Hi, I'd like to use the pygments syntax highlighting module from within a JAVA application. I understand how I can use the PythonInterpreter to execute single python statements or whole files. However I don't understand how I can load the whole pygments module and use it. In order to deploy the application easily I don't want to install Jython on the system and then call pygment's installer from the jython shell. I just want to deploy the jython jar archive and the pygments module (as egg file) and then load the module once during startup. Is this possible? Thanks in advance for your help. Cheers, raymi |

Greg, thanks for your reply. I tried to copy the pygments folder to my lib directroy, however the module wasn't found ("from pygments import highlight" failed). Can you explain how the directory structure would look like, i.e. which folder of the pygments module I will have to copy to what location? My application is a web application, so the structure looks as follows: /WEB-INF/lib jython.jar Thanks for your help, Dominik Moore, Greg schrieb: > Have you tried putting the pigment files in the Lib directory of the jar > file? > > Greg. > > > -----Original Message----- > From: jyt...@li... > [mailto:jyt...@li...] On Behalf Of Raymi > Sent: Saturday, July 26, 2008 7:42 AM > To: jyt...@li... > Subject: [Jython-users] Using Python Module (pygments) with Java > > Hi, > > I'd like to use the pygments syntax highlighting module from within a > JAVA application.

Hi Dominik, What I as referring to was to put the files _inside_ the Jython.jar. But I'm not sure if that's good advice in an app server environment but it worked for my standalone app. Sorry but I don't have a lot of experience using Jython with web apps. Maybe this would be of more help http://seanmcgrath.blogspot.com/JythonWebAppTutorial.html Greg. -----Original Message----- From: jyt...@li...

We use jython from a webapp, but its use is embedded within the servlet, rather than being the servlet itself (so we don't have a mapping from *.py to a PyServlet). It's been awhile since I had to get this working, but I had to add some code to our ContextListener to point jython in the right place when the servlet starts up. Our directory structure is very similar to Sean's. In contextInitialized(): System.setProperty("python.home", sc.getRealPath("/WEB-INF/lib")); We also run our own scripts, which are bundled with the .war file... I also added: System.setProperty("python.path", sc.getRealPath("/WEB-INF/lib/scripts")); so that it could find them.

Hi all, thanks for your hint Andy. I copied the jython Lib folder to /WEB-INF/lib/, copied the pygment module there as well and set the python.home path with System.setProperty and - WOW! - it works. Thanks a lot for all your help. There were (and are) some issues left that are not related to the original question but to compatiblity issues between the jython version and the pygments version (I had to use jython 2.5 alpha and am not able to parse python code with pygments due to a strange unicode error). But it's not that bad at the moment. Thanks again all of you for helping me with this thing. Cheers, raymi Michael Chisholm schrieb: > Where "sc" is the servlet context object.

Hello all, a followup question about this: System.setProperty("python.home", sc.getRealPath("/WEB-INF/lib")); That's a global property, right? What will happen when multiple applications running on the same server set this property to different values? Especially, what will happen to sys.path? I'm asking because I sometimes run into trouble with Jython module search paths when multiple applications (packaged as zipped .war files, and usually including the Jython 2.2 standalone .jar) run on the same application server. To me it looks like only the first app to be deployed has a chance to set the Python home, and all apps deployed later will use that home folder and sys.path. Which means that, if I put app-specific modules into /WEB-INF/lib/Lib/..., only the first app can find its modules. What I usually do to work around this is to create an extra folder for the app's modules and add that folder to sys.path explicitly in every application, but this feels really tedious and error-prone. Also, I have to be very careful not to have two modules with the same name in two different apps, because then again the order of deployment can become an issue. If you fully control the app server, you can always work around this, but let's assume a mutual customer of Raymi and me puts his app and mine on the same app server and expects both to just work. If my app loads first, his app won't find its modules, and vice versa, right? Any thoughts on this?

Hi, I see your problem. I'm not sure whether it would help, if one uses the following lines to set python.path instead of setting the system property directly: Properties props = new Properties(); props.put("python.home", pythonPath); PythonInterpreter.initialize(System.getProperties(), props, new String[] {}); However I don't know how PythonInterpreter.initialize is implemented and whether it will have side effects to other web applications if you do it. What I have also seen on the internet when investiagting this topic was code that added the application's lib directory to sys.path with python (i.e. pythonInterpreter.exec("import sys") and so on) and removed it explicitly after the script was executed. But that looks like a real workaround for me.

