Unable to generate Chinese PDF from Excel using Aspose Cell in Multi-Threaded environment(Weblogic 10.3)

dhinesh · January 19, 2012, 8:19am

Hi,

We are using Excel Templates in our java code which we load using Aspose cells (2.4.2.4) and generate PDF using the Workbook.save(outputStream,FileFormatType.PDF);<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

We are loading multiple language excel templates namely, English and Simplified Chinese Language(PMingLiU.ttf font) in the Workbook object and we generate individual languages PDF respectively.

We are experiencing problem when we run parallel threads to generate Chinese PDF. The problem does not happen when only 1 thread is used to generate PDF.

Note: Please provide solution as soon as possible, have attached the sample program which we used to reproduce the issue, assume the Excel files which we used are

ELN001-X0509_SICHN - Chinese Excel Template (Has Simplified Chinese Text)

ELN001-X0509_ENG - English Excel Template (Has English Text)

Issue 1:

The Chinese PDF which gets generated is not having all the Chinese Text available.

Also in certain cases it shows the font error - < cannot extract the embedded font 'FAAABE_PMingLiU'. Some characters may not display or print correctly> while open the pdf. Please find attached output pdf.

Issue 2 :

Also in certain cases it throws Out of memory exception. Please find below exception details.

Thanks a lot.
Text formatting issue is resolved but shapes are not rendered properly.
Suppose if i have a line shape in excel template, the width of the line is reduced in pdf.

Please attach the sample input Excel file and output PDF file (generated by the latest fixed version v7.1.0.3), also give us screen shot to highlight (encircle with red color) the problematic area on the shape to make us better understand the problem, we will look into it soon.

Thank you.

dhinesh · January 31, 2012, 6:39am

Please find the attached template and generated pdf

amjad.sahi · January 31, 2012, 7:14am

Hi,

Yes, you are right. I tested with your file and found the issue in the PDF file, i.e. the bottom border line of the image shape (above) in the second and third worksheets is not rendered fine. I have reopened the issue and we will soon look into it.

Thank you.

shakeel.faiz · February 3, 2012, 4:00am

Hi,

We have fixed this issue. Please download: Aspose.Cells for Java v7.1.0.4

dhinesh · February 6, 2012, 4:28am

Hi,

Currently we are using aspose-cells-2.4.2.4.jar file. For all the above stated issues we can use the latest version you gave us going forward. But currently we need the issues to be fixed in aspose-cells-2.4.2.4.jar file. Can you provide us ? i mean in the same jar file can you update all the changes and give us the same version jar file ?

shakeel.faiz · February 6, 2012, 4:37am

Hi,

We do not fix issues based on older versions. It is our policy to fix the issues based on latest version.

dhinesh · February 10, 2012, 3:23am

Hi,

Is there any API link for aspose-cells-7.1.0.4.jar
am not able to do the below opertaion.

Blob excelBlob = (Blob)exlXmlBlob[1];

this.excelWb= new Workbook(excelBlob.getBinaryStream());

Worksheet sheet = excelWb.getWorksheets().get(iSheetNumber);

it says runtime error, constructor not available for Workbook

and method not found error for excelWb.getWorksheets().

shakeel.faiz · February 10, 2012, 3:44am

Hi,
