (or some version of openoffice's jar) to your classpath.

NullpointerException when trying to read XLSX file

I currently have this code to open an xlsx file using apache POI
File existingXlsx = new File("/app/app.xlsx");
System.out.println("File Exists: " + existingXlsx.exists());
Workbook workbook = WorkbookFactory.create(existingXlsx);
When I try to execute this, I get the following output
File Exists: true
java.lang.NullPointerException
at org.apache.poi.xssf.usermodel.XSSFWorkbook.onDocumentRead(XSSFWorkbook.java:270)
at org.apache.poi.POIXMLDocument.load(POIXMLDocument.java:159)
at org.apache.poi.xssf.usermodel.XSSFWorkbook.<init>(XSSFWorkbook.java:186)
at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:91)
The file I am trying to open can be opened in Excel and show the data correctly, what can I do to get POI to read the XLSX file?
Here is the file that breaks;
https://mega.co.nz/#!FJMWjQKI!CzihQgMVpxOQDTXzSnb3UFYSKbx4yFTb03-LI3iLmkE
Edit
I have also tried, this results in the same error;
Workbook workbook = new XSSFWorkbook(new FileInputStream(existingXlsx));
Edit
I found the line it is throwing the exception on;
WorkbookDocument doc = WorkbookDocument.Factory.parse(getPackagePart().getInputStream());
this.workbook = doc.getWorkbook();
Map<String, XSSFSheet> shIdMap = new HashMap<String, XSSFSheet>();
for(POIXMLDocumentPart p : getRelations())
{
if(p instanceof SharedStringsTable) sharedStringSource = (SharedStringsTable)p;
else if(p instanceof StylesTable) stylesSource = (StylesTable)p;
else if(p instanceof ThemesTable) theme = (ThemesTable)p;
else if(p instanceof CalculationChain) calcChain = (CalculationChain)p;
else if(p instanceof MapInfo) mapInfo = (MapInfo)p;
else if (p instanceof XSSFSheet) {
shIdMap.put(p.getPackageRelationship().getId(), (XSSFSheet)p);
}
}
stylesSource.setTheme(theme); <== BREAKS HERE
Edit
After some research POI seems to be unable to find the styles.xml and the workbook.xml, I find this strange because a simple reader like TextWrangler which shows the structure of the archive shows me the styles xml.
How do I fix this? Is there a default styles.xml and workbook.xml which I can insert into the archive?

Now I've dowloaded the latest packages:
poi-src-3.9-20121203.zip (As source)
xmlbeans-2.6.0.zip
jsr173_1.0_api.jar
resolver.jar
xbean.jar
xbean_xpath.jar
xmlbeans-qname.jar
xmlpublic.jar
ooxml-schemas-1.1.jar
dom4j-1.6.1.jar
commons-codec-1.8.jar
commons-logging-1.1.3.jar
ant.jar (ant 1.7)
And your test2.xlsx were read without problems:
public static void main(String arg []){
try {
//File existingXlsx = new File("/app/app.xlsx");
File existingXlsx = new File("c:/Java/poi-3.9/test-data/__theproblem/test2.xlsx");
System.out.println("File Exists: " + existingXlsx.exists());
Workbook workbook = WorkbookFactory.create(existingXlsx);
} catch (Exception e) {
e.printStackTrace();
}
}
Are you sure you're using ooxml-schemas-1.1.jar as the POI documentation recommends?
EDIT
Hmm. It's work for me from jar too.
I have downloaded poi-bin-3.9-20121203.tar.gz from
http://poi.apache.org/download.html
Made a new project in Eclipse, extracted all the jars from the zip:
lib/commons-codec-1.5.jar
lib/commons-logging-1.1.jar
lib/dom4j-1.6.1.jar
lib/junit-3.8.1.jar
lib/log4j-1.2.13.jar
lib/poi-3.9-20121203.jar
lib/poi-examples-3.9-20121203.jar
lib/poi-excelant-3.9-20121203.jar
lib/poi-ooxml-3.9-20121203.jar
lib/poi-ooxml-schemas-3.9-20121203.jar
lib/poi-scratchpad-3.9-20121203.jar
lib/stax-api-1.0.1.jar
lib/xmlbeans-2.3.0.jar
Add the test xlsx:
test-data/test2.xlsx
The test Java:
src/XlsxReadTest1.java
Source:
import java.io.File;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
public class XlsxReadTest1 {
public static void main(String arg []){
try {
File existingXlsx = new File("c:/Java/__Work/apache_POI/poi-3.9-bin/test-data/test2.xlsx");
System.out.println("File Exists: " + existingXlsx.exists());
Workbook workbook = WorkbookFactory.create(existingXlsx);
System.out.println("A1: " + workbook.getSheetAt(0).getRow(0).getCell(0).getStringCellValue());
} catch (Exception e) {
e.printStackTrace();
}
}
}
Run. (Tried with jdk1.7.0_07, jdk1.6.0_31)
Result:
File Exists: true
A1: Testing Edit
"Testing Edit" is the content of the first cell on the first sheet of your file.
I think, You may try this, from scratch.
(Maybe you are using other jars for your project, whom interfere with this jars in the class loader? Class loader is a cunning guy...)

