Thread: [Php-java-bridge-users] NoSuchMethodError & NoClassDefFoundError

Hi,

I'm trying to upgrade JavaBridge in existing web apps (though this fact 
may not be a criteria for the problems arising).

I've downloaded the current 4.2, resp. 3.2, version, extracted 
JavaBridge.war and copied its contents into the web app. Aditionally, I 
copied JavaBridge.jar to the CLASSPATH (jre/lib/ext in this case, which 
is the only CLASSPATH).
There is no JavaBridge.jar in Tomcat's /common/lib, and JavaBridge.jar 
in ext and in /WEB-INF/lib are equal.

OK, with 4.2, I'm getting the follow error:

2007-08-15 17:55:03,257 [http-80-Processor23] ERROR 
php.java.bridge.JavaBridge - JavaBridge exception
java.lang.NoSuchMethodError: 
php.java.bridge.http.ContextServer.getCredentials(Ljava/lang/String;Ljava/lang/String;)Lphp/java/bridge/http/ContextFactory$ICredentials;

    at

    ...

Looking at the sources, the error occurs in PhpJavaServlet.java, in line 
212. And right, ContextServer.java contains a different signature of 
getCredentials().

With 3.2, there is another error: (BTW, JavaBridge.war, when deployed, 
throws the same error on load.)

    ...

Looking at the classes contained by JavaBridge.jar, there is no such 
class, indeed.

- How should I proceed?

Thanks
Robert

Hi,

Well, simply nuke the CLASSPATH and use a single repository. The PHP/Java Bridge offers this
as the default, please see the README for details.

Hi Jost,

thanks for your reply.

I already made sure three times anything in the CLASSPATH is OK. Else I 
wouldn't have posted.

Actually, please look at the sources you've deployed, and if they would 
compile.
As for version 4.2.2, they will not - as there's that inconsistency 
between a distinct method call, and signature (

ContextServer.getCredentials())

, I've mentionend in my previous post. - The sources won't compile, and 
the binaries (don't know how they have been compiled) throw the 
appropriate error.

Please take a deep breath and look into this.

Thanks again, and best regards
Robert

Which sources?  The sources from the CVS head or the src.zip from the download?

Hi Jost,

src.zip from the current 4.2 download.

However, I've just had another look at the sources, and I can't find any 
inconsistency anymore. I apologize.

Moreover, that update process of mine had succeeded in the meantime 
(there had been other old Java Bridge JARs in the CLASSPATH, which 
caused the problems, apart from JavaBridge.jar itself, which, before, I 
had replaced, exclusively).
Like you've mentioned, the webs will run with local dependencies on the 
Java Bridge, only, and they do, indeed.

Thank you sincerely for providing and supporting PHP/Java Bridge. 
Getting really good software and support - and for free - is not a 
matter of course. I'm most thankful for that.

Robert

Thanks and sorry. On another computer it works, thus, it works, in general.
