Hi

java.lang.OutOfMemoryError means that your JVM is running out of heap space,
and
is such not a dbforms related error, but a java in general error. 

I believe the java maximum heap size by default equals 64MB, you can increase
this value by adding -Xmx<value>M on the command line, for example -Xmx128M
gives your JVM a maximum heap size of 128MB of memory.

The solution is to configure Tomcat to use a larger heap size. This can be done
by editing [TOMCAT_DIR]/bin/catalina.bat (MS Windows) or catalina.sh (Unix 
systems).
You can increase the heap size by adding a parameter to the environment variable
JAVA_OPTS. The parameter to be added is '-Xmx128M' (where the number 128 
indicates
that 128 Megabytes should be used. Increase as required).

For catalina.bat there now should be a line in your file that looks like this:
set JAVA_OPTS=-Xmx128M

For catalina.sh the line should look like this:
JAVA_OPTS='-Xmx128M'
