JSP in NWDS

[Former Member]

hi

i want to do a JSP application in NWDS

but there is some problem occurring

i will just brief u with the steps i have performed first

Click File->New->Project.

Select Portal Application from left side select Create a Portal Applicatoin Project from the right side,

click Next.

Name you project.

Click Finish.

If not already in the java perspective, click the little icon on the toolbar on the left hand side which has a "J" in it.

You should see your project in the package explorer.

Open the tree structure, you should see src.api, other stuff and a folder called dist. Open dist.

You should see all kinds of folders.

See the portalapp.xml file, this will be important later.

Put you .JSP files in the Pagelet folder and your images under the images folder.

No go back to the top. Uner the src.api folder, create a package.

Right-click > New> Package, name it(com.yourcompany.test).

Now right click the package and create your classes.

Rightclick -> New --> Other, select Portal Application on left and "Create a new Portal Application Object on right.

Click next, hightlight your project,

click next.

Open the Portal Component Node, select JSPDynpage,

Click next, Name the files...select API for location and click Finish.

after doing all this i m getting 2 errors stating

1> This compilation unit indirectly references the missing type javax.servlet.http.HttpServletRequest

(typically some required class file is referencing a type outside the classpath)

2> The project was not built since its classpath is incomplete. Cannot find the class file for javax.servlet.http.HttpServletRequest. Fix the classpath then try rebuilding this project.

how can i rectify these errors

Hi John,

Try Add using External jars.

Ideally NWDS studio automatically adds these jars as a reference if the wizard is used.

Just a quick thought - have to tried to reorganize the imports?

Rightclick on the sourcecode and click on "Source" -> "Organize Imports"

This all doesnt help means you have to install NWDS again.

Hi John,

Your project can be deployed .As these are just warnings and pointing towards the htmlb jar that has been included but not used.you can just remove the import statement from your .java code.It will work fine.

Hi John,

You can add the jars by right clicking on the project name->properties->java build path->addd external jars->browse till

•\SAP\IDE\IDE70\eclipse\plugins\com.sap.tc.ap_2.0.0\comp\SAP_JTECHS\DCs\sap.com\com.sapportals.htmlb\_comp\gen\default\public\default\lib\java\htmlb

•\SAP\IDE\IDE70\eclipse\plugins\com.sap.ep.applicationDevelopment_7.00\com.sap.portal.htmlb_api

Add both the jars.

In the created JSPDynpage .java file you can add

import com.sapportals.portal.htmlb.page.JSPDynPage;

import com.sapportals.htmlb.page.DynPage;

import com.sapportals.portal.prt.runtime.PortalRuntime;

It should remove the error.

Hi,

Follow the suggestions here, to set classpath to the required jar files:

Use class locator to find which classes exist in which jar files:

Hi,

The classes reside in the servlet.jar. To be able to use the import, you should add this to your project's build path. You can use the predefined variable that comprises all J2EE standard libs - i.e. access the Properties of your project from the context menu, select Java Build Path -> select the Libraries tab -> press the Add Variable button. There should appear a variable called TSSAP_JAVAX_HOME. Select it, choose Extend button -> browse to lib/servlet.jar and add this to the list of referenced libraries.

This should work.
