Re: Comments module:

2008-08-29T08:02:08Z

I did some research. The NullPointer is thrown here

org.apache.jsp.WEB_002dINF.jsp.offline.system.modules.com_alkacon_opencms_comments.elements.comment_005fmain_jsp._jspService(comment_005fmain_jsp.java:93)

so I checked the particular line and the code there is definately not from me

CmsCommentsAccess alkaconCmt = new CmsCommentsAccess(pageContext, request, response); // Errorline

Thanks. I solved it meanwhile. Had to include this line:

<%@ page import="org.opencms.lock.CmsLock" %>

Hi Marc,

If you copied and pasted from the PDF then you need to remove the line break
in your JSP after line:

"/system/modules/com.alkacon.opencms.comments/elements/comme

Thanks a lot for this module, I was really waiting for it.

Anyway, I having a small problem with it.
After installation, I created a configuration file without no problem.
Then I added a jsp to my page (the guestbook) since I dont want to have
directly in my template for now. I added the provided code, declared a
"comments" property and pointed it to the configfile.

When I try to display this page now, I get the message

What could be the problem about this.

You're mostly right. But you import types/classes, not packages. If
I've understood you right, you've used something equivalent to:

<%@ page import="org.opencms.lock" %>

In order to use »org.opencms.lock.CmsLockType.TEMPORARY« without
qualification as »CmsLockType.TEMPORARY«, add the following to your JSP
(note that the right class name is »CmsLockType« instead of »CmsLock«):

<%@ page import="org.opencms.lock.CmsLockType" %>

The servlet container (i.e. Tomcat) translates this to the import
declaration »import org.opencms.lock.CmsLockType;« before compilation.

OpenCms Logout with Websphere (redirect problems)

2008-08-29T03:45:02Z

Hello everybody,

At first sorry about my English, I am going to improve it in a course this year. The question is the next: I am trying to run OpenCms in a Websphere Server and after the corresponding configuration I have a problems with the redirection and the logout. In Tomcat there aren`t problems but in WebSphere the redirect after the OpenCms demo logout doesn't work. I read in other forums some answers refering about the WebSphere problems with redirection, and I change in the CmsWorkplace class the redirect of the method sendCmsRedirect to a Forward like this:

public void sendCmsRedirect(String location) throws IOException, ServletException {

// TOOD: IBM Websphere v5 has problems here, use forward instead (which has other problems)
// This is the old code before my changes...
// getJsp().getResponse().sendRedirect(OpenCms.getSystemInfo().getOpenCmsContext() + location);

setForwarded(true);

CmsUriSplitter splitter = new CmsUriSplitter(OpenCms.getSystemInfo().getOpenCmsContext() + location);
Map params = CmsRequestUtil.createParameterMap(splitter.getQuery());
sendForward(splitter.getPrefix(), params);

}

public void sendForward(String location, Map params) throws IOException, ServletException {

setForwarded(true);
// params must be arrays of String, ensure this is the case
params = CmsRequestUtil.createParameterMap(params);
CmsRequestUtil.forwardRequest(getJsp().link(location), params, getJsp().getRequest(), getJsp().getResponse());
}

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

And in CmsJspLoginBean class I change the method logout and put the next code (similar to login...):

public void login(String userName, String password, String projectName, String redirectUri) throws IOException {

login(userName, password, projectName);
if (m_loginException == null) {
if (redirectUri != null) {
getResponse().sendRedirect(
OpenCms.getLinkManager().substituteLink(getCmsObject(), redirectUri, null, true));
} else {
getResponse().sendRedirect(getFormLink());
}
}
}

public void logout(String redirectUri) throws IOException {

HttpSession session = getRequest().getSession(false);
if (session != null) {
session.invalidate();
}
// logout was successful
if (LOG.isInfoEnabled()) {
LOG.info(Messages.get().getBundle().key(
Messages.LOG_LOGOUT_SUCCESFUL_3,
getRequestContext().currentUser().getName(),
getRequestContext().addSiteRoot(getRequestContext().getUri()),
getRequestContext().getRemoteAddress()));
}

if (redirectUri != null) {
getResponse().sendRedirect(
OpenCms.getLinkManager().substituteLink(getCmsObject(), redirectUri, null, true));
} else {
getResponse().sendRedirect(getFormLink());
}

}

After the changes, the problem still apear. The parameter ?path=/demo_en/extra/login.jsp after the logout in the url appear but the redirection doesn't work. I don't know what many things can I do.

Thanks you in advance for any help you can give,

In Java you import types (or static import for static functions). You
don't import packages. Therefore you schould use the following import
declaration:

import org.opencms.lock.CmsLock;

You could also use this import on demand declaration:

import org.opencms.lock.*;

What else resourceTypeNames are there besides "plain"? Would a google
sitemap file have to be structured contents? Or a plain sitemap.xml file?

Heyho,

Maybe type interference? There also exists org.opencms.workplace.commons.CmsLock.java

I solved it by typing

org.opencms.lock.CmsLock.TEMPORARY

Don't know, why including org.opencms.lock or org.opencms.* didn't work.

Re: Performance

We think it's the overhauled OpenCms 7 engine as well as the PostgreSQL update (8.3 is known for having great performance improvements). It has probably not that much to do with JDK/Tomcat upgrades.

Also, during the update we exported all OpenCms projects and re-imported them in the new OpenCms 7. This process dropped the whole resource history, which caused the database to drop from about 6 GB to 3 GB. This quite uncontrolled history mechanism still frightens me a bit. In a heavily changing environment it may inflate the size of your database more than you might like.

May I ask what's your impression?

What's the factor that you think could have affected the most to that
performance gain? Opencms version change or jdk-tomcat upgrade?

Objet : Re: [opencms-dev] Performance

We just did a migration for 4 of our servers similar to yours. We upgraded
like that:

OpenCms 6.2.3 -> 7.0.5
Tomcat 5.5 -> Tomcat 6 (latest)
SUN JDK 1.5 -> SUN JDK 1.6 (latest)
PostgreSQL 8.1 -> PostgreSQL 8.3.3
Apache 2.2.x as Proxy -> Apache 2.2.x with mod_jk

If you stick to OpenCms 7.0.5 (do not use any previous 7.x version, they have
major issues in their db code, at least for PostgreSQL), you should not
encounter any problems. At least we didn't.

The performance boost after the upgrade was incredible, so don't hesitate to
do it as soon as possible. As motivation, below is a link to a graph of our
server monitoring service (munin), showing the average page rendering time
before and after the update. As you can see, we updated in july. This is
remarkable, because this very server is a Dell PowerEdge Xeon quad core with
16 GB of RAM, which is lightning fast already.

Hello, Marc.

I have not met any problem with:

OpenCMS 7.0.4, 7.0.5
Sun JDK 1.6.0_05
Tomcat 6.0.16
Apache2-2.2.4,
mod_jk_1.2.26
Postgresql8.2.4

on different computers with 1Gb RAM.

But I have no such flow of queries, as you have and did not
compared performance of different versions of software.

Performance

2008-08-27T10:43:51Z

Hello everyone,

I'm planning to migrate from version 6 to 7.
As the systems performance is ok but could be
better, I'm also looking into improving the
configuration since the max. hits per hour
might soon double from now about 19000.
Currently it's running on Apache 1.3 with mod_jk, Mysql 4.0.24 with
jdk1.5_0_06. I was thinking about switching to the latest
Apache2, Tomcat 6 and Mysql 5 with latest jdk as well.
Does anyone have experience with that configuration?
Is it better to use Tomcat 5.5 as recommended in the installguide?
Should i also stick to Apache 1.3?
How about the jdk? Any known problems with the latest version?
I want to improve performance but off course stability is prio one.
The system is running on a P4 3.4 Ghz, 160 GB harddisk and approx.
900 MB ram. Probably i would get the biggest boost from moving
to a new server. Anyone got with a similar hardware?
Ram usage is always up to 890 of 900 which is surely not optimal !?
I gave about 750 mb to the jvm. Is that maybe even too much?
Lots of questions, any comments or links would be highly appreciated!
Many greetings
Marc

Re: creating a file

2008-08-27T06:24:16Z

We use OpenCms.createResource() for that (e.g. automatically creating Google Sitemaps every night).

Looks like that:

CmsObject cmso = ....
String filename = ...
String s_filecontent = ...
...

cmso.getRequestContext().setCurrentProject(cmso.readProject("Offline"));

if (cmso.existsResource(filename)) {
cmso.lockResourceTemporary(filename);
cmso.deleteResource(filename, CmsResource.DELETE_PRESERVE_SIBLINGS);
if (cmso.existsResource(filename)) {
cmso.unlockResource(filename);
cmso.publishResource(filename);
}
}
cmso.createResource(
filename,
OpenCms.getResourceManager().getResourceType("plain").getTypeId(),
s_filecontent.getBytes(),
new ArrayList()
);
cmso.unlockResource(filename);
cmso.publishResource(filename);

cmso.getRequestContext().setCurrentProject(cmso.readProject("Online"));

Basically it's deleting and creating the file over and over again. This works also in the latest OpenCms 6 versions (publishResource is deprecated as of version 7).

HTH,
Roman

Re: Recursive property search

2008-08-27T06:15:29Z

Hi Robert,

I'd recommend a manual processing and changing of these resources. Using the OpenCms API that's actually quite easy.
The most common (though slowest) approach is to recursively iterate through the OpenCms VFS and check resources for properties. You could try something like that:

public function recurseVFS(CmsObject cmso, String path) {
Iterator<CmsFile> iter_files = ((ArrayList)cmso.getFilesInFolder(path)).iterator();
while (iter_files.hasNext()) {
CmsFile file = iter_files.next();
CmsProperty p = cmso.readPropertyObject(file, "MyProperty", true);

// do something with the file and/or property here

Iterator iter_folders = ((ArrayList)cmso.getSubFolders(path)).iterator();
while (iter_folders.hasNext()) {
CmsFolder folder = iter_folders.next();
recurseVFS(cmso, cmso.getSitePath(folder));
}
}
}

You would initially call recurseVFS() with the VFS path you would recursively like to start with.

This functionality is backward compatible at least to OpenCms version 6.2.3.

HTH,
Roman

Hi all,

I have a situation in which I need to migrate property values automatically in order to preserve existing content and in order to reduce or completely avoid manual work on several thousand resources.

Let's say the property is called "MyProperty" and it currently contains values like "a,b,c", "b,c,a" etc. I want to convert them to "x,y,z", "y,z,x" etc.

As there can potentially be a deliberate number of freely chosen combinations, I can obviously not use the workplace tools to replace the property values.

Hence, I would like to recursively iterate over all VFS resources in a given site, read the property "MyProperty", save the current property value and the resource name if a resource has that property set, and then go to step 2 and replace the properties on the collected resources.

If this is programatically possible, can anyone give me a hint on where to start?

I work with OpenCms 6.5.6 which contains custom patches directly from Alkacon.

Have a nice day,
Robert

creating a file

2008-08-27T03:15:20Z

The answer may be simple but I would like to create and write to a file
in the VFS from within a jsp. Next time I invoke the jsp the file
should be newly written to if it already exists (old contents should be
overwritten).

Do I use CmsResource, CmsObject or CmsFile ?
