describes various techniques in getting the Java source generated for the
JSP file. |

Resolving the
problem |
Depending on where you are in the J2EE Application Life
Cycle, you can do this using various methods. In the cases below, the
generated Java source for all newly compiled JSP files will be stored in
the JSP scratch directory, which by default is the
WebSphere_Home/temp folder.
For more information, search for keepgenerated in the appropriate
version of the WebSphere®
Application Server Information Center.
- If you are in development phase and using tools like WebSphere
Studio Application Developer or Rational® Application Developer:
- Open the deployment descriptor for the WebApplication.
- Go to Extensions tab.
- Add a new jsp attribute with
name="keepgenerated" and
value="true".
- Save all changes.
- If you have already deployed your application and are using
JSPBatchCompiler to compile JSPs, then you can specify the keep generated
option for the JSP batch compiler:
JspBatchCompiler -enterpriseapp.name
enterprise_app_name -webmodule.name
web_module_name -cell.name
cell_name -node.name
node_name -server.name
server_name [-filename
jsp_name] -keepgenerated true
- If the application is already deployed and you do not want to use the
JSP Batch compiler, you can modify the configuration file to do the same
as in step 1, above:
- Edit the ibm-web-ext.xmi located in WEB-INF file for
the installed Web application.
- Edit file in
WebSphere_Home/config folder
- Do NOT edit the file in
WebSphere_Home/InstalledApps.
- Add the line as shown below, indicated by bold and underline, after
the webApp element in the same file:
<webappext:WebAppExtension xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:webappext="webappext.xmi"
xmlns:webapplication="webapplication.xmi"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmi:id="WebAppExtension_1"
reloadInterval="3"
reloadingEnabled="true"
additionalClassPath=""
fileServingEnabled="true"
directoryBrowsingEnabled="false"
serveServletsByClassnameEnabled="true">
<webApp href="WEB-INF/web.xml#WebApp"/>
<jspAttributes xmi:id="JSPAttribute_1"
name="keepgenerated"
value="true"/>
</webappext:WebAppExtension>
