  • 1.  Turning tracing off

    Posted 12/11/01 02:06 AM

    Hi,

    I’m trying to call the API from an applet, and am getting this error (since applets are not allowed to read system properties)

    Any suggestions?

    log4j: Could not read system property “log4j.configDebug”.

    ess denied (java.util.PropertyPermission log4j.configuration read)

    You can use

    code:

    import com.softwareag.tamino.db.API.common.TTrace;
    …
    TTrace.setActiveTrace(false);

    to turn off tracing, but I found that whether I set tracing to false or true like this, I got your problem. If I removed all references to TTrace from my code I didn’t get your problem, but I got a new one when I tried to create a new TConnection:
    com.ms.security.SecurityExceptionEx[com/softwareag/tamino/db/API/common/TPreference.get]: Unable to access system property: com.softwareag.tamino.db.API.invocation.invocationModifier
    at com/ms/security/permissions/PropertyPermission.check (PropertyPermission.java)

    So it looks as if you need to sign your applet to make it trusted (or use a servlet instead).

    quote:

    Sorry, our used logging tool doesn't care about an applet context. So there is only the way to change the java.policy file in case of using a browser or to give your own policy file to the appletviewer. We will change this behaviour in the next version.
