Hi All,
I am trying to use Google Data API library on App cloud. When trying
to invoke the API, I am getting the following runtime permission
error.
java.security.AccessControlException: access denied
("java.net.NetPermission" "getCookieHandler")
java.security.AccessControlContext.checkPermission(AccessControlContext.java:372)

org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java:166)
As mentioned in Google App Engine Q&A [1] the work around is to add the
following to the appengine-web.xml.
<system-properties>
<property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>
Therefore, I tried to add followings into my web.xml.
<env-entry>
<env-entry-name>com.google.gdata.DisableCookieHandler</env-entry-name>
<env-entry-type>java.lang.Boolean</env-entry-type>
<env-entry-value>true</env-entry-value>
</env-entry>
I also tried `env-entry-type` as `java.lang.String` and all workarounds in
[2], still getting the same error.
1. Any solution to get rid of this error?
2. How can I change these security policy configurations on the App Cloud?