My experience is that if you put the stand-alone jython.jar in your WEB-INF/lib directory, you don't have to set python.home. That jar *is* your python home. And, if you use the modjy and its default settings, you don't have to set sys.path either. Your main application .py file is by default searched for in your servlet context root directory, and therefore that directory gets added to sys.path when your application runs. That makes configuration very simple. So, for my Jython webapp that uses modjy and the stand-alone Jython jar, the directory structure looks like this: mywebapp/ WEB-INF/ web.xml lib/ jython.jar (stand-alone version) modjy.jar Other Java jar files as needed dispatch.py Other Python files and packages as needed *.html, *.ini, etc. And my web.xml file: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name>mywebapp</display-name> <description> My Jython/Java Web application </description> <servlet> <servlet-name>modjy</servlet-name> <servlet-class>com.xhaus.modjy.ModjyJServlet</servlet-class> <init-param> <param-name>app_filename</param-name> <param-value>dispatcher.py</param-value> </init-param> <init-param> <param-name>cache_callables</param-name> <param-value>1</param-value> </init-param> <init-param> <param-name>exc_handler</param-name> <!--<param-value>testing</param-value>--> <param-value>standard</param-value> </init-param> <init-param> <param-name>reload_on_mod</param-name> <param-value>1</param-value> </init-param> <init-param> <param-name>log_level</param-name> <param-value>debug</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>modjy</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app> And inside dispatcher.py: def handler(environ, start_response): """The WSGI handler "callable object".

Yes, it is a static method, but as long as you deploy the jython.jar separately for every web application (i.e. /WEB-INF/lib of the application), the class is loaded multiple times, since Tomcat for example uses a different classloader for every web application. Well, it has to, otherwise you couldn't use static variables in a useful way at all.

Sounds reasonable, but that's not how my applications seem to behave. Could this be a problem with my app server? It's JBoss 4.0.3 (and I'm not in a position to change that). I'm positive that my apps use only a single "instance" of the static sys.path ... because when I do "import sys; print sys.path" at the top of my servlet, I get listings like the following: 16:30:52,506 INFO [Server] JBoss (MX MicroKernel) [4.0.3SP1 (build: CVSTag=JBoss_4_0_3_SP1 date=200510231054)] Started in 2m:16s:782ms 16:30:54,521 INFO [STDOUT] ['C:\\jboss\\server\\default\\.\\deploy\ \app1.war\\WEB-INF\\lib\\Lib', '/C:/jboss/server/default/deploy/ app2.war/WEB-INF/lib/jython-221-standalone.jar/Lib', '__classpath__', 'C:\\jboss\\server\\default\\.\\deploy\\app2.war\\', 'C:\\jboss\\server \\default\\.\\deploy\\app2.war\\WEB-INF\\jython'] In the past I've tried fiddling with all sorts of classloader settings to make JBoss load the apps separately, but that didn't change the "sharing" effect. I used instructions from http://wiki.jboss.org/wiki/ClassLoadingConfiguration and put files like this in WEB-INF/jboss-web.xml, for example: <jboss-web> <class-loading java2ClassLoadingCompliance="false"> <loader-repository>app1:app1=app1-loader</loader-repository> <loader-repository-config>java2ParentDelegation=false</loader- repository-config> </class-loading> </jboss-web> Regards Stefan On 2008-07-30, at 16:31 , Raymi wrote: > Yes, it is a static method, but as long as you deploy the jython.jar > separately for every web application (i.e. /WEB-INF/lib of the > application), the class is loaded multiple times, since Tomcat for > example uses a different classloader for every web application. > Well, it > has to, otherwise you couldn't use static variables in a useful way > at all. > > Stefan Eischet schrieb: >> Raymi: PythonInterpreter.initialize is a static method, so I'm afraid >> that is more or less the same as setting the system property. >> >> David: modjy sounds very interesting; I've never used it but I'll >> give >> it a try ASAP.

Raymi: PythonInterpreter.initialize is a static method, so I'm afraid that is more or less the same as setting the system property. David: modjy sounds very interesting; I've never used it but I'll give it a try ASAP. Could make my life much simpler in the long run, though it'll take some time to port all those servlets to WSGI. You mention "other Python files and packages as needed" - do you have to do anything special to help Jython find the packages, or is it sufficient to add a folder "mywebapp/mypackage" and put (at least) an __init__.py file there? Thanks a lot for the suggestions!

By default, modjy runs your main application .py file in your servlet context root. So yes, that means that you can just add a Python package directory to your servlet context root and your application can import it without trouble. I'm looking forward to the day when Jython 2.5 can just run cherrypy's WSGI server without modification. Then I'll throw away my hand-rolled WSGI-based framework. > -----Original Message----- > From: jyt...@li...

No, I don't use modjy. I use plain java servlets with Tomcat (no Apache). Leo Soto M. schrieb: > On Tue, Jul 29, 2008 at 5:08 AM, Raymi <ra...@gm...> wrote: > >> Greg, >> >> thanks for your reply.
