php-java-bridge-users Mailing List for PHP/Java Bridge (Page 4)

Jost, you have been awesome. Thank you very much. I exploded the
JavaBridge.war in my weblogic applications folder and it deployed
flawlessly and I am able to see and execute some of the examples.

Now, here is my actual problem. I have a PHP script which encrypts a
couple of strings and throws out an encrypted token. 

The call looks like this in PHP: 

include("./library/class.Encryption.php");
$objEncrypt = new Encryption;
$token = $objEncrypt->EncryptArrayPublic($values,$public_key);

I need to use this in Java. In the sense that in my Java Class I need to
call the EncryptArrayPublic function in the Encryption.php script.

Is it possible using this Java/PHP bridge. If yes, please please, could
you give me a little insight into how I should do that? Including where
should I drop the PHP files and the syntax for calling these functions
in Java.

Thank you very much,
-Yugan

Hi,

Your AS is at least two generations behind. PHP/Java Bridge version 5
needs J2EE 1.4 and above. Please use PHP/Java Bridge version 4.x or 3.x
instead. Please see Gary Horen's article "Using PHP-Java Bridges with
WebLogic Server" for details.

Since WebLogic 8.1 all deployed .war applications cannot access their
file resources anymore; as getRealPath(...) always returns null. Please
explode your application .war file and deploy that.

I have tested PHP/Java Bridge 5.3.4 on WebLogic 8.1 on Windows and it
runs fine. Except that a) JSR 223 is not available, so all JSR 223
examples will fail, b) java.io.Closeable is not available, used by other
examples, c) the RequestListener is not available in servlet spec 2.3
which causes a failure during deployment and d)
application.getRealPath() always returns null when standard .war files
are being used, which causes a failure in some of the examples.

Jost Boekemeier

After I commented out the following:
<!-- Terminate invocable scripts when the JSP/framework request finishes

   <listener>
 
<listener-class>php.java.servlet.RequestListener</listener-class>
    </listener -->

JavaBridge got deployed successfully. 

But, when I accessed it at http://localhost:7001/JavaBridge/ I am
getting NullPointerException.

PS: I am using weblogic 8.1 so I think my servlet container is 2.3

Hi,

>javax/servlet/ServletRequestListener

could it be that your servlet container is old?  If so, simply remove
the listener declaration from the web.xml contained in JavaBridge.war.
It is not essential.

Thanks Jost.
I understand what you are saying. But, I haven't done any of that. i.e I
haven't created java.ext.dirs and copied the jars (I am assuming I need
to create that dir 'cos I don't see that existing already). 

The one and only step I did is trying to deploy the JavaBridge.war using
weblogic console.

If that is not sufficient and I need to create the java.ext.dirs where
should I create that? I have my WebLogic on Windows XP btw.

Also, I am using the latest bridge, downloaded yesterday.

Thanks much for your help.

Hi,

please see our FAQ entry "Why do I get a NoClassDefFoundError?", it
isn't very helpful, but it explains what went wrong.


In this particular case is was a packaging error in php-script.jar,
which contained an open reference to the servlet classes. There is not
problem with this per se, but the INSTALL.J2SE document stated that one
should copy php-script.jar to the java.ext.dirs, which leads to trouble
because the open reference cannot be resolved; the servlet classes are
loaded from a different loader by your J2EE server.

Please either remove the jar file from java.ext.dirs or copy all of your
classes to java.ext.dirs. 

Since version 5.3 the documentation has been revised and the JSR223
servlet classes have been moved to the php-servlet.jar.

However, the fundamental problem that Java doesn't have a decent module
system still exists.

Jost Boekemeier

I am getting the NoClassDefFoundError in my server logs when I try to
deploy the JavaBridge.war in my WebLogic server. I looked in the mailing
list for this error and I saw 1 guy getting this in tomcat. He
re-deployed his jre and tomcat for it to work. I don't want to
re-install my weblogic. Is there any other way to get around this? I
dropped the same JavaBridge.war in tomcat webapps and it picked it up
and deployed fine. Also, I went through the README section 'Java
Platform Issues' and I don't think it helps me.  Are there more steps to
follow to deploy JavaBridge in WebLogic?

 

Any help is greatly appreciated.

Hello!


Depending on your $analyzer, the MultiFieldQueryParser may not do what you expect it to do. See here http://mail-archives.apache.org/mod_mbox/lucene-java-user/200409.mbox/%3C04Sep7.180551pdt.%2258612%22...@sy...%3E

Hi,


> Interesting why would I get different results on the same
> search??

sounds like an application-level problem to me. The bridge passes the array values in order, so I don't think you can get random search results when running the same procedure twice. -- The bridge has successfully called your application method, everything below is outside of the scope of the PHP/Java Bridge.

Start Java via your favorite Java IDE (Eclipse, Netbeans, ...) and inspect the application state; if you think that there's a bug in your application, please report this to the application developers.


Regards,
Jost Boekemeier



      

Interesting why would I get different results on the same search??

If I just a QueryParser and not a MultiFieldQueryParser I get results.

When I do a MultiFieldQueryParser i am not getting any results.

I have tried the following and dont seem to be getting anything back: 

$parser = new Java( 'org.apache.lucene.queryParser.MultiFieldQueryParser',array('name','description'),$analyzer ); 

I have also tried: 
$parser = new Java( 'org.apache.lucene.queryParser.MultiFieldQueryParser',"name,description",$analyzer ); 

AND 
$parser = new Java( 'org.apache.lucene.queryParser.MultiFieldQueryParser',"name description",$analyzer ); 

OK I found the policy and now have this working.

I would first check that the user running this code (the Apache user for
