Re: [rules-users] Entry point stream OutOfMemoryError?

Based upon what I understood from Drools fusion documentation, entry point stream can source data from file stream, so it could process data in GB’s. Believe me this is not what I found, to my surprise I found out I got – Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.GregorianCalendar.computeFields(* GregorianCalendar.java:2020*) at java.util.GregorianCalendar.computeFields(* GregorianCalendar.java:1996*) at java.util.Calendar.setTimeInMillis(*Calendar.java:1109*) at java.util.GregorianCalendar.<init>(*GregorianCalendar.java:576*) at java.util.Calendar.createCalendar(*Calendar.java:1011*) at java.util.Calendar.getInstance(*Calendar.java:948*) at CashFlowTest.main(*CashFlowTest.java:66*) I am reading a huge file in while loop, inside this loop object is being constructed and inserted into entry point stream. Before even rules would start firing, it goes straight into exception. Like below- *while* ((readLine = bufferedReader.readLine()) != *null*) { String transactionType = readLine.substring(13, 14); String amount = readLine.substring(9, 12); *if* ("C".equals(transactionType)) { CashFlow wCashFlow = *new* CashFlow(Calendar.* getInstance*() .getTime(), Double.*valueOf*(amount), *CREDIT*, 1); memoryEntryPoint.insert(wCashFlow); } *else* { CashFlow *wCashFlow* = *new* CashFlow(Calendar.* getInstance*() .getTime(), Double.*valueOf*(amount), *DEBIT*, 1); } } Unless I am doing something wrong here, I conclude it entry stream cannot source GB data? *From:* Aman [mailto:boy18nj@gmail.com] *Sent:* Sunday, October 03, 2010 10:06 PM *To:* 'Rules Users List' *Subject:* RE: [rules-users] WorkingMemoryEntryPoint NullpointerException?

Are you using that entry-point in your rules? That might be the problem. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
