adding jar in Jcreator

问题:

I want to read doc file by writing java code in jcreator editor . For this purpose , I want to use Apache POI jar file .

But I don't know how to add jar file in Jcreator editor . My file structure is like this :

Now I am referring using this code .

import org.apache.poi.poifs.filesystem.*;
import org.apache.poi.hpsf.DocumentSummaryInformation;
import org.apache.poi.hwpf.*;
import org.apache.poi.hwpf.extractor.*;
import org.apache.poi.hwpf.usermodel.HeaderStories;

But Jcreator is showing this error to me .

H:\Code For others\chat\docx file\ReadDocFileFromJava.java:1: package org.apache.poi.poifs.filesystem does not exist
import org.apache.poi.poifs.filesystem.*;
^
H:\Code For others\chat\docx file\ReadDocFileFromJava.java:2: package org.apache.poi.hpsf does not exist
import org.apache.poi.hpsf.DocumentSummaryInformation;
                          ^
H:\Code For others\chat\docx file\ReadDocFileFromJava.java:3: package org.apache.poi.hwpf does not exist
import org.apache.poi.hwpf.*;

Why is the Jcreator showing this errors ? What do I do to remove this error ? I am following thus tutorial for doc file reading .

回答1:

1. Highlight the current project:

   

2. Click on the properties button:

   

3. Click on the Required Libraries tab, then click New:

   

4. Give the library an appropriate name, then click Add -> Add Archive:

   

5. Use the navigator to select the .jar file, then click OK on the Set Library window.

6. Ensure the libraries are checked, then click OK:

   

After this, the project should build correctly.

Note

I couldn't locate the library with the exact name yours had, but when I went looking for them I had to download both POI Scratchpad and Apache POI in order to get it working, so pay close attention to exactly which packages aren't found if it still doesn't build when you follow the steps above
