Hello,

I am developing 1 web application for which I need to call some functions in .java file from .jsp file. I tried <%@page import="mypackage.myclass" %> but its saying ClassNotFound Exception.

Some details of application are:
I am using Weblogic 9.2.

I am deploying myjsp.jsp in \bea\weblogic92\samples\server\examples\build\mainWebApp\Trial\myjsp.jsp

.java file in

\bea\weblogic92\samples\server\examples\build\mainWebApp\Trial\mypackage

compiling this file as package (i.e. using javac -d ).
While compiling I am giving .class file to be generated in \bea\weblogic92\samples\server\examples\build\mainWebApp\WEB-INF\classes\mypackage\

Is this approch correct? as I am getting:

Error 500--Internal Server Error

java.lang.NoClassDefFoundError: mypackage/myclass

Please help me as soon as poosible.

Thanks.

Hello All,

I am developing an application in which I am sending a ResultSet from servlet to jsp page. ResultSet contains result of "select" query and I wanted to dispaly the output of this query in jsp page in table format.
In servlet the output of query is stored in ArrayList and I am sending this ArrayList using <jsp:forward page > tag.
In my jsp page I am getting ResultSet result using request.getParameter("param1").
Now I wanted to convert this request.getParameter("param1") to ArrayList and get its Attribute.
Can Anybody tell me how to achieve this?

Code for reference:


Servlet code: <% ArrayList results = new ArrayList(); while (rs.next()) { HashMap row = new HashMap(); results.add(row); for(int i=1; i<=columns; i++) { row.put(md.getColumnName(i),rs.getObject(i)); } }%> <jsp:forward page="viewjob.jsp"> <jsp:param name="param1" value="<%=results%>"/> </jsp:forward>


when I am printing values in JSP page using out.println(request.getParameter("param1")); are

[{STATUS=open, FUNCTIONAL_AREA=IT-Software, COMPANYNAME=TCS, JOBLOC=Pune, SALARY=5000, CONTACT_NO=1238, EMAIL=n@tcs.com, WORK_EXP=4, SKILL_SET=Java, COMPANYLOC=Pune}, {STATUS=Open, FUNCTIONAL_AREA=IT Software, COMPANYNAME=tcs, JOBLOC=pune, SALARY=4000, CONTACT_NO=12345, EMAIL=np@gmail.com, WORK_EXP=7, SKILL_SET=Java,J2EE, COMPANYLOC=pune}, {STATUS=open, FUNCTIONAL_AREA=IT-Software, COMPANYNAME=TCS, JOBLOC=Pune, SALARY=5000, CONTACT_NO=1238, EMAIL=p@tcs.com, WORK_EXP=4, SKILL_SET=Java, COMPANYLOC=Pune}]

Can anybody tell me How to extract values from this output and show it in table format?

Hey Jan,

Here are answers:

do you connect to the same database with 'JDBC' and with 'database directly'?

Yes

do you use the same user in both situations?
Yes
- can you show us the exact query you used in 'database directly'?
select * from userinfo where email='nehad@gmail.com'
- can you output the value of strQuery , and show it to us?
select * from userinfo where email='nehad@gmail.com'
- can you run this query from your code and see if that gives the same error (without the where clause ): "select * from userinfo"
I tried with select * from userinfo but same error

PS: I wrote another select query for same application but in other java file for same database as follows. This code is working fine.
Statement st=con.createStatement(); String strQuery = "select username,pasword from userlog"; System.out.println(strQuery); ResultSet rs=st.executeQuery(strQuery );

Hello,

I am developing one project in which I need to connect to Oracle 10g thr JDBC.
And then querying the database through java code.
My java code for executing select query is:
Statement st = con.createStatement(); String strQuery=null; strQuery = "select * from userinfo where email='"+email+"'"; rs1 = st.executeQuery(strQuery);

but I am getting following error.
PS: When I tried to fire this query in database directly its giving me proper reslut.

Can anybody please help me to solve this problem.

I need to download latest version of bea weblogic. can anybody tell me from which site can I download the same for free of cost ASAP.

Thanks Jan for your reply.
I really appreciate your concern.
I post this message because I was not able to think how to design.

I hope you understand my situation.
Once again Thanks for your concern.
