Jdeveloper Design Time issue fix


In Jdeveloper 11.1.2 we often see that the designer is going off and looks clumsy without the ‘WYSIWYG’ feature during the design time. The jspx or jsff designer in Jdeveloper will show as

To fix this we directly go and delete this directory o.j2ee.jsplib in

C:\Documents and Settings\ USER_NAME\ApplicationData \JDeveloper\system11.1.2.0.38.60.17

Thanks to the blogger

For other version, if the file or folder does not exist then go to o.j2ee and delete or move – jsp-faces-tags-cache.xml and jsp-libraries.xml. Also delete .wlLib folder if it exists. If nothing works delete the system folder.

also make sure that the ‘Execute Tags in JSP Visual Editor’ is checked for adf components

updates from a collegue
If you have a class reference in your application folder that cannot be loaded this problem might occur

possible fixes

change

oracle.adf.view.rich.security.FRAME_BUSTING
<param-value>differentDomain</param-value>

To:

<param-name>org.apache.myfaces.trinidad.security.FRAME_BUSTING</param-name>
<param-value>differentOrigin</param-value>

or

change the class .adf/META-INF/services/oracle.adf.view.rich.context.ExceptionHandler
or rename this file oracle.adf.view.rich.context.ExceptionHandler

jdevloper not taking the latest changes – what to do?


Sometime when you do the changes and run the application the latest changes are not updated while running the application.

The culprit is the system folder.

{user_home}\system11.1.1.4.37.57.75\o.j2ee\drs\

has the exploded war file which will have the classes that is old. deleting the classes from the exploded directory would definitely fix the issue.

system folder not getting deleted… uffff


I am fed of this Jdeveloper.. Its behaving weird sometimes and will no listen to what I say..

quite many of us would feel the same way and there is only one way to fix this..

Deleting the system folder… 🙂

this post will tell the exact location where you can find the system folder in windows..

One issue that we face is that how much ever you try to delete sometime you will get

so what’s the reason:

This issue is because of the limitation in windows machine that the maximum length of the folder hierarchy is 255 to 260.. not sure about that but its less than 260 characters.. [path+filename]

and to identify in our system folder.. the following path violates the above max limits.

C:\Documents and Settings\{user_id}\Application Data\JDeveloper\system11.1.1.4.37.59.23\DefaultDomain\servers\DefaultServer\tmp\_WL_user\oracle.webcenter.framework.view

(all folders [3 mostly] that starts with oracle.webcenter.framework under _WL_user)

workaround:

move all the three folders that starts with oracle.webcenter.framework to much higher level .. say.. outside the actual system folder itelf.. [C:\Documents and Settings\{user_id}\Application Data\JDeveloper\].. and delete it..

now your system folder will get deleted easily.. 🙂
