Hi, I faced a typical issue while deploying the zul application in Weblogic 12c . with the following error

java.lang.IllegalStateException: strict servlet API: cannot call getOutputStream() after getWriter() at weblogic.servlet.internal.ServletResponseImpl.getOutputStream(ServletResponseImpl.java:297) at javax.servlet.ServletResponseWrapper.getOutputStream(ServletResponseWrapper.java:138) at javax.servlet.ServletResponseWrapper.getOutputStream(ServletResponseWrapper.java:138) at weblogic.servlet.internal.DelegateChunkWriter.write(DelegateChunkWriter.java:108) at weblogic.servlet.internal.ChunkOutputWrapper.write(ChunkOutputWrapper.java:148)

After searching for hours we were able to pin point the issue .

whenever our jsp page has jsp:include tag where we include the zul page it like <jsp:include page="/zul/Menu.zul"/> . Same scenario also occurs when we try to include the Menu.zul in apache tiles .

Any Ideas on this ?? Urgently require help.

My Menu.zul looks like this.

<?page title="" contentType="text/html;charset=UTF-8"?>
<zk>
    <window id="mainmenubar" apply="org.zkoss.bind.BindComposer"
        border="none"
        viewModel="@id('vm') @init('com.***.cdars.web.vo.MenuBarVM')">
        <menubar id="mbar"
            autodrop="true"
            children="@bind(vm.nodes) @template(empty each.children?'menuitem':'menu')">
            <template name="menu" var="menu">
                <menu label="@bind(menu.name)">
                    <menupopup sclass="mymenupopup"
                        children="@bind(menu.children) @template(empty each.children?'menuitem':'menu')" />
                </menu>
            </template>
            <template name="menuitem" var="item">
                <menuitem label="@bind(item.name)"
                    onClick="@command('menuClicked',menuitem=item)" />
            </template>
        </menubar>
    </window>
</zk>

The problem got solved when i used c:import tag for including zul pages in jsp . Instead of just doing it through jsp:include . The issue is weblogic obeys strict servlet api.
