First JSP in WebLogic

Can anyone answer basic troubleshooting WebLogic question?
          My simple.jsp fails. Server creates _simple.java file, but no
          _simple.class throwing the following:
          java.lang.NumberFormatException: error=2 at
          java.lang.Integer.parseInt(Integer.java:409)
          at java.lang.Integer.parseInt(Integer.java:458)

          Code)

          at weblogic.kernel.ExecuteThread.run(ExecuteThread.java, Compiled Code)
          Perhaps it happens on the way of compiling it. Why NumberFormat though?
          But I was able to manually compile
          _simple.java and then page
          worked. Can you suggest anything?

send ur simple jsp code and also check that u have made the proper setting
          in the property files,
          i.e. the path of javac is right ,also the path of the directory where ur
          jsp's are translated in servlets is not in the weblogic classpath.
          Hope this helps
          Bye

Problem JSP and WebLogic 5.1

Hi!!!
I have a problem that I�m trying to show some results of a table of a DB with a JSP...but I don�t obtain nothing like result,....I don�t know why...I would hope to see the information of my table, like a select of SQL.
My code is:
<%
Connection conn = null;
try {
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:weblogic:pool:Mypool");
catch (Exception e) {
e.printStackTrace();
Statement stmt = conn.createStatement();
stmt.execute("select * from cat_employee");
ResultSet rs = stmt.getResultSet();
while (rs.next()) {
System.out.println(rs.getInt("key_1") + " - " + rs.getInt("key_2") + " - " + rs.getString("employee"));
stmt.close();
conn.close();
%>
Where cat_employee is the table name,
key_1, key_2 are fields of cat_employee table, of type numeric
employee is a field of cat_employee table, of type String
I think that with getInt() method, I obtain a number and with getString() method, I obtain a string....but I haven�t the complete API documentation, only the following API link:
http://www.weblogic.com/docs51/classdocs/javadocs/index.html
And the information about getString() ang getInt() is very incomplete there, if somebody have information about a API complete I would be very thankful with you. I�m using weblogic 5.1 in my development enviroment.
Thank you....

Hi!!!
(Your email direction doesn�t correct.....because my mail was returned to me....could you answer me to the following email: [email protected] please)
Thank you to answer me......I was really worried.....because nobady had done that.....
My problem is that I wish to do some queries to a table of a Municipalities DB, I have read about that....and according with the exemples....my JSP...should be running and executing very well....but I haven�t had success with that...:(
My JSP file is:
<!doctype html public "-//w3c//dtd html 3.2//en">
<html>

<head>
<title>Query of Municipalities</title>
</head>
<body bgcolor=#FFFFFF>
<font face="Helvetica">

</font>

Connection conn = null;
try {
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:weblogic:pool:DESAPool");
catch (Exception e) {
e.printStackTrace();
Statement stmt = conn.createStatement();
stmt.execute("select * from cat_municipio");
ResultSet rs = stmt.getResultSet();
while (rs.next()) {
System.out.println(rs.getInt("cve_municipio") + " - " + rs.getInt("cve_sepomex") + " - " + rs.getString("desc_municipio"));
stmt.close();
conn.close();

I don�t obtain nothing.....is like DB table were without information......but in reality the DB table has information.....and I can obtain it with the following JSP:
<!doctype html public "-//w3c//dtd html 3.2//en">
<html>

<head>
<title>Query of Municipalities</title>
</head>
<body bgcolor=#FFFFFF>

Connection conn = null;
try {
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:weblogic:pool:DESAPool");
// Fetch all records from the database in a TableDataSet
DataSet dSet = new TableDataSet(conn, "cat_municipio").fetchRecords();
TableElement tE = new TableElement(dSet);
tE.setBorder(1);
out.print(tE);
} catch (SQLException sqle) {
out.print("Sorry, the database is not available.");
out.print("Exception: " + sqle);
} catch (Exception e) {
out.print("Exception occured: " + e);
} finally {
if(conn != null)
try {
conn.close();
} catch(SQLException sqle) {}

<p>
<font size=-1>Copyright (c) 1999-2000 by BEA Systems, Inc. All Rights Reserved.

