Please find the query description below: I submit the excel file from the client using IE Explorer 5.5 by the code given below:
<form action="http://xxx/POIExample" method="post" enctype="multipart/form- data"> <input size="70" type="file" name="spreadsheet" /> <input type="submit" value="Upload File" /> </form> In the servlet (running in Weblogic 6.1) I remove the extra data which comes in the HttpServletRequest and have the extract (only the content of the file) in the String "file": Then I use the following code to create the workbook //the parse method returns the content of the excel file which was uploaded 1. String file = parse(req.getInputStream(),req.getContentLength (),req.getContentType()); //this line creates the ByteArrayInputStream 2. ByteArrayInputStream is = new ByteArrayInputStream(file.getBytes()); //then try to create the workbook 3. HSSFWorkbook wb = new HSSFWorkbook(is); If i upload the excel file from the client which is less than 64.5 kb, the HSSFWorkbook gets created successfully and I am able to read data. But if the excel file size is greater than 64.5 kb it throws an exception java.io.IOException: block[ 63 ] already removed at org.apache.poi.poifs.storage.BlockListImpl.remove (BlockListImpl.java:133) at org.apache.poi.poifs.storage.BlockAllocationTableReader.fetchBlocks (BlockAllocationTableReader.java:227) at org.apache.poi.poifs.storage.BlockListImpl.fetchBlocks (BlockListImpl.java:165) at org.apache.poi.poifs.filesystem.POIFSFileSystem.processProperties (POIFSFileSystem.java:441) at org.apache.poi.poifs.filesystem.POIFSFileSystem.<init> (POIFSFileSystem.java:139) at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init> (HSSFWorkbook.java:175) at lehman.brokerlink.servlets.POIExample.doProcess(POIExample.java:88) at lehman.brokerlink.servlets.POIExample.doPost(POIExample.java:26) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at weblogic.servlet.internal.ServletStubImpl.invokeServlet (ServletStubImpl.java:265) at weblogic.servlet.internal.ServletStubImpl.invokeServlet (ServletStubImpl.java:200) at weblogic.servlet.internal.WebAppServletContext.invokeServlet (WebAppServletContext.java:2456) at weblogic.servlet.internal.ServletRequestImpl.execute (ServletRequestImpl.java:2039) at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:139) at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:120) Please do let me know why this kind of exception may be getting thrown and/or how to rectify this.
