Web Content not displaying - weblogic 12c + oracle 11g

[mitziuro the cat，修改在11 年前。]

Hi,

We've created a site template that we use for creating a new sites.
But for some unknown reason some content(web content) starts to disappear after a while (the largest ones).

After some tests, we've noticed that if we add something very simple like

<p>aaa</p>

it's working (on any page using the default theme).
But if we increase the number of a's after we reach like 300+ a's the content it's not showed.
If we click edit we see the content without a problem.
If we click publish, the content it's not showed on the page.

The Liferay logs don't show any exception or warning.
We've started the weblogic server with root.
The html was validated with Dreamweaver.
The same html code if we put it on Tomcat/Mysql works even for 1000 letters of a

<p>aaaaa....aaa</p>

We belive that has something to do with the db but we are not so sure because we don't see errors in logs.
Any ideas, why?

We've the same issue
I think there is a conflict of libraries or application server configuration: if we connect a Tomcat to the same Oracle schema the webcontent is displayed

We're using CentOS.
Are u using the same os?
We've had some issues regarding Liferay on CentOS (some fixes for Sass in portal-ext), so it can be one of the problems.

Problem solved:
You have to instruct the classloader to use app's classes instead of weblogic's classes.

Add

<container-descriptor>
...
<prefer-web-inf-classes>true</prefer-web-inf-classes>

...
</container-descriptor>

in weblogic.xml inside the Liferay archive.

Hi Aku,
The weblogic.xml file is located inside the Liferay WAR file, and inside the WEB-INF folder.

Thank You "Jonas Choi". a very clear explanation.

I have no problem at localhost, this problem only occurred on the server.
