Debugging JSPs using Visual Cafe

          I am using WL 5.1 and trying to figure out how to debug JSPs using Visual Cafe 4.0.(Enterprise Edition). The JSP file is running fine if I use plain "javac" for compilation. If I change the compiler to include -g option (for debug), I get the following error.

assuming you are running on Windows, you can use a .cmd file with the
          following command in it
          javac -g %*
          if you name it c:/java/bin/javac.cmd, then replace the line with
          compileCommand=C:/java/bin/javac.cmd,\

Remote debugging JSPs using Forte and Weblogic

I am compiling JSPs using a build script (ANT) and deploying it to weblogic server instance running on unix. when i mount the JSPs and my classes to Forte and connect to weblogic instance, I can debug the java files. But the JSPs i can't debug. I can put the break points in JSPs but the debugger is not stopping at that breakpoint when i run my application in the browser.

I guess I can answer the question myself...
Turns out that there was a problem in 1.3.0. BugParade #4342974.

Debugging JSP with standalone OC4J

Hi All,
I am trying to debug a JSP using JDeveloper 10.1.3.2 on standalone OC4J 10.1.3.2 . I find that it is not stopping at the breakpoints I have set. My settings in the global-web-application.xml are as follows
<servlet>
<servlet-name>JDevOJSP</servlet-name>
<servlet-class>oracle.jsp.runtimev2.JspServlet</servlet-class>
<init-param>
     <param-name>check_page_scope</param-name>
     <param-value>true</param-value>
</init-param>
<init-param>
     <param-name>debug_mode</param-name>
     <param-value>true</param-value>
</init-param>
<init-param>
     <param-name>developer_mode</param-name>
     <param-value>true</param-value>
</init-param>
<init-param>
     <param-name>encode_to_java</param-name>
     <param-value>true</param-value>
</init-param>
<init-param>
     <param-name>emit_debuginfo</param-name>
     <param-value>true</param-value>
</init-param>
<init-param>
     <param-name>jspjavacompiler</param-name>
     <param-value>oracle.jdevimpl.jsp.JspOjcCompiler</param-value>
</init-param>
<init-param>
     <param-name>jspcompiler</param-name>
     <param-value>oracle.jdevimpl.jsp.JspOjcCompiler</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
However when I try accessing the JSP(test.jsp) from the browser, I get an error saying _test.class is not found.
I verified this by checking under the application-deployments folder and I found that the .java & .class files are not created under the persistence\_pages folder.
So I changed the entry in global-web-application.xml as follows to get the .java & .class files generated
<servlet>
     <servlet-name>JDevOJSP</servlet-name>
     <servlet-class>oracle.jsp.runtimev2.JspServlet</servlet-class>
</servlet>
Once they are generated, I reverted the setting back to as it was before and tried to debug the JSP. But still it does not find the break points
I have jdev-rt.jar,xmlparserv2.jar,ojc.jar & jdev-remote.jar in <OC4J_HOME>/lib folder.
I am starting OC4J with OJVM option debug mode listening to port 4000 and I have configured my project in JDeveloper for remote debugging.Please let me know where I am going wrong.
Thanks in advance,
Prasanna

How to debug jsp program

Thanks,
I havenot used Oracle before I know that
you could debug JSP in Visual Age for Java,
but where could we debug jsp code,
thanks,
null

You can debug JSPs and Servlets in JDeveloper locally in the IDE itself, or remotely.
To debug locally within JDeveloper, simply place breakpoints anywhere in the source code and choose Run | Debug from the main menu. The JSP is run using Oracle's Web-to-Go server.
Remote debugging requires a little more setup. See the online help for more information.

Debug JSP/JDeveloper 3.1

I am trying to use JDeveloper 3.0 to debug JSP pages. The pages call each other through standard link tags ( <a href=myjsp.jsp...)
I can debug a single jsp page but not the linked to pages. Can this be done in 3.0?
If not.. when is JDeveloper 3.1 expected??
Thanks,
Dave
null

This is possible in JDeveloper 3.0
For example create
A.jsp which has a link to B.jsp as
<P><% out.println("Hello World"); %></P>
Call second JSP
Place a break point on out.println
B.jsp has
<P><% out.println("Hello World"); %></P>
place a breakpoint on this line
Run A.jsp in the debug mode and when you see the html page rendered in browser click on the link which calls B.jsp and this will stop at the breakpoint place in B.jsp

Can I debug jsp in eclipse ?

I am using wtp eclipse and I want to debug jsp please guide me how to ?

Yes, just the same way as you do with normal Java classes. Run the server in debug modus and put breakpoints in the source file.
But do you have business logic (scriptlets?) in your JSP then? I'd to put them in separate Java classes (Servlet, Bean, DAO, Utility, etc). It will greatly ease unit testing and debugging (and also maintenance!).

Debug JSP file

Hi,
Is there any tool to debug the JSP files? I want to debug my JSP how to do it? Please clarify.
Thanks.

Yes, 30$ or thereabouts. I do not have to pay for it though ;)
I wouldn't pay for a tool just to be able to debug JSPs though ;) I'll just work with System.out or a logger to trace where stuff goes wrong.We used to do that before we convinced the management that we work for that it really saves huge time (money and productivity)
Its a life saver for us :). The jsps are sometimes 500 lines long (no dont kill me, I did not write those. Just have to maintain them :( ) and I shudder to think of those dark days where we kept adding incremental sysouts, then do a build and watch the stack trace. Sometimes the server did not pick up the jsp changes and a restart was needed ( more shudder :) )

Edit: Just wanted to add that it needs some setup and is not for the faint hearted

I never really had much luck with this approach.
Mind you I was using Crystal Reports 10, and as far as I recall it didn't allow setting/changing of database at this level.
Things to check
- can you create a database connection on your page with this URL/username/password?
- what server are you using? Tomcat? WebLogic?
I found this in your other post:
Connection Information: {Server Name=ee6rpt, Connection String=DSN=s(ee6rpt);User ID=s(ee62test);Password=;UseDSNProperties=b(false), Database Name=, Database DLL=crdb_odbc.dll}That would indicate it is using odbc to connect to the database (crdb_odbc.dll). ODBC is a bad idea with java.
The way I have got it to work for me (after much trial and error) was to in Crystal Reports to connect using the Oracle Driver, and specifying a tnsname - eg define REPORT_DS in tnsnames.ora.
When running through the JRC, it looked for a JNDI datasource under that same name "REPORT_DS".
Don't know if that will help you or not.
Good luck,

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

How to display the data in XML files into JSP using Jdeveloper.

Hi All,
I have two XML files one XML file has the view names and the other has the table names of a particular views, how to display the data in JSP using JDeveloper where when i click a particular view the list of tables of that particular view from XML file two should be displayed in JSP Page.
Are there any reference documents, regarding the above process please can anyone guide through how to do it.

Let the servlet ask your business tier to provide the data, then stuff it into beans, and pack those into the Session instance. Then forward the request to the JSP, let the JSP get those beans and display them.

Display PDF in JSP using a content selector

Hello,
We are running on WLP 8.1 sp4. We have documents (Word and PDF) stored in the Weblogic Portal content management system. We have made several tries, but are unsuccessful in rendering a PDF inside a JSP using Content Selector tags. We can get a link to display and other properties of the content type, but we have not been able to show the actual binary property of the PDF. Has anyone climbed this mountain before, any help will be greatly appreciated!
Rob
The following displays links to the documents, but not the actual document.
<pz:contentSelector rule="novel_flu_db_archived_reports"
id="fluArchiveQuery" />
<utility:notNull item="<%=fluArchiveQuery%>">
<utility:forEachInArray array="<%=fluArchiveQuery%>" id="docA" >
<cm:getProperty id="docA" name="file" conversionType="html" />
<ad:render id="docA" />
</utility:forEachInArray>
</utility:notNull>

Thank you for the response.
Option 1 - would be great, but I am having problems getting this to work (see thread "Problem accessing a file stored in the CMS from link on JSP")
Option 2 - I need to look into, as we need to be compliant with Accessibility standards and I can't remember if IFrames pose any problems for screen readers.
Option 3 - introduces an additional step to the work flow, we would like to avoid extra work (if possible)
In looking through the archives, there was mention of a "stand alone" JSP which was not under a Portlet or the Portal. The PDF was displayed in the stand alone JSP where the mime type was altered to PDF. Would this be an option?
