Problems with passing arguments to app

Question

Hi.
I have a litle problem with passing arguments. I create a dynamic jnlp file using jsp. This is my code:
<%
response.setContentType("application/x-java-jnlp-file");
String l = request.getParameter("login");
String p = request.getParameter("pass");
out.println("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
out.println("<jnlp spec=\"1.0+\" codebase=\"http://212.244.104.27:8080/PzP_INSTALL/\" href=\"pzp.jsp\">");
out.println("<information>");
out.println("<title>xxx</title>");
out.println("<vendor>xxxx</vendor>");
out.println("<homepage href=\"main.jsp\"/>");
out.println("<description>text</description>");
out.println("<offline-allowed/>");
out.println("</information>");
out.println("<security>");
out.println("<all-permissions/>");
out.println("</security>");
out.println("<resources>");
out.println("<j2se version=\"1.4+\"/>");
out.println("<jar href=\"jars/pzp.jar\" main=\"true\" download=\"eager\"/>");
out.println("<jar href=\"jars/config.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/commons-beanutils.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/commons-collections.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/commons-digester.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/commons-logging.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/commons-validator.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/easclient.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/easj2ee.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/jakarta-oro-2.0.7.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/jbcl.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/log4j-1.2.7.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/jdom.jar\" main=\"false\" download=\"eager\"/>");
out.println("<jar href=\"jars/xercesImpl.jar\" main=\"false\" download=\"eager\"/>");
out.println("<property name =\"javaws.login \"  " + "value=" + "\"" + l + "\"" + "/>");
out.println("<property name =\"javaws.pass \"  " + "value=" + "\"" + p + "\"" + "/>");
out.println("</resources>");
out.println("<application-desc main-class=\"aaa.bbb.ccc.MyClass\"/>");
out.println("</jnlp>");
%>My problem is when i have the href tag filled, the arguments that i passed equlas null, when i remove the href everything is ok besides that the app doesnt show in application manager and doesnt create an icon on the desktop.
out.println("<jnlp spec=\"1.0+\" codebase=\"http://62.89.104.27:8080/PzP_INSTALL/\" href=\"pzp.jsp\">");
Any help would be appreciated.

Hello again.
Thanks for your replay but unfortunetly it doesnt work too :-(
I've tried to use the out.println statemants in the servlet instead of using a jsp page but the error is the same. Please look at my code and tell me if you can what could be wrong.
This is the error message:
An error occurred while launching/running the application.
Title: PZP
Vendor: SPEED
Category: Download Error

This is the brief of code which starts the servlet
<form action="http://212.89.104.27:8080/PzP_INSTALL/servletpzp" method="post">
  <input type="hide" name="login" value=<%=l%>>
  <input type="hide" name="pass" value=<%=p%>>
  <input type=submit value=Start PZP>
</form>
This is the web.xml file code.
