我们正在将 Oracle Forms 10g 应用程序迁移到 APEX 4.1 。
我们需要在APEX中加入一些表格。
我们有一个从APEX区域调用的PL / SQL函数call_form
(见下文),它只是编写applet来加载表单,并将表单名称作为参数传递。
它有效,但它总是重新加载表单服务,每次都需要 10s ,每次都会出现Oracle Application Server Forms Services徽标:
这对用户来说确实很痛苦......
我认为这是因为它每次都在重新加载jar文件,因此我在编写applet时尝试使用缓存选项( cache_option , cache_archive < / em>,...)将文件缓存在 JVM 中,但没有成功。
我每次都没有得到小程序安全警告,在 java缓存查看器中我可以看到4个jar文件 frmall.jar , frmwebutil.jar , FDialogPJC.jar 和 jacob.jar 。
以下是Java控制台的内容,在调用表单,然后重新加载页面时,它似乎加载 webutil 2次:
RegisterWebUtil - Loading WebUtil Version 10.1.2.3
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.3
RegisterWebUtil - Loading WebUtil Version 10.1.2.3
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.3
我的JVM是1.6.0_31 。
call_form
程序:
procedure call_form(in_form_name in varchar2) is
begin

您对我如何阻止有任何想法?或者您认为有更好的方法将Oracle Forms包含在APEX中吗?
非常感谢任何帮助。
感谢。
