Question

我在从Netbeans编译java文件时遇到java堆空间错误。

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
    at com.mysql.jdbc.Buffer.<init>(Buffer.java:59)
    at com.mysql.jdbc.MysqlIO.nextRow(MysqlIO.java:1975)
    at com.mysql.jdbc.MysqlIO.readSingleRowSet(MysqlIO.java:3437)
    at com.mysql.jdbc.MysqlIO.getResultSet(MysqlIO.java:488)
    at com.mysql.jdbc.MysqlIO.readResultsForQueryOrUpdate(MysqlIO.java:3131)
    at com.mysql.jdbc.MysqlIO.readAllResults(MysqlIO.java:2299)
    at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2722)
    at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2788)
    at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2738)
    at com.mysql.jdbc.StatementImpl.executeQuery(StatementImpl.java:1617)

我可以将opencv的VM选项设置为本机库，如下所示：

-Djava.library.path="C:\opencv\build\java\x86"

如何在VM选项中为java max heap size -Xmx2048m设置第二个选项？还是有另一种方法来增加netbeans中的Java堆大小？

如何在VM ptions -Netbeans-Windows中设置两个选项？
