Re: [Php-java-bridge-users] Shared Object (*.so) registration

[<php...@li...>]

Hi Jost,

Thank you for your anwser.I tried your suggestion and it didn't gave me that
error but i still don't get it to work.
It just says:
Cause: java.lang.ClassNotFoundException: Unresolved external reference:
java.lang.NoClassDefFoundError.


This is what i did:

moved libAspriseOCR.so to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/i386/client/libAspriseOCR.so
moved aspriseOCR.jar to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/ext/aspriseOCR.jar

restarted tomcat and apache

See my code below, Java code is directly copied from the manufactures
website:

/*

The original java code:


import com.asprise.util.pdf.PDFReader;
import com.asprise.util.ocr.OCR;

PDFReader reader = new PDFReader(new File("my.pdf"));
reader.open(); // open the file.
int pages = reader.getNumberOfPages();

for(int i=0; i < pages; i++) {
   BufferedImage img = reader.getPageAsImage(i);

   // recognizes both characters and barcodes
   String text = new OCR().recognizeAll(image);
   System.out.println("Page " + i + ": " + text);
}

reader.close(); // finally, close the file.
*/


// My php5 Code

$aJarFiles[] = "./external/lucene-demos-2.0.0.jar";
$aJarFiles[] = "./external/lucene-core-2.0.0.jar";
$aJarFiles[] = "./external/junit.jar";
$aJarFiles[] = "./external/checkstyle-all-4.2.jar";
$aJarFiles[] = "./external/bcprov-jdk14-132.jar";
$aJarFiles[] = "./external/bcmail-jdk14-132.jar";
$aJarFiles[] = "./external/ant.jar";
$aJarFiles[] = "./external/FontBox-0.1.0-dev.jar";

$aJarFiles[] = "./AspriseJavaPDF.jar";
$aJarFiles[] = "./aspriseOCR.jar";

java_require(implode(";",$aJarFiles));

$file = new Java('java.io.File',"./changes.pdf");
$reader = new Java('com.asprise.util.pdf.PDFReader',$file);
$reader->open();
$pages = $reader->getNumberOfPages();


for($i=0; $i < $pages; $i++) {

   $img = $reader->getPageAsImage($i);
   $ocr = new Java('com.asprise.util.ocr.OCR');
   $text = $ocr->recognizeAll($img);

   print $text;
}


Any idea what's wrong with my setup? i Put everything in a zip if you would
like to take a look:
