RE: How can i display only the latest version of article in Journal portlet

2009-03-11T07:26:53Z

Hello,

spontaneusly I would say, the simplest way is to expire all the úprevious versions of the article :-) But You probably know it - if You want the different behavior of the journal contant portlet than the default one, You have to possibly develop a new/different portlet or just to modify the functionality of the default one.

CAS integrate with Liferay portal 5.2.1

2009-02-13T13:40:56Z

hai to everyone.

i am trying to integrate CAS(Central Authentication Service) with Liferay portal 5.2.1. and i followed the below steps.

i copied the cas-server-3.2.1 into Liferayportal/tomcat/webapps folder,and i placed casclient.jar file in Liferayportal/tomcat/webapps/root/WEB-INF/lib folder.

then i generate the sslcertificate key using RSA Algorithm.

i use the below commands.

keytool -genkey -alias tomcat -keypass changeit -keyalg RSA
this command is used to generate the .keystore file in c:/documents and settingd/Nagi.Yedula/liferay folder.

Then i copied the .keystore file into my own file.
keytool -export -alias tomcat -keypass changeit -file %FILE_NAME%

Then i used the below command to make certificate as trusted.
keytool -import -alias tomcat -file %FILE_NAME% -keypass changeit -keystore %JAVA_HOME%/jre/lib/security/cacerts

Then i modified the web.xml file in webapps/root/WEB-INF/lib folder.
i added the CASFilter.

the i enable the SSL connector in server.xml of tomcat folder.

Then i start the Liferat tomcat serverthen i hit the http://localhost:8080/
then i click signin in menu.it was redirect to below url

https://localhost:8443/cas-web/login?service=http%3A%2F%2Flocalhost%3A8080%2Fc%2Fportal%2Flogin.

then browser saying.
localhost:8443 uses an invalid security certificate.

The certificate is not trusted because it is self signed.

(Error code: sec_error_ca_cert_invalid)

if any body come across the problem.if any body found the solution.please let ma know.

Thanks

Check the "cacheable" checkbox in journal templates.

RE: How to Cache Liferay JOURNAL CMS Content

2009-01-26T05:38:32Z

Hello,

I do not know how it works exactly, but did You checked the functionality of the option "cacheble" by every template? From the description by tthis option I would guess the result display of the article in the page is cached if this is checed (so, not the article, but only the concrete visual interpretation of the article on the specified place) - I think, this is more important than the caching of the article itself.

There is made the caching of DB entities, so also of articles,e tc. if the cache is generally turned on...

Did You also tried following option?

#layout cache turned on - caches all guest pages:
com.liferay.portal.servlet.filters.layoutcache.LayoutCacheFilter=true

I still can´t avoid cache for some entities. Anyone could help please?

RE: Database access: no caching in some entitiesy do You set

2008-04-23T14:01:09Z

Hello,

why do You set

hibernate.cache.use_second_level_cache=false

?

I think, this should be true to enable the ehcache, containing the cached objects... The first level cache of hibernate keeps the objects only during the living Hibernate session, what is used during one request only. As far as i know the second level cache should contain the objects also between the requests...

with regards, Archie

I need to update the relations fields (foreign keys) with other entities (MyAccount-OtherEntity), data in MyAccount and I think I wont need to update the User fields, only read them.

I need then to have MyAccount with no cache.

I want to keep the cache for all the other entities.

value.object.finder.cache.enabled=true
value.object.finder.cache.enabled.com.liferay.portal.model.Layout=true
value.object.finder.cache.enabled.com.liferay.portal.model.User=true
value.object.finder.cache.enabled.Users_Roles=true
value.object.finder.cache.enabled.com.ext.portlet.myaccount.model.MyAccount=false

#
# Set other Hibernate cache settings.
#
hibernate.cache.use_query_cache=true
hibernate.cache.use_second_level_cache=false
hibernate.cache.use_minimal_puts=true
hibernate.cache.use_structured_entries=false

With this settings I have no cache for MyAccount, but also I have no cache for all other entities (I tested with User)

RE: Database access: no caching in some entities

Which fields are you updating?

RE: Database access: no caching in some entities

2008-04-21T12:38:40Z

One more remark - You could specify

#
# Set other Hibernate cache settings.
#
hibernate.cache.use_query_cache=false
hibernate.cache.use_second_level_cache=false

and not true, like You mentioned in Your post - this chould turn the cache off generally - but this is not a very good idea from performance reasons... I would rather try to turn off the second level cache, turn on the first level cache and then tunr off the cache specifically only by the entities which are updated from the second (legacy) system...

cheers, Archie

RE: Database access: no caching in some entities

2008-04-21T12:35:20Z

Hello,

I think, there is a possibility You could turn off the caching of the specified entities by modifying the hibernate configuration file

META-INF\portal-hbm.xml

in

webapps/ROOT/WEB-INF/lib/portal-impl.jar

- here You can set entity specific caching for hibernate.

But the seconf d problem is, there is used ehcache as a second level cache (it must be synchronized between the instances for example if You have more nodes in cluster) and I do not have any idea if it can be configured in this way... possibly you could by hibernate turn off the second level cache...

good luck, Archie.

Database access: no caching in some entities

2008-04-21T07:49:12Z

I have to integrate my portal developed in liferay with another application. Both applications have access to the User and MyAccount (additional fields for users) entities.

If I want to update one user fields from my other application, those changes are not seen in liferay because of the caching.

I want to define there is no caching for those entities.

I tried to define the portal-ext.properties

#
# Set other Hibernate cache settings.
#
hibernate.cache.use_query_cache=true
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_minimal_puts=true
hibernate.cache.use_structured_entries=false

#
# Value objects are cached by default. You can disable caching for all
# objects or per object.
#
# For mapping tables, the key is the mapping table itself.
#
value.object.finder.cache.enabled=true
value.object.finder.cache.enabled.com.liferay.portal.model.Layout=true
value.object.finder.cache.enabled.com.liferay.portal.model.User=false
value.object.finder.cache.enabled.Users_Roles=true
value.object.finder.cache.enabled.MyAccount=false

but doesn´t work. Any idea?
