If you happen to get the JDBC Connection error when you run the Application Module then make sure to check the adf-config.xml property jbo.SQLBuilder which should point to the correct database.

JPS-01520: Cannot initialize identity store

oracle.security.jps.service.idstore.IdentityStoreException: JPS-01520: Cannot initialize identity store.

<IdentityStoreUtil> <getIdentityStoreFactory> Cannot initialize identity store.
<PageUtils> <getUserName> Failed to get user name

If you happen to get the error while running the weblogic server then the possible cause can be to add the entry in config.xml (\Users\username\AppData\JDeveloper\system11.1.1.5.37.60.13\DefaultDomain\config\config.xml)

<listen-address>localhost</listen-address>

that is the localhost is missing.

Referring custom libraries in jdev 10.1.3.4

Leave a reply

I recently happened to work on jdeveloper 10.1.3.4 and was given a task of bringing up the server. The project was using the custom libraries which the embedded oc4j was complaining that it could not find saying

Caused by: oracle.oc4j.sql.config.DataSourceConfigException: Unable to create : com.ibm.as400.access.AS400JDBCDriver
at oracle.oc4j.sql.config.DataSourceConfigUtils.createConnectionFactory(DataSourceConfigUtils.java:283)
at oracle.oc4j.sql.DataSourceConnectionPoolImpl.<init>(DataSourceConnectionPoolImpl.java:108)
at oracle.oc4j.sql.spi.ResourceAdapterImpl.createDataSourceConnectionPool(ResourceAdapterImpl.java:99)
… 13 more

This was very challenging for me because this is the first time I ran an ADF application on Jdeveloper 10g. I searched on the forum with this error and could easily find that the fix is to copy the library to

..\jdevstudio10134\j2ee\home\applib

This is just for information as this could be helpful for newbie who is still working with Jdeveloper 10g

oracle.jbo.InvalidObjNameException: JBO-25005

Leave a reply

oracle.jbo.InvalidObjNameException: JBO-25005: Object name oracle_jbo_uicli_binding_JUIteratorBinding_281 of type Iterator Binding Definition is invalid.

the issue is with the filter order in the web.xml as explained in the bug 9880967

the correct order of the JspFilter and ApplSessionFilter in the web.xml is as follows

 <filter-mapping>
 <filter-name>JpsFilter</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 <dispatcher>FORWARD</dispatcher>
 <dispatcher>REQUEST</dispatcher>
 <dispatcher>INCLUDE</dispatcher>
 </filter-mapping>
 <filter-mapping>
 <filter-name>ApplSessionFilter</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 <dispatcher>FORWARD</dispatcher>
 <dispatcher>REQUEST</dispatcher>
 </filter-mapping>