</html>
and with this JSP I obtain all the following information:
Municipalities List
CVE_MUNICIPIO CVE_SEPOMEX DESC_MUNICIPIO
1 1 ACAJETE
2 2 ACATENO
3 3 ACATLAN
4 4 ACATZINGO
5 5 ACTEOPAN
Now...I need that the first JSP work very well, because...with that way...I can do queries and obtain the needed results for showing them in the Browser......
So...I hope you understand me, and you could help me please, because I don�t have idea why I don�t obtain the results of a simple query that I am trying to do...thanks.....
Mary
P.D. I also attempted with the following JSP...but the result is the same....I don�t obtain none result...
<!doctype html public "-//w3c//dtd html 3.2//en">
<html>

Urgent. Unable to set up JSP in Weblogic server

          Hi,
          I wish to enable JSPs in the weblogic server. i went thru the bea documentation and
          added the following lines in hte weblogic.properties file :
          weblogic.httpd.documentRoot=XXX (The root directory for the jsps.
          weblogic.httpd.register.*.jsp=\ weblogic.servlet.JSPServlet
          weblogic.httpd.initArgs.*.jsp=\ pageCheckSeconds=1,\
          compileCommand=/opt/java1.2/bin/javac,\
          workingDir=XXX,\
          verbose =true
          After this, i started the weblogic. But apparently, it says that all the above properties are undeclared.
          I am not able to go further on this. Could anyone help me out on this.
          I am working on a HP machine.
          thanks in advance. prashant


Hi,
          It is really hard to tell exactly what is going on without more information. If all you are using are JSPs, try
          removing the servlet classpath altogether. Put any helper classes into the weblogic classpath.
          Can you get one of the example JSPs working in your environment? This would be a good place to start just to verify
          that your environment is set up correctly.
          Can you post your JSP file that is not working?
          Hope this helps,
          Robert

How to modify JSP on Weblogic without restarting a server

Hello,
Could someone explain how to modify JSP on Weblogic without restarting a server?
We use WL 10.2.
I search and modify required jsp on a server, but nothing happens on a Web Browser. I run in Development mode.
Please advice,
Thanks,
Yuri

Hi Yuri,
As you are in Development mode you have one options to use the Auto Deploy folder which can be found in the following path (domain_name/autodeploy).
More information on Auto Deployment check the below link:
http://download.oracle.com/docs/cd/E11035_01/wls100/deployment/autodeploy.html#wp1021626
Other option is to use the following parameter "*page-check-seconds*" in your weblogic.xml file

Upon refreshing the page, why always first.jsp is displayed ?

Hi all,
In case of multipage portlet (jpdk example), why always the first.jsp is displayed upon clicking the refresh button of the page containing the multipage portlet even when we are viewing the second.jsp. Can we avoid this?
Best regards,
Omer

Hi,
As it's visible here Struts 1 doesn't have this component. Although this is 1.3.8 struts version but I doubt if in 1.3.10 TabbedPanel is already implemented. So nothing unusual that it's not working.
To use this component (class) You've to download the latest Struts version (it would be Struts 2 of course) and migrate Your project from Struts 1 to Struts 2. I don't know Struts 1 very well but I read several articles about migration to the latest version and this migration was worth it. Is see this article as very helpful in this case.
And 'struts-tags' is not a class. This a tag library directive that names the library which contains the tags. This uri is declared in a tld file (tag library descriptor) which is special descriptor for the whole library.

          on weblogic. what things i need to include in web.xml and weblogic.xml. Also

Hi,
          I m trying to test a html page on weblogic 6.0. when i type the url
          http://localhost:7001/mytest.html i get following errors. I m not able to
          test any of my jsp pages. I m getting the following error....

Calling property file inside jsp in weblogic.

In JSP file, sometimes, we use the following code in the jspInit()
          <%!
          ResourceBundle resouce =null;
          public void jspInit() {
          resource = ResourceBundle.getBundle("resources");
          %>
          The resources.properties is the file to have the name value pair, which is
          easy to get a list of something.
          Can I still use properties file in my JSP in weblogic? where should I put
          properties? is it weblogic\myserver\under public_html ?
          Thank you for any help.

          I mean to say, put properties file in a directory, which is in Java class
          path.

