Description:
A Technical Advisory has been issued to address problems starting the APM Web Start Workstation. The Advisory allows users to run the Web Start workstation with Java 7 u45, but does not work with Java 7 u51. This article updates the Advisory to allow users to run the Web Start workstation with the enhanced security present in Java 7 u51 and above by taking the additional step of reducing the Security Level from High to Medium.
Solution:
Java 7u51x64 is installed on the user's Workstation PC.
APM Web Start Workstation 9.5.1.0
Check the local Java version on the workstation PC with the command
java -version
Open an IE browser on the user's Workstation PC.
Enter the address of the EM Web Start in the browser:
http://***:8081/workstation
The Web Start workstation fails to launch.

Web Start fails to start with SecurityException.
Implement Technical Advisory Workaround Option 1 for Java 7u45 by making updates on EM-MOM.
Option 1. Update the file <EM_HOME>/product/enterprisemanager/plugins/com.wily.introscope.workstation.webstart_X .X.X/WebContent/jnlp/workstation.jsp with the following items. This workaround requires that the Security Level setting for Java in the Java Control Panel is set to a maximum of "High".
- Remove the following JNLP properties in the <resources> section
<property name="osgi.instance.area" value="@user.home/Application Data/Wily/Introscope/product/workstation"/> <property name="osgi.configuration.area" value="@user.home/Application Data/Wily/Introscope/product/workstation"/> <property name="eclipse.product" value="com.wily.introscope.workstation.productWebstart"/>
- Add the following arguments to the <application-desc main-class="org.eclipse.equinox.launcher.WebStartMain"> section
<argument>-product</argument> <argument>com.wily.introscope.workstation.productWebstart</argument> <argument>-data</argument> <argument>@user.home/Application Data/Wily/Introscope/product/workstation</argument> <argument>-dev</argument> <argument>@user.home/Application Data/Wily/Introscope/product/workstation</argument>
Web Start still fails to launch.
