Re: AWT and Servlet Exception

Pete

Do you have "OS/400 - Portable App Solutions Environment" installed on your system? I think I recall that headless awt requires PASE.

Thanx, PLA

I haven't gotten a response on the JAVA400 list and perhaps this is the
better list anyway....

I have a servlet running under Tomcat 5.0 on our V5R3M0 iSeries that throws
a javax.servlet.ServletException: "AWT class or API used without specifying
property os400.awt.native=true or java.awt.headless=true" exception when
generating a Jasper report. 

The Java400 list had a dead on hit on the error but it had a bit of missing
information, namely how the properties were set so that
os400.awt.native=true or java.awt.headless=true properties could be seen by
Tomcat.

I added two entries to /QIBM/UserData/Java400/SystemDefault.properties file
java.version=1.4 java.awt.headless=true

I ended Tomcat on the iSeries and then restarted it and accessed the
application again with the same result. 

I probably missed something simple here but, what did I miss?

Now I am also seeing two errors in the job log of the Tomcat instance:

The requested heap space operation is invalid. (MCH6902) The pointer parameter passed to free or realloc is not valid.(C2M1212)


The servlet is still running but when I execute the jasper report I get the
servlet exception (listed above).

Any help would be appreciated.

Thanks,