I guess you just used the wrong poi package.
Try to download the following or you check the newest version from the page.
The following I tested in my Eclipse development:
http://www.apache.org/dyn/closer.cgi/poi/release/bin/poi-bin-3.9-20121203.zip
extract it, and include all the jars into your eclipse lib
I combine user1234's answer and my own approach, both are working on your test2.xlsx

import java.io.FileInputStream;

import org.apache.xmlbeans.XmlException;
public class Main {
/**

*/
public static void main(String[] args) {
// File existingXlsx = new File("app.xlsx");
File file = new File("test2.xlsx");
FileInputStream fs;
try {
fs = new FileInputStream(file);
OPCPackage xlsx = OPCPackage.open(fs);
XSSFExcelExtractor xe = new XSSFExcelExtractor(xlsx);
System.out.println(xe.getText());
} catch (FileNotFoundException e1) {
e1.printStackTrace();
} catch (XmlException e) {
e.printStackTrace();
} catch (OpenXML4JException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
/// -------------- Another approach
File existingXlsx = new File("test2.xlsx");
System.out.println("File Exists: " + existingXlsx.exists());
try {
Workbook workbook = new XSSFWorkbook(new FileInputStream(
existingXlsx));
Sheet worksheet = workbook.getSheet("Filter criteria");
Row row1 = worksheet.getRow(0);
Cell cellA1 = row1.getCell((short) 0);
String a1Val = cellA1.getStringCellValue();
System.out.println("A1: " + a1Val);
} catch (IOException e) {
e.printStackTrace();
}
}
}
finally I got the result:

If you want to read .xlsx, could you please try this code (uses apache poi 3.9) :
File file = new File("/app/app.xlsx");
FileInputStream fs = new FileInputStream(file);
OPCPackage xlsx = OPCPackage.open(fs);
XSSFExcelExtractor xe = new XSSFExcelExtractor(xlsx);
System.out.println(xe.getText());
The above code should display the content of the file app.xlsx.

Open excel sheet from JButton - Java Swing

I'm designing a form using swing.If report button was clicked in my form it have to open the predefined format excel sheet from my D drive.What code have to write in button action listener ??
Thanks ..

I'd recommend looking at the Desktop class in awt. There's a method here that should help you.
import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class OpenFile {
public static void main(String[] args) {
File file = new File("c:\\appNominalJournalFix.txt");
try {
Desktop.getDesktop().open(file);
} catch (IOException e) {
e.printStackTrace();
}
}
}

You can use Runtime class to open the excel using the default program in Windows
String filePath = "D:\\test.xls";
Process p =
Runtime.getRuntime()
.exec("rundll32 url.dll,FileProtocolHandler " + filePath);
You can also use Desktop API as below.
String filePath = "D:\\test.xls";
Desktop dt = Desktop.getDesktop();
dt.open(new File(filePath));

How to render PNG image from DFX file by using kabeja package?

I'm new to this kabeja package so please can some one provide code example or reading material to render PNG from DXF file using Java?

This is the sample code that generate PNG image from DXF file.
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.HashMap;
import org.kabeja.dxf.DXFDocument;
import org.kabeja.parser.*;
import org.kabeja.parser.ParserBuilder;
import org.kabeja.svg.SVGGenerator;
import org.kabeja.xml.*;
public class MyClass {
public static void main(String[] args) {
MyClas x=new MyClas();
x.parseFile("C:\\Users\\Space\\Desktop\\test2.dxf");
}
public void parseFile(String sourceFile) {
try {
FileOutputStream o=new FileOutputStream("C:\\Users\\Space\\Desktop\\test2.png");
InputStream in = new FileInputStream(sourceFile);//your stream from upload or somewhere
Parser dxfParser = ParserBuilder.createDefaultParser();
dxfParser.parse(in, "");
DXFDocument doc = dxfParser.getDocument();
SVGGenerator generator = new SVGGenerator();
//org.xml.sax.InputSource out = SAXPNGSerializer;
SAXSerializer out = new org.kabeja.batik.tools.SAXPNGSerializer();
out.setOutput(o);
generator.generate(doc,out,new HashMap());
} catch (ParseException e) {
e.printStackTrace();
} catch (Exception ioe) {
ioe.printStackTrace();
}
}
}
Hope you get what you required :)
