org.apache.poi.openxml4j.exceptions.InvalidFormatException: Can't read content types part !

Hi Team,

I am trying ti read the .xlsx  file from eclipse using the maven project.

Here all the dependencies I am using

<dependency>

<groupId>org.apache.poi</groupId>

<artifactId>poi</artifactId>

<version>3.9</version>

</dependency>

<dependency>

<groupId>org.apache.poi</groupId>

<artifactId>poi-ooxml</artifactId>

<version>3.9</version>

</dependency>

<dependency>

<groupId>dom4j</groupId>

<artifactId>dom4j</artifactId>

<version>1.6.1</version>

</dependency>

<dependency>

<groupId>org.apache.xmlbeans</groupId>

<artifactId>xmlbeans</artifactId>

<version>2.3.0</version>

</dependency>

<dependency>

<groupId>org.apache.poi</groupId>

<artifactId>poi-ooxml-schemas</artifactId>

<version>3.9</version>

</dependency>

code for reading the excel file

Workbook workBook = WorkbookFactory.create(new File(SourceFile));

            Sheet metadataSheet = workBook.getSheet(SheetName);

Its returning the exception. "org.apache.poi.openxml4j.exceptions.InvalidFormatException: Can't read content types part !"

I have tried by using this code as well

XSSFWorkbook workbook = new XSSFWorkbook(excelFile);

XSSFSheet metadataSheet = workbook.getSheet(SheetName)

it is returning this exception " org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Uncaught Throwable

java.lang.NullPointerException: in is null"

Please guide me or advice how to resolve this.

I have tried using the jxl java API , I am able to read the .xls but not able to read .xlsx by using this.

Thanks In Advance