Head first jsp

hello
i need this book as a soft copy :
head first jsp & servlet.
thanx

To avoid having to use the classpath over and over add it to your system environment variables:
Right click 'My Computer' > Properties > Advanced > Environment Variables
Under 'System Variables' if you don't already have have a 'CLASSPATH', create one. If you do, append the path to your servlet-api.jar ( e.g. c:\Tomcat\common\lib\servlet-api.jar ). Remember, different entries into the classpath must be separated by semi-colons (;).
Save and open a fresh console window ( the changes don't reflect in consoles that were already open ).
Of course, you should still learn how to work with the classpath variable: http://java.sun.com/j2se/1.4.2/docs/tooldocs/solaris/classpath.html
This is what your command should be:
javac -classpath c:\Tomcat\common\lib\servlet-api.jar -d classes src/Ch1Servlet.java

Treat jnlp like jsp in weblogic

I´m trying to treat a jnlp file like a jsp in oracle weblogic. I did this in tomcat, it´s so easy, i need only put a servlet-mapping like that in my web.xml:
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jnlp</url-pattern>
</servlet-mapping>
But in weblogic it don´t works. First, he force me remove this servlet-mapping because he don´t have the same servlet that tomcat and i don´t have a servlet named jsp in my web xml. I wana know if exists any other way to configure my web.xml to treat my jnlp files like a jsp files.
Thanks a lot.

Pre-compile jsp in Weblogic

Hello all,
          I have been trying to add following tags in weblogic.xml to precompile my all jsps at Deployment time, but it gives me error as follows. [I am pasting messages from the console....]
          I am using WL express 7.0 and jdk1.3 that comes along with the server.
          Here is my tag:
          <jsp-descriptor>
               <jsp-param>
                    <param-name>precompile</param-name>
          <param-value>true</param-value>
               </jsp-param>
          </jsp-descriptor>
          What is the wrong here ? Is there any special configuration in weblogic server that I am ignoring here ?

          And make sure you don't have any other patches installed!
          The generated servlet specifically checks to make sure that the servlet is running
          on the same EXACT setup (service pack, patches, etc.) that was used to generate
          it from the original JSP.

Error while parsing JSP with WebLogic 5.1/SP9/JDK 1.2.2

Hello everybody,
          I get the error given below when calling a JSP in a WebLogic

          I know that this error has been reported more than once in these

          - that it occurs only wen running WebLogic 5.1 with JDK 1.3 instead of
          1.2.2
          - that it may also be caused by bad jsp code
          But in my case, it has to be another reason, because
          - I am using jdk 1.2.2
          - the same JSP file is running withour errors on WebLogic 6
          I wonder if it could have something to do with the operating system:
          the parsing error is produced on a Windows version of WL 5.1, while my
          WL 6 which doesn't cause errors is running with Linux.
          Many thanks in advance for any help,
          Eckhard Beisswenger


Once again me!
          After a long time, I stumbled by accident across the answer that solves the problem I described above. It is explained at
          http://support.bea.com/application;JSESSIONID_WLCS_DEFAULT=2R2lzQfEBxFRMX2z0AxeU1Un3N1522I9fCIUI7GfjnjsiSYkPscz
          The clue is that weblogic complains about corresponding get and set methods, when the type of the set methods parameter is different from the return type of the corresponding get method. Unfortunately, the weblogic lexer class gives only a NullPointerException without any hint.

How can I pass a variable value from first jsp page to thired jsp page

In my program ,threr are three jsp pages . I want the first pages's variable value in to thired page .How can I acess.
I used the request.getparameter() ,but when I print the value , null value is getting .

request parameters only last for one request.
To save them longer than that you need to save them somewhere.
Couple of alternatives
1 - store them to session
session.setAttribute("username", request.getParameter("username");
2 - create a hidden field on page 2 and store the value from page 1 there. When you submit page2, you can get it on page3 with request.getParameter again.
<input type="hidden" name="username" value="<%= request.getParameter("username") %>">

Calling a java class in JSP in Weblogic 5.1

Hi
I am trying to call a java class in a jsp page. But it is giving an error:
Compilation of 'C:\weblogic\myserver\classfiles\jsp_servlet\_knet\_buy.java' failed:
C:\weblogic\myserver\classfiles\jsp_servlet\_knet\_buy.java:79: cannot access jsp_servlet._knet.e24PaymentPipe
probably occurred due to an error in /knet/buy.jsp line 25:
e24PaymentPipe pipe = new e24PaymentPipe();
Is this a problem bcos of the wrong path of the class file which i am calling?
Please help this is urgent

<jsp:useBean id="logUsr" scope="session" class="sample.Login" />
When I did like this, everything is ok. No more exception.
If my application has so many java classes under WEB-INF/classes/ without creating package, it may be so inconvenience.
Please kindly let me know why this exception (class not found exception) occurred.
And what is the solution? I cannot deploy the application successfully yet.
