Embeding Unicode Font Causing Out of Memory

I am working on a project to generate pdf files in Chinese. It works fine 
when it runs stand alone. It causes a out of memory error when it is 
running on Tomcat 5.5. Here are some additional information:

Fop version:            0.94
Configuration File: 

<?xml version="1.0"?>
<fop version="1.0">
  <base>.</base>
  <source-resolution>72</source-resolution>
  <target-resolution>72</target-resolution>
  <default-page-settings height="11in" width="8.26in"/>
 
  <renderers>
    <renderer mime="application/pdf">
      <filterList>
        <value>flate</value>
      </filterList>

      <fonts>
        <font metrics-url="C:/arialuni.xml" embed-url=
"C:/windows/Fonts/arialuni.ttf" kerning="yes">
                <font-triplet name="arialuni" style="normal" weight=
"normal"/>
                <font-triplet name="arialuni" style="normal" weight="bold"
/>
                <font-triplet name="arialuni" style="italic" weight=
"normal"/>
                <font-triplet name="arialuni" style="italic" weight="bold"
/>
          </font> 
      </fonts>
    </renderer>
  </renderers>
</fop>

If I do not use configuration file, the applicaiton works fine except all 
Chinese characters are displayed as #. 

Could someone help me this out?

Thank you for your response. Actually I had tried to increase Tomcat's 
maximum heap size to 1024m. It does not help. You are right. It is a 
Tomcat's problem. I will seek help from Tomcat's mailing list.

I don't think it's a FOP problem. Try to increase heap memory of the 
virtual machine when you start your Tomcat. I think you can modify 
"catalina.sh"/"catalina.bat"

 Run "java -X" on commandline to see additional commandline parameters.
