IE7 converted applet problem

We have the following code which works in IE6 and IE7. We used the Sun HTML converter to use the java plug-in (shown below) which also works in IE6. However, the converted code below does not work in IE7. Need to use the converted code so any help on why it is not working would be greatly appreciated.

<APPLET CODE = "com.thebrain.teambrain.applet.TeamBrainApplet.class" JAVA_CODEBASE = "<%=base%>" ARCHIVE = "client.jar" WIDTH = "100%" HEIGHT = "100%" NAME = "tbApplet">
<PARAM NAME = "BASE_URL" VALUE ="<%=baseurl%>">
<PARAM NAME = "KNOWLEDGE" VALUE ="<%=baseurl%>/ControllerServlet">
<PARAM NAME = "CONSTRAINTS_URL" VALUE ="<%=baseurl%>/ConstraintServlet">
<PARAM NAME = "scriptable" VALUE="true">
<PARAM NAME = "CONTENT_ADAPTER_TARGET" VALUE ="tbmiddleframe">
<PARAM NAME = "ABC" VALUE ="<%=securityMode%>">
<PARAM NAME = "USER_TYPE" VALUE ="<%=userType%>">
<PARAM NAME = "USER_ID" VALUE ="<%=userid%>">
<PARAM NAME = "isSSL" VALUE ="<%=isSecure%>">
<PARAM NAME = "<%=noStartId%>START_ID_FROM_URL" VALUE = "<%=startId%>">
