Jdeveloper 11.1.2 Fails to render web pages in Design Mode

Hi all!

I was facing some issues with this new Jdeveloper release (11.1.2) also called a "SHERMAN" release.
The problem seldom appears but probably did some developers to reinstall the tool. Here is a sreen of the bug in all of its glory:


This bug usually occurs when something is wrong with your web project in particular, but when I looked into other projects it was happening to everything loaded with Jdeveloper, so this is not a project-specific bug.

After some time working out with Jdev user directory (here I find it under C:\Documents and Settings\MY_WINDOWS_USER_NAME\Dados de aplicativos\JDeveloper\system11.1.2.0.38.60.17), deleting and moving directorys around I released that a specific directory was giving the issue, its name is "o.j2ee.jsplib".

Looks like this directory store some information about libs that IDE uses to visualize JSF components, like taglibs or something else.

You just have to delete this directory and let Jdeveloper recreate it for you on the next start. Something inside this directory was not letting Mojarra Library start, here is a screen with the issue corrected:

Possible reason for JBO-27019 - ADF Bussiness Components

Hi all, Today I was working a lot only running the Application Module by itself. I had a View Object that I implemented its Java View Row Class. After some time I decided to change one attribute from "String" to "Number", running the AppModule again was giving me the exception: oracle.jbo.AttrValException: JBO-27019: The get method for attribute "attributeName" in "ViewObjectName" cannot be resolved. Bored of trying to solve the error I created a new VO based on the same EO. The new VO worked, so, I compared both of them (the new one and the old one), one difference of course is the RowImpl class, I implemented it on the new VO too moved my comparisons to the Java RowImpl class. This lead me to a strange IDE bug, after changing a Entity Attribute it does not refactor the ViewRowImpl class (I know it is too far for the IDE to know that kind of information but the fact is that it does not send us any intelligent messages about the error).

ViewObject Forward Only mode

Hi! Today I was reading a interesting topic about one of ViewObject tuning properties, it is called Forward Only mode, you can programmatically set it by calling setForwardOnly(true). This property won't allow the ViewObject to cache the previous loaded rows while RowSet scroll is happening. Link to the documentation:  http://docs.oracle.com/cd/E21043_01/web.1111/b31974/bcadvvo.htm#sm0342 Section 39.2.6  Use Forward Only Mode to Avoid Caching View Rows As stated in documentation: "Often you  will write code that programmatically iterates through the results of a view object. A typical situation will be custom validation code that must process multiple rows of query results to determine whether an attribute or an entity is valid or not. In these cases, if you intend to read each row in the row set a single time and never require scrolling backward or re-iterating the row set a subsequent time, then you can use "forward only" mode to avoid caching the retr

Weird Weblogic deployment exception

Hi everyone! Just a note for myself, today I faced a weird exception while trying to start a Managed Server from our Weblogic Cluster. The server crashed due to an exception: java.lang.OutOfMemoryError: allocLargeObjectOrArray: [Ljava/lang/Object;, size 16400 I don't know exactly what hapenned, especially because the time that exception ocurred we had almost no users online. After trying to start the Managed Server I was facing this error: weblogic.management.DeploymentException: Exception occured while downloading files And then: Caused By: java.io.IOException: [DeploymentService:290066]Error occurred while downloading files from admin server for deployment request "0". Underlying error is: "null" After some Googling I found a blog post that helped me a lot: http://www.javamonamour.org/2012/10/javaioioexception-deploymentservice2900.html One special note to " and the Admin is unable to redeploy the file ".   After reading that I star
