Re: Out of Memory problem
I tried to increase memory of JVM through Tomcat - but not much change. I believe the way i am using my procedure (creating objects) that might be wrong.
Below is some statistics (logger is displaying) when i am trying to render the PDF with 1 page / 2 pages / 3 pages etc
1 page report 2 pages report 3 pages report
Initial Heap size ~ 12M 14M 10M
Current Heap size ~ 64M 10M 9M
Total memory used~ 52M 4M -1M
If i try for 4 pages report then i get OutOfMemory Error. Once i get this error then even sometimes iget errors for 2 pages / 3pages report too. Total memory used always go in -ve later.
I am attaching my procedure below which i use to render the pdf
--
//Following method is used to render PDFpublic synchronized void renderPDF (...) throws Exception { ... get xsl file path
get xml
org.apache.fop.image.FopImageFactory.resetCache(); //get the user config file for pdf Arial unicode font File userConfigFile = new File(cnffilepath); Options options = new org.apache.fop.apps.Options(userConfigFile);
TraxInputHandler xsltinput = new TraxInputHandler(new File(xmlpath), new File(xslpath));ByteArrayOutputStream outputPDFBuffer = new ByteArrayOutputStream();Driver driver = new Driver(); driver.setLogger(new org.apache.avalon.framework.logger.Log4JLogger(logger) );driver.setRenderer(Driver.RENDER_PDF);driver.setOutputStream(outputPDFBuffer);xsltinput.run(driver);FileOutputStream pdfDoc = new FileOutputStream(pdfpath);pdfDoc.write(outputPDFBuffer.toByteArray(), 0, outputPDFBuffer.size());pdfDoc.flush();pdfDoc.close();}//renderPDF-

You will need to find it and add the parameter -Xmx256M to the call to
java. Ask on a tomcat specific list, this is getting somewhat off topic

To increase JVM memory, just change your FOP.bat or whatever script starts
your Java VM and specify command line parameter -Xmx256M. The default is
64Mb,
which isnt sufficient due to the large number of glyphs in The Arial
Unicode font.

Out of Memory problem
I am trying for one Chinese PDF. When i do not make use of Arial Unicode MS font then i do not get this error. All chinese characters are displayed as #. Once i use thisfont then i get this error (even if it is just 2-3 pages long - sometimes at very beginning i get the 1 page report - after that even not that) I tried the the things mentined such as reduce the size of image, page sequence (do not know how to increase the JVM memory on fly) - also reset the Cache etc what ever given in docs, but still same. The report is all full with chinese characters. On logger i do not see anything but on jsp page i getjava lang out of memory error.
