Debugging Roller in Eclipse

Hi,

I've been customizing Roller for a while now, and just wanted to know
if it's possible to set-up Roller to be debuggable in Eclipse.  I've
got various (simpler) Java/Struts/Tomcat projects in Eclipse which I
can use the Eclipse built-in debugger, but I've never been able to get
Roller using it.  Just wanted to know whether to continue trying to
get this working, or if it's not possible.

Thanks in advance for your help.

Cheers,

Richard

Hi Richard,

I usually use a remote debugger, which seems to work pretty well with
roller:

Hi Richard,

I think I already suggested remote debugger ;-)

Re: Debugging Roller in Eclipse

Posted by Dave <sn...@gmail.com>.

I would suggest that you start the Java VM that runs Roller, then
"attach" to it with the Eclipse debugger. Works great in Netbeans ;-)

RE: Debugging Roller in Eclipse

Posted by Adib Saikali <ad...@programmingmastery.com>.

Hi Richard,

Looks like roller is not able to find the properties files you are getting
an excetion in java.util.properties this would indicate to me that perphaps
the .proprties files are not being copied into the WEB-INF classes
directory.

Look in the .metadata\.plugins\org.eclipse.wst.server.core you should find
some temp directoris there, this is where eclipse will put the .class files
and other project resources. Search in there to see if roller.properties is
there. 

I highly recommend you upgrade to Eclipse 3.3 its much better than 3.2.  

Adib

Hi,

I've been trying to get Roller debuggable in Eclipse as described in
this thread by Adib.  I've got a simple servlet project working using
the same method, but when it comes to Roller I can't get it deployed.

I'm using Roller 3.1, Eclipse 3.2 and Tomcat 5.5 on Ubuntu.  I have no
problem deploying Roller as a Tomcat webapp on its own, but getting it
deployed and debuggable through Eclipse is a different matter.  I have
set-up 'Dynamic Web Project' and followed the steps as provided by
Adib, but when I go to run/debug the application in Eclipse, Tomcat
fails to deploy the webapp.  The roller.log reads:

If any Roller + Eclipse developers out there have any suggestions...
it would be greatly appreciated.

Re: Debugging Roller in Eclipse

Posted by Richard Jones <fu...@gmail.com>.

Thanks Adib,

I think I've found the problem with Eclipse crashing.  I'm using 64
bit java and the 64 bit version of Eclipse... after reading some
articles on the web it appears that a lot of people are having
problems with this combination and recommend using both 32 bit java
and 32 Eclipse.  Having just installed both, Eclipse + Tomcat +
Debugging are running smoothly and using very little resources.

Thanks again for all your help.

Regards,

Richard

RE: Debugging Roller in Eclipse

Posted by Adib Saikali <ad...@programmingmastery.com>.

Great good to hear that you have it running. I have never had the problem
with running out of memory on eclipse. However, I have only used Eclipse on
windows. 

When you debug an app eclipse will launch a JVM for the app seperate from
the JVM that is running Eclipse. So are you runnig out memory in the JVM
runnig Eclipse or the JVM runnig your app. 

If you are running out of memory in the Eclipse JVM check your command line
angs I have always made typos and thought I had given it more memory when I
had a typo and it was running with the default memory. If you want you can
run the JVM with -XX:-PrintGCDetails to see how often the GC is kikcing in
and what is causing you to run out of memory
http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp 

For the tomact config under installed runtimes there should be a drop down
list to select which JRE to launch tomact with, if you click on the
propreties for the JRE you can specify the command line options the JVM that
eclipse uses to launch roller, and of course also specify the
-XX:-PrintGCDetails to get output on GC activity. 

If none of the above two steps works, I would search the Eclipse forums to
check if SWT on linux is leaking memory. 

Cheers
Adib

Subject: Re: Debugging Roller in Eclipse

Many thanks again for the replies...  I've now got Roller Debugging
using the built-in Eclipse debugger as set-out by Adib.

Here's what I had to do:

1. Build Roller
2. Create a new 'Dynamic Web Project'
3. Copy from Roller 'build/webapp/*' into the 'WebContent' directory.
4. Create a 'resources' source folder.
5. Move 'WebContent/WEB-INF/classes/*' in the 'resources' source folder.
6. Copy from Roller 'src/*' into the 'src' folder.
7. Copy from Roller 'build/compile/business/*' into the 'src' folder.
8. Copy from Roller 'build/compile/web/*' into the 'src' folder.
9. Remove 'WebContent/WEB-INF/lib/roller-*.jar'.
10. Create a simple 'context.xml' file in 'WebContent/META-INF/' with
the database connection string.
11. Run using 'Debug on Server' (and set-up the necessary Tomcat server).

