Hello all
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.
My JAVA_OPTS was set like in my catalina.bat:

set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx1024m -XX:MaxPermSize=512m -Djava.awt.headless=true

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
in eclipse
java.lang.ClassCastException: java.lang.OutOfMemoryError cannot be cast to java.lang.Exception

in tomcat
Exception in thread "http-apr-9191-exec-5" java.lang.OutOfMemoryError: Java heap

Can you post your code? Verify that all tasks get closed and that the engine only gets started once for the life of the application,

Jason

so from php i call each element i wanna build according to my request, after my builder returns the build up java class to my php i add it using the "addToDesign" method, to the design body . It can be a text item and after it 2 tables each one with different data and different report itens and after more 2 text itens elements (my testing example).

Are you only calling this:
Platform.startup( designConfig );
once?

I have my initReport called in my php class construct method and the same class has a singleton() method to prevent more instances of it.
after i build my report i call the closeReport method wich contains the Platform.shutdown()

Jason i run up some tests here and i found that when i have more then 1 element bound to the same dataset the outOfMemory error occurs, but if i have each element bound to distinct datasets it renders without any errors.

Can you do a reportDesign.saveAs and post the report when you more than one element bound to a dataset?

So in the report you posted, the first and last text item are bound to the same dataset. If you remove one of these the issue goes away?
I no data set caching was improved in 3.7, but these should be caching. One thing to try is to add a grid that contains the first text item, the table and then the last text item. Remove the binding setting for the text items and set it once on the grid. One another note, why in the following code are you setting the dataset on data items instead of setting on the container element?

public DataItemHandle createDataItem(String name, String expression, DataSetHandle dataSet, String resultSetCol,
ArrayList<String>columnBindings, HashMap<String, String> properties) {
System.out.print(".....Creating data item: \""+name+"\"");

DataItemHandle data = designFactory.newDataItem( "data_"+name );
try {
data.setStyleName( DefaultDetailStyle );
if(dataSet != null) {
data.setDataSet( dataSet );
data.setResultSetColumn( resultSetCol );
}

Because i can have a data item with different dataset binding, i already changed these lines to
if(dataSet != null) {
data.setDataSet( dataSet );
if(resultSetCol != null) {
data.setResultSetColumn( resultSetCol );


so when i create a table i dont inform dataItem's data set, just the resultsetcol and bind the dataset to the table. Only if the dataset parameter is set that it will bind it to the data item instead of the container.

Anyway, just tested creating textItens inside a grid with just 1 cell and bound the datasets to the grids instead of the text items. The outOfMemory error still occurs.

I cant do the grid thing because as this is a dynamic proccess there are cases in what ill have n elements bound to n datasets, i mean in this example i had 2 text item to same dataset and 1 table to another, but what if i had 2 text in dataset 1, 2 table in dataset 2, more 2 texts in dataset 3 and 3 tables in dataset 4, if i follow ur container idea i will have to create a grid for almost each design element.

I just created another environment to test this with birt 3.7.2.
In tomcat cleared my javabridge platform folder, copied the lib from 3.7.2 runtime to javabridge lib and also updated the viewer.
First time i run the report is built fine but the outOfMemory error still happens, but second time it start giving me this error
org.eclipse.birt.core.exception.BirtException: error.CannotStartupOSGIPlatform
        at org.eclipse.birt.core.framework.Platform.startup(Platform.java:81)

i checked migration changes and all i did was add runtime lib to my project buildpath and removed the following line from source

That error looks like you are starting and stopping the platform many times. Are you sure that you are not?
Take a look at this bugzilla entry for restarting the platform:

Jason i tested again adding the RegistryProviderFactory.releaseDefault(); after Platform.shutdown(). This managed the osgi startup error, but the outOfMemory error still persists.

Did you figure out if the platform is constantly re-started. If you fix this it may fix your out of memory error.

Jason, i limited the platform lifecycle to user's session in php, before was limited per build request. Now the platform is started during user session, the build became faster but unfortunatelly it still giving me the error
The test was made with platform started, i build up the report and test it without shutting down the platform(because if i do it ill need to restart it again in the next request so i would be back to the same place i was) and when the user ends his session the platform is then shutted down.

There is another weird stuff in birt 3.7.2 generated report... when i render it in preview its ok but if i see it in any webviewer (from Eclipse birt 3.7.2 RCP viewer and tomcat viewer) the last text item is duplicated several times.

Have you logged a bugzilla entry for this? If you want I can do a skype session to have a look at it.

Do you want to log both problems or just the dataset cache ?
Can you send me the link to birt bugzilla entries ?
Thanks.
