[Php-java-bridge-users] Very first call to PHPJavaBridge fails

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

Hi all,

I've set up the PHPJavaBridge standalone as a windows service to 
implement lucene search capabilities in my PHP application.
After having started the Bridge with SERVLET_LOCAL:8080 the very first 
call to my script fails.
Here's what I can see in my SOAP Client:

<faultcode>SOAP-ENV:Server</faultcode>
         <faultstring>Broken local connection handle fwrite() [&lt;a 
href='function.fwrite'>function.fwrite&lt;/a>]: send of 6 bytes failed 
with errno=10054 Eine vorhandene Verbindung wurde vom Remotehost 
geschlossen.</faultstring>

Which means an existing connection has been closed by the remote host.
Every additional call is made with success, only the the first time 
fails. I assume the call to java_autoload(..) fails the first time.

here's my PHP function that encapsulates lucene searching:
++++++++++++++++++++++++++++++++++++++++++++++
    public function SearchIndex ($maxrows, $searchstring) {
        /**
        * @desc Search in a lucene index
        *      
        */
        try {
        require_once ($this->javabridge_root."/Java.inc");   
        java_autoload("lucene-core-2.9.1.jar;lucene-analyzers-2.9.1.jar");

        $analyzer = new 
Java('org.apache.lucene.analysis.standard.StandardAnalyzer');
        $indexer = new 
Java('org.apache.lucene.search.IndexSearcher',$this->indexfilename);

        //Lese alle indizierten Felder aus dem Index aus
        $Felder_ind = 
java('org.apache.lucene.index.IndexReader$FieldOption')->INDEXED;
         $IndexReader = 
java('org.apache.lucene.index.IndexReader')->open($this->indexfilename);
         
$AlleSuchfelder=java_values($IndexReader->getFieldNames($Felder_ind)->toArray());
         $IndexReader->close();

          //Eine Suche über alle im Index vorhandenen Suchfelder
         $parser = new 
Java('org.apache.lucene.queryParser.MultiFieldQueryParser', 
$AlleSuchfelder,$analyzer);
        }  
        catch (Exception $e) {
            throw new Exception(utf8_encode($e));
        }
                  
       $hits = array(); 
       try {
              if ($searchstring)   {
             
           
             
                $sortfield= new 
Java('org.apache.lucene.search.SortField','releasedate',3, true);
                $sorter= new

                //$sorter->setSort($sortfield);
                $query = $parser->parse($searchstring); 
                $hits = $indexer->search($query,$sorter );
                $num=java_values($hits->length());

                 //printf("3) Hits: %d\n", $num);
                 if ($num < $maxrows) {
                   $maxrows = $num;
                 }
                 $soapreturn = array();
                 for ($i = 0; $i < $maxrows; $i++) {
                     $found = $hits->doc($i);
                    $si = new SOAPSearchResult();
                    $si->wiretextId = 
utf8_encode($found->get('wiretextid'));
                   
                    $soapreturn[] = $si;
                 }

Hi,

can you please fetch Java.inc directly from the back end (require_once("
http://localhost:8080/JavaBridge/java/Java.inc") to make sure that your back
end version matches the version of the Java.inc library?

BTW: Why don't you install tomcat to run java as a service?

Thank you, Jost.
What do you mean by "fetch directly from the backend"? What's the 
backend here?
I'm using a symfony PHP framework and can configure the path to the 
PHPjavaBridge installation in a variable very easily.
That's the $this->javabridge_root variable. It contains a path to my bridge.
The java.inc is located in that directory.

I'm not allowed to use a tomcat although I'd like to have it.

Use the require command I have given. Please fetch Java.inc directly
from the back end, use

<?php require_once("http://localhost:8080/JavaBridge/java/Java.inc");
...
?>

Or make sure that the version of your Java.inc matches the version of
your back end.

The PHP/Java Bridge application.

Which seems to be the problem here. You have probably confused the
versions. Or the Java daemon you have written crashes immediately.


> I'm not allowed to use a tomcat although I'd like to have it.

Interesting. I thought you were running the back end as a daemon.