That's seem to have done it, however...  on my system when I run the
Roller in Debug mode it is incredibly slow and will always end-up
crashing Eclipse (not so good).  I've made sure both Eclipse and
Tomcat are using the Sun JDK (1.5).  I've also tried playing around
with the memory allocation for both Eclipse and Tomcat.  I have 2GB to
play with and whatever I do, Eclipse ends-up crashing.  I'm running
Ubuntu 7.04 (dual AMD-64).  When debugging Roller in Eclipse, both
CPU's will be maxed-out and whatever memory I've allocated will be
eaten up by Eclipse.   Any ideas anyone?  If it's a matter of getting
some more memory I'll go and buy it now, but before I do I wanted to
ask here.

Thanks again.

- Richard

Re: Debugging Roller in Eclipse

Posted by Richard Jones <fu...@gmail.com>.

Many thanks again for the replies...  I've now got Roller Debugging
using the built-in Eclipse debugger as set-out by Adib.

Here's what I had to do:

1. Build Roller
2. Create a new 'Dynamic Web Project'
3. Copy from Roller 'build/webapp/*' into the 'WebContent' directory.
4. Create a 'resources' source folder.
5. Move 'WebContent/WEB-INF/classes/*' in the 'resources' source folder.
6. Copy from Roller 'src/*' into the 'src' folder.
7. Copy from Roller 'build/compile/business/*' into the 'src' folder.
8. Copy from Roller 'build/compile/web/*' into the 'src' folder.
9. Remove 'WebContent/WEB-INF/lib/roller-*.jar'.
10. Create a simple 'context.xml' file in 'WebContent/META-INF/' with
the database connection string.
11. Run using 'Debug on Server' (and set-up the necessary Tomcat server).

That's seem to have done it, however...  on my system when I run the
Roller in Debug mode it is incredibly slow and will always end-up
crashing Eclipse (not so good).  I've made sure both Eclipse and
Tomcat are using the Sun JDK (1.5).  I've also tried playing around
with the memory allocation for both Eclipse and Tomcat.  I have 2GB to
play with and whatever I do, Eclipse ends-up crashing.  I'm running
Ubuntu 7.04 (dual AMD-64).  When debugging Roller in Eclipse, both
CPU's will be maxed-out and whatever memory I've allocated will be
eaten up by Eclipse.   Any ideas anyone?  If it's a matter of getting
some more memory I'll go and buy it now, but before I do I wanted to
ask here.

Thanks again.

RE: Debugging Roller in Eclipse

Posted by Adib Saikali <ad...@programmingmastery.com>.

Hi Richard,

I looked at the code in roller 3.1 and the code that is broken is indicated
with --> below.

version.properties is located in roller-business.jar file, the stack trace
tell me that the eclipse tomcat launcher does not have roller-business.jar
in the classpath.  a couple of things to check

1) Do you have roller-business.jar in WebContent\WEB-INF\lib ?
2) do a clean build and publish of the server 

I don't like to do remote debugging and have not had to do it since Eclipse
2.2 I prefer to setup my projects in way that is optimized to work with
Eclipse, which for me is the best IDE I have ever used. I love the fact that
I don't have to run a script, or hit a button to compile my code. 

 public RollerContext() {
        super();
        
        Properties props = new Properties();
        try {
   -->
props.load(getClass().getResourceAsStream("/version.properties"));
        } catch (IOException e) {
            mLogger.error("version.properties not found", e);
        }
        
        mVersion = props.getProperty("ro.version", "UNKNOWN");
        mBuildTime = props.getProperty("ro.buildTime", "UNKNOWN");
        mBuildUser = props.getProperty("ro.buildUser", "UNKNOWN");
    }

Hi,

I've been trying to get Roller debuggable in Eclipse as described in
this thread by Adib.  I've got a simple servlet project working using
the same method, but when it comes to Roller I can't get it deployed.

I'm using Roller 3.1, Eclipse 3.2 and Tomcat 5.5 on Ubuntu.  I have no
problem deploying Roller as a Tomcat webapp on its own, but getting it
deployed and debuggable through Eclipse is a different matter.  I have
set-up 'Dynamic Web Project' and followed the steps as provided by
Adib, but when I go to run/debug the application in Eclipse, Tomcat
fails to deploy the webapp.  The roller.log reads:

If any Roller + Eclipse developers out there have any suggestions...
it would be greatly appreciated.

Here is an example: If visitors to your site come via both
www.example.com and example.com and you prefer the example.com, then
you might want to set the absolute URL to http://example.com/ to
ensure that all links that Roller generates use the same URL.

Thanks Dave, that was very helpful, I think I have solved the problem it may
have been related to some issues with DNS and my tomcat configuration, I
have moved servers again and problem appears to have gone away.

Is it a roller best practice to setup the absoulte URL propert? Can you give
an example of what situations you should set it up under?

Thanks

This should give you the value set in the database.
   select value from roller_properties where name='site.absoluteurl'

If the value is not set in the database, then Roller determines the
site URL by examining the requestURL that comes from the first request
that hits the system.

