Encode URL with <h:outputLink> in WSRP Portlets
|
|
|
| Hi All,
Our project uses WSRP Portlets for development.
At a plain jsf level this does not pose a problem at all for me.
But in our project we use WSRP Portlets.Which has a producer and consumer framework.
Its a very simple requirement there is a pdf icon onclick of that i need to download the report from the database.
I used <h:outputLink> in the following manner to hit the download servlet.
But i need to encode the URL we do in our javascript.
String encodedURL_dtd = response.encodeURL(request.getContextPath()+ "/DownloadServlet");
<h:datatable var="item" value="databean.list" >
...............
<h:outputLink rendered="#{(item.strreportFormat == 'P') value="#{facesContext.externalContext.requestContextPath}/DownloadServlet">
<h:graphicImage value="/images/icon/icon_small_pdf.gif" alt="View Reports"></h:graphicImage>
<f:param id="id1" value="item.id" />
<f:param id="sys1" value="item.sysName" />
</h:outputLink>
.......
</h:datatable>
Any suggestions are welcome....

| You can use the same EL expression in the JS code if it's in the tag's attribute.

| I hope i understood you correctly but i tried to do something like this and it gave me the following error.
JSPG0124E: Custom tag attribute value cannot be runtime expression. value: "[%= renderResponse.encodeURL(renderRequest.getContextPath() + "/ReconProcessorServlet") %]"
When i tried replacing this.
value="#{facesContext.externalContext.requestContextPath}/ReconProcessorServlet"> with
value="<%= renderResponse.encodeURL(renderRequest.getContextPath() + "/ReconProcessorServlet") %>" >
I couldn't find any corresponding EL for renderResponse.encodeURL.

| You can't use JSP expressions, only EL expressions on JSF tags, so <%= isn't goping to work.
Maybe I didn't quite understand what you are trying to do. You mentioned JavaScript, so I thought you were trying to move the same EL expression you had for 'value' into some JavaScript code.
If you are just trying to replace the expression for value, then what you can do is use a method of a managed bean (pagecode bean, for example) that does what you need and use that method for the expression on the value attribute.
For example:
value="#{pc_MyPage.servletUrl}"
and
public String getServletUrl() {
return ((RenderRequest)getFacesContext().getExternalContext().getRequest()).encodeURL(... and so on
}
