heap space in jpa application

[Imen Jbebli]

Hi,

It’s the first time I work with netbeans.

I used to work with eclipse. I have done with it many web projects (using the frameworks STRUTS, HIBERNATE, SPRING and APACHE as web container).

Now we choose Netbeans, because as shown in this sample, NETBEANS generates all in some clicks and in a short time.

So, I applied the tutorial "http://www.netbeans.org/kb/docs/web/jsf-jpa-crud-wizard.html" with a database containing a lot of data (in some tables 2 millions of registrations), and the response time is too long and in the end a have a message (java heap space).

In fact, I encountered this problem with a project done with eclipse (web application with frameworks STRUTS, HIBERNATE and STRUTS) and I resolved it by adding “lazy="true"” for each tag “set” in the *.hbm.xml files, also I added the DLL “tcnative-1.dll” in order to perform APACHE TOMCAT, and so I no longer have the problems.

So, in this case, I tried to do the same think. So, I have deleted under the package “jpa.entities”, all the annotation “// @OneToMany(mappedBy = "idAbonnement")” and of corse the related attribute and the methods getter and setter, then I generated the JSF Pagesfiles from Entities Classes, but I always have the same problem ???????????????

I focused in your FAQ, I found you speaking about modifying /
*** netbeans_default_options="-J-Xms512m -J-Xmx512m -J-XX:PermSize=32m -J-XX:MaxPermSize=128m -J-Xverify:none
*** <java-config suffix="...">
<jvm-options>-Xmx512m</jvm-options>
<jvm-options>-XX:NewRatio=2</jvm-options>
<jvm-options>-XX:MaxPermSize=128m</jvm-options>
...
</java-config>
But no result.

My database is created under the SGBD PostgreSQL.
RAM: 1G
Procesess: 3.20 GHZ and P IV
Space in disque / 25 GO

I hope that you can help and advise me.

Thanks in advance