How does roller compute $url.absoluteSite

Posted by Adib Saikali <ad...@programmingmastery.com>.

Hello Roller Developers,

I am wondering how $url.absoluteSite works in roller 3.1. I have a strange
bug on my roller implementation which I have tracked down to
$url.absoluteSite not working correctly, but I have not been able to find
why.

How the problem shows up:

1. on my site $url.absoluteSite keeps returning test.sereneambition.com
rather than www.sereneambition.com for a while I ran the roller 3.1 on
test.sereneambiton.com while I was testing it but now that I have switched
to production it still shows up. for example, when I log in as admin all the
URLs to the roller site show up as test.sereneambition.com, 


So far I have done the following.

1. Searched all the data in the database for test.sereneambition.com. I did
this by doing a pg_dump and then doing a search on the dump, so I know that
I searched all tables.

2. I turned on debug on the org.apache.roller.ui.core.filters.InitFilter and
the debug file shown that the filter was calculating the site
$url.absoluteSite correctly 

3. As I was reading various sources I got to the following method
RollerRuntimeConfig.getAbsoluteContextURL() and ended searching my whole
generated war file to see if site.absoluteurl is set to anything and I did
not change it from the defaults.

 public static String getAbsoluteContextURL() {
        
        // db prop takes priority if it exists
        String absURL = getProperty("site.absoluteurl");
        if(absURL != null && absURL.trim().length() > 0) {
            return absURL;
        }
        
        return absoluteContextURL;
    }
    
So how does this method work how does the db prop take priority. Is the
absolute URL somehow encoded in the database so that when I searched for it
did not show up. What could cause it to consistently return
test.sereneambition.com jut because I created the blog on a test server that
was hosted on that url?

Any help is appreciated

Re: Debugging Roller in Eclipse

Posted by Richard Jones <fu...@gmail.com>.

Hi,

I've been trying to get Roller debuggable in Eclipse as described in
this thread by Adib.  I've got a simple servlet project working using
the same method, but when it comes to Roller I can't get it deployed.

I'm using Roller 3.1, Eclipse 3.2 and Tomcat 5.5 on Ubuntu.  I have no
problem deploying Roller as a Tomcat webapp on its own, but getting it
deployed and debuggable through Eclipse is a different matter.  I have
set-up 'Dynamic Web Project' and followed the steps as provided by
Adib, but when I go to run/debug the application in Eclipse, Tomcat
fails to deploy the webapp.  The roller.log reads:

If any Roller + Eclipse developers out there have any suggestions...
it would be greatly appreciated.

Cheers,

Richard

Many thanks guys!

I'm going for Adib's method and I'm some making progress (although the
15 minutes past a long time ago ;-)   I will post again when I either
get it working or give-up and have a question.

Thanks again.

RE: Debugging Roller in Eclipse

Posted by Adib Saikali <ad...@programmingmastery.com>.

Hi Richard,

I have done all my customization to Roller in Eclipse, including debug. You
should be able to get setup in about 15 minutes. Here is how I did it.

Environment:
  - Eclipse Europa, with web tooling 
  - Tomcat 6.0.13
  - postgres 8.2.4
  - windows xp
  - roller 3.1 

Steps to create the setup.

1. Create Dynamic Web Project in Eclipse 

2. from the roller unzip dir copy webapp\roller\* into WebContent in Eclipse

3. Create a source folder called resources 

4. Move the contents of WebContent\WEB-INF\classes into the resources
folder. This way you can make changes to .properties files and eclipse will
put them automatically into WEB-INF\classes

5.Create a source folder for your code, and put your customizations there.
In my case I have only added models and changed some tags in roller for
example the calendar tag to change the arrow buttons on it. My favourite
method is to link the roller jars into the roller sources eclipse can do
easily, that way you can navigate through the roller code easisly via
eclipse shortcuts. Once I can navigate the code out I create my own models
in my own packages which don't interfer with roller, that way I don't have
to touch and recompile the roller intself.

6. If you want to make more major changes to roller, I would delete the
roller specific jar files from WEB-INF\lib and then unzip the source code
into a normal eclipse source folder, then hack on it as much as you want. 

7. In WebContent\META-INF put a tomcat context.xml which points to your
local database 

8. Right click on the projcet > Run AS > Server Application and you will be
able to do debugging, hot code replace and all other great stuff you are
used to doing with roller. 

hope this helps you
Adib

Subject: Debugging Roller in Eclipse

Hi,

I've been customizing Roller for a while now, and just wanted to know
if it's possible to set-up Roller to be debuggable in Eclipse.  I've
got various (simpler) Java/Struts/Tomcat projects in Eclipse which I
can use the Eclipse built-in debugger, but I've never been able to get
Roller using it.  Just wanted to know whether to continue trying to
get this working, or if it's not possible.

Thanks in advance for your help.

Cheers,

Richard
