I want to import the packages, for example:
import java.io.PrintWriter;
import java.text.DateFormat;
import java.util.Date;
these packages have already existed so it doesn't pop up any error messages.
When I want to import others packages:
import com.businessobjects.rebean.wi.DocumentInstance;
import com.businessobjects.rebean.wi.Prompt;
import com.businessobjects.rebean.wi.Prompts;
import com.businessobjects.rebean.wi.ReportEngine;
import com.businessobjects.rebean.wi.ReportEngines;
import com.crystaldecisions.enterprise.ocaframework.ServiceNames;
import com.crystaldecisions.sdk.exception.SDKException;
import com.crystaldecisions.sdk.framework.CrystalEnterprise;
import com.crystaldecisions.sdk.framework.IEnterpriseSession;
import com.crystaldecisions.sdk.framework.ISessionMgr;
import com.crystaldecisions.sdk.occa.infostore.IInfoObject;
import com.crystaldecisions.sdk.occa.infostore.IInfoObjects;
import com.crystaldecisions.sdk.occa.infostore.IInfoStore;
import com.crystaldecisions.sdk.plugin.desktop.folder.IFolder;
It will say "the import cannot be resolved", but where I can get the jar files to resolve these problems?
I tried to search these jar files in the java lib folder but was not able to get them.
Can anyone tell the exact folder path for these jar files, if it is there?
Or where can I download those packages.....
I found the website (https://help.sap.com/doc/javadocs_bip_42/4.2/en-US/bip/en/com/crystaldecisions/sdk/exception/package-summary.html) but I still don't know how to import it......
You'll need rebean.wi.adapter.jar and cecore.jar. They are located in the following directory with BO client or server software is installed:
C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib
Note that these are not available publicly -- you will need to install the software.

I am using eclipse for core java and its working fine. Now I downloaded another eclipse for java ee and I am using tomcat server but in my new eclipse java files are not getting loaded
Below mentioned imports are showing the error of import cannot be resolved while they are working fine in my old eclipse(I think there is some problem with build path ) -
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
While the below-mentioned imports do not show any error-
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import com.mysql.jdbc.ResultSet;
Sample Image of error:
A package at the top should be used, a deep src sub-directory like: src/aaa/bbb/ccc.
package aaa.bbb.ccc;
import ...
Reason: using the default package (immediately under the root) is actually
never done since java 1.2. For that I find the missing package suspicious.
The following is wrong:
import com.mysql.jdbc.ResultSet;
It should be:
import java.sql.ResultSet;
Reason for JDBC using database vendor specific libraries is bad style.
Entirely sure on a cause for your errors in eclipse I am not sure. A refresh, Alt+F5 might be useful if the error was a fluke.
If the JDK is actually java 9 I would expect import problems too, as then you would need to gather the JDK modules piecewise. That does not seem to be the case here.
Check if you have set the JDKs correctly in your IDE and in the project.
I have downloaded the library
added the library
refreshed the project
imported the library to project
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;
However i still get the error
The import org.apache.commons.httpclient can not be resolved
can you please tell what is the problem with it?
i need to import java.nio.file.* but cannot find the jar containing this package
I installed new version of jdk 1.8 but still i cannot import this package .Can anybody tell me the jar file containing this package.
Thanks
I think the package want you to import is java input output.
Used this
import java.io.file.*;
Instead of
import java.nio.file.*;
So i made it finally to the final stage of my simple java app that runs under windows and is used to get the user name and log it in an remote excel file. up until now everything is ok.
When i Externelize (does that word exist?) the app to make it a runnable jar the size of the app was 22Mo! wich is huge since i want to use it in an email (outlook).
Here come the question (finally). Can i delete any of the default java jars in the classpath and the app will still run ?? if yes, which ones??
NB: i tried including the imports in the SS if it does help
NB2: the Jar of the app it self is just 20Ko , the ressources are around 22Mo .
By the way thank you all for helping me make this app it was thanks to this website eventhought i didn't ask any question up until now you'll still answered them all..You rock !
Those are my imports:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Iterator;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.MessageBox;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.forms.widgets.FormToolkit;
import org.eclipse.wb.swt.SWTResourceManager;
EDIT: So after the discussions i managed to reduce the size of the app to 8Mo by deleting some of the jar in the referenced library (org.ibm.icu.jar). The app still runs perfectly without it
A jar file is just a zip file, so what I would do is simply unzip the file and see what comes with it and what is large. The standard java libraries, should not even be part of your JAR as they are part of the JRE.
However, my suspicion is that you use Apache POI and that is huge. So if you are writing to an Excel file you might have to stick with that size or find another library.
You could for example write the output as CSV which is very lightweight.
I have a really strange problem.
I want to import two files which are in the package soap. But Eclipse doesn't "see" the files if I want to import them. Even if I change the directory of the file to a package, in which Eclipse sees the other files and is able to import them, these two new .java-files won't show up to import. Even if I try to import it "by-hand", Eclipse doesn't find them:
import ch.asdf.soap.DocumentReply;
import ch.asdf.soap.DocumentRequest;
I've also tried to import the whole package:
import ch.asdf.soap.*;
There aren't any errors in the files.
