Problem when generating report dynamically

Gustavo.Av

Hello all <br />
I have a web application developed in PHP and integrated with birt by PhpJavaBridge. My birt version is 2.6.2. I have an class in java wich i use like an factory to build report itens as php request them. <br />
The report itens are built fine, i can see them in the report design, test connection success, preview datasets ..... verything looks like ok. But when i run the report it gives me the error<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>java.lang.ClassCastException: java.lang.OutOfMemoryError cannot be cast to java.lang.Exception</pre>
<br />
The most weird thing is that if i change anything in the report, even add 1 letter to report title and run it again without changing anything in the design elements, it runs fine.<br />
<br />
Can someone help ?

In Tomcat it throws me the following stack trace:<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>Exception in thread "http-apr-9191-exec-5" java.lang.OutOfMemoryError: Java heap
